A pointing device for a computer system includes: a first movement sensor for detecting movements of the device along a first axis and a second axis; a second movement sensor, for detecting movements of the device along a third axis not coplanar with the first and second axes; and a processing unit associated to the movement sensors for producing a plurality of movement signals indicating the movement of the device along the first, second, and third axes. The processing unit includes a control stage, for controlling the production of the movement signals on the basis of a response of the second movement sensor.
