At this year’s spatial cognition conference in Kloster Seeon in Bavaria, Germany, Bernhard co-organized a workshop on “VR in Spatial Cognition Research” with Klaus Gramann.
He also also presented a paper on “Why the heck do we have not clue where we are in VR?” — below is the video of it. (after 10min the camera died, so you’ll have to look at the paper for final conclusions, here’s the reference, official paper title & link:
