Abstract

An electronic device with a touch screen display is provided. Content in a user interface is displayed at a first magnification, and in response to detecting a first multi-finger gesture on the touch screen display (e.g., a three-finger tap gesture), a first portion of the content is magnified to a second magnification, greater than the first magnification. Further, while displaying the first portion of the content in the user interface at the second magnification, the device may detect a second multi-finger gesture on the touch screen display (e.g., movement of a three-finger contact on the display). In response to this movement, the device performs panning the user interface, so that a second portion of the content, different from the first portion, is displayed on the touch screen at the second magnification.

First claim

What is claimed is:

1. An accessibility method, comprising:
at an electronic device with a touch screen display:
displaying content in a user interface at a first magnification on the touch screen display;
detecting a first multi-finger gesture at a location on the touch screen display, wherein detecting the first multi-finger gesture includes detecting concurrent multi-finger contacts on the touch screen display; and
in response to detecting the first multi-finger gesture on the touch screen display:
in accordance with a determination that the first multi-finger gesture ends with a liftoff of the concurrent multi-finger contacts occurring without more than a threshold amount of movement on the touch screen display, magnifying a first portion of the content in the user interface to a second magnification, greater than the first magnification, on the touch screen display, wherein the second magnification is a predefined magnification, and wherein the first portion of the content to be magnified in response to detecting the first multi-finger gesture on the touch screen display is determined based on the location of the first multi-finger gesture on the touch screen display; and
in accordance with a determination that the first multi-finger gesture includes more than the threshold amount of movement on the touch screen display, magnifying the first portion of the content in the user interface to a third magnification, greater than the first magnification, on the touch screen display, wherein the third magnification is selected based on a magnitude of the movement of the first multi-finger gesture, and wherein the first portion of the content to be magnified in response to detecting the first multi-finger gesture on the touch screen display is determined based on the location of the first multi-finger gesture on the touch screen display.

2. The method of claim 1 , further comprising:
while displaying the first portion of the content in the user interface at the second magnification or the third magnification, detecting a second multi-finger gesture on the touch screen display; and
in response to detecting the second multi-finger gesture on the touch screen display, panning the user interface in accordance with the second multi-finger gesture, so that a second portion of the content, different from the first portion, is displayed on the touch screen at the second magnification or the third magnification, wherein the second portion of the content is selected based on a magnitude of movement of the second multi-finger gesture on the touch screen display.

3. The method of claim 2 , wherein the second multi-finger gesture is a three-finger drag gesture on the touch screen display.

4. The method of claim 2 , including:
while displaying a second portion of the content in the user interface at the second magnification or the third magnification on the touch screen display:
detecting a third multi-finger gesture on the touch screen display, wherein detecting the third multi-finger gesture includes detecting concurrent multi-finger contacts on the touch screen display; and
in response to detecting the third multi-finger gesture on the touch screen display:
in accordance with a determination that the third multi-finger gesture ends with a liftoff of the concurrent multi-finger contacts occurring without more than a threshold amount of movement on the touch screen display, demagnifying the second portion of the content in the user interface to a fourth magnification on the touch screen display; and
in accordance with a determination that the third multi-finger gesture includes more than the threshold amount of movement on the touch screen display, demagnifying the second portion of the content in the user interface to a fifth magnification on the touch screen display, wherein the fifth magnification is selected based on a magnitude of the movement of the third multi-finger gesture.

5. The method of claim 4 , wherein the third multi-finger gesture includes a three-finger tap gesture.

6. The method of claim 4 , wherein the determination that the third multi-finger gesture ends with a liftoff of the concurrent multi-finger contacts occurring without more than a threshold amount of movement on the touch screen display includes a determination that the third multi-finger gesture is a three-finger, double-tap gesture.

7. The method of claim 4 , wherein the third multi-finger gesture is the same as the first multi-finger gesture.

8. The method of claim 4 , wherein demagnifying the content in the user interface includes displaying a zooming-out animation.

9. The method of claim 4 , wherein the fourth magnification corresponds to a default unmagnified view.

10. The method of claim 4 , wherein the fourth magnification corresponds to the first magnification.

11. The method of claim 4 , wherein detecting the third multi-finger gesture includes:
detecting a first touchdown of a respective number of contacts on the touch screen display, wherein the respective number of contacts is greater than one;
detecting a first liftoff of the respective number of contacts from the touch screen display; and
detecting a second touchdown of the respective number of contacts on the touch screen display.

12. The method of claim 11 , wherein:
the third multi-finger gesture includes detecting a second liftoff of the respective number of contacts;
the determination that the third multi-finger gesture ends with the liftoff of the concurrent multi-finger contacts occurring without more than the threshold amount of movement on the touch screen display includes a determination that the second liftoff of the respective number of contacts from the touch screen display was detected without more than the threshold amount of movement being detected; and
the determination that the third multi-finger gesture includes more than the threshold amount of movement on the touch screen display includes a determination that the threshold amount of movement was detected after detecting the second touchdown of the respective number of contacts on the touch screen display and before the second liftoff of the respective number of contacts from the touch screen display was detected.

13. The method of claim 4 , wherein the third multi-finger gesture includes movement in a direction towards a bottom of the touch screen display until the fifth magnification is reached.

14. The method of claim 1 , wherein the first magnification corresponds to a default unmagnified view.

15. The method of claim 1 , wherein the first multi-finger gesture includes a three-finger tap gesture.

16. The method of claim 1 , wherein the determination that the first multi-finger gesture ends with a liftoff of the concurrent multi-finger contacts occurring without more than a threshold amount of movement on the touch screen display includes a determination that the first multi-finger gesture is a three-finger, double-tap gesture.

17. The method of claim 1 , wherein detecting the first multi-finger gesture includes:
detecting a first touchdown of a respective number of contacts on the touch screen display, wherein the respective number of contacts is greater than one;
detecting a first liftoff of the respective number of contacts from the touch screen display; and
detecting a second touchdown of the respective number of contacts on the touch screen display.

18. The method of claim 17 , wherein:
the first multi-finger gesture includes detecting a second liftoff of the respective number of contacts;
the determination that the first m
