The Leap Motion Controller, which lets you guide your computer by gesturing in the air, started shipping this week.
So who's ready to start typing e-mails in midair?
That's what DexType lets you do. It works with the , an $80 USB input device that tracks where your fingers are pointing.app
The DexType displays a range of keys on your screen for selection and also lets you draw characters in the air.
DexType "changes the Leap from an entertaining gadget into a genuinely useful tool by providing an alternative to the most important peripheral device of all -- the keyboard," according to a release from its independent developer, Zack Dennis.
The keys are displayed in a line across the bottom of your screen, arranged in QWERTY order from top to bottom and left to right, though other setups are possible.
The app has a predictive function that interprets what you're trying to type when pointing out letters, and treats keystrokes as letter groups. It chooses the most likely word -- for instance with a gibberish input like "nxopl" it will produce "hello."
Pressing deeper into the air will make the system choose a given letter. Numbers and symbols can be chosen by "drawing" them in the air, while a hand swipe can erase letters or words. Check out the demo below.
It seems like there's a steep learning curve here, and Dennis said the fastest typing speed recorded with DexType so far is only 25 words per minute. So this may not be ideal for writing your novel.
DexType also lets you surf the Web without clicking a mouse, select pages, and scroll through text. That's especially useful if you're busy doing something and your hands are dirty.
Do you think traditional keyboards will be replaced by virtual ones like DexType? Is anyone looking forward to penning letters in the sky, as it were?
