What is Extended Reality (XR)? Extended Reality (XR) is an umbrella term for all immersive technologies that extend reality by combining the virtual and physical worlds. Components: ● Virtual Reality (VR): Fully immersive virtual environments. ● Augmented Reality (AR): Overlaying virtual content onto the real world. ● Mixed Reality (MR): Interaction between physical and virtual elements in real-time.

● Virtual Reality (VR) ○ Fully immersive digital environments. ○ Example devices: Oculus Quest, HTC Vive, PlayStation VR. ○ Applications: Gaming, simulations, virtual tours. ● Augmented Reality (AR) ○ Overlaying virtual elements on real-world environments. ○ Example tools: ARKit, ARCore, Snapchat filters. ○ Applications: Retail, education, marketing. ● Mixed Reality (MR) ○ Blending digital and real-world environments. ○ Example devices: Microsoft HoloLens, Apple Vision Pro. ○ Applications: Design, collaboration, industrial training. Components of XR

● Hardware ○ Headsets (Oculus, HoloLens, Magic Leap) ○ Smartphones and tablets (AR experiences) ○ Sensors (LiDAR, cameras, haptic gloves) ● Software ○ Development platforms: Unity, Unreal Engine, ARKit, ARCore. ○ WebXR frameworks: A-Frame, Three.js. ● Core Concepts ○ SLAM (Simultaneous Localization and Mapping) ○ Spatial Computing ○ Cloud Rendering Technologies Powering XR

● Healthcare ○ Surgical simulations, therapy, diagnostics. ○ Example: VR for surgery training. ● Education ○ Immersive learning environments. ○ Example: AR-enabled textbooks and VR field trips. ● Retail and Marketing ○ AR try-ons and interactive advertisements. ○ Example: IKEA Place App (AR furniture placement). Application of XR

● Gaming and Entertainment ○ VR/AR immersive gaming experiences. ○ Example: Pokémon GO, Beat Saber. ● Industrial Training ○ Simulations for hazardous environments. ○ Example: AR for equipment maintenance. Application of XR
