Subject: PHIL: Is 'Perfect Simulation' a Useful Goal?
Date: Mon, 22 Feb 1993 23:12:06 CST


1) As has been stated by a number of people, for many applications of VR
   perfect simulation of reality will be unnecessary or undesirable.

   I would agree that simulation indistinguishable from reality is not the
   ultimate goal of VR.  It doesn't have to be Nature, it just has to feel
   natural.

2) Pursuing _better_ simulation of reality, however, seems like one of the
   useful short term objectives for several reasons.

   Some applications will _require_ a high level of accurate simulation
   (for example the many and varied training _simulators_)

   People have pointed out that in other applications it will be desirable to
   "break the rules" of this world/reality.  Others have mentioned that the
   world doesn't have to be "real", as long as it is a good, intuitive
   interface.  I couldn't agree more, but remember that many of our intuitions
   (upon which our intuitive interface will be based) are based on our
   familiarity with "reality".

   I think it would be better to use "reality" as a starting point and break
   the rules selectively than to start from Chaos and work up (a fun pastime,
   but maybe an obstacle when you have something you want to do _now_).

Til Later,
  Kevin
