Nintendo has announced its new product, Nintendo 3DS at E3 (Electronic Entertainment Expo) 2010. The Nintendo 3DS takes the popular Nintendo DSi design and adds a 3.5-inch wide 3D display on the top half. You will see 3D images/videos on the screen without glasses.

Some game makers have supported the Nintendo 3DS. One of the new titles announced is a new version of Nintendogs. Nintendo also announced a new Mario Kart game as one of the upcoming titles for the Nintendo 3DS. And the Sims 3 is also coming to the Nintendo 3DS.

While playing the games, the player will be able to adjust the 3D effect by sliding a slider on the right-hand side of the upper screen. A new button (above the directional pad on the left-hand side) will also offer tighter controls for 3D games.

The back of the Nintendo 3DS features a pair of cameras that players can use to take 3D photos.
