Abstract

A simplified graphical user interface display unit which enables the user to view and change cache size relative to received cached documents and also to enable the user to track a sequence of received documents or a sequence of other computer controlled events. A data processor controlled receiving display station for receiving Web documents has apparatus for storing a sequence of received Web documents, tracking the sequence cf stored Web documents in combination with a displayed graphical unit including: a sequence of nondescriptive markers corresponding to the sequence of stored Web documents and a user interactive implementation for stepping sequentially through the sequence of markers. The receiving display station has caching apparatus of variable size and the graphical unit further includes an interactive implementation for varying the cache size which includes a space for the sequence of markers proportional in size to the size of the cache, and the implementation to vary the cache size varies the size of the space for the sequence of markers.

Claims

1. A data processor controlled display system with a graphical user interface comprising:

means for tracking a sequence of data processor controlled events, and

a displayed graphical unit including;

a sequence of non-descriptive markers corresponding to said sequence of events, and

user interactive means for stepping sequentially through said sequence of markers.

2. The data processor controlled display system of claim 1 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying a description of the event represented by the marker.

3. The data processor controlled display system of claim 1 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying the event corresponding to the selected marker.

4. The data processor controlled display system of claim 3 wherein said selecting means include pointing means.

5. The data processor controlled display system of claim 3 wherein said selecting means include said means for stepping.

6. A World Wide Web (Web) communication network comprising:

a data processor controlled receiving display station for receiving Web documents including;

means for storing a sequence of received Web documents,

means for tracking said sequence of stored Web documents, and

a displayed graphical unit including;

a sequence of non-descriptive markers corresponding to said sequence of stored Web documents, and

user interactive means for stepping sequentially through said sequence of markers.

7. The Web communication network of claim 6 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying the Web document corresponding to the selected marker.

8. The Web communication network of claim 7 wherein said selecting means include pointing means.

9. The Web communication network of claim 7 wherein said selecting means include said means for stepping.

10. The Web communication network of claim 6 wherein said storing means comprise cache means of variable size, and

said graphical unit further includes interactive means for varying said cache size.

11. The Web communication network of claim 10 wherein said graphical unit further comprises a space for said sequence of markers proportional in size to the size of said cache means, and

said means for varying said cache size vary the size of said space for said sequence of markers.

12. In a data processor display system, a method for controlling a sequence of data processor controlled events on a graphical user interface comprising:

tracking a sequence of data processor controlled events, and

displaying a graphical unit including;

displaying a sequence of nondescriptive markers corresponding to said sequence of events, and

enabling a user to interactively step sequentially through said sequence of markers.

13. The method of claim 12 further including the steps of:

selecting one of said markers, and

displaying a description of the event represented by the marker responsive to said selecting step.

14. The method of claim 12 further including steps of:

selecting one of said markers, and

displaying the event corresponding to the selected marker responsive to said selecting step.

15. The method of claim 14 wherein said selecting step is done by pointing means.

16. The method of claim 14 wherein said selecting is done through said stepping through said markers.

17. In a Web communication network, a method for controlling a sequence of received Web documents at a data processor controlled receiving display station comprising:

storing a sequence of received Web documents,

tracking said sequence of stored Web documents, and

displaying a graphical unit including;

displaying a sequence of nondescriptive markers corresponding to said sequence of stored Web documents, and

enabling a user to interactively step sequentially through said sequence of markers.

18. The method of claim 17 further including:

selecting one of said markers, and

displaying the Web document corresponding to the selected marker responsive to said selecting step.

19. The method of claim 18 wherein said selecting step is done by pointing means.

20. The method of claim 19 wherein said selecting step is done by stepping through said markers.

21. The method of claim 17 wherein

said storing step includes caching said Web documents in a variable size cache, and

further including the step of enabling the user to interactively vary said cache size.

22. The method of claim 21 wherein the user is enabled to vary the cache size through steps including:

providing a space for said sequence of markers in said graphical unit proportional in size to the size of said cache, and

enabling the user to varying said cache size by varying the size of said space for said sequence of markers.

23. A computer program having code recorded on a computer readable medium for controlling a sequence of data processor controlled events through the graphical user interface of a data processor controlled display system comprising:

means for tracking a sequence of data processor controlled events, and

a displayed graphical unit including;

a sequence of nondescriptive markers corresponding to said sequence of events, and

user interactive means for stepping sequentially through said sequence of markers.

24. The computer program of claim 23 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying a description of the event represented by the marker.

25. The computer program of claim 23 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying the event corresponding to the selected marker.

26. The computer program of claim 25 wherein said selecting means include pointing means.

27. The computer program of claim 25 wherein said selecting means include said means for stepping.

28. A computer program having code recorded on a computer readable medium for controlling a sequence of received Web documents at a data processor controlled receiving display station in a Web communication network comprising:

means for storing a sequence of received Web documents,

means for tracking said sequence of stored Web documents, and

a displayed graphical unit including;

a sequence of nondescriptive markers corresponding to said sequence of stored Web documents, and

user interactive means for stepping sequentially through said sequence of markers.

29. The computer program of claim 28 further including:

means for selecting one of said markers, and

means responsive to said selecting means for displaying the Web document corresponding to the selected marker.

30. The computer program of claim 29 wherein said selecting means include pointing means.

31. The computer program of claim 29 wherein said selecting means include said means for stepping.

32. The computer program of claim 28 wherein
