Chris Harrison, a researcher at Carnegie Mellon University whose human-computer interaction work we've written about previously, will demonstrate his new scratch inputtechnology. The system turns any surface into an instant input device by sensing the unique sound produced when a fingernail is dragged across it.
The interface is small enough to fit into a mobile device, Harrison says, and could thereby turn any surface the device is placed upon into an interface.
