Abstract
Navigating on a display includes tracking motion of an input tool on a display, comparing a motion of the input tool to a threshold, and changing a position of the visible portion of a page of information on the display if the input tool motion exceeds the threshold. The position of the visible portion of the page of information on the display is constrained if the motion does not exceed the threshold.

A method comprising:
- superimposing a viewing window on a page of information, wherein:
- the page of information is larger than the viewing window;
- and
- the viewing window reveals only a subset of the page of information;
- moving the viewing window relative to the page of information in response to a user's manipulation of an input tool;
- tracking a motion of the input tool when moving the viewing window relative to the page of information;
- comparing the motion of the input tool to a threshold;
- determining whether the motion of the input tool exceeds the threshold;
- and
- snapping back the viewing window to an original position if it is determined that the motion of the input tool does not exceed the threshold.
