Large-Scale, Real-Time Motion Capture

Squidball is a large-scale, real-time interactive video game that uses motion capture technology to create a unique and energetic gaming experience. In the world’s largest calibrated motion capture volume, the game debuted on August 12th, 2004, with an audience of 4,000 people, at the Los Angeles Convention Center, as pre-show entertainment for the SIGGRAPH Electronic Theater. SIGGRAPH is the Association of Computing Machinery’s Special Interest Group in Graphics.

Squidball is played with several (12 at SIGGRAPH) large (approx. 4ft in diameter), helium-filled weather balloons in retroreflective jackets – these are the input devices for the game. By throwing, batting and bouncing the balloons throughout the playing field (which, in this case, was approximately 400x200x40 cubic ft), the audience plays to eliminate the on-screen targets, which are represented on a giant 40-foot video screen that also displays scoring and timers. As a result of this unusual motion capture application, the audience sees the balloons move across the two-dimensional video projection screen as they simultaneously interact with them in the 3-D space. Winning the game inspires and requires collective cooperation among the entire audience.
