How Can I Help?

VISION AND HEARING

13

• Avoid font sizes smaller than 16 pixels (depending of course on device, viewing distance, line height etc.)

• Let people adjust text size themselves

• Pay particular attention to contrast ratios with text.

• Avoid blue for important interface elements.

• Provide subtitles when video or audio content is fundamental to the user experience

MOTOR CONTROL

14

• 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
