Abstract
The disclosure discloses a stylus and a human-machine interactive apparatus. The stylus includes: a body, including a refill, a housing and a clamping piece; wherein the refill can perform a lever deflection motion by taking the clamping piece as a pivot when it is under a pressure; a light emitter, fixed at an end portion of the refill and has a light emitting surface facing away from the refill; a light signal sensing element on a side of the end portion of the refill and configured to sense a light beam emitted by the light emitter and to output coordinate information of a position irradiated by the light beam; and a micro control unit configured to generate a corresponding drive signal according to the coordinate information output by the light signal sensing element and to send the drive signal to a touch screen via the refill.
