While computer makers are focused on adding touchscreen capabilities to desktops, Leap Motion has created a $70 matchbox-sized device that adds gesture control to computers, essentially negating the need for touchscreens.
The technology uses two small cameras and multiple infrarad LEDs to track the motion of a person’s fingers with an accuracy of a hundredth of a millimeter, Technology Review reports. The second camera is used to prevent errors from a hand obscuring itself. All the processing is done by a drive software installed on the computer.
According to Leap Motion co-founder and CEO Michael Buckwald, “Leap provides the solution to ‘gorilla arm,’ a term used to describe the dubious ergonomics of a person repeatedly lifting his or her hands from the keyboard or mouse and reaching out to operate a computer’s touch screen,” the article states. “Users of Leap’s device can lift their hands just slightly off the keyboard and make more economic gestures with their fingers.”
“If you’re controlling a cursor [with Leap], you don’t have to move one-to-one with the screen, like you do with touch,” says Buckwald, so small motions translate to larger movements on screen, making interaction faster than using a mouse and keyboard.
“We’re working with lots of consumer OEMs and for laptops but also automotive and medical companies,” he adds. In the future, the technology will be applied to mobile devices as well as new technology such as head-mounted displays. Leap Motion anticipates the technology will one day enable complex 3D interactions.
Pre-production versions of the device have been sent to developers who have created various applications for the interface, including a aircraft game and photo-browsing program. The post includes an impressive video featuring these uses and others.
A newly uncovered Apple patent suggests 3D gesture control may be in the works for the company’s mobile devices.
“Forget relying solely on touch to control your Apple device,” writes Wired. “On future iPads, you may be able to control your tablet from across the room using 3D gestures, such as a swirl or swipe of the hand.”
Employing a front-facing camera, it may be possible to use 3D gestures to control graphical elements such as icons, media files, text and images on an iPad or iPhone. A toolbar would teach beginners pre-set options as well as allow users to customize their own gestures.
Another Apple patent indicates the company is working on an integrated projector for iDevices that would incorporate gesture controls for manipulating projected images.
