Access Grid

The Access Grid supports large-scale distributed meetings across the internet. Our system has 3 projectors which can display dozens of video streams from cameras at remote locations onto a 18' wide section of wall. Three cameras mounted around the room provide full coverage for other groups to view our conference room. Echo cancelling microphones provide high-quality audio support. All of this combines to provide a flexible and fully interactive environment for taking part in large discussions across the internet.
