Paper Abstract

This paper describes 360 degree viewing display system that can be viewed from any direction. A conventional monitor display is viewed from one direction, i.e., the display has narrow viewing angle and observers cannot view the screen from the opposite side. To solve this problem, we developed the 360 degree viewing display for collaborative tasks on the round table. This developed 360 degree viewing system has a liquid crystal display screen and a 360 degree rotating table by motor. The principle is very simple. The screen of a monitor only rotates at a uniform speed, but the optical techniques are also utilized. Moreover, we have developed a floating 360 degree viewing display that can be viewed from any direction. This new viewing system has a display screen, a rotating table and dual parabolic mirrors. In order to float the only image screen above the table, the rotating mechanism works in the parabolic mirrors. Because the dual parabolic mirrors generate a "mirage" image over the upper mirror, observers can view a floating 2D image on the virtual screen in front of them. Then the observer can view a monitor screen at any position surrounding the round table.
