Pointing input device
First Claim
1. A pointing input device, for controlling a cursor position of an image processing device, and the pointing input device comprising:
- an inertia device, having a gyroscope and an accelerometer, for detecting a movement of a user'"'"'s hand while generating an electronic signal;
a signal processor, electrically coupled to the inertia device, for retrieving electronic signal of the inertia device and processing and converting the electronic signal into a cursor position signal; and
a wireless transmitter, electrically coupled to the signal processor, for retrieving the cursor position signal of the signal processor, and transmitting the cursor position signal to the image processing device having a receiving device.

Abstract
This invention discloses a pointing input device for controlling a cursor position of an image processing device, and the pointing input device comprises an inertia device, a signal processor and a wireless transmitter, wherein the inertia device has a gyroscope and an accelerometer. The input device is reduced to a handheldable size, and it can self detect the posture of a user'"'"'s hand at the time, and achieve the purpose of controlling a cursor by an instinctive pointing behavior, and allows users to operate at an ergonomic operating mode and lowers the manufacturing cost of the input device.
