Your eyes explain everything: exploring the use of eye tracking to provide explanations on-the-fly

Journal Contribution - Journal Article Conference Contribution

Despite the proven advantages, explanations are not yet mainstream in industry applications of recommender systems. One of the possible reasons for this lack of adaption is the risk of overwhelming end-users with the explanations. In this paper, we investigate whether it is possible to overcome the information overload problem by only showing explanations that are relevant to the user. To do so, we leverage the gaze of a user as a novel responsiveness technique. We first conducted a co-design session to discuss several design decisions of a gaze responsive music recommender interface. As a next step, we implemented a gaze responsive music recommender interface and compared it in a between-subject user study (N=46) to two interfaces with more classical responsive techniques: a hover responsive interface and a click responsive interface. Our results show that providing explanations based on gaze is a promising solution to provide explanations on-the-fly.
