Augmented Reality

Augmented Reality (AR) overlays real-time, 3D-rendered computer graphics onto the physical world: it's the critical 3D human-computer interaction layer.

Augmented Reality (AR) is a technology that seamlessly blends real and virtual worlds; it is distinct from Virtual Reality (VR), which replaces the environment. The core mechanism involves real-time 3D registration, overlaying digital content onto the user's view of their physical space via a display (e.g., a smartphone or a head-mounted display). Key applications define its utility: mass-market success came via Niantic’s *Pokémon GO*, while enterprise adoption is driven by tools like the Microsoft HoloLens for complex industrial visualization and training. AR alters the ongoing perception of reality, delivering interactive, context-aware information directly where it is needed.
