Disney is Working on a VR Treadmill That Supports Multiple Users
Disney has unveiled an omni-directional treadmill called HoloTile, which aims to provide users with a realistic walking experience in virtual reality. The treadmill is made up of rotating and pitch-changing tiles that can simulate walking in any direction. Disney claims that HoloTile is the world's first multi-person, omni-directional, modular, expandable treadmill floor, allowing multiple users to have a shared VR experience without colliding or walking off the surface. The project is currently led by Lanny Smoot, a Disney Research Fellow, and the prototype version is showcased in a new video. The HoloTile could also be used in theatrical stages. Though there have been previous omni-directional treadmills, they have been expensive and complex. Disney's HoloTile may be featured in the company's theme parks in the future.
