Abstract: 

THE GOAL OF HUMAN-COMPUTER INTERFACE (HCI)) (HUMAN-ROBOT INTERFACE HRI) RESEARCH IS TO PROVIDE HUMANS WITH A NEW COMMUNICATION CHANNEL THAT ALLOWS TRANSLATING HUMAN'S WILL STATES VIA A COMPUTER INTO APPLICATION SPECIFIC ACTIONS. THIS PAPER PRESENTS A NOVEL HANDS-FREE CONTROL SYSTEM FOR CONTROLLING A VIRTUAL WHEELCHAIR, WHICH IS BASED ON FOREHEAD MULTI-CHANNELS BIO-SIGNALS AS EMG (ELECTROMYOGRAM) SIGNALS. IN THIS METHOD, NEW LOCATIONS FOR THREE BI-POLAR ELECTRODES ARE SELECTED. THE BIOELECTRIC SIGNALS ARE PICKED UP FROM LATERAL SIDES AND CENTRE OF FOREHEAD THEN THE BIO-SIGNALS ARE PASSED THROUGH A BAND PASS FILTERS. MOTION CONTROL COMMANDS (FORWARD, LEFT, RIGHT, BACKWARD AND STOP) ARE CLASSIFIED BY SVM METHOD. THESE COMMANDS ARE USED FOR CONTROLLING THE VIRTUAL WHEELCHAIR BY INTERFACE SOFTWARE IN A PERSONAL COMPUTER.
