インタラクションの為の赤外光源

抄録

Authors have been developing a system in the configuration that use the wearable small projector, retro-reflective material as a screen and infrared light source and camera, to be a feasible configuration in the actual application environment. The screen performed the multiplexed three roles: (1) as the visual output (display), (2) the user handles the screen and screen’s position and orientation is measured using an infrared camera, (3) bright backlight to achieve the clear fingertip image as input. In this paper, a ray-tracing simultion method is applied to develop the efficient infrared light source using LEDs.
