Abstract

L'invention concerne un procédé et un dispositif tactiles pour une image projetée. L'invention appartient au domaine technique de la projection et s'applique à un dispositif de projection comprenant un panneau tactile et un écran d'affichage. Le procédé comprend les étapes consistant à : selon la résolution d'un panneau tactile et la résolution d'un écran d'affichage, obtenir une deuxième région tactile correspondant à une première région tactile pour une image affichée par l'écran d'affichage; obtenir une proportion d'affichage transversal m et une proportion d'affichage longitudinal n entre l'image affichée par l'écran d'affichage et une image actuellement projetée; déterminer une troisième région tactile correspondant à la deuxième région tactile sur l'image actuellement projetée, d'après la proportion d'affichage transversal m et la proportion d'affichage longitudinal n; analyser une instruction tactile d'après la troisième région tactile et l'image actuellement projetée; et répondre à l'instruction tactile pour l'image actuellement projetée selon le résultat de l'analyse. Un panneau tactile correspond précisément à une image actuellement projetée et l'image actuellement projetée peut donc être précisément contrôlée.
