Abstract

A visually aging scroll bar is associated with a window or viewport on a computer display as part of a computer system, and contains a slider to indicate relative positioning in the window of a document, such as a data file, image file, audio file, text file, or spreadsheet. The current position of the scroll bar slider is monitored by the computer system. After a first predetermined sampling period has elapsed, a first region matching the current position of the scroll bar slider is created. The visual appearance of the region is determined by a predetermined region heating rate. For example, a newly created region starts at "cold", which can be indicated by a violet-indigo color. After a second sampling period has elapsed, the computer system again checks the current position of the scroll bar slider. If the current position still matches the first region, the visual appearance of the first region symbolically "warms up" as indicated by the region heating rate. This incrementally changing visual appearance (for example, from violet to indigo, blue, green, yellow, orange and finally a deep red) continues for as long as the current slider position matches the first region, up until a maximum region symbolic "temperature" is reached.

Claims

1. A computer system having a display and a scroll bar having a slider, said slider representing a position within a document, said computer system comprising:

means for detecting a first position, wherein said first position is the current position of said slider;

means for creating a first region in said scroll bar, said first region having an upper boundary and a lower boundary and including said first position; and

means for incrementally changing the visual appearance of said first region in said scroll bar as long as said current position remains said first position.

2. The computer system of claim 1, further comprising:

means for incrementally changing the visual appearance of said first region in said scroll bar when said current position is no longer said first position.

3. The computer system of claim 2 further comprising:

means for enabling said means for incrementally changing the visual appearance of said first region in said scroll bar when said current position is no longer said first position provided said current position is within said slider.

4. The computer system of claim 1, further comprising:

means for determining that said first region has reached a predetermined maximum symbolic temperature; and

means responsive to said determining means which disable said means for incrementally changing the visual appearance of said first region as long as said current position remains said first position.

5. The computer system of claim 2, further comprising:

means for changing the visual appearance of said first region to be the same as the visual appearance of said scroll bar when said first region reaches a predetermined minimum temperature.

6. The computer system of claim 1, wherein the visual appearance of said first region is a color associated with a specific symbolic temperature that incrementally changes at a predetermined symbolic region heating rate at a predetermined sampling rate.

7. The computer system of claim 6, wherein symbolically warmer temperatures of said region indicate high usage and are represented by colors in the low end of the light spectrum.

8. The computer system of claim 6, further comprising:

means for allowing a user to select indicators of symbolically warmer and cooler temperatures.

9. The computer system of claim 2, wherein the visual appearance of said first region is a color associated with a specific symbolic temperature that incrementally decreases at a predetermined symbolic region cooling rate at a predetermined sampling rate.

10. The computer system of claim 9, wherein symbolically cooler temperatures of said region indicate low usage and are represented by colors in the high end of the light spectrum.

11. The computer system of claim 1, further comprising:

means for temporarily suspending said means for incrementally changing the visual appearance of said first region in response to a suspend sampling request; and

means for resuming said means for incrementally changing the visual appearance of said first region in response to a resume sampling request.

12. The computer system of claim 2, further comprising:

means for temporarily suspending said means for incrementally changing the visual appearance of said first region in response to a suspend sampling request; and

means for resuming said means for incrementally changing the visual appearance of said first region in response to a resume sampling request.

13. The computer system of claim 1, further comprising:

means for detecting that said slider has moved to a second position;

means for concluding that said second position is not said first position;

means for creating a second region in said scroll bar, said second region including said second position;

means for incrementally changing the visual appearance of said second region as long as said second position remains the current position, wherein the visual appearance of said second region is a second color associated with a second specific symbolic temperature that incrementally changes at a predetermined symbolic region heating rate at a predetermined sampling rate; and

means for incrementally changing the visual appearance of said first region when said first position is no longer the current position, wherein the visual appearance of said first region is a first color associated with a first specific symbolic temperature that incrementally changes at a predetermined symbolic region cooling rate at said predetermined sampling rate.

14. The computer system of claim 13, wherein said first region and said second region have an overlapping portion.

15. The computer system of claim 14, wherein the visual appearance of said overlapping portion is a third color associated with a third temperature, said third temperature being the sum of said first temperature and said second temperature.

16. The computer system of claim 1, further comprising:

means for saving said first region upon receipt of an indication that work on said document is completed;

means for restoring said first region upon receipt of an indication that work on said document is to resume.

17. The computer system of claim 1, further comprising:

means for executing said means for incrementally changing the visual appearance of said first region only if said document exceeds a predetermined minimum size.

18. The computer system of claim 2, further comprising:

means for executing said means for incrementally changing the visual appearance of said first region only if said document exceeds a predetermined minimum size.

19. A program product having a scroll bar and a slider, said scroll bar having a slider, said slider representing a position within a document, said program product comprising:

means for detecting a first position, wherein said first position is the current position of said slider;

means for creating a first region in said scroll bar, said first region having an upper boundary and a lower boundary and including said first position; and

means for incrementally changing the visual appearance of said first region in said scroll bar as long as said current position remains said first position.

20. A method for creating a visually aging scroll bar, said scroll bar having a slider, said slider representing a position within a document, said method comprising the machine-executed steps of:

detecting a first position, wherein said first position is the current position of said slider;

creating a first region in said scroll bar, said first region having an upper boundary and a lower boundary and including said first position; and

incrementally changing the visual appearance of said first region in said scroll bar as long as said current position remains said first position.
