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.
