Abstract
We have developed an electronic note system to use digital pen and tablet PC. This system can make a digital note which can establish the link of web address and can embed the images from Internet. Moreover, it can perform group work by sharing the contents of digital note. However, if the previous digital content use in combination with actual paper sheet, it is difficult to handle information all at once. Therefore, we develop a presentation tool to superimpose between real paper and digital information to project back shot of digital contents by small laser projector. Since this system use CCD camera to detect the position of paper, the projection position is adjusted automatically according to the paper position. Moreover, this camera is available for image scanner when the real contents is necessary to use at the group work. In this presentation, we explain the basic function of our developed system, and evaluate the usability and benefit.
