BACKGROUND
5
[0001) Portable media devices may be adapted to store and play a variety of file types such music files, video files and photo files on displays attached to the device or to remote devices, such as stereos, television, etc. As uses of these devices increase, the ability to usefully provide information on the display becomes more challenging. Accordingly, changing the orientation of what is displayed has been one way to provide more useful information. However, by changing the orientation of what is to be displayed, the entire device itself has to be rotated to properly view the display. Accordingly, input fields on the device also move orientation, leading to confusion as to what fiinctions the input fields perform when the device is rotated.
Summary
[0002] When a portable media device is rotated, confusion may resuh as to the function of input fields on the device as the input fields rotate with the device. An approach to address the confusion is to assign or map functions to input fields based on an orientation indicarion where the orientafion indication provides the desired orientaUon of the media to be displayed. The orientation indicarion may be provided by the media, may be provided by an orientafion indicator in the device or may be selected by a user. As a result of the method, a user may always know that by pressing an input field in particular locadon. such as the input field to the right of the center point of the input fields on the device, the .same function will occur no matter what the orientation of the device.
