# Low-Stimulation UI DS159. Interaction principle: Inclusion. Page: https://ui.codeatlas.com.br/atlas/low-stimulation-ui/. Index: https://ui.codeatlas.com.br/llms/atlas.txt Minimizes unnecessary animation, notifications and saturation. - Status in 2026: Active. In current use. - Trend 2027 to 2030: Rising (an editorial projection, not a forecast). - The term: Known technical term or standard. ## Traits - restrained color - visual quiet Typical settings: Health, productivity. ## When to use it, and when not Consider it when the task and motivation match: users sensitive to stimuli or concentrating. Typical settings: health, productivity. Be careful when the risk below would hurt the main task: important alerts become too subtle. Audience (a hypothesis about motivation and task, never measured, not a statement about any group): Users sensitive to stimuli or concentrating. ## UX risk and how to reduce it - Risk: Important alerts become too subtle. - Mitigation and accessibility: Urgency levels and preferences. - 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 support the principles that apply to this term. None shows that this style works better or is preferred. - [E09] W3C Web Accessibility Initiative (2023). Understanding Success Criterion 2.3.3: Animation from Interactions. https://www.w3.org/WAI/WCAG22/Understanding/animation-from-interactions (Standard or guideline). Does not support: A prevalence figure, or that all animation is harmful. Essential motion is excepted, and the criterion is above the AA level most programs target. - [E08] W3C Web Accessibility Initiative (2021). WCAG 2 supplemental guidance. https://www.w3.org/WAI/WCAG2/supplemental/ (Standard or guideline). Does not support: Normative requirements: supplemental guidance is advisory, not required for conformance. This page is an index; a specific recommendation needs the linked document. ## 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. Last reviewed 2026-10-25. ## Heuristic scales Relative editorial judgements from 1 to 5, not results of a study. - Visual complexity: 1 / 5 (heuristic) - Expressiveness: 1 / 5 (heuristic) - Information density: 2 / 5 (heuristic) ## In our library No design-style recipe implements this term yet; build it from `--ca-*` tokens. ## Prompt for your AI ```text Design this interface in the "Low-Stimulation UI" direction (interaction principle, inclusion): Minimizes unnecessary animation, notifications and saturation. Visual and interaction traits to use: restrained color, visual quiet. Main UX risk: Important alerts become too subtle. Mitigate it: Urgency levels and preferences. 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. ```
