The record

Purpose: OpenGazer uses an ordinary webcam to track gaze direction and pass it to other programs.
Use case: The project gives Dasher as an example of software that can use OpenGazer so a person can write with their eyes.
Approach: The project describes itself as a low-cost software alternative to commercial hardware-based eye trackers.
License: OpenGazer is distributed under the GNU General Public License version 2.0 (GPLv2).
Platform: SourceForge lists Linux as the operating system and X Window System (X11) as the user interface.
Development status: SourceForge lists the project status as Alpha and its last update as 2013-04-24.
Build requirements: The repository README lists VXL, OpenCV, gtkmm, cairomm, and Boost as build requirements.
Camera setup: The README instructs users to set the camera to 640×480 and place it centrally below the monitor.
Calibration: The README says users calibrate by looking at indicated screen points while keeping their head still.
Tracking setup: The README instructs users to select at least four facial tracking points and recommends seven or eight.
Output: The README says gaze estimates are printed to standard output and sent over a local UDP socket on port 20230.
Custom use: The README says changing calibration points to two points can make OpenGazer work as a binary switch.
Gaze output: The program estimates the gaze point and displays it on screen.
Head tracking: Users select facial points to track head position and rotation alongside gaze.
