Abstract

L'invention concerne des systèmes d'affichage à détection à touches multiples adaptables, de haute résolution, et des procédés basés sur une réflexion interne totale frustrée qui emploient un guide d'onde optique (12, 32, 42, 62, 76, 84) qui reçoit de la lumière, telle qu'une lumière infrarouge, qui subit une réflexion interne totale et un capteur d'imagerie (20, 50, 72a, 72b, 72c, 86, 104a, 104b) qui détecte la lumière qui s'échappe du guide d'onde optique (12, 32, 42, 62, 76, 84) provoquée par frustration de la réflexion interne totale en raison du contact par un utilisateur. Le guide d'onde optique (12, 32, 42, 62, 76, 84) peut être ajusté avec un recouvrement de surface conforme (48, 64, 78, 88) pour augmenter de manière importante la performance de détection, rendre minimal l'effet de contaminants et l'endommagement à la surface de contact, pour étendre de manière générale la vie du système et pour fournir d'autres avantages. Les systèmes et les procédés fournissent une capacité véritable de touches multiples (entrées multiples) et de résolutions spatiale et temporelle élevées à cause de l'imagerie en continu de la réflexion interne totale frustrée qui s'échappe du guide d'onde optique entier (12, 32, 42, 62, 76, 84). Entre autres caractéristiques et avantages, les systèmes et les procédés sont adaptables pour de grandes installations et sont appropriés pour une utilisation avec une rétro-projection (22, 52, 74a, 74b, 74c) et d'autres dispositifs d'affichage.
