In this research, mode of viewing, preference, and excitement-calm to TV contents were estimated from the hemodynamics parameter to create the estimation model. As physiology indices, the cardiovascular system was assessed by mean blood pressure (MP), heart rate (HR), stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR). Comfortable, arousal, vigor, preference and concentration to TV contents were assessed by visual analog scale (VAS) for mental indices. Psychological excitement-calm to TV was assessed by up and down arrow key of a keyboard in real time. Based on the above indices, the estimation model was created by using the neural network. As a conclusion, the distinction rate of the preference and the mode of viewing were each obtained to 83.3% and 75.0% at the maximum. The average error of the excitement-calm was obtained to 17%。

The aim of this research was development of emotion still camera. Emotion still camera is used to record the image of KANSEI of the photographer at the moment of shooting a photograph. Physiological and psychological measurements of the photographer were performed at the moment of the photography. Three situations where photographer generally took a photograph were defined. The three situations had the time factor, the spatial factor and the psychological factor. Blink and peripheral skin temperature (PST) and heart rate (HR) and pupil diameter were measured with camera operation. KANSEI was evaluated by the physiological - psychological indices.  There was more the number of blinks in the time factor than general number of blinks. The average of PST in the time factor fell in comparison with the usual PST of the photographer. The average of HR in the time factor was increased in comparison with others. It was thought that the result was caused by the sympathicotonia of photographer strained by the time factor.

In this paper, the objective assessment scale for Deep KANSEI evoked by high quality sound reproduction was investigated in the following experiments.(1) Subjective evaluation of the quality of musical sound reproduced by two different systems. One was a conventional system and the other was the Extra HI System M which could reproduce superior high quality sound by characteristics of precision wave front and planar wave.(2) Measurement of the nasal skin temperature, which is known to be an index of autonomic nervous system activity. Results showed that a greater pleasant feeling seemed to be evoked in the Extra HI System M condition compared to the condition of the conventional sound reproduction system. The long-term decrease of the nasal skin temperature, which strongly correlates to sympathetic nervous activity, showed a correlation with the subjective evaluation implying the possibility of objective assessment scale for Deep KANSEI.

Emergent emotions under gustatory stimuli was quantitatively evaluated with the facial skin thermogram. The nasal skin temperature was correlated with the subjective emotional status measured by the visual analogue scale. Transition to unpleasant status was inhibited with sweet gastatory stimulus.

The objective of this study is to objectively evaluate the subjective complexity by change in oxygenated hemoglobin and hemodynamics for the developing the relief method of stress based on improving preference by subjective complexity. The change in oxygenated hemoglobin concentration (ΔoxyHb) and hemodynamic parameters as physiological indices and psychological intensity as psychological indices were measured when performing the four auditory stimuli repeatedly. As a result, comfort and subjective complexity indicated the inverted “U” shape function. The tendency of the correlation between ΔoxyHb and subjective complexity was categorized into three main types. Significant differences of stress coping were found by hemodynamics. It was clarified that physiological responses to subjective complexity were assessable objectively.

This paper proposes a concept of the adaptive asynchronous human machine system (Async-HMS) which maintains asynchronous periodic operations against user's actions for avoiding user intention. In order to find the dynamics of the operation period presented by Async-HMS, discrimination thresholds of the operation period were obtained by psychophysical experiment. According to the thresholds, three levels of fluctuation of the operation period were defined as ‘constant’, ‘unrecognizable’, and ‘recognizable’. Psychophysiological measurement was conducted on the performance of the synchronized key typing task by the three levels of the operation period. A synchronization error as performance index, the hemodynamic parameters as indices of autonomic nervous system's activity, and the amount of the senses as psychological indices were evaluated. As a result, monotonous feeling was eliminated without compromising the performance in case of `unrecognizable' fluctuations in the operation period presented by Async-HMS.

A digital book has become popular along with the popularization of electronic medium. It is needed that assessment of not only subjective assessment about readability or usability, but also objective assessment of psychosomatic health impact. The objective of this study is an objective assessment of physiological and psychological effects of reading books using electronic or paper medium. This paper focused on hemodynamic parameters. The measurement item was VAS and POMS as a psychological index and hemodynamics parameters as a physiological index. As a result, low vigorous and unreadable were significantly recognized (p<0.05) in reading a book using an electronic medium comparing with a paper medium. Cardiovascular system became active coping because of sympathetic hyperactivity in the hemodynamic reaction. By contrast, using an electronic medium did not fit into stress coping. It was also found that parasympathetic nervous system enhanced with illegibility of the sentence and fatigue by usinig an electronic medium. For all of these results, it became identified a difference in a way to manage in physiologically with reading a book using an electronic and paper medium.
