we perceive our reality, or a virtual reality, there are processing
techniques at work in our perceptual apparatus that make it understandable. The art of creative media is to provide the
participant visual, audio, and existential cues that evoke an impression,
an emotion, or a narrative understanding.
Each media type has its own scope as far as what cues it
can provide at any given time.
While Stephenson, Lanier, and McKenna envisioned cyberspace
over 15 years ago, Virtual Reality Modeling Language (VRML) and
interactive 3D are just emerging as a viable platform for diverse
rich-media production. Adding
the real-time dimension of space allows participants to see and
hear the action from any location and even through different eyes! This presentation explores the methods of creating
user perceptions in VRML worlds and provides some examples of the
principles in practice.
following exploration is adapted from a powerpoint presentation
given at the 14th Annual Stuttgarter
FilmWinter Festival for Expanded Media.
The included VRML97 examples were created to demonstrate
the perceptual nature and technological capabilities of this 3D
media type. They are purely illustrative and utilitarian in nature
and may lack the flair of 'professional' design...
after the presentation, one german designer remarked "Thank
you for your ugly, male style, it was very helpful!". A
dubious translation, but bystanders confirm it was a compliment
browser is recommended especially for the Audio Perception example.
