Smart Classroom

教育是引入信息媒体技术的前景广阔的领域之一。然而，在日本的大学里，最主要的教育方式是教师和学生在教室里面对面交流的授课方式，这种授课方式不应该受到电脑的干扰。为了将信息媒体技术引入教室，例如，为了记录讲座内容以便之后重复使用，而不干扰教师和学生之间的面对面交流，计算机不应该明确地出现在教室中，而是隐藏在教师和学生之间。我们把这种在用户需要支持的时候给予支持，同时在用户不注意的情况下观察用户的信息系统称为“环境媒体”。本研究要实现的系统名称Smart Classroom是Environmental Media for Classroom。本研究重点研究了课堂视频的录制和分发功能，并将这些视频的重用作为智能课堂的期望功能之一。研究课题包括：(1)提出智能教室作为教室环境媒体的概念；(2)课堂各种情境的识别；(3)教室照明的控制；(4)人脸图像处理的应用；(5)视频压缩与传输；(6)课堂档案展示；(7)系统实用化开发；(8)系统评价。我们将本研究开发的系统应用于我校以实际教育为目的对学生进行的讲座中，以评估系统的进一步改进。研究的进展是由系统的完善和通过实际使用对其进行重新评估所构成的过程的重复推动的。该系统获取的数据，包括讲座视频、幻灯片图像、讲座白板文字等，不仅本身可以作为大学教育的数字内容，而且形式更加丰富。我们目前正在讨论该系统的商业可行性。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
