POINTING DEVICE FOR A COMPUTER SYSTEM WITH AUTOMATIC DETECTION OF LIFTING, AND RELATIVE CONTROL METHOD

摘要

A pointing device for a computer system includes: a first movement sensor for detecting movements of the device (1) along a first axis (X) and a second axis (Y); a second movement sensor, for detecting movements of the device (1) along a third axis (Z) not coplanar with the first and second axes (X, Y); and a processing unit (6) associated to the movement sensors for producing a plurality of movement signals (A_X, A_Y, A_Z, V_X, V_Y, V_Z, P_X, P_Y, P_Z) indicating the movement of the device (1) along the first, second, and third axes (X, Y, Z). The processing unit (6) includes a control stage (15), for controlling the production of the movement signals (A_X, A_Y, A_Z, V_X, V_Y, V_Z, P_X, P_Y, P_Z) on the basis of a response (S_Z, A_Z) of the second movement sensor (5b).
