We are moving to smaller and smaller devices and optimising our products for them. But in this process forgetting about a host of people who cant use those products at all. By: Shashank Kapoor

1. Leaving a World Behind!

2. IT is a young industry

more time to complete a task than adults
younger than 30

6. Over a quarter of adults in Developed countries
will be 55 or older

12. How Can I Help?

13. 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

14. 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.

15. LIFE STAGE
15
• Beware of content or functionality that implicitly assumes someone is young or at a certain
stage in life

16. 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

17. 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

18. 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

19. “Changing the World”
“Making people’s life easier”
