Japanese mobile phones already let users shoot films and share them with friends. It may not be long before the images go another step - becoming completely three-dimensional. Japan's Hitachi, Ltd has developed a lightweight 3D display that can potentially be adapted for mobile devices such as telephones.
The gadget, using what is known as stereoscopic vision display, weighs only one kilogram (2.2 pounds) and resembles an upside-down, multiangular pyramid full of mirrors on top of a liquid crystal display. "It's very small and portable," Rieko Otsuka of Hitachi's Advanced Research Laboratory said on Tuesday.
