Abstract
An optical multi-touch method of a window interface is adapted to control an object in the window interface. The method includes providing a first optical sensing window to obtain a first tracking signal and providing a second optical sensing window to obtain a second tracking signal; resolving the first tracking signal to determine a first displacement direction and resolving the second tracking signal to determine a second displacement direction; and controlling a motion of the object in the window interface according to a relative relation between the first displacement direction and the second displacement direction.
