“Level-Ups” are computer-controlled stilts that allow virtual reality users to experience elevation in real-walking environment. Each Level-Up unit is a self-contained device worn like a boot. Its main functional element is a vertical actuation mechanism, so called lift-table.

Level-Ups are operated in a typical VR environment. In the below picture Sven is wearing an Oculus Rift and a MacBook on his chest, where the actual VR processing is running. To find out where the user is in the virtual world, we used a motion capture system, in this case Optitrack.
