Augmented Reality vs. Virtual Reality: Key Differences and Applications
- The Sensorama, developed in 1957, was the first virtual simulator with 3D display, wind fans, motional chair, and odor emitters.
- The first VR-AR helmet, 'The Sword of Damocles,' was created in 1968. Jaron Lanier coined the term 'virtual reality' in 1987.
- Virtual Reality (VR) immerses users in computer-generated content through a headset, providing a fully immersive digital environment.
- Users need devices like high-spec computers, VR headsets, and sometimes handheld controllers for complete immersion in a VR world.
- VR software utilizes 3D modeling, animation, and physics simulation to create realistic and immersive worlds.
- Augmented Reality (AR) overlays digital elements on the real world, enhancing perception through smartphones, tablets, and AR glasses.
- AR uses advanced tech like computer vision and image recognition to overlay digital content on real-time images captured by cameras.
- AR applications include entertainment like Pokémon Go and Snapchat filters and business promotions through interactive triggers.
- Extended Reality (XR) enriches or replaces the real world with digital information and graphics, combining AR, VR, and MR technologies.
- Mixed Reality (MR) merges real and virtual environments, allowing interaction with both real and virtual items through headsets or eyewear.
