TOUCH SCREEN DEVICE, METHOD, AND GRAPHICAL USER INTERFACE FOR MOVING ON- SCREEN OBJECTS WITHOUT USING A CURSOR

摘要

In some embodiments, an electronic device with a touch screen display: detects a single finger contact on the touch screen display; creates a touch area that corresponds to the single finger contact; determines a representative point within the touch area; determines if the touch area overlaps an object displayed on the touch screen display, which includes determining if one or more portions of the touch area other than the representative point overlap the object; connects the object with the touch area if the touch area overlaps the object, where connecting maintains the overlap of the object and the touch area; after connecting the object with the touch area, detects movement of the single finger contact; determines movement of the touch area that corresponds to movement of the single finger contact; and moves the object connected with the touch area in accordance with the determined movement of the touch area.
