This document discusses 10+1 interaction principles for mobile UI design: 1. Learnability - The interface should be easy to use for first-time users. 2. Efficiency - Key tasks should be optimized to be as efficient as possible. 3. Memorability - Frequency of use impacts memorability; consistent design helps users remember. 4. Error recovery - Users should not be allowed to make mistakes; feedback prevents errors. 5. Simplicity - Avoid unnecessary functionality; keep visual design clean and minimal. 6. Mapping - What users expect to happen matches actual interactions. 7. Visibility - Understand user goals and make all interactive elements visible and identifiable. 8. Feedback -

 Define User Group (UX methods)
 10+1interaction principles on mobile UI

5. The mobile user(移動用戶)

6. The mobile user(移動用戶)
Anxiety

7. The mobile user(移動用戶)

8. The mobile user(移動用戶)
Personalization

9. 1st: Find your target user

10. Define User Group (UX methods)
 Find an average profile (qualitative or quantitative methods)
AVERAGE
PROFILE

11. Define User Group (UX methods)
用户在实
验室进行语 用户访谈后进行
音便签评估 功能介面拼贴
用户进行14天的日志记录，
将每次記事軟件的心得记录
下来（总共53笔日志，手机
记事约占25笔）。
UED团队针对功
能介面和用户需

求，输出概念版
户进行回访验证，

12. Define User Group (UX methods)
 Find an average profile ( web analysis, UX methods)

15. Principle 1:Learnability
 Easy to use from the first time

16. Principle 2:Efficiency (cont’d)
 Key tasks should be mad as efficient as possible
n steps
Depth(d): number of levels
Breadth(b):number of options per menu panel

17. Principle 2:Efficiency (cont’d)
 Key tasks should be mad as efficient as possible

18. Principle 2:Efficiency
 Key tasks should be mad as efficient as possible
Auto-suggest search process optimized with Tap-Ahead

19. Principle 3:Memorability
 Frequency of use is the key factor in memorability
Header
Title
Content Top (Action bar)
Content
Context Menu & Tool bar

20. Principle 4: Error Recovery
 Users should never be allowed to make a mistake
Dialogs are for:
1.Inform message
2.Force to confirm an action
3.Rigister form
Toast messages can be trigger by an action user takes

21. Principle 5:Simplicity
 Avoid necessary functionality and keep the visual design cleanness
Large size Small size
Icons is resized but same area Keep all 3 stories are display on smaller size
Images are scaled Stylistic element is removed on smaller device
Future area

22. Principle 6:Mapping
 What the users expect to happen is exactly what should happen
Drag and drop (gestures)

23. Principle 7:Visibility
 Understnading the user’s goals
Touch targets
Button size 36x36 px (apples
(30 px~44px by fingers touch)
suggested 44px)

24. Principle 8:feedback
 User should always be in control

25. Principle 9:Consistency

26. Principle 10:Flexibility(cont’d)
Show/Hide

27. Principle 10:Flexibility(cont’d)
Show/Hide
Firefox

28. Principle 10:Flexibility(cont’d)
Show/Hide

29. Principle 10:Flexibility
Stretch
Utilize 9-patches

30. Principle 10+1:Satisfaction
 How much the user enjoys or dislikes your product
User Satisfaction?
Pleasure to design
