Abstract

Disclosed is a method and an apparatus, as well as a computer program, for associating digitizer tablet stroke samples with entries in an electronic personal information management (PIM) tool, such as an electronic organizer or an electronic calendar. A stroke database has a plurality of time stamped stroke entries, and a PIM database has a plurality of entries each having a time associated therewith. A controller searches at least one of the stroke database and the PIM database to locate corresponding entries in each database that indicate that a particular one of the stroke entries was created at a time that corresponds to a particular one of the PIM database entries. The controller is responsive to the search being successful for forming a link between the stroke entry and the PIM database entry for enabling corresponding stroke information to be visualized in association with the particular one of the PIM database entries. In accordance with these teachings, and by example, a user is enabled to recall and view handwritten notes and other information that were made during a meeting that corresponds to an entry within the organizer database.

Claims

1. A method for associating an output of an electronic tablet with entries of an electronic personal information management tool, comprising steps of:

storing the output of the electronic tablet into a tablet database, the stored output being time stamped to indicate a time when the output was created; and

for a particular entry of the electronic personal information management tool, the entry having a time associated therewith, searching the tablet database to locate any stored output of the electronic tablet that is time stamped with a time that indicates that the electronic tablet generated output during the time associated with the entry and, if the search is successful, forming a link between the particular entry and the stored output of the electronic tablet.

2. A method as in claim 1, and further comprising a step of invoking a viewer to visualize the stored output of the electronic tablet, to which the link has been formed.

3. A method as in claim 1, wherein the step of searching the tablet database searches for a time stamp having a time that lies within a range of times associated with the entry.

4. A method as in claim 1, wherein the range of times extends before and after a time associated with the entry.

5. A method as in claim 1, wherein the range of times extends before and after a time period associated with the entry.

6. A method as in claim 1, wherein the range of times extends at least one of before and after a time period associated with the entry.

7. A method as in claim 2, wherein the step of invoking the viewer is executed by the link pointing to the viewer.

8. A method as in claim 2, wherein the step of invoking the viewer is executed by first invoking a file that is associated with the entry, the file calling the viewer.

9. A method as in claim 1, and further comprising a step of periodically updating links between entries and the stored output of the electronic tablet.

10. A method as in claim 9, wherein the step of updating is executed in response to at least one predetermined criterion being met.

11. A method as in claim 10, wherein the at least one predetermined criterion step is an arrival of new output from the electronic tablet.

12. A method as in claim 10, wherein the at least one predetermined criterion step is an arrival of a predetermined amount of new output from the electronic tablet.

13. A method as in claim 9, wherein the step of updating is executed as a background process.

14. A method for associating an output of an electronic tablet with entries of an electronic personal information management tool, comprising steps of:

storing the output of the electronic tablet into a tablet database as a tablet entry, each tablet entry being time stamped to indicate a time when the output was created; and

for a particular tablet entry, searching a database of entries of the electronic personal information management tool, each entry having a time associated therewith, to locate an entry having a time that corresponds to the time stamp of the tablet entry and, if the search is successful, forming a link between the tablet entry and the entry having a time that corresponds to the time stamp of the tablet entry.

15. A method as in claim 14, and further comprising a step of periodically updating links between tablet entries and the entries of the electronic personal information management tool.

16. A method as in claim 15, wherein the step of updating is executed in response to at least one predetermined criterion being met.

17. A method as in claim 16, wherein the at least one predetermined criterion step is an arrival of new output from the electronic tablet.

18. A method as in claim 16, wherein the at least one predetermined criterion step is an arrival of a predetermined amount of new output from the electronic tablet.

19. A method as in claim 15, wherein the step of updating is executed as a background process.

20. Apparatus for associating digitizer tablet stroke samples with entries of an electronic personal information management (PIM) tool, comprising a stroke database having a plurality of time stamped stroke entries, a PIM database having a plurality of entries each having a time associated therewith, and a controller for searching at least one of the stroke database and the PIM database to locate corresponding entries in each database that indicate that a particular one of the stroke entries was created at a time that corresponds to a particular one of the PIM database entries, said controller being responsive to the search being successful for forming a link between the stroke entry and the PIM database entry for enabling corresponding stroke information to be visualized in association with the particular one of the PIM database entries.

21. A computer program embodied on a computer-readable medium, said program comprising code segments for associating digitizer tablet stroke samples with entries of an electronic personal information management (PIM) tool, wherein a stroke database has a plurality of time stamped stroke entries and a PIM database has a plurality of entries each having a time associated therewith, wherein at least one of said code segments searches at least one of the stroke database and the PIM database to locate corresponding entries in each database that indicate that a particular one of the stroke entries was created at a time that corresponds to a particular one of the PIM database entries, and wherein at least one other one of said code segments searches is responsive to the search being successful for forming a link between the stroke entry and the PIM database entry for enabling corresponding stroke information to be visualized in association with the particular one of the PIM database entries.
