Recently, many industrial fields have been developing methods for using a sensor that detects humidity or temperature. Hereinafter, a mobile terminal using a sensor for sensing humidity or temperature (hereinafter, referred to as a humidity sensor and a temperature sensor) and a method of controlling the mobile terminal will be described.

3 is a flowchart illustrating a flow chart according to an embodiment of the present invention. In operation S301, the sensing unit may detect humidity and temperature. Meanwhile, the humidity may include absolute humidity and relative humidity, and the sensing unit may sense absolute humidity. The relative humidity can be calculated using absolute humidity and temperature. Embodiments of the present invention are described below using relative humidity, but it is obvious that absolute humidity can be used.

Step S304 is a step of detecting a person's breath, the method of detecting a person's breath using the detected humidity, temperature. That is, in step S304, the control unit moves to step S305 when the humidity is greater than or equal to the first value and the temperature is greater than or equal to the second value, and otherwise, returns to step S301. A detailed method of detecting a person's breath will be described in detail below with reference to FIGS. 4 and 5.

S305 turns on the display and activates the voice recognition mode when the input is detected while the display is turned off (S306). If the display is turned on, the control method moves to step S307.

In step S307, the controller moves to step S308 when 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, the control unit moves to step S310, and in step S310 the control unit controls the input and output of sound. The control of adjusting the input / output of the sound by detecting the user's breathing during the call will be described in detail with reference to FIG. 7.

4 is a diagram illustrating execution of a function 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 may detect humidity and temperature in order to recognize breathing of the user 401, and the user 401 may control the mobile terminal 100 by using breathing. 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 may blow on the position of the humidity sensor and the temperature sensor of the mobile terminal 100. Since the location of the humidity sensor and the temperature sensor may be different according to the mobile terminal 100, it is assumed that the user 401 blows the breathing 402 at the location of the humidity sensor and the temperature sensor of the mobile terminal 100. . In general, a person's breathing is high in humidity and temperature, so when the breathing 402 contacts the mobile terminal 100, the humidity and temperature sensed by the humidity sensor and the temperature sensor are momentarily increased. Accordingly, the change in humidity and temperature will be described with reference to FIG. 5.

5 is a diagram illustrating changes in humidity and temperature detected when a person's breath is blown onto a humidity sensor and a temperature sensor. Figure 5 (a) is a view showing the change in temperature detected by the temperature sensor with time, Figure 5 (b) is a view showing the change in humidity detected by the humidity sensor with time. If the humidity detected by the humidity sensor is greater than or equal to the first predetermined value 502 and the temperature detected by the temperature sensor is greater than or equal to the second predetermined value 501, the controller 180 may detect that human breath is input.

Referring to FIG. 5, a person's breath was blown four times on the sensors and blown at 1250 [ms], 1335 [ms], 1365 [ms] and 1395 [ms]. Looking at the changes in the temperature and humidity of each of the four times, it can be seen that the temperature and humidity increase suddenly. In addition, when looking at the change in temperature, it can be confirmed in all four cases that the temperature has risen by more than the second predetermined value 501, and in all four cases, the change in humidity can be confirmed that the temperature has risen by more than the first predetermined value 502. Therefore, the controller 180 may sense that the breathing of the person has been input by using both the temperature sensor and the humidity sensor when both the temperature and the humidity indicate more than a predetermined value.

4 (b) is a diagram illustrating an activation screen of the voice recognition mode after turning on the display that is turned off when the mobile terminal 100 detects the breathing 402. Here, the voice recognition mode refers to a state in which a voice of a user of the mobile terminal can be recognized to execute a predetermined function of the terminal. In this case, when detecting the breathing 402, it is obvious that not only the voice recognition mode is activated, but also other functions may be performed according to the setting of the mobile terminal 100.

Therefore, according to an exemplary embodiment of the present invention, the user 401 of the mobile terminal 100 may execute the voice recognition mode by simply blowing on it to perform the voice recognition mode of the mobile terminal 100.

6 is a diagram illustrating execution of a function by recognizing a user's breathing according to another embodiment of the present invention. The mobile terminal 100 of FIG. 6A illustrates a screen on which a call signal is being received. According to FIG. 6 (a), the mobile terminal 100 receives a call from a person named Tae-hee.

In some cases, the user 401 may be in a special situation when a call is being received as above. For example, there may be a situation where the user 401 is in a meeting or needs to answer a call in a quiet library. In this case, when you receive a call, the other party's voice spreads in a quiet place, which can damage others. Thus, in such a situation, the user 401 may want to answer the call with the whisper mode set automatically upon receiving the call.

Figure 6 (b) is a view showing that the call automatically in the whisper mode when receiving a call to the breathing (402). In this case, the whisper mode refers to a mode having a good setting for answering a call in a quiet space. Specifically, the whisper mode can amplify one's own voice and reduce the voice size of the other party. That is, it means a mode that amplifies the electric signal converted by the microphone and outputs it through the wireless communication unit, and attenuates the electric signal received through the wireless communication unit and outputs it to the sound output unit. If you make a call while the whisper mode is set, you do not have to worry about the other party's voice ringing in a quiet room. Could be.

As shown in FIG. 6, the user 401 may utilize breathing as a control input, and thus, the control of the mobile terminal 100 may be more convenient when the blowing is used.

FIG. 7 illustrates a method of improving call quality by using temperature and humidity sensed during a call using a mobile terminal. Referring to FIG. 7, the user 401 is making a call using the mobile terminal 100. FIG. 7 (a) illustrates a case where the distance between the mouth of the user 401 making a call and the mobile terminal 100 is d1, and FIG. 7 (b) illustrates that 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 using a mobile terminal may be performed at a club, a night, or a concert hall. In this case, it may be difficult for the other party of the call to accurately hear what the user 401 of the mobile terminal 100 says. In particular, when the distance between the mobile terminal 100 and the user 401 is far as shown in FIG. Difficult to do

In this case, as shown in FIG. 7B, the user 401 may take the microphone of the mobile terminal 100 toward his or her mouth. When the microphone of the mobile terminal 100 is brought to the mouth of the user, his / her voice may be clearly transmitted to the other party of the call.

Furthermore, as shown in FIG. 7B, when the user 401 takes the microphone toward his or her mouth, if the user's voice can be detected and amplified, the user's voice may be more clearly transmitted.

That is, when the temperature sensor and the humidity sensor are positioned near the microphone of the mobile terminal 100, the temperature and humidity detected when the user 401 brings the mouth toward the microphone may increase. Therefore, the controller 180 may detect that the user's mouth is close to the microphone if the detected humidity and temperature are equal to or greater than a predetermined value. If the user's mouth and microphone are close to each other, the controller 180 may amplify the voice of the user and transmit the amplified voice to the call counterpart.

In conclusion, when the user 401 tries to amplify his or her voice according to the situation in which the user is talking, the user 401 may place his mouth close to the microphone of the mobile terminal 100 and make a phone call. Therefore, according to one embodiment of the present invention, there is an advantage that the voice can be amplified only by positioning its mouth toward the microphone without any additional manipulation.

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.
