Gaze and Foot Input
Vijay Rajanna · 2016
Transforming gaze input into a rich and assistive interaction modality is one of the primary interests in eye tracking research. Gaze input in conjunction with traditional solutions to the "Midas Touch" problem, dwell time or a blink, is not matured enough to be widely adopted. In this regard, we present our preliminary work, a framework that achieves precise "point and click" interactions in a desktop environment through combining the gaze and foot interaction modalities. The framework comprises of an eye tracker and a foot-operated quasi-mouse that is wearable. The system evaluation shows that our gaze and foot interaction framework performs as good as a mouse (time and precision) in the majority of tasks. Furthermore, this dissertation work focuses on the goal of realizing gaze-assisted interaction as a primary interaction modality to substitute conventional mouse and keyboard-based interaction methods. In addition, we consider some of the challenges that need to be addressed, and also present the possible solutions toward achieving our goal.
