Abstract (en)
[origin: FR2899326A1] The method involves arranging a non coherent light emitter (E1) with phototransistor receivers (R1, R2) of TEKT5400 infrared light covering a determined active elementary zone (2) e.g. circle, in proximity to the zone. The emitter and each receiver are enabled to have respective axes (AE1, AR1, AR2) parallel to the zone in which maximum emission and angular sensitivity are observed such that the axes (AR1, AR2) cut the axis (AE1) at different points. The emitter is turned on, and a position of an object (1) e.g. finger, on the emitter is determined as a function of comparison of light signals. Independent claims are also included for the following: (1) an object`s position determining device comprising an emitter (2) a data input terminal comprising an object`s position determining device.
