USER EXPERIENCE

4. User Experience
All the aspects of how people use an interactive
product: the way it feels in their hands, how well they
understand how it works, how they feel about it while
they’re using it, how well it serves their purposes, and
how well it fits into the entire context in which they are
using it.

5. “App users have a big app appetite, downloading
about 10 apps per month on average, but they rarely
use these apps frequently or for long.”
Josh Clark “Tapworthy: Designing Great iPhone Apps”

8. THINGS TO REMEMBER

9. IDENTIFY YOUR CUSTOMERS
Who is your target audience?

10. THINK ABOUT THE CONTEXT OF USE
A mobile device can be used at anytime, anywhere.
Context affects the interaction between the people
and the interface.

WTF?

14. KEEP IT SIMPLE
If your UI requires instructions - it’s badly designed.

15. 80/20
Generally, 80% of app users will use just
20% of its functionality.

16. LESS IS MORE
Identify the single, most important task to your app.
AND MAKE IT DEAD SIMPLE.

17. KEEP IT SAFE
Default buttons in alert boxes should
favor the safest option*
CANCEL DELETE ALL

18. MAKE IT BRIEF AND CLEAR
Keep alerts brief and clear, explain them what
happened and what they can do next.

19. Role-Playing the Interaction by Stephen Anderson (http://www.youtube.com/watch?v=hkAFdIrTR00)

20. USE DESIGN PATTERNS
Follow conventions and patterns to reduce the
learning curve and to make the experience more
intuitive.

22. “When it comes to mobile forms,
be brutally efficient and trim, trim, trim.”
— Luke Wroblewski, “Mobile First” (2011)

23. DESIGN FOR TOUCH
Areas of interaction shouldn’t be smaller than 44pt.
Smaller elements = bigger distance between them.

24. DESIGN FOR TOUCH
Place most important
actions in “thumb zone”

25. CONSIDER ORIENTATION
Consider both portrait
and landscape
orientations while
designing an interface.

26. YOUR ICON IS YOUR BUSINESS CARD
“Make your icon colorful, make it memorable, make it fun, but whatever
you do, don’t make it mysterious. The app icon is fundamentally an
advertisement, and like any good ad, it has to be clear what it’s selling.”

27. WHAT’S WRONG WITH THESE DOORS?

28. AFFORDANCE
Design aspect of an object
which suggest how the object
should be used; a visual clue
to its function and use.

29. DESIGN FOR EFFICIENCY
Enable people to navigate to the most important
content and functionality in as few steps as possible.

30. ♥ DESIGN FOR EMOTION ♥
“It is not enough that we build products that function,
that are understandable and usable, we also need to
build products that bring joy and excitement,
pleasure and fun, and, yes, beauty to people’s lives.”
— Don Norman

31. Customers care about their problems -
not your solution.
— Dave McClure
