PALO ALTO (CBS SF) – Researchers at Hewlett-Packard Co. say they’ve developed a way to put glasses-free 3-D video on mobile devices with a wide enough viewing angle to allow viewers to see objects more fully just by tilting the screen.

Glasses-free 3-D in itself is not unique—companies like MasterImage 3D and Stream TV have demonstrated the technology on tablets and flat-screen TVs at consumer electronics shows.

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

Their findings will be published in the scientific journal, Nature, on Thursday.
