In this paper we introduce a novel approach for smooth pursuitseye movement detection and demonstrate that it allows up to 160targets to be distinguished. With this work we advance the well-established smooth pursuits technique, which allows gaze interac-tion without calibration. The approach is valuable for researchersand practitioners, since it enables novel user interfaces and appli-cations to be created that employ a large number of targets, forexample, a pursuits-based keyboard or a smart home where manydifferent objects can be controlled using gaze. We present findingsfrom two studies. In particular, we compare our novel detectionalgorithm based on linear regression with the correlation method.We quantify its accuracy for around 20 targets on a single circleand up to 160 targets on multiple circles. Finally, we implemented apursuits-based keyboard app with 108 targets as proof-of-concept    «
