AVIE Components
AVIE: External view
Panoramic Immersive Stereoscopic 3D Visualization System
This consists of a cylindrical silvered screen 4 metres high and
10 metres in diameter on whose internal surface 360 degree stereographic
3D panoramic image sequences can be projected. A set of 12 projectors
in six stereoscopic pairs, each pair supplying
60 degrees of the whole image. The stereoscopic effects will be created
through the use of opposed polarising filters. The high throughput
of data will be handled by eight high-performance computers, each generating
an on-the fly image sequence for one projector.

Intelligent Vision-Based Interaction and Motion Tracking Systems
This provides a multi-purpose sensory environment for unencumbered tracking
of viewer movement and gesture, offering a large range of motion capture
and interaction design functions. Covering the entire AVIE area, the
system is able to accurately track the spatial position and movements
of up to thirty people. When applied to smaller groups of up to five
people, it generates high-resolution three dimensional voxel models
of their body movements and gestures, enabling real time motion tracking
and some gesture recognition.

Panoramic Spatialized Audio System
Directly complementing the unique visualisation and interaction features
of AVIE is its spatialised audio system. This is a twentyfour channel
system with custom surround audio application software. This system
enables fully immersive 360 degree placement of sound anywhere around
the viewers. As with visual projection, the audio system can be coupled
with the Intelligent Vision-Based Interaction and Motion Tracking
Systems to allow voices to ‘follow’ projected characters,
or to be activated only when viewers move within ‘earshot’
of the virtual audio sources, or correctly perform some task.
