Computer vision based interface to virtual reality / Computer vision baseret interface til virtual reality

The current interfaces in the VR-Media Lab's CAVE is based on physical devices with long wires. These wires are often disturbing for the user and, thus, reduce the immersiveness. In this effort it has been investigated how computer vision can be applied to create interfaces providing the same performance as the wired devices. The approach is based on four infrared cameras tracking markers attached to the user's VR-glasses and interface device, respectively, in order to estimate the user's viewing direction and interface position. This way of interaction is wireless and by that less disturbing for immersiveness. A tracking method has been developed and implemented that performs robustly with low latencies and update rates up to 200Hz. Partly funded by ARTHUR and VR-Media Lab.
