Abstract

A handheld device has a display for presenting an image to a user, a processor electrically connected to the display, memory electrically connected to the processor, and an input panel electrically connected to the processor. The input panel has a number of keys for generating key signals, and a zoom control device for generating a zoom control signal. The display is used to present both text and iconic information to the user. A display program, held in the memory, will change the font size of displayed text or icons according to the zoom control signal. When doing so, the display program selects a proper amount of text or icons to be displayed within the boundary of the display, and arranges the selected text or icons within the display.
