This camera found on the top screen of your 3DS is used for games that use augmented reality or for 2D photos. You can switch between this inner camera and the 3D outer cameras.
The Circle Pad is a new input method never seen before on a Nintendo handheld console. It allows for analog-style control and movement. It moves in a nice and smooth 360 degrees, and it is concave which makes it a nice place to rest your thumb.
The + Control Pad provides digital input to your favorite 3DS games. It uses the same tried and true design previous Nintendo handhelds have, and improves on it. It's smooth and nice to use and provides 8-ways of directional input.
The 3DS touchscreen is an easy-to-use input method that can be used in creative and interesting ways. You can use the included stylus or even your own finger to touch the action on this screen. Below the touch screen are the Start and Select buttons, and a new Home button takes you to the 3DS Home Screen where you can choose a new game, or put the system to sleep.
The top screen is 3D ready, and doesn't require special glasses. Just turn up the 3D slider and watch as the game worlds gain depth and some even pop out in full 3D! Keep the console 9-14 inches away from your face to get the best 3D effect.
Not recommended for kids under 6.
Are the built-in speakers not cutting it for you? Is everything too loud around you? Just plug in your favorite pair of 3.5mm headphones into the headphone jack and feel immersed in the game worlds.
The ABXY buttons. Arranged in a familiar diamond pattern, these buttons allow you to control the action with these traditional inputs.
The classic power button. It powers on and powers off your 3DS. Afraid of turning off your 3DS by accident? Don't worry! If you press it once, it'll quit your game but won't turn off your system. Press and holding it will turn your system off, should you need to. But why turn off a world full of fun?
The key feature of the 3DS, the 3D slider. The slider allows you to adjust the depth of the 3D to your liking, allowing you to enjoy the 3D worlds without straining your eyes.
