There’s a great new user interface technology that literally lets you dance to make a 3D design. The technology is called Shape-It-Up and uses a Kinect camera to allow the user to interact with 3D objects. It was created by the Purdue C Design Lab. They’re now collaborating with the company ZeroUI to look at commercial applications. ZeroUI specializes in gesture-based interfaces. Here’s a great video of Shape-It-Up in action.
