Patent Images
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.

Abstract
A motion sensing input device of a computer system includes a motion sensor and a receiver. The motion sensor has two gyroscopes for sensing motions in different directions when a user operates the motion sensor. The motion signals are wirelessly transmitted to the receiver connected with the computer system. Furthermore, the motion signals are directly decoded via the receiver, and then they are converted to keyboard input signals. When the user plays a computer game by using the motion sensor to replace a keyboard, the user can experience a lifelike game environment and an intuitive operation mode.
