Abstract

A method and apparatus for locating items on a physical document and a method for creating a geographical link from an electronic document to the physical document. The geographical link is created by encoding, in a geographic link to the physical document, geographic coordinates of a referenced item in the electronic document. The electronic document is not derived from the physical document. Locating items on the physical document includes calibrating an opto-touch foil that is aligned on the physical document, including processing a calibration location included in locations appearing in the physical document and referred to in the electronic document. For each location, foil coordinates of the opto-touch foil corresponding to where each location appears in the physical document are computed utilizing geographic coordinates of each location and a generated calibration relationship between the geographic coordinates of the calibration location and calibration foil coordinates of the opto-touch foil.

Claims

1. A method of creating a geographic link from an electronic document to a physical document for locating, on the physical document, an item referenced in the electronic document, comprising the steps of:

defining the referenced item in the electronic document, said electronic document not being derived from the physical document;

determining geographic coordinates of the referenced item;

defining the geographic link to the physical document; and

encoding the geographic coordinates in the geographic link.

2. The method of claim 1, wherein the step of encoding further includes the step of encoding an address of a second electronic document in the geographic link.

3. The method of claim 2, wherein the address of the second electronic document is a Uniform Resource Locator address of a web server hosting the second electronic document.

4. The method of claim 1, further including the step of storing the geographic coordinates in a table.

5. The method of claim 1, further including the step of:

computing foil coordinates on an opto-touch foil from the geographic coordinates of the referenced item and a calibration relationship, said opto-touch foil being aligned on the physical document, said calibration relationship being between geographic coordinates of a selected calibration location and calibration foil coordinates of the selected calibration location on the opto-touch foil, said selected calibration point having been selected from the electronic document and said opto-touch foil having been selectively touched or pressed at a position corresponding to where the calibration location appears in the physical document.

6. The method of claim 5, further including the step of storing the foil coordinates and the geographic coordinates in a table.

7. The method of claim 5, wherein the opto-foil comprises a touch foil and a transparent light emitting foil such that the touch foil is adapted to being directly touched or pressed and the light emitting foil is disposed between the touch foil and the physical document.

8. The method of claim 1, wherein the physical document includes a map.

9. The method of claim 1, wherein:

the electronic document is a hyper text markup language document; and

the geographic link uses syntactic conventions of hyper text markup language.

10. The method of claim 1, wherein the geographic coordinates include longitude and latitude.

11. A method of locating items appearing on a physical document, comprising the steps of:

calibrating an opto-touch foil that is aligned on the physical document, said calibrating comprising processing a calibration location comprised by a plurality of locations appearing in the physical document and being referred to in an electronic document, said electronic document not being derived from the physical document, each location of the plurality of locations having geographical coordinates, said processing generating a calibration relationship between the geographic coordinates of the calibration location and calibration foil coordinates of the opto-touch foil, said calibration foil coordinates corresponding to where the calibration location appears in the physical document; and

for each location of the plurality of locations, computing foil coordinates of the opto-touch foil corresponding to where each location appears in the physical document, said computing utilizing the geographic coordinates of each location and the calibration relationship.

12. The method of claim 11, further including the steps of:

storing in a table for each location of the plurality of locations;

an identifier of each location, the geographic coordinates of each location, and the foil coordinate of each location.

13. The method of claim 11, further including the step of sending the computed foil coordinates to the opto-touch foil to cause illumination of positions upon the opto-touch foil corresponding to where each location of the plurality of locations appears in the physical document.

14. The method of claim 11, further including the steps of:

responsive to a first location of the plurality of locations being selected in the electronic document, sending the foil coordinates of the first location to the opto-touch foil to cause blinking of light at a first position upon the opto-touch foil corresponding to where the first location appears in the physical document.

15. The method of claim 12, further comprising storing an address of a second electronic document in the table.

16. The electronic document of claim 15, wherein the address of the second electronic document is a Uniform Resource Locator address of a web server hosting the second electronic document.
