This makes the pupil much more distinguishable and, thus, easier to track. The diy glasses we designed use near-infrared leds to illuminate the eye and create a dark pupil effect. The pupil tracking relies upon a clear and dark image of the pupil. Note that we use the GSL (gnu scientific library) for calibration, which is GPL, thus the eye tracking source code is GPL. The eye-tracking software detects and tracks the position of a pupil from an incoming camera or video image, and uses a calibration sequence to map the tracked eye/pupil coordinates to positions on a computer screen or projection. Documentation, setup guides and more information can be found at. In order to compile and develop the EyeWriter source code, you will need to download openframeworks (pre release v0.06). The software for both parts has been developed using openframeworks, a cross platform c++ library for creative development. The source code for the project is currently being hosted at. The EyeWriter software is two parts - an eye-tracking software designed for use with our low-cost glasses, and a drawing software designed for drawing with eye movements.
