Abstract

An identification system includes several sheets formed of digital paper each having a unique identifier on a writing surface thereof. Each digital paper may have a form printed on the writing surface. Data representing the form and the location thereof relative to the writing surface is stored in a computer. A digital pen connectable to the computer is compatible with the digital paper for recording pen strokes made by the digital pen and the location of the pen strokes relative to the writing surface. The digital pen includes an ink dispensing tip for marking the writing surface according to the pen strokes. The computer is connectable to the digital pen for retrieving and storing the data representing the pen strokes for each sheet. Upon completion of a form, the computer compares the data representing the pen strokes with the form data and determines the user input to the form.

Claims

1. A digital paper identification system comprising:

a processor having a memory coupled thereto;

a plurality of sheets, each sheet including digital paper having a writing surface and a unique identifier formed thereon;

a digital pen for communicating with the processor, the digital pen compatible with the digital paper for recording pen strokes made by the digital pen and the location thereof relative to the writing surface of the digital paper, the digital pen including an ink dispensing tip for marking the writing surface of the digital paper according to the pen strokes;

the unique identifier including at least one pattern corresponding to an identifiable cell of a master sheet of the digital paper such that data representing the unique identifier is recordable via the digital pen;

the digital pen for sensing and recording data representing the unique identifier and the pen strokes formed on each of the sheets; and

the processor configured for communicating with the digital pen for retrieving from the digital pen the data representing the unique identifier and the pen strokes formed on each of the sheets and including means for storing the unique identifier and the corresponding pen strokes data for each sheet in the memory, and for processing the data representing the pen strokes for each sheet.

2. The system according to claim 1 further comprising a monitor coupled to the processor and configured to display an electronic image of the sheet.

3. The system according to claim 2 wherein the processor is configured for generating and displaying on the monitor an electronic image of the sheet in real time while the sheet is being marked upon.

4. A digital paper identification system comprising:

a processor having a memory and a monitor coupled thereto;

a plurality of sheets, each sheet including digital paper having a writing surface and a unique identifier formed thereon, each sheet having a form printed on the writing surface for completion by a user;

form data corresponding to each sheet and representing the form and the location thereof relative to the writing surface being stored in the memory;

a digital pen connectable to the processor, the digital pen compatible with the digital paper for recording pen strokes made by the digital pen and the location thereof relative to the writing surface of the digital paper, the digital pen including an ink dispensing tip for marking the writing surface of the paper according to the pen strokes;

the unique identifier including at least one pattern corresponding to an identifiable cell of a master sheet of the digital paper such that data representing the unique identifier is recordable via the digital pen;

the digital pen for sensing and recording the unique identifier and the pen strokes formed on each of the sheets; and

means for generating and displaying on the monitor an electronic image of the sheet including the pen strokes created by a user employing the digital pen and retrieved by the processor.

5. The system according to claim 4 wherein the processor is configured to store data representing the electronic image of each sheet in accordance with the unique identifier associated with the sheet.

6. The system according to claim 4 wherein the digital paper includes a plurality of dots disposed in a pre-defined pattern throughout the writing surface thereof.

7. The system according to claim 4 further comprising means for selecting the identifiable cell of the master sheet from a plurality of cells each having a different pattern relative to each other.

8. The system according to claim 7 wherein the means for selecting the identifiable cell includes randomly selecting the identifiable cell of the master sheet.

9. The system according to claim 4 wherein the unique identifier includes at least one pattern corresponding to an identifiable cell of each of an ordered series of master sheets of the digital paper.

10. The system according to claim 7 wherein the unique identifier is associated with a cell number corresponding to the identifiable cell of the master sheet.

11. The system according to claim 4 wherein the processor is configured for determining user selections marked on one of the sheets while the sheet is being marked upon, and for comparing the pen strokes and the location thereof recorded by the digital pen with the form data corresponding to the sheet.

12. The system according to claim 4 wherein each of the sheets includes a form pre-printed on the digital paper including at least one of a unique identifier.

13. The system according to claim 4 wherein each sheet defines an accept area on the writing surface where a user can indicate acceptance of a completed form by marking the accept area using the digital pen.

14. The system according to claim 13 wherein the processor is configured to record and store data representing an image of a completed form along with the time and date of the acceptance thereof and the unique identifier associated with the completed form.

15. The system according to claim 4 wherein the processor is configured to generate and display at least one of an electronic image of the sheet and a verification screen identifying user written ink strokes on the sheet.

16. A sheet for receiving written information, comprising:

a sheet of digital paper having a writing surface for being written on by a digital pen;

a unique identifier formed on the sheet of digital paper; and

the unique identifier including at least one pattern corresponding to an identifiable cell of a master sheet of the digital paper such that data representing the unique identifier is to be recordable via a digital pen.

17. The sheet according to claim 16 wherein the pattern associated with the unique identifier is comparable to a pattern associated with the master sheet of digital paper.

18. The sheet according to claim 16 wherein the unique identifier comprises a series of patterns each corresponding to identifiable cells of the master sheet of digital paper.

19. The sheet according to claim 16 wherein the unique identifier is imprinted on the sheet of digital paper.

20. A sheet for receiving written information, comprising:

a sheet of digital paper having a writing surface for being written on by a digital pen;

a unique identifier cell printed on the sheet of digital paper; and

the unique identifier cell including at least one pattern corresponding to an identifiable cell of a master sheet of the digital paper such that data representing the unique identifier cell is to be recordable via a digital pen.

21. The sheet according to claim 20 wherein the pattern associated with the unique identifier cell is comparable to a pattern associated with the master sheet of digital paper.

22. The sheet according to claim 20 wherein the unique identifier cell comprises a series of patterns each corresponding to identifiable cells of the master sheet of digital paper.

23. The sheet according to claim 20 wherein the unique identifier cell is imprinted on the sheet of digital paper.

24. The sheet according to claim 20 wherein the unique identifier cell is associated with a command on processing of ink stroke data on the digital paper.

25. The sheet according to claim 24 wherein the command is to delete an ink stroke for a predetermined area on the digital paper as marked by the digital pen.

26. The sheet according to claim 24 wherein the command is to resume accepting ink strokes on the digital paper.
