Abstract

A system and method for providing a graphical human-machine machine interface for a machine having controllable parts. The system utililzes client-side graphics rendering for clients in communication over a wide area network to create an interactive interface. The rendered graphical objects are interactive and represent controllable parts of the machine such that the graphical objects change appearance to reflect interaction with the machine. Optionally, the system employs server-side graphics rendering for clients in communication via a local area network.

8. The system of claim 1, wherein the at least one graphic object rendered and displayed is a representation of a part of the machine.

9. The system of claim 1, wherein the at least one graphic object rendered and displayed is capable of being displayed at the same size on displays of different resolutions.

10. The system of claim 1, wherein at the least one assigned property of at least one graphical object is stored in a style sheet.

11. The system of claim 10, wherein style sheet is selected from the group consisting of CSS, XSL, and combinations thereof.

12. The system of claim 1, wherein the computer readable code on a computer readable medium in at least one of a), b) and c) is a compiled software component.

13. The system of claim 1, wherein the computer readable code on a computer readable medium In at least one of a), b) and c) comprises functionality that is callable from and executable on a plurality of operating systems.

14. The system of claim 1, wherein the computer readable code on a computer readable medium in at least one of a), b) and c) is scriptable.

15. The system of claim 1, wherein the computer readable code on a computer readable medium in at least one of a), b) and c) comprises at least one Java Bean component.

16. The system of claim 1, further comprising:

d) computer readable code on a computer readable medium for receiving a user input associated with a displayed graphical object corresponding to the at least one controllable part of the machine;

e) computer readable code on a computer readable medium for triggering a change in at least one assigned property of the associated graphical object in response to user input;

f) computer readable code on a computer readable medium for rendering and displaying the associated graphical object following the change in at least one assigned property in response to use input; and

g) computer readable code on a computer readable medium for sending data to the machine control device, the data representing an instruction to perform an associated machine function.

17. A system for providing a plurality of graphical human-machine interfaces for a machine having a plurality of controllable parts, the system comprising:
