【摘要】：针对上肢残障人操作电脑鼠标不便的现状，本课题为该类人群设计了一款上肢残障人专用鼠标系统。该系统使用咬牙动作时头部两侧颞肌表面肌电信号作为控制源，控制鼠标产生各种动作。本系统设计主要由以下四方面内容组成： 1、设计颞肌表面肌电采集模拟电路及其供电电路。 2、利用微控制器对采集得到模拟肌电信号进行数字化处理并数字滤波。 3、由无线收发模块将下位采集得到的肌电数据传送给上位Windows程序。 4、上位C#程序负责实时显示颞肌表面肌电波形。使用者先通过观察波形训练自己肌电信号满足控制要求，然后因人而异的设置阈值参数，，最后控制鼠标产生各种动作。
[Abstract]:Aiming at the inconvenient operation of the computer mouse in the upper limb disabled people, a special mouse system for the upper limb disabled people is designed in this paper. The system uses the EMG signal on the surface of the temporal muscle on both sides of the head as the control source during the bite movement. Control the mouse to produce a variety of actions. The system design is mainly composed of the following four aspects:. 1. The simulation circuit and the power supply circuit of the temporal muscle surface electromyography were designed. 2. Digital processing and digital filtering of acquired analog EMG signal by microcontroller. 3. By wireless transceiver module, the acquired EMG data is transmitted to the upper Windows program. 4. The upper C # program is responsible for real-time displaying the surface myoelectric wave shape of the temporal muscle. The user first trains his EMG signal to meet the control requirements by observing the waveform, then sets threshold parameters according to the individual, and finally controls the mouse to produce various actions.
