The Nintendo 3DS is a clamshell design the same size as the Nintendo DSi. The bottom half contains a standard touch screen with 6 face buttons, 2 shoulder buttons, a + Directional Pad and an analogue "nub" for more accurate control, plus Home and Power buttons. The Start, Select and Home buttons are all integrated into the border around the screen.
The top half features a widescreen capable of displaying stereoscopic 3D images, as well as one camera above the screen and two cameras facing outward for taking 3D images. To the right of the screen is a slider control for altering the depth of 3D effect.
The system accepts Nintendo DS and 3DS games, and features an SD Card slot for saving data.
