Abstract
The present disclosure discloses the wireless virtual mouse. The wireless virtual mouse comprises a head-mounted device and a wireless virtual mouse body. The wireless virtual mouse body comprises a head motion detection module, an eyelid blinking detection module, a communication module, and a power supply module. The head motion detection module collects relative changes of head position through an aerial attitude sensor. A wireless transceiver of the communication module sends signals generated based upon the relative changes of the head position to a computer, and a cursor on a screen of the computer changes synchronously based upon the signals. The eyelid blinking detection module collects a movement distance and a movement duration of an eyelid through a photoelectric motion sensor, and the wireless transceiver sends change signals generated based upon the movement distance and the movement duration to the computer.
