1. A motion sensing input device of a computer system, comprising:

  • a motion sensor, including a micro-control unit, a wireless transmitting unit, and two gyroscopes, for sensing changes of angular velocities around two axes of the motion sensor via the two gyroscopes, respectively, generating sensed data via the micro-control unit, and transferring the sensed data wirelessly via the wireless transmitting unit; and

    a receiver, connected with the computer system and including a microprocessor, a wireless receiving unit, and a transmission interface, for receiving the sensed data via the wireless receiving unit, converting the sensed data to a corresponding keyboard input signal via the microprocessor, and transmitting the keyboard input signal to the computer system via the transmission interface.
