Development and Practice of Acquisition and Visualization System of Behavior of Lecturers and Students in Lecture Room Videos

在本研究中，我们开发并利用了教师和学生行为的采集和可视化系统，以反映和修改高等教育中的讲座，我们检测的集中气氛，从图像特征，如面部方向。我们开发了可视化系统的活动在每个人或组和时间过渡的基础上选择面板的聚焦对象的视频。此外，我们还开发了学生的三维可视化界面，以支持讲座分析。我们开发并使用了响应分析器，使学生能够在课堂上轻松地进行陈述。我们使用我们的系统分析讲座视频。

In this research, we develop and utilize acquisition and visualization system of Behavior of Lecturers and Students in order to reflect and revise lectures in higher education.We detect atmosphere of concentration from image feature such as facial direction. We develop visualization system of activity in each individual or group and time transition based on selecting panels of focusing objects on the video. Moreover, we develop interface of 3D-visualization of students for supporting lecture analysis.We develop and utilize response analyzer that enable students to make statement easily during a class. We analyze lecture videos using our system.
