Desktop access with non-verbal sound input

Most motor-handicapped computer users who cannot use their hands and arms rely on expensive or complicated alternative input devices to operate computers. In this paper, we proposed a sound-based input scheme that helps users perform tasks regularly found on Windows operating systems. Non-verbal sounds, including humming and fricative sounds, are used in cooperation with menus in multiple modes as the replacement of the use of computer mice and keyboards. Our evaluation has suggested that the implementation of our proposed scheme is accurate and responds promptly. Still, further improvements on facilitating users to select the most appropriate modes for desired tasks should improve the overall performance of the users accomplishing those tasks.
