A motion tracking system enables faithful capture of subtle facial and eye
motion using a surface electromyography (EMG) detection method to detect
muscle movements and an electrooculogram (EOG) detection method to detect
eye movements. An embodiment of the motion tracking animation system
comprises a plurality of pairs of EOG electrodes adapted to be affixed to
the skin surface of the performer at locations adjacent to the
performer's eyes. The EOG data comprises electrical signals corresponding
to eye movements of a performer during a performance. Programming
instructions further provide processing of the EOG data and mapping of
processed EOG data onto an animated character. As a result, the animated
character will exhibit he same muscle and eye movements as the performer.
