The touch input unit generates an input signal corresponding to one touch point on any one of the first, second and third operating areas, and outputs the input signal to the main module such that the main module performs an operation corresponding to the input signal.

Abstract: A capacitive pointing device includes a capacitive sensor unit, a switch unit, and an operating unit. The capacitive sensor unit has a receiving space receiving the switch unit, and a plurality of capacitive sensors disposed around the receiving space. The operating unit is spaced apart from the capacitive sensors, and is configured to result in a capacitance effect with the capacitive sensors. The operating unit is movable toward the capacitive sensor unit to trigger the switch unit, and is movable horizontally relative to the capacitive sensors. Capacitance variation between the operating unit and each of the capacitive sensors is used for determining a moving direction and an amount of movement of the operating unit.

Abstract: The present invention relates to an electronic device and a control method thereof. The control method includes the following steps of: determining whether a touch object contacts a touch surface; and determining whether the touch object contacts one touch area or sequentially contacts at least two touch areas. If the touch object contacts one touch area, an operation of the touch area is activated. If the touch object sequentially contacts at least two touch areas, a predetermined special function is activated. Accordingly, time for selecting the functions can be reduced and convenience can be enhanced during operation.
