Abstract


As we know, it is very difficult for the upper limb disabled people to operate mouse. Thissubject designs a special mouse for them. The control source of this system is the surface EMGof temporalis muscles. Using control sources, a variety of mouse actions can be achieved.The design of this system consists of the following four aspects.1. The design of myoelectricity acquisition analog circuit and its power circuit.2. Using microcontroller, analog signals are converted to digital signals. Then a digitalfiltering process is executed.3. The wireless module will transmit the collected SEMG signal to Windows programs.4. SEMG waveform can be displayed in real time. The duty of C#program is to achievethis function. Users can train their own SEMG through the observation of theirwaveform. After that, a precise threshold value can be set up. Finally, mouse actionswill be controlled by another Windows program.
