Abstract

A device stores one or more compression rules for an action language. Upon receipt of a signal from a tag (such as an RFID tag, a visual tag, or an audio tag), a compressed data stream corresponding to the tag is decoded from the signal. Based on the one or more compression rules, one or more action parameters are derived from the compressed data stream. With these parameters, a corresponding action is performed. The action may include communicating across a wireless communications network as well as obtaining content from a remote content provider. Also the action may include storing data, such as a contact entry, or a calendar event.

Claims

1. A method, comprising:

(a) storing one or more compression rules for an action language;

(b) receiving a signal from a tag;

(c) decoding from the signal a compressed data stream corresponding to the tag;

(d) based on the one or more compression rules, deriving one or more action parameters from the compressed data stream; and

(e) performing an action based on the one or more action parameters.

2. The method of claim 1, wherein the one or more compression rules includes at least one of:

using short identifiers, storing data in a compact format, using fixed data structures, and using references.

3. The method of claim 1, wherein step (f) comprises communicating across a wireless communications network.

4. The method of claim 1, wherein step (f) further comprises obtaining content from a remote content provider.

5. The method of claim 1, wherein step (f) includes storing a contact entry.

6. The method of claim 1, wherein step (f) includes storing a calendar event.

7. The method of claim 1, wherein the tag is a radio frequency identification (RFID) tag.

8. The method of claim 1, wherein the tag is a visual tag.

9. The method of claim 1, wherein the tag is an audio tag.

10. A wireless communications device, comprising:

a tag reader configured to receive a signal from a tag and decode a compressed data stream from the signal;

a memory configured to store one or more compression rules for an action language;

an action interpreter configured to derive one or more action parameters from the compressed data stream based on the one or more compression rules, and

an application configured to perform an action in accordance with the one or more action parameters.

11. The method of claim 10, wherein the one or more compression rules includes at least one of:

using short identifiers, storing data in a compact format, using fixed data structures, and using references.

12. The wireless communications device of claim 10, wherein the tag reader is configured to receive the signal from a radio frequency identification (RFID) tag.

13. The wireless communications device of claim 10, wherein the tag reader is configured to receive the signal from a visual tag.

14. The wireless communications device of claim 13, wherein the tag reader comprises a camera.

15. The wireless communications device of claim 10, wherein the tag reader is configured to receive the signal from an audio tag.

16. The wireless communications device of claim 10, wherein the application is a personal contacts application, and the action includes storing a contact entry.

17. The wireless communications device of claim 10, wherein the application is a calendar application, and the action includes storing a calendar event.

18. The wireless communications device of claim 10, wherein the application is a browser application, and the action includes obtaining content from a remote content provider.

19. The wireless communications device of claim 10, wherein the action includes communicating across a wireless communications network.

20. A computer program product comprising a computer readable memory device having computer program logic recorded thereon for enabling a processor in a computer system of a wireless communications device, the computer program logic comprising:

program code for enabling the processor to store one or more compression rules for an action language;

storing the compact representation in a tag to enable parsing the compact format using stored compression rules for the action language to identify actions and related fields and parameters.

21. A method, comprising:

(a) storing a plurality of action language specifications, each action language specification having one or more compression rules;

(b) receiving a signal from a tag;

(c) decoding from the signal a compressed data stream corresponding to the tag, the compressed data stream including an action language specifier;

(d) selecting among the stored action language specifications, an action language specification corresponding to the action language specifier;

(e) deriving one or more action parameters from the compressed data stream based on the selected action language specifications corresponding to the action language specifier; and

(f) performing an action based on the one or more action parameters.

22. A method, comprising:

encoding an action into a compact representation according to an action language, wherein the action language employs one or more of using short identifiers, storing data in a compact format, using fixed data structures, and using references;

storing the compact representation in a tag to enable parsing the compact format using stored compression rules for the action language to identify actions and related fields and parameters.

23. An apparatus, comprising:

an encoder for encoding an action into a compact representation according to an action language, wherein the action language employs one or more of using short identifiers, storing data in a compact format, using fixed data structures, and using references; and

a generator for storing the compact representation in a tag to enable parsing the compact format using stored compression rules for the language to identify actions and related fields and parameters.

24. The apparatus of claim 23, further comprising a memory that stores one or more action language specifications.

25. A tag, comprising:

a computer readable memory device;

a compact representation in said computer readable memory device, of an action according to an action language;

wherein the compact representation employs one or more of using short identifiers, storing data in a compact format, using fixed data structures, and using references to enable parsing the compact format using stored compression rules for the action language to identify actions and related fields an parameters.
