We describe here a pilot user study comparing five different locomotion interfaces for virtual reality (VR) locomotion. We compared a standard non-motion cueing interface, Joystick, with four leaning-based seated motion-cueing interfaces: NaviChair, MuvMan, Head-Directed and Swivel Chair. The aim of this mixed methods study was to investigate the usability and user experience of each interface, in order to better understand relevant factors and guide the design of future ground-based VR locomotion interfaces. We asked participants to give talk-aloud feedback and simultaneously recorded their responses while they were performing a search task in VR. Afterwards, participants completed an online questionnaire. Although the Joystick was rated as more comfortable and precise than the other interfaces, the leaning-based interfaces showed a trend to provide more enjoyment and a greater sense of self-motion. There were also potential issues of using velocity-control for rotations in leaning-based interfaces when using HMDs instead of stationary displays. Developers need to focus on improving the controllability and perceived safety of these seated motion cueing interfaces.
