As the people living in the modern society, there are many extrinsic factors could
result the feeling of pressure. The factors might cause from family, personal economy,
work, et, al. The negative emotion, such as depression, nervousness, anger, sadness,
would be easily induced as people can’t relieve the pressure. Based on the theory of
emotion, there is high causality between negative emotions and physiological events
of human beings. Therefore, how to understand and relieve the personal emotion is an
important topic for modern people. In this study, a home use chip-based physiological
signals measurement device has been developed for measuring the physiological
signals including electromyogram, electrocardiogram, body temperature, galvanic
skin response, and photoplethysmogram. The measured physiological signals are
measured and digitized, and then save to SD card. The LCD board is used for
information displaying. The pictures released from International Affective Picture
System(IAPS) were applied in this study to evoke the emotion of subjects. The feature
parameters were then evaluated from the measured physiological signals. The results
of statistical discriminant analysis showed that the difference is significant between
the four kinds of emotions including happiness, sadness, fear, and disgust for the
normal people and the people with depression-tendency (The score of HAM-D >7).
And the difference is significant as well between the two groups. The device and
software program can be set up for daily activities monitoring of patients. It can be
implemented for patients with psychiatry disease to facilitate the tracking for curative
effects for long-term treatment at home.
