中文摘要：

课堂上对学生听课效果进行评估的重点是捕捉学生听课行为。本系统利用Kinect传感器获取学生听课过程中的彩色、深度、骨骼点图像来分析学生的上课肢体状态、注意力方向,以此反映学生听课状态。同时,系统利用Kinect麦克风阵列采集到的声源信息来统计课堂回答问题的频度和声源位置。通过对上述信息的综合分析,获取学生上课状态的客观指标,从而对课堂教学评估提供数据支撑。

英文摘要：

The key to evaluate the listening quality is to monitor the students＇ behavior in classroom. This system uses color, depth, and skeleton point image obtained by Kinect sensor to analyze limb state, attention direction, so as to reflect listen state. Meanwhile, the system count of frequency of answering questions in class and sound source location according to sound source information, which is collected by microphone array equipped in Kinect. Through comprehensive analysis on above information, the system can get some objective index of listening state to make data support for classroom teaching evaluation.
