While desktops and smartphones have established user interface standards, they are still lacking for virtual and augmented reality devices. Hands-free interaction for these devices is desirable. This paper explores utilizing eye and head tracking for interaction be yond buttons, in particular, selection in scroll lists. We conducted a user study with three diferent interaction methods based on eye and head movements, gaze-based dwell-time, gaze-head of set, and gaze-based head gestures and compared them with the state-of-the-art hand-based interaction. The study evaluation of quantitative and qualitative measurement provides insights into the trade-of between physical and mental demands for augmented reality interfaces.
