Researchers at the Tokyo University show off a new input interface that translates in-air movements of fingers to computer commands. This interface enables you to use portable devices without even a touch.
Touchscreens are wondrous things, but nobody likes smudges, and attempts to magically prevent oil from sticking haven't always found success. The proper solution might not be in fancy screen coatings but rather in removing the touchability together. Tokyo University has developed a system that uses a high-res camera to identify where a finger is in 3D space, so moving around and even air-clicking is detected.
