Live DemonstrationLive Demonstration

Professor Peter Beier will discuss the technical features of the CAVE. This will be followed by a demonstration and test rides.

Logs of your individual runs created at the time of operation will be available for viewing after lunch.

A box lunch will be served after the demonstration
