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.

14. The method of claim 1 wherein comparing the user motion of the input tool to the threshold includes comparing the user motion of the input tool to a user-defined threshold.

15. The method of claim 1 wherein comparing the user motion of the input tool to the threshold includes comparing the user motion of the input tool to a system-defined threshold.

16. The method of claim 1 wherein the page of information includes at least one column of information and constraining the position of the page of information on the display includes constraining the position of the column of information on the display.

17. The method of claim 16 wherein constraining the position of the page of information on the display includes constraining the horizontal position of the column of information on the display.

18. The method of claim 17 wherein:

the column of information includes a logical column; and

constraining the position of the page of information on the display includes constraining the horizontal position of the logical column on the display.

19. A method of navigating on a display, the method comprising:

tracking motion of a stylus on a display;

comparing a component of motion of the stylus on the display in one direction to a threshold; and

correcting a position of a page of information on the display if the motion in the one direction does not exceed the threshold.

20. The method of claim 19 wherein the component of motion comprises horizontal motion, the one direction comprises a horizontal direction, and correcting the position of the page comprises correcting a horizontal position of the page.

21. The method of claim 20 wherein the page of information includes at least one column of information such that correcting the horizontal position of the page of information on the display includes correcting the horizontal position of the column of information on the display.

22. The method of claim 21 wherein the first column of information includes a logical column having a width not exceeding a width of the display such that correcting the original horizontal position includes correcting the original horizontal position of the logical column on the display.

23. The method of claim 19 wherein the component of motion comprises vertical motion, the one direction comprises a vertical direction, and correcting the position of the page comprises correcting a vertical position of the page.
