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.

International conference proceedings - Discrimination of eye blinks and eye movements as features for image analysis of the around ocular region for use as an input interface
Shogo Matsuno; Masatoshi Tanaka; Keisuke Yoshida; Kota Akehi; Naoaki Itakura; Tota Mizuno; Kazuyuki Mito
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 - Estimating autonomic nerve activity using variance of thermal face images
Shogo Matsuno; Tota Mizuno; Hirotoshi Asano; Kazuyuki Mito; Naoaki Itakura
Artificial Life and Robotics, 23, 3, 367-372, Sep. 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.

電気学会論文誌C, 電気学会, 137, 4, 616-620, 03 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 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 - Eye-movement measurement for operating a smart device: A small-screen line-of-sight input system

IEEE Region 10 Annual International Conference, Proceedings/TENCON, Institute of Electrical and Electronics Engineers Inc., 3798-3800, 08 Feb. 2017, 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-eye-control 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 ∼70%.

Journal of Signal Processing, Research Institute of Signal Processing, Japan, 21, 4, 207-210, 2017, 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.
English - 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.

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.

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.

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.

IEEJ Transactions on Electronics, Information and Systems, Institute of Electrical Engineers of Japan, 137, 4, 628-633, 2017, Peer-reviwed, Our previous studies have proposed Eye Glance input system that is used to only combination of contrary directional eye movements instead of eye gaze input. 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, 639-644, 2017, Peer-reviwed, A diet is possible by various methods now. Recently, the system which enables a partial thin figure by using ultrasonic wave and laser is developed. However, these methods are at risk of a burn or the internal hemorrhage. Therefore, the establishment of the safe method not to destroy a fat tissue is expected. In this study, warm and cold stimulus and vibration stimulus were given in the thigh posterior surface, we examined subcutaneous fat changes over time. We aimed at the establishment of the possible method of the simple and safe diet and fat movement using these external stimulus.

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.

Yuta Ito; Naoaki Itakura; Kazuyuki Mito; Tota Mizuno
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.

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.

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.

Tomohiro Kosuge; Naoaki Itakura; Kazuyuki Mito
ELECTRONICS AND COMMUNICATIONS IN JAPAN, WILEY-BLACKWELL, 98, 11, 9-18, Nov. 2015, Peer-reviwed, Muscular activity is investigated by analyzing the action potential generated by motor units. The multichannel surface electromyogram (EMG) is used to analyze the conduction of muscle potential, which is recorded as the interference electric potential generated by motor units. The multichannel surface EMG includes waveforms that conduct in several channels (conducting waves). We believe that it may be possible to analyze the changes in surface muscle potential caused by muscular activity so as to examine the composition of conducting waves in the multichannel surface EMG. Thus, in this paper, we propose a new method of analyzing the multichannel surface EMG. The proposed method involves quantitatively searching for all conducting waves that appear in the multichannel surface EMG in order to calculate the similarity of the waveforms. Using this method, which is referred to as the multichannel method for conducting waves (m-ch method), various types of data for each wave, including the conduction velocity and amplitude, across channels can be examined. Using the m-ch method, we analyzed the multichannel surface EMG in subjects holding a load. We also examined the changes in the composition of the conducting waves. We believe that muscular activity can be analyzed based on conducting waves from a surface EMG. (C) 2015 Wiley Periodicals, Inc.

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.

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.

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.

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.

JOURNAL OF PHYSIOLOGICAL SCIENCES, PHYSIOLOGICAL SOC JAPAN, 58, 5, 349-355, Oct. 2008, Peer-reviwed, This study examined the effects of a different number of eccentric contractions (ECs) on histological characteristics, surface electromyogram (EMG) parameters (integral EMG, iEMG; muscle fiber conduction velocity, MFCV; and action potential waveform), and isometric peak torque using the rat EC model. Male Wistar rats (n = 40) were anesthetized, and ECs were initiated in the tibialis anterior muscle via electrical stimulation while the muscle was being stretched by electromotor. The rats were grouped according to the number of ECs (EC1, EC5, EC10, EC20, EC30, EC40, and EC100). Three days after the ECs, surface EMG signals and isometric peak torque were measured during evoked twitch contractions via electrical stimulation of the peroneal nerve. The muscle damage was evaluated from hematoxylin-eosin (HE) stained cross sections as a relative number of damaged fibers to intact fibers. Intense histological muscle damage (approximately 50% to 70% of the fiber), loss of isometric peak torque, disturbance of action potential waveform, and depression of iEMG (approximately -60% to -70%) were observed at EC20, EC30, EC40, and EC100. On the other hand, the MFCV did not change in any EC group. Although muscle damage and pathological surface EMG signals were not found at EC10, isometric peak torque was reduced significantly. In conclusion, the extent of histological muscle damage is not proportionally related to the number of ECs. Muscle damage was reflected by iEMG and action potential waveforms, but not by MFCV, which remained unaffected even though approximately 50% to 70% of the fiber demonstrated injury.

MEDICAL SCIENCE MONITOR, INT SCIENTIFIC LITERATURE, INC, 13, 9, CR379-CR385, Sep. 2007, Peer-reviwed, Background: This study investigates coordination of the tipper-limb segments with various external loads by frequeny-domain analysis of physiological tremor (hiring the maintenance of limb positure. Physioloaical tremor is an involuntary), oscillation in every segment of a healthy human.
Material/Methods: A subject raised his right tipper limb forward while extending his hand and fingers. Physiological tremor was measured by acceleration sensors attached to four segments: the index linger, hand, forearm, and upper arm. A balloon filled with helium gas was attached to the forearm as a minus-load condition. A weight band was attached as a plus-load condition. The measured signals were evaluated by frequency-domain analysis: power spectrum and coherence spectrum.
Results: The amplitude of upper-limb tremor measured from the four segments decreased with the minus-load and increased with the plus-load. However, the degree of the variation depended on the. segment. The amplitude of upper-limb tremor measured from the forearm and the hand decreased remarkably with the minus-load, while the amplitude from the tipper ann increased with the plus-load. Although adjacent segments were well coordinated, coordination between the segments varied depending on the external load. The minus-load at the forearm led to a lack of coordination between the tipper arm and the forearm. To compensate for this, the movements of the forearm and the hand became coordinated.
Conclusions: The experimental protocol of this study allowed implementing a method to estimate the physiological modification of the neuromuscular system under a hypo-gravitational environment.

MEDICAL SCIENCE MONITOR, INT SCIENTIFIC LITERATURE, INC, 12, 4, BR115-BR123, Apr. 2006, Peer-reviwed, Background: The distribution of muscle fiber conduction velocity (MFCV) estimated from surface myoelectric signals differs depending on the recording electrode locations. It is assumed in this study that the irregular values of MFCV may be estimated around the end-plate zone and the fiber endings due to effect of unique interference property of myoelectric signals, and its hypothesis is confirmed experimentally and numerically in consideration of the waveform characteristics of surface myoelectric signals.
Material/Methods: In experimental study, the surface myoelectric signals are recorded by array electrodes during voluntary isometric contraction in biceps brachii muscle. In the numerical study, the surface myoelectric signals in consideration of the interference property of some motor unit activities are calculated from the current dipole model which simulated the firing features of muscle fiber from end-plate zone to fiber endings. MFCV is estimated by the technique of cross-correlation. Maximum correlation coefficient (R-xy (T-s)) and amplitude ratio (AAMP(ratio)) are used to evaluate similarity and attenuation rate between traveling signals.
Results: In both results of experimental and numerical studies, the MFCV significantly increase when both R-xy (T-s) and AMP(ratio) decrease around the end-plate zone and fiber endings although three parameters denote constant values in the locations other than the end-plate zone and the fiber endings. The high correlativity is recognized between the experimental and numerical data for MFCV, R-xy(T-s), and AMP(ratio).
Conclusions: Therefore, it is demonstrated by experimental and theoretical studies that MFCV, R-xy(T-s), and AMP(ratio) are influenced by irregular waveform properties dependent on both positions of the end-plate and fiber endings.

Electromyography and Clinical Neurophysiology, 46, 1, 3-16, Jan. 2006, Peer-reviwed, The physiological tremor of the upper limb in three Positions of pronation, neutrality, and supination due to the movement of forearm was measured on four locations at the tip of the finger, the root of the finger in the hand, the wrist, and the elbow with use of an accelerated sensor. The evaluation of the total power, which was the summation of the power spectrum in the frequency range from I to 50 Hz, showed no significant difference in any of the positions. The maintenance of the upper limb at the horizontal level showed the coordination of the central nervous system due to the body parts of the upper arm, forearm, hand, and finger connected by the joint. The coherence spectra showed clear activation of the joint of the wrist in the main peak frequency of around 2.5 and 12.5 Hz in their respective positions. The value of the correlation coefficient in the location between the hand and finger was the largest at over 0.8, and those of the locations which connected the joint of the wrist between the forearm and hand and between theforearm and finger were significantly large with a valuefrom 0. 6 to 0. 8. The mean time (i.e., arrival time) of the transmission from the proximal side (i.e., upper arm and forearm) to the distal side (i.e., hand andfinger) in the upper limb was evaluated quantitatively to be 20 ms for pronation and supination, but the value was small for neutrality.

日本理学療法学術大会, 公益社団法人日本理学療法士協会, 2004, A0458-A0458, 2005, 【目的】振戦は身体の一部あるいは全身に出現する律動的な不随意運動とされている。振戦は健常者の振戦を生理的振戦、疾患者の振戦を病理的振戦とし、その出現状況により安静時振戦、姿勢時振戦、動作時振戦に分類される。手指振戦は通常8-12Hz帯域に主要なピークがあり、このピークは上位中枢由来の振動とされている(Elble and Randall, 1976)。パーキンソン病など上位中枢が障害されるとこの8-12Hz帯域に出現するピークが6Hz付近に低周化して出現する。また、手指振戦の8-12Hz帯域に出現する主要なピークがどのように変化するかを検討することによって、上位中枢の運動調節能が評価できることも報告されている(Makabe and Sakamoto, 2000)。そこで、今回高齢者の手指振戦が年齢によりどのように変化するかを検討した。
【方法】本研究は高齢者健康対策サービスの一環として行われた。対象は介護保険の介護認定を受けていない60歳以上の地域高齢者187名、事前に同意を得た者とした。年齢は60歳代72名、70歳代104名、80歳代11名で平均年齢72歳であった。約75%の対象者がなんらかの病気で通院していた。手指振戦は、第2指先端に加速度センサー（9G110B, NEC三栄）を取り付け測定した。測定時間は1分間で、第2指を視覚的フィードバックにより水平に保持した際の手指振戦を測定した。サンプリング周波数1kHzでAD変換し、測定時間の1分間の前後10秒間を除いた40秒間の時系列データを解析対象とした。時系列データを周波数解析し、FFTよりトータルパワー(1-50Hz)、ARモデルよりピーク周波数を求めた。これらの値が年齢によりどのように変化するかを分散分析、多重比較法により検討した。
【結果】1Hzから50Hzの周波数帯域のトータルパワー値の平均は、60歳代5.16×10-4G、70歳代7.06×10-4G、80歳代4.86×10-3Gで年齢とともに増加する傾向にあった。また、80歳代のトータルパワー値は他のどの年代と比べて有意に増加していた(P < 0.0001)。8-12Hz帯域のピーク周波数の平均は、60歳代9.3Hz、70歳代8.5Hz、80歳代8.6Hzであった。70歳代と80歳代のピーク周波数は60歳代のそれと比べて低下する傾向にあった。
【考察】手指振戦のトータルパワーは振戦の揺れの大きさを表し、8-12Hz帯域のピークは振戦の主要な振動成分を表す。年齢が上昇するにつれてトータルパワーが増加するのは、小脳、大脳基底核系の外発的および内発的運動調節能および視覚や固有感覚によるフィードバック能が低下したためと推察された。また、この影響が8-12Hz帯域のピーク周波数の低周化にも現れているものと考えられた。

Kenichi Kaneko; K. Mito; H. Makabe; M. Takanokura; K. Sakamoto
Electromyography and Clinical Neurophysiology, 44, 8, 455-462, Dec. 2004, Peer-reviwed, Movement-related cortical potentials (MRCPs) associated with the contraction of m. orbicularis oculi related to three types of blinks (voluntary, reflex, and spontaneous) were measured for 12 normal subjects. The purpose of the present study was to estimate the role of the cerebral cortex in close association with the blinks caused by bilateral simultaneous eyelid movements. MRCPs were recorded by surface electrodes placed over the frontal to the parietal regions. The mean amplitude and the duration of the MRCPs for the three types of blinks were evaluated by an averaging technique for each subject. MRCPs for the voluntary blinks were evoked in all subjects. For the reflex and the spontaneous blinks, however, a clear negative rising deflection from the baseline was not obtained. The maximum amplitude of the MRCPs for the voluntary blinks was localized at the vertex region, though there was no significant difference between the durations of the MRCPs for the vertex region and for the other regions. Moreover, the positive potential following the voluntary and the spontaneous blinks was recognized in the parietal region. These results suggest that only the voluntary blinks are caused by the neural activation of the supplementary motor area (SMA), and in addition, the neural activation related to visual recognition is considered to be elicited by the voluntary and the spontaneous blinks.

International conference proceedings, English - On the evaluation of muscle fiber conduction velocity considering waveform properties of an electromyogram in m. biceps brachii during voluntary isometric contraction
Kazuyoshi Mito; K. Sakamoto
Electromyography and Clinical Neurophysiology, 42, 3, 137-149, 2002, Peer-reviwed, The surface myoelectric signal during 20% maximum voluntary contraction was measured in m. biceps brachii using array electrodes for ten subjects in order to evaluate the distribution of muscle fiber conduction velocity (MFCV) in a whole muscle. MFCV was estimated by two calculating methods of the peak maximum method and the cross-correlation method from the myoelectric signals which were processed by techniques of the averaging and the non-averaging. It was found that the values of MFCV depended on the location irrespective of the kind of calculating method used and the kind of processing technique of myoelectric signal. In both the motor end-plate zone and the tendon zone, the values of MFCV showed more than 7.0 m/s. In the regions other than the motor end-plate zone and the tendon zone, the values of MFCV showed about 3.90 m/s which were almost constant. The statistical differences of the values of MFCV were in the same locations measured not recognized between the two calculating methods nor between the two processing techniques. In the cross-correlation method, the relation between MFCV and the electrode location was evaluated by both the maximum correlation coefficient and the amplitude ratio between the different neighboring channels to evaluate the conductive waveform properties of action potentials. The changes of parameters (i.e., MFCV, maximum correlation coefficient and amplitude ratio) depended on the electrode location. The values of MFCV significantly increased in the regions of the motor end-plate zone and the tendon zone, where the maximum correlation coefficient and amplitude ratio significantly decreased. The values of the coefficient of variance (CV) of three parameters in those regions were larger than those in other regions, i.e., the regions other than the motor end-plate zone and the tendon zone. A high maximum correlation coefficient and a high amplitude ratio were necessary for a reliable measurement of the MFCV.

Electromyography and Clinical Neurophysiology, 42, 1, 7-16, 2002, Peer-reviwed, The effect of pressured environment from 1 to 24 ATA (Atmosphere Absolute) on total power spectrum (TP) of physiological tremor, whose value was the sum of power spectra for frequency range in 0.5 ~ 50Hz, was investigated. The main effects obtained were as follows. (1) In the case of 3 ATA, TP during the pressure holding period denoted a similar value as the value in 1 ATA. In the latter half of the period, the TP increased. When the pressured environment is 4 ATA, in which the partial pressure of the nitrogen gas was 3.6 ATA, the TP decreased during the pressure holding period compared with the value in 1 ATA. Nitrogen narcosis was recognized at the partial pressure of 3.6 ATA, thus the effect denoted a decrease of TP. (2) In the cases of 16 and 19 ATA using heliox gas, during the pressure holding period, TP decreased compared with the value in 1 ATA, but in the case of 24 ATA the value increased. The partial pressure of helium gas of 23.6 ATA indicated a high pressure nervous syndrome, therefore, the influence of high pressure on TP was recognized as one of the causes of the increase of TP. (3) The influence of inhibitors of the autonomic nervous system on TP during the pressure holding period of 3 ATA was recognized. After intake of the inhibitor for the parasympathetic nerve (atropine) during the pressure period, TP increased, while for the intake of the inhibitor for the sympathetic nerve (propanol), TP decreased.

International conference proceedings, English - Distribution of muscle fiber conduction velocity of m. masseter during voluntary isometric contraction
K. Mito; K. Sakamoto
Electromyography and Clinical Neurophysiology, 40, 5, 275-285, Jul. 2000, Peer-reviwed, Muscle fiber conduction velocity (MFCV) is the velocity of an interference wave due to muscle fiber action potentials. In general, it has been reported that the value of MFCV in m. masseter is larger than that in limb and trunk muscles. But the values of MFCV in the reports were measured in part of the muscle, and the distribution of MFCV in the whole muscle including the end-plate and the tendon has not been measured. In this study, surface myoelectric signals are recorded in m. masseter during voluntary isometric contractions of 20, 30, and 40% MVC (maximum voluntary contraction) in eleven healthy male subjects with the use of array electrodes. The value of MFCV is found directly using an averaging method. The end-plate zone is concentrated in the lower quarter of the muscle. The distribution of MFCV depends on the location of the measured electrode. The largest value of MFCV of more than 20.0 m/s is obtained in the locations of the end-plate and the tendon. The minimum value of MFCV is obtained at the location of 10 mm measured from the end-plate along the direction of the muscle fiber to the tendon of the upper side. The mean values with the standard deviations during 20, 30, and 40% MVC are 10.3±0.7, 11.6±0.7, and 12.2±0.8 m/s, respectively. The MFCVs between the different neighboring locations are compared and found to be significant by a level of 1% for each contraction level. The MFCVs increase depending on the contraction levels for various electrode locations on the muscle.

Electromyography and Clinical Neurophysiology, 40, 3, 151-161, Apr. 2000, Peer-reviwed, Changes of muscle fiber conduction velocity (MFCV) detected by surface array electrodes during an isometric contraction and the recovery period were evaluated. The location on skin measured for action potentials of muscle fiber in m. biceps brachii was a distance of 5 mm and 30 mm from the end-plate to the distal tendon. The MFCV was evaluated by averaging raw EMG waves. The MFCVs at both locations declined gradually during the loads of sustained isometric contractions of 30, 50, and 70% of the maximum voluntary contraction (MVC). The degree of the decrease of the MFCV was extremely intense during a sustained contraction of 70% MVC. The values of the MFCV at the location of 5 mm from the end-plate in the period close to the exhaustion state showed a significant decrease compared with the values in the initial period during the contractions for the above three kinds of loads, while the decrease of the MFCV at the location of 30 mm from the end-plate was not found to be so significant during the contractions. In the recovery period, the contraction of 5% MVC was maintained, and the resultant MFCVs restored gradually to the value of the initial period. At the location of 5 mm from the end-plate, the MFCVs at 15 minutes after the end of the load were significantly higher than those just after the end of the load. At the location of 30 mm from the end-plate, the increases of the MFCVs during the recovery period did not show significant changes. Changes of the MFCV during the isometric contraction and the recovery period depend greatly on the location of the electrodes measured for the action potentials of the muscle fibers.

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.

Potential of waves observed in a surface electromyogram (EMG) signal is summarized with a lot of motor unit action potentials. Therefore, we thought that we could discuss mechanism of muscle construction with separately observing characteristics of every conducting wave in surface EMG signals. In our previous study, we developed a judgment of conducting wave, that is, a method to extract conducting waves from multi-channel surface EMG signals over several adjacent channels with considering waveforms between adjacent channels. In this study, we proposed a new judgment of conducting wave with considering not only waveforms but also conductive wave distance. We discussed a usability of the new judgment by means of observing the characteristics of conducting waves., The Institute of Electronics, Information and Communication Engineers, 15 Jun. 2012, IEICE technical report.

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.

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.

KOIZUMI Kyohei; ITAKURA Naoaki; MITO Kazuyuki
Brain-computer interfaces (BCIs) using visual evoked potentials (VEPs) induced by blinking photic stimuli have been researched. In our previous study, presentation methods for blinking photic stimulus and analysis methods for the VEP have been studied to extract the adequate characteristics of the VEP for realizing the BCI. In this study, we proposed to use blinking photic stimuli with different phase and to utilize the phase information as well as the power information of FFT for the VEP. Two blinking photic stimuli with different phase were used on the same display in our experiment and availability of the phase information of FFT for the VEP was examined. From the results, it was found that the phase information was available for the BCI to discriminate between two VEPs during gazing at two blinking photic stimulus with different phase., The Institute of Electronics, Information and Communication Engineers, 12 Dec. 2010, IEICE technical report, 110, 355, 47-50, Japanese, 0913-5685, 110008676709, AN10091178 - Examination of brain-computer interface with multi-possible-choices by single 10Hz blinking photic stimulus using a transient VEP analysis
YAMANISHI Nao; ITAKURA Naoaki; MITO Kazuyuki
Generally, a brain-computer interface (BCI) using a visual evoked potential (VEP) has been realized by means of discriminating a peek frequency of a steady-state VEP induced by blinking photic stimuli at the frequency of around 10 Hz. Therefore, it was necessary to use blinking photic stimuli with different frequencies and the same number of possible choices. However, the frequency of blinking photic stimuli induced the VEP is limited. In this study, we examined the possibility of a BCI with 3 possible choices by only single 10 Hz blinking photic stimulus. For realizing this BCI, it is necessary to discriminate among the 3 VEPs during gazing at the center, the right side, and the left side of photic stimulus. From the results, it was found that the accuracies of discrimination between the 2 VEPs during gazing at the right side and the left side of photic stimulus was high by utilizing the transient VEP analysis., The Institute of Electronics, Information and Communication Engineers, 11 Nov. 2010, IEICE technical report, 110, 294, 47-50, Japanese, 0913-5685, 110008153913, AN1001320X - Effect of Pictogram Size and Pattern in Tactile Recognition
MITO Kazuyuki; AIGA Ken; ITAKURA Naoaki
An availability of pictogram in the tactual map was examined. Eleven sighted people volunteered and experiment was performed under an eye mask. Seven kinds of pictograms were used in this study. The volunteer touched the pictogram displayed on the tactile graphic display and answered the name of its pictogram and they learned the pictogram by the haptic exploration. After the learning, volunteer touched the pictogram of other size. The accuracy rate, conviction degree, cognitive time and intelligibility were evaluated in this task. Before the learning, in the pictogram with previous knowledge, the accuracy rate was increased and the learning time was decreased. After the learning, accuracy rate was about 100% regardless of the size of pictogram. Both cognitive time and intelligibility were changed by size and complexity of the pictogram., The Institute of Electronics, Information and Communication Engineers, 21 Sep. 2010, IEICE technical report, 110, 211, 25-28, Japanese, 0913-5685, 110008107023, AN1001320X - The influence of blood flow restriction during muscle fatigue and recovery
HIKAGE Chihiro; MITO Kazuyuki; ITAKURA Naoaki
Recently, low-intensity exercise training combined with KAATU training (restriction of muscular venous blood flow from the limb muscles) can result in significant and rapid increases in muscle size and strength in the arm and thigh muscles. This study examined how blood flow restriction influence muscle fatigue and muscle recovery. We measured changes in surface EMG during elbow isometric exercise at 20 and 40%MVC in blood flow restriction condition and non-blood flow restriction condition. Eight adult male subjects were examined. The result suggests that restricted condition's influence is bigger low intensity exercise than the high-intensity exercise., The Institute of Electronics, Information and Communication Engineers, 23 Jun. 2010, IEICE technical report, 110, 111, 5-8, Japanese, 0913-5685, 110007890141, AN1001320X - Judgment of Conducting Wave with considering Coefficient of Variation of Conduction Velocity in Multi-Channel Surface EMG signals

We examined the effect of high heel shoes on kinematic and kinetic walking parameters in healthy skilled and non-skilled users during stair descent by using three-dimensional motion analysis and floor reaction force. There was a tendency to give priority to the speed rather than the stability in the skilled. The result suggested that the load to the knee and ankle joints was increased in the high heel stair walking., The Institute of Electronics, Information and Communication Engineers, 14 May 2010, IEICE technical report, 110, 52, 25-29, Japanese, 0913-5685, 110008000938, AN1001320X - Characteristics of biological vibration of living body and its application to welfare engineering

Itakura Naoaki; Mito Kazuyuki; Mizuno Tota; Matsuno Shogo; Akehi Kota
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, Fuji University, Grant-in-Aid for Scientific Research (C), We studied on a characteristic of lower limb muscle activities in elderly persons after the ergometric pedaling exercise for a month. To estimate the effect of the exercise, the surface electromyography (SEMG) of lower limb muscles were subjected to Daubechies-4 wavelet transformation, and mean wavelet coefficients were compared with the pre-exercise and the post-exercise in each wavelet level.For the elderly persons, the mean wavelet coefficients as an energy of muscle activities during the pedaling movement were significantly decreased in the tibialis anterior (TA) and the gastrocnemius medialis (GM) by the pedaling exercise. On the contrary, the mean energy of wavelet levels of -2 and -3 (125-250 and 62.5-125 Hz) within the rectus femoris (RF) and the biceps femoris (BF) were significantly increased in the healthy young persons. These results suggest that the effect of the pedaling exercise is different from the effects of heavy-resistance trainings as a power training., 26350669

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), In the present research, the time-sequence for Aikido-fundamentals among Aikido practitioners was analyzed by taking the biomechanical approaches. The main results were as follows: 1) In Katatedori-kokyuho, for most practitioners from 1st to 6th-dan, breath-out was observed while the switching step occurred concurrently with the arm lifting, followed by a breath-in. In this lifting stage, the advanced group (over 3rd-dan) performed the technique with a constant angle in the elbow, while the 1st-dan group bent and stretched the elbow. Therefore, these factors effected on the energy transmission onto the Uke. 2) In Tenkan-movement,the downword movement of center of gravity in mastery group (from 4th to 7th-dan) were smaller than value in beginners (under 1st-dan) at the primary stage. Furthermore, the range of center of pressure (COP) in the sole became smaller with increasing Aikido skill level. These facts during training can be used to make the teaching more efficient., 25350718
