Towards pervasive eye tracking

The human gaze provides paramount cues for communication and interaction. Following this insight, gaze-based interfaces have been proposed for human computer interaction (HCI) since the early 90s, with some believing that such interfaces will revolutionize the way we interact with our devices. Since then gaze-based HCI in stationary scenarios (e. g., desktop computing) has been rapidly maturing, and the production costs of mainstream eye trackers have been steadily decreasing. In consequence, a variety of newapplicationswith the ambitious goal to apply eye tracking to dynamic, real-worldHCI tasks and scenarios haveemerged. This article gives an overview of the research conducted by the Perception Engineering Group at the University of Tübingen.
