Patent ID: 8920240

Claim:
A game controller having an actuator mobile in rotation in relation to a fixed part, in such a way as to simulate a control of the rotation of a steering column of a simulated vehicle, comprising : at least a motion production system comprising a rotatable part which is mobile in rotation in relation with the fixed part and a non-rotatable part which is not mobile in rotation in relation with the fixed part, the rotatable part of said motion production system and the non-rotatable part of said motion production system being substantially coaxial, wherein said motion production system generates displacement in rotation of the rotatable part in relation to the non-rotatable s part by elasticity or electromagnetism, means for detecting the displacement in rotation of the rotatable part of said motion production system comprising at least one Hall effect or magnetoresistive effect detecting unit, constituted of at least two elements, of which a permanent magnet and a magnetic sensor, in that, at least during the rotation of said actuator, the actuator is integral in rotation with the rotatable part of said motion production system, and in that, at least during the rotation of said actuator, a first of said elements is integral in rotation with said actuator and is fixed in relation to the rotatable part of said motion production system, and in that, at least during the rotation of said actuator, a second of said elements is integral in rotation with said fixed part and is fixed in relation to the non-rotatable part of said motion production system, in such a way both the angular displacement of the rotatable part of said motion production system with respect to the fixed part being identical to the angular displacement of the rotatable part of said motion production system with respect to the non-rotatable part.
