Most current virtual reality (VR) applications use some form of teleportation to cover large distances, or real walking in room-scale setups for moving in virtual environments (VEs). Though real walking is the most natural for medium distances, it gets physically demanding and inefficient after prolonged use, while the sudden viewpoint changes experienced with teleportation often lead to disorientation. To close the gap between travel over long and short distances, we introduce a biomechanically-inspired locomotion user interface (LUI) for immersive pseudo-realistic walking. The idea is to map the human’s embodied ability for walking to a finger-based locomotion technique. Using the triggers of common VR controllers, the user can generate near-realistic virtual bipedal steps. We analyzed head oscillations of VR users while they walked with a head-mounted display, and used the data in our biomechanically-inspired LUI to generate pseudo-realistic walking with respect to the trigger pulls. Next we evaluated how the simulation of walking biomechanics using our fingerbased LUI affect task performance and spatial cognition. The results show that users can efficiently use our biomechanicallyinspired LUI, while still benefiting from the inherent advantages of real walking.
