Abstract
Line of sight detecting apparatus such as an oculometer produces signals indicative of the direction along which an operator is looking. A display with predetermined positions thereon is positioned for viewing by the operator. A computer receives the signals from the line of sight detecting apparatus and utilizing a timing function determines when the operator's line of sight is directed toward one of the predetermined positions on the display for a predetermined length of time. Depending upon which of the predetermined positions is viewed by the operator for the predetermined time period, the computer produces a signal which is used to produce various images, such as indicator readings, or to produce various control functions for the operator.
