Spatial Standards
  • A way to define the space in such a way that
    software could be added as a plug and play.
  • This is a function of the software and providing
    a common definition of the physical space.

Test Patterns
  • Centered on a physical location
  • -CAVE test patterns moved from center of the
    cave to center of the floor
  • Multiple test patterns to perform multiple
    functions
  • Alignment (CRT only?)
  • Scaled registration
  • Sub system test patterns (audience response,
    navigation, tracking)
  • Residual Error (specific for a projector / bend
    system)
  • Black Balance / Color balance
  • Users guide with test patterns so that
    non-engineers can correctly define issues

Standards

    market failure.
  • If the standard is not supported it doesnt
    matter.

The users speak..
  • Vendors who want to play seriously stand behind
    their products to help customise the solution and
    provide good customer service for a lasting
    relationship. Our project needs stable partners
    with upgradeable technology.
  • Symbiosis is not working well, but there is no
    reason for this other than the lack of industry
    standards. The viewing public would be best
    served, and so would industry, if greater efforts
    were made to respond to our needs.
  • The one area of this institution that does not
    need biodiversity is the technology
  • Exchange of knowledge, means exchange of
    content.
