Differences Between Metaverse, AR, VR, MR, and XR | IT Passport Exam Prep

What is the Metaverse

A three-dimensional virtual space built on the internet is called the metaverse. Through avatars, users can interact with others, engage in commercial activities, entertainment, and work. Its prominence surged in 2021 when Meta (formerly Facebook) changed its company name.

Differences Between AR / VR / MR / XR

AR (Augmented Reality)

AR is a technology that displays virtual objects overlaid on a smartphone camera feed. The real world remains unchanged, with additional information displayed on top. Specific examples include distance displays on golf courses and car heads-up displays.

VR (Virtual Reality)

VR is a technology that fully immerses you in a virtual world by wearing a headset. You are cut off from the real world, with only the virtual environment in your field of view. It is used in VR games, real estate walkthroughs, and medical training.

MR (Mixed Reality)

MR is a technology positioned between AR and VR, characterized by the ability to touch and manipulate virtual objects. For example, you can press a virtual button with your hand or rotate a virtual blueprint.

Devices

The head-mounted display (HMD) is a representative device for experiencing the metaverse and AR/VR/MR. An HMD is a display worn on the head, with notable products including the Meta Quest, Apple Vision Pro, and Microsoft HoloLens.

Metaverse Use Cases

The metaverse is used across various fields. In entertainment, there are virtual concerts and VR games; in business, virtual offices and meetings. In education and training, it is used for medical surgery simulators and disaster drills; in e-commerce, for virtual try-ons and real estate tours. Additionally, NFTs are gaining attention as assets within the metaverse (detailed in What is Blockchain).

Key Points for the IT Passport Exam

In the IT Passport exam, the differences between AR, VR, and MR, the definition of the metaverse, and the role of head-mounted displays are frequently tested. Be sure to accurately grasp these distinctions.

Typical Past Exam Question Patterns

• "Which technology overlays virtual information onto the real world?" → AR
• "Which technology fully immerses you in a virtual world?" → VR

Study Tips

It's easier to understand if you remember AR as "add," VR as "immerse," and MR as "merge." A simple definition of the metaverse as a "3D virtual space" is sufficient. Memorize one representative device each, such as the Meta Quest and HoloLens.
