A cursor maneuvering device comprises a cavity containing a plurality of colored lights and an image sensor and covered with a light mixing plate. The colored lights are located in the cavity in an as largely departed as possible manner and illuminate a pointing device contacting the surface of the light mixing plate. The image sensor detects a hue of light illuminating the pointing device and controls a cursor depending upon the hue. Changes in the hue of a moving pointing device are translated into movement of the cursor on the display of an electronic device. The pointing device may be anything touching the light mixing plate, for instance a finger.
