Multi-viewing angle display and touch-panel interface system for collaborative task surrounding round table

摘要

A stereoscopic 3D display delivers stereo-pair images to the appropriate both eyes. This image separating technique can be applied to the dual-views display system. This two-viewing angle display enables two users to provide different images on the screen. Meanwhile, a touch-panel is useful for a computer interface. The advantage of this touch screen is that it is easy for all users to operate intuitively. However a conventional system cannot recognize who touch the screen on a display among users. Especially the dual-views display can provide different images so as not to perceive an upside down image. In the collaborative work surrounding round table among multi-users, it is important to recognize who touched the screen and where was pointed. This paper describes the multi-users' touch-panel interface system which can recognize who touch the screen on a display.
