When Munir Mandviwalla brought his children to Philadelphia’s Comcast Building last year, he took one look at the Comcast Experience HD Video Wall in the building’s lobby and immediately felt like a kid in a toy store.
“It’s beautifully done,” he said of the massive display that claims to be the world’s largest four-millimeter LED screen. “Gigantic, extremely high resolution and they use it extremely well. I looked at it and I said, ‘Hey, I want one too.’”
As the founding chair of the Management Information Systems department at Temple University’s Fox School of Business and Management, Mandviwalla was in a position to make that personal dream come true.
He had long craved an unorthodox classroom space suited to the Sophocratic style with which he likes to teach, where students share ideas and the instructor’s function isn’t just to lecture, but to promote a group dialogue.
After considering a host of larger integration companies who offered solutions that Mandviwalla characterized as restrictively standard, he chose a smaller vendor whose viewpoint jibed with Mandviwalla’s unusual vision.
The result: The Speakman Hall Room 200 at Temple University’s Fox School of Business and Management.
Integrator David Spiegel of Huntington, Pa.-based Audio General, Inc. designed a system that provides a wireless interface through which up to 12 laptops can display their screen images through three Optoma TX765W wireless DLP projectors, mounted overhead, onto a wall coated with projector paint. Additional options allow one user to use all three high-brightness, 1024x768 projectors projectors at a time to broadcast multiple images, or the three projectors can team up to broadcast one single, sweeping image onto the 21-foot wall.
“You don’t need a screen because you want to use the whole wall anyway – and it looks cooler,” Mandviwalla said of the decision not to use a projector screen.
The real beauty of the install is that all of these pieces flow together without utilizing a traditional control system, as David Spiegel, the integrator on the project, explained.
Instead of channeling the wireless signals through switchers and multiplexers, they go directly
