VR Basics: Understanding Virtual Reality

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.
