Augmented and Virtual Reality
Multiple virtual reality (VR) head-mounted displays (HMDs) are utilized in the laboratory for various research purposes, such as mocking-up spaceflight habitats and performing operational tasks similar to those we expect astronauts to face. Some of the HMDs include Oculus 91ÃÛÌÒ¸ó (Rift DK2 and Quest) and HTC Vive (gen 1, Vive 2, and Vive 2 Pro Eye). Other equipment which interfaces with VR includes the omni-directional treadmill (KAT VR) and Roto Chair. The KAT VR is a stationary treadmill which allows individuals to move around in VR environments while staying securely in place. This prevents the user from losing their balance or hitting physical hazards while exploring a virtual environment. The Roto VR Chair rotates along the yaw axis, allowing a person to match their angular position being observed in VR. We have used this chair previously to induce vestibulo-ocular illusions. The Microsoft Hololens is also used for research ulizing augmented reality.
