Abstract

A remote automation system is described herein that allows application accessibility information to be used remotely and extended to allow custom UI elements to be automated. The remote automation system receives a request at a remote computer for automation data related to an application running on the remote computer. The remote automation system requests automation data from the application running on the remote computer and serializes the automation data for transmission to the client computer. The system transmits the serialized automation data to the client computer in response to the request. When the client computer receives the response, the system deserializes the automation data and provides the deserialized automation data to a local application on the client computer. Thus, the remote automation system allows users to view applications running on a remote system but run accessibility applications locally.

Claims

1. A computer-implemented method for providing automation data from a remote computer to a client computer, the method comprising:

receiving at the remote computer a request over a network for automation data related to an application running on the remote computer;

requesting automation data from the application running on the remote computer;

collecting automation data received from the application;

serializing the automation data to prepare the data for transmission to the client computer; and

transmitting the serialized automation data to the client computer in response to the request.

2. The method of claim 1 wherein receiving the request comprises receiving the request through a Microsoft Terminal Services connection.

3. The method of claim 1 wherein the application implements a standard interface for retrieving automation data.

4. The method of claim 1 wherein the application provides custom UI automation data.

5. The method of claim 1 wherein the application includes executable instructions for handling custom UI item patterns.

6. The method of claim 1 wherein collecting automation data comprises gathering information about one or more properties of UI items associated with the application and organizing the data into a hierarchical format.

7. The method of claim 1 wherein serializing the automation data comprises placing the automation data into one or more packets for transmission.

8. A computer system for remoting extensible accessibility information, the system comprising:

an information gathering component configured to gather accessibility information from an application running on a remote computer;

a serializing component configured to marshal the gathered accessibility information into a format suitable for transmission over a network;

a first transport component configured to transmit the marshaled accessibility information over the network to a client computer;

a second transport component configured to receive marshaled accessibility information; and

a deserializing component configured to deserialize the accessibility information and provide the deserialized accessibility information to an application running on the client computer.

9. The system of claim 8 further comprising a UI item data store configured to store information about each user interface property, event, and pattern that is accessible through the system, wherein the UI item data store contains one or more tables of pre-defined and application-provided UI items.

10. The system of claim 8 further comprising a coordinate translation component configured to reconcile inconsistencies in the accessibility information caused by differences in the remote computer and the client computer.

11. The system of claim 10 wherein the remote and client computers display a user interface element at different locations and the coordinate translation component modifies coordinates in the accessibility information based on locations of UI items on a desktop of the client computer.

12. The system of claim 8 further comprising:

an item registration component configured to handle requests from applications to register new UI item properties; and

an identifier assignment component configured to assign identifiers to new UI properties registered by applications.

13. The system of claim 12 wherein the identifier assignment component is further configured to assign identifiers such that no two UI properties in a particular process or associated with a particular automation interface instance have the same identifier.

14. The system of claim 12 wherein the item registration component is further configured to receive information about each property, including a name and description.

15. The system of claim 8 wherein the information gathering component is further configured to interface with proxies that translate accessibility data from a common format into a format of the system.

16. A computer-readable medium encoded with instructions for controlling a computer system to deserialize automation data received from a remote computer, by a method comprising:

sending a request for automation data from a client computer to a remote computer;

receiving a response including serialized automation data for one or more remote applications;

deserializing the automation data to produce an in-memory representation of the automation data from the received response;

translating one or more coordinates in the deserialized automation data to adjust for differences in the remote computer and the client computer; and

providing the translated automation data to a local application on the client computer.

17. The computer-readable medium of claim 16 wherein the request includes information identifying an application window being displayed by the client computer of an application running on the remote computer.

18. The computer-readable medium of claim 16 wherein the automation data identifies a type and location of UI elements displayed by the remote applications.

19. The computer-readable medium of claim 16 wherein the automation data includes at least one of a property, an event, and a pattern associated with a UI item.

20. The computer-readable medium of claim 16 wherein the in-memory representation comprises one or more hierarchical data structures with logically arranged UI items.
