얼굴 인식에 의한 각성도 측정에 관한 연구 = A study on the measurement of arousal level by face movement

다국어 초록 (Multilingual Abstract)

The purpose of this study was to define emotions in the degree of arousal by distinguishing the specific features in facial expressions. A web camera was used to obtain images for extracting the coordinates of features in eyes, eyebrows, and mouths. Seven major factors that dictated the degree of arousal were drawn out by calculating the distances and angles of the coordinates. Of the factors, five factors were finally determined by a pre-test. Mapping the data in facial expressions onto subjective evaluations was tried to elevate the validity. Participants were three undergraduates of Sangmyung University, not visually handicapped. Two sets of relaxing and arousing movies were presented to each subject. Each movie popped up on the screen in order of relaxing, arousing, relaxing, and arousing movies every 90 seconds with rest for 70 seconds. The degrees of arousal in their facial expressions changed by the stimuli were measured. Each participant was asked to score what they felt in the degree of arousal. The rating was on a 1-to-7 Likert scale. Then, the two data was compared by drawing a matrix. The concordant rate of 75% between facial expressions and subjective evaluations was confirmed. This study was significant in that the approach to analyzing the degree of arousal in facial expressions and to comparing it with subjective judgments was carried out. The result gained from this study is expected to help define emotions in the degree of arousal. More studies on facial expressions of emotions in the aspects of valence and arousal dimensions should be followed in the future.
