Abstract
A pointing and control device for a computer system, the device having a body that can be maneuvered by a user; and an inertial sensor fixed to the body for supplying first signals correlated to the orientation of the body with respect to a gravitational field acting on the inertial sensor. The device moreover includes a magnetometer fixed to the body for supplying second signals correlated to the orientation of the body with respect to the Earth's magnetic field acting on the magnetometer and processing modules for determining an orientation of the body in an absolute reference system, fixed with respect to the Earth's magnetic field and gravitational field on the basis of the first signals and second signals.
