With the whirl of a thumb, Georgia Tech researchers have created technology that allows people to trace letters and numbers on their fingers and see the figures appear on a nearby computer screen. The system is triggered by a thumb ring outfitted with a gyroscope and tiny microphone. As wearers strum their thumb across the fingers, the hardware detects the movement.

Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment.
