'Minority Report'-style goggles enable interaction with floating keyboards

Heads-up display can be used with any number of computer devices

The DDDR camera lens focuses the green light component at 11 inches and the red at 12.5-inches. The combined green and red components resolve to the strongest image signal at the midpoint between the two light components (about 11 13/16-in). The camera then captures the image signal at that midpoint as "input."

Because the camera does not register signals outside of the 11-in.-to-12.5-in. virtual target plane, it consumes no power other than when a fingertip is present.

Additionally, by detecting when a user's fingertip is in input range, the camera ensures that the user is intentionally trying to air-touch the virtual input device and that the camera does not mistake other user movements for input.

"A successful virtual touch triggers i-Air Touch to send a signal to the host device (a computer, laptop, smartphone, etc.) signifying that a key has been pressed or a touchscreen function has been touched," ITRI stated in a news release.

While the glasses cannot take photos, like Google Glass, they can be used with cameras in others kinds of wearable computers, the company said.

i-Air Touch technology is a real-world implementation of having a fictitious computer touch screen floating in the air. Similar to what has been seen in movies, such as Minority Report, i-Air Touch works as a virtual keyboard or touch screen for a computer or other interactive devices like a smartphone.
