Device for positioning and control of PC cursors and other objects, comprising a control module that can be moved within a defined area (mobility range), where the location of the module within its mobility range is determined by an opto-electronic sensor system. The sensor system incorporates light sources and a reflecting plane (10) that contains two or more grids consisting of non-reflecting stripes (11, 12), where sequences of non-reflecting and reflecting stripes in each grid form groups carrying information about their position relative to a co-ordinate axis, and where position information generated when light beams traverse the grids and reflected light pulses hit photosensors are used to define the position of the control module, which again is used as basis for control of cursors and other objects. |
