GlassGaze is an android app designed for Google Glass that allows the Google Glass to know where exactly the user is looking at. The user can interact with the head-mounted display through eye movements. With GlassGaze, the Google Glass not only knows where on the display you are looking at but also knows where you are looking in your field view. GlassGaze is actually a client for the Haytham gaze tracker. Both the Haytham gaze tracker and the GlassGaze client are released as freeware and open-source. By attaching a small camera to the Google Glass frame to capture the eye image the the remote computer is able to calculate the gaze coordinates and send it back to the Glass through Wifi. The need for a remote computer for image processing is due to the limitations of processing and battery resources on the Google Glass.
