Abstract

An operating method for a computer architecture independent device generating and displaying a graphic user interface (GUI) on a client computer operatively connected to a server computer includes steps for scripting both behavior of a program responsive to operator interaction with one of the GUI objects and client-server commands unrelated to the GUI objects, storing scripts defining respective GUI objects on the server computer, storing a GUIScript defining the GUI on the server computer, handling network protocols defining communications between the server and the client computers, sending one of the scripts and the GUIScript from the server computer to the client computer, receiving one of the scripts and the GUI script on the client computer, and presenting a plurality of GUI objects to thereby form a GUI on the client computer.

(b) transmitting said HTML document and said first instructions for generating said Universal Client device from the first computer to the second computer;

(c) storing computer readable instructions for generating a World Wide Web browser providing a JAVA™

virtual machine on a second storage device disposed within the second computer; and

(d) executing said Universal Client device on the second computer using said JAVA™

virtual machine to thereby generate predetermined graphical user interface (GUI) objects displaying GUI objects on the second computer responsive to a GUIScript.

3. The operating method for the computer system as recited in claim 2, wherein:

said step (a) further comprises;

storing said HTML document including said applet tag for invoking said Universal Client device, said first instructions for generating said Universal Client device, and a script defining said predetermined GUI objects on said first storage device disposed within the first computer; and

said Universal Client device generates said predetermined GUI objects responsive to said script.

4. The operating method for the computer system as recited in claim 2, further comprising a step for:

(e) storing a script defining said predetermined GUI objects on said second storage device disposed within the second computer; and

wherein said Universal Client device generates said predetermined GUI objects responsive to said script.

5. The operating method for the computer system as recited in claim 2, wherein said method further comprises the step for:

(f) modifying and replacing said predetermined GUI objects responsive to an incoming GUIScript message corresponding to changing parameters associated with said first computer.

6. The operating method for the computer system as recited in claim 2, wherein said method further comprises the step for:

(g) selectively modifying and replacing said predetermined GUI objects responsive to an incoming datagram corresponding to changing parameters associated with said first computer.

7. The operating method for the computer system as recited in claim 2, wherein said method further comprises the step for:

(h) selectively modifying and replacing said predetermined GUI objects responsive to an incoming character string corresponding to changing parameters associated with said first computer.

8. The operating method for the computer system as recited in claim 2, wherein one of said predetermined GUI objects comprises a MultiMedia presentation.

9. The operating method for the computer system as recited in claim 2, wherein one of said predetermined GUI objects comprises a duration timer.

10. An operating method for a computer system generating a graphical user interface (GUI) on a first computer corresponding to a presentation generated on a second computer irrespective of the operating system differences between said first and second computers, wherein the first computer includes a character string generator and the second computer includes a Universal Client device running on a virtual machine, said method comprising the steps for:

generating a string corresponding to a desired GUI;

generating said GUI using said Universal Client device responsive to a GUIScript; and

executing said string on said Universal Client device running on said virtual machine to thereby modify said GUI.

11. The operating method for the computer system as recited in claim 10, further comprising a step for transferring said string from the first computer to the second computer.

12. The operating method for the computer system as recited in claim 11, wherein said string comprises an ASCII character string.

13. The operating method for the computer system as recited in claim 11, wherein said string comprises a datagram.

14. The operating method for the computer system as recited in claim 11, wherein said string comprises a GUIScript message.

15. An operating method for a computer system generating a graphical user interface (GUI) on a first computer screen corresponding to a presentation generated with respect to a second computer screen irrespective of the operating system differences between the respective first and second computers, said method comprising the steps for:

(a) providing a hypertext markup language (HTML) document including an applet tag corresponding to a Universal Client device;

(b) initializing and executing the Universal Client device using a JAVA™

virtual machine,

(c) parsing and interpreting a GUIScript associated with the Universal Client device to thereby cause the Universal Client device to display the GUI; and
