1. A pointing device for a computer system comprising:
- a first movement sensor, for detecting movements of said device along a first axis and a second axis, which are not aligned;
a second movement sensor, for detecting movements of said device along a third axis not aligned to said first and second axes; and
a processor coupled to said first and second movement sensors for producing a plurality of movement signals indicating the movement of said device along said first, second and third axes, said processor comprising a control stage for controlling a mode of production of said movement signals based on a response of said second movement sensor.

Abstract
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.

11. A method for controlling a pointing device for a computer system, the method comprising:
-
detecting movements of said device along a first axis and a second axis; detecting movements of said device along a third axis not coplanar with said first and second axes; producing a plurality of movement signals indicative of the movement of said device along said first, second and third axes; controlling a mode of production of said movement signals in response to movements of said device along said third axis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A pointing device comprising:
-
a motion sensor configured to detect motion along first, second, and third mutually transverse axes; and a processor configured to produce movement signals indicating a respective movement of said device along the first, second and third axes, the movement signals being configured to cause a visible movement of an icon on a display of a computer, the visible movement corresponding to a movement of the device along the first and second axes, the processor including; a control stage configured to temporarily prevent the movement signals from causing the visible movement of the icon after a movement of the device along the third axis has been detected. - View Dependent Claims (23, 24, 25, 26, 27)
