Patent application 2003/0095096 is for improved approaches for users of computing devices to interact with graphical user interfaces. According to one aspect, a rotational user action supplied by a user at a user input device is transformed into linear action with respect to a graphical user interface. According to another aspect, a portion of an extended list of items is displayed by a graphical user interface and, through rotational user actions at a user input device, the portion of the list being displayed can be varied with welcomed ease of use. Although the type of computing device can vary, the improved approaches are particularly well-suited for use with a portable media player.

A patent is a grant from a patent office, such as the United States Patent Office. "Patent Pending" is a phrase that an application for a patent has been filed and is in some stage in the process of obtaining a patent. Thus, a patent can be presently enforced while a patent that is merely pending is unenforceable but can mature into a patent that can be enforced. Once the pending patent matures, the patent owner can sue for back damages or reasonable royalties starting from the filing date of the patent.
