What is the key defining characteristic of Mixed Reality (MR)?
Mixed Reality (MR) is distinguished by the depth of integration between digital and physical: virtual objects are spatially aware of real surfaces, respond to real lighting, and can be occluded by real objects. This requires world understanding — plane detection, scene reconstruction, depth sensing. Apple Vision Pro and HoloLens 2 represent MR. Contrast with AR (overlay, less interaction with real world) and VR (fully virtual).

What is Augmented Reality (AR) and how does it differ from MR?
AR places digital content on top of a real-world view — classic examples: Pokémon Go (overlays on a phone camera view), IKEA Place (placing furniture models in your room), navigation arrows on a windscreen HUD. The virtual elements do not necessarily understand the physical environment. MR goes further: virtual objects respond to real surfaces, can be occluded by real objects, and integrate spatially. The line between AR and MR is increasingly blurry.

What is Virtual Reality (VR) and what defines a fully immersive VR experience?
VR uses an opaque headset that blocks out all real-world light, replacing it entirely with a rendered 3D environment. Fully immersive VR combines: a wide FoV display, 6DoF head and controller tracking, spatial audio, low latency (under 20ms motion-to-photon), and high refresh rate (90Hz+). These together produce 'presence' — the psychological sensation of actually being in the virtual environment.

What does XR (Extended Reality) mean as an umbrella term?
XR (Extended Reality) is the collective term for AR, VR, MR, and the entire spectrum between them. Using XR avoids needing to list each variant separately, and acknowledges that the boundaries between AR, MR, and VR are becoming less distinct as technology evolves. The WebXR API (W3C), OpenXR standard (Khronos), and most industry literature use XR as the inclusive term.

What is the 'reality-virtuality continuum' (Milgram scale)?
Milgram and Kishino's reality-virtuality continuum (1994) is the foundational model for understanding the XR spectrum. At the left: real environment (pure physical reality). At the right: virtual environment (pure VR). Between them is Mixed Reality — including Augmented Reality (mostly real, some virtual) and Augmented Virtuality (mostly virtual, some real). This model explains why MR encompasses both AR and certain VR-with-real-elements experiences.
What does this Wearables & Spatial Computing Language exercise cover?
This exercise, "MR / AR / VR Vocabulary", tests your understanding of wearables & spatial computing language vocabulary and phrasing through 5 multiple-choice questions drawn from real workplace scenarios.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is completely free — no account, sign-up, or payment required.
How many questions does this exercise have?
This exercise has 5 questions. Each one presents a realistic sentence or scenario with multiple-choice options and an explanation once you answer.
What happens after I answer a question?
You'll see immediate feedback showing whether your answer was correct, along with a short explanation of why — then a button to move to the next question.
Can I retry the exercise if I get questions wrong?
Yes. Once you reach the results screen, click "Try again" to reset your answers and go through the exercise from the start as many times as you like.
Do I need to create an account to take this exercise?
No account is needed. Your answers are scored in your browser during the session — nothing is saved to a server, so you can jump straight in.
Is my progress saved if I leave the page?
No — progress within an exercise resets if you navigate away or reload. Each exercise is short enough to complete in a few minutes in one sitting.
Who is this Wearables & Spatial Computing Language exercise for?
It's designed for IT professionals and learners who want to sound natural discussing wearables & spatial computing language topics in English — useful for meetings, documentation, interviews, and day-to-day communication with English-speaking teams.
How is this different from reading a glossary or blog article?
Exercises like this one are active recall drills — you have to choose the correct term or phrasing yourself, which builds retention faster than passively reading a definition.
