In general, the mobile terminal 400 may include features of the mobile terminal 100 of FIG. 1 or similar features.

The frame portion is supported on the head portion, and a space for mounting various components is provided. As shown in the figure, electronic parts such as the control module 480, the sound output module 452, and the like may be mounted on the frame part. Further, a lens 403 covering at least one of the left eye and the right eye may be detachably mounted on the frame portion.

The control module 480 controls various electronic components included in the mobile terminal 400. The control module 480 can be understood as a configuration corresponding to the control unit 180 described above. This figure illustrates that the control module 480 is provided in the frame portion on one side of the head. However, the position of the control module 480 is not limited thereto.

The display unit 451 may be implemented as a head mounted display (HMD). The HMD type refers to a display method that is mounted on a head and displays an image directly in front of the user's eyes. When the user wears the glass-type mobile terminal 400, the display unit 451 may be arranged to correspond to at least one of the left and right eyes so that the user can directly provide an image in front of the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display unit 451 can project an image to the user's eyes using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

As described above, the image output through the display unit 451 may be overlapped with the general view. The mobile terminal 400 can provide an Augmented Reality (AR) in which a virtual image is superimposed on a real image or a background and displayed as a single image using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is configured to photograph a forward image. Since the camera 421 is positioned adjacent to the eyes, the camera 421 can acquire a scene viewed by the user as an image.

Although the camera 421 is provided in the control module 480 in this figure, it is not limited thereto. The camera 421 may be installed in the frame portion, or may be provided in a plurality of ways to obtain a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423a and 423b operated to receive control commands. The user input units 423a and 423b can be employed in any manner as long as the user operates in a tactile manner such as a touch or a push. This figure illustrates that the frame unit and the control module 480 are provided with user input units 423a and 423b of a push and touch input method, respectively.

In addition, the glass-type mobile terminal 400 may be provided with a microphone (not shown) for receiving sound and processing it as electrical voice data and an acoustic output module 452 for outputting sound. The sound output module 452 may be configured to transmit sound in a general sound output mode or a bone conduction mode. When the sound output module 452 is implemented in a bone conduction manner, when the user wears the mobile terminal 400, the sound output module 452 is brought into close contact with the head and vibrates the skull to transmit sound.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. 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.

3 is a flowchart illustrating a control method of the mobile terminal 400 according to an embodiment of the present invention.

First, the lens 403 can transmit light by the light transmittance according to the initial value (S310). Specifically, the controller 180 may adjust the light transmittance of the lens 403 according to a predetermined initial value.

Meanwhile, the control unit 180 may be formed on one side of the frames 401 and 402, as shown in FIG. Also, the frames 401 and 402 support and fix the lens 403, and are fixed to the head of the user so that the user can wear the mobile terminal 400. [

On the other hand, the lens 403 may change the light transmittance according to the change of the applied voltage. This may be referred to as a smart window or a smart glass. The amount of light or heat that passes through the lens 403 may be manually adjusted by the user, or may be adjusted automatically if predetermined conditions are met.

Accordingly, if the preset event does not occur (S320_N), the control unit 180 can control the lens 403 to transmit light according to the previous light transmittance.

On the other hand, if a preset event occurs (S320_Y), the controller 180 may control the lens 403 to adjust the light transmittance according to the generated event (S330). In this case, it is preferable that the controller 180 adjusts the light transmittance of the lens 403 so that the user can optimally view the external environment through the lens 403 according to the generated event. Also, the light transmittance adjusted according to the generated event can be stored in advance in the storage unit 170. Accordingly, the optimum light transmittance for the user can be provided to the user depending on each generated event. This will be described in detail with reference to FIGS. 4 to 10. FIG.

In addition, the user can manually adjust the light transmittance according to the adjustment device formed in the mobile terminal 400. [ Thus, the user can adjust the light transmittance to have a light transmittance that matches the current user intention.

This will be described in detail with reference to FIG. 11 to FIG.

FIG. 4 is an example of a diagram for adjusting the light transmittance according to the ambient illuminance in the mobile terminal 400 according to an exemplary embodiment of the present invention.

The sensing unit 140 may sense the illuminance around the mobile terminal 400. In this case, the sensing unit 140 may be formed at various positions of the mobile terminal 400, such as the frames 401 and 402 or the control module 480. Also, a plurality of sensing units 140 may be formed.

On the other hand, the controller 180 can adjust the light transmittance of the lens 403 in accordance with the sensed ambient illuminance. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 in accordance with the ambient illuminance value sensed by the sensing unit 140. FIG. In this case, the ambient illuminance value and the corresponding light transmittance may be stored in the storage unit 170 in advance.

As shown in FIG. 4 (a), the mobile terminal 400 may be located inside the tunnel. In this case, the ambient illuminance value sensed by the sensing unit 140 may be a low level. Therefore, the controller 180 can increase the light transmittance of the lens 403. [ Therefore, even if the user wears the glass-type mobile terminal 400, the user can observe the surrounding environment well.

Referring to FIG. 4 (b), the mobile terminal 400 may be located in a boundary region between the inside and the outside of the tunnel. In this case, the user's eyes are adapted to the illuminance inside the tunnel and need to gradually adapt to the illuminance outside the tunnel. Therefore, the controller 180 can reduce the light transmittance of the lens 403 as compared with the case of FIG. 4 (a).

Referring to FIG. 4 (c), the mobile terminal 400 may be located outside the tunnel and outside the tunnel. In this case, the illuminance value outside the tunnel may be higher than the illuminance value inside the tunnel. Therefore, the controller 180 can reduce the light transmittance of the lens 403 as compared with the case of FIG. 4 (b).

5 is a block diagram of an information transmitting / receiving system between a mobile terminal 400 and an external server 500 according to an embodiment of the present invention.

Referring to FIG. 5, the external server 500 may perform communication with the mobile terminal 400. That is, the information stored in the external server 500 can be transmitted to the mobile terminal 400.

Specifically, the external server 500 may store information on a specific area. In this case, the information may be weather information, risk information, event information, disaster information, etc. for a specific area. When the mobile terminal 400 requests information of a specific area through the communication unit to the external server 500, the external server 500 can transmit the requested information to the communication unit of the mobile terminal 400. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 in accordance with information received from the external server 500. [ In this case, the information on the specific region and the light transmittance corresponding thereto can be stored in the storage unit 170 in advance.

Meanwhile, the external server 500 can receive information on a specific area from a plurality of other terminals or other devices. Accordingly, the external server 500 can update information on a specific area in real time, and the mobile terminal 400 can receive updated updated information from the external server 500.

6 to 7, a description will be given of a configuration in which the light transmittance of the lens 403 is adjusted by communication between the mobile terminal 400 and the external server 500 according to an embodiment of the present invention and information according to such communication .

6 to 7 are various examples of light transmittance adjustment by information received from the external server 500 of the mobile terminal 400 according to an embodiment of the present invention.

4, when the sensing unit 140 senses the ambient illuminance of the mobile terminal 400, the controller 180 can adjust the light transmittance of the lens 403 in response to the sensed ambient illuminance, But is not limited to.

Specifically, the control unit 180 may transmit location information regarding the location of the mobile terminal 400 to the external server 500 through the communication unit. The external server 500 can transmit the weather information of the corresponding area to the communication unit based on the received location information. Therefore, when the communication unit receives the weather information, the control unit 180 can adjust the light transmittance of the lens 403 in accordance with the received weather information. In this case, the weather information and the light transmittance corresponding thereto can be stored in the storage unit 170 in advance.

For example, the weather condition of the area where the mobile terminal 400 is located may be clear. In this case, as shown in Fig. 6 (a), the control unit 180 can provide the optimal viewing condition to the user by reducing the light transmittance of the lens 403. [

In addition, the weather condition of the area where the mobile terminal 400 is located may be slightly cloudy. In this case, as shown in Fig. 6 (b), the controller 180 can increase the light transmittance of the lens 403 as compared with the case shown in Fig. 6 (a).

In addition, the weather condition of the area where the mobile terminal 400 is located may be rainfall. In this case, as shown in Fig. 6 (c), the controller 180 can increase the light transmittance of the lens 403 as compared with the case shown in Fig. 6 (b).

Meanwhile, the control unit 180 may transmit the location information about the location of the mobile terminal 400 to the external server 500 through the communication unit. The external server 500 can transmit the population information of the corresponding area to the communication unit based on the received location information.

Here, the population information may be information on the number of persons registered as the address of a certain range of the area where the mobile terminal 400 is located. In addition, the population information may be information on the number of people located in a certain range of the area where the mobile terminal 400 is located. Therefore, when the communication unit receives the population information, the control unit 180 can adjust the light transmittance of the lens 403 in accordance with the received population information. In this case, the population information and the light transmittance corresponding thereto can be stored in the storage unit 170 in advance.

For example, the number of the population of the mobile terminal 400 may be large. In this case, the controller 180 can increase the light transmittance of the lens 403 as shown in Fig. 7 (a). Therefore, by securing the view of the user as much as possible, safety can be secured from a complicated surrounding environment.

Also, the number of the population where the mobile terminal 400 is located may be a little larger. In this case, as shown in Fig. 7 (b), the controller 180 can reduce the light transmittance of the lens 403 as compared with the case shown in Fig. 7 (a).

Also, the population of the mobile terminal 400 may be small. In this case, as shown in Fig. 7 (c), the controller 180 can reduce the light transmittance of the lens 403 as compared with the case shown in Fig. 7 (b).

Meanwhile, the population information may not be received from the external server 500 but may be acquired by an image captured by the camera 421 attached to the mobile terminal 400. [ That is, the camera 421 can take an image of the surroundings of the mobile terminal 400. The control unit 180 can adjust the light transmittance of the lens 403 in accordance with the number of specific objects included in the photographed image.

For example, if the number of people included in the photographed image is more than a predetermined number, the control unit 180 can increase the light transmittance of the lens 403. [ The description thereof is the same as that described with reference to FIG. 7, and the details are omitted.

6 through 7, the communication unit can receive the danger information, the event information, the disaster information, and the like for the area where the mobile terminal 400 is located from the external server 500. [ In this case, the controller 180 can adjust the light transmittance of the lens 403 in accordance with the received various information.

For example, the control unit 180 may transmit location information on the location of the mobile terminal 400 to the external server 500 through the communication unit. In this case, the external server 500 can transmit danger information, event information, disaster information, and the like to the communication unit based on the received location information. Accordingly, when the communication unit receives the danger information, the event information, the disaster information, and the like, the control unit 180 can increase the light transmittance of the lens 403. [ In this case, the control unit 180 may display the received risk information, event information, disaster information, and the like in one area of the lens 403 as text, images, and the like. Therefore, by ensuring the maximum visibility of the user, safety can be secured from the risk of the surrounding environment and the like.

8 to 10 are various examples of drawings relating to light transmittance adjustment according to the sensing result of the mobile terminal 400 according to an embodiment of the present invention.

When the sensing unit 140 senses the user gesture, the controller 180 can adjust the light transmittance of the lens 403 corresponding to the sensed user gesture. In this case, the user gesture and the corresponding light transmittance may be stored in the storage unit 170 in advance.

Referring to FIG. 8, the user takes a gesture that raises the finger from the bottom up, and this user gesture can be sensed by the sensing unit 140. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 in response to the sensed user gesture.

In addition, a camera 421 formed on one side of the lens 403 or the frames 401 and 402 may photograph a user gesture. In this case, the camera 421 transmits an image of the photographed user gesture to the control unit 180, and the controller 180 can adjust the light transmittance of the lens 403 in accordance with the received user gesture. In this case, the image of the photographed user gesture may be a moving image.

Similarly, referring to FIG. 9, the user takes a fist-spreading gesture, and the light transmittance of the lens 403 can be adjusted by this user gesture.

Meanwhile, the sensing unit 140 may sense the speed of the user gesture, and the controller 180 may adjust the light transmittance of the lens 403 in response to the speed of the sensed user gesture. In this case, the speed of the user gesture and the corresponding light transmittance may be stored in advance in the storage unit 170. [

Referring to FIG. 8, the user takes a gesture slowly upwards or downwards, which raises his or her fingers, and the speed of the user gesture can be sensed by the sensing unit 140. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 corresponding to the speed of the sensed user gesture. In this case, the controller 180 may increase or decrease the light transmittance of the lens 403 in proportion or in inverse proportion to the speed of the user gesture.

In addition, the camera 421 may photograph the speed of the user gesture, and the description thereof is as described above.

Meanwhile, the sensing unit 140 may sense a user voice, and the controller 180 may adjust the light transmittance of the lens 403 in response to the sensed user voice. In this case, the user voice and the corresponding light transmittance may be stored in advance in the storage unit 170. [

Referring to FIG. 10, the user is referred to as 'darken', and such a user voice can be sensed by the sensing unit 140. Accordingly, the controller 180 can reduce the light transmittance of the lens 403 corresponding to the sensed user voice. Since the sensing unit 140 may sense the presence or absence of a user voice, if it is determined that the user's voice is not a registered voice even if the 'darken' sound is sensed, the control unit 180 may not perform the light transmittance adjustment have.

In addition, a microphone 122 formed on one side of the lens 403 or the frames 401 and 402 may input a user voice. In this case, the microphone 122 transmits the input user voice to the control unit 180, and the control unit 180 can adjust the light transmittance of the lens 403 in accordance with the received user voice.

11 to 12 are various examples of drawings relating to a user input mode of the mobile terminal 400 according to an embodiment of the present invention. The user input unit can be implemented in various forms, and FIGS. 11 and 12 illustrate the case where the touch pad 423b and the jog dial 423c (jog dial) are implemented, respectively.

When the user input unit inputs a user command, the controller 180 can adjust the light transmittance of the lens 403 in accordance with the inputted user command. In this case, the user command and the light transmittance corresponding thereto may be stored in the storage unit 170 in advance.

Referring to FIG. 11, a touch pad 423b is formed on one side of the control module 480, and the user touches and drags the touch pad 423b in one direction. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 in response to touch and drag in one direction on the touch pad 423b.

In this case, the controller 180 may increase or decrease the light transmittance of the lens 403 in proportion or in inverse proportion to the distance of the touch and drag on the touch pad 423b.

Referring to FIG. 12, a jog dial 423c is formed on one side of the frame 402, and the user can turn the jog dial 423c clockwise or counterclockwise. Accordingly, the controller 180 can adjust the light transmittance of the lens 403 in accordance with the rotation of the jog dial 423c in the clockwise or counterclockwise direction.

For example, if the jog dial 423c is rotated in the clockwise direction, the controller 180 can increase the light transmittance of the lens 403. Similarly, if the jog dial 423c is rotated in the counterclockwise direction, the controller 180 can reduce the light transmittance of the lens 403. [

Meanwhile, the controller 180 may increase or decrease the light transmittance of the lens 403 in proportion to or in inverse proportion to the rotational speed of the jog dial 423c.
