Abstract
An optical touch system includes an image sensor for detecting at least one object and a processor coupled to the image sensor. The processor is configured to determine the number of pixel clusters created by the at least one object on an image generated from the image sensor and to generate gesture information when the number of pixel clusters is greater than a predetermined pixel cluster number.
