NON-INTRUSIVE GAZE TRACKING FOR HUMAN-COMPUTER INTERACTION

Andrew Gee and Roberto Cipolla

May 1994

Current approaches to gaze tracking tend to be highly intrusive: the subject must either remain perfectly still, or wear cumbersome headgear to maintain a constant separation between the sensor and the eye. This paper describes a more flexible vision-based approach, which can estimate the direction of gaze from a single, monocular view of a face. The technique makes minimal assumptions about the structure of the face, requires very few image measurements, and produces a useful estimate of the facial orientation. The computational requirements are insignificant, so with automatic tracking of a few facial features it is possible to produce real-time gaze estimates. A robust, multiple hypothesis tracker is described, which utilises no expensive correlation operations and runs at video rate on standard hardware.

Keywords: Gaze tracking, human-computer interaction, weak perspective, affine camera, real-time feature tracking.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
