Touch to the "force" DoCoMo developed 2.5-inch naked 3D screen

The Japanese operator NTT DoCoMo has previously shown an open 3D screen that can expand the viewing angle by 30%, and at the Ceatec 2010 Japan High-tech Expo earlier this month, NTT DoCoMo also displayed an interactive, naked-eye 3D screen. Here we take the display of NTT DoCoMo as an example to introduce its interesting, in the figure below, DoCoMo naked eye 3D screen shows a crawl in the color of empty.

In fact, this thrust is achieved by the magnetic force, the screen behind the wire coil, the addition of electric current will produce magnetic force, the latter and touch the tip of the magnet on the role of Repulsion.

In detail, the display is surrounded by a camera that tracks the position of the nib, and when the nib touches the chameleon's tongue, the coil is applied to the electric current, creating a magnetic force, and then applying the repulsion to the stylus. Users will actually feel the repulsion.

DoCoMo at the show is a 2.57-inch 3D screen, which is based on the principle of cylindrical lenses, with eight viewing angle, horizontal perspective ±20°.

But DoCoMo has not yet decided when to scale the display, saying the technology is mainly used to enhance future information interaction, and that there are several other technologies in development, but they are now investigating the market's demand for the technology.
