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 empty 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. Infrared sensors and LEDs provide a clear visualization of any object within the frame. The tech is an inexpensive way to turn large monitors into interactive multi-touch screens

How ZeroTouch Works ?

The ZeroTouch frame contains 256 infrared sensors and 32 LEDs, and each light blinks at a specific frequency that is read in sequence by the sensors. The prototype is so responsive because each LED is blinked in sequence about 2,400 times a second, Moeller said. The frame is connected to a computer via USB, which provides power and collects the data.
