项目摘要

The purpose of this research is to develop a collaborative learning system for home use by interconnecting geographically distributed study desks via broadband network. For instance, the system 1) supports awareness of remote friends, 2) enable participants to share a physical material, 3) and later allow a participant to review previously undertaken sessions.In order to realize the first function, we proposed the method to detect a user's work rhythm and express the rhythm by verbal expressions. Furthermore, using the RFID technology, we proposed to estimate subjects that a user studied by detecting textbooks on a desk. We expect that such information can be used as a trigger to start studying together.In order to realize the second function, we developed a document camera that enables remote pointing with a remote controlled spotlight. Based on the experiments with the system, we further developed a document camera which consists of a LED projector and high resolution CCD camera. The system not only enabled to share the image of a document but also allowed a remote participant to draw lines on the document using the tablet PC and then project such lines directly on to the document.In order to realize the third function, we first proposed to detect conversational features and calculate the candidate times for replaying the video. Also, by printing a unique 2D marker on each document, a remote user's drawings are related to the marker. Thus the drawings can be recalled later just by placing the document on the document camera.

这项研究的目的是通过通过宽带网络互连的地理分布式研究书桌来开发用于家庭使用的协作学习系统。例如，系统1）支持对远程朋友的认识，2）使参与者能够共享实物材料，3），后来允许参与者审查先前进行的会话。为了实现第一个功能，我们提出了检测方法用户的工作节奏，并通过口头表达表达节奏。此外，使用RFID技术，我们提出了估计用户通过在书桌上检测教科书进行研究的主题。我们希望这样的信息可以用作触发器，可以开始一起研究。为了实现第二个功能，我们开发了一个文档摄像机，该摄像头能够远程指向遥控的聚光灯。根据系统的实验，我们进一步开发了由LED投影仪和高分辨率CCD相机组成的文档摄像头。该系统不仅可以共享文档的图像，还允许远程参与者使用平板电脑在文档上绘制线路，然后将此类行直接投射到文档上。为了实现第三个功能，我们首先建议检测会话特征并计算重播视频的候选时间。同样，通过在每个文档上打印一个唯一的2D标记，远程用户的图纸与标记有关。因此，稍后只需将文档放在文档摄像头上，就可以召回图纸。
