Abstract
A system and method of controlling a cursor (120) in a surface (100) by measurements of attitude of a pointer (110). The measurements can be provided by inertial, optical, magnetic, ultrasound, radiofrequency or video means and appropriate processing means. The method includes a step of computing the displacements of the intersection of a vector tied to the pointer with a projection surface. The projection surface can be predetermined on the basis of the measurements of the attitude and/or of the angular velocity of the pointer. The pointed-at surfaces can be planes, cylinders or spheres. The pointing can be performed in limited fashion or by sliding. The control of the cursor, in absolute mode or in relative mode, can allow the triggering of functions controlled by the orientation of the cursor on the pointed-at surface.
