iPod a history – design
71iPod’s success can be attributed to many factors, but one of the most significant factors is fabulous design. Its small, portable design with revolutionary menu navigation and never before seen white earbuds made this gadget a household name synonymous with mp3 players.
The design of the menu and the invention of the click wheel reinvented scrolling through the menu. The menu itself is hierarchical and the music is categorized in ways we usually categorize music: by artist, genre, album, etc. For the first time in any mp3 player Apple introduced the capability to create personal playlists which made scrolling through the music more flexible. But without the click wheel this would be unpractical. Up to that point all similar devices had buttons, and to get from one song to the next user had to push the button. This type of navigation was extremely complicated. This is seen most profoundly when user has a couple of hundred songs on the mp3 player and wants to scroll through his collection. The click wheel controls are designed so they can be operated with the thumb while the iPod is carried with the remaining four fingers. This allows single-handed operation. The click wheel is the central input device and almost all the user input goes through this singular control. The third generation iPod moved the play/pause, menu, and track forward and backward controls to separate buttons below the screen, which was changed back in the later generations. The click wheel has many functions: navigating menus, navigating within a track, volume control, rating songs to name a few.
The simplicity of design made iPod a fashion item, and the ease of use established the trust with the users with these two factors Apple just had to wait for the iPod to become the success it is today.
