The Collaborative Workforce group is a research group at Georgia Tech that I was a member of for two semesters. I designed and implemented multimedia systems, web applications, and human-computer interfaces to support remote collaboration for design and research teams. Specifically, we built a web interface (optimized for the iPad) that allowed the user to control all of the distance learning equipment in a classroom, like the cameras, projectors, TVs, audio gear, etc. We also worked with a TI SoC to do Region of Interest video annotation. Video takes up a lot of bandwidth, so by designating a region of interest, we can serve the user only the part of the video that really matters. For something like a lecture, that’s easy to do, since you’re generally only watching a professor walk around. If you’re watching a slide deck, you can drop the frame rate a lot since you’re essentially watching pictures that change once every minute or so. Here’s the dev board we developed on:

I don’t have any screenshots from the software we wrote, but it was all in PHP and Javascript. The UI was basically a floorplan of the rooms (the local room and the remote room). Then you could drag and drop connections between devices, so you could drag a camera from the local room onto a TV of a remote room and that would automatically set up the connection between those devices.

Here’s a paper that we wrote on it. This project won first place in the embedded category of a design competition that Cisco had that year. It was judged by several Georgia Tech professors and some Cisco engineers.
