Abstract

The present invention is directed to a method, medium and system for use in a computing environment for managing input information. The system for facilitating input management in a computerized environment may include an input manager for processing events received from an input provider. The system may additionally include a staging area including a stack of events created by the input manager. The staging area allows access by external components. The external components may include a set of filters capable of accessing and manipulating the stack of input events and a set of monitors capable of monitoring manipulation of the stack of events.

Claims

1. A method for providing an application with event notification, the method comprising:

receiving a primary event notification, the primary event including a dictionary;

pushing a secondary event onto a stack in response to the primary event;

providing the secondary event with the dictionary from the primary event; and

sending both the secondary event and the primary event to the application.

3. The method of claim 1, further comprising registering a promoter with an input manager for the application.

4. The method of claim 1, wherein providing the secondary event comprises filtering the primary event notification.

5. The method of claim 1, further comprising adding a new device that maps to an existing interface associated with an existing device.

2. A system for exposing events for both a logical input device and a physical input device, the system comprising:

a promoter for converting logical input associated with an event to physical input; and

a dictionary accessible to an application, wherein the dictionary associates the logical input related to the event with the physical input.

6. The system of claim 2, wherein the promoter includes an internal promoter and an external promoter.

7. The system of claim 6, further comprising a promotion policy that selects the internal or external promoter to process the event.

8. The system of claim 2, further comprising application programming interfaces that map a new device to an existing interface for an existing device.

14. The medium of claim 6, further comprising defining a state of each event in a stack with the associated dictionary.

15. The medium of claim 14, wherein the first type of event involves unknown input.

16. The medium of claim 15, further comprising the second type of event with the dictionary associated with the first type of event.

9. A computer readable medium storing the computer executable instructions for performing the method of managing input to facilitate third party access, the method comprising:

processing input events received from at least two input providers by creating a staging area including a stack of input events, wherein the input events are processed by an input manager;

providing third party listener access to the staging area to enable a third party to monitor events in the staging area; and

promoting an event associated with a first registered input provider to an event associated with a second registered input provider.

10. The medium of claim 9, further comprising manipulating events in the stack using a filter.

11. The medium of claim 10, further comprising manipulating events in the stack using at least one of a mouse filter, a keyboard filter, and a stylus filter.

12. The medium of claim 10, further comprising manipulating events in the stack using a user-defined filter.

13. The medium of claim 9, further comprising associating a dictionary with each event in the stack.
