AlloSphere

The AlloSphere Research Facility (branded as AlloSphere) is a research laboratory at the University of California, Santa Barbara. Housed in a theater-like pavilion with a spherical structure made of opaque material, it is designed to project computer-generated imagery and sound. The facility is used for a wide range of applications, including geographic information systems (GIS), scientific research, artistic exploration, and other forms of data visualization. The AlloSphere grew out from the university's departments of electrical engineering and computer science and the media arts and technology program. The AlloSphere is housed at UCSB California NanoSystems Institute building, "CNSI," or Elings Hall, a 62,000-square-foot (5, 800 m2) facility that opened in 2007. The AlloSphere is intended to integrate technology and media. The AlloSphere includes a three-story cube that has been insulated extensively with sound-absorbing material, making it one of the largest echo-less chambers in the world. Within the chamber are two hemispheres of 5 meter radii, made of perforated aluminum. These are opaque and acoustically transparent. There are 26 video projectors, to create as much of a field of vision as possible. The loudspeaker real-time sound synthesis cluster (140 individual speaker elements plus sub-woofers) is suspended behind the aluminum screen resulting in 3-D audio. Computatio
