Abstract

A method for visualizing time-varying data from one or more data streams at a different interval than the interval between acquisition of the individual data items in the data stream. Data received is combined, or aggregated, between updates of a display to retain some information from each element. The aggregated data is then displayed at the next update of the display in a number of display elements. The characteristics of the display elements, and the organization of the elements represent changes in the data streams.

Claims

1. A system for displaying the characteristics of time-varying data from one or more data streams comprised of a series of data items on a display which is updated at successive display update intervals characterized by:

means for producing a display control signal by aggregating a plurality of items of data from one or more of the time-varying data streams and producing the display control signal at the expiration of the display update interval; and

means for producing one or more display elements on the display in response to the display control signal, the characteristics of the display element representing the characteristics of the time-varying data;

one or more of the data streams being discrete data; and

said aggregation comprising selecting the data item occurring most or least often from one or more of the data streams.

2. The system of claim 1 wherein the data items aggregated fall with the display update interval.

3. The system of claim 1 wherein the data items aggregated come from a larger interval of time then the display update interval.

4. The system of claim 1 wherein the interval over which the data items are aggregated is controlled by the user.

5. The system of claim 1 wherein the means for producing a display control signal is capable of aggregating data items from both periodic and aperiodic data streams.

6. The system of claim 1 wherein:

the data stream comprises stored data items occurring at known periodic or aperiodic intervals;

the time interval on which data items are aggregated is selected by the user in proportion to the display update interval to cause the aggregated data to be viewed at a proportionally faster rate than the data items in the data streams originally occurred; and

the time interval over which data items are aggregated may be changed while simultaneously viewing data.

7. The system of claim 1 wherein the user may select among a plurality of aggregation techniques while simultaneously viewing data.

8. The system of claim 7 wherein in the user may select different aggregation techniques for different data streams or groups of data streams while simultaneously viewing data.

9. The system of claim 1 wherein the display update interval is determined by the limitations of the user'"'"'s perception.

10. The system of claim 1 wherein the display update interval is determined by the capabilities of the display.

11. The system of claim 1 wherein:

the data streams comprise data passing through a communication link, and;

the display update interval is determined by the limitations of the communication link.

12. The system of claim 1 wherein the display update interval is determined by either the limitations of the user'"'"'s perception, the display, or the slowest communication link through which one or more of the data streams must pass.

13. The system of claim 1 wherein the display update interval is determined as a user preference.

14. The system of claim 13 wherein the display update interval may be selected by the user while simultaneously viewing data.

15. The system of claim 1 wherein the arrangement of the display elements on the display represents some relationship between the data streams.

16. The system of claim 1 wherein one or more of the data streams are digitized analog data or continuous-value digital data, and aggregation comprises an average of data from one or more of the data streams.

17. The system of claim 1 wherein one or more of the data streams are digitized analog data or continuous-value digital data, and aggregation comprises using a critical value of the data from one or more of the data streams, if that critical data value is reached or exceeded during the period of data aggregation, as part of the display control signal.

18. The system of claim 1 wherein one or more of the data streams are discrete data, and aggregation comprises one or more combinations, each of the combinations comprising at least two states within one or more of the data streams.

19. The system of claim 1 wherein one or more of the data streams are discrete data, each data value is assigned a different color, and the aggregation comprises a quantitative color blending of data item colors from one or more of the data streams.

20. A system for displaying the characteristics of time-varying data from one or more data streams comprised of a series of data items on a display which is updated at successive display update intervals characterized by:

means for producing a display control signal by aggregating a plurality of items of data from one or more of the time-varying data streams and producing the display control signal at the expiration of the display update interval; and

means for producing one or more display elements on the display in response to the display control signal, the characteristics of the display element representing the characteristics of the time- varying data;

said data streams comprising stored data including an indication of the time interval between successive data items in the data streams; and

the display update interval being shorter than the time interval between successive data items.

21. A method of displaying the characteristics of time-varying data from one or more data streams comprised of a series of data items on a display comprising:

selecting an display update interval for determining when the characteristics of data from one or more of the data streams will be displayed on the display;

aggregating a plurality of data items from on or more data streams; and

displaying the aggregated data as one or more display elements at the end of the display update interval, each of the one or more display elements representing characteristics of data from one or more of the data streams, the visual characteristics of each of the display elements representing changes in the characteristics of one or more of the data streams, wherein

said data items are discrete data, and

said aggregation comprises selecting the data items occurring most or least often from one or more of the data streams.

22. The method of claim 21 wherein the data items aggregated come from a larger interval of time then the display update interval.

23. The method of claim 21 wherein the selection of the data items to be aggregated is controlled by the user.

24. The method of claim 21 wherein:

the data stream comprises stored data items occurring at known periodic or aperiodic intervals;

the time interval on which data items are aggregated is selected by the user in proportion to the display update interval to cause the aggregated data to be viewed at a proportionally faster rate than the data items in the data streams originally occurred;

and the time interval over which data items are aggregated may be changed while simultaneously using data.

25. The method of claim 21 wherein the user may select among a plurality of aggregation techniques while simultaneously viewing data.

26. The method of claim 25 wherein in the user may select different aggregation techniques for different data streams or groups of data streams while simultaneously viewing data.

27. The method of claim 21 where in the update rate is selected based on the capabilities of the display.

28. The method of claim 21 wherein the minimum length of time between one update of the display and the next update of the display is determined by the persistence of vision of the user.

29. The method of claim 21 wherein the minimum length of time between one update of the display and the next update of the display is determined by the maximum rate at which data can be transferred to the display.

30. The method of claim 21 wherein the minimum length of time between one update of the display and the next update of the display is chosen by as a preference by the user.

31. The method of claim 21 wherein the pre-defined update rate is determined by the slowest of either persistence of vision of the user, the capabilities of the display, or the slowest communication link through which the data must pass.
