Abstract:
1. A method comprising: superimposing a viewing window on a page of information at a first position within the page of information, wherein: in response to a user's manipulation of an input tool, moving the viewing window relative to the page of information from the first position within the page of information to a second position within the page of information, thereby causing the viewing window to display a second subset of the page of information located at the second position; tracking a motion of the input tool when moving the viewing window relative to the page of information from the first position to the second position; comparing the tracked motion of the input tool to a threshold; determining whether the tracked motion of the input tool exceeds the threshold based on comparison results; in response to a determination that the tracked motion of the input tool does not exceed the threshold and movement of the viewing window has stopped at the second position, snapping back the viewing window from the second position within the page of information to the first position within the page of information, thereby causing the viewing window to display the first subset of the page of information located at the first position; and in response to a determination that the tracked motion of the input tool does exceed the threshold and movement of the viewing window has stopped at the second position, maintaining the viewing window at the second position within the page of information.
