Humidity can have absolute humidity and relative humidity, and the sensing unit can sense absolute humidity. The relative humidity can be calculated using absolute humidity and temperature. Hereinafter, embodiments of the present invention will be described using relative humidity, but it is apparent that absolute humidity can be used.

The step S304 is a step of sensing a human's breathing, and a method of sensing a human's breath uses a sensed humidity and a temperature. That is, in step S304, if the humidity is equal to or higher than the first value and the temperature is equal to or higher than the second value, the control unit proceeds to step S305. Otherwise, the control unit returns to step S301. A specific method of sensing the human's breathing will be described in detail below with reference to FIG. 4 and FIG.

In step S305, when a sound is detected while the display is turned off, the display is turned on and the voice recognition mode is activated (S306). If the display is on, the control method moves to step S307.

In step S307, the control unit proceeds to step S308 if the call signal is being received. In step S308, the control unit connects the call signal and activates the whisper mode. Steps S307 and S308 will be described in detail below with reference to FIG.

In step S309, if the controller is in a busy state, the process proceeds to step S310. In step S310, the controller controls input and output of sound. The control for controlling the input / output of sound by detecting the user's breathing during the conversation will be described in detail with reference to Fig.

FIG. 4 is a diagram illustrating the operation of a mobile terminal by recognizing a person's breathing according to an embodiment of the present invention. According to an embodiment of the present invention, the mobile terminal 100 can sense the humidity and the temperature to recognize the user's 401, and the user 401 can control the mobile terminal 100 using the incoming have. In FIG. 4A, the state of the mobile terminal 100 is a state in which the display is turned off. In this state, the user 401 can input 402 the position of the humidity sensor and the temperature sensor of the mobile terminal 100. Since the position of the humidity sensor and the temperature sensor may be different according to the mobile terminal 100, the user 401 assumes that the bell 402 is divided into the position of the humidity sensor and the temperature sensor of the mobile terminal 100 . Generally, when the user touches the mobile terminal 100, the humidity and the temperature sensed by the humidity sensor and the temperature sensor instantaneously rise because the humidity and the temperature are high. The change in humidity and temperature will be described with reference to FIG.

5 is a graph showing the change in humidity and temperature sensed when a person's breath is blown to a humidity sensor and a temperature sensor. FIG. 5 (a) is a view showing a change in temperature sensed by a temperature sensor according to time, and FIG. 5 (b) is a diagram showing a change in humidity sensed by a humidity sensor according to time. The control unit 180 can detect that the input of the person is inputted when the humidity sensed by the humidity sensor is equal to or higher than the first predetermined value 502 and the temperature sensed by the temperature sensor is equal to or higher than the second predetermined value 501. [

Referring to FIG. 5, a human's breath was blown into the sensors four times, and the breathing occurred at 1250 [ms], 1335 [ms], 1365 [ms] and 1395 [ms]. Looking at the changes in the temperature and the humidity of each of the four times, it can be seen that the temperature and the humidity suddenly rise suddenly. In addition, in all four cases, it can be confirmed that the temperature exceeded the second predetermined value 501 has been increased, and that the change in the humidity has also increased in all cases by the first predetermined value 502 or more. Therefore, the controller 180 can detect that the input of the human being is input by using the temperature sensor and the humidity sensor, if the two values of temperature and humidity are more than predetermined values.

Returning to FIG. 4, FIG. 4B is a view showing an activated screen of the voice recognition mode by turning on the display that has been turned off when the mobile terminal 100 senses the incoming 402. Here, the voice recognition mode means a state in which a voice of a user of the mobile terminal is recognized and a predetermined function of the terminal can be executed. In this case, it is obvious that when detecting the bell 402, it is possible to perform not only the voice recognition mode but also any other function according to the setting of the mobile terminal 100.

Therefore, according to an embodiment of the present invention, the user 401 of the mobile terminal 100 can easily execute the voice recognition mode without performing any operation to execute the voice recognition mode of the mobile terminal 100. [

The mobile terminal 100 of FIG. 6 (a) is a diagram showing a screen on which a call signal is received. 6 (a), the mobile terminal 100 receives a telephone call from a person named Kim Tae-hee.

In some cases, the user 401 may be in a special situation when the telephone is being received as above. For example, there may be situations where the user 401 is in a meeting or needs to be called at a quiet library. If you receive a call in this case, the voice of the other party spreads in a quiet space, which can harm others. Therefore, in this situation, the user 401 may desire to receive a telephone call with the whisper mode being automatically set when the telephone is received.

FIG. 6 (b) is a diagram illustrating a call in a whisper mode automatically when a telephone call is received in step 402. In this case, the whisper mode means a mode having a setting for receiving a call in a quiet space, specifically, it can amplify its own voice and reduce the voice size of the calling party. That is, it means a mode in which the electric signal converted by the microphone is amplified and output through the wireless communication unit, and the electric signal received through the wireless communication unit is attenuated and output to the sound output unit. When the user makes a call while the whispers mode is set, the user 401 does not need to worry about the voice of the other party in a quiet space. Even if the user 401 calls with a small voice, the user can accurately communicate the content It will be possible.

As shown in FIG. 6, the user 401 can utilize the incoming call as one control input, so that the use of the incoming call makes the control of the mobile terminal 100 more convenient.

7 is a diagram illustrating a method for improving call quality using temperature and humidity detected during a call using a mobile terminal. Referring to FIG. 7, the user 401 uses the mobile terminal 100 to make a call. 7 (a) shows a case where the distance between the mouth of the user 401 and the mobile terminal 100 is d1, and Fig. 7 (b) shows the case where the distance is d2. far.

In some cases, the user 401 of the mobile terminal may make a call in a very noisy environment. For example, a call can be performed using a mobile terminal at a club, a night, or a concert hall. In this case, the other end of the call may be difficult to accurately hear the user 401 of the mobile terminal 100. In particular, when the distance between the mobile terminal 100 and the user 401 is long as shown in FIG. 7 (a) It is difficult to do.

In this case, as shown in FIG. 7 (b), the user 401 can bring the microphone of the mobile terminal 100 to his or her mouth. When the microphone of the mobile terminal 100 is taken to the mouth of the user, it is possible to clearly convey the voice of the user to the other party of the call.

Furthermore, if the user 401 takes the microphone to his / her mouth as shown in FIG. 7 (b), he / she can more clearly convey his / her voice if it can detect and amplify the user's voice.

That is, when the temperature sensor and the humidity sensor are positioned near the microphone of the mobile terminal 100, the temperature and humidity sensed by the user 401 when the user brings the mouth to the microphone can be raised. Accordingly, the controller 180 can detect that the mouth of the user is close to the microphone when the humidity and temperature values are higher than a predetermined value. If the control unit 180 detects that the user's mouth and the microphone are close to each other, the control unit 180 can amplify the voice of the user and transmit the voice to the calling party.

As a result, when the user 401 wants to amplify his / her voice according to the situation of a call, he / she can place his / her mouth close to the microphone of the mobile terminal 100 and talk. Therefore, according to the embodiment of the present invention, it is advantageous to amplify the voice by simply positioning the mouth of the user to the microphone without any other operation.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded.
