Disney has unveiled the HoloTile floor, a multi-person, omni-directional, modular, and expandable treadmill floor that allows people to have a shared virtual reality experience and walk in any direction without colliding or walking off its surface. The floor is made up of tiles that work together to keep people or objects in the center. The technology has potential applications in virtual reality, theatrical stages, and other areas. However, its development and implementation are still in the early stages.
