Abstract

La présente invention concerne un écran tactile avec des caméras. L'écran tactile comprend un cadre, les caméras, une région de détection de contact et un miroir réfléchissant, le miroir réfléchissant étant monté sur un côté du cadre sans montage de la caméra. Les champs de vision d'au moins deux caméras recouvrent le miroir réfléchissant. Cet écran tactile avec des caméras sans zones exemptes de détection a une structure simple et un faible coût, de sorte qu'elle peut être produite en masse de manière bénéfique.
