	Smart Computing Encyclopedia Entry - light pen (Site not responding. Last check: )
		Light pens are optical pointing devices used to move a cursor or make a selection on a touch-sensitive screen.
		When the electron beam sweeps the back of the CRT (cathode-ray tube) face, it strikes the phosphor (at the pen’s location), and the light emitted by the phosphor is focused through the lens and onto the photo detector.
		Because light pens target specific pixels instead of finger-size buttons similar to those used on touch screens, they offer more active and accurate interaction between the users and the system.
