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. A method, comprising:

at an electronic device having a display and a touch-sensitive surface;

displaying at least a portion of an electronic document that includes text that has a reading direction on the display;

detecting a gesture on the touch-sensitive surface, wherein the gesture includes movement in a first direction on the touch-sensitive surface that corresponds to a second direction on the display; and

in response to detecting the gesture;

in accordance with a determination that the second direction on the display includes a directional component that is opposite to the reading direction, performing a navigation operation; and

in accordance with a determination that the second direction on the display includes a directional component in the reading direction and that the gesture meets predefined criteria, performing an annotation operation.

2. An electronic device, comprising:

a display;

a touch-sensitive surface;

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 text that has a reading direction;

detecting a gesture on the touch-sensitive surface, wherein the gesture includes movement in a first direction on the touch-sensitive surface that corresponds to a second direction on the display; and

in response to detecting the gesture;

in accordance with a determination that the second direction on the display includes a directional component that is opposite to the reading direction, performing a navigation operation; and

in accordance with a determination that the second direction on the display includes a directional component in the reading direction and that the gesture meets predefined criteria, performing an annotation operation.

3. A graphical user interface on an electronic device with a display, a touch-sensitive surface, a memory, and one or more processors to execute one or more programs stored in the memory, the graphical user interface comprising:

at least a portion of an electronic document that includes text that has a reading direction;

wherein;

a gesture is detected on the touch-sensitive surface, wherein the gesture includes movement in a first direction on the touch-sensitive surface that corresponds to a second direction on the display; and

in response to detecting the gesture;

in accordance with a determination that the second direction on the display includes a directional component that is opposite to the reading direction, a navigation operation is performed; and

in accordance with a determination that the second direction on the display includes a directional component in the reading direction and that the gesture meets predefined criteria, an annotation operation is performed.

4. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with a display and a touch-sensitive surface, cause the device to:

display at least a portion of an electronic document that includes text that has a reading direction;

detect a gesture on the touch-sensitive surface, wherein the gesture includes movement in a first direction on the touch-sensitive surface that corresponds to a second direction on the display; and

in response to detecting the gesture;

in accordance with a determination that the second direction on the display includes a directional component that is opposite to the reading direction, perform a navigation operation; and

in accordance with a determination that the second direction on the display includes a directional component in the reading direction and that the gesture meets predefined criteria, perform an annotation operation.
