Display system and method utilizing optical sensors
First Claim
1. A display system, comprising:
- an arrangement of optical sensors, positioned behind an at least partially transparent surface such that fields of view of at least two adjacent sensors are partially overlapped;
a display device, between said arrangement of optical sensors and said surface;
a light emitting system configured for emitting light outwardly through said surface; and
a processing unit, configured for analyzing pixelated image data received from said sensors to identify light interferences by objects in front of said surface, controlling said display device based on said analysis, and removing said overlaps by calibrating each optical sensor to ignore light interferences in portions of the respective sensors'"'"' field of view that are overlapped by adjacent sensors.

Abstract
A unified input and display system and method for enabling sensing interferences made by a user (such as touch or hovering) using multiple interference techniques and instruments. One system comprises: a touch screen that enables emitting and guiding light to enable a user to input drawings by physically interfering the light emitted therefrom and displaying of the interference therethrough; a sensing system comprising a multiplicity of optical sensors arranged according to a predefined layout positioned in relation to the touch screen in a manner that allows the sensors to sense light arriving from the touch screen and translate the sensing into frames each including a pixilated image data of the sensed light; and a screen unification module enabling to unify frames sensed by the sensors at a given moment into a single screen reading comprising a unified whole-screen pixilated image data.
