13 is a flowchart showing another example of the method of driving a mobile terminal according to the present invention. Hereinafter, the mobile terminal driving method will be described with reference to necessary drawings.

First, the control unit 180 controls the camera 121 to acquire an image of a specific place (S300). Then, the control unit 180 displays the image of the specific place on the touch screen 151 as a preview screen (S310).

Then, a touch on a specific place in the preview screen is received (S320). Then, the control unit 180 generates a control signal for performing a predetermined function (i.e., cleaning for a specific place) to correspond to the specific location, and then transmits the generated control signal to the robot cleaner S330).

The transmission of the generated control signal may be performed through a short-range wireless communication link formed between the mobile terminal 100 and the robot cleaner. The robot cleaner having received the control signal can perform a cleaning function for a specific place in response to a control signal. The location information about the specific place may be stored in advance.

FIG. 14 shows an example in which the operation of the robot cleaner 600 is controlled according to the mobile terminal driving method shown in FIG. 14A shows that the user touches the preview screen in a state in which the preview image for the specific place is displayed on the mobile terminal 100. FIG.

Then, the mobile terminal 100 generates a control signal for cleaning the specific location and transmits the control signal to the robot cleaner 600. Referring to FIG. 14 (b), the robot cleaner 600 can clean a specific place in response to a control signal.

According to the mobile terminal driving method described with reference to FIGS. 13 and 14, the user can wirelessly control the robot cleaner 600 based on the touch operation of the mobile terminal 100 on the preview screen.

Each of the mobile terminal driving methods according to the present invention may be implemented in a form of a program that can be executed through various computer means and recorded in a computer readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination.
