Motion-sensing technology that allows users to interact with computers without ever touching a keyboard or a controller is not new and has been integrated into popular video game systems like the Xbox 360, but a small start-up from San Francisco says its new product vastly improves on that technology by making the user experience more natural and life-like.

Leap Motion introduced its motion-sensing controller at the CES technology expo in Las Vegas this week. The iPod-size controller is outfitted with the company's proprietary software, which it says can track individual finger movements to 1/100th of a millimetre.

"The Leap sits in front of you and connects to the computer, and it creates a bubble where the user can reach in and basically interact with the computer as if they were interacting with the real world, using small precise movements, using fingers," Leap Motion CEO and co-founder Michael Buckwald told Peter Nowak, who is covering the tech expo for CBCNews.ca. 

The company spent four to five years developing the Leap software, which Buckwald said is orders of magnitude more precise and responsive than existing technology and is the only motion-sensing software to be able to track multiple fingers.

"This is not an iterative technology," he told Nowak.
