Abstract
An optical touch system is provided. At least one light source is disposed at a side of a base plane. A first optical sensor and a second optical sensor detect a space in front of the base plane to generate a first signal and a second signal. When two groups of objects approach to or touch the base plane, a processing unit determines at least one first portion of the first signal corresponding to the two groups of the objects and at least one second portion of the second signal corresponding to the two groups of the objects, and converts the at least one first portion and the at least one second portion into a plurality of touch regions, and determines group transformations according to positions corresponding to at least part of touch regions. Additionally, a method of touch detection, and a computer program product are also provided.
