Accessibility
Accessibility means designing interfaces that can be used by people with different abilities, contexts, devices, and needs.
Accessibility is also about autonomy. A product is more accessible when people can complete their goals independently, using their own device settings, strategies, and Assistive Technology when needed.
UI Concerns
- readable contrast
- keyboard navigation
- clear labels
- focus states
- semantic structure
- predictable interaction
- text alternatives
- error messages
- captions and transcripts
- target size
- clear heading hierarchy
- no color-only information
- understandable form feedback
Design Mindset
Accessibility is not only a checklist at the end.
It should affect layout, interaction, writing, hierarchy, and component states from the beginning.
In UID 07, Marianna Cerato frames accessibility as a framework, not an outcome. Disability can be permanent, temporary, or situational. A sunny screen, tired attention, one hand occupied, low memory, or a noisy environment can all change how a person can use an interface.
Standards And Testing
- WCAG gives a practical framework for accessible web content.
- Accessibility Testing combines automated checks with manual and user testing.
- Cognitive Accessibility focuses on reducing memory, attention, and comprehension barriers.
Automated tools help find issues, but they cannot replace testing with real people.
In Design Systems
Accessibility becomes easier to maintain when it is built into:
- Design Tokens
- component states
- form patterns
- focus indicators
- documentation
- handoff annotations
- QA checklists
If the system components are accessible from the start, product teams do not need to rediscover the same accessibility decisions on every screen.
AI and Accessibility
AI can support accessibility work, but it does not replace accessibility knowledge or testing.
Designers still need to verify the final experience.
