Abstract
The invention relates to movement-givers, especially for controlling the cursor of a computer, with a body-movement sensor pair for the determination of a relative body surface movement and sensor movement. It is provided here that the body has an after-glowing surface, that the movement sensor has a light source for the generation of an after-glowing spot on the body surface, the body-movement sensor pair being constructed for a relative movement of the after-glowing surface and of the light source, and the movement-sensor comprises, further, a position-sensitive photo-detector which is designed to detect the position of the after-glowing spot.
Claims18
Movement-giver with a body-movement sensor pair that includes a body and a movement sensor for determining a relative movement of a body surface and of the movement sensor, characterized in that the body surface defined by the body comprises an after-glowing surface, the movement sensor has a light source for the generation of an after-glowing spot on the body surface, the body movement sensor pair is constructed for a relative movement of the after-glowing surface and of the light source, and the movement sensor further has a position-sensitive photo-detector which is designed to detect the position of the after-glowing spot.
Movement-giver with a movable body and a movement sensor for the detection of a body rotation movement, characterized in that the movable body has an after-glowing surface and the movement sensor has a light source for the generation of an after-glowing illumination spot on the movable body, and a position-sensitive photo-detector that enables it to track the movement of the after-glowing spot on the surface of the movable body.
