User interface

iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods (except the iPod shuffle and iPod touch) have five buttons and the later generations have the buttons integrated into the click wheel—an innovation that gives an uncluttered, minimalist interface. The buttons perform basic functions such as play, next track, and previous track. Other operations such as scrolling through menu items and controlling the volume are performed by using the click wheel in a rotational manner. The iPod shuffle does not have a click wheel and instead has five buttons positioned differently from the larger models. The iPod Touch has no click-wheel. Instead it uses a 3.5 touch screen in addition to a home button, sleep/wake button and (on the second generation iPod touch) volume up and down buttons. The user interface for the iPod touch is virtually identical to the iPhone. Both devices use the iPhone OS.
