Current approaches for locomotion in virtual reality are either creating a visual-vestibular conflict, which is assumed to cause simulator sickness, or use metaphors such as teleportation to travel longer distances, lacking the perception of self motion. We propose VRSpinning, a seated locomotion approach based around stimulating the user's vestibular system using a rotational impulse to induce the perception of linear self-motion. In a first study we explored the approach of oscillating the chair in different frequencies during visual forward motion and collected user preferences on applying these feedback types. In a second user study we used short bursts of rotational acceleration to match the visual forward acceleration. We found that this rotational stimulus significantly reduced simulator sickness and increased the perception of self-motion in comparison to no physical motion.
