Abstract

L'invention concerne un dispositif d'affichage (1) comprenant un dispositif de pointage (6, 14), tel qu'une manette. La pression exercée sur le bras de la manette produit un signal électrique indiquant la direction et l'amplitude de la force appliquée. Le dispositif de pointage peut être commuté entre deux modes: un mode déplacement de curseur et un mode défilement. En mode de fonctionnement déplacement de curseur, le signal électrique est traduit en une certaine vitesse et en une certaine direction de déplacement de curseur. En mode de fonctionnement défilement, le signal électrique est traduit en une direction principale de défilement et en une certaine vitesse de défilement.
