Glasses-Free 3-D From Almost Any Angle


A relatively simple way of controlling the direction of light could lead to effective, inexpensive glasses-free 3-D screens for cellphones or tablets that function over a wide field of view, say researchers who developed the technique.

“We designed this technology to be particularly well-suited for mobile applications,” says David Fattal, a researcher in the Information and Quantum Systems Lab at Hewlett-Packard Laboratories, in Palo Alto, Calif. Fattal was speaking during a telephone press briefing on the project, which was described in a paper published in Nature yesterday. [Read More]
