Abstract

A method for controlling a screen in a data processing system to generate displays that include portions of an underlying scene is disclosed. The method includes displaying on the screen a first displayed scene, detecting a long touch gesture, and displaying a second scene on the screen. The first displayed scene is characterized by a first magnification and a first offset relative to the underlying scene. The second displayed scene includes a different portion of the underlying scene and is characterized by a second magnification that is different from the first magnification. In one aspect of the invention, the second displayed scene is characterized by a second offset that is determined by the long touch gesture, and the second offset depends on the first displayed scene and the long touch gesture.

First claim

What is claimed is:

1. A method for controlling a screen in a data processing system to generate displays comprising portions of an underlying scene, said method comprising:
displaying on said screen a first displayed scene comprising a first portion of said underlying scene, said first displayed scene being characterized by a first magnification and a first offset relative to said underlying scene;
detecting a long touch gesture on said screen at a first location, said long touch gesture being characterized by a first time period, a first contact point on said screen, a second contact point on said screen, and a distance between said contact points; and
displaying a second displayed scene on said screen, said second displayed scene comprising a different portion of said underlying scene and being characterized by a second magnification that is greater than said first magnification if said distance is greater than a predetermined value and less than said first magnification if said distance is less than said predetermined value, said second displayed scene being displayed in response to said long touch gesture, said predetermined value being set prior to said long touch gesture being detected, and said second magnification being set prior to said long touch being detected.

2. The method of claim 1 wherein said second magnification changes continuously as long as said long touch gesture is maintained for a time longer than a predetermined time.

3. The method of claim 1 wherein said second displayed scene is characterized by a second offset that is determined by said touch gesture.

4. The method of claim 3 wherein said second offset depends on said first displayed scene and said touch gesture.

5. The method of claim 1 further comprising displaying a third displayed scene on said screen after a second time period if said touch gesture is maintained for that second time period, said third displayed scene comprising a different portion of said underlying scene and being characterized by a third magnification and a third offset.

6. The method of claim 5 wherein said second time period is less than said first time period.

7. The method of claim 1 wherein said screen displays said first displayed scene when said touch gesture is terminated.

8. The method of claim 1 wherein said screen continues to display said second displayed screen when said touch gesture is terminated.

9. A non-transitory computer readable medium that stores instructions that cause a data processing system to execute a method that controls a screen in a data processing system to generate displays comprising portions of an underlying scene, said method comprising:
displaying on said screen a first displayed scene comprising a first portion of said underlying scene, said first displayed scene being characterized by a first magnification and a first offset relative to said underlying scene;
detecting a long touch gesture on said screen at a first location, said long touch gesture being characterized by a first time period, a first contact point on said screen, a second contact point on said screen, and a distance between said contact points; and
displaying a second displayed scene on said screen, said second displayed scene comprising a different portion of said underlying scene and being characterized by a second magnification that is greater than said first magnification if said distance is greater than a predetermined value and less than said first magnification if said distance is less than said predetermined value, said second displayed scene being displayed in response to said long touch gesture, said predetermined value being set prior to said long touch gesture being detected, and said second magnification being set prior to said long touch being detected.

10. The non-transitory computer readable medium of claim 9 wherein said second magnification changes continuously as long as said long touch gesture is maintained for a time longer than a predetermined time.

11. The non-transitory computer readable medium of claim 9 wherein said second displayed scene is characterized by a second offset that is determined by said long touch gesture.

12. The non-transitory computer readable medium of claim 11 wherein said second offset depends on said first displayed scene and said long touch gesture.

13. The non-transitory computer readable medium of claim 9 further comprising displaying a third displayed scene on said screen after a second time period if said long touch gesture is maintained for that second time period, said third displayed scene comprising a different portion of said underlying scene and being characterized by a third magnification and a third offset.

14. The non-transitory computer readable medium of claim 13 wherein said second time period is less than said first time period.

15. The non-transitory computer readable medium of claim 9 wherein said screen displays said first displayed scene when said long touch gesture is terminated.

16. The non-transitory computer readable medium of claim 9 wherein said screen continues to display said second displayed screen when said long touch gesture is terminated.
