Abstract: A pointing and control device for a computer system includes: a body (9) that can be manoeuvred by a user; and an inertial sensor (12), fixed to the body (9), for supplying first signals (S AX ', S AY ', S AZ ') correlated to the orientation of the body (9) with respect to a gravitational field ( G ) acting on the inertial sensor (12). The device moreover includes: a magnetometer (11), fixed to the body (9) for supplying second signals (S MX ', S MY ', S MZ ') correlated to the orientation of the body (9) with respect to the Earth's magnetic field ( M ) acting on the magnetometer (11); and processing modules (17, 18; 317) for determining an orientation (A, X', Y', Z') of the body (9) in an absolute reference system (X, Y, Z; G , P, N), fixed with respect to the Earth's magnetic field ( M ) and gravitational field ( G ), on the basis of the first signals (S AX ', S AY , S AZ ') and second signals (S MX ', S MY ', S MZ ').
