User interface with auditory feedback for hand-held device

摘要

A hand-held information processing device has a thumb wheel (112) that lets the user scan a circular array of selectable audio-items displayable in a menu. Each one of the audio-items is represented by an audible click (110) that confirms progress along the menu of selectable audio-items when the wheel is turned a notch up or down. This enables the user to select an audio-item with one hand and without having to look at the device. It also allows for a form factor smaller than that of a conventional hand-held device since a keypad is not needed for entering digits to select an audio item.
