A researcher at MIT’s Center for Future Civic Media has developed software that lets anyone quickly stitch together random displays to form what he calls a Junkyard Jumbotron. Using the Junkyard Jumbotron, groups of people can more easily view data, graphics or other information on what is essentially a larger virtual display.
To create the virtual display, a user goes to the Junkyard Jumbotron creation Website to receive a unique URL. This URL is then entered on all the devices that will be used in the virtual display system. Once the URL is entered, each device will display a visual code.
The next step is to take a photo of all the ensemble of displays exhibiting the codes. The photo must then be e-mailed or uploaded to the creation Website. At this point, software developed by the center analyzes the photo to figure out where all the displays are located.
After this step, any image that the user desires to display is simply e-mailed to the site, and the software automatically slices up that image and places pieces on the individual devices. This forms the larger virtual image. A user can them manipulate the image on any device zooming and panning across devices.
The source code of this project is available on github.
