Abstract

In accordance with some embodiments, a computer-implemented method for use in conjunction with a device with a touch screen display is disclosed. In the method, a multifinger twisting gesture is detected on or near the touch screen display. The multifinger twisting gesture has a corresponding degree of rotation. A 90° screen rotation command is executed if the corresponding degree of rotation exceeds a predefined degree of rotation. A screen rotation command with an acute angle of rotation is executed and, upon ceasing to detect the multifinger twisting gesture, a screen rotation command with an angle of rotation opposite to the acute angle is executed if the corresponding degree of rotation is less than the predefined degree of rotation.

Claims

1. A device, comprising:

a touch screen display;

one or more processors;

memory; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for;

detecting a multifinger twisting gesture on or near the touch screen display, wherein the multifinger twisting gesture has a corresponding degree of rotation;

executing a 90°

screen rotation command, if the corresponding degree of rotation exceeds a predefined degree of rotation; and

executing a screen rotation command with an acute angle of rotation and executing, upon ceasing to detect the multifinger twisting gesture, a screen rotation command with an angle of rotation opposite to the acute angle, if the corresponding degree of rotation is less than the predefined degree of rotation.

2. The device of claim 1, wherein the device is a portable multifunction device.

3. The device of claim 1, wherein the multifinger twisting gesture is detected on the touch screen display.

4. The device of claim 1, wherein the multifinger twisting gesture is a two-finger gesture.

5. The device of claim 1, wherein the multifinger twisting gesture comprises simultaneous rotation of two thumbs.

6. The device of claim 1, wherein executing the 90°

screen rotation command results in display of a digital image in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the digital image in a portrait orientation.

7. The device of claim 1, wherein executing the 90°

screen rotation command results in display of an electronic document in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the electronic document in a portrait orientation.

8. A computer-implemented method, comprising:

at a device with a touch screen display;

detecting a multifinger twisting gesture on or near the touch screen display, wherein the multifinger twisting gesture has a corresponding degree of rotation;

executing a 90°

screen rotation command, if the corresponding degree of rotation exceeds a predefined degree of rotation; and

executing a screen rotation command with an acute angle of rotation and executing, upon ceasing to detect the multifinger twisting gesture, a screen rotation command with an angle of rotation opposite to the acute angle, if the corresponding degree of rotation is less than the predefined degree of rotation.

9. The computer-implemented method of claim 8, wherein the device is a portable multifunction device.

10. The computer-implemented method of claim 8, wherein the multifinger twisting gesture is detected on the touch screen display.

11. The computer-implemented method of claim 8, wherein the multifinger twisting gesture is a two-finger gesture.

12. The computer-implemented method of claim 8, wherein the multifinger twisting gesture comprises simultaneous rotation of two thumbs.

13. The computer-implemented method of claim 8, wherein executing the 90°

screen rotation command results in display of a digital image in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the digital image in a portrait orientation.

14. The computer-implemented method of claim 8, wherein executing the 90°

screen rotation command results in display of an electronic document in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the electronic document in a portrait orientation.

15. A computer readable storage medium having stored therein instructions, which when executed by a device with a touch screen display, cause the device to:

detect a multifinger twisting gesture on or near the touch screen display, wherein the multifinger twisting gesture has a corresponding degree of rotation;

execute a 90°

screen rotation command, if the corresponding degree of rotation exceeds a predefined degree of rotation; and

execute a screen rotation command with an acute angle of rotation and, upon ceasing to detect the multifinger twisting gesture, execute a screen rotation command with an angle of rotation opposite to the acute angle, if the corresponding degree of rotation is less than the predefined degree of rotation.

16. The computer readable storage medium of claim 15, wherein the device is a portable multifunction device.

17. The computer readable storage medium of claim 15, wherein the multifinger twisting gesture is detected on the touch screen display.

18. The computer readable storage medium of claim 15, wherein the multifinger twisting gesture comprises simultaneous rotation of two thumbs.

19. The computer readable storage medium of claim 15, wherein executing the 90°

screen rotation command results in display of a digital image in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the digital image in a portrait orientation.

20. The computer readable storage medium of claim 15, wherein executing the 90°

screen rotation command results in display of an electronic document in a landscape orientation and executing the screen rotation command with the angle of rotation opposite to the acute angle results in display of the electronic document in a portrait orientation.
