In their own words
OpenGazer
OpenGazer is a Linux application that uses an ordinary webcam to estimate gaze direction and send it to other programs. It also tracks head position and rotation, and displays the estimated gaze point, head-rotation lines, and calibration target. Setup calls for a camera at 640×480, placed centrally below the monitor. Users calibrate by looking at indicated screen points while keeping their head still, then choose facial tracking points; the project calls for at least four and recommends seven or eight. Gaze estimates appear on screen, print to standard output, and are sent through a local UDP socket on port 20230. Dasher is an example of software that can use the gaze direction for writing with the eyes. OpenGazer is free under GPLv2 and uses the X Window System interface. It is marked Alpha, with a last update listed as 2013-04-24. Building it requires VXL, OpenCV, gtkmm, cairomm, and Boost.
