1. In a computer system, a method of navigating within a set of data items, comprising:
- displaying a user interface on a display device comprising a scale and an identifier of a current position along the scale, wherein the scale corresponds to a range including at least a subset of the data items;
receiving user input indicating movement;
responsive to an indication of movement along a first axis or a second axis, controlling a position of a cursor on the display device;
responsive to the indication of movement along the first axis, changing the scale, wherein the scale corresponds to a resolution of the range, such that a change in the scale corresponds to a change in the resolution of the range, wherein changing the scale comprises remapping the user input indicating movement along the first axis to control the change in the scale; and
responsive to the indication of movement along the second axis, changing the current position along the scale, wherein changing the current position along the scale comprises remapping the user input indicating movement along the second axis to control the change in the current position along the scale.

Abstract
A method and device for accessing a broad data field having a fine resolution. The user selects a scale which can be varied. The scale controls a range within the data field. By moving the range to encompass different portions of the data field, the user can scan that portion of the data field. The present invention allows the user to simultaneously select the scale while moving the range over different portions of the data field. Thus, the user can “zoom in” and “zoom out” of different portions of the data field.

24. A computer program product of navigating within a set of data items, comprising:
-
a computer readable medium; and computer program code, encoded on the medium, for controlling a processor to perform the operations of; displaying a user interface on a display device, the user interface comprising a scale and an identifier of a current position along the scale, wherein the scale corresponds to a range including at least a subset of the data items; receiving user input indicating movement; responsive to an indication of movement along a first axis or a second axis, controlling a position of a cursor on the display device; responsive to the indication of movement along the first axis, changing the scale, wherein the scale corresponds to a resolution of the range, such that a change in the scale corresponds to a change in the resolution of the range, wherein changing the scale comprises remapping the user input indicating movement along the first axis to control the change in the scale; and responsive to the indication of movement along the second axis, changing the current position along the scale, wherein changing the current position along the scale comprises remapping the user input indicating movement along the second axis to control the change in the current position along the scale. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
