A Taiwan-based nonprofit R&D organisation announced Wednesday a virtual display that allows users to control virtual keyboards and touchscreens that float out in front of users.
The Industrial Technology Research Institute (ITRI) said its new technology uses special glasses and DDDR (defined distance with defined range) camera technology to allow users to see and interact with virtual data, images and devices with finger strokes.
The heads-up display technology resembles the sci-fi technology displayed in the movie Minority Report, starring Tom Cruise.
The new i-Air Touch technology is being developed for an array of devices, including PCs and laptops, wearable computers and mobile devices, that allows a user's hand to be free of any physical device such as a touchpad or keyboard for touch input.
i-Air Touch glasses allow virtual interaction with computer screens.
i-Air Touch's see-through capability enables a user wearing a pair of special eyeglasses to see and interact with a virtual input device, such as a touchscreen or mouse that appears to be floating in the air, while still being able to see and interact with the real world.
"i-Air Touch creates new possibilities for wearable and mobile computing by freeing users from the distraction of locating and touching keys on a physical input device for hands-free computing and improving security over voice commands," Golden Tiao, deputy general director of ITRI's Electronics and Optoelectronics Research Laboratories, said in a statement.
ITRI plans to license the patented technology to manufacturers. The company sees the heads-up display technology being used in not only consumer arenas, but also for medical applications such as endoscopic surgery and any industrial applications that benefit from hands-free input.
The DDDR camera is the key functional component of i-Air Touch, ITRI said. The camera discerns the virtual images for interaction, but it conserves battery power, which is a major issue facing manufacturers of many wearable computers, the company stated.
How it works
The camera uses a phase- and color-coded lens to discern an object at a predetermined distance of 11 inches to 12.5 inches away from the eyeglasses. The camera detects and activates only in the presence of a fingertip within that input range. The virtual images shut off if a user's fingertip isn't present, allowing a clear field of view.
The DDDR camera essentially captures the image of a user's fingertip out in front of it and splits the image into green and red color codes to provide segmentation in image processing, while phase coding provides distance and depth perception of the fingertip.
i-Air Touch allows multiple screen/keyboard interaction.
