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.

8



Device Orientation

9



Device Orientation

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

Can also find absolute orientation.

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
