Abstract

A user interface for screen phones monitors telephone line state information and displays user interface controls and telephone line status information dependent on the telephone line state. The user interface includes a display element referred to as a call slip that expands and collapses in response to changes in telephone line state and user input. The call slip updates the information that it displays based on telephone line state changes and information communicated from one or more telephony monitoring applications. The call slip displays user interface controls representing tasks that are dependent on information derived from a telephone call, such as caller ID information. The software used to control the display of call slips and to monitor telephone line state is part of a software platform that may be customized for a particular device or application. For example, an implementer may select default display elements and monitoring application programs from the platform and add custom display elements that communicate with the default programs via their programming interfaces.

Claims

1. A computer readable medium comprising computer-executable instructions stored thereon, wherein execution of the instructions performs the following steps:

generating a set of executable user interface control programming objects operable to present user interface controls in a screen phone user interface, wherein the user interface control programming objects expose an application programming interface comprising at least one method for processing events directed from an executable user interface element programming object;

presenting via the executable user interface element programming object an element of the screen phone user interface;

exposing an application programming interface comprising at least one method for receiving event notifications and

forwarding received notifications to the user interface control programming objects.

2. The computer readable medium of claim 1 wherein the application programming interface of the user interface control programming objects and the programming interface of the user interface element programming object both comprise a method for receiving and processing events.

3. The computer readable medium of claim 1 wherein the programming interface of the user interface element programming object comprises a method for making the user interface element invisible in response to a full screen event.

4. The computer readable medium of claim 1 further comprising executable instructions for performing the following:

generating a contained user interface element programming object having an application programming interface comprising a method for receiving event notifications, wherein the contained user interface element programming object is operable to present a contained element displayed within a user interface element and to forward directives received from the display programming object to user interface control programming objects designated as belonging to the contained element.

5. The computer readable medium of claim 3 wherein the contained element is activated by adding information listing a class of the contained user interface element programming object in a configuration store.

6. The computer readable medium of claim 5 wherein the contained element is activated remotely.

7. The computer readable medium of claim 1 wherein the user interface element programming object comprises a programming interface for receiving telephone line state events from a program monitoring for state changes in the telephone line.

8. The computer readable medium of claim 7 wherein the user interface element programming object is operable to selectively display an indicator of the telephone line state in response to a telephone line state event.

9. The computer readable medium of claim 7 wherein the user interface element programming object is operable to display an indicator of caller ID information in response to a telephone line state event conveying the caller ID information to the user interface element programming object.

10. The computer readable medium of claim 1 wherein the user interface element programming object logically contains one or more control objects, each control object having a programming interface, and each control object operable to present a user interface control in a portion of the display and responsive to user input to the user interface control.

11. The computer readable medium of claim 10 wherein the control object is operable to display a user interface control depending on telephone line state.

12. The computer readable medium of claim 1 containing further executable instructions for generating a monitoring application, wherein the monitoring application is operable to call a method in a programming interface of the user interface element programming object to inform the user interface element programming object of telephone line state changes.

13. A method of customizing a software system for a screen phone, wherein the software system comprises one or more monitoring applications monitoring telephone line state information, one or more default element objects presenting default elements in a user interface, and a display manager controlling the user interface and facilitating communication within the software system, the method comprising:

adding to the software system a custom element object that controls the display of a corresponding custom user interface element in the user interface;

wherein the custom element object exposes a programming interface comprising one or more methods that mirror one or more methods of a programming interface of the display manager and one or more methods of a programming interface of the default element objects, and wherein the custom element object is operable to receive telephone line state information and forward the information to one or more objects associated with the custom element via at least one of the mirrored methods.

14. The method of claim 13 including:

creating a custom user interface control to include in one of the default elements, the custom user interface control having a programming interface for receiving telephone state information.

15. The method of claim 13 including:

creating a custom user interface control to include in the custom element, the custom user interface control having a programming interface for receiving telephone state information.

16. The method of claim 13 including:

creating a custom monitoring application program; and

creating a custom user interface control to include in the custom element, the custom user interface control having a programming interface for receiving telephone state information from the custom telephony monitoring application program.

17. An extensible telephone software system providing telephony functionality and a displayed user interface, the software system comprising:

a plurality of telephony monitoring applications for sensing changes in telephone line state and sending notifications indicating telephone line state;

a set of one or more container objects operable to receive notifications indicating telephone line state from the telephony monitoring applications, the container objects further operable to present a user interface manifestation and forward the received notifications; and

a set of one or more containee objects operable to display a user interface control within the user interface manifestation and further operable to receive notifications originating from one or more of the plurality of telephony monitoring applications and forwarded by the container objects;

wherein additional functionality can be added to the software system by adding additional containee objects.

18. The system of claim 17 wherein the container object and the containee objects have application programming interfaces comprising a method for receiving telephony events.

19. The system of claim 18 wherein the application programming interfaces comprise at least one method for receiving directives originating from one or more of the telephony monitoring applications.

20. The system of claim 17 wherein the container object and the containee objects have application programming interfaces comprising a method for indicating a change in telephone line state.
