Abstract

A system and method for dynamically generating a textual description for a visual data representation is provided. The method accesses a data set and visual template associated with a visual data representation. A textual description template is also accessed. The visual template is interpreted using the textual description template and data from the data set. As the visual template is interpreted, a textual description is generated corresponding to the visual data representation. The system and method may be initiated by a user request or a command based on some other event such as the passage of time, a change to data in the data set, or the like. The textual description may be generated dynamically in response to a request or previous to, and in anticipation of, a request from a user.

5. The method of claim 1, wherein the textual description comprises text in one of a plurality of human-readable languages.

6. The method of claim 1, wherein the textual description is a formatted tabular representation of the data set.

7. The method of claim 1, further comprising:

receiving a request to generate a textual description for the visual data representation.

8. The method of claim 7, wherein the request is automatically generated.

9. The method of claim 7, wherein the request originates from a user, the method further comprising:

sending the generated textual description over a network to the user.

10. The method of claim 7, wherein the request comprises a data set, a visual template, and a textual description template.

11. The method of claim 1, wherein at least one of the data set, the visual template, and the textual description template are accessed through a different data source.

12. The method of claim 1, wherein at least one of the data set, the visual template, and the textual description template are modified programmatically.

13. The method of claim 1, wherein the textual description template is associated with a plurality of visual templates.

14. The method of claim 1, wherein a language identifier is accessed to identify the language for the textual description and wherein the textual description template comprises text elements associated with the identified language.

15. The method of claim 1, wherein the data set and visual template are integrated within a single XML data structure.

16. The method of claim 13, wherein the textual description template comprises an XML data structure.

17. The method of claim 1, wherein the textual description comprises plain text.

18. The method of claim 1, wherein the textual description comprises formatted text.

19. The method of claim 1, wherein the textual description comprises machine-readable textual code.

20. The method of claim 1, further comprising:

displaying the textual description to a user.

21. The method of claim 20, wherein displaying comprises:

displaying the visual data representation in a first window; and

displaying the textual description in a second window on a common display device.

22. A system for dynamically generating a textual description for a computer-generated visual data representation, the system comprising:

a memory comprising a data set corresponding to the computer-generated visual data representation, a visual template associated with the computer-generated visual data representation and a textual description template, wherein the visual template comprises information about a visual characteristic of the computer-generated visual data representation;

an interpreter in communication with the memory, interpreting a visual element of the visual template and identifying a text element within the textual description template, the text element corresponding to the visual element;

a generator in communication with the interpreter for generating a textual description element which incorporates data from the data set based on the text element;

an assembler in communication with the generator for assembling one or more text description elements into a textual description, wherein the textual description describes the visual characteristic of the computer-generated visual data representation, and wherein the textual description comprises visual semantic information available within the computer-generated visual data representation.

23. The system of claim 22, wherein the visual element comprises a visual interactive element for allowing a user to interact with the visual data representation and wherein the generated textual description element comprises a textual interactive element for providing substantially the same interactive functionality within the textual description as the visual interactive element.

24. The system of claim 22, further comprising:

an interface component which receives a request to generate a textual description for the visual data representation.

25. The system of claim 24, wherein the request originates from a user and the interface component sends the generated textual description over a network to the user.

26. The system of claim 24, wherein the request is automatically generated.

27. The system of claim 24, wherein the request comprises one of the data set, the visual template, and the textual description template.

28. The system of claim 24, wherein the request comprises one or more parameters which identify a source for at least one of the data set, the visual template, and the textual description template.
