• Avoid font sizes smaller than 16 pixels (depending of course on device, viewing distance, line height etc.)
• Let people adjust text size themselves

• Avoid blue for important interface elements.
• Provide subtitles when video or audio content is fundamental to the user experience
MOTOR CONTROL

• Buttons on touch interfaces should be at least 9.6 millimeters diagonally (for example, 44 × 44 pixels on an iPad) for ages up to 70, and larger for older people.
LIFE STAGE
15
• Beware of content or functionality that implicitly assumes someone is young or at a certain stage in life
EXPERIENCE WITH TECH
16
• Don’t make assumptions about prior knowledge
• Interrogate all parts of your design for usability, even the parts you didn’t create
COGNITION
17
• Introduce product features gradually over time to prevent cognitive overload
• Avoid Changing key flows drastically
• Avoid splitting tasks across multiple screens if they require memory of previous actions
• During longer tasks, give clear feedback on progress and reminders of goals
• Provide reminders and alerts as cues for habitual actions
ATTENTION
18
• Don’t be afraid of long-form text and deep content.
• Allow for greater time intervals in interactions (for example, server timeouts, inactivity warnings)
• Avoid dividing users’ attention between multiple tasks or parts of the screen
