1. A method of navigating a list on a handheld device, comprising steps of:
- displaying a first portion of the list;
moving through further portions of the list, at a first coarse interval from each preceding portion, until a desired section of the list is located; and
moving through said further portions of the list by a second finer interval to permit a user to locate a desired list entry, wherein the further portions are displayed in response to user actuation of an input device in a first dimension, said input device being one of either a scroll key or thumbwheel, and wherein the second finer interval is set in response to user actuation of the input device in a second dimension orthogonal to the first dimension.

Abstract
A method and system that permits a user to navigate or browse a long list on a handheld device with a restricted user interface, such as a limited display and a limited user input device. The user first uses a coarse search to find a generally desired area in the list. The user then uses finer and finer search intervals in the vicinity of the desired area, until the desired entry is located.

6. A system for navigating a list on a handheld device;
- comprising;
a display limited to displaying a portion of the list; an input device limited to movement in two dimensions; and a navigation engine, responsive to user actuation of the input device and coupled to an information source for storing the list, having; an information presentation component for retrieving portions of the list from the information source and displaying the portions of the list on the display, a coarse interval component for moving through the list at a first coarse interval to display further portions of the list, said moving being responsive to user actuation of said input device in a first dimension and a fine interval component activated in response to user actuation of the input device in a second dimension orthogonal to the first dimension for moving through the list at a second finer interval responsive to user actuation of said input device in said first dimension after locating a desired section of the list at the coarse interval, wherein the input device is one of either a scroll key or a thumbwheel. - View Dependent Claims (7, 8, 9, 10)
