摘要 |
A method and a system for determining the position of a radiation emitter, which radiation emitter may be an actively radiation emitting stylus, pen, pointer, or the like or may be a passive, radiation scattering/reflecting/diffusing element, such as a pen, pointer, or a finger of an operator. The radiation from the emitter is reflected from that position toward the detector by a reflecting element providing multiple intensity spots on the detector providing sufficient information for determining the position. From the output of the detector, the position of the radiation emitter is determined. |
