 Build glasses that record two video streams  Transfer the streams to an eye-tracking application hosted in an Android device  Process the information to measure the point of gaze

 Based on: Building a lightweight Eyetracking Headgear Jason S. Babcock & Jeff B. Pelz Rochester Institute of Technology  A04_babcock_pelz_color_small.pdf

 Uses an infrared (IR) source to illuminate the eye  Obtains a frame of reference by using the scene camera  Monitors the eye by employing a small camera

 Obtains a reference for calibration using a laser diode and a 2D diffraction grating  Uses the scene camera to capture the 9-point grid
