Abstract

L'invention concerne un clavier, fondé sur la vision par ordinateur, conçu pour entrer des textes, chiffres, caractères, sur des ordinateurs, blocs-notes électroniques et autres dispositifs comprenant des microprocesseurs. Ce clavier peut être réalisé à partir de papier, plastique, polymère, comportant l'image d'un clavier normal dans lequel les emplacements des caractères sont marqués en tant que régions non chevauchantes. L'utilisateur recouvre le caractère ou les emplacements de caractères à l'aide de ses doigts ou d'un pointeur, cette action étant enregistrée par une caméra reliée à l'ordinateur. Les caractères recouverts par les doigts ou les pointeurs sont reconnus au moyen de techniques de vision par ordinateur, par analyse des images vidéo produites par la caméra. Etant donné cette conception, le clavier fondé sur la vision par ordinateur ne nécessite ni antenne ni câble de connexion le reliant à l'ordinateur.
