Gaze-based interaction with public displays using off-the-shelf components

Eye gaze can be used to interact with high-density information presented on large displays. We have built a system employing off-the-shelf hardware components and open-source gaze tracking software that enables users to interact with an interface displayed on a 55” screen using their eye movements. The system works at a viewing distance of 1 to 1.5 meters and requires a 30 second calibration procedure for every user. We demonstrate how it can be used to navigate a digital bulletin board display with several notes on top of each other. There are some technical challenges detecting the eyes when people are wearing glasses and when external light sources are present.
