Abstract:
1. A portable optical touch system comprising: a first camera device disposed on a corner of a plane, the first camera device comprising: a second camera device movably connected to the first camera device and disposed on the other corner of the plane, the second camera device comprising: a controlling unit electrically connected to the first camera device, the controlling unit being adapted to drive the rotary mechanism to adjust a rotary angle of the first imaging module relative to the second imaging module according to a result of the first adjusting module and the second adjusting module determining whether the first imaging module and the second imaging module are on the same plane, to measure the distance since the first imaging module and the second imaging module are on the same plane, and to analyze the distance calculated by the first measuring module and the second measuring module and the image of the object captured by the first imaging module and the second imaging module for calculating a coordinate value of the object on the plane.
