The Radboud Immersive Virtual Environment Research (RIVER) Labs are two Behavioral Science Institute research labs dedicated to experiments in Virtual Reality (VR). However, in 2013 it was decided to make RIVER Lab 1 available for other purposes as well, promoting RIVER Lab 2 as the prime facility for any VR research. The RIVER Labs are managed by Erik van den Berge of the TSG.

Head Mounted Displays

In RIVER Lab 2, five retro-reflective markers are attached to the Head Mounted Display (except HTC Vive) via a custom 3D-printed frame for tracking the participant's position and orientation; any internal tracking in the HMD is disabled.


As of November 2016, standard HTC Vive setups are available in both RIVER Labs. These setups use the Vive's own "Lighthouse" tracking system instead of the lab's, and a standard Lab Computer (with upgraded graphics card). No wireless solution is available for the Vive (yet), so the tracking area is limited by the length of the cable and the range of the Lighthouse tracking system. As of September 2017, the Vive in RIVER Lab 2 has been equipped with the Deluxe Audio Strap, which has built-in headphones.
