In this podcast episode, Ravi and I unpack the difference between augmented reality and virtual reality, work through real device examples like Magic Leap and Intel Vaunt, and debate where AR and VR genuinely add value for business and data visualisation versus where they're just gimmicks. We also dig into the Facebook/Cambridge Analytica fallout and what it means for data privacy and policy.

## Key takeaways

- AR overlays information onto the real world (Pokémon Go, phone camera face detection); VR replaces it entirely with an immersive environment, needing far more computational power
- Dedicated VR hardware (Oculus Rift, HTC Vive, HoloLens) exists because phone-based VR overheats and can't deliver the compelling experience the tech promises
- Devices like Magic Leap and the now-cancelled Intel Vaunt project images directly onto the retina rather than onto glass, giving always-sharp augmentation that only activates when you look at a specific cue
- The most convincing data use cases for AR are contextual - viewing shop-floor sales performance in situ, or spotting manufacturing bottlenecks right where they occur - not rotating 3D pie charts or scatterplots for novelty
- Policy and ethics are lagging badly behind the hardware, especially around always-on cameras, consent, and data walled gardens like Facebook restricting API access post-scandal
