Gesture control is wave of the future

Now that you've gotten used to touchscreen monitors and tablets, time to forget about all that.

Touchless computers are coming to a store near you, likely sometime next year. These are computers that operate with simple hand gestures — either through the use of sensitive sound-wave recognition or via cameras, similar to Microsoft's Kinect. And they are being developed and tested right now.

Intel Corp., which produces processors and chips for most of the laptop and desktop computers we use, is working on so-called perceptual computing software, part of which involves enabling hardware and software developers to bring gesture interaction to life on Windows 8 Ultrabooks and PCs.

The West Coast startup Elliptical Labs is slightly quicker to the race, having released a Windows 8 Gestures Suite last week that allows users to control a device using hand movements that are picked up via sound waves. Microsoft's new operating system, Windows 8, was built for touch integration, but some say the interface is also uniquely positioned to operate well with gestures.

Kinect brought motion recognition into mainstream gaming. But the key difference between Elliptic Lab's technology and camera-based motion recognition is the device doesn't need to "see" the gestures to pick them up.

"This has huge potential to change the way we interact with devices in the future," said Elliptic Labs product manager Morgan Kjolerbakken. "What we are launching now is the beginning of that."

Because its technology depends on sound waves, the user can gesture beyond the edges of the computer screen. For instance, swiping toward the screen could reveal a set of icons, and swiping your hand away from the computer could close an application.

"It's much more comfortable," Kjolerbakken said. "You can sit back and don't have to be in physical contact with the device. You don't get fingerprints on the screen."

Kjolerbakken said Elliptic has been contracted by hardware manufacturers, but he declined to disclose those companies.

As for Intel, a chief strategist at the company told the Herald that computers and laptops featuring this technology will become available in 2013.
