The ability to determine the motion of an observer and his/her point of regard (POR) in the world can be very beneficial to the study of human visual behavior and cognition. State-of-the-art eye-tracking systems output an observer's POR in 2D image or screen coordinates. Here we present a novel technique for determining POR in 3D world coordinates using a monocular video-based eye tracker. Currently, there are various techniques to determine an observer's gaze within an image sequence but many fewer techniques for determining his/her POR in three dimensions. Existing eye-tracking methods for determining a subject's 3D POR are limited to virtualreality applications and/or can only be used with binocular eye trackers. Techniques that provide 3D information in the real world are limited to gaze direction without precise report on POR.
