A prototype of 3D display without glasses at Microsoft

At the infancy of 3D general public, as manufacturers seek to impose the wearing of glasses to make us particularly enjoy the World Cup football in relief, research and development we are actively seeking to freed from the artifice prohibitive.

Microsoft is developing to do a new type of lens, through its research laboratory. If the principle of self-stereo , which will separate the two channels on the side of the screen with lenticular sheet (and not at the viewer) is already on the market, it requires a point of view, bounded on the viewer .

A lens for directing light
The new lens of Microsoft, thinner below than above, allows for it to control the direction of light using LED placed below. So light in the bottom of the lens, is reflected by a number of times until the desired output angle. The shape of the lens being immutable, this orientation is determined by the entry point of light. The system sits behind the LCD panel and replace the backlight.

A camera to locate the audience
The laboratory prototype display uses a camera to monitor the position and movements of a maximum of two spectators, and direct channels to their eyes. This process was already known but the computing power required to track the location of the audience in real time was not so far reached.

The method could eventually find other application areas, such as to replace the backlight of the screen of a laptop and switch between the private, for which the visual field would be voluntarily restricted mode public.

Microsoft introduced last month in Seattle a first prototype display at an international exhibition on display, but the technology is still in its infancy and no date is for marketing Daylight Saving Time.
