The VENLAB:
Andrew Duchon in the VENLAB (an old organic chemistry
lab). He is wearing the
Kaiser PV80 HMD, with the InterSense receiver pods and inertial cube
attached on top.
Notice the SoniDisks attached to the grid in the ceiling which are
all connected to the platform
in the middle of the room. 50 foot cables are required for the
HMD and the tracking system.
The Funhouse:
Our most popular demo environment. 5-10% of
the guests have problems "jumping" down the cliff. The carousel
turns and plays carousel music. The elevator can rise about 100
meters, and the tunnel will turn you upside down.
