An input device (10) for detecting input with respect to a reference plane (24). The input device (10) includes one or more light sensors (16,18) positioned to sense light at an acute angle with respect to the reference plane (24) and for generating a signal indicative of sensed light, and a circuit (20) responsive to said light sensor for determining a position of an object with respect to the reference plane (24).

L'invention concerne un dispositif de saisie destiné à détecter la saisie par rapport à un plan de référence. Le dispositif de saisie comprend un ou plusieurs capteurs de lumière positionnés de manière à capter la lumière au niveau d'un angle aigu par rapport au plan de référence et afin de produire un signal indicatif de la lumière captée, ainsi qu'un circuit répondant à ce capteur de lumière afin de déterminer une position d'un objet par rapport au plan de référence.
