Abstract

A method and apparatus for use with an electronic display system including a display surface wherein the system is capable of identifying a touch location on at least a portion of the display surface of a contact with the display surface, the display surface having a display area, the method for moving a cursor icon about at least a portion of the display area and comprising the steps of identifying first and second areas within the display area having first and second area surfaces, respectively, sensing a touch location on the first area surface and presenting a cursor icon on the second area surface as a function of the touch location on the first area surface.

Claims

1. A method for use with an electronic display system including a display surface wherein the system is capable of identifying a touch location on at least a portion of the display surface of a contact with the display surface, the display surface having a display area, the method for moving a cursor icon about at least a portion of the display area and comprising the steps of:

identifying first and second areas within the display area having first and second area surfaces, respectively;

sensing a touch location on the first area surface; and

presenting a cursor icon on the second area surface as a function of the touch location on the first area surface.

2. The method of claim 1 wherein the first and second areas are distinct.

3. The method of claim 2 wherein the step of identifying the second area includes the step of providing a border to distinguish the second area from other areas on the display surface.

4. The method of claim 1 wherein the step of identifying the first and second areas includes identifying a first area that is smaller than the second area.

5. The method of claim 4 wherein the step of identifying the first and second areas further includes identifying an area along an edge of the display area as the first area.

6. The method of claim 1 wherein the shape of the first area is similar to the shape of the second area and the first area is smaller than the second area.

7. The method of claim 6 wherein the step of presenting a cursor icon on the second area surface as a function of the touch location on the first area surface includes presenting the cursor icon at a location such that the position of the cursor icon relative to the second area is identical to the position of the touch location relative to the first area.

8. The method of claim 7 wherein, when contact is made with the first area surface and the touch location is moved on the first area surface, the cursor icon is moved on the second area surface.

9. The method of claim 1 wherein, when contact is made with the first area surface and the touch location is moved on the first area surface along a first direction, the cursor icon is moved on the second area surface along a second direction where the second direction is identical to the first direction.

10. The method of claim 1 wherein the first area surface includes a plurality of first area surfaces useable to control activity on the second area surface.

11. The method of claim 1 wherein the first area surface is a section of the second area surface.

12. The method of claim 1 wherein the step of identifying first and second areas includes presenting a border indicating the second area onto the display surface.

13. The method of claim 12 further including identifying a buffer area that includes the second area and a border around the second area and, wherein, the method further includes the step of sensing touch location within the buffer area and the second area and presenting the cursor onto the surface at the absolute position of the touch location when he surface in one of the buffer area and the second area is contacted.

14. The method of claim 13 wherein the step of presenting a cursor icon on the second area surface as a function of the touch location on the first area surface includes presenting the cursor icon at a location such that the position of the cursor icon relative to the second area is identical to the position of the touch location relative to the first area.

15. The method of claim 1 wherein the first area includes every part of the display surface except the second area.

16. The method of claim 15 wherein the step of presenting a cursor icon in the second area as a function of the touch location on the first area includes identifying movement of the touch location the first area and causing relative movement of the cursor on the second area.

17. The method of claim 16 also including the steps of sensing touch location on the second area surface and presenting a cursor icon on the second area surface as a function of the location of the touch on the second area surface.

18. The method of claim 17 wherein the step of presenting a cursor icon on the second area surface as a function of the location of the touch on the second area surface includes presenting the cursor at the absolute position of the touch on the second area surface.

19. The method of claim 1 wherein the step of presenting a cursor icon on the second area include projecting the cursor icon on the second area.

20. The method of claim 1 for use with an instrument for interacting with the display surface, the step of identifying touch location including identifying the location of the instrument on the first area surface.

21. A method for use with an electronic display system including a display surface wherein the system is capable of identifying a touch location on at least a portion of the display surface of a contact with the display surface, the display surface having a display area, the method for moving a cursor icon about at least a portion of the display area and comprising the steps of:

identifying first and second areas within the display area having first and second area surfaces, respectively;

when the first area surface is contacted at a first touch location;

a) sensing the touch location on the first area surface;

b) presenting a cursor icon on the second area surface as a function of the touch location on the first area surface; and

when the second area surface is contacted at a second touch location;

a) sensing the second touch location on the second area surface; and

b) presenting a cursor icon on the second area surface at the second touch location on the second area surface.

22. The method of claim 21 wherein the first and second areas are distinct.

23. The method of claim 21 wherein the shape of the first area is similar to the shape of the second area and the first area is smaller than the second area.

24. The method of claim 21 wherein, when the contact is made in the first area surface and the touch location is moved on the first area surface, the cursor icon is moved on the second area surface.

25. An electronic display apparatus comprising:

a display including a display surface, the display surface including first and second areas within the display area having first and second area surfaces, respectively;

a sensor for identifying a touch location on at least a portion of the display surface when contact is made with the display surface;

a processor programmed to perform the steps of;

sensing a touch location on the first area surface; and

presenting a cursor icon on the second area surface as a function of the touch location on the first area surface.

26. The display apparatus of claim 25 wherein the first and second areas are distinct.

27. The display apparatus of claim 25 wherein the first area is smaller than the second area.

28. The display apparatus of claim 25 wherein the first area includes an area along an edge of the display area.

29. The display apparatus of claim 25 wherein the step of presenting a cursor icon on the second area surface as a function of the touch location on the first area surface includes presenting the cursor icon at a location such that the position of the cursor icon relative to the second area is identical to the position of the touch location relative to the first area.

30. The display apparatus of claim 25 wherein a buffer area includes the second area and a border around the second area and, wherein, the method further includes the step of sensing touch location within the buffer area and presenting the cursor onto the surface at the absolute position of the touch location when the surface in the buffer area is contacted.
