Referring to FIG. 24, the portable terminal 200 may include a magnetometer. After recognizing the contact direction using the magnetic field sensor, the information about the contact direction is displayed on the display device 100, Lt; / RTI >

For example, as shown in FIG. 24, the portable terminal 200 determines that the contact direction is the front when the output value of the magnetic field sensor indicates 108 degrees or more, (100).

In this case, the display apparatus 100 requests the portable terminal 200 to transmit the content according to the received contact direction information when the portable terminal 200 is contacted, and receives the content data selected by the portable terminal 200 .

Meanwhile, when the output value of the magnetic field sensor indicates less than 108 degrees, the portable terminal 200 may determine that the contact direction is the back face, and transmit the information that the contact direction is the back face to the display device 100. [

In this case, the display device 100 may transmit the content data to the portable terminal 200 according to the received contact direction information when the portable terminal 200 is contacted.

The contact direction of the recognized portable terminal 200 as described above may be stored and managed in the display device 100 together with the portable terminal identification information (ID) as shown in Table 1 below.

ID Orientation 10 Front 21 back side 51 Front

 Referring to FIG. 25, the portable terminal 200 may include an accelerometer, and can recognize the contact direction using the output value of the acceleration sensor.

For example, as shown in FIG. 25, the values measured by the acceleration sensor along the axis along which the portable terminal 200 moves are different from each other in the case where the contact direction is the front side and the case where the rear side is opposite The portable terminal 200 can recognize the contact direction using the output value of the acceleration sensor.

26, the portable terminal 200 can recognize the direction of contact with the display device 100 by using the proximity sensors 320 and 321 provided on the front face 200F and the rear face 200R, respectively .

For example, when the front surface of the portable terminal 200 touches the screen 181 of the display device 100, the proximity sensor 320 provided on the front surface 200F of the portable terminal 200 may approach the object When the rear surface of the portable terminal 200 touches the screen 181 of the display device 100, the proximity sensor 321 provided on the rear surface 200R of the portable terminal 200 approaches the object Can be detected.

Referring to FIG. 27, the portable terminal 200 can recognize a contact direction to the display device 100 using a gyroscope sensor.

The gyro sensor is provided in each of the display device 100 and the portable terminal 200 and the display device 100 receives the specific value of the gyro sensor provided in the portable terminal 200 from the portable terminal 200, The contact direction of the portable terminal 200 can be recognized by comparing with the measured value of the sensor.

That is, the display device 100 includes an xyz axis g1 indicating the direction of the display device 100 detected by the gyro sensor provided in the portable terminal 200 and an xyz axis g1 indicating the direction of the display device 100 detected by the gyro sensor provided in the portable terminal 200 The xyz axis g2 indicating the direction of the contact surface 200 may be compared with each other to determine the contact direction.

For example, when the specific values of the gyro sensors provided in the display device 100 and the portable terminal 200 match each other, the display device 100 can determine that the rear surface of the portable terminal 200 is in contact have.

On the other hand, when the xyz axis g1 indicating the direction of the display device 100 and the xyz axis g2 indicating the direction of the portable terminal 200 differ by about 180 degrees on either axis, It can be determined that the front surface of the portable terminal 200 is in contact with the user.

When the xyz axis g1 indicating the direction of the display device 100 and the xyz axis g2 indicating the direction of the portable terminal 200 are different from each other, It can be judged that it is contacted.

28, the portable terminal 200 can sense the direction of contact with the display device 100 using the light sensing sensor 330. The light sensing sensor 330 senses an ambient light sensor (ALS, Ambient Light Sensor) or a colorimeter.

For example, the portable terminal 200 transmits the measured color information through the light sensing sensor 330 provided on the front surface 200F to the display device 100 together with the identification information (ID) of the portable terminal, The device 100 can compare the color information of the displayed image at the time when the portable terminal 200 is contacted with the color information received from the portable terminal 200 to determine the contact direction.

29, when the front surface of the portable terminal 200 touches the screen of the display device 100, the light sensor 330 provided on the front surface 200F of the portable terminal 200 displays the light 100 may be detected so that the color information measured by the photo sensor 330 and the color information of the image displayed on the display device 100 may coincide with each other.
