Abstract

An electronic device with a display, a touch-sensitive surface, one or more processors, and memory detects a first portion of a gesture, and determines that the first portion has a first gesture characteristic. The device selects a dynamic disambiguation threshold in accordance with the first gesture characteristic. The dynamic disambiguation threshold is used to determine whether to perform a first type of operation or a second type of operation when a first kind of gesture is detected. The device determines that the gesture is of the first kind of gesture. After selecting the dynamic disambiguation threshold, the device determines whether the gesture meets the dynamic disambiguation threshold. When the gesture meets the dynamic disambiguation threshold, the device performs the first type of operation, and when the gesture does not meet the dynamic disambiguation threshold, the device performs the second type of operation.

Claims

1. (canceled)

2. A method performed at an electronic device having a display and a touch-sensitive surface, comprising:

displaying at least a portion of an electronic document that includes a first region;

detecting a gesture on the touch-sensitive surface, wherein the gesture comprises an initial portion comprising touchdown of a contact on the touch-sensitive surface, and a subsequent portion after the touchdown;

determining whether the initial portion of the gesture is detected at a location corresponding to the first region of the electronic document;

in response to determining that the initial contact of the gesture is detected at a location corresponding to the first region of the electronic document, selecting a first disambiguation threshold used to determine whether to perform navigation or annotation;

in response to detecting movement of the contact;

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture satisfies the first dynamic disambiguation threshold, performing a navigation operation on the electronic document; and

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture does not satisfy the first disambiguation threshold, performing an annotation operation on the electronic document.

3. The method of claim 2, wherein determining whether the initial contact of the gesture is detected at a location corresponding to the first region of the electronic document comprises determining whether the initial contact is detected at a location corresponding to text of the electronic document.

4. The method of claim 2, wherein the movement of the contact is a third portion of the gesture that occurs following the subsequent portion.

5. The method of claim 2, wherein the subsequent portion of the gesture comprises the contact being maintained at substantially the same location as the first portion of the gesture.

6. The method of claim 5, wherein the first disambiguation threshold is a first speed threshold.

7. The method of claim 6, wherein the first disambiguation threshold is satisfied when a speed of the subsequent portion of the gesture is greater than the dynamic disambiguation threshold speed.

8. The method of claim 6, wherein the first disambiguation threshold is not satisfied when a speed of the subsequent portion of the gesture is greater than the dynamic disambiguation threshold speed.

9. The method of claim 2, further comprising:

in response to determining that the initial contact of the gesture is detected at a location corresponding to a second region of the electronic document, selecting a second disambiguation threshold used to determine whether to perform navigation or annotation.

10. The method of claim 9, wherein the second disambiguation threshold is selected such that the range of values corresponding to an annotation operation is an empty set, the method further comprising:

in response to detecting movement of the contact, performing a navigation operation.

11. The method of claim 9, wherein determining whether the initial contact of the gesture is detected at a location corresponding to the second region of the electronic document comprises determining whether the initial contact is detected at a location not corresponding to text of the electronic document.

12. A portable multifunction 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;

displaying at least a portion of an electronic document that includes a first region;

detecting a gesture on the touch-sensitive surface, wherein the gesture comprises an initial portion comprising touchdown of a contact on the touch-sensitive surface, and a subsequent portion after the touchdown;

determining whether the initial portion of the gesture is detected at a location corresponding to the first region of the electronic document;

in response to determining that the initial contact of the gesture is detected at a location corresponding to the first region of the electronic document, selecting a first disambiguation threshold used to determine whether to perform navigation or annotation;

in response to detecting movement of the contact;

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture satisfies the first dynamic disambiguation threshold, performing a navigation operation on the electronic document; and

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture does not satisfy the first disambiguation threshold, performing an annotation operation on the electronic document.

13. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a portable multifunction device with a touch screen display, cause the device to:

display at least a portion of an electronic document that includes a first region;

detect a gesture on the touch-sensitive surface, wherein the gesture comprises an initial portion comprising touchdown of a contact on the touch-sensitive surface, and a subsequent portion after the touchdown;

determine whether the initial portion of the gesture is detected at a location corresponding to the first region of the electronic document;

in response to determining that the initial contact of the gesture is detected at a location corresponding to the first region of the electronic document, select a first disambiguation threshold used to determine whether to perform navigation or annotation;

in response to detecting movement of the contact;

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture satisfies the first dynamic disambiguation threshold, perform a navigation operation on the electronic document; and

in accordance with a determination that the initial portion of the gesture is detected at the first region of the electronic document and that the subsequent portion of the gesture does not satisfy the first disambiguation threshold, perform an annotation operation on the electronic document.
