The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. Vibration is a representative example of the haptic effect generated by the haptic module 154. The intensity and pattern of vibration generated by the haptic module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

In addition, the AR content may include various external environment information 330 such as climate information on the region where the terminal is located, that is, the location where the user exists. The AR content display screen 300 may display, as text 340, a disaster character received through the wireless communication unit 110 or situation information continuously received. In addition, according to a user input, various menus 350 for receiving an input signal for requesting a switch or exit from the emergency escape route information providing mode to another mode may be displayed.

4 is a flowchart illustrating an operation of providing a route guide in a mobile terminal according to another exemplary embodiment of the present disclosure. FIG. 5 is a diagram illustrating a screen displayed in a camera view mode when providing a route guide according to another exemplary embodiment.

In another embodiment of the present invention, a method for providing an emergency escape route in a situation in which it is impossible to obtain information on an area where a terminal is located will be described with reference to FIGS. 4 to 5.

4 to 5, when the message is received (step 402), the wireless communication unit 110 of the mobile terminal 100 parses the sender and the content of the received message (step 404). )

The controller 180 of the mobile terminal 100 parses the sender or contents of the received message and determines that the received message is a disaster notification message informing of a disaster situation. Run the escape application (step 406).

When the emergency escape application is executed, the location information module 115 of the wireless communication unit 110 is used to check the area where the mobile terminal 100 is located. In another embodiment of the present invention will be described with an example where it is impossible to check the local information where the mobile terminal 100 is located.

Therefore, if it is impossible to check the local information, the controller 180 determines whether emergency escape route information corresponding to a location corresponding to a location designated by the user is stored in the memory 160 (step 410).

The controller 180 determines whether the Wi-Fi communication is possible when the emergency escape route information of the location requested by the user does not exist in the memory 160, and when the communication is impossible, the controller 180 switches to the SOS mode to make an emergency to the outside. In operation 414, the mobile terminal enters the power saving mode to reduce the paging search time, thereby allowing the user to move the mobile terminal to the maximum extent possible in an emergency. You can make it available.

On the other hand, when the Wi-Fi communication is possible, the controller 180 may communicate with a nearby Wi-Fi transceiver through a Wi-Fi identifier to download information of the current location or emergency escape route information corresponding to the current location. The emergency escape route information may be information provided at a location or location including a transceiver capable of Wi-Fi communication. In addition to the Wi-Fi communication, it is possible to use a variety of wireless communication modules that can be provided with emergency escape route information.

The controller 180 can generate AR content by using the obtained emergency escape route information. The controller 180 can execute the camera view mode (step 418) and display the generated AR content (step 420).

FIG. 5 is an exemplary diagram of a case where user emergency escape route information obtained through the Wi-Fi communication is generated as an AR content and provided in a camera view mode.

In the AR content 500 including emergency escape route information displayed in the camera view mode, information (510), current location (511), arrow (512) The location of the shelter 513 may be displayed. In addition, emergency escape route information may be provided as text 520 when displaying AR content. In addition, according to a user input, various menus 530 may be displayed to receive a signal for requesting a switch or exit from the emergency escape route information providing mode to another mode.

In an embodiment of the present invention, for example, the emergency escape application may be executed according to a disaster text message received. However, the emergency escape application may be executed by a user request. In addition, it is possible to provide an escape route information in case of emergency on the movement route according to the current location and destination information by the user request rather than the disaster situation.

According to the embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
