CyberWalk is an omni-directional platform that adjusts its speed and direction to allow for unlimited exploration of a virtual space. It’s the love child of a consortium of German, Italian, and Swiss labs that’s able to detect when and how quickly a user is changing direction. By precisely monitoring the position of the user on the platform using a Vicon motion-capture system, the controller computes estimates for the two variables and tries to adjust the speeds of the linear belts.”]
