This is Scientific American's 60-Second Tech. I'm Larry Greenemeier. Got a minute?
The future will likely bring two main ways of telling our computers, tablets and smartphones what to do: voice commands and hand gestures.
Voice is already off and running with technology like Apple's Siri.

Now HP says that within a few months you'll be able to control its gadgets using hand signals.
Beginning in mid May, HP customers will be able to buy an $80 USB-plugin controller made by a company called Leap Motion.
The company says it can track individual finger movements with 1/100th of a millimeter precision.
HP plans to eventually embed Leap Motion's controllers in its products.
Leap Motion will also have an app store called Airspace where HP users can buy gesture-controlled games and other software.
Other companies, including Microsoft with its wrist-worn "Digits" prototype, want to make scrolling through screens, playing games and watching video a snap, sometimes literally.
The bad news: once your computer learns hand signals, it will know when you're flipping it off.

Thanks for the minute, for Scientific American's 60-Second Tech. I'm Larry Greenemeier.
