Abstract

Described is a controlled point of regard tracking device implementation that provides an eye contact user interface to visual operating systems, such as computer workstations. The implementation is an improvement over previous devices which use eye tracker (ET) devices since the point of regard tracking is controlled entirely by the operator.

Point of Regard Tracking Device

       Described is a controlled point of regard tracking device
implementation that provides an eye contact user interface to visual
operating systems, such as computer workstations. The implementation
is an improvement over previous devices which use eye tracker (ET)
devices since the point of regard tracking is controlled entirely by
the operator.

      In prior art, the use of an ET device to control the movement
of point of regard tracking was operational during the entire
functional implementation.  This caused considerable difficulty in
the ability to control the tracking since the instructions to the ET
device were operational when not required.  The concept described
herein implements an operator control so that the tracking
implementation will only occur at the discretion of the operator.

      Fig. 1 shows a typical implementation of an ET device to
control the cursor location on a visual display screen, as used in
computer workstations.  When the operator makes the decision to move
the cursor from one location on the screen to another, contact is
made from the operator's eye to the remote oculometer by means of an
infrared (IR) beam. At the same time, the operator presses the clutch
button located on the keyboard.  The clutch button actuates a circuit
which allows the cursor to move in accordance with the eye movement
of the operator.  The operator need only look at the location that
the cursor should be moved...
