HP develops glasses-free 3D display for smartphones

LOS ANGELES: Researchers at Hewlett-Packard Co. have developed a way to put glasses-free 3-D video on mobile devices with a viewing angle so wide that viewers can see an object more fully just by tilting the screen.

Glasses-free 3-D is not unique. Nintendo Co. Ltd.'s 3DS handheld allows video

related stories game play in 3-D without glasses, but it requires players to look straight into the screen with their noses centered.

HP's researchers have found a way to make images viewable in 3-D from angles up to 45 degrees from center in any direction -up, down, side-to-side or diagonally. That means viewers can see a person's face with one ear blocked from view, but reveal the ear by swiveling the screen.

The company's findings will be published in the scientific journal, Nature, on Thursday.
