  Eye-tracking is an increasingly popular technique in which user’s eye movements are captured by a computer system, allowing it to ascertain where the user is looking in a display or visual scene (fixations), and the sequence in which these fixations take place. But while increasingly popular, eye-tracking solutions are still considerably invasive and cumbersome, and especially limiting when used outdoors in a wearable form factor during long periods of time. This ultimately limits their adoption in areas such as virtual- and augmented-reality, or during interaction with portable devices such as smart phones and watches, and tablet computers. The techniques currently available present a trade-off between precision and invasiveness, with the scleral contact lens being the most precise but also more the most invasive eye-tracking approach. This project fits into this body of work by aiming to explore arguably the least invasive eye-tracking approach to date: the tracking of user’s gaze through a pair of in-ear-phones.
