One of the most common methods of creating the illusion of 3D is the autostereoscopic display, which is based on parallax: each eye is presented with a slightly different angle of a scene. Often this is done with many tiny microlenses, each projecting a small amount of light. Although this method has many advantages and is already being used in commercial products, such as the Nintendo 3DS, its narrow viewing angle is still a problem for expanding its use to larger displays.
