|  |     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.
