GitHub describes it as Javascript library for headtracking via webcam and WebRTC/getUserMedia. The repository metadata lists JavaScript as its primary language. The README describes the project this way: headtrackr is a javascript library for real-time face tracking and head tracking , tracking the position of a users head in relation to the computer screen, via a web camera and the webRTC/getUserMedia standard.

The README section "README details" states: For a demonstration see this video or try out some of the examples with a laptop that has a camera and a browser that has camera webRTC/getUserMedia support. For an overview of browsers supporting the getUserMedia standard see http://caniuse.com/stream.

The README section "Usage" states: The following code initiates the headtrackr with a video element which will be used for the mediastream, and a canvas element we will copy the videoframes to.

The README section "Usage" states: When the headtracker is started, this will now regularly generate the events headtrackingEvent and facetrackingEvent on the document. The event headtrackingEvent has the attributes x , y , z , which tells us the estimated position of the users head in relation to the center of the screen, in centimeters. The event facetrackingEvent has the attributes x , y , width , height and angle , which tell us the estimated position and size of the face on the video.
