Visual: Covers blindness, low vision, poor eyesight, and color blindness.
Motor/Mobility: Includes difficulties using hands, tremors, muscle control issues.
Auditory: Encompasses deafness and hearing impairments.
Seizures: Refers to epilepsy triggered by visual strobes or flashing effects.
Cognitive and Intellectual: Spans developmental disabilities, learning difficulties (like dyslexia), and cognitive disabilities (PTSD, Alzheimer's) affecting memory, attention, problem-solving, etc.
Expanded View of Disability: Accessibility isn't limited to specific disabilities but extends to temporary and situational limitations, like a broken wrist or sun glare affecting vision.
Why Accessibility Matters:
Social and Ethics: Accessibility is a civil right recognized by the UN, impacting dignity, autonomy, participation, and equal opportunity. Not accessible = discrimination.
Legal Reasons: Laws globally enforce accessibility for websites and applications to prevent discrimination.
Business Impact: Inaccessible systems miss out on a significant market segment, with people with disabilities constituting a substantial consumer base. Lawsuits for lack of accessibility are costly, and remediation expenses are inevitable.
