Technology turns air into a multi-touch screen - Technology & science - Science - DiscoveryNews.com - msnbc.com
Touch-sensitive frames have enabled surfaces to become interactive for years, but their size and responsiveness tend to be limited. A new prototype called "ZeroTouch" might look like an empty frame, but it's actually full of advanced capabilities.
The 28-inch ZeroTouch frame with scalloped edges can detect whatever moves around inside it. Fingertips, hands, arms, and even inanimate objects pass through an invisible two-dimensional optical web that tracks them. Put ZeroTouch on a computer screen and it turns into an interactive surface that can be manipulated with a stylus.
