Smart Classroom

教育是引入信息媒体技术的一个很有前途的领域。然而，日本大学最主要的教育方式是通过课堂上师生之间的面对面交流实现的讲座，这种交流不应该受到电脑的干扰。为了将信息媒体技术引入课堂，以便在不干扰教师和学生之间的面对面交流的情况下，例如将讲座录制下来供以后重复使用，计算机不应该明确地出现在教室里，而应该隐藏起来，不让老师和学生看到。在观察用户而不被用户注意的情况下，当需要支持时，我们将向用户提供支持的信息系统称为环境媒体。本研究所要实现的系统名为智能教室，即教室环境媒体。本研究的重点是讲课录像和分发…的功能更多的是将这些视频作为智能课堂的预期功能之一进行重复使用。研究课题包括：(1)提出作为教室环境媒介的智能教室的概念；(2)识别各种授课情况；(3)教室照明控制；(4)人脸图像处理的应用；(5)视频压缩和传输；(6)授课档案的呈现；(7)实际使用的系统的开发；(8)系统的评价。将本研究开发的系统应用于我校实际为学生提供的教育授课中，对系统的进一步完善进行评估。研究进展是由系统改进和通过实际使用重新评估所构成的过程的重复推动的。该系统获得的数据，包括讲座视频、幻灯片图像和讲座中的白板书写，不仅可以作为大学教育的数字内容，而且可以以更丰富的形式使用。我们目前正在讨论该系统的商业可行性。较少

Education is one of the promising field for introducing information media technology. However, the most dominant style for education in Japanese universities is lectures realized by face-to-face communication between teachers and students in classrooms, which should not be interfered by computers. For introducing information media technology to classrooms in order to, for example record lectures for their reuse afterwards, without interfering face-to-face communication between teachers and students, computers should not explicitly appear in classrooms but hide themselves from the teachers and students. We call the information system that gives supports to its users when those supports are necessary while observing the users without being noticed by the users "Environmental Media". The Smart Classroom, which is the name of the system aimed to be realized in this research is Environmental Media for classrooms. This research focuses on the function for taking videos of lectures and distri … More buting those videos for their reuse as one of the functions expected for Smart Classroom. The research topics include, (1) proposing the concept of Smart Classroom as Environmental Media for classrooms, (2) recognition of various situations of lectures, (3) control of lighting in classrooms, (4) application of facial image processing, (5) video compression and transmission, (6) presentation of lecture archives, (7) development of the system for practical use, (8) evaluation of the system. We applied the system developed in this research to the lectures that are actually given to the students for real educational purpose in our university in order to evaluate the system for its further improvement. The research progress was driven by the repetition of the process constituted by improvement of the system and its re-evaluation through practical use. The data obtained by the system, which include videos of lectures, images of slides and writing of whiteboard in the lectures, can be used as digital contents for university education, not only in itself but also in more enriched forms. We are currently discussing commercial viability of the system. Less
