Re: Visidep

    Thanks to all who responded with information about the Visidep 3-D TV
process.  Just for kicks, I did an AltaVista search on Visidep, and came up
with the following references:

A thesis:

(Copyright by David Drascic 1991., but I assume it's o.k. to quote a small
piece of it:)
Kinetic Depth Effect is often used as a depth cue for graphics systems for
data visualisation and
display purposes. The closest approximation to a continuous motion system
available for real
world video operation is the VISIDEP(TM) system (Jones et al, 1984). This
system works by
alternating images between two closely placed cameras at speeds between 5 and
15 Hz, giving the
illusion that the remote world is rocking. While systems that utilise the
Kinetic Depth Effect can
indeed convey a strong sense of depth, and can give some information about
the relative placement
of objects in the remote world, they do not convey this information as
unambiguously or as
automatically as does a stereoscopic display, and they are difficult to use
for any interactive
purpose, where the operator must act within the moving display space.
