Abstract
La présente invention concerne une plage de lecture tactile pouvant contenir plusieurs lignes de caractères Braille ou un réseau régulier de plusieurs lignes et colonnes de points constituant un écran graphique tactile, dont la faible épaisseur lui permet de remplacer ou de compléter l'écran visuel d'un ordinateur portatif. Chaque élément tactile comporte un point tactile (16) fixé élastiquement sur une tige (1) mobile verticalement, deux ressorts (11) et (14) disposés de façon à constituer pour la tige (1) un système de rappel élastique à deux positions stables, l'une haute pour faire apparaître le point au dessus de la surface de lecture (21), l'autre basse pour le faire disparaître sous cette surface, deux fils en alliage à mémoire de forme (22) et (28) dont la contraction, provoquée par échauffement électrique, déplace la tige (1) et le point (16) de leur position haute vers leur position basse ou vice-versa.
