As anyone who's ever played a game of Duck Hunt is aware, there are ways of directly interacting with CRT monitors that don't require any modifications to the display itself (a la resistive overlays). A group of students from the University of Hasselt in Belgium have now taken that idea further than most, however, and developed a glove-based system that uses a pair of phototransistors in the fingertips to detect the electron beam as it makes its way across the screen. While not quite "multitouch," the student's current setup (dubbed CRTouch) does let them draw on the screen with one finger and call up additional options (like an eraser or color palette) with the second. Head on past the break to check it out in action.
