Abstract

A system and method for identifying captured written data associated with a writing surface using a pen-based computing system are described. In one embodiment, a series of writing surfaces, such as notebooks, are produced, each including a plurality of pages that have an encoded pattern. In an embodiment, each writing surface is also associated with an identifier recognizable by a smart pen or other data capture device. When the smart pen captures written data from a writing surface, the smart pen determines whether the pen-based computing system includes stored written data previously captured from a writing surface having the same encoded pattern as the writing surface from which written data is currently being captured.

Claims

1. A smart pen device for distinguishing captured data from a source of the captured data comprising:

a processor;

a gesture capture system coupled to the processor for capturing written data in relation to an encoded pattern on a writing surface from which the written data is captured;

an onboard memory coupled to the processor and configured to store the written data captured by the gesture capture system;

computer program code stored on a memory and configured to be executed by the processor, the computer program code including instructions for;

receiving an input to archive the first written data,

decoupling the first written data from the encoded pattern to remove an association between the first written data and the encoded pattern on the writing surface from which the first written data was captured,

storing the first written data in a memory, and

capturing a second written data coupled to the encoded pattern associated to the writing surface.

2. The device of claim 1, wherein the computer program code further includes instructions for:

receiving a second written data coupled to the encoded pattern associated to the writing surface, the second written data unrelated to the first written data; and

storing the second written data in the onboard memory without modifying the stored first written data.

3. The device of claim 1, wherein the computer program code further includes instructions for:

receiving an identifier associated with a writing surface from the gesture capture system;

determining a encoded pattern associated with the received identifier;

determining whether previously captured written data stored in the onboard memory is associated with the encoded pattern associated with the received identifier; and

responsive to determining previously captured written data stored in the onboard memory is associated with the encoded pattern associated with the received identifier, generating a request to archive the previously captured written data stored in the onboard memory.

4. The device of claim 3, wherein the computer program code further includes instructions for:

receiving an input in response to the request to archive the previously captured written data stored in the onboard memory;

disassociating the previously captured written data stored in the onboard memory from the encoded pattern associated with the written identifier; and

storing the previously captured written data independent from the encoded pattern associated with the written identifier in the onboard memory.

5. The device of claim 3, wherein the onboard memory includes a binary value associated with the identifier, the binary value indicating whether the onboard memory includes written data associated with the identifier.

6. A method for associating a source with data captured by a pen-based computing system, comprising:

receiving an identifier associated with a writing surface from a gesture capture system included on a smart pen;

determining a encoded pattern associated with the received identifier;

determining whether previously captured written data is associated with the encoded pattern associated with the received identifier; and

responsive to determining that the previously captured written data is associated with the encoded pattern associated with the received identifier, generating a request to archive the previously captured written data.

7. The method of claim 6, further comprising:

receiving an input in response to the request to archive the previously captured written data stored in the onboard memory responsive to the input;

disassociating the previously captured written data from the encoded pattern associated with the written identifier; and

storing the previously captured written data independent from the encoded pattern associated with the written identifier in an onboard memory of the smart pen.

8. The method of claim 6, wherein determining whether previously captured written data is associated with the encoded pattern associated with the received identifier comprises:

determining whether the onboard memory of the smart pen includes previously captured written data associated with the encoded pattern associated with the received identifier; and

responsive to determining the onboard memory of the smart pen includes previously captured written data associated with the encoded pattern, determining whether the previously captured written data is active.

9. The method of claim 6, further comprising:

capturing additional written data from the writing surface associated with the received identifier via a gesture capture system of the smart pen; and

storing the additional written data in the onboard memory of the smart pen and an association between the additional written data and the encoded pattern associated with the received identifier.

10. The method of claim 6, wherein receiving the identifier associated with the writing surface from the gesture capture system included on the smart pen comprises:

scanning a sticker affixed to the writing surface using the gesture capture system.

11. The method of claim 6, wherein receiving the identifier associated with the writing surface from the gesture capture system included on the smart pen comprises:

scanning a predefined portion of the writing surface using the gesture capture system.

12. The method of claim 11, wherein scanning the predefined portion of the writing surface using the gesture capture system comprises:

scanning a component of the writing surface encoded with the encoded pattern using the gesture capture system; and

analyzing the encoded pattern.

13. A method for distinguishing data captured by a pen-based computing system from a source of the captured data, comprising:

receiving, from a smart pen, a first written data coupled to an encoded pattern associated with a writing surface from which the written data is captured;

storing the first written data in a memory associated with the smart pen;

receiving an input to archive the first written data; and

decoupling the first written data from the encoded pattern by separating the first written data from the encoded pattern associated with the writing surface.

14. The method of claim 13, further comprising:

receiving, from the smart pen, a second written data coupled to the encoded pattern associated to the writing surface, the second written data unrelated to the first written data; and

storing the second written data in the memory associated with the smart pen without modifying the stored first written data.

15. The method of claim 13, wherein decoupling the first written data from the encoded pattern comprises:

separating the first written data from the encoded pattern associated with the writing surface; and

transmitting the first written data from memory associated with the smart pen to a computing system.
