Abstract

An input device for a computer is provided. The input device includes a motion detector and a receiver. The motion detector has an inertia sensor, a gyro, an optical mouse module, and a microprocessor. When the motion detector is in a motion operation mode, the inertia sensor and the gyro are enabled for detecting a motion state and direction of the motion detector in a 3-D space, so as to generate an inertia data and a direction data. When the motion detector is in a mouse operation mode, the optical mouse module is enabled for detecting a motion stat of the motion detector on a 2-D plane, so as to generate a coordinate data. The microprocessor codes the coordinate data or codes the inertia data and the direction data to generate a detecting data for the receiver. Then, the detecting data is transmitted to the computer for operating the computer.
