iPhone UI Design Considerations

 The iPhone is not a desktop system.

 The Apple iPhone is a powerful smart phone that is
being used to improve the productivity of user. To
design simple, successful iPhone app user interfaces,
keep in mind the unique attributes of the iPhone.

 Eat with it, sleep with it, drink with it, live with it.

3



 Small Screen
 Limit the number of controls

 Break a single complex app into two or more
apps with very different functions.

4



 One screen at a time

5



 One app at a time(iOS < 4)
 Save user-entered data immediately.

 Show the saved data the next time users
open the app.

6



 Hand/Finger Input
 UI Elements must be big enough to hit with a
finger.

 Finger tapping means the pointer can just
disappear. Rollover effects don’t work well.

 Multi-touch events

7



 No External Keyboard
 No physical keyboard on iPhone.

 On-screen keyboard appears when needed.

 Multi keyboard types are available.

 Device Orientation

9



 Device Orientation
 Applications are notified when device rotates portrait to landscape and
back.

 Can also find absolute orientation.

10



 No training
The strongest asset of the iPhone is its ease of use. The simple user
interface usually allows users to get their tasks done without training or
reading online Help.

Analyze your users, their needs and design a very simple, intuitive user
interface that allows users to operate your app without training or Help
