A 360 degree, auto-stereoscopic, 3D display prototype from Sony was showcased in the Emerging Technologies section at the recent Siggraph 2010 Conference/Exhibition.
The cylindrical unit measures 13cm in diameter and 27cm in height. It can be connected to a PC, or other device, through a digital video input port. No special glasses are needed to see the 3D image.
The display is also equipped with a gesture sensor that enables the display to be controlled interactively using hand motions.
The 3DS is a new hand-held game console from Nintendo which can provide 3D effects – no glasses required. Announced during the recent E3 exhibition conference and scheduled for general availability before March 2011.

The 3DS has two screens – the top screen is a 3.53 inch widescreen LCD display with a resolution of 800×240 pixels, 400×240 pixels per eye to provide the auto-stereoscopic three-dimensional effect. The bottom screen is a 3.02 inch touch panel with a resolution of 320×240 pixels.
The 3DS weighs approximately 8 ounces and is 5.3 inches wide, 2.9 inches long, and 0.8 inches tall.
The system features a slider on the side of the device to adjust the level of the 3D effect, a round nub analog input called the “Slide Pad”, an accelerometer, and a gyroscope. In addition, there is an infra-red communicator port situated on the top of the unit.
