Abstract

A method includes generating, for a page comprising a plurality of elements, a contextual grouping of at least one of the plurality of elements based on an object model of the page. A method includes generating a user interface for a non-sighted user based on a page, the user interface comprising at least one contextual grouping generated based on an object model of the page. A method includes identifying a page to be analyzed, the page based on a document object model (DOM) and having a plurality of elements configured to be visually arranged when the page is generated for display. The method includes processing the identified page based on the DOM to include each of the plurality of elements in at least one contextual group associated with the page. The method includes facilitating navigation of the page by a non-sighted user using the at least one contextual group.

Claims

1. A method comprising:

generating, for a page comprising a plurality of elements, a contextual grouping of at least one of the plurality of elements based on an object model of the page.

2. The method of claim 1, further comprising recording the generated contextual grouping such that it is associated with the page.

3. The method of claim 2, further comprising using the recorded contextual grouping to provide navigation of the page to aid a non-sighted user.

4. The method of claim 1, wherein the object model is a document object model.

5. The method of claim 1, wherein generating the contextual grouping comprises:

processing the page in a first pass based on the object model to determine a plurality of groups comprising the plurality of elements; and

processing the determined plurality of groups in a second pass to determine whether to combine any of the determined groups into the contextual grouping.

6. The method of claim 5, wherein processing the page in the first pass comprises creating a running directional sense as each element is processed, the directional sense representing a difference in horizontal and vertical position of a previously processed element relative to a currently processed object.

7. The method of claim 5, wherein the processing in the first pass is performed using at least a first rule and the processing in the second pass is performed using at least a second rule.

8. The method of claim 7, wherein the first rule uses a length of a string included in the element being processed.

9. The method of claim 7, wherein the first rule uses a width or height of the element being processed.

10. The method of claim 7, wherein the first rule uses whether the element being processed is a link or header object in the object model.

11. The method of claim 7, wherein the first rule uses whether the element being processed visually touches another of the plurality of elements.

12. The method of claim 7, wherein the first rule uses how many of the plurality of elements are in one of the plurality of groups that has been determined.

13. The method of claim 7, wherein the first rule uses a directional sense of the element being processed another of the plurality of elements.

14. The method of claim 7, wherein the second rule uses a distance in at least one of horizontal and vertical direction from the element being processed to another of the plurality of elements.

15. The method of claim 7, wherein the second rule uses a size of at least one of the plurality of groups from the first pass.

16. The method of claim 7, wherein the second rule uses an intersection between one of the plurality of groups currently processed with another of the plurality of groups.

17. A method comprising:

generating a user interface for a non-sighted user based on a page, the user interface comprising at least one contextual grouping generated based on an object model of the page.

18. The method of claim 17, wherein generating the user interface provides that the non-sighted user can skip at least one entire region of the page without visiting each of the elements in the region.

19. A method comprising:

identifying a page to be analyzed, the page based on a document object model (DOM) and having a plurality of elements configured to be visually arranged when the page is generated for display;

processing the identified page based on the DOM to include each of the plurality of elements in at least one contextual group associated with the page; and

facilitating navigation of the page by a non-sighted user using the at least one contextual group.

20. The method of claim 19, wherein including each of the plurality of elements in the at least one contextual group comprises:

processing the page in a first pass based on the object model to determine a plurality of groups comprising the plurality of elements, the processing in the first pass is performed using at least a first rule; and

processing the determined plurality of groups in a second pass to determine whether to combine any of the determined groups into the contextual grouping, the processing in the second pass is performed using at least a second rule.
