ABSTRACT
Multi-user virtual worlds are proliferating on the Internet. These
are two and three dimensional graphical environments inhabited
by users represented as digital actors called "avatars".
Through this medium, a wide variety of Internet users are participating
in a large scale social experiment and collaborating on a variety
of projects. The inhabited virtual world is an exciting new medium
for HCI professionals including interaction and graphic designers,
and educators and researchers focused on distance learning and
teleworking. It also appeals to children and ordinary users of
the Internet as a vast new digital playground and a venue for
personal expression. This tutorial will introduce participants
to a variety of inhabited virtual worlds and give them hands-on
experience in collaboratively building and interacting with other
users in the worlds.

INTRODUCTION
For the past two years, the Internet has played host to a new
medium: the mult-user virtual world. These environments are graphically
rendered in two or three dimensions and represent the presence
of participants as digital characters known as "avatars".
Participants navigate their avatars through these digital spaces,
communicate with other users, build structures, teach, learn,
and engage in a variety of collaborative activities. On-line virtual
worlds represent an new frontier for interaction design, computer
supported cooperative work and learning and touch upon many other
interest areas of HCI.
This tutorial will introduce HCI professionals and novice users
alike to the medium of multi-user virtual worlds. No prior knowledge
of 3D modeling, VRML or online communication is required.
Origins of the virtual worlds medium
This technology could be seen as
a graphical extension of MUD and MOO environments but it exhibits
some of its own unique characteristics, including:
- Vivid shared social environments
exhibiting properties of an emergent culture
- Collaborative construction of
large scale spaces including buildings and full towns, artwork,
areas containing digital biota and soundscapes
Virtual worlds borrow from both the
virtual reality and computer gaming field. However, this medium
does not require the kind of immersive equipment (such as head
mounted displays) found in virtual reality systems. In addition,
virtual worlds employ fast 3-D graphic rendering engines found
in gaming environments but their application is almost purely
social.
THE VIRTUAL WORLDS TO BE USED

in a virtual wedding.
The tutorial will employ several virtual world environments, including:
Onlive Traveler (see Figure 1), AlphaWorld (see Figure 2), CyberHub,
the Palace, Virtual Places, V-Chat, general VRML 2.0 environments
and others which become available by the time of the tutorial.
Within the virtual worlds, special areas will be constructed or
designated for use by tutorial participants. The Virtual University
server within AlphaWorld will be made available for the tutorial.
GOALS OF THE TUTORIAL
The learning objective of the tutorial
is to give participants enough background and hands-on experience
of this new medium that they can use on-line inhabited virtual
worlds in their research or professional projects. It is our hope
that the tutorial will also encourage more HCI professionals to
participate in the development of the virtual worlds medium.
TUTORIAL EXERCISES
These collaborative exercises will involve the formation of teams,
who will brainstorm a design of a shared, 3-D space and its interfaces.
The design will be presented to the entire tutorial for a critique
and then built collaboratively within a virtual world. The exercises
are designed to address key issues in 3-D interfaces, virtual
community, cooperative and participatory
interaction design, usability testing, teleworking, CSCW
and CSCL, the World Wide Web and social issues.
TUTORIAL INSTRUCTORS
Demonstrators will include members of the Contact Consortium,
a non-profit research membership organization dedicated to the
development of the virtual worlds medium. Throughout 1995 and
1996, the Consortium has engaged in extensive usability testing
of virtual worlds provided by its member companies, which include
Worlds Incorporated, Intel, Black Sun Interactive, Time-Warner
Interactive, Nippon Telephone and Telegraph (Software Division),
Microsoft, Philips and others. The Consortium has engaged in the
collaborative construction and staffing of a virtual town (Sherwood
Forest), a virtual university (theU) and has hosted in regular
social experiments in these online worlds.
Other demonstrators will join us from around the world as avatars
in-world to assist with teaching, demonstration and participate
in the collaborative exercises themselves.
Demonstrators will help participants learn how to navigate, communicate
and build within virtual worlds, including AlphaWorld, PointWorld,
thePalace, Virtual Places, Utopia and others as they become available
closer to the conference date. The collaborative construction
exercise will take place inside AlphaWorld or possibly another
environment.
