Abstract

The present invention teaches a variety of methods and systems for providing computer/human interfaces. According to one method, the user interfaces with an electronic device such as a computer system by engaging a sensor with desired regions of an encoded physical medium. The encoded physical medium is preferably chosen to provide intuitive meaning to the user, and is thus an improved metaphor for interfacing with the computer system. Suitable examples of the encoded physical medium include a data-linked book, magazine, globe, or article of clothing. Some or all of the selected regions have had certain information encoded therein, information suitable for interfacing and controlling the computer system. When the user engages the sensor with a region having certain encoded information, the certain encoded information is interpreted and an appropriate action taken. For example, the sensor or the computer system may provide suitable feedback to the user. The encoded physical medium may have text and/or graphic illustrations that draw the user in or provide meaningful clues or instructions perhaps related to the encoded information. The sensor may have at least one identification number (ID) providing information such as user identity, sensor type, access type, or language type. The sensor can transmit the certain decoded information together with the at least one ID to the computer system.

Claims

1. A method for generating an encoded physical medium having a region wherein content has been encoded, the method comprising the steps of:

receiving content that is to be encoded into a desired location on the encoded physical medium;

encoding the content according to a particular encoding scheme suitable for application onto the encoded physical medium; and

inserting the encoded content and a marker into a corresponding desired location within a representation of the encoded physical medium, the marker indicating that the content is encoded within the corresponding desired location,

wherein at least one of the marker and encoded content has at least one portion being outside of the visible electro magnetic spectrum range.

4. A method as recited in claim 1, wherein the content includes a uniform resource locator (URL).

5. A method as recited in claim 4, wherein the URL points to a registration web site wherein the user can register.

6. A method as recited in claim 4, wherein the URL points to a transaction web site.

7. A method as recited in claim 1, wherein the content is encoded using a spectral encoding scheme.

8. A method as recited in claim 7, wherein the spectral encoding scheme visually blends together with a portion of text and graphics present on the physical medium.

9. A method as recited in claim 7, wherein the spectral encoding scheme results in the encoded content being hidden from a user of the encoded physical medium.

2. A method for generating an encoded physical medium having a region wherein content has been encoded, the method comprising the steps of:

receiving content that is to be encoded into a desired location on the encoded physical medium; and

inserting the encoded content and a marker into a corresponding desired location of the encoded physical medium, the marker indicating that the content is encoded within the corresponding desired location,

wherein at least one of the marker and encoded content has at least one portion being outside of the visible electro magnetic spectrum range.

10. A method as recited in claim 2, wherein the content includes a uniform resource locator (URL).

11. A method as recited in claim 10, wherein the URL points to a registration web site wherein the user can register.

12. A method as recited in claim 10, wherein the URL points to a transaction web site.

13. A method as recited in claim 2, wherein the content is encoded using a spectral encoding scheme.

14. A method as recited in claim 13, wherein the spectral encoding scheme visually blends together with a portion of text and graphics present on the physical medium.

15. A method as recited in claim 13, wherein the spectral encoding scheme results in the encoded content being hidden from a user of the encoded physical medium.

3. An encoded physical medium suitable for use in interfacing a user and a computer system, the encoded physical medium including a region wherein certain information is encoded, the certain encoded information including a marker indicating that the certain encoded information is encoded in the first region, the certain encoded information including data suitable for interpreting into computer readable data, wherein at least one of the marker and encoded content has at least one portion being outside of the visible electro magnetic spectrum range.

16. An encoded physical medium as recited in claim 3, wherein the certain encoded information includes a uniform resource locator (URL).

17. An encoded physical medium as recited in claim 16, wherein the URL points to a registration web site wherein the user can register.

18. An encoded physical medium as recited in claim 16, wherein the URL points to a transaction web site.

19. An encoded physical medium as recited in claim 3, wherein the certain encoded information is encoded using a spectral encoding scheme.

20. An encoded physical medium as recited in claim 19, wherein the spectral encoding scheme visually blends together with a portion of text and graphics present on the physical medium.
