Gunze's new touchscreen tech knows who's touching it

Touchscreens can't differentiate between you, your friend or your cat. Truth is, they're actually amazingly simple pieces of technology without much in the way of brains. A new type of display shown off at the International Nanotechnology Exhibition & Conference in Tokyo last week does imbue the panels with at least enough smarts to tell people apart. Gunze Ltd pairs a special capacitive screen with electrodes, which a user touches with one hand while interacting with a game or app. The immediate use would be for table-top arcade games, which would differentiate between up to four different players based on what particular circuit they complete when touching the screen. We wouldn't be shocked if a version of the tech started showing up in multi-player video poker machines and bar games relatively soon.
