Multi-purpose mouse capable of locating through spatial absolute position

Abstract

The invention provides a multi-purpose mouse capable of locating through a spatial absolute position. A multi-purpose mouse body comprises the six parts; sensing chips MPU6050 (1) and (2) are respectively composed of a three-axis acceleration sensor and a three-axis gyro; a three-axis magnetic field meter RMG144 (3) is provided; the two sensing chips send the sensed acceleration and acceleration and magnetic field strength of each axis to a a main processor (4) through an I2C bus; the (4) performs initial calculation for the posture to determine an absolute spatial coordinate system, calculates the posture and distinguishes an action signal and finally outputs the absolute position of the current space, a button to be controlled and the function to a wireless emitting module (6); a power module (5) supplies power to the whole system; a wireless receiving module (7) of the receiving part is used for receiving and decoding; a interface module (8) processes data into the general variable of the mouse in a USB device and then sends to the system.

Description

technical field [0001] The present invention The present invention relates to a space mouse used for computers and households, in particular to a multi-purpose mouse positioned by space absolute position. Background technique [0002] There are many spatial mice on the market at this stage, but many of them have single functions and simple control systems. They often only have two-axis acceleration sensing devices, which can only recognize the simplest X-Y direction movement. Moreover, there are a large number of systematic errors and inadaptability to spatial changes. The present invention establishes the absolute position of the space through the unprecedented use of nine-dimensional data. It can fully display the trajectory of the mouse in the air, intelligently judge according to the trajectory, and then output the appropriate X-Y direction, wheel operation, left and right button functions, etc. High recognition accuracy and strong anti-interference ability. It also h...

[0002] There are many space mice on the market at this stage, but many of them have single functions and simple control systems. They often only have two-axis acceleration sensing devices, which can only recognize the simplest X-Y direction movement.

Moreover, there are still a large number of systematic errors, and the inability to adapt to changes in space
