Accordingly, the control unit 12 of the first communication device 10 activates the operation of the two-dimensional sensing unit 11, so that the two-dimensional sensing unit 11 detects the user's two-dimensional stroke (step S32). When the dimension detecting unit 11 is implemented as a touch pad, a track ball, or a mouse, a two-dimensional stroke of the user is detected by detecting a continuous change value of the X-axis and Y-axis coordinate values according to the user's finger movement. When the sensing unit 11 is implemented as a gyroscope, the user grips the first communication device 10 by hand and detects a continuous change value of the X-axis and Y-axis coordinate values according to the movement, thereby the user's two-dimensional stroke.

In addition, the two-dimensional sensor 11 generates a X-axis and a Y-axis detection signal corresponding to the stroke while transmitting the two-dimensional stroke of the user to the control unit 12 (step S33), where the two-dimensional detection The unit 11 transmits the corresponding X-axis and Y-axis detection signals to the controller 12 as a digital signal type. Accordingly, the controller 12 wirelessly transmits the stroke information, which is a combination of the X-axis and Y-axis detection signals, to the second communication device 20 through the transceiver 13 (step S34).

Meanwhile, the transceiver 21 of the second communication device 20 wirelessly receives stroke information including a combination of X- and Y-axis detection signals transmitted wirelessly from the transceiver 13 of the first communication device 10.

Accordingly, the control unit 22 analyzes the stroke information composed of the combination of the X-axis and Y-axis detection signals to detect the change in stroke position and direction (step S36), and the user's two-dimensional stroke using the corresponding stroke position and direction change. The command is recognized (step S37).

The control unit 22 then controls the application processing unit 23 according to the recognized two-dimensional stroke command of the user to process the corresponding application function (step S38). At this time, the application processor 23 processes the corresponding application function under the control of the controller 22, for example, a camera mode switching function according to a stroke command for entering the camera mode, and transmits camera image information in an emergency situation.

The two-dimensional sensor 11 detects the user's stroke in two dimensions, and divides the plane of the stroke made by the user into an area from '1' to '9' as shown in FIG. If one is assumed, the area '5' is the center point, that is, the coordinate (X, Y) = (0,0), and the area '1' is (-1,1) and the area '2' is (0,1). ), Area '3' is (1,1), area '4' is (-1,0), area '6' is (1,0), area '7' is (-1, -1), area '8' may be defined as (0, -1) and region '9' as (1, -1). Here, the number of each area does not mean itself, but has a meaning as a stroke point (position) with respect to the center point, and '0, 1, -1' used as X and Y axis detection values are strokes. A value having a meaning for indicating the position and direction of may be changed to another value.

When the user operates the mode switching unit 24 of the second communication device 20 to activate the two-dimensional stroke command function, the first communication device 10 performing near field communication with the second communication device 20.

'Indicating the camera image emergency transmission command. In response to the camera image emergency transmission command, which is a recognized stroke command, the controller recognizes that the camera-related application module of the application processor 23 transmits a camera image informing of a corresponding emergency situation.

In addition, the user may rotate the camera image through a user stroke command while the user performs the camera function in the second communication device 20. For this purpose, the user corresponds to the letter 'U' indicating a command for rotating the camera image. In the case where the stroke is performed to move the area '1-4-7-8-9-6-3' in order as shown in FIG. 4 (D), the two-dimensional sensing unit 11 performs the corresponding stroke point. By generating the X-axis and Y-axis detection signal corresponding to the sequentially transmitted to the control unit 12, the control unit 12 transmits the stroke information consisting of the corresponding X-axis and Y-axis detection signal through the transmission and reception unit 13 Wireless transmission to the device 20.
