sci.virtual-worlds Visual Displays Frequently Asked Questions
(FAQ)

The latest edition of this FAQ can always be retrieved from
www.hitl.washington.edu /scivw/visual-faq.html

This faq replaces the previous HMD FAQ, it is meant to supply product
information regarding visual displays in virtual interface technology.
Vendors are listed alphabetically with product cross reference. The
product listings are listed alphabetically by product name with the
vendor cross reference. Field of View is described as horizontal field
of view in degrees (H) by vertical field of view in degrees (V).

Subject: -1- Display Types

CAVE (TM): CAVE Automatic Virtual Environment, a projection-based virtual environment system that surrounds the viewer with up to four screens and allows both physical and virtual objects to occupy the same space.  The CAVE is trademarked by the University of Illinois.

head-coupled: Displays or robotic actions that are activated by head motion through a head tracking device. (In this FAQ, head-coupled displays are indicated by "Weight:  boom). 

head mounted display (HMD): A set of goggles or a helmet with tiny monitors in front of each eye to generate images seen by the wearer as three-dimensional. Often the HMD is combined with a head tracker so that the images displayed in the HMD change as the head moves. (from Mancetta, Carol and Blade, R.A. Glossary of.Virtual Reality Terminology. http://ijvr.uccs.edu/manetta.htm)

monocular displays: display for one eye.

see through display: display that allows wear to see the virtual image
superimposed over the real world. The wearer can "see through" the
virtual image. (from Mancetta, Carol and Blade, R.A. Glossary
of.Virtual Reality Terminology. http://ijvr.uccs.edu/manetta.htm)

Spatially Immersive Display (SID): Spatially immersive displays utilize
wrap-around (panoramic) video displays to create an unencumbered,
ultra-wide field of view, walk-in immersive environment.  Displays are
typically produced by front or rear surface video projection onto
cylinder, dome, torus, or rectilinear screens.  High resolution over a
wide field-of-view can be maintained by projecting multiple video
ports which are tiled or soft-edge blended over the screen surface to
create a continuous, seamless or near-seamless, geometrically correct
image when properly rendered.  SIDs may or may not utilize stereoscopy
or head-tracking depending on application requirements. (definition

shutter glasses: Glasses that alternately block out the left and right
eye views in synchrony with the computer display of left and right eye
images to provide stereoscopic images on the computer screen. (from
Mancetta, Carol and Blade, R.A. Glossary of.Virtual Reality
Terminology. http://ijvr.uccs.edu/manetta.htm)

Virtual Model Display: Virtual model displays utilize a limited
field-of-view stereoscopic or autostereoscopic display which is most
effectively used to display three-dimensional models.  Such displays
are not highly immerive, but are the optimal display medium for
virtual models or other limited field-of-view content. (definition
courtesy of Ed Lanz, Spitz Inc.)

wearable computing: Wearable computing hopes to shatter this myth of
how a computer should be used. A person's computer should be worn,
much as eyeglasses or clothing are worn, and interact with the user
based on the context of the situation. With heads-up displays,
unobtrusive input devices, personal wireless local area networks, and
a host of other context sensing and communication tools, the wearable
computer can act as an intelligent assistant, whether it be through a
Remembrance Agent, augmented reality, or intellectual
collectives. (from the MIT Wearable Computing WWW page)
