This is a project of the master program digital healthcare of FH St. Pölten (Austria). This prototype simulates an x-ray tube, which is controlled by gestures. This is supposed to be an approach to reduce germ transmission as well as to increase ergonomics for radiographers. For the development, Leap Motion was used for hand tracking, VVVV for processing and Arduino for mechatronics. Gemafreie Musik von musicfox (www.musicfox.com)
