Abstract

An electronic device with a display and a touch-sensitive surface displays a plurality of user-selectable objects. A respective user-selectable object has a corresponding activation region on the touch-sensitive surface with an activation region size. The activation region size has a respective default size when a representative point for a finger contact is located outside the activation region. The activation region size has a respective expanded size when the representative point is located within the activation region. The device: detects movement of the finger contact across the touch-sensitive surface; in response, changes the size of the activation region for the respective user-selectable object between the respective default size and the respective expanded size in accordance with the movement of the finger contact; detects a user input when the representative point is located within the activation region for the respective user-selectable object; and, in response, performs a predefined operation.

and
the activation region size for the respective user-selectable object has a respective expanded size, larger than the respective default size, when the representative point for the finger contact is located within the activation region for the respective user-selectable object;
detecting movement of the finger contact across the touch-sensitive surface;
in response to detecting movement of the finger contact across the touch-sensitive surface, changing the size of the activation region for the respective user-selectable object between the respective default size and the respective expanded size in accordance with the movement of the finger contact;
detecting a user input when the representative point for the finger contact is located within the activation region for the respective user-selectable object;
and,
in response to detecting the user input when the representative point for the finger contact is located within the activation region for the respective user-selectable object, performing a predefined operation associated with the respective user-selectable object.
