Corresponding, Transactions of the Virtual Reality Society of Japan, THE VIRTUAL REALITY SOCIETY OF JAPAN, 28, 3, 263-269, 30 Sep. 2023, Peer-reviwed, Thermal displays are desired to enhance virtual reality environments. In this study, a novel non-contact thermal display was proposed, using radiation sources with temperatures higher and lower than that of the human skin surface.The skin surface is warmed or cooled by the transfer of electro-magnetic energy. In the experimental system, a controllable infrared heating lamp and constant temperature ice packs were used as high and low temperature radiation sources, and mechanical shutters were employed to control the radiations with quick responses. The effectiveness of the proposed system was physically confirmed, and by psychophysical experiment, warm and cool sensations were elicited to the users.

International conference proceedings, English - Analysis of conducting waves using multi-channel surface EMG depends on difference in shape of electrodes
Kohei Okura; Tota Mizuno; Marzieh Aliabadi Farahani; Yu Matsumoto; Kazuyuki Mito; Naoaki Itakura
IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 141, 4, 539-545, 01 Apr. 2021, The purpose of this study is to examine the difference in the characteristics of the conducting waves obtained by the difference in the electrode shape and the muscle contraction state. The electrode proposed this time is one in which two kinds of electrodes of different sizes are alternately arranged in a row, eight electrodes each. The analysis was performed using the multi-channel method. From the experimental results, it was found that by making the electrode bigger, the number of conducting waves increases. Although the number of conducting waves was small with a small electrode, it was found that conducting waves of various patterns could be obtained and consider more detailed about muscle contraction.

Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer, 12197 LNAI, 223-232, 2020, In this paper, we propose a training method to improve the stammering symptom, which automatically adjusts the rhythm of speech using vibrational stimulation linked to heart rate through a smart watch. We focus on the rhythm control effect by vibration, confirmed by the tactile stimulation training, and propose a training method to improve the symptoms of stammering while automatically adjusting the rhythm of the utterance based on the heartbeat-linked vibration stimuli. In addition, a system using the proposed method is constructed, and its effects on the heart rate by providing vibration stimulation to stutterers and on stammering symptoms are investigated. We present the effectiveness of stammering improvement training through vibration stimuli by experimenting with eight subjects.

Scientific journal, Japanese - Examination of multi-optioning for CVEP-based BCI by fluctuation of indicator lighting intervals and luminance
Shogo Matsuno; Naoaki Itakura; Tota Mizuno; Kazuyuki Mito
Conference Proceedings - IEEE International Conference on Systems, Man and Cybernetics, 2019-October, 2743-2747, Oct. 2019, In this study, brain-computer interfaces (BCIs) using visual evoked potentials (VEPs) induced by blinking light have been studied. We examined them to change the phase and frequency of the blinking light with variable onset intervals and changing luminance to realize multiple choices in the BCI based on code modulated visual evoked potentials (cVEP) using transient VEP. We used three types of blinking lights with fluctuation interval in addition to one blinking light with fixed interval and attempted to discriminate between the four blinking lights that a subject observed. The amplitude of averaged VEPs with fluctuation interval decreased when a subject did not observe the blinking light. The discrimination rate for the blinking lights was approximately 84%. In addition, we examined the changing luminance of the blinking stimulus to increase the number of multiple choices. In this study, we obtained VEPs based on synchronous addition method and verified the effects of changing luminance and lighting interval in indicators. In addition, our study aims to increase the number of simultaneous choices of cVEP-based BCI using blinking light with variable onset interval and changing luminance. In this paper, we report the possibility of multiple choices by conducting experiments for the estimation of proposed methods.

Tota Mizuno; Daisuke Kirigaya; Mizuo Kimura; Yuichiro Kume
IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 139, 5, 658-661, 2019, Force-like sensations of fingers are evoked by vibro-tactile stimulation applied onto fingertips. This phenomenon is expected to be used for small and simple force displays, since the users wear only small vibrators on their fingertips. In this study, the properties of magnitude of the force-like sensations by vibration were investigated psychophysically, and the activities of finger muscles were measured by digital force gauge. As a result, it was found that the magnitude of force-like-sensation increases, as vibro-tactile stimulation increases.

Advances in Intelligent Systems and Computing, 773, 171-182, 2019, This paper examines an input method for ocular analysis that incorporates eye-motion and eye-blink features to enable an eye-controlled input interface that functions independent of gaze-position measurement. This was achieved by analyzing the visible light in images captured without using special equipment. We propose applying two methods. One method detects eye motions using optical flow. The other method classifies voluntary eye blinks. The experimental evaluations assessed both identification algorithms simultaneously. Both algorithms were also examined for applicability in an input interface. The results have been consolidated and evaluated. This paper concludes by considering of the future of this topic.

International conference proceedings, English - Estimating autonomic nerve activity using variance of thermal face images
Shogo Matsuno; Tota Mizuno; Hirotoshi Asano; Kazuyuki Mito; Naoaki Itakura
Artificial Life and Robotics, Springer Tokyo, 23, 3, 1-6, 04 Jun. 2018, Peer-reviwed, In this paper, we propose a novel method for evaluating mental workload (MWL) using variances in facial temperature. Moreover, our method aims to evaluate autonomic nerve activity using single facial thermal imaging. The autonomic nervous system is active under MWL. In previous studies, temperature differences between the nasal and forehead portions of the face were used in MWL evaluation and estimation. Hence, nasal skin temperature (NST) is said to be a reliable indicator of autonomic nerve activity. In addition, autonomic nerve activity has little effect on forehead temperature
thus, temperature differences between the nasal and forehead portions of the face have also been demonstrated to be a good indicator of autonomic nerve activity (along with other physiological indicators such as EEG and heart rate). However, these approaches have not considered temperature changes in other parts of the face. Thus, we propose novel method using variances in temperature for the entire face. Our proposed method enables capture of other parts of the face for temperature monitoring, thereby increasing evaluation and estimation accuracy at higher sensitivity levels than conventional methods. Finally, we also examined whether further high-precision evaluation and estimation was feasible. Our results proved that our proposed method is a highly accurate evaluation method compared with results obtained in previous studies using NST.

2017 2ND INTERNATIONAL CONFERENCE ON INTELLIGENT INFORMATICS AND BIOMEDICAL SCIENCES (ICIIBMS), IEEE, 189-194, 24 Nov. 2017, Peer-reviwed, For pedestrian traffic, pushbutton traffic signals are used. However, pushbutton signal machines are often installed in inconvenient locations. Therefore, a new method is required to allow pedestrians to switch the traffic signals using a crossing request other than a pushbutton. In this research, we paid attention to the motions of the pedestrians with a crossing request, who tend to "stay and watch the traffic signal in front of the crosswalk." Pedestrian images were captured using a camera built into the traffic signals and analyzed using image processing. A new traffic signal system is proposed that uses the motions of a pedestrian with a crossing request as an input signal.

Journal of Signal Processing,, Research Institute of Signal Processing, Japan, 21, 4, 207-210, 01 Jul. 2017, Peer-reviwed, In the past, many studies have been carried out on eye-gaze input; however, in this study, we developed an eye-glance input interface that tracks a combination of short eye movements. Unlike eye-gaze input that requires high accuracy measurements, eye-glance input can be detected with only a rough indication of the direction of the eye movements, making it possible to operate even terminals with small screens, such as smartphones. In this study, we used an inexpensive camera to measure eye movements and analyzed its output using the OpenCV, an open source computer vision and machine learning software library, to construct an inexpensive and non-contact interface. In a previous study, we developed an algorithm that detected eye-glance input through image analysis using OpenCV, and fed the result of the algorithm back to our subjects. In that study, the average detection rate for the eye-glance input was 76 %. However, we also observed several problems with the algorithm, particularly the problem of false detections due to blinking of the eyes, and implemented solutions for improvement. In this study, we have made improvement with respect to the unsatisfactory detection rate recorded in our previous study, and addressed problems related to user convenience.

電気学会論文誌C, The Institute of Electrical Engineers of Japan, Vol.137, No.4, 616-620, 01 Apr. 2017, Peer-reviwed, Brain-Computer interfaces (BCIs) have been studied by using transient visual evoked potential (VEP) with various blinking stimuli. We examined to change the phase and the frequency of the blinking light with variable onset interval and changing luminance in order to realize multiple choices in the BCI using transient VEP. However, the number of the multiple choices was limited to four choices. Therefore, we examined to change the luminance of the blinking stimulus in order to increase the number of multiple choices.

In addition, we develop multiple choices interface by using blinking light with variable onset interval and changing luminance. In this paper, we report the possibility of multiple choices by experiment of estimate for proposed methods.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 137, 4, 621-627, 2017, Peer-reviwed, The eye gaze input is attracting attention as a method for operating an information device with hands-free. However, it is difficult to use gaze input system over a small screen such as a smart device because eye gaze input method must accurately measure gaze positions. In order to solve this problem, we have proposed the eye-glance input method to use operating a small information device like smart phone. The eye-glance input method is able to input multiple-choice using oblique direction reciprocating movement. Accordingly, enabling an input operation that is independent of the screen size. In this paper, we report result of evaluation experiment of numbers inputting of using our developed a Multiple-choice eye-glance input system that utilized electrooculography that amplified via an AC coupling. As the result of experiments, it was found that the average of the input success rate and the average of the input character number per a minute in real-time eye-glance input at the experimental display design was 91.5% and about 15.2 character for 10 subjects.

It was measured by EOG, but constraint and dedicated apparatus are brought into question. So we proposed non-contact measuring method using camera to measure eye movement. We enabled the eyes movement measurement with internal camera and USB camera by using optical follow in Open CV. In this study, we improve algorithm to measure and give visual feedback to subjects in real time. Then we researched the algorithmic effectiveness and influence by feedback.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 137, 4, 616-620, 2017, Peer-reviwed, Brain-Computer interfaces (BCIs) have been studied by using transient visual evoked potential (VEP) with various blinking stimuli. We examined to change the phase and the frequency of the blinking light with variable onset interval and changing luminance in order to realize multiple choices in the BCI using transient VEP. However, the number of the multiple choices was limited to four choices. Therefore, we examined to change the luminance of the blinking stimulus in order to increase the number of multiple choices. In this study, we try obtained VEPs based on synchronous addition method, and verified effects of changing luminance and lighting interval of indicators. In addition, we develop multiple choices interface by using blinking light with variable onset interval and changing luminance. In this paper, we report the possibility of multiple choices by experiment of estimate for proposed methods.
Scientific journal, Japanese - Development of device for measurement of skin potential by grasping of the device

Communications in Computer and Information Science, Springer Verlag, 713, 237-242, 2017, Peer-reviwed, In this study, we developed a device for measuring skin potential activity requiring the subject to only grasp the interface. There is an extant method for measuring skin potential activity, which is an indicator for evaluating Mental Work-Load (MWL). It exploits the fact that when a human being experiences mental stress, such as tension or excitement, emotional sweating appears at skin sites such as the palm and sole
concomitantly, the skin potential at these sites varies. At present, skin potential activity of the hand is measured by electrodes attached to the whole arm. Alternatively, if a method can be developed to measure skin potential activity (and in turn emotional sweating) by an electrode placed on the palm only, it would be feasible to develop a novel portable burden-evaluation interface that can measure the MWL with the subject holding the interface. In this study, a prototype portable load-evaluation interface was investigated for its capacity to measure skin potential activity while the interface is held in the subject’s hand. This interface, wherein an electrode is attached to the device, rather than directly to the hand, can measure the parameters with the subject gripping the device. Moreover, by attaching the electrode laterally rather than longitudinally to the device, a touch by the subject, at any point on the sides of the device, enables measurement. The electrodes used in this study were tin foil tapes. In the experiment, subjects held the interface while it measured their MWL. However, the amplitude of skin potential activity (which reflects the strength of the stimulus administered on the subjects) obtained by the proposed method was lower than that obtained by the conventional method. Nonetheless, because sweat response due to stimulation could be quantified with the proposed method, the study demonstrated the possibility of load measurements considering only the palm.

Hirotoshi Asano; Kiwamu Goto; Tota Mizuno
Communications in Computer and Information Science, Springer Verlag, 713, 205-209, 2017, Peer-reviwed, The purpose of this study is to develop a biological model between skin temperature change and cooling stimulation to prevent drivers from becoming drowsiness. The traffic accident by an operation mistake or aimless operation has occurred. A factor of these accidents has a driver’s nap. In recent years, many researchers have studied eagerly this theme. The purpose of their studies is to detect a driver’s drowsiness. On the other hand, the aim of our study is to contribute to development of technology for safe drive assistance to maintain a driver’s arousal levels. This technology may give a technical innovation in the relevant area. In general, a change in blood volume in nasal part depends on the vasoconstrictive effect of the sympathetic nervous system along with changes in physiological and psychological conditions. The nasal skin temperature changes depending on the blood flow, thus, the temperature reflects the physiological state. The temperature also decreases as the blood flow in the nasal area decreases during sympathetic hyperactivity. The temperature increases as the blood flow in the nasal area increases due to sympathetic suppression. Previous studies have showed a relationship between nasal skin temperature reflecting autonomic nervous system activity and arousal level. The experiment was conducted to gather data for constructing a biological model of a driver and the relationship between cooling stimulation and nasal skin temperature was modeled with system identification. And the usefulness of models was examined with time response simulation and nyquist diagram. In summary, it is possible to construct biological model based on relationship between thermal stimulation and nasal skin temperature by using ARX, ARMAX and BJ of low order.

Communications in Computer and Information Science, Springer Verlag, 713, 347-352, 2017, Peer-reviwed, In our previous research, we expanded the range to be analyzed to the entire face. This was because there were regions in the mouth, in addition to the nose, where the temperature fluctuated according to the mental workload (MWL). We evaluated the MWL with high accuracy by this method. However, it has been clarified in previous studies that the edge portion of the face, where there is no angle between the thermography and the object to be photographed, exhibits decreased emissivity measured by reflection or the like, and, as a result, the accuracy of the temperature data decreases. In this study, we aim to automatically extract the target facial region from the thermal image taken by thermography by focusing on the temperature distribution of the facial thermal image, as well as examine the automation of the evaluation. As a result of evaluating whether the analysis range can be automatically extracted from 80 facial images, we succeeded in an automatic extraction that can be analyzed from about 90% of the images.

Communications in Computer and Information Science, Springer Verlag, 713, 164-169, 2017, Peer-reviwed, The objective of this study is to develop a multi gesture input interface using several eye motions simultaneously. In this study, we proposed a new automatic classification method for eye blinks and eye movements from moving images captured using a web camera installed on an information device. Eye motions were classified using two methods of image analysis. One method is the classification of the moving direction based on optical flow. The other method is the detection of voluntary blinks based on integral value of eye blink waveform recorded by changing the eye opening area. We developed an algorithm to run the two methods simultaneously. We also developed a classification system based on the proposed method and conducted experimental evaluation in which the average classification rate was 79.33%. This indicates that it is possible to distinguish multiple eye movements using a general video camera.

JOVE-JOURNAL OF VISUALIZED EXPERIMENTS, JOURNAL OF VISUALIZED EXPERIMENTS, 116, Oct. 2016, Peer-reviwed, True, Proprioceptive drift, which is a perceptual shift in body-part position from the unseen real body to a visible body-like image, has been measured as the behavioral correlate for the sense of ownership. Previously, the estimation of proprioceptive drift was limited to one spatial dimension, such as height, width, or depth. As the hand can move freely in 3D, measuring proprioceptive drift in only one dimension is not sufficient for the estimation of the drift in real life situations. In this article, we provide a novel method to estimate proprioceptive drift on a 2D plane using the mirror illusion by combining an objective behavioral measurement (hand position tracking) and subjective, phenomenological assessment (subjective assessment of hand position and questionnaire) with a sophisticated machine learning approach. This technique permits not only an investigation of the underlying mechanisms of the sense of ownership and agency but also assists in the rehabilitation of a missing or paralyzed limb and in the design rules of real-time control systems with a self-body-like usability, in which the operator controls the system as if it were part of his/her own body.

ELECTRONICS AND COMMUNICATIONS IN JAPAN, WILEY-BLACKWELL, 99, 7, 40-47, Jul. 2016, Peer-reviwed, In our previous studies, an eye control input interface using an electrooculograph (EOG) amplified by ac coupling has been developed. We proposed an eye gesture input interface using a combination of several eye movements. It is unnecessary for eye gesture input to restrict head movement, in contrast to conventional eye gaze input. However, it is necessary to use a start operation before eye gesture input. Therefore, eye glance input has been proposed. Eye glance input uses only a combination of eye movements in opposite directions, so that it does not need start operations. However, eye glance input has not always been successful because the algorithm for detection of eye movement from EOG signals was not adapted to slight shifts of the signal baseline. In this study, we propose a new determination algorithm for the eye glance input interface. In experiments using our improved algorithm, we achieved direction determination success rates of over 80% for six subjects. (C) 2016 Wiley Periodicals, Inc.

Artificial Life and Robotics, Springer, 21, 1, 5-10, 08 Jan. 2016, Peer-reviwed, This study aims to evaluate physiological and psychological states using near infrared spectroscopy in noise environments with low or high frequencies. Our system assumes that noise affects brain activity in the frontal lobe. In order to evaluate the subject's states in a noise environment, we constructed an experimental system that measures the subject's states. The experimental method adopted here was borrowed from our previous studies. In the present study, we collected experimental data about the subject's unpleasant or pleasant experiences by producing a noise environment with low and high frequencies. We conclude that noises with low or high frequencies affect our psychological states as well as brain activity in the frontal lobe.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 136, 12, 1785-1790, 2016, Peer-reviwed, We have examined methods to effectively restrain driver's drowsiness by controlling their nasal skin temperature. In resent years, the various kind of techniques for detecting the drowsiness recently has been proposed. In reality, however, these techniques have the problem which influences driver's operation because they already has suitable sleepiness. In our previous study, not almost all drivers became drowsy by promoting sympathetic nerve activity with the ambient biofeedback system. However two drivers became drowsy. This suggests the possibility that the control is not working well as for their physiological responses. This paper aims to examine biological models depending on several physiological responses. We applied the voltage with the regularity to a thermoelectric element attached to driver's neck and measured their nasal skin temperatures. In addition, we made models for driver's physiological responses by taking advantage of the technologies for system identification such as box-jenkins model, auto-regressive exogenous model, state-space model, output-error model and recursive exogenous auto-regressive moving average model. We evaluated the validity of these models by using the fitting rates and board diagram, with the result that model suitable for each physiological response was box-jenkins under the condition of 15 dimensions and a maximum of 30 seconds. It can be concluded that biological model suitable for each physiological response can be made.

HCI INTERNATIONAL 2016 - POSTERS' EXTENDED ABSTRACTS, PT II, SPRINGER INT PUBLISHING AG, 618, 177-181, 2016, Peer-reviwed, This paper proposes a new method for practical skin potential activity (SPA) measurement while driving a car by installing electrodes on the outer periphery of the steering wheel. Evaluating the psychophysiological state of the driver while driving is important for accident prevention. We investigated whether the physiological and psychological state of the driver can be evaluated by measuring SPA while driving. Therefore, we have devised a way to measure SPA measurement by installing electrodes in a handle. Electrodes are made of tin foil and are placed along the outer periphery of the wheel considering that their position while driving is not fixed. The potential difference is increased by changing the impedance through changing the width of electrodes. Moreover we try to experiment using this environment. An experiment to investigate the possibility of measuring SPA using the conventional and the proposed methods were conducted with five healthy adult males. A physical stimulus was applied to the forearm of the subjects. It was found that the proposed method could measure SPA, even though the result was slightly smaller than that of the conventional method of affixing electrodes directly on hands.

COMPUTERS HELPING PEOPLE WITH SPECIAL NEEDS, PT II (ICCHP 2016), SPRINGER INT PUBLISHING AG, 9759, 495-502, 2016, Peer-reviwed, In this paper, we propose a new intention communication assisting system that uses eye movement. The proposed method solves the problems associated with a conventional eye gaze input method. A hands-free input method that uses the behavior of the eye, including blinking and line of sight, has been used for assisting the intention communication of people with severe physical disabilities. In particular, a line-of-sight input device that uses eye gazes has been used extensively because of its intuitive operation. In addition, this device can be used by any patient, except those with weak eye. However, the eye gaze method has disadvantages such as a certain level of input time is required for determining the eye gaze input, or it is necessary to present the information for fixation when performing input. In order to solve these problems, we propose a new line-of-sight input method, eye glance input method. Eye glance input can be performed in four directions by detecting reciprocating movement ( eye glance) in the oblique direction. Using the proposed method, it is possible to perform rapid environmental control with simple measurements. In addition, we developed an evaluation system using electrooculogram based on the proposed method. The evaluation system experimentally evaluated the input accuracy of 10 subjects. As a result, an average accuracy of approximately 84.82 % was determined, which confirms the effectiveness of the proposed method. In addition, we examined the application of the proposed method to actual intention communication assisting systems.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 136, 11, 1581-1585, 2016, Peer-reviwed, We evaluated the temperature change of facial parts as affected by mental work-load (MWL) using infrared thermography. Under MWL, autonomic nerves are active, and the skin surface temperature changes with muscular contraction. In particular, the nasal part of the face experiences the most intense change. Based on this, in previous studies MWL was evaluated by using nasal skin temperature. However, we considered whether other parts of the face experience temperature change under MWL. Therefore, in this study, to identify which other parts of the face experience temperature change, we performed an experiment to acquire facial thermal images when subjects perform a mental arithmetic calculation task. Our results indicate that, in addition to the nasal part, the temperatures around the lips and cheek might also increase under MWL.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 136, 12, 1773-1778, 2016, Peer-reviwed, The aim of this study was to evaluate of muscular fatigue by muscle fiber condition velocity (MFCV) and electromyogram amplitude (RMS) during static and dynamic contractions. Ten healthy male volunteers performed isometric and dynamic exercises. Isometric exercises were at elbow joint angle 50°, 90° and 130° during 40% of maximum voluntary contraction (MVC). Dynamic exercises were at elbow joint angle from 40° to 140° during 40% of MVC and speed was set at 10°/s and 20°/s. Surface EMG signals were measured by using a 15 channel surface electrode array from biceps brachii muscle. As the result, the values of MFCV were decrease with muscular fatigue in static and dynamic contractions and the values of RMS were increase with muscular fatigue in static and bending contraction.

PROCEEDINGS OF THE 2016 IEEE REGION 10 CONFERENCE (TENCON), IEEE, 3798-3800, 2016, Peer-reviwed, A real-time eye-glance input interface is developed for a camera-enabled smartphone. Eye-glance input is one of various line-of-sight input methods that capture eye movements over a relatively small screen. In previous studies, a quasi-eyecontrol input interface was developed using the eye-gaze method, which uses gaze position as an input trigger. This method has allowed intuitive and accurate inputting to information devices. However, there are certain problems with it: (1) measurement accuracy requires accurate calibration and a fixed positional relationship between user and system; (2) deciding input position by eye-gaze time slows down the inputting process; (3) it is necessary to present orientation information when performing input. Put differently, problem (3) requires the accuracy of any eye-gaze measuring device to increase as the screen becomes smaller. The eye-gaze method has traditionally needed a relatively wide screen, which has made eye-control input difficult with a smartphone. Our proposed method can solve this problem because the required input accuracy is independent of screen size. We report a prototype input interface based on an eye-glance input method for a smartphone. This system has an experimentally measured line-of-sight accuracy of similar to 70%.

PROCEEDINGS OF THE 2016 IEEE REGION 10 CONFERENCE (TENCON), IEEE, 3782-3785, 2016, Peer-reviwed, Recently, the input interfaces for the PC using the EEG have been studied. The visual evoked potential (VEP) caused by the blinking light is one of waveforms observed in the EEG signal. The brain computer interfaces which based on the transient VEP (TRVEP) analysis and realized the four choices also have been studied. However, now we have been using a large amplifier and AD board. Furthermore, these two devices are expensive. In this study, in order to solve this problem we developed a small and inexpensive device. In addition, we performed comparative experiments of the conventional device and performance.

PROCEEDINGS OF THE 2016 IEEE REGION 10 CONFERENCE (TENCON), IEEE, 3679-3683, 2016, Peer-reviwed, Recent years have seen rapid widespread adoption of smart devices equipped with a small touch panel. Generally, a software keyboard is problematic despite the use of a small touch panel for input; however, the number of choices and the operational flexibility of the input characters are always equal. This is because an increase in the number of buttons reduces the size of each button, whereas retaining the button size would necessarily reduce the number of buttons. In this study, we propose a new character input interface suitable for a small screen. In addition, we con figured the input interface based on the proposed method, and report the experiments that were carried out to evaluate the interface. As a result, even though the input may be difficult when using the conventional method, the proposed method is hardly considered to influence the input performance.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 136, 12, 1815-1820, 2016, Peer-reviwed, Approximately 50% all accidents are due to carelessness. One reason for these carelessness-related accidents is a temporary decrease in the arousal level due to fatigue or mental saturation after a long period of driving. In particular, a high proportion of accidents on national expressways result in death
hence, fatigue-related accidents involving large vehicles are a serious social concern. Therefore, a quantitative understanding of the physiological and psychological conditions experienced by drivers comprises an important topic in light of preventative safety and accident prevention. The purpose of this study was to develop an autonomic nervous activity-dependent system to inhibit driver drowsiness. We tested this system through several experiments. This study sought to examine the influence of two thermal skin stimulations (cold and warm stimulations) on drowsiness. The experimental results revealed physiological differences in terms of autonomic nervous system activity. The findings suggest that our method for controlling drowsiness is efficient.

The results of those investigations are then used to enhance the VR experience effectiveness. Realities are improved by multi-modal displays featured with motion platform providing visual and inclination information. However, the inclination perception affected by visual stimulation has not been studied sufficiently. In this paper, we have investigated inclination perception in pitch direction affected by the size and velocity of visual objects and human postures. It was found that the velocity of visual objects increases the sensitivity of inclination perception more significantly than the size. In addition, larger interaction between the sight and somatic sensation was observed with sitting posture than with standing posture for the effective information presentation.

FRONTIERS IN PSYCHOLOGY, FRONTIERS RESEARCH FOUNDATION, 6, 6, 1-10, Feb. 2015, Peer-reviwed, True, Vection can be regarded as the illusion of "whole-body" position perception. In contrast, the mirror illusion is that of "body-part" position perception. When participants viewed their left hands in a mirror positioned along the midsaggital axis while moving both hands synchronously, they hardly noticed the spatial offset between the hand in the mirror and the obscured real right hand. This illusion encompasses two phenomena: proprioceptive drift and sense of agency. Proprioceptive drift represented a perceptual change in the position of the obscured hand relative to that of the hand in the mirror. Sense of agency referred to the participants' subjective sense of controlling body image as they would their own bodies. We examined the spatial offset between these two phenomena. Participants responded to a two-alternative forced choice (2AFC) question regarding the subjective position of their right hands and questionnaires regarding sense of agency at various positions of the right hand. We analyzed the 2AFC data using a support vector machine and compared its classification result and the questionnaire results. Our data analysis suggested that the two phenomena were observed in concentric space, but the estimated range of the proprioceptive drift was slightly narrower than the range of agency. Although this outcome can be attributed to differences in measurement or analysis, to our knowledge, this is the first report to suggest that proprioceptive drift and sense of agency are concentric and almost overlap.

Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer Verlag, 9172, 425-432, 2015, Peer-reviwed, We have developed a real-time Eye Glance input interface using a Web camera to capture eye gaze inputs. In previous studies, an eye control input interface was developed using an electro-oculograph (EOG) amplified by AC coupling. Our proposed Eye Gesture input interface used a combination of eye movements and did not require the restriction of head movement, unlike conventional eye gaze input methods. However, this method required an input start operation before capturing could commence. This led us to propose the Eye Glance input method that uses a combination of contradirectional eye movements as inputs and avoids the need for start operations. This method required the use of electrodes, which were uncomfortable to attach. The interface was therefore changed to a camera that used facial pictures to record eye movements to realize an improved noncontact and low-restraint interface. The Eye Glance input method measures the directional movement and time required by the eye to move a specified distance using optical flow with OpenCV from Intel. In this study, we analyzed the waveform obtained from eye movements using a purpose- built detection algorithm. In addition, we examined the reasons for detecting a waveform when eye movements failed.

HCI INTERNATIONAL 2015 - POSTERS' EXTENDED ABSTRACTS, PT I, SPRINGER-VERLAG BERLIN, 528, 727-732, 2015, Peer-reviwed, Since nasal skin temperature is said to provide a good reflection of autonomic nerve activity, nasal skin temperature measurements have been used to assess various human physiological and psychological states, such as pleasant and unpleasant emotions, alertness levels, and mental work load (MWL). In addition, nasal skin temperature has the advantage of enabling non-contact measurement, using such as thermography and radiation thermometers. However, a problem exists with approaches using these device because it is difficult to make accurate assessments if the test subject moves during measurement.
This study aims at resolving this problem via the development of a wearable device that measures nasal skin temperature with small thermopile sensors attached to spectacle frames, thus enabling temperature measurements even when the wearer moves.

International conference proceedings, English - An attempt on quantification evaluation of visual discomfort to the flickering stimuli by using nasal skin temperature
Masafumi Uchida; Tota Mizuno
IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 134, 2, 15-292, 2014, Peer-reviwed, Due to the amplitude-frequency characteristic of the steady-state visual-evoked potential, the flickering frequency of a steady-state visual-evoked potential-based brain-computer interface is typically lower than 20 Hz. However, a visual flicker with a flashing frequency below the critical flicker-fusion frequency often makes subjects feel edgy and causes visual discomfort. This study aims to quantitatively evaluate the relationship between user's visual discomfort and the nasal skin temperature (NST). NST is calculated using the thermal image of the human face. The correlations between the physiological index (NST) and the psychophysical index (based on responses on the visual analogue scale (VAS)) were both considered. The results of VAS are a psychometric response index, which can be used in questionnaires. This study presents a novel technique based on the nasal skin temperature to measure user's visual discomfort. A change in temperature was studied in accordance with the usual method. The results were similar to the known symptoms, which are related to optical sensitivity. Moreover, the frequency characteristics of NST were studied. As a result, the relationship between user's visual discomfort and frequency characteristics of NST dynamics is very strong under 0.01Hz. © 2014 The Institute of Electrical Engineers of Japan.

2014 11TH INTERNATIONAL CONFERENCE ON ELECTRICAL ENGINEERING/ELECTRONICS, COMPUTER, TELECOMMUNICATIONS AND INFORMATION TECHNOLOGY (ECTI-CON), IEEE, 1-6, 2014, Peer-reviwed, In this study, a technique designed to estimate of the autonomic nerve activity with a facial thermogram has been conducted a research and development. Workers feel more mental work-load (: MWL) by advanced information society. Preventing human errors and health hazards with MWL is important. Research activities about MWL, there is the method using thermogram. Thermogram can be taken by non-contact thermometer easily such as a thermography. It can take in the shop floor or life log. But the method needs to measures time-series data at all process of experiment. In addition, if a subject is out of focus of thrmography, it is difficult to estimate MWL. Therefore, measurement environment is limited. In this study, new method are proposed to estimate of the autonomic nerve activity with facial thermogram. If new method with facial thermogram can estimate MWL to high quality, it can use in various situation. Thermograms was taken when a subject solved the issue of a mental arithmetic calculation. And the proposed method has been analyzed by thermograms. As a result of this experiment, proposed method is more sensitive than past technique.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 134, 7, 924-930, 2014, Peer-reviwed, Our previous studies, eye control input interface using an electro-oculograph (EOG) amplified by AC coupling has been developed. We proposed Eye Gesture input interface using combination of several eye movements. It is unnecessary for Eye Gesture input to restrict head movement in comparison with conventional eye gaze input. However, it is necessary to use start operations before Eye Gesture input. Therefore, Eye Glance input has been proposed. Eye Glance input is to use only combination of contrary directional eye movements so that Eye Glance input does not need to use start operations. However, we could not always succeed in Eye Glance input because algorithm for detection of eye movement from EOG signals was not adapted to slight sift of signal base line. In this study, we proposed new determination algorithm for Eye Glance input interface. In experiments using our improved algorithm, we achieved a direction determination success rate of over 80% for 6 subjects. © 2014 The Institute of Electrical Engineers of Japan.

2013 10TH INTERNATIONAL CONFERENCE ON ELECTRICAL ENGINEERING/ELECTRONICS, COMPUTER, TELECOMMUNICATIONS AND INFORMATION TECHNOLOGY (ECTI-CON), IEEE, CD-ROM No.1683, 2013, Peer-reviwed, In this study, a technique designed to enhance virtual reality (VR) effects by stimulating multiple sensations simultaneously is investigated and significant interactions among such perceptions are evoked under various multiple-simultaneous stimulation conditions. To accomplish this, we developed a hand-held multimodal display device capable of presenting visual, weight, and vibrotactile information simultaneously. The device incorporates a liquid crystal display (LCD) panel, a back-mounted moveable weight, and vibration motors in the handgrips. The weight movements are produced by a linear motor controlled by a personal computer (PC). Using this handheld device, it was determined that VR perceptions could be enhanced by the interactions taking place among multimodal perceptions. In this paper, experiments on weight perception along with the affects of vibrotactile stimulation are described. Using our developed handheld vision-tactile-force display device, we investigated the interactions between force and vibrotactile perceptions that were stimulated simultaneously. This indicates that when strong vibration stimulations were given in the direction of weight movement, the weight seemed heavier. The experimental results and conclusions show that weight perception and vibrotactile stimulation could be enhanced using our handheld multimodal display device.

2013 10TH INTERNATIONAL CONFERENCE ON ELECTRICAL ENGINEERING/ELECTRONICS, COMPUTER, TELECOMMUNICATIONS AND INFORMATION TECHNOLOGY (ECTI-CON), IEEE, 1-6, 2013, Peer-reviwed, Tactile sense as one of the five regular senses of human body has always been considered as an efficient substitution for the other senses of body such as sight and hearing. For example, a tactile interface system is able to transfer an essential set of information by using the tactile sense instead of visual or hearing sense. Today we can see the various applications of this substitution in different interface and interactive display systems that are helping people specially the physically challenged ones to perform many of their daily tasks despite of a loss in one of their sensory organs [1]. The concept of tactile apparent movement recognition that have boon considered in this research is normally a subjective sense of human body. The term apparent movement refers to the illusory perception of a movement on skin that is created by the discrete stimulations of a number of points on skin of a part of body that are appropriately separated in space and time and can be controlled by different parameters. These parameters have been studied particularly in this research. Applying the tactile apparent movement to an individually defined engineering system, a quantitative evaluation study becomes necessary and possible. In previous studies, finding the body-sway (testing arm of an experiment subject) caused by the tactile apparent movement in a fixed experimental condition became possible. However, characteristic of the body-sway that appeared in the experiment was not thoroughly investigated. In this study, investigating the body-sway caused by tactile apparent movement in a fixed experimental condition was aimed. Therefore, we focused on 3 group of information; the biological information, the body-sway and the information that resulted from the comparison between the apparent movement recognized trials and the non-recognized trials. The EMG data recorded under particular tactile stimuli was analyzed by performing the time-to-frequency transform tools as the short-time Fourier transform (STFT). The findings of this research will be conducive to optimize the performance of the systems that are using the tactile apparent movement.

Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 8007, 4, 225-234, 2013, Peer-reviwed, Optical measurement devices for eye movements are generally expensive and it is often necessary to restrict user head movements when various eye-gaze input interfaces are used. Previously, we proposed a novel eye-gesture input interface that utilized electrooculography amplified via an AC coupling that does not require a head mounted display[1]. Instead, combinations of eye-gaze displacement direction were used as the selection criteria. When used, this interface showed a success rate approximately 97.2%, but it was necessary for the user to declare his or her intention to perform an eye gesture by blinking or pressing an enter key. In this paper, we propose a novel eye-glance input interface that can consistently recognize glance behavior without a prior declaration, and provide a decision algorithm that we believe is suitable for eye-glance input interfaces such as small smartphone screens. In experiments using our improved eye-glance input interface, we achieved a detection rate of approximately 93% and a direction determination success rate of approximately 79.3%. A smartphone screen design for use with the eye-glance input interface is also proposed. © 2013 Springer-Verlag.

2013 22ND INTERNATIONAL CONFERENCE ON NOISE AND FLUCTUATIONS (ICNF), IEEE, 1-4, 2013, Peer-reviwed, Mental stress has been an issue in modern society. Several studies have investigated the detection of mental stress using physiological indices. However, measurement of these indices would itself impart a certain level of stress to subjects. The temporal dynamics of key typing are called "keystroke dynamics". Keystroke dynamics show variations with psychological subtlety. The objective of this study was to develop a technique for ambient, unconscious measurement of mental stress based on keystroke dynamics. The relationship between fluctuations in keystroke dynamics and cardiac activity, in the form of heart rate variability, was analyzed. Intervals between key strokes were measured while using a computer under conditions of auditory stimulus or cognitive stress was determined. Power exponent beta of the regression curve of the power spectrum for the time series of inter-stroke time (IST), and the power spectrum density of the high-frequency component (HF) for the time series of the R-R interval extracted from electrocardiography were calculated. As a result, the power spectrum of IST approached 1/f with auditory stimulus or cognitive stress, and a significant correlation existed between beta and HF.

Journal of Advanced Computational Intelligence and Intelligent Informatics, Fuji Technology Press, 17, 6, 843-850, 2013, Peer-reviwed, Human-computer interaction is an important field in computer science. One means of such interaction is an eye gaze interface using both optical and electrical methods. Conventional optical devices for measuring eye movement are generally expensive and restrict user head movement. In this paper, we propose a novel eye gesture input interface (EGII) that does not require a head-mounted display. Precise eyemovement in combinations of direction is determined by electrooculographic signals amplified via AC coupling. We also developed and evaluated direction algorithms for determining features of the novel EGII. The best algorithm showed a success rate of 97% in recognizing eye movement in different direction combinations. We also created a small portable measurement device containing a biological amplifier to amplify signals and an A/D board for importing signals. Mean accuracy for the EGII was 95.6% out of 12 possible choices using the selected algorithm and our device. This device can thus be used anywhere and anyone.

In this experiment, we checked things to see DEEP KANSEI appeared in the same domain as precedence research. And based on two experimental results, we detected automatically brain activity and DEEP KANSEI using the multiple regression analysis method. As a result of the experiment, we showed a possibility that the existence of DEEP KANSEI would be automatically detectable from brain activity.

However, a precise elaboration of fluctuations in the secretion of these biomarkers in the time series against stress is not yet clearly illuminated. In this study, we used Chromogranin A (CgA) as a possible biomarker of mental stress for 1) illustrating the precise stress-response in the time series, and 2) investigating a congruity of CgA as the biomarker for mental workloads. (METHOD) In the experiment, ten male university students were inscribed to conduct a simple and easy arithmetic task (T) for 36 minutes with intermission (I) in two different T/I schedule: (A) a set of 18 (T)-9 (I) was repeated 2 times and (B) a set of 6 (T)-3 (I) was repeated 6 times. It should be noted that the total task period and intermission period is the same in both experiment A and B. (RESULT) As a developing result, salivary CgA concentration depicted an increase during the tasks and decrease (recovering) during the intermissions, while such a change was significant and more remarkable in the experiment A. The difference in the rate of increase/decrease induced by the task/intermission was also observed. (CONCLUSION) The stress-response of CgA in the time series plausibly demonstrated the possible candidacy of CgA as a biomarker for a short-term mental workload. In addition such a difference in the increase/decrease rate or time-lag in the responses by loading/unloading of the mental stress would bring forth an apparent difference in observation, thus impairing the effectiveness of CgA as a stress marker, if the assessment of CgA were not close enough.

We developed a four-arm modular robot system which can be configured in a planar structure. A learning mechanism is incorporated in each module constituting the robot. We aim to control the overall shape of the robot by an accumulation of the autonomous actions resulting from the individual learning functions. Considering that the overall shape of a modular robot depends on the learning conditions in each module, this control method can be treated as a dispersion control learning method. The learning object is cooperative motion between adjacent modules. The learning process proceeds based on Q-learning by trial and error. We confirmed the effectiveness of the proposed technique by computer simulation. © 2009 International Symposium on Artificial Life and Robotics (ISAROB).

Artificial Life and Robotics, 14, 2, 209-212, Nov. 2009, Peer-reviwed, A modular robot is composed of multiple modules, each comprising a sensor, an actuator, and a control system. Each module accumulates information about its own sensor, actuator, and connections to other modules, as well as communication information between adjoining modules. The user obtains this information via an interface, and can thus recognize the state of the robot and issue commands. However, when the number of modules becomes large, the amount of information sent from the modules becomes too much for the user to deal with effectively. Naturally, it also becomes more difficult for the user to issue commands to the modular robot as the number of modules increases. In this study, we developed an interface to present, in a simple manner, information aggregated in a certain module from other modules, and we examined its effectiveness in a modular robot composed of these modules. © 2009 International Symposium on Artificial Life and Robotics (ISAROB).

ELECTRONICS AND COMMUNICATIONS IN JAPAN, SCRIPTA TECHNICA-JOHN WILEY & SONS, 91, 4, 27-33, Apr. 2009, Peer-reviwed, The purpose of this study is tactile presentation of figure information by means of modulated vibration based on a short-cycle component T(s)(-1) (40 to 1000 Hz) and a long-cycle component T(l)(-1) (2 to 40 Hz). An effective method for training of the modulated vibration stimulus is proposed and the experimental results on the training and oblivion characteristics of figure discrimination are presented. A training method that integrates tactile and visual stimuli is found to be effective, and it is shown that the association with the frequency change of the long-cycle component is retained in memory longer than that of the short-cycle component.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 129, 4, 11-662, 2009, Peer-reviwed, In the situation in which a robot and a human work together by collaborating with each other, a robot and a human share one working environment, and each interferes in each other. In other ward, it is impossible to avoid the physical contact and the interaction of force between a robot and a human. The boundary of each complex dynamic occupation area changes in the connection movement which is the component of collaborative works at this time. The main restraint condition which relates to the robustness of that connection movement is each physical charactristics, that is, the embodiment. A robot body is variability though the embodiment of a human is almost fixed. Therefore, the safe and the robust connection movement is brought when a robot has the robot body which is well suitable for the embodiment of a human. A purpose for this research is that the colaboration works between the self-reconfiguration robot and a human is realized. To achieve this purpose, a self-reconfiguration algorithm based on some indexes to evaluate a robot body in the macroscopic point of view was examined on a modular robot system of the 2-D lattice structure. In this paper, it investigated effect specially that the object of learning of each individual was limited to the cooperative behavior between the adjoining modules toward the macroscopic evaluation index. © 2009 The Institute of Electrical Engineers of Japan.

The Fourteenth International Symposium on Artificial Life and Robotics 2009, SPRINGER, 14, 2, CD-ROM OS3-5-218, 2009, Peer-reviwed, A modular robot can be built with a shape and function that matches the working environment. We developed a four-arm modular robot system which can be configured in a planar structure. A learning mechanism is incorporated in each module constituting the robot. We aim to control the overall shape of the robot by an accumulation of the autonomous actions resulting from the individual learning functions. Considering that the overall shape of a modular robot depends on the learning conditions in each module, this control method can be treated as a dispersion control learning method. The learning object is cooperative motion between adjacent modules. The learning process proceeds based on Q-learning by trial and error. We confirmed the effectiveness of the proposed technique by computer simulation.

ICBAKE: 2009 INTERNATIONAL CONFERENCE ON BIOMETRICS AND KANSEI ENGINEERING, IEEE, 127-+, 2009, Peer-reviwed, Recent psycho-physiological studies have revealed close relationships between human mental stresses and secretion of hormonal and immunological substances. However, a precise elaboration of fluctuations in the secretion of these biomarkers in the time series against stress; especially against a rather mild stressful task is not yet clearly illuminated. In this study, we used the cortisol, a major glucocorticoid, as a biomarker of mental stress for 1) illustrating the precise stress-response in the time series, and 2) investigating a congruity of cortisol as the biomarker for a mild mental workload. Ten male university students were inscribed to conduct a simple, easy, and monotonous mental arithmetic task for about an hour with intermissions, so as to emulate a mild mental workload. As a result, salivary cortisol depicted an accumulative increase during mild mental workloads, while no marked difference was obtained in the heart rate and its variability. It suggests the slow and long-lasting properties in the stress-response of the cortisol unlike as in autonomous nervous system indices, and therefore plausibly demonstrates the possible candidacy of cortisol as a biomarker for a mild mental load.

We evaluated and examined emotion stress from the nasal skin temperature fluctuation of the space-time with the radiation thermometer. The measured data with the radiation thermometer consists of three kind of factor, because of one point [24±3φ/m] measurement system. Three kinds of factors are temperature fluctuation dependent feelings stress, noise of the radiation thermometer and the other parts which it should measure as the subject moves. We make threshold processing on a change of an area in time of a measurement signal provided in a radiation thermometer. We suggested Differential Revision Filtering (DRF) that a new method use a measurement value of change of one second and a low pass filter go through. By using this method, we got the possibility that decrease movement of a measurement and a noise of measurement device.

However, there has been no objective assessment scale for Deep KANSEI. In this paper, we investigate an objective assessment scale for Deep KANSEI based on psychological and physiological measurements. Firstly, we have evaluated a reproduced sound on Extra HI System M, which is able to highly faithfully reproduce information related with Deep KANSEI associated with music source. Secondly, on the same conditions, we have measured cardiac beat, facial skin temperature and brain wave, then, calculated and analyzed five physiological indexes (LF/ (LF+HF), ΔTmax, gradTmax, α wave, Fm θ wave) by principal component analysis (PCA). Finally, we have discussed relationship between assessment words and physiological characteristics for a sound reproduction. As a result, we have suggested time changing activity of the sympathetic and parasympathetic nervous system as a possible index of an objective assessment scale for Deep KANSEI.

2008 IEEE INTERNATIONAL CONFERENCE ON SYSTEMS, MAN AND CYBERNETICS (SMC), VOLS 1-6, IEEE, 137-+, 2008, Peer-reviwed, Recent psychophysiological studies have revealed a close relationship between mental states of human and secretion of hormones and immunological substances. In this study, we used a major secretory immune substance, secretory Immunoglobulin A (IgA), as a biomarker of stress caused by mental workload. In the experiment, subjects were required to conduct a simple mental workload repeatedly with intermediate break. The result shows that salivary IgA changed according to the work/break schedule in the time series. Moreover, an accumulative IgA change through out this period was observed. We proposed a simple mathematical model to explain this accumulative IgA change. Finally, the result of the experiment and simulation are discussed in relation to the possibility of estimation and/or prediction of subjective stress cause by mental workload; it implies the future development of the self-stress management system.

IEEJ Transactions on Fundamentals and Materials, 126, 6, 470-477, 2006, Peer-reviwed, It has been known that human being exhibits the Fight or Flight Reaction(FFR) when they feel anxiety, strain and threat. This paper describes experiments that were conducted to arouse the fight or flight reaction. Facial skin thermograms in which the temperature fluctuation in specific regions was identified were measured, and the characteristics of the temperature fluctuations in the relevant regions were quantitatively evaluated. The results showed that, for nine of the ten subjects, the FFR was confirmed in the form of reacted areas indicating acute increases in skin temperature, primarily in facial expression muscles such as the procerus muscle and cheek muscles. Additionally, the spatio-temporal spectrum differential analysis method for facial skin thermograms was proposed, and as a result of detecting spatio-temporal skin temperature fluctuations in the facial skin thermograms accompanying manifestation of the FFR, a detection rate of 76.5% was obtained. Thus, the effectiveness of the proposed technique was confirmed.

In this research, we examined the technique evoked body sway to intended direction by vibrotactile stimulation. It is necessary to evoke body sway to intended direction for the assist of postural control. Therefore this study proposes the device creating temporal and spatial tactile stimulation pattern by giving temporal difference among vibrations. We measured the body sway associated with stimulus presentation by using a high-speed camera, stabilometer, and acceleration sensor. We considered the effect of each pattern for the body sway., The Institute of Electronics, Information and Communication Engineers, 13 Jun. 2014, IEICE technical report.

Our previous study, Eye Gesture input interface has been developed. This is eye-gaze input interface using an electro-oculograph (EOG) amplified by AC coupling and a display for guide input. Eye Gesture input interface enables input using combination of twice diagonal eye movement. The advantages of this interface are not expensive, or it is not necessary to fix the user's head movements for the gaze position measurement by using EOG. However, there are weak points that the signal of start operation is necessary, or input in the small screen is difficult. Therefore, Eye Glance input interface available in small screen without the start operation have developed, and we investigated it. As a result, this interface has precision more than 80% was shown., The Institute of Electronics, Information and Communication Engineers, 13 Mar. 2013, Technical report of IEICE.

Recent years, the diffusion of smart phones which are designed based on PC-functions is becoming a trend because of its highly compatible features with the Internet. However, even though the miniaturization of information processing units can be technically achieved, the realization of the interface for the smart phones is becoming more and more difficult due to the limitation of physical size of manipulation by fingers. Therefore, the software keyboard and input interface for the smart phones only are needed. In this study, we proposed a screen design for inputting a lot of possible choices on the screen with a few degrees of freedom for input operation for the use of smart phones. We also proposed two kinds of input interfaces which are a contact input interface through a touch panel and a non-contact input interface by eye movements respectively., The Institute of Electronics, Information and Communication Engineers, 13 Mar. 2013, Technical report of IEICE.

Various eye-gaze input interface are generally expensive, or need to restrict the user's head movements. We had proposed a novel eye-gaze input interface that combined a new display design of interface (Eye Gesture) with an electro-oculograph amplified via an AC coupling. And, realized a small portable system with device of our own making was carried out for miniaturization and low cost. In this study, we have developed an Eye Gesture input interface of portability with using a smartphone.

KAZAMA Yuya; ITAKURA Naoaki; MITO Kazuyuki; MIZUNO Tota
Various eye-gaze input interfaces are generally expensive, and need to restrict the user's head movements. We proposed a novel eye-gaze input interface with electro-oculograph (EOG) amplified by AC coupling. This interface is inexpensive and enables the user to escape the restriction of the user's head movements. However, some user complain of discomfort, because he is applying a paste electrolyte when I stick the electrode. So, we proposed a novel eye-gaze input interface with nano-Tesla sensor. This interface can measure without a paste electrolyte. In this study, we examined how the patch of the magnetic sensor can detect eye movement and wink., The Institute of Electronics, Information and Communication Engineers, 15 Jun. 2012, IEICE technical report.

We had proposed a novel eye-gaze input interface that combined a head mounted display (HMD) with an electro-oculograph amplified via an AC coupling. This interface is not expensive and enables the user to escape the restriction of the user's head movements. And base on this, we proposed a new display design of interface using eye movement of not vertical but diagonal directions to increase the number of selected objects without HMD (Eye Gesture). In this study, in order to realize a small portable system, device of our own making was carried out to biological amplifier for amplification of the signal and AD board for import of the signal. As a result, for the Eye Gesture input interface, the mean accuracies of the choices were 95.6% in the case of 12 possible choices by the device of our own making. And the proposed system for the Eye Gesture input interface can be used in a variety of environments has been shown., The Institute of Electronics, Information and Communication Engineers, 15 May 2012, Technical report of IEICE.

Recently it is the arrival of an information society, the computer and the information processing equipment have spread high-level, it increase more and more at the opportunity which worked a mental activity when a human being performs it. It is called the mental work-load which is a load or a burden by mental work. It is said to be a factor of the human error or the healthy damage of continue MWL. We thought that MWL is the emotion stress because of "Excessive MWL" and "Continuation of MWL" changed a body. And we study the evaluation using a change temperature of difference nose and forehead to the emotion stress with MWL. The purpose of this study is to quantitatively evaluate physiological indexes, which are ECG, EEG, Facial skin thermo image by using adding tasks. As a result, the effectiveness of quantitative evaluation of continue MWL was shown., The Institute of Electronics, Information and Communication Engineers, 17 May 2007, IEICE technical report, 107, 60, 143-147, Japanese, 0913-5685, 110006291533, AN10487237 - 振動刺激によるナビゲーション情報の認知評価—Evaluation of cognition of navigated information evoked vibratory stimulus—MEとバイオサイバネティックス

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (C), We researched to realize an eye glance or electroencephalogram(EEG) input interface that enables input to a portable device using eye glance or EEGs without using fingers. For eye glance input, instantaneous other view (eye glance) was used. For EEG input, lighting interval fluctuation stimulus was used. In the case of eye glance input, it was possible to detect eye glances with a discrimination rate of 90% or more by image analysis using Open CV. In the case of EEG input, it was possible to detect the blinking stimulus that subjects gaze with a discrimination rate of 90% or more by transient type EEG analysis using the lighting interval fluctuation stimulus. Furthermore, we proposed a general purpose design that can input many options with a small number of degrees of freedom as an interface for portable devices, and examined a gesture input method using wrist movement., 16K01538

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Young Scientists (A), In our research group we have studied a method to evaluate and estimate autonomic nervous activity using facial thermal imaging as measured by infrared thermography. Human autonomic nerves change according to various conditions and circumstances. Facial skin temperatures are well affected by the activities of autonomous nerves systems. Transmit autonomic nervous activity information obtained from skin temperature to myself and recognize own condition. We aim to prevent and reduce human errors and associated health hazard. I would like to develop the system that can be used in various situations like EEG and heartbeat.Currently, we are researching and developing three systems. 1. System for evaluating autonomic nervous activity from one facial thermal image, 2. Eye-wear type system, 3. Tracking type system., 15H05323

01 Apr. 2015 - 31 Mar. 2018 - Real 3D-image display by applying the certain projection relation of optics
SHIBUYA Masato; NAKATATE Suezou; MAEHARA Kazuhisa; MIZUNO Tota
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Tokyo Polytechnic University, Grant-in-Aid for Scientific Research (C), By considering the fundamental principle, we have derived the imaging theory which gives us the optics for natural 3D image display. Moreover we have developed this theory to be useful for 3D-dome display and general optics. Being based on our theory, we have practically designed lens and fabricate the real optics. By the difference in vision between the new optics and conventional optics, the effectiveness of our designing method has been confirmed. We think our new proposed method will be useful at least for head-mounted 3D optics., 22560044
