3-D Display:

Graphics display research is working on concepts that will
enhance the perception of 3-D space.  Developments include a
user/computer interface that is worn as one would wear a pair of
eyeglasses.  The small, lightweight device gives the wearer a
free space perspective as the data display appears to float in
front of the user's eyes (Rowell, 1989).  Research initiatives at
the Media Lab (M.I.T.) have developed a helmet device that places
the user within a computer generated 3-D construct, so that as
the user turns, the view into the modeled space changes (Brand,
1988).
