Abstract: A system comprises a touchscreen, at least one touch control unit, a first controller, and a second controller, where the touch control unit includes a detection electrode, an induction electrode, and a conducting wire that connects the detection electrode and the induction electrode, where the detection electrode is located outside a touch control area of the touchscreen, the induction electrode is located in the touch control area of the touchscreen, and the induction electrode is coupled to at least one capacitance node in the touchscreen, and the first controller is separately connected to the touchscreen and the second controller. A touch control operation performed by a user on the detection electrode disposed outside the touchscreen is identified using an existing capacitance node in the touchscreen, and the terminal is controlled according to the touch control operation.
