| Greetings,
Classic Wall Street Journal article! Several years behind
the real world, and loaded with incorrect terminology. Always dangerous
to get any kind of techie information from the greed-mongers.
Remarkable that there was none of the usual Journal off-the-wall
"Projected revenues for the year 2000 in this field". But American business
people love to read that kind of silly Japan-is-way-ahead-of-us
propaganda. Kind of sad, actually.
Everyone reading this file, I'm sure, already knows the name of the
field is VIRTUAL reality. But what you may not know is that
even though Jaron Lanier and his VPL company is way out in front in the
design of VR hardware (magic helmet, data suit, linked treadmill,
eyephones), DEC is actually doing some of the work for making virtual
reality useful. One of the projects at the Univ of Washington is the
design of the new Seattle shipping terminal using VR. You put on the
eyephones, don the data glove and suit, and mount the treadmill.
Then you're inside the virtual building (constructed CAD-fashion by the
architects). You walk through, notice that the walls are too close
together in one corridor, and ask the designer/programmers to pop the
walls out two feet. They do, and you continue walking through the
building (actually on the treadmill), looking left and right through
the eyephones, suggesting revisions to the building's construction.
And some of this work was funded by a ~2$miilion hardware grant from DEC
to the human interface lab at UW. The interesting part of this project
is that the treadmill walker can poke his head INSIDE the walls to look
at the placement of studs and insulation, or poke his head THROUGH the wall
to examine the landscaping outside.
What's even cooler than walking through the virtual world is touching
it, and the latest work from Lanier involves an implant into the data
glove that acts as a tactile simulation system. This has created a new
branch of computer science research called Dildonics. (No, I'm not
kidding. DILDOnics, because of the phalic shape of the tiny steel pins
in the glove implant.) The implant allows you to see a virtual vase on a
virtual table, reach out, and actually FEEL the vase as the steel
dildonic pins in the glove press against your palm when your hand
reaches the coordinates of the vase.
Every adolescent male who has heard of this system has suggested
the programming of rather obvious sexual fantasies into the system, and
in time, that will come (yikes, a pun). And the first people to
walk around in these virtual worlds have sometimes not wanted to ever
leave. Real Reality is so abrasive and nasty (for example, you write a
harmless note in a notesfile somewhere and get blasted from all kinds of
angry dudes with foreign accents!). So, the people who go into the
virtual worlds sometimes use them as the ultimate escapist drug.
The groups at DEC working in virtual reality are at Spitbrook
(Michael Good), and Southwest R&D in Albuquerque. Wicked cool stuff,
but no link to AI yet.
However, Artificial Life, another field still on the groundfloor
has real links to AI, and the people in my group doing Artificial Life
work are all KEs who also build expert systems. An A-Life system is
essentially a bag of little expert systems all of which cooperate and
compete for resources and space with each other, and can change their
own programming (genetic algorithm style) or have their programming
randomly changed by "mutation".
The fun applications are in ecosystem heuristic modelling, but
the real world applications are in industrial design (We're working on
both kinds of apps.) Tons of fun to come in in the morning and see your
screen full of electronic bacteria that you left growing overnight
in your microVAX.
Cool stuff. Gangs of fun. The VR/AL video arcades in 20 years are
going to be an absolute blast.

Dikk,
I'm only now catching up on my notes (breaching during an extended
period submerged in project work).
As far as I'm concerned there's nothing to forgive for "past notes".
I'm enjoying your very informative and entertaining contributions to
EURO_SWAS_AI - keep it up, and the Dave Barry notesfile could have
serious competition!
best regards,
pete.
