Portable multifunction device, method, and graphical user interface for interpreting a finger gesture on a touch screen display

摘要

A portable electronic device (100) having a touch screen display (112) detects a first finger-down event at a first position (5805) on the touch screen display (112). The first position. (5805) is adjacent to first and second user interface objects (5806, 5802). The portable device (100) detects a second finger event at a second position (5808,5812,5809,5817,5807) on the touch screen display (112). The second finger event is either a finger-dragging event or a finger-up event. The portable device (100) determines a type of the second finger event and a distance between the first position (5805) and the second position (5808,5812,5809,5817,5807). The portable device (100) performs a first action associated with the first user interface object (5806) if the distance is greater than a predefined threshold and performs a second action associated with the second user interface object (5802) if the distance is equal to or less than the predefined threshold and the second finger event is a finger-up event.
