Nintendo 3DS

The Nintendo 3DS is a family of handheld game consoles released from 2011 to 2020, distinguished by an upper display that produces stereoscopic 3D without glasses.

Autostereoscopy: Display technology that creates a stereoscopic image without requiring the viewer to wear glasses. The 3DS uses a parallax barrier to send different images to each eye.
Nintendo DS: Nintendo’s dual-screen handheld console family, first released in 2004. The 3DS inherited the DS layout, backward compatibility, and broad software library.
Nintendo 3DS game library: The collection of games released for Nintendo 3DS systems, including exclusive titles and ports. Its range shows how developers used the console’s two screens, 3D display, and controls.
Nintendo 2DS: A Nintendo handheld that plays Nintendo 3DS games but lacks stereoscopic 3D and uses a fixed, slate-like body. It offered a lower-cost entry into the 3DS library by removing the defining 3D display.
Parallax barrier: A patterned layer that directs separate image views toward different viewing angles. It produces the 3DS screen’s glasses-free depth effect, with a narrow comfortable viewing zone.
Nintendo DSi: A camera-equipped 2008 revision of the Nintendo DS with downloadable software support. It was the immediate predecessor whose features and design the 3DS extended.
StreetPass: A Nintendo 3DS feature that exchanged game data between nearby consoles in sleep mode. It turned carrying the handheld in public into a source of encounters and game rewards.
Nintendo 2DS XL: A clamshell Nintendo handheld that plays 3DS games without stereoscopic 3D. It kept the larger-screen clamshell design while omitting the 3DS family’s signature display effect.
Nintendo 3DS Circle Pad: An analog control stick built into the original Nintendo 3DS handheld. It added continuous directional control beyond the system’s traditional digital pad.
Nintendo 3DS game card: A proprietary flash-memory cartridge format used for Nintendo 3DS retail games. The cartridges carried 3DS titles while the console also supported compatible Nintendo DS cards.
