Multi-user communication and interaction in a virtual world
Rhodes university, 2001Supervisor : Prof. Shaun Bangay
Project Aims:
• Investigate how to put together a multi-user environment
• Have volunteers test the environment
• Analyze data from tests
Methodology – The Experiment
Need :• A situation that needs people to
communicate in order to solve it• Something simple that will take
about 10 min. • Must have different stages that we
can compare.
Methodology – The Experiment cont.
The proposed experiment:• Water bucket that needs to be
used to fill a bucket on a seesaw.
Seesaw Buckets
Characters Water
Methodology – The Environment
• Choose travel technique.
Quake strafe style
with mouse look
Rotating style
Vs.
Methodology – The Environment cont.
• Bendable character meshes.
Vs.
Flexible mesh Rigid mesh
Methodology – The Environment cont.Required character movements. • Walk (from sea to seesaw.)• Pick up object.• Carry an object.

Carrying an object
Methodology – The Environment cont.
Objects required to fulfill the needs of the experiment.
• Water (sea.)• Buckets.• Seesaw.• Particle spray system (leak in
bucket.)

Design considerations cont.
• Simple collision detection (only in one plane)
Within quad
Within radius

Sound component
• Problem – You can only open the sound device once, and send one stream of data to it.

Results cont.
• Significant questionnaire results:
How clear was sound quality – Understandable 3/5How often did you speak
Beginning - Little to Normal 2.6/5Filling buckets - Little 2/5After killing the dino. - Little 2/5
How effective was communication – Ok to Easy to interact 3.5/5
How realistic did the game feel – What I expected 3/5How easy was it to navigate - Better or the same as other
games 4/5
