A Method and System for Monitoring Classroom Concentration of Deaf Students Based on Head Pose Estimation

摘要:

在特殊教育课堂教学场景中,听障生只能通过手语进行教学,通过监测头部姿态可估计课堂专注度,这对优化教学效果具有重要指导价值；为此,设计并实现了基于头部姿态估计的听障生课堂专注度监测系统;首先,搭建了课堂专注度评估框架；然后,提出基于头部姿态估计的欧拉角计算实现单人姿态量化估计；其次,基于余弦函数及采样计算实现了归一化的课堂专注度计算；最后实验结果表明,方法及系统具有一定的有效性和实用性。

Abstract:

In special education classes, deaf students can only receive teaching through sign language. Monitoring head posture can estimate students" concentration in class, which has important guiding value for optimizing teaching effectiveness. Therefore, a classroom concentration monitoring system for deaf students based on head pose estimation was designed and implemented. Firstly, a classroom concentration evaluation framework was established. Then, a method for quantifying the pose of an individual student was proposed, which is based on the calculation of Euler angles using head pose estimation. Next,, a normalized method for calculating classroom attention was implemented based on cosine function and sampling calculation. Finally, the experimental results indicate that the method and system demonstrate a certain degree of effectiveness and practicality.
