An electronic device includes a touch panel with a touch area and a command button and includes an independent input mode and a dual input mode. In addition, a control method of an electronic device includes steps of: receiving touch data; determining whether the dual input mode needs to be executed or not, according to the touch data, executing the dual input mode when the dual input mode is determined to be executed, and executing the independent input mode when the dual input mode is not determined to be executed; and determining whether the touch panel is operated within a preset time or not, after executing the dual input mode, considering the touch data as a gesture input when the touch panel is determined as being used within a preset time, and switching to the independent input mode if not.
