The I/O Brush is a cool graphic tool that allows you to take color, texture, and movement of any object and draw with that characteristics - kind of like the real life version of the eyedropper tool in Photoshop!
In our current prototype, the brush houses a small CCD video camera in its tip with a ring of white LEDs around it. Force sensors are also embedded inside of the brush, measuring the pressure that is getting applied to the bristles. When the brush touches a surface, the lights around the camera briefly turn on to provide supplemental light for the camera. During that time, the system grabs the frames from the camera and stores them in the program.
This very cool brush, invented by Kimiko Ryokai, Stefan Marti, and Hiroshi Ishii of MIT, won an award at the 2005 Industrial Design Excellence Award.
