Patent

CA 2476690

A touchpad (30) whereby a user moves a pointing object in either an arc (34) having a large radius (36) to provide coarse input resolution or in an arc (42) having a small radius (44) to provide fine input resolution. The direction of the movement of the pointing object on the arc, either clockwise or counterclockwise, determines if an input value is increasing or decreasing.

L'invention porte sur une touche à effleurement (30) avec laquelle l'utilisateur déplace un pointeur sur un arc (34) de grand rayon (36) pour obtenir une résolution d'entrée grossière, ou sur un arc (42) de petit rayon (44) pour obtenir une résolution fine. Le sens du mouvement du pointeur sur l'arc, horaire ou antihoraire, détermine si la valeur entrée est croissante ou décroissante.
