Fakespace, Inc.
The Immersive WorkBench, from Fakespace, Inc., available with DUO
technology, is a virtual model display that supports natural interaction
with computer-generated 3D imagery, and enables users to manipulate virtual
objects in the same "hands-on" way they work with real objects on a desk or
table. It has an adjustable viewing surface, from horizontal toward
vertical, so that the reachable work area and viewing volume can be adjusted
according to individual preferences.
DUO-Dynamic Display System, which enables two simultaneous and individually
head-tracked stereo pairs to be displayed on VMDs. With this Dual User
Option (DUO), two people can now share a workspace, and collaborate within a
virtual model space that is accurate for both users.
