Extending the visual field of a head-mounted eye tracker for pervasive eye-based interaction

Research output: Contribution to book/anthology/report/proceedingArticle in proceedingsResearchpeer-review


Pervasive eye-based interaction refers to the vision of eye-based interaction becoming ubiquitously usable in everyday life, e. g. across multiple displays in the environment. While current head-mounted eye trackers work well for interaction with displays at similar distances, the scene camera often fails to cover both remote and close proximity displays, e. g. a public display on a wall and a handheld portable device. In this paper we describe an approach that allows for robust detection and gaze mapping across multiple such displays. Our approach uses an additional scene camera to extend the viewing and gaze mapping area of the eye tracker and automatically switches between both cameras depending on the display in view. Results from a pilot study show that our system achieves a similar gaze estimation accuracy to a single-camera system while at the same time increasing usability.
