发明名称 TOUCHSCREEN GESTURES FOR SELECTING A GRAPHICAL OBJECT
摘要 A two-finger selection method is implemented on a touchscreen of an electronic device. One embodiment involves sensing the touch positions of two fingers on the touchscreen. In response to sensing the two simultaneous touch positions, a selection graphic is displayed and dynamically positioned on the touchscreen as a function of the two touch positions. A specific graphical object, such as a command button having an associated function, is selected in response to a separate selection input received while the selection graphic is positioned on the specific graphical object.
