Eye and Gaze Tracking in visage|SDK™ is available as part of Facial Features Tracking, one of the default configurations visage|SDK™ FaceTrack, the powerful head and facial features tracking engine developed by Visage Technologies.
FaceTrack provides real-time gaze direction, as well as 3D and 2D coordinates of the eyes (pupils). Information is delivered through an easy-to-use API allowing to easily integrate the eye and gaze tracking technology into any application. Eye and gaze tracking is fully automatic.
Furthermore, if a simple calibration is performed prior to a tracking session, results are available in form of screen-space gaze point, particularly useful for marketing research, user studies and other applications that benefit from knowing where (approximately) on the screen the user is looking. For an in-browser demonstration using HTML5 technology, please see our gaze tracker demo.
