Abstract

Currently, the one-to-many teaching method is still adopted among most of the teaching classroom in modern universities. Limited by the resources of teachers, the number of students in some basic courses could be well into the hundreds. In this teaching situation, it is difficult for teachers to notice learning feedback from all student immediately. This paper proposed a real-time feedback system based on the array camera to obtain facial expressions of all students and judge the teaching effect of the knowledge points. This system can help the teacher handle the learning state of the students dynamically, so that the teaching methods or progress can be adjusted to achieve better teaching effect.
