Method of controlling a cursor by measurements of the attitude of a pointer and pointer implementing said method

A three-dimensional (3D) pointing device configured to control a cursor on a display surface, the pointing device comprising:

• one or more of an accelerometer, a gyroscope and a magnetometer;
• an access to a computing resource, said computing resource configured to execute computer code instructions characterized by a rule of transformation of one or more second parameters to one or more first parameters by using one or more intersections of a straight line carried by a vector p with a projection surface, said projection surface being predetermined and distinct from the display surface, wherein:
• said one or more first parameters characterize the cursor and are chosen from a group comprising displacements, position and orientation of said cursor on the display surface;
• said one or more second parameters characterize a frame of reference tied to the pointing device and are chosen from a group comprising attitude, position and angular velocity of said frame;
• and
• the vector p of the pointer is tied to said frame of reference.
