Va.Si.Li-Lab

a VR-Lab for Simulation-based Learning

Abstract

Va.Si.Li-Lab was established as part of the project "Digital Teaching and Learning Lab" (DigiTeLL) at the Goethe University Frankfurt. It has since evolved into a highly capable and flexible VR framework for enabling simultaneous, multi-user engagements.
