Design and Implementation of a Facial Expression Response Analysis System
This study implemented a facial expression analysis system. The system can capture facial images of students via webcam and analyze facial expressions of students towards learning contents with different difficulties and a relationship between social interaction and learning effectiveness. The system selected ten face feature points for identification of 11 facial action units. Then these action units are classified into positive, neutral and negative social interactions by using a rule-based expert system.
