| Research Abstract |
The purpose of this research was to achieve emotional communication between humans and robots. Numerous attempts have been made by scholars to show that the expressions of feces and voices are effective in receiving and manifesting emotion between humans and robots. Instead of feces and voices, we use body movement as a cue to emotion. We have obtained following results.
We have built a movie database for emotion study. A motion-capturing system was used to get human gait information. 12 sensors were put onto walker's principal joints. Actors were asked to express emotion while walking. The database includes gait information from 30 actors.
We investigated human percept on emotion from gait display. The gait data were presented as biological motion. Human subjects were asked to answer perceived emotion from the display. The rate of correct answer was 40%.
We constructed an emotion-recognition system. A method of feature extraction to discriminate emotions of human from a sensing data of human gait patterns was studied. We assume that the high dimensional biological motion data are generated by low dimensional features which components are statistically independent. The extracted feature is evaluated by a discriminated result of the given biological motion data which identified five types of categories, "Anger", "Grief", "Disgust", "Joy" and "Fear". We achieve 40% accuracy for 5-class of emotion discrimination with 3 actors' biological motion data.
