Zooming Controller
First Claim
1. A method for accessing a data field in a data processing system, the method comprising:
- when the data processing system is in a first mode;
scrolling a region of a scrollable user interface in response to input from a touch input device, wherein a portion of the user interface within the window is displayed on a display device;
receiving a signal to enter into a second mode;
when the data processing system is in the second mode;
remapping control of the touch input device to control both a scale and a range, the scale and the range specifying a portion of the data field for access;
adjusting the scale if the touch input device detects motion along a first axis;
adjusting the range if the touch input device detects motion along a second axis.

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. In one embodiment of the present invention, a particular piece of data within the broad data field can be accessed. First, the scale is selectively varied, thereby controlling a range within the data field. Then, the range is moved to encompass portions of the data field in which the piece of data resides. Next, the scale is successively decreased while, simultaneously, points successively closer to the location are kept with the range. The scale is decreased (i.e., increasing the range'"'"'s resolution) and the range is moved in this manner until the piece of data is actually accessed.

15. An apparatus for accessing a data field in a data processing system, the apparatus comprising:
-
means for determining when the data processing system is in a first mode; when the data processing system is in the first mode; means for scrolling a region of a scrollable user interface in response to input from a touch input means, wherein a portion of the user interface within the window is displayed on a display means; means for receiving a signal to enter into a second mode; means for determining when the data processing system is in the second mode; when the data processing system is in the second mode; means for remapping control of the touch input means to control both a scale and a range, the scale and the range specifying a portion of the data field for access; means for adjusting the scale if the touch input means detects motion along a first axis; means for adjusting the range if the touch input means detects motion along a second axis. - View Dependent Claims (16, 17, 18, 19, 20, 21)
