Abstract:
There is provided an optical touch system including at least one lighting unit, at least one image sensing module and a processing unit. The image sensing module is configured to capture light of a pointer and the lighting unit to generate a two-dimensional image and to convert entire of the two-dimensional image to a one-dimensional feature. The processing unit positions the pointer according to the one-dimensional feature.
