  • Patent number: 8665225
    Abstract: A portable device with a touch screen display detects a finger-in-contact event at a first position on the touch screen display and identifies a user interface object associated with the first position. The portable device determines whether the identified user interface object is moveable across the touch screen display. For an identified object that is determined to be moveable across the touch screen display, the portable device detects a sequence of one or more first finger-dragging, a first finger-out-of-contact, one or more second finger-dragging, and a first finger-out-of-range events and performs a first operation associated with the identified moveable user interface object at least in part in accordance with the first and second finger-dragging events. For an identified not moveable object, the portable device detects a second finger-out-of-contact event and performs a second operation, different from the first operation in response to a second finger-out-of-contact event.
