An EMG-based Mouse Controller for A Tetraplegic

We propose an EMG-based mouse control method for helping the tetraplegic use computer by teeth-clenching. In this paper, we investigate useful actions and muscles as a means of the input method for the tetraplegic and a method of processing EMG signals for the purpose of controlling mouse control from the recognized patterns. Also, we developed a prototype system for acquiring and processing such EMGs based upon the specifications obtained from the study. Our experimental result shows that the proposed method shows promise of controlling the position of a mouse pointer and clicking mouse buttons in an operating system. In fact, our prototype system offers a great deal of convenience in wearing the prototype on a user´s forehead. We verified our result by comparing the performance of the proposed system to that of a conventional mouse
