Common Disabilities

Visual Disabilities

Blindness: Support screen readers with semantic HTML, ARIA labels, and descriptive alt text.
Low Vision: Use high-contrast colors, resizable text, and scalable layouts.
Color Blindness: Avoid conveying information through color alone; use patterns, labels, or icons.

Hearing Disabilities

Deaf or Hard of Hearing: Provide captions for videos, transcripts for audio, and visual alternatives to sound notifications.

Motor Disabilities

Limited Mobility (e.g., Parkinson’s, Arthritis): Ensure full keyboard navigation, large clickable targets, and alternative input methods like voice or switch controls.

Cognitive & Learning Disabilities

Dyslexia: Use clear fonts (e.g., sans-serif), simple language, and adjustable text spacing.
ADHD & Memory Impairment: Maintain consistent layouts, minimize distractions, and provide focus aids like highlighted active elements.

Speech Disabilities

Aphasia, Muteness: Provide text-based alternatives for voice interactions, such as chat or button controls.

Best Practices for Accessible UX Design

Follow WCAG (Web Content Accessibility Guidelines) standards.
Use ARIA (Accessible Rich Internet Applications) attributes appropriately.
Conduct user testing with assistive technology (screen readers, voice commands).

Accessibility Testing

Accessibility testing ensures digital products are usable for people with disabilities. It involves checking compliance with WCAG (Web Content Accessibility Guidelines) and testing with assistive technologies like screen readers, keyboard navigation, and voice controls.

Key Accessibility Testing Methods

Automated Testing: Use tools like Axe, WAVE, or Lighthouse to detect issues.
Manual Testing: Navigate using only a keyboard, test color contrast, and check alternative text.
Assistive Technology Testing: Ensure compatibility with screen readers (NVDA, VoiceOver) and other assistive tools.
User Testing with Disabled Users: Gather real feedback to improve usability.
