Nintendo 3DS includes two screens. The bottom touch screen makes use of a telescoping stylus that is stored in the unit itself. The top screen displays 3D visuals to the naked eye. Looking at the screen is like peering through a window into a world where characters and objects have true depth. The system also has a 3D Depth Slider that lets players select the level of 3D they enjoy the most. The 3D effect can be ratcheted up to the highest level scaled back to a more moderate setting or even turned off pletely depending on the preference of the user.
