Document Type and Number:
WIPO Patent Application WO/2019/163339
Kind Code:
A1
Abstract:
A display (14) is positioned to one side of a half-mirror (12), and a sheet-shaped infrared sensor (15) is disposed on said display (14). A first image displayed on the display (14) is formed to the other side of the half-mirror (12) as a second image via the half-mirror (12) and retro-reflective bodies (11, 11a). An infrared beam is radiated toward the second image, and the infrared beam that has been reflected by a pointing means (38) having manipulated the second image and that has passed through the half-mirror (12) and the retro-reflective bodies (11, 11a) forms an image on the display (14). The position at which the image of the pointing means (38) has been formed is sensed by the infrared sensor (15).
