Nintendo 3D without glasses
June 22, 2010
At E3, the video-game industry's annual showcase, the star of the show was Nintendo's 3DS. The 3DS displays true 3D images without the use of special glasses. Unlike many 3D movies with objects that might appear to come whizzing out at you, the 3DS images appear to have depth that recedes into the screen.
The technology, known as a parallax system, works because the user holds the unit directly in front of the eyes at a fixed distance.
