Lesson 7: Accessibility and Inclusive Design

Accessibility ensures people with disabilities can use software. Key concerns: visual, auditory, motor, and cognitive impairments. For example, color-blind users need sufficient color contrast and should not rely on color alone to convey meaning. Screen-reader users need proper labels (alt text for images). Filipino designers must also consider users with limited literacy: using clear icons and voice prompts can help. Universal Design extends accessibility to all users, e.g. using larger clickable areas (good for users with tremors or big fingers). The HCI curriculum covers standards like WCAG (Web Content Accessibility Guidelines).

Think about older adults: they may prefer simpler layouts, larger fonts, and clear language. For instance, when designing a health-monitoring app for elderly Filipinos, you'd use high-contrast, large text, and avoid jargon. For users with hearing impairment, ensure any multimedia has captions. For Philippine public systems (like an online gov't form), typical accommodations include skip links (for keyboard navigation) and forms that allow keyboard input. HCI courses often include case studies or tools like colorblind simulators to raise awareness. The goal is to make interfaces usable by everyone.
