Abstract

Ce dispositif de lecture (1) d'imprimés à entrée optiques, destiné aux malvoyants ou aux aveugles, permet à l'ulitisateur de faire passer un ensemble souris (2) contenant une caméra (25) sur le texte à lire. Les images de ce texte sont introduites dans un ordinateur (3) qui les décode en leur sens symboliques par reconnaissance optique (31) de caractères. En assemblant des mots provenant d'éléments textuels en chevauchement, on recrée des ensembles complets. En utilisant également le signal de sortie concernant la localisation des caractères propre à la reconnaissance optique de caractères (31), l'ordinateur (3) commande un afficheur tactile linéaire (53) situé dans l'ensemble souris (2), ce qui indique à l'utilisateur la présence et l'alignement vertical d'un texte alphanumérique reconnu placé sous l'appareil. Cette rétroaction permet à l'utilisateur de placer, d'aligner correctement et de guider l'ensembe souris (2) sur le texte à lire. De plus, grâce à un synthétiseur vocal (61), les mots sont prononcés de façon audible quand ils sont parcourus. Comme ce dispositif peut s'utiliser d'une seule main, ses utilisations portent sur la lecture d'emballages alimentaires, de flacons de pilules, de billets de banque, d'étiquettes de prix ainsi que d'imprimés. En version portative, ce dispositif permet aux malvoyants et aux aveugles de mener une vie quotidienne plus riche.
