INFORMATION DISPLAY SYSTEM AND PROGRAM, AND OPTICAL INPUT SYSTEM, PROJECTION-TYPE IMAGES AND DISPLAY APPARATUS |
摘要 |
An information display system includes a pointing device and a control apparatus for detecting the locus of tip of the pointing device. The pointing device includes a light emitting part for irradiating the radiated light that radiates with the tip of the pointing device as the center on a predetermined plane. A camera captures images of a region including the radiated light on the predetermined plane. A radiated light detector detects the radiated light from the images captured by the camera. An estimation unit estimates the position of the tip of the pointing device from the radiated light detected by the radiated light detector. |
