Patent ID: 8717315

Claim:
A touch-control system, comprising: a touch-control panel having a touch surface and adopting a touch-sensing structure, the touch-sensing structure comprising a plurality of first conducting wires paralleled to each other; a first image sensing apparatus; a second image sensing apparatus, the first and second image sensing apparatus being used for sensing a plurality of images of the touch surface; and a processing circuit electronically coupled to the plurality of first conductive wires, the first and second image sensing apparatuses, when a first pointer and a second pointer touch the touch surface, the processing circuit acquiring the one-dimensional coordinates of the pointers by the first conducting wires as a first sensing result, the processing circuit calculating possible touch positions of the pointers based on the images of the pointers sensed by the first and second image sensing apparatus as a second sensing result, and further acquiring intersection of the first sensing result and the second sensing result, taking this intersection as the actual touch positions of the first and second pointers.
