| Abstract |
The ratio of aged class has been increasing gradually not only in Korea, but also in the world since several years ago. As a result, many unexpected social problems started to now. The burden charged to this society is to solve those problems; how to take care of that aged people, how to offer jobs to them, etc. It means that the study about the aged class should be done soon. Due to that need, this thesis is wrote out. The aim of this thesis is to detect the emotion of aged people and establish a certain algorithm for detecting it. In the whole process of experiment and analysis, I used HRV(Heart Rate Variability) data since the heart is a representative which is controlled by the ANS(autonomic nervous system), and the ANS reflects the changes in emotion. After stimulating the aged people with the authorized pictures which induce different emotions each. 1 measured HRV of those aged. The HRV data is then analyzed in the two domain area, time and frequency. 1 guessed that the result would show some certain differences according to the pictures and it was shown from the experiment. Seeing the result, HRV was changed by what the aged felt looking at the pictures. Then it also means that visual stimulation influence on the has of the aged people. |
