Interface One
Plain and simple interface
Advantages
- Clean main menu interface; appealing to the eye; not cluttered
- Navigation is simple; does not use keypad
- Navigation requires only top half of cell phone
- Sub-menus are easy to understand and follow the clean and simple theme
- Items are clearly labeled
Disadvantages
- Cannot select specific time in song for manual scan; only in 30 sec. intervals
- Buttons for rewind/fast forward and manual scan do too many things; pressing mechanism may be confusing or easy to do incorrectly
- Music library is only organized in alpha-order by song title; no other sorting options
Interface Two
Close up of huge body of text
Menu always visible on interface.
Advantages
- User can clearly see menu options at all times; menu easily accessible through any sub-screen
- Clean interface
- Items clearly labeled
- Navigation uses minimal buttons; only makes use of top half, no keypad use
- Can manual scan to specific time in song
Disadvantages
- Some users may find always-visible menu distracting.
- Only small space of screen allotted for song info and song playing status
- Music library is only organized in alpha-order by song title; no other sorting options
- Many things to note regarding the jog dial and how it controls options on the screen
Interface Three
All options visible on one screen; no sub-screens
Advantages
- All options on one screen
- Easy access to any of the options
- Repeat, Manual Scan and Shuffle toggled/customized by simply clicking a number (for each) on the keypad; no need for scrolling to find it first then clicking to toggle/customize
- Can manual scan to specific time in song
- Displays icon for Play/Pause status
Disadvantages
- Makes use of many buttons - top half of cell phone and keypad
- All options on one screen means minimized icons (i.e. volume control has turned into an icon rather than a full page)
- No music library - can't see current music collection; can only shift through them with next/prev buttons
Personal Choice
I personally like Interface One. I like the clean look the main song screen has. Even though I can't manual scan to a specific time in the song, I don't mind because this is a function I would rarely use. I like how the sub-menus pop-up at the bottom of the screen and leave the song title and artist visible. Furthermore, I really like how I can view the songs in my music library (unlike in Interface Three).
