| Outline of Final Research Achievements |
Aiming for a novel method of formative educational assessment, a system for collecting and analyzing participants’ unconscious evaluative acts in social interactions has been developed. The system is automatically to collect learners’ positive/negative reactions to a specific other's acts by means of recognizing whether the reactions are positive or negative based on the actor's short comments and head motions acquired from microphones and motion censors attached on the actors, so that those reactions are collected and summarized for feedback to learners in almost real time.
As a result, the recognition rates of short comments as well as head motions were not good enough. However, since there are strong co-occurrence relations between contents of comments and types of head motion, a method of multi-modal recognition was tried to apply. Consequently, the recognition rates did not reach to the level sufficient for practical use.
