Abstract
Locomotion-based motion sickness has long been a complaint amongst virtual reality gamers and drone pilots. Traditional head-mounted display experiences require a handheld controller (e.g. thumb stick, touchpad, gamepad, keyboard, etc.) for locomotion. Teleportation compromises immersive presence and smooth navigation leads to sensory imbalances that can cause dizziness and nausea (even when using room-scale sensor systems). Designers have therefore had to choose between comfort and immersion. The invention is a hands-free, body-based navigation technology that puts the participant's body in direct control of movement through virtual space. Participants lean forward to advance in space; lean back to reverse; tip left or right to strafe/sidestep; and rotate to look around. In some embodiments, the more a participant leans, the faster they go. Because the interactions were designed to respond to natural bearing and balancing instincts, movement coordination is intuitive and vection-based cybersickness is reduced.
