基于眼动跟踪的移动智慧课堂可视交互系统

Visual interaction system of mobile intelligent classroom based on eye tracking

将移动设备运用到教学场景中能有效提升教学质量。为此,基于眼动跟踪技术开发了一个移动智慧课堂可视交互系统,当学生在手机、平板电脑等移动设备上完成课程学习时,设备的前置摄像头采集学生的眼动注视点并生成注视点轨迹图和热区图。教师可通过系统交互界面提供的选项挑选想要查看的学生以及可视化类型,以便实时了解学生的注意力分布和感兴趣区域,进而有针对性地调整教学重点,提高在线课堂的教学质量和效率。用户实验结果证明了该系统的可行性与有效性。

Applying mobile devices to teaching scenes can effectively improve the quality of teaching.Therefore,this paper developed a mobile intelligent classroom visual interaction system based on eye movement tracking technology.When students finish the course learning on mobile devices such as mobile phones and tablets,the front-facing camera of the device will collect students eye movement fixation points and generate fixation point trajectory map and heatmap.Teachers can select the students they want to view and the type of visualization through the options provided by the system interface.It provides convenience for teachers to know students attention distribution and areas of interest in real time,and then adjust the teaching focus pertinently,and improve the teaching quality and efficiency of online classroom.According to the user experiment results,the feasibility and effectiveness of the system are proved.
