IllusionHoleStation Concept rendering The IllusionHoleStation is an interactive, stereoscopic display system, providing multiple users a perspective correct vision. Multiuser interaction was main priority. The IllusionHoleStation is based on the idea of the Illusion Hole developed at Human Interface Lab at the Osaka University. Later Prof. Dr. Bernd Fröhlich developed that idea further and the IllusionHoleStation was created.
