摘要
将计算机视觉中的眼球追踪技术应用到网络学习中,以实现对学生网络学习进行实时监控。首先根据网页浏览模式建立具有信息热点的学习网站,然后借助OpenCV技术追踪眼球移动轨迹,计算出视点在屏幕上的轨迹及注视时长,综合运用这些信息来评判学生的学习状态。实验表明,该方法具有可行性,能够在一定程度上促进网络教学的开展。
The technology of eye tracking in computer vision is applied into online learning to monitor students＇ study. Firstly, according to web scanning mode, a learning web site is set up, it has key inliwmation points. Then moving eys＇s locus is tracked by the OpenCV technology. After doing this, the position and time where students＇ eyes are staring at can be counted. The information mentioned above is very important and can be used to estimate students＇ learning status. It can be concluded from the experiment that the method is feasible and help students study to some extent.
