Abstract

A Universal Client with a self-contained scripting language called GUIScript forms a computer architecture independent device for generating and displaying a graphic user interface (GUI). Preferably, the computer executing the Universal Client includes circuitry for presenting a plurality of GUI objects to thereby form a GUI, for generating scripts defining respective ones of the GUI objects, for generating a GUISCRIPT defining the GUI, for storing one of the scripts and the GUISCRIPT, for reading one of the scripts and the GUI script; and for scripting behavior of a program responsive to operator interaction with one of the GUI objects.

Claims

1. A computer architecture independent device for generating and displaying a graphic user interface (GUI), comprising:

means for generating scripts defining GUI objects;

means for generating a GUIScript defining said GUI;

means for presenting a plurality of said GUI objects responsive to said GUIScript to thereby form said GUI;

means for storing one of said scripts and said GUIScript;

means for reading one of said scripts and said GUIScript; and

means for scripting behavior of a program responsive to operator interaction with one of said GUI objects.

2. A computer comprising:

a storage device which stores a document written in hypertext markup language (HTML), said HTML document including an applet tag for invoking a Universal Client device and computer readable instructions for generating said Universal Client device and which stores computer readable instructions for permitting said computer to utilize a World Wide Web browser providing a JAVA™

virtual machine; and

a processor for initializing and executing said Universal Client device on said computer using said JAVA™

virtual machine to thereby generate predetermined graphical user interface (GUI) objects responsive to a GUIScript and display said GUI objects on said computer.

3. The computer as recited in claim 2, wherein said predetermined GUI objects are defined by a script stored on said storage device, and wherein said Universal Client device generates said predetermined GUI objects responsive to said script.

4. The computer as recited in claim 2, wherein said storage device stores predetermined GUI objects, and wherein said Universal Client device interacts with said predetermined GUI objects responsive to a script.

5. The computer as recited in claim 2, wherein one of said predetermined GUI objects comprises a MultiMedia presentation.

6. The computer as recited in claim 2, wherein said storage device stores predetermined GUI objects and predetermined JAVA™

objects.

7. The computer as recited in claim 6, wherein one of said predetermined JAVA™

objects comprises a timer for determining time separation between display of a selected one of said predetermined GUI object and operator response thereto.

8. The computer as recited in claim 2, wherein said GUIScript includes a plurality of scripted instructions and wherein said Universal Client device executes a second one of said scripted instructions before execution of a first one of said scripted instructions has been completed.

9. The computer as recited in claim 2, wherein said storage device stores predetermined GUI objects, and wherein said Universal Client device interacts with said predetermined GUI objects responsive to a training script to thereby display a training sequence comprising said predetermined GUI objects.

10. The computer as recited in claim 9, wherein one of said predetermined GUI objects comprises a MultiMedia presentation.

11. A computer comprising:

means for storing a document written in hypertext markup language (HTML), said HTML document including an applet tag for invoking a Universal Client device and computer readable instructions for generating said Universal Client device and for storing computer readable instructions for permitting said computer to utilize a virtual machine; and

processing means for initializing and executing said Universal Client device on said computer using said virtual machine to thereby generate predetermined graphical user interface (GUI) objects responsive to a GUIScript and display said GUI objects on said computer.

12. The computer as recited in claim 11, wherein said virtual machine comprises a JAVA™

virtual machine.

13. The computer as recited in claim 11, wherein said predetermined GUI objects are defined by a script stored on said storing means, and wherein said Universal Client device generates said predetermined GUI objects responsive to said script.

14. The computer as recited in claim 11, wherein said storing means comprises object storing means for storing predetermined GUI objects, and wherein said Universal Client device interacts with said predetermined GUI objects responsive to a script.

15. The computer as recited in claim 11, wherein one of said predetermined GUI objects comprises a MultiMedia presentation.

16. The computer as recited in claim 11, wherein said storing means comprises object storing means for storing predetermined GUI objects and predetermined JAVA™

objects.

17. The computer as recited in claim 16, wherein one of said predetermined JAVA™

objects comprises a timer for determining response time between display of a selected one of said predetermined GUI objects and operator response thereto.

18. The computer as recited in claim 11, wherein said GUIScript includes a plurality of scripted instructions and wherein said Universal Client device executes a second one of said scripted instructions before execution of a first one of said scripted instructions has been completed.

19. The computer as recited in claim 11, wherein said storing means comprises object storing means for storing predetermined GUI objects, and wherein said Universal Client device interacts with said predetermined GUI objects responsive to a training script to thereby display a training sequence comprising said predetermined GUI objects.

20. The computer as recited in claim 19, wherein one of said predetermined GUI objects comprises a MultiMedia presentation.
