Study Notes

Augmented Reality (AR)

  • AR is a technology that blends the digital world with the physical environment, overlaying digital information onto the real world.
  • AR uses computer vision, mapping, and depth tracking to generate content for the user.
  • AR cameras collect and process data to send the right content to the user, enhancing the physical environment in real-time.
  • AR can be experienced with smartphones or special hardware.
  • Applications of AR include:
    • Texting, embedding imagery and videos
    • Printing, advertising, and digital content
    • Interpretation apps and 3D tools for 3D real-time games

Virtual Reality (VR)

  • VR is a fully immersive experience that allows users to undergo a real-world-feeling.
  • VR attempts to regenerate computer images and videos to produce real-life visual experiences.
  • VR systems use computer vision and advanced graphics to generate 3D images and video by adding depth and reconstructing scale and distances between static 2D images.
  • VR headsets and controllers with sensors enable users to explore and control 3D environments.
  • Applications of VR include:
    • Enhancement of fictional realities in gaming
    • Flight and battlefield simulation for military training
    • Training device for PTSD and sports training
    • Fear therapy through fictional or real-life scenes and scenarios
    • Medical training for graduating students and learning new skills in a safe environment

AR vs VR

  • VR creates an immersive virtual environment, while AR augments a real-world scene.
  • VR is 75% virtual, while AR is only 25% virtual.
  • VR requires a headset device, while AR does not.
