Abstract
An improved communications device for use by handicapped persons utilizes a list of elements such as the alphabet. The list is sequentially scanned in a forward direction at a speed faster than the response time of the individual. Upon a first operation of a switch, the scan reverses direction and presents the elements at a slower speed. A second switch operation by the user indicates the selection of the desired element. Display and interpretation of the selected element is made in whatever manner desired, and the scanning process is repeated to enable selection of the next element.
