A system for entering multi-dimensional position data for computer is proposed, comprising a position data sender device having at least one light source able to emit a light pulse, and a position data receiver device (4) comprising at least two photo receptor elements (20, 21) for detecting the light coming from the said light source and a calculating part (22) for calculating a three-dimensional position of at least one part of the position data sender device (5) in space from the quantities of light detected by the said photo receptor elements (20, 21). <IMAGE> |
