Real-time eye gaze and head pose estimation


C/C++ project for Windows and Linux; uses a plain web camera, mounted on top of the user's screen and produces 2D (yaw/pitch) vectors for the user's eye gaze and head pose (including roll). Results can be used to model the user's attention or interest.

The software has been used in the framework of the Feelix Growing project (, as well as in FP6 IP Callas (emotion in arts and entertainment), FP6 STREP AgentDysl (reading assistance for dyslexic children) and FP7 IP Metabo (car driver assistance)
