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.

本研究的目的是透过宽频网路将分散在不同地理位置的学习桌连结起来，发展一个家庭使用的协同学习系统。例如，该系统1）支持远程朋友的意识，2）使参与者能够共享物理材料，3）并允许参与者回顾先前进行的会话。为了实现第一个功能，我们提出了检测用户的工作节奏并通过语言表达来表达节奏的方法。此外，使用RFID技术，我们提出了估计的主题，用户研究通过检测教科书在桌子上。我们希望这些信息可以作为开始共同学习的触发器。为了实现第二个功能，我们开发了一种文档相机，可以通过遥控聚光灯进行远程指向。在实验的基础上，我们进一步研制了一台由LED投影仪和高分辨率CCD摄像机组成的文档摄像机。该系统不仅能够共享文档图像，还允许远程参与者使用平板电脑在文档上绘制线条，然后将这些线条直接投影到文档上。为了实现第三个功能，我们首先提出检测对话特征并计算回放视频的候选时间。此外，通过在每个文档上打印唯一的2D标记，远程用户的绘图与标记相关。因此，稍后只需将文档放置在文档相机上即可调用绘图。
