A hand-held information processing device, such as a mobile phone, has a thumb wheel that lets the user scan a circular array of options. Each respective one of the options is represented by a respective audio output that gets played out when the wheel is turned a notch up or down. This enables the user to select an option with one hand and without having to look at the device. It also allows for a form factor smaller than that of a conventional mobile phones since a keypad is not needed for entering digits to make a call from a personalized directory.

A method of navigating through television programs is disclosed. A television receiver displays a mosaic image with sub-images representing the available programs. The receiver further receives an electronic program guide with program descriptions. Upon activating a &ldquo;theme&rdquo; button ( ), the viewer can enter a desired program type, e.g. &ldquo;movie&rdquo;. In response thereto, the brightness of the sub-images representing programs that are not desired is reduced. The user is thus assisted in navigating through programs he is interested in, while maintaining the mosaic structure he is familiar with, and without losing the association between channels and their positions on the mosaic screen.
