Access Grid is a collection of resources and technologies that enables large format
audio and
video based
collaboration between groups of people in different locations. The Access Grid is an ensemble of resources, including
multimedia large-format displays, presentation and interactive environments, and interfaces with
grid computing middleware and
visualization environments. In simple terms, it is advanced
videoconferencing using big displays and with multiple simultaneous camera feeds at each node (site). The technology was invented at
Argonne National Laboratory, Chicago.
