摘　　要：为了解决手部残疾人无法正常操作电脑鼠标这一实际困难,本文基于肌电信号采集模块MYO和STM32微控制器,设计了一款可穿戴的肌电控制鼠标。由置于上臂的MYO模块、陀螺仪、STM32模块、蓝牙组成。其中,MYO模块用来实时采集使用者的肌电信号,并进行信号模拟调制;STM32进行信号AD转换、特征分析,解析出手臂用力模式;陀螺仪发送手臂实时移动位置信息来控制光标移动;蓝牙模块实时发送手臂用力模式及光标移动信息给上位机,从而控制上位机光标的点击、拖动、移动动作。该鼠标具有功耗低、体积小、无线传输、信号精度高、控制灵敏度高、稳定可靠等优势,可以很好地解决手部残疾人操作和控制电脑鼠标问题。In order to solve the problem that the hand of disabled people can＇t operate the computer mouse normally,a wearable myoelectric control mouse based on the myoelectric signal acquisition module MYO and STM32 microcontrollers is designed in this paper. It consists of the MYO module,a gyroscope,STM32 module,and Bluetooth placed on the upper arm. Among them,the MYO module is used to collect the user＇s EMG signal in real-time and it＇s signal analog modulation is performed;signal AD conversion and feature analysis are performed by STM32 and the arm force mode is analyzed. The cursor movement is controlled by the position information of the arm sent by the gyroscope real-times. The arm force mode and cursor movement information are sent by Bluetooth in real-time to the host computer to control the clicking,dragging and moving actions of the host computer cursor. The mouse has the advantages of low power consumption, small size, wireless transmission, high signal accuracy, high control sensitivity, stability and reliability and is capable to solve the problem of hand-handicapped manipulating and controlling the computer mouse.
