Abstract:
We present the two-user Responsive Workbench: a projection-based
virtual reality system that allows two people to simultaneously 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 calibration procedures.
These procedures 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 might be useful.
