5A to 5C are conceptual diagrams showing the forms of movement of the earset 200 as the user moves his or her head.

Referring to FIG. 5A, the user can rotate the head around the axis Z along the body extension direction. In other words, the head is rotated in position without deviating from the state of being placed along the body extension direction.

The earset 200 exhibits the same movement as the rotation of the head, which is sensed by the sensing unit 230. The control unit 210 may determine that the user expresses a negative intention with respect to such a motion.

Further, the rotation of the earset 200 with respect to the upper axis Z can be recognized as being of a reciprocating shape. In other words, as the earset 200 is rotated at the first position relative to the upper axis Z to reach the second position and then returns to the first position, the control unit 210 (Rotation) of the earset 200 with respect to the axis Z is determined.

Referring to FIG. 5B, the user can rotate the head around the axis X along the width direction (left / right direction) of the body. This behavior is usually expressed as nodding.

In response to this movement of the user, the earset 200 is also rotated about the axis X, and the movement of the earset 200 is sensed by the sensing unit 230. The control unit 210 receiving the motion from the sensing unit 230 may determine that the user expresses a positive intention.

The movement with respect to the axis X can also be recognized as the rotation of the earset 200 is in the form of a reciprocating motion.

Referring to FIG. 5C, the user can swing the head around the axis Y along the thickness direction (front / back direction) of the body. In response to the movement of the user, the earset 200 is rotated about the axis Y. [ When the motion is input from the sensing unit 230, the control unit 210 can determine that the user has displayed a question.

The movement with respect to the axis Y can also be recognized as the rotation of the earset 200 with respect to it is made in a reciprocating manner.

In the above description, only rotation about the axes (X, Y, Z) has been described by way of example, but the present invention is not limited thereto. The sensing unit 230 may be configured to detect a case where the earset 200 is translationally moved with respect to the axes X, Y,

Furthermore, when the above-described reciprocating motions are performed within a predetermined time interval, the control unit 210 can be configured to recognize the reciprocating motions. The above time interval can be less than 3 seconds.

6 is a flowchart illustrating an interaction between the portable terminal 100 and the earset 200 according to an embodiment of the present invention.

Referring to FIG. 5, when the portable terminal 100 receives text information, it is guided to the earset 200. Specifically, the portable terminal 100 receives the character information through the wireless communication unit 110 (FIG. 1) and transmits the character information to the communication unit 220 of the earset 200 through the terminal communication unit 114a (FIG. 7) . The control unit 210 connected to the communication unit 220 causes the speaker 250 to output the fact that the character information is received through the speaker 250. The user confirms the reception of the character information through the output of the speaker 250.

The user moves his / her head while wearing the earset 200, whereby the earset 200 is also moved with respect to one axis (X, Y, Z). The control unit 210 controls the earset 200 differently depending on which axis the movement of the earset 200 is made.

For example, if the earset 200 moves in the form as shown in FIG. 5A, or if the user does not react and the movement of the earset 200 is not input, the control unit 210 determines that the user does not intend to check the contents of the character information . In this case, the control unit 210 ends the guide process for the received character information.

Alternatively, when the user nods his / her head as shown in FIG. 5B and accordingly the rotation of the earset 200 with respect to the axis X is input to the control unit 210, the control unit 210 determines whether the user It can be judged that it wants to confirm. In this case, the contents of the character information converted into the voice by the character / voice conversion unit 260 are output through the speaker 250. [

The control unit 210 may change the output of the content of the character information through the speaker 250 and / or the character information itself if the additional movement of the earset 200 is detected during the output of the content of the character information, Can be achieved. The above additional motion may be a motion for the same axis as the motion in which the output of the content of the character information was originally made, or a motion for another axis.

For example, when the earset 200 moves in the form illustrated in FIG. 5B and the contents of the character information is output through the speaker 250, the earset 200 moves again in the form illustrated in FIG. 5B. . In this case, the control unit 210 can determine that the user understands the contents of the character information and can terminate the output thereof. Accordingly, the output of the contents of the corresponding character information is stopped, and guidance for the other character information can be made. Alternatively, the control unit 210 may be configured such that a guide for storing or deleting the corresponding character information is output through the speaker 250.

Unlike the above, while the content of the character information is output through the speaker 250, the control unit 210 can receive that the earset 200 moves in the form illustrated in FIG. 5A. In this case, the control unit 210 can determine that the user expresses the intention that the content of the corresponding character information should no longer need to be listened to. As a result, the control unit 210 can stop outputting the contents of the character information or delete the contents of the character information. In the case of deletion, the control unit 210 may cause the speaker 250 to output a message asking whether to delete the message, in order to confirm the user's intention. The location may be stored in the memory 280. It can be judged that the consent for the interest is made when the earset 200 is moved as shown in FIG. 5B, such as the consent for the voice output on the content of the character information.

If the earset 200 further moves in a specific form, for example, as shown in FIG. 5C, after the output of the content of the character information is interrupted, the controller 210 transmits a more positive action to the character information to the portable terminal 100 ). ≪ / RTI > For example, the number of the portable terminal or the like to which the character information is transmitted is registered in the portable terminal 100 as a number for blocking the reception.

If the user displays a question as shown in FIG. 5C during the output of the contents of the character information, the controller 210, which senses the movement of the earset 200, may cause the contents of the corresponding character information to be outputted again . This is in accordance with the intention of the user who could not understand the contents of the character information at a time.

When the output of the voice is completed, the vibration unit 270 of the earset 200 can generate vibration by the setting. By this vibration, the user can know that the output of the contents of the character information is completed. Further, the vibration may indicate that there is no character information to be outputted next.

If the telephone call is connected during the output of the contents of the character information as described above, the control unit 210 can determine whether or not to accept the telephone call by the specific movement of the earset 200. When the telephone conversation is terminated, the control unit 210 may cause the output of the character information to be resumed or the output of the earphone 200 to be resumed when the movement of the earset 200 is input.

When the movement of the casing 201 of the earset 200 is detected by the sensing unit 230, the movement of the portable terminal 100 or the earset 200 A guidance voice for the operation can be output. For example, if the user is guiding the reception of the character information as shown in FIG. 5B, the guidance voice may be output as 'I will output the contents of the character information'.

7 is a block diagram illustrating a case where a mobile terminal 100 communicatively connected to an earset 200 communicates with a navigation terminal 300 of a vehicle according to an embodiment of the present invention.

Referring to the drawings, the portable terminal 100 includes a vehicle communication unit 114b for communicating with the navigation terminal 300. [

The navigation terminal 300 includes a control unit 310 for controlling its operation and a navigation communication unit 320 for communicating with the vehicle communication unit 114b. The control unit 310 further includes a speed receiving unit 330 connected to the speed detecting unit for detecting the speed of the vehicle to receive the vehicle speed. Further, the navigation terminal 300 includes an interface unit 340 for mediating the operation of the vehicle such that the control unit 310 can operate the navigation terminal 300.

6, the output of the contents of the character information received by the portable terminal 100 is started by a specific movement of the earset 200. However, Can be followed.

For example, it is determined that the user of the portable terminal 100 wearing the earset 200 travels at a speed higher than a predetermined level. This is because the speed of the vehicle received through the speed receiving unit 330 of the navigation terminal 300 before the portable terminal 100 starts outputting the contents of the character information by the specific movement of the earset 200 And transmits it to the earset 200. The control unit 210 of the earset 200 may be configured to start outputting the contents of the character information after the speed of the vehicle is lowered to a certain level or lower. This is to reduce the influence of the process of receiving the contents of the character information on the operation of the vehicle.

The control unit 180 of the portable terminal 100 may transmit a signal instructing the navigation terminal 300 to lower the speed of the vehicle, in order to start outputting the content of the character information. The control unit 310 receiving the signal can control the operation of the engine of the vehicle through the interface unit 340 to lower the vehicle speed. Alternatively, the interface unit 340 may be connected to a vehicle light emitting means or a speaker. In this case, in order to inform the driver that the speed is to be reduced, the control unit 310 may cause the light emitting means to emit light or output a warning message through the speaker.

The control unit 180 can communicate with the navigation terminal 300 in response to the user's response after the contents of the character information through the speaker 250 of the earset 200 are output. For example, when a user is shocked by the contents of character information and makes a sound, the sound is input through the microphone 240 of the earset 200. The control unit 210 causes the sound to be transmitted to the portable terminal 100 and the control unit 180 instructs the control unit 310 of the navigation terminal 300 to control the vehicle in response to the current situation. Specifically, the control unit 310 of the navigation terminal 300 may reduce the speed of the vehicle through the interface unit 340 or may output a message requesting the driver to concentrate on the operation.
