he (ieorgia Resource Center is also home to Atlanta Vision, the third incarnation of the < )lympic \ ideo devek iped by the Multimedia Laboratory. Atlanta Vision differs from its predecessors in that "its the Atlanta skyline changes, we can .c\d a building or remove a building, says Dyer. "It is designed in an expandable way that, as far as I know, no oneelse has ever attempted." Atlanta \ ision begins with a view of the world showing cities which have previously hosted the Olympic Games. < llympic ribbons travel from those cities to Atlanta, where they turn into five colored rings floating above the skyline. By rolling a trackball, viewers highlight one of the rings or select an icon on the screen

to begin their o w n interactive mulli media tour of the 1996 Summer

< >lympics. Selecting one ring, lor e \ ample, lakes the viewer to Stone Mountain for video, still images and data about the facilities for bicycling, equestrian and other events to be held there. Other selections bring information about Atlanta's transportation facilities, downtown housing, the i )U mpic village or other events. "You can see specific details ol each of the various venues, or if you want to take a tour of the cilv and see the various activities, you can also do that in a visually exciting way," explains Dyer. "There are also short video sequences on the history of the Olympics, the (tfympic move ment and Atlanta's win." To maintain the detailed information and organize the video, sound and images, the system relies on an Oracle relational data base. Each screen is driven by a separate Ib.M PS 2 computer, which is itself coordinated by a computer communicating through a token ring network.

A unique photographic technique allows viewers to see a XT >( (-degree panorama at each location, "comparable to being in a swivel chair mov ing around and looking at the a< ttv i lies," says Dyer. 'fhe images were shot from a helicopter by producer and lab codirector Michael J. Sinclair, using a motor-driven 35 mm camera. In the studio, the still frames were scanned. corrected for distortion and then electronically composited to provide a complete />(>() degree Strip picture. Dyer hopes the Atlanta Vision system will be made at other loot lions, perhaps as part of a proposed Atlanta Visitor's Center. â&#x20AC;˘ Backdropped b y a n interactive Atlanta m a p , overlaid w i t h Olympic rings, is Fred Dyer o f the Georgia Resource Center.
