1. An angle sensor-based pointer comprising:
- an angle sensor detecting rotation angles of hand movements in at least two directions and producing voltage signals in response to the rotation angles;
a signal processing unit connected to the angle sensor, receiving the voltage signals and processing the voltage signals to a coordinate signal for moving a cursor from an original position to a new position; and
a wireless transmitting unit connected to the signal processing unit, receiving the coordinate signal from the signal processing unit and transmitting the coordinate signal wirelessly to a target device.

Abstract
An angle sensor-based pointer has an angle sensor, a signal processing unit and a wireless transmitting unit. The angle sensor detects rotation angles of hand movements in at least two directions and accordingly produces voltage signals in response to the rotation angles. The voltage signals are further input to the signal processing unit and transformed to a coordinate signal. The coordinate signal is modulated and transmitted wirelessly through the wireless transmitting unit to a target device for moving a cursor from an original position to a new position.
