An Infrared Pen with variable intensity The Xbox Kinect A standard computer

Design Engineering Collaborative at UC Berkeley Photoshop tools & Solidworks tools With visual feedback as to where your pen is

Acquire the 3D location of the infrared pen using the Kinect’s stereo imaging. Read the intensity of the infrared signal and translate it to the “brush stroke” weight. Determine the orientation of the pen for ideal brush paths. Correlate the velocity of brush strokes with brush weight. Use the GUI’s user input to apply the specified 2D cross section for the “brush”. Output a 3D model of what the user draws. Design Engineering Collaborative at UC Berkeley

Leap Motion’s sensor is limited to a 2x2x2 foot cube. The Xbox Kinect can image an entire room. Current Leap Motion software is good at using you hand positions to manipulate, rotate and exhibit current models. From the Leap Motion website: “you can point, wave, reach, and grab. Even pick something up and put it down.” Creating something is a different story… This Kinect software would change the way people create things from scratch in 3D, as opposed to just manipulating them.
