ABSTRACT:
An apparatus and method for selecting and outputting characters by making a teeth clenching motion for disabled person are disclosed. The apparatus includes: an electromyogram signal obtaining unit including electromyogram sensors disposed at both sides for generating an electromyogram signal according to a predetermined muscle activated when a disabled person clenches teeth, and a ground electrode connected to a body of the disabled persons for providing a reference voltage; and an electromyogram signal processing unit for outputting a character by identifying a teeth clenching motion pattern of each block according to a side of teeth clenched, a duration of clenching teeth and consecutive clenching motions through analyzing the obtained electromyogram and selecting characters according to the identified teeth clenching motion pattern.
