Changes

= [[Augmented Reality ]] (AR) is a technology that overlays computer-generated images, sounds, and contextual data onto the real world, creating an interactive composite view. Unlike [[Virtual Reality]], which replaces the user’s surroundings entirely, AR supplements reality—letting digital [[Pokémon]] appear on streets, in parks, or even on a player’s desk. Since its launch in July 2016, Pokémon GO has continuously expanded its AR tool-set, evolving from a simple camera overlay into sophisticated, persistent, and shared experiences that leverage surface detection, spatial mapping, and cloud anchoring.<!-- :contentReference[oaicite:0]{index=0} -->

''Augmented reality'' (AR) in '''Pokémon GO''' allows digital Pokémon, items, and UI elements to be rendered over the live camera feed, appearing as if they occupy physical space around the Trainer. Since the game’s launch in July 2016, developer '''[[Niantic]]''' has expanded AR from For a simple overlay broader introduction to advanced experiences such as [[AR+]], [[GO Snapshot]], [[Buddy Adventure]], Reality Blending, AR Mapping, and [[Pokémon Playgrounds]]. These features rely on Apple’s [[ARKit]], Google’s [[ARCore]], and Niantic’s own [[Lightship]] ARDK and [[Visual Positioning System]] (VPS).<ref name="ARPlus2017" /><ref name="ARPlusAndroid2018" /><ref name="RealityBlending2020" /> == Definition and context ==AR in '''Pokémon GO''' uses '''marker-lessconcepts, inside-out tracking''' to lock 3-D Pokémon models to real-world planes detected by the device camera, enabling players to walk around, view them from different angles, and take photographs. The concept aligns with see the [[inside-out tracking]] article on the external [VR & AR Wiki](https://vrarwiki.com/wiki/Inside-out_tracking)VR & AR Wiki].<ref name="VRARwiki" />

== Device support Challenges and limitations ==AR functions require gyroscope* **Battery and processing load** – Continuous camera, sensor fusion, and real-equipped phones that pass ARCore/ARKit certification; time rendering drain power, especially on older or budget devices can disable AR to save battery.<ref name="CatchingARHelp" /> Advanced options like Reality Blending * **Environmental constraints** – Very dim or Playgrounds have limited device and level rollover-bright settings reduce surface-tracking accuracy; textured, well-outslit areas work best.<ref name="RealityBlending2020ARCoreDoc" /><ref name="Playgrounds2024" * **Accessibility** – Advanced features require ARKit-/>ARCore-certified phones; players on legacy hardware can disable AR to maintain performance.
