The visionOS execution context where an app's windows appear alongside other apps and the user can see the real world is called:
The app runs in the shared space (alongside other apps) — this is the default mode in visionOS, analogous to a regular app window on macOS.
2 / 10
The visionOS mode where the app takes over the entire field of view and the real world is hidden is called:
The fully immersive mode occupies the entire field of view — this mode is used for VR-like experiences; the real world is completely replaced by the app's environment.

In visionOS, a floating rectangular display that can be positioned in 3D space is called:
The window is a 3D panel — visionOS windows are volumetric panels that the user can place and resize in their physical space.
4 / 10
The Apple framework used to create and render 3D content, animations, and physics simulations in visionOS apps is called:
RealityKit renders 3D content — Apple's primary 3D rendering framework for visionOS, providing entities, components, and physics simulation.

The input gestures native to Vision Pro that require no physical controller are described as:
The app uses natural gestures (pinch, wrist tap, look) — Vision Pro uses eye tracking for targeting and hand gestures (primarily pinch) for selection, with no physical controller.

During a code review of the VisionProSceneBuilder class, Sarah asks David: 'The documentation mentions using spatial anchors to persist object positions across scene updates. Could you elaborate on how we're actually implementing that and what happens if the user moves between apps?'
Spatial anchors are crucial for maintaining object positions in Vision Pro's persistent scene. Using `SpatialAnchor.create()` with a unique identifier allows the app to track its position relative to the world, which is key to functionality like remembering where an object was placed when the user switches apps. Options A and D misrepresent spatial anchor usage; Option C incorrectly states they are limited to single-app persistence.

You're drafting a Slack message to the team explaining why you've added a delay before triggering a RealityKit physics simulation. Mark asks: 'Why are we adding that latency?'
In the context of RealityKit, latency refers specifically to the time delay between user input and the corresponding update in the physics simulation. Introducing a small delay (like 50ms) is a common technique to smooth out jitter caused by processing variations and improve the overall responsiveness and visual quality of the simulation – Option A provides a vague definition; Options C and D are demonstrably false.

The following API response is received from the Vision Pro's 'Eye Tracking' service: `{"trackingQuality": "low", "confidenceLevel": 0.75}`. During a standup update, you need to explain this to your team. What do these values mean?
The trackingQuality parameter in the API response indicates the current performance of the eye tracking system – 'low' suggests limitations or potential issues. The confidenceLevel represents the probability that the tracked position is correct; a value of 0.75 means there's roughly a 75% chance it's accurate, highlighting the need for robust error handling and potentially alternative input methods when tracking is unreliable.

You are reviewing a PR that uses the SCNSceneKit framework to render a complex 3D model. The reviewer comments: 'This is using a very high level of detail – are you sure the device can handle this with the current battery life?' What does the reviewer likely mean by 'high level of detail'?
When discussing 3D rendering in Vision Pro, high level of detail refers to the complexity of the model – specifically, a large number of vertices, textures, and potentially complex shaders. These elements demand substantial processing power from the device, leading to increased battery consumption if not carefully managed; Option A is too narrow, while options C and D misinterpret the meaning of 'detail' in this context.

During a design discussion for a new Vision Pro app feature, a UX designer suggests using TapGesture for user interaction. Another developer asks: 'How do we ensure this gesture is recognized even when the user's hands are partially obscured?'
Vision Pro's hand tracking system is central to enabling robust gesture recognition even with partial occlusion. By leveraging hand tracking data alongside a TapGesture, the app can accurately detect taps based on the dominant hand's position and movement – this allows for reliable interaction even when fingers are partially hidden. Option A is incorrect; Options C and D misrepresent the integration between hand tracking and tap gestures.

This exercise, "Vision Pro Development Vocabulary", tests your understanding of wearables & spatial computing language vocabulary and phrasing through 10 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 10 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.
