Abstract

Representing display objects, such as windows, in a graphical user interface in such a way as to indicate which display object should be focused on by a user as a currently active display object. The method includes modifying appearance characteristics of a first display object, the first display object transitioning from an active to an inactive state, to make the first display object appear farther from a user than at least one other display object. The method further includes modifying appearance characteristics of a second display object, the second display object transitioning from the inactive state to the active state, to make the second display object appear closer to the user than at least the first display object. The user intuitively recognizes the nearer display object as the currently active display object.

Claims

1. A method of representing display objects comprising:

modifying appearance characteristics of a first display object, the appearance characteristics comprising at least one of brightness, contrast, and clarity, the first display object transitioning from an active to an inactive state, to make the first display object appear farther from a user than at least one other display object, by

defining a region of an image portrayed by the first display object,

determining an average value of pixels of the region;

replacing values of pixels of the region in the first display object with the average value; and

repeating the defining, determining, and replacing actions for all regions of the first display object; and

modifying appearance characteristics of a second display object, the second display object transitioning from the inactive state to the active state, to make the second display object appear closer to the user than at least the first display object.

2. The method of claim 1, wherein modifying appearance characteristics of the first display object comprise decreasing at least one of brightness, contrast, and clarity of the first display object.

3. The method of claim 1, wherein modifying appearance characteristics of the first display object comprise decreasing brightness, contrast, and clarity of the first display object.

4. The method of claim 1, wherein modifying appearance characteristics of the first display object comprise increasing brightness and decreasing contrast and clarity of the first display object.

5. The method of claim 1, wherein modifying appearance characteristics of the second display object comprise increasing at least one of brightness, contrast, and clarity of the second display object.

6. The method of claim 1, wherein the first and second display objects comprise windows in a windowing environment.

7. The method of claim 6, wherein the first display object comprises a parent window, and the second display object comprises a child window.

8. The method of claim 1, further comprising repeating the modifying of appearance characteristics of the first display object over a first period of time.

9. The method of claim 1, further comprising repeating the modifying of appearance characteristics of the second display object over a second period of time.

10. The method of claim 1, further comprising repeating the modifying of appearance characteristics of the first display object over a first period of time, and repeating the modifying of appearance characteristics of the second display object over a second period of time, wherein the first period of time equals the second period of time.

11. An article comprising:

a machine readable medium having a plurality of machine readable instructions, wherein when the instructions are executed by a processor, the instructions cause modification of appearance characteristics of a first display object, the appearance characteristics comprising at least one of brightness, contrast, and clarity, the first display object transitioning from an active to an inactive state, thereby making the first display object appear farther from a user than at least one other display object, by defining a region of an image portrayed by the first display object, determining an average value of pixels of the region, replacing values of pixels of the region in the first display object with the average value, and repeating the defining, determining, and replacing actions for all regions of the first display object; and

modification of appearance characteristics of a second display object, the second display object transitioning from the inactive state to the active state, thereby making the second display object appear closer to the user than at least the first display object.

12. The article of claim 11, wherein instructions to modify appearance characteristics of the first display object comprise instructions to decrease at least one of brightness, contrast, and clarity of the first display object.

13. The article of claim 11, wherein instructions to modify appearance characteristics of the first display object comprise instructions to decrease brightness, contrast, and clarity of the first display object.

14. The article of claim 11, wherein instructions to modify appearance characteristics of the first display object comprise instructions to increasing brightness and decreasing contrast and clarity of the first display object.

15. The article of claim 11, wherein instructions to modify appearance characteristics of the second display object comprise instructions to increase at least one of brightness, contrast, and clarity of the second display object.

16. The article of claim 11, wherein the first and second display objects comprise windows in a windowing environment.

17. The article of claim 16, wherein the first display object comprises a parent window, and the second display object comprises a child window.

18. The article of claim 11, further comprising instructions to repeat the modification of appearance characteristics of the first display object over a first period of time.

19. The article of claim 11, further comprising instructions to repeat the modification of appearance characteristics of the second display object over a second period of time.

20. The article of claim 11, further comprising instructions to repeat the modification of appearance characteristics of the first display object over a first period of time, and to repeat the modification of appearance characteristics of the second display object over a second period of time, wherein the first period of time equals the second period of time.
