    Study Notes

    What Is Virtual Reality?

    • Virtual reality (VR) creates simulated environments using computer technology.
    • Users are immersed in a three-dimensional experience, interacting with virtual worlds rather than simply viewing a screen.
    • VR engages all five human senses, creating a rich, immersive experience.
    • Availability of content and computing power are key limitations for optimal VR experiences.

    Types of Virtual Reality

    • Non-Immersive Virtual Reality:

      • Users interact with a virtual environment while remaining aware of their physical surroundings.
      • Example: Video games.

    • Semi-Immersive Virtual Reality:

      • Offers partial virtual experiences, often used in education and training, like flight simulators.

    • Fully Immersive Virtual Reality:

      • Provides the most realistic experiences and may eventually engage all senses.
      • Example: Car racing games that simulate speed and driving dynamics.

    Virtual Reality vs. Augmented Reality

    • VR delivers an all-encompassing experience that fully obscures the real world.
    • AR overlays digital content on real-world environments, enhancing reality without completely masking it.

    Applications of Virtual Reality

    • Education: Improves engagement for students with special needs; tailored experiences increase responsiveness.
    • Fashion: Brands like Dior use VR stores to provide 3D shopping experiences online.
    • Gaming: Significant ownership of VR systems in gaming; substantial growth noted since 2020.
    • Manufacturing: Companies like Jaguar and BMW use VR for design experimentation, reducing prototype costs.
    • Journalism: Creates immersive storytelling experiences that provide first-person perspectives on events.
    • Law Enforcement: Enhances training realism and preparedness through simulated environments.
    • Marketing: Transforms consumer-brand interactions with immersive advertising experiences.
    • Museums: Offers virtual access to normally unreachable exhibits through mobile tech or headsets.
    • Convenient Conferences: Virtual meetings foster professional connections while saving resources.

    Challenges of Virtual Reality

    • Addiction: Users may become reliant on VR experiences, leading to social and psychological issues.
    • Health Problems: Prolonged use can cause disorientation, nausea, and loss of spatial awareness.
    • Screen Door Effect: Users may see pixelation due to proximity of the display, affecting immersion.
    • Loss of Human Connections: Over-reliance on VR can result in social disconnection and potential depression.
    • Real-World Performance Gap: Skills learned in VR may not translate effectively to real-world situations.
    • Expense: High costs of VR systems limit accessibility for some users.

    Future of VR in Business

    • VR is being integrated into retail and marketing for innovative consumer engagement; projected growth in retail VR technology is anticipated to reach $1.8 billion by 2022.

    Elements of Virtual Reality

    • Virtual World: A computer-generated environment that simulates real-world stimuli.
    • Immersion: Enhanced realism via graphical content and sound, using VR headsets and spatial audio.
    • Sensory Feedback: Encompasses multiple senses such as touch and taste, alongside audio and visual experiences.
    • Interactivity: Users can engage in real-time actions within the virtual environment, enhancing immersion.

    Degrees of Freedom in VR

    • 3 Degrees of Freedom (3DoF):

      • Tracks head movements (pitch, yaw, roll) but not physical translation.
      • Example headset: Oculus GO.

    • 6 Degrees of Freedom (6DoF):

      • Tracks both rotational movements and allows translational movements (heaving, surging, swaying).
      • Example headset: Microsoft HoloLens 2.
