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 plug-in controller made by a company called Leap Motion
. The company says it can track individual finger movements with one one-hundreth 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.
