Abstract
A touch device including a touch screen, a first input device and a processor is provided. At a first start time, when the first input device touches on the touch screen with a first touch area at a first position, the touch screen generates a first event, and the first input device transmits a first signal to the touch screen. The processor is coupled to the touch screen. When the touch screen receives the first signal during a pre-determined period from the first start time and the first touch area is larger than a first area threshold, the processor determines that the first event belongs to the first input device and that the first position is a start position of the first input device.
