3 is a conceptual diagram showing a mobile terminal 200 according to an embodiment of the present invention. 3, the mobile terminal 200 may include a sensing unit 210, a position information module 220, a database 230, a display unit 240, and a controller 250.

The sensing unit 210 includes a living body signal sensing module 211 that senses a user's living body signal, for example, an ECG signal, a PPG signal, and the like, and external environment information, (Air pressure) information, temperature (temperature) information, humidity information, and the like.

The biological signal detection module 211 may include an ECG sensor 211a for sensing an ECG signal and a PPG sensor 211b for sensing a PPG signal. The ECG sensor 211a measures an activity current generated in a user's myocardium through at least two electrodes disposed on a main body of the mobile terminal 200 to sense an ECG signal. The PPG sensor 211b includes a light emitting portion (not shown) that generates incident light and irradiates the object (e.g., a part of the user's fingers, an ear or the like) and a light receiving portion (not shown) that receives reflected light reflected from the object And detects a PPG signal using reflected light for incident light. The light emitting portion may be implemented as a light emitting diode (LED), and the light receiving portion may be implemented as a photodiode (PD).

The environment information sensing module 212 may include a pressure sensor 212a, a temperature sensor 212b, and a humidity sensor 212c for sensing external pressure information, temperature information, and humidity information, respectively, as environmental information. However, the environmental information sensed by the environmental information sensing module 212 is not limited to the above, and may include various other information, for example, brightness information, noise information, and the like.

The sensing unit 210 may sense the bio-signal and the environment information in response to the change of the position of the mobile terminal 200. For example, when the mobile terminal 200 moves from the first area to the second area, the sensing unit 210 may sense biometric signals and environment information associated with the location information of the second area. This means that new bio-signals and environmental information are automatically collected every time the position of the mobile terminal 200 is changed.

The location information module 220 obtains location information of the mobile terminal 200. To this end, the location information module 220 may receive a Global Positioning System (GPS) signal or cell identification information (Cell ID). In an embodiment of the present invention, the location information may be obtained by user input.

The database 230 may be implemented as a memory 160 (see FIG. 1) and may store various data related to the healthcare function. For example, the database 230 may store a data table for settings related to the healthcare function and a data table for statistical management of the healthcare information associated with the location information.

The display unit 240 may display various screen images related to the healthcare function. For example, the display unit 240 may display an execution screen image of an application that manages the healthcare function. Also, the display unit 240 may be implemented as a touch screen that senses a touch input of a user.

The control unit 250 may execute an application for managing a healthcare function (hereinafter, referred to as a 'healthcare application') and may control an overall operation related to the healthcare function.

The controller 250 may generate the digitized biometric information using the biometric signal detected by the biometric signal detection module 211 when the health care application is executed. For example, the controller 250 analyzes the ECG signal and the PPG signal to generate digitized biometric information such as a user's heart rate, heart rate variability (HRV), blood oxygen saturation, and the like.

The control unit 250 can set a reference numerical range for comparing with the numerical value of the biometric information using the environmental information sensed by the environmental information sensing module 212. [ For example, the control unit 250 may set a reference numerical range for heart rate or blood oxygen saturation based on at least one of external pressure information, temperature information, and humidity information. At this time, the control unit 250 may refer to the data table stored in the database 230 (see FIG. 6A or FIG. 6B).

The control unit 250 compares the numerical value of the biometric information with the reference numerical value range and can generate warning information on the health state of the user according to whether the numerical value of the biometric information is included in the reference numerical value range.

The above-mentioned reference value range means a numerical range of a biological signal in which a user's health condition is judged to be safe in a certain environment. Therefore, when the numerical value of the biometric information is out of the reference numerical value range and the warning information is outputted, the user can recognize that his or her health may be dangerous in the environment.

The control unit 250 may control the database 230 to store the location information obtained by the location information module 220 or the user input in association with the biometric information, the environment information, and the warning information as described above. The controller 250 may generate the map information indicating the expected degree of danger for the health state of the user, by using the statistical data on the information stored in the database 230. Here, the statistical data may include an average value of each of the accumulated heart rate, blood oxygen saturation, pressure, temperature, humidity, and warning count in association with the same positional information. The generation and display of map information will be described in detail below with reference to Fig.

In the embodiment of the present invention, the degree of the expected danger level of the user by region (hereinafter, referred to as the 'expected danger level') is not limited to the map information but may be implemented in various forms. For example, the expected risk level can be implemented in the form of graphs, data tables, graphical icons, and so on.

4 is a flowchart illustrating a method of controlling the mobile terminal 200 according to an embodiment of the present invention. Referring to Fig. 4, first, a step S110 of executing a healthcare application is performed. A step S120 of sensing a user's bio-signal (e.g., an ECG signal, a PPG signal, etc.) at the time of execution of the health care application may be performed. Next, step (S130) of generating biometric information (e.g., heart rate, blood oxygen saturation, etc.) quantified using the bio-signal is performed.

In step S140, external environment information (e.g., pressure information, temperature information, humidity information, and the like) may be detected when the healthcare application is executed. Next, a reference value range for comparing the numerical values of the biometric information with the environment information is set (S150). This means that if the environmental information is different, the reference numerical range can also be varied and set.

Thereafter, the step of determining whether the numerical value of the biometric information is included in the reference numerical value range (S160) is performed. As a result of the determination, when the numerical value of the biometric information is out of the reference numerical value range, the step of generating and outputting warning information on the health state of the user is performed (S170).

As described above, according to the mobile terminal 200 of the present invention, in determining the health state of the user, the reference numerical value range of the biometric information is varied and set according to the surrounding environment information, Status reporting is possible.

5 is a flowchart illustrating a method of controlling the mobile terminal 200 according to another embodiment of the present invention. Referring to FIG. 5, a step S210 of acquiring location information of the mobile terminal 200 at the time of execution of the healthcare application is performed. Next, the step S220 of storing the position information, biometric information, environment information, and warning information in the database 230 (see FIG. 3) is performed.

Thereafter, step S230 of generating map information indicating the expected degree of danger by region using statistical data on the information stored in the database 230 is performed.

As described above, according to the mobile terminal 200 of the present invention, information related to the healthcare functions collected in various areas is accumulated in the database 230, and statistical information on the information stored in the database 230 is stored Using the data, map information is provided to indicate the degree of expected danger by region, so that the user can easily grasp the expected danger level before visiting a specific place.

6A and 6B are diagrams showing data tables stored in the database 230 according to an embodiment of the present invention. The data table of FIG. 6A provides a reference numerical range of heart rate corresponding to pressure information, temperature information, and humidity information. The data table of Figure 6B provides a reference numerical range of blood oxygen saturation corresponding to pressure information, temperature information, and humidity information. Therefore, the reference numerical range of the biometric information corresponding to the current environmental information can be set using this data table.

7 to 9 are conceptual diagrams showing a user interface of the mobile terminal 200 according to an embodiment of the present invention. Hereinafter, a description overlapping with the healthcare function described above will be omitted.

Referring to FIG. 7, when the numerical value of the biometric information is out of the reference numerical value range, the control unit 250 (see FIG. 3) displays warning information 241 on the health state of the user on the execution screen image of the healthcare application The display unit 240 can be controlled. The warning information 241 may include a warning phrase 241a, a warning level 241b, current ambient information 241c, and the like, as shown in the figure.

In addition, the control unit 250 can determine the warning level 241b based on the degree of the biometric signal being out of the reference value range. For example, the warning level when the value of the heart rate is deviated by 1 to 5 (times / minute) is determined as " low ", and the warning level when the value of the heart rate is deviated by 6 to 10 (times / Normal ", and the warning level when it deviates from 11 (times / minute) or more may be determined as " high ".

Also, the control unit 250 may control the display unit 240 to display the warning level 241b in the form of a graphic icon. For example, the alert level 241b may be implemented as a graphical icon, such as a traffic light, such that each level " high ", " normal ", and " low " correspond to " red, " . Accordingly, the user can intuitively recognize the degree of risk to his or her health condition.

Referring to FIG. 8, the controller 250 may control the display unit 240 to display detection history information 242 of the user's biometric information on the execution screen image of the healthcare application. The detection history information 242 can be implemented as a data table including time information at the time of generation of the biometric information, position information, pressure information, temperature information, humidity information, heart rate, blood oxygen saturation, have. Further, the detection history information 242 may be accumulated and managed in the database 230 every time biometric information is generated. Accordingly, the user can check the details of his / her health state in the past specific situation.

Referring to FIG. 9, the controller 250 may control the display unit 240 to display map information 243 indicating the expected degree of danger in the execution screen image of the health care application.

As described above, the map information 243 is generated based on statistical data on the information stored in the database 230. More specifically, the map information 243 includes a plurality of regions, and the degree of expected danger for each region is calculated in accordance with the accumulated heart rate, blood oxygen saturation, pressure, temperature, humidity, and warning May be determined based on at least one of the average values of the number of times.

In addition, graphical information representative of each step can be determined so that the steps of the expected risk level are distinguished from each other. For example, areas with "high" risk potentials and areas with "low" risk may be displayed with different colors, brightness, and so on.

In addition, in the map information 243, a region visited by the user at least once may be displayed separately from an area not visited by the user at least once. For example, an area where statistical data can not be detected, that is, an area that the user has never visited, may not show the expected risk level.

The control unit 250 can update the map information 243 when at least a part of the statistical data is changed. In more detail, when at least a part of the statistical data is changed due to the biometric information (biometric signal) newly collected at the time of changing the position of the mobile terminal 200, environment information, etc., Map information 243 reflecting the estimated risk level can be newly generated.
