Spatial UI

Distributes information and interaction in a three-dimensional environment.

Status in 2026: Active. In current use.
Trend 2027 to 2030: Rising in some contexts (an editorial projection, not a forecast).
The term: Community or market label, or a descriptive term.

Definition

Distributes information and interaction in a three-dimensional environment.

Traits

volumes
layers
spatial focus

Typical settings: XR, CAD, Collaboration.

When to use it, and when not

Consider it when the task and motivation match: professionals who work with 3D objects. Typical settings: xr, cad, collaboration.

Be careful when the risk below would hurt the main task: excessive depth and confusion.

The audience is a hypothesis

"Professionals who work with 3D objects" describes a motivation, task or context for which this direction tends to be chosen. It was not measured, and it says nothing about any age, gender or other group.

UX risk and how to reduce it

Risk: Excessive depth and confusion.

Mitigation and accessibility: Use the z-axis when it has semantic value.

How to check: Test a prototype against a plain baseline on a real task: completion, time, errors, comprehension, accessibility and preference, segmented by context rather than by stereotype.

Evidence

Indirect: the sources support underlying principles, not a preference for this style.

The sources below support the principles that apply to this term. None of them shows that this style works better or is preferred.

Apple 2025 (Standard or guideline): Layout for spatial computing.
W3C Web Accessibility Initiative 2023 (Standard or guideline): Accessibility requirements.

Heuristic scales

Relative editorial judgements from 1 to 5. They are not results of a study and not a measure of quality.

Visual complexity heuristic: 4 / 5 (1 is few visual elements, 5 is many layered elements)
Expressiveness heuristic: 3 / 5 (1 is restrained, neutral, 5 is highly expressive)
Information density heuristic: 4 / 5 (1 is sparse, 5 is dense)

In our library

No design-style recipe in @codeatlasdev/ui implements this term yet. You can still build it from the --ca-* tokens: see Theming.

Prompt for your AI

Paste this into a coding agent. It carries the trade-offs, and asks for a baseline to compare against.

Design this interface in the "Spatial UI" direction (aesthetic, spatial): Distributes information and interaction in a three-dimensional environment.
Visual and interaction traits to use: volumes, layers, spatial focus.
Main UX risk: Excessive depth and confusion. Mitigate it: Use the z-axis when it has semantic value.
Keep it accessible to WCAG 2.2 AA: contrast, visible focus, keyboard operation, 24 px minimum targets, reflow at 320 CSS px and reduced motion.
Keep the content, hierarchy and behavior the same as a plain baseline so the two can be compared. Do not claim the style performs better; the choice should be validated with users.

Limits

The atlas is a broad, living catalogue, not every style that exists. No authority enumerates them, and the classes (movement, aesthetic, design system, layout, pattern, principle) overlap.
The 1 to 5 scores are relative editorial judgements. They are not results of a study and not a measure of quality.
An audience is a hypothesis about motivation, task and context. It was never measured and says nothing about any age, gender or other group.
The sources support underlying principles (visual complexity, legibility, grouping, accessibility, platform conventions). None shows that a particular style works better or is preferred.
The 2027 to 2030 trend is an editorial projection, not a forecast.
Terms in the Future / AI category rest on exploratory work, some of it preprints, with no causal validation.

Supports: Platform guidance for Apple Vision Pro: field of view is the space a person can see without moving their head, and depth is conveyed with cues such as distance, occlusion and shadow.
Does not support: Layout for flat screens, or evidence of outcomes. It is device-specific platform guidance.

Supports: What conformant content must do, as testable success criteria with a level (A, AA, AAA): for example 1.4.10 Reflow (no two-dimensional scrolling at a width equivalent to 320 CSS pixels, except content that needs two-dimensional layout), 2.4.11 Focus Not Obscured (Minimum) and 2.5.8 Target Size (Minimum) (at least 24 by 24 CSS pixels, with listed exceptions).
Does not support: What users prefer or what performs better. A standard says what is required, not what is popular.
