Abstract
We present the two-user Responsive Workbench: a projection-
based virtual reality system that allows two people to simulta-
neously view individual stereoscopic image pairs from their own
viewpoints. The system tracks the head positions of both users and
computes four images - one for each eye of each person. To display
the four images as two stereo pairs, we must ensure each image is
correctly presented to the appropriate eye. We describe a hardware
solution to this display problem as well as registration and calibra-
tion procedures. Theseprocedures ensure that when two users point
to the same location on a virtual object, their fingers will physically
touch. Since the stereo pairs are independent, we have the option
of displaying specialized views of the shared virtual environment to
each user. We present several scenarios in which specialized views
