Understanding AR vs. VR vs. MR vs. XR: A Breakdown of Extended Reality Technologies
Terms like AR, VR, MR, and XR are often used to describe new ways of interacting with the world around us. While these acronyms may seem confusing at first, they all fall under the umbrella of “Extended Reality” (XR). Let’s dive into each technology to better understand what they are, how they differ, and where they overlap.
AR | VR | MR | XR |
---|---|---|---|
Virtual elements overlayed on the real world. | Fully virtual experience. | Anchored virtual elements that can interact with the real world. | Umbrella term for AR, VR, and MR. |

What is Extended Reality (XR)?
Extended Reality (XR) is a catch-all term that includes all immersive technologies—Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR). Essentially, XR refers to any form of interaction that blends the physical and digital worlds to varying degrees.
XR can be viewed as an evolving field where digital environments extend beyond the boundaries of traditional screens to give users new ways to experience, interact, and engage with the world around them.
Augmented Reality (AR)
Augmented Reality layers digital elements—images, text, sounds—over the real world in real time. These digital components enhance the user’s perception of the physical environment but do not replace it. AR is most commonly experienced through smartphones or wearable devices, like smart glasses.
Key Examples of AR:
- Pokémon Go, where digital creatures appear in real-world locations.
- IKEA Place, an app that lets users visualize how furniture would look in their homes.
- Snapchat filters that overlay digital effects on real-time images of your face.
AR works by using sensors and cameras to track the user’s environment and superimposing virtual elements on top of the real world. This technology is considered one of the more accessible forms of extended reality due to the widespread use of smartphones.
Virtual Reality (VR)
Virtual Reality creates a completely immersive digital environment that replaces the physical world. Unlike AR, which overlays elements on top of reality, VR transports users into a fully digital space. This requires a VR headset, like the Oculus Quest or PlayStation VR, which covers your field of vision to block out the physical world entirely.
Key Examples of VR:
- Beat Saber, a VR rhythm game where players slash blocks in time to music.
- Google Earth VR, where users can explore cities and landscapes in a fully immersive environment.
- VR training simulators for pilots or medical professionals to practice skills in a risk-free virtual environment.
In VR, users interact with the digital world using handheld controllers or motion sensors. Because of the full immersion, VR provides a much more intense, transformative experience than AR, though it requires more specialized hardware.
Mixed Reality (MR)
Mixed Reality blends real-world and digital elements in a more integrated way than AR. MR allows users to interact with both physical and virtual elements simultaneously, creating an experience where digital objects interact with the real environment. The key difference from AR is that the digital objects in MR are aware of and respond to the physical world.
Key Examples of MR:
- Microsoft HoloLens, where digital objects can be manipulated as if they existed in the physical space.
- Spatial, a collaboration tool that allows users to meet in virtual environments while still interacting with physical tools like whiteboards or notes.
Mixed Reality relies on advanced sensors, cameras, and spatial mapping to understand the environment in real-time. This means that digital objects can interact with real-world surfaces, making the blend of realities much more seamless than traditional AR.
Extended Reality (XR)
Extended Reality (XR) is the umbrella term that covers all these technologies: AR, VR, and MR. It includes any form of technology that alters our perception of reality, whether that means overlaying digital information on top of the real world (AR), immersing us in a fully digital environment (VR), or blending the two worlds together (MR).
XR is often used as a term to describe the evolving landscape of immersive technology as a whole, where the lines between physical and digital realities become increasingly blurred. As hardware and software continue to evolve, XR represents the future of how we might experience and interact with the world in entirely new ways.
How They Compare:
- AR: Enhances the real world with digital elements but doesn’t replace it.
- VR: Immerses users in a fully digital world, replacing the physical world.
- MR: Combines both physical and digital elements, allowing them to interact in real time.
- XR: An umbrella term for AR, VR, and MR technologies.
Grouping and Overlaps
- AR and MR: Both augment the real world but to different extents. MR integrates digital and real-world elements more seamlessly, while AR primarily adds a layer of information on top.
- VR and MR: While VR fully isolates users from the physical world, MR keeps users grounded in their surroundings while adding immersive elements.
- XR: Represents the spectrum of reality modifications that AR, VR, and MR provide, creating a continuum between fully physical and fully virtual experiences.
As the lines between physical and digital worlds continue to blur, understanding the distinctions between AR, VR, MR, and XR becomes increasingly important. Whether we’re catching Pokémon in our backyard (AR), traveling through fully immersive digital landscapes (VR), or manipulating digital objects in the real world (MR), these technologies are transforming how we interact with the world around us.
Each form of extended reality serves different purposes, but all share the goal of enhancing our perception and interaction with both the physical and digital realms.
