Abstract

La présente invention concerne un dispositif d'entrée d'informations de position ne permettant pas de trouver une position par la détection du déplacement relatif entre le corps principal et un plan à l'aide d'une boule ordinaire ou de techniques optiques, mais permettant de trouver une position par la détection d'une direction de rotation à l'aide d'un accéléromètre. Le dispositif comprend également un organe de déplacement du curseur par le calcul de la valeur d'impulsion par rapport à un certain service, et non pas par l'utilisation d'un accéléromètre ordinaire.
