Abstract

An embodiment of the invention includes an information appliance system (100) having an information appliance device (102) with a focus manager (206). Among other things, the focus manager is disposed to manage a plurality of asynchronous entities (214). Focus manager (206) receives an asynchronous request (209), stores it in a queue (250) and assigns it a priority level (252, 254, 256). Based on the priority level (252, 254, 256), an asynchronous entity (214) takes over control of user interface device resources from an entity (210), utilizes the resources, and returns them to the entity (210).

Claims

1. An information system that manages asynchronous requests for user interface resources, the system comprising:

an information device having a user interface that includes a plurality of resources;

a non-user-selectable application operable to utilize the plurality of user interface device resources;

an application manager operable to input information from the applications, wherein the manager comprises a queue; and

an asynchronous request from the asynchronous application is operable to request any of plurality of the user interface device resources, wherein the asynchronous request is received by the application manager, wherein the asynchronous request is stored in the queue and assigned a priority level, wherein based on the priority level the asynchronous application;

interrupts access to the user interface resources by a lower-priority application, takes control of the plurality of user interface device resources from the lower priority application, utilizes the plurality of user interface device resources, and relinquishes control of the plurality of user interface device resources.

2. The information system of claim 1, wherein the priority level is comprised of an importance factor and an urgency factor, wherein the importance factor is stored on the information system, and wherein the urgency factor is supplied by the asynchronous application.

3. The information system of claim 2, further comprising a plurality of asynchronous application attributes, wherein the plurality of asynchronous application attributes are stored in the information system, and wherein the plurality of asynchronous application attributes comprise the importance factor.

4. The information system of claim 2, wherein the importance factor and the urgency factor are combined to create the priority level.

5. The information system of claim 1, wherein the asynchronous application relinquishes control of the plurality of user interface device resources upon acknowledgment of the asynchronous application.

6. The information system of claim 1, wherein the asynchronous entity takes control of the plurality of user interface device resources immediately.

7. The information system of claim 1, wherein the asynchronous request is received by the application manager at a receipt time, wherein the asynchronous application takes control of the plurality of user interface device resources at an implementation time, wherein the implementation time is after the receipt time, and wherein a difference between the implementation time and the receipt time is controlled by the priority level.

8. The information system of claim 1, wherein the asynchronous application takes control of a first set of the plurality of user interface device resources, and wherein the asynchronous application utilizes the first set of the plurality of user interface device resources.

9. The information system of claim 1, wherein the asynchronous application relinquishes control of the user interface resources to one of the group of the application that was interrupted and another application in the queue.

10. The information system of claim 1, wherein the asynchronous application includes a service.

11. The information system of claim 1, wherein the asynchronous application includes a subsystem.

12. A method of managing asynchronous requests for user interface resources in an information system, the method comprising the steps of:

providing an information device having a user interface that includes a plurality of resources;

providing a non-user-selectable application operable to utilize the plurality of user interface device resources;

providing an application manager operable to input information from the applications, wherein the manager comprises a queue;

providing an asynchronous request from the asynchronous application is operable to request any of plurality of the user interface device resources, wherein the asynchronous request is received by the application manager;

assigning a priority level to the asynchronous request;

storing the asynchronous request in the queue;

wherein based on the priority level;

having asynchronous entity;

interrupt access to the user interface resources by a lower-priority application;

take control of the plurality of user interface device resources from the lower priority application;

utilizing the plurality of user interface device resources; and

relinquishing control of the plurality of user interface device resources.

13. The method of claim 12, wherein assigning a priority level comprises assigning an importance factor and an urgency factor, wherein the importance factor is stored on the information system, and wherein the urgency factor is supplied by the asynchronous request.

14. The method of claim 13, further comprising providing a plurality of asynchronous application attributes, wherein the plurality of asynchronous application attributes are stored in the information system, and wherein the plurality of asynchronous application attributes comprise the importance factor.

15. The method of claim 13, further comprising combining the importance factor and the urgency factor to create the priority level.

16. The method of claim 12, wherein relinquishing control of the plurality of user interface device resources comprises relinquishing control of the plurality of user interface device resources upon acknowledgment of the asynchronous entity.

17. The method of claim 12, wherein taking control of the plurality of user interface device resources comprises taking control of the plurality of user interface device resources immediately.

18. The method of claim 12, further comprising providing a receipt time, wherein the asynchronous request is received by the application manager at the receipt time, providing an implementation time, wherein the asynchronous application takes control of the plurality of user interface device resources at the implementation time, wherein the implementation time is after the receipt time, and wherein a difference between the implementation time and the receipt time is controlled by the priority level.

19. The method of claim 12, further comprising taking control of a first set of the plurality of user interface device portions, and wherein the asynchronous application utilizes the first set of the plurality of user interface device portions.

20. The method of claim 12, wherein the relinquishing step comprises relinquishing control of the plurality of user interface device resources to one of the group of the application that was interrupted and another application in the queue.
