Abstract
This paper introduces a novel technique for touchless typing with head movements allowing to reach any alphabet character in only three steps. Head movements are frequently used for human-computer interaction by users with motor impairments unable to operate standard computer input devices. In such interfaces great difficulty is typing. Many directional head movements are required to reach subsequent characters using the on-screen keyboard and additional mechanism (like eye blink or mouth open) supplements the selection process. In this paper, a reduced interaction keyboard for touchless typing with head movements is proposed. The solution is based on recognition of head movements in four main directions.
