Tele-Immersive Collaborative Environment with Tiled Display Wall

Abstract

In intellectual collaborative works with participants between remote sites via WAN, CSCW have been used as general communication tools. Especially, the sharing of various, high-quality digital contents such as various materials, computer graphics or visualization contents, and video streaming by between remote places is important to recognize or analyze to easily refer to these contents. However, the image magnification by general projector and large-sized display equipment is low-resolution, and sufficient quality of contents is not obtained. In this research, the author has constructed a tele-immersive collaborative environment with a tiled display wall. In this environment, the author has implemented an application to display high-resolution real video streaming on a tiled display wall in remote place. By using the application, the author displayed the clear video image of remote place over a wide range. Then, the author conducted experimental verification on the effect for eye-to-eye contact by changing the position of camera on frame of LCDs on tiled display wall, and has collected a lot of knowledge. Moreover, the author has tried realistic display processing of high-resolution astronomical observation image and movie data, and it has enabled observation of the entire image of observation data all over tiled display wall.
