Purdue University researchers have developed Shape-It-Up, which allows designers to create and modify items using gestures.

Purdue University researchers have developed the Shape-It-Up design tool, which allows designers to create and modify digital 3D models with their hands instead of a keyboard or mouse. The tool interprets hand gestures, like a natural user interface, and uses specialized computer algorithms and a depth-sensing camera.

Captured by a Microsoft Kinect camera, the user creates shapes by interacting with a virtual workspace as the shape is displayed on a large-screen monitor, and the resulting creations can be produced with a 3D printer. The tool could have applications in areas including games, architecture, art and engineering design.
