Abstract
This invention discloses a capacitive stylus including a pen housing and an eraser for being applied to a touch device. The pen housing includes a tip for emitting an input signal, and the eraser can emit an erasing signal to the touch device. The intensity or erasing range of the erasing signal is determined by the pressure that the eraser exerted on the touch device. In addition, the eraser can trigger a signal to instruct the touch device performing an application.
