The mediated sketch table gives users the illusion of drawing on the same physical workspace; they can see each other’s drawings and each other’s hands.

Here's a picture explaining the basic setup of the system: ![]()
And here's a video showing the system in action: The project was done as part of a collaboration between LTU (our technology), KTH (the royal institute of technology), and TU Delft in the Netherlands. We've been to both TU Delft and KTH to present the project and participate in workshops. ![]() ![]() Finally, here's a video showing an early idea for rectangle detection based on color thresholding. We abandoned it in favor of AR marker detection, but it was a pretty cool idea. |
