What is Augmented Reality (AR)?
- AR enhances the real world by overlaying computer-generated visuals, sounds, and information.
- Unlike VR, AR does not replace reality but adds digital elements to it.
- Major AR devices include Microsoft HoloLens, Magic Leap, and AR-enabled smartphones.

How Does Augmented Reality Work?
1. Hardware Components
- AR requires smart glasses, mobile AR applications, and head-mounted displays (HMDs).
2. Software & Content
- AR experiences are powered by computer vision, AI algorithms, and spatial computing.
3. Tracking & Interaction
- Marker-based AR, markerless AR, and LiDAR scanning enhance accuracy and real-world interaction.
Key Applications of Augmented Reality
AR enables immersive product visualization, remote assistance, and real-time navigation.
1. Gaming & Entertainment
- AR gaming offers interactive digital overlays in real-world environments.
- Games like Pokémon GO and Minecraft Earth showcase the immersive power of AR.
2. Healthcare & Surgery
- AR assists in surgical navigation, medical training, and diagnostics.
- AR headsets like Microsoft HoloLens provide real-time imaging for doctors.
3. Education & Training
- AR brings interactive textbooks, virtual dissections, and anatomy simulations to life.
- Used in aviation, military, and industrial training simulations.
4. Retail & E-Commerce
- AR-powered virtual try-ons allow customers to preview clothing, makeup, and furniture.
- Brands like IKEA Place and Sephora Virtual Artist use AR for immersive shopping experiences.

Differences Between AR, VR, and MR
