Design #1

Description

This design allows quick access to the functions supported by the music player. The number keypad becomes the controls when the music player is on.

Advantages

• Require the least number of button presses
• Easy to keep track of applied settings (random, repeat, volume)

Disadvantages

• Might take some time to get used to the buttons

Design #2 (PREFERRED)

I prefer this design to the other two. I can adjust the settings (random, repeat, volume) quickly by pressing the left/right buttons and scrolling the jog dial. The status icons are informative.

Description

This interface displays all the controls and settings directly on the screen.

Advantages

• Descriptive icons
• Easy to adjust settings

Disadvantages

• Require more button presses

Design #3

Description

This design takes advantage of the left/right buttons to navigate between the song and settings screens.

Advantages

• Easy to adjust settings

Disadvantages

• Hard to know and/or keep track of what settings (random, repeat, volume) are applied
• The number keypad can be confusing when used between screens
