Introduction to Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)

  • Virtual Reality (VR): A fully immersive digital environment that completely replaces a user's real-world surroundings with a simulated world.
  • How VR Works: VR headsets or goggles display 3D environments, tracking head and body movements for realistic interactions. Advanced systems include handheld controllers, gloves with haptic feedback, or motion-sensing rooms.
  • VR Applications: Entertainment (gaming, fantasy adventures), education (training simulations), and healthcare (pain management, phobia treatments, physical therapy).

Augmented Reality (AR)

  • Definition: AR adds digital elements to the real world, enhancing the user's environment with computer-generated visuals, sounds, or other sensory information. AR differs from VR by keeping the user in their real environment, enhancing it with supplementary info.
  • How AR Works: AR typically uses a smartphone, tablet, or AR glasses with sensors and cameras to detect the environment and overlay digital content in real-time.
  • AR Applications: Mobile apps and games (e.g., Pokémon Go), retail and shopping (virtual try-ons), and navigation and tourism (directions, landmarks).

Mixed Reality (MR)

  • Definition: MR merges the real and virtual worlds, enabling coexistence and real-time interaction of digital and physical objects. Unlike AR, which overlays digital elements, or VR, which replaces the environment, MR seamlessly integrates both.
  • How MR Works: Advanced hardware (e.g., Microsoft HoloLens, Magic Leap) uses multiple cameras, depth sensors, and spatial mapping to track the real-world environment allowing digital objects to be positioned and interact within the environment.
  • MR Applications: Industrial and manufacturing training, healthcare (surgical planning), design and engineering.

The History of Virtual Reality (VR)

  • 1950s: Early concepts of immersive experiences, like Morton Heilig's Sensorama (multi-sensory experiences).
  • 1960s: The creation of the first head-mounted display (HMD), known as the Sword of Damocles.
  • 1970s: VR technology's use in military and research contexts (e.g., flight simulators).
  • 1980s: Increased VR research and development (e.g., VPL Research, Inc.).
  • 1990s: VR's early concepts and experiments in merging digital and real-world environments.
  • 2000s: Development of more accessible VR systems.
  • 2010s: VR enters the mainstream with affordable headsets, attracting greater audience interest.
  • 2020s: VR expands beyond entertainment (education, healthcare) fuelled by enhanced technology and advancements.

The History of Mixed Reality (MR)

  • 1994: The term "Mixed Reality" is coined by Paul Milgram and Fumio Kishino.
  • 1990s: Early MR concepts and experiments with technologies merging digital content with physical environments.
  • 2000s: Development of initial MR headsets and systems (see-through).
  • 2010s: Introduction of consumer-level MR devices (Microsoft HoloLens).
  • 2010s-2020s (Present): Ongoing development and integration of advanced technologies into MR (AI, computer vision).

5 Innovative Types of Virtual Reality (VR) and Augmented Reality (AR)

  • Non-immersive VR: The user remains aware of their physical surroundings and engages with virtual environments through standard displays.
  • Fully immersive VR: Users are entirely disconnected from their surroundings and interact completely with the virtual environment.
  • Semi-immersive VR: Users interact with 3D environments but remain partially aware of their real world surroundings.
  • Augmented Reality (AR): AR overlays digital objects onto the real world, enhancing or augmenting physical environments without replacing them.
  • Collaborative VR: Allows multiple users to share and interact within a virtual environment.
