Abstract

The invention relates to a handheld pointing device, a pointing method thereof and a method for improving static migration. The handheld pointing device comprises a first quartz piezoelectric gyro, a second quartz piezoelectric gyro and a processing unit, wherein the processing unit is coupled with the first quartz piezoelectric gyro and the second quartz piezoelectric gyro respectively. The quartz piezoelectric gyros are used for detecting the rotation of the handheld pointing device and generating a first rotation output and a second rotation output, and the processing unit is used for generating pointing signals according to the first rotation output and the second rotation output.

Description

technical field [0001] The present invention relates to a hand-held pointing device, in particular to a hand-held pointing device and a pointing method thereof. Background technique [0002] In the past, the pointing device of the image processing device, such as a computer mouse, must be placed on an auxiliary plane (such as a desktop) and must be connected to the computer with a cable, which limits the user to use it at a fixed place. , it is more difficult to achieve the purpose of controlling the cursor position through intuitive pointing behavior. [0003] In recent years, hand-held pointing devices have been gradually developed, allowing users to control the movement of the cursor on the computer screen without being restricted to use the pointing device at a fixed location. However, most of the sensors are two accelerometers or a combination of an accelerometer and a mechanical gyroscope or a capacitive sensing MEMS gyroscope or a fiber optic gyroscope. [0004] For...
