Abstract

A method and article of manufacture of making dynamic content more accessible to screen readers and web spiders. The method applies to a server connected to a client via a network. The method includes receiving from the client an action event indicative of an action performed by a user on content displayed on the client and a change event indicative of a change in the content. The method further includes generating metadata for improving accessibility to the content based on the action event and the change event.

Claims

1. A method for application to a server connected with a client via a network, the method comprising the steps of:

receiving from the client an action event indicative of an action performed by a user on content displayed on the client and a change event indicative of a change in the content; and

generating metadata for improving accessibility to the content based on the action event and the change event.

2. The method according to claim 1, wherein the change event occurs in response to the action event.

3. The method according to claim 1, wherein the step of generating the metadata generates metadata that represents a relationship between the action event and the change event.

4. The method according to claim 1, wherein

the action performed by the user on the content is placing a pointer on the content, and

the change in the content is that new content is displayed in addition to the content.

5. The method according to claim 2, wherein

the content is an element of a hierarchical menu, and

the new content is a submenu included in the element.

6. The method according to claim 1, wherein the step of generating the metadata generates the metadata based on a sequence of the action event and the change event.

7. The method according to claim 6, wherein the step of generating the metadata generates the metadata based on a sequence that has occurred more or most frequently among a plurality of sequences.

8. The method according to claim 1, wherein the step of generating the metadata generates metadata that indicates a type of the content.

9. The method according to claim 1, wherein

the action performed by the user on the content is clicking on the content,

the change in the content is a change in an attribute of the content, and

the step of generating the metadata generates metadata which indicates that the content is a checkbox provided that the clicking and the change in the attribute have been repeated multiple times.

10. The method according to claim 1, wherein information identifying the content as a target is included in the metadata.

11. The method according to claim 10, wherein the information identifying the content includes a wildcard URL or a wildcard Xpath.

12. The method according to claim 1, wherein a separate computer is connected to the network, and the method further comprises the steps of:

transmitting the metadata to the computer; and

receiving the metadata from the computer in response to the client requesting the server to transmit the content.

13. The method according to claim 1, wherein the metadata improves accessibility to the content for a screen reader.

14. The method according to claim 1, wherein the metadata improves accessibility to the content for a web spider.

15. The method according to claim 1, wherein the client comprises a display device, a pointing device, and a communication device, and the method further comprises the step of:

displaying content transmitted from the server via the network on the display device through the communication device; and

operating on the content displayed on the display device in response to the user manipulating the pointing device.

16. A method for application to a client connected with a server via a network, the method comprising the steps of:

tracking an action event indicative of an action performed by a user on content displayed on the client and a change event indicative of a change in the content; and

generating metadata for improving accessibility to the content based on the action event and the change event.

17. An article of manufacture tangibly embodying computer readable non-transitory instructions which, when implemented, cause a server connected with a client via a network, to carry out the steps of a method comprising:

receiving from the client an action event indicative of an action performed by a user on content displayed on the client and a change event indicative of a change in the content; and

generating metadata for improving accessibility to the content based on the action event and the change event.
