Techniques of Perception with
X3D
- Nicholas F. Polys &
Luciano de Soares
Date:
Friday, 1st April
Time: 9am - 90 minutes
When we
perceive our reality, or a virtual reality, there are common mechanisms at
work in our sensory and cognitive systems that help us structure and interpret
our various sensory streams. This tutorial will introduce and review important
research from the fields of Psychophysics and Perceptual Psychology in order
to provide participants with a working appreciation of the human senses and
how their mechanisms can enable and constrain good design.
The tutorial
will cover the following topics:
- Perception for Design
- Visual cues and markers
- Aural cues
- Attention
- Sensory Buffers, Working
memory: change blindness and causality
- Approaches and examples for
mapping data to perception
- Information Visualization,
Scientific Visualization
- Sonification
- Techniques for enhancing
the Virtual Environment with abstract information
- information-Rich Virtual
Environments
The power
of media is to provide the participant visual, audio, and existential cues
that evoke an impression, an emotion, or a narrative understanding. Newspaper,
phone, radio, movies all have their own scope as far as what perceptual cues
they can provide at any given time. While Stephenson, Lanier, and McKenna
envisioned cyberspace over 15 years ago, realtime virtual reality is just
emerging as a viable platform for diverse rich-media production. This presentation
explores the methods of creating user perceptions in X3D worlds and provides
some examples of the principles in practice.
There are no
prerequisites for this tutorial.
Authors:
Nicholas
F. Polys has worked in the creation and management of digital assets
for virtual environments for more than 6 years. From 1999-2002, Mr. Polys
served on the Web3D Consortium Board of Directors and produced the Consortium's
semi-annual Software Development Kit. As a key contributor to the X3D specification,
Nicholas has conducted courses including: Introducing X3D (SIGGRAPH 2002
and local chapters: Boston, San Francisco), and Graphics Publishing with
X3D (Web3D 2002). Mr. Polys has published on cutting-edge techniques for
design and publication of real-time networked 3D in the ACM, IEEE, SPIE venues
and a recent book chapter. His current research at Virginia Tech and the
Virginia Bioinformatics Institute concerns Human-Computer Interaction and
3D user interfaces for Information-Rich Virtual Environments.
Luciano
Pereira Soares is a Phd. candidate at the University of S縊 Paulo, Brazil.
He received his degree in Computer Engineering in 1999 from the UFSCar.
From 1998 to 2000 he worked at SGI Brazil. In 2001 he joined USP with a
research focus on Virtual Reality and cluster computing and managing the
VR Center, having been responsible for the integration and configuration
of the graphics PC cluster and the developing the software that is currently
powering the 5-sided CAVE installed at USP.
