More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The user may receive a command such as adjusting the sound volume and switching to the touch recognition mode of the display unit 251.

Meanwhile, as another example of the user input unit 223, a rear input unit (not shown) may be provided on the rear surface of the external terminal body. The rear input unit is manipulated to receive a command for controlling the operation of the external terminal 200, and the input content may be variously set. For example, commands such as power on / off, start, end, scroll, etc., volume control of the sound output from the first and second sound output units 252a and 252b, and the touch recognition mode of the display unit 251. Commands such as switching can be received. The rear input unit may be implemented in a form capable of input by touch input, push input, or a combination thereof.

For example, the rear input unit may be disposed at an upper end of the rear side of the external terminal body so that the user can easily manipulate the index by using the index finger when the user holds the external terminal body with one hand. However, the present invention is not necessarily limited thereto, and the position of the rear input unit may be changed.

As such, when the rear input unit is provided at the rear of the external terminal body, a new type user interface using the same may be implemented. In addition, when the touch screen or the rear input unit described above replaces at least some functions of the first operation unit 223a provided on the front of the external terminal body, the first operation unit 223a is not disposed on the front of the terminal body. The display unit 251 may be configured to have a larger screen.

On the other hand, the wearable device 100 according to an embodiment of the present invention described above can always detect the user's bio-signals as the main body is worn, and monitor the change in the user's bio-index corresponding to the detected bio-signals can do. In addition, when an event occurs during monitoring, the wearable device 100 generates a notification message informing the user of status information on the basis of the bio-index corresponding to the event, and transmits the generated notification message to the determined external terminal 200. Can be.

Accordingly, when the wearer of the wearable device 100 is in a stress situation, the user of the external terminal 200 may be automatically reported without the active action of the wearer. In particular, when a young child or an elderly person who is in need of periodic monitoring and management of a caregiver and who is unfamiliar with the operation of a terminal is in a stressful situation, the caregiver can quickly recognize the remote control and perform an action.

3 illustrates a representative operation implemented in a wearable device related to the present invention and a screen change of an external terminal according to such an operation.

Referring to FIG. 3, when the main body of the wearable device 100 is worn on a specific part (eg, wrist, ankle, head, etc.) of the body, the body signal of the user wearing the main body may be constantly detected. In the present invention, the wearable device 100 has been described as a watch type terminal by way of example, but is not limited thereto. The wearable device 100 may be extended to all types of wearable devices that may be worn on a user's body and may detect a biosignal.

As described above, while the wearable device 100 detects the user's biosignal, the display unit 151 may display a graphical user interface (GUI) corresponding to the detection of the biosignal. For example, as shown in FIG. 3, in the state in which time information is displayed on the front of the display unit 151, an icon 311 indicating that a function of detecting a biosignal is being executed is displayed on one area, and the other In the area, an image 312 showing a change in the bioindex corresponding to the biosignal may be displayed. In this case, the icon 311 and the image 312 may be displayed in a small size or have a predetermined transparency so that time information displayed on the display unit 151 is not hidden.

The wearable device 100 may calculate a biometric index of the user based on the detected biosignal and continuously monitor the change of the bioindex.

That is, when the wearable device 100 is worn, the biometric index of the user may be constantly measured based on electrical signals generated in the user's body through various sensors provided in the main body. In this case, in consideration of power consumption of the wearable device 100, the bioindex may be measured with low power consumption.

Here, the biosignal of the user may mean various electrical signals generated in the body of the user wearing the wearable device 100. The electrical signal may be, for example, any one of an ElectrocardioGram (ECG) signal, a Photoplethymogram (PPG) signal, or a Galvanic Skin Response (GSR) signal, but is not limited thereto. All kinds of signals widely used in the art may be included. For example, when the wearable device 100 further includes a body temperature sensor, a heart rate sensor, a pressure sensor, and the like, the biosignal detected therefrom may be further obtained.

When the biosignal is detected as described above, the wearable device 100 may calculate at least one bioindex based on the biosignal 100. Here, the bio-index is a conversion of the detected bio-signal into a numerical value representing the user's state, for example, indicating the user's emotional state such as stress index, drowsiness index, excitement index, pulse rate, blood pressure index, body temperature index, It includes all of the physical activity of the user, such as exercise index, activity index, and the like.

For example, the wearable device 100 may calculate a respiratory index, a stress index, or the like of the user based on the PPG signal detected through the sensor of the PPG provided in the main body.

While monitoring the change in the bio-index as described above, for example, when an event in which the bio-index increases than usual, the display unit 151 of the wearable device 100 corresponds to the increased bio-index as shown in FIG. The graphic object 321 indicating the user's status information, for example, a face image indicating the user's abnormal condition (eg, an excited state, a stressed state, etc.) may be displayed on the screen.

In this case, the event occurs when the bioindex increases outside the previously stored exponential pattern to satisfy the reference range or when the bioindex satisfying the reference range is reduced to follow the previously stored exponential pattern.

In this case, when determining the occurrence of the event, the controller 180 may exclude a case where the bioindex increases as the user's movement or activity increases. Alternatively, while the degree of movement of the user is detected to be greater than or equal to a predetermined value, the measurement of the biosignal may be stopped or the measured biosignal may be ignored. To this end, the controller 180 can detect the degree of movement of the user by activating the gyro sensor provided in the main body while detecting the biological signal.

Meanwhile, the exponential pattern for determining whether the bioindex is increased or decreased than usual may be set differently for each user who wears the wearable device 100. To this end, the wearable device 100 may store the personalized exponential pattern in advance based on the biosignal of the user measured for a predetermined period of time. In this case, the exponential pattern stored in the wearable device 100 is used as an index for determining the occurrence of an event while monitoring the change of the bioindex.

In addition, the reference range means a threshold value / critical range of the bioindex that is determined to be an abnormal state (for example, an excited state, a stress state, etc.) out of a previously stored exponential pattern.

The reference range may be set differently for each user like the exponential pattern. For example, a person who usually has a high stress index may have a higher stress index corresponding to the reference range than the average value, and a person who has a stress index below the average value may also set the stress index corresponding to the reference range lower than the average value. Can be.

When the event occurs as described above, a notification message indicating the status information of the user is generated based on the increased / decreased bioindex. The notification message generated as described above is automatically transmitted to a predetermined external terminal.

Here, a plurality of external terminals to which the notification message is transmitted may be set. In such a case, the notification message is transmitted to the plurality of external terminals at the same time, or the notification message according to a preset priority (for example, user preference) on the basis of whether or not the response is made. Can be transmitted.

Meanwhile, even while the notification message is transmitted, the output of the display related to the transmission of the message may be limited to the display unit 151 of the wearable device 100. That is, information previously output, for example, time information and execution information of a specific application, may be continuously output to the display unit 151, and the message may be transmitted in the background. Accordingly, the notification message being transmitted to the external terminal 200, for example, the parent terminal, may be performed without exposing the user or the third party to the wearable device 100.

In another embodiment, while the notification message is transmitted, as shown in FIG. 3, the display unit 151 of the wearable device 100 notifies that the notification message is being transmitted (for example, a letter envelope image). 331 may appear. In addition, when the notification message is transmitted, a predetermined vibration may be output from the main body or various tactile signals may be transmitted to a user who wears the wearable device 100.

In this case, when a touch input is applied to the image 331 or a touch input is applied to the display unit 151 in response to the vibration or tactile signal, a call connection can be attempted directly to an external terminal that is transmitting a notification message. have. Accordingly, a user wearing the wearable device 100 may directly call a user of the external terminal 200 without looking at the display unit 151 even in an emergency situation.

In addition, various conditions related to the transmission of the notification message may be imposed through the user setting when the notification message is transmitted. For example, the biometric index is collected more than usual, and the situation information at that time is collected, and the notification message is transmitted at a predetermined time unit (condition) or when the notification arrives at a predetermined place (condition) at once. Implementable

In addition, the controller 180 may detect sensors included in the wearable device 100 when the wearable device 100 is detached and is not worn within a predetermined time, that is, when the bio signal is not detected for a predetermined time after the occurrence of the event. By activating, information (eg, sound, video, location, etc.) about the surrounding situation may be collected and transmitted to the external terminal 200 in real time. In this case, the display unit 151 of the wearable device 100 may be displayed in an inactive state or an initial screen may be displayed so that a third party does not notice the transmission of the information.

In addition, the notification message transmitted is not only text but also an arrival alarm output in various forms that the user of the external terminal 200 can easily recognize through the five senses, for example, voice, sound, vibration, image, and video. Can be.

In addition, not only the status information of the user corresponding to the event, but also various situation information collected at the time of occurrence of the event may be attached to the notification message. For example, when an event occurs, the voice file, the captured image, the recorded image file, the current location information, etc. recorded by the wearable device 100 may be attached to the notification message and transmitted together with the external terminal 200.

When the notification message is transmitted as described above, a user interface (UI) for checking status information of the user wearing the wearable device 100 may be displayed on the display unit 251 of the external terminal 200.

For example, the display unit 251 of the external terminal 200 has an output area 341 indicating the state information of the user wearing the wearable device 100 and a function for checking the state of the user. Menu areas 343, 344, and 345 may be displayed together. In addition, a display area 342 for displaying a result of executing a specific menu selected based on inputs to the menu areas 343, 344, and 345 may be further displayed.

For example, as shown in FIG. 3, when a voice menu icon ('Voice') 344 is selected through a touch input, a voice recording file transmitted from the wearable device 100 may be executed. While the voice recording file is playing, a waveform image corresponding to the playing may be displayed on the display area 342.

Accordingly, when the wearer of the wearable device 100 is in a stress situation, the user of the external terminal 200 may be automatically notified of the situation without active operation of the wearer, and a quick confirmation of the specific situation is possible. .

4 shows a representative flowchart of operations implemented in the wearable device 100 according to the present invention.

Referring to FIG. 4, first, as the main body of the wearable device 100 is worn, a bio signal of a user may be detected at all times (S10).

Specifically, when the wearable device 100 detects that the main body is worn, the wearable device 100 activates various sensors provided in the main body, for example, a PPG sensor, a temperature sensor, a pressure sensor, and the like to measure a bio signal of the user. In this case, the biosignal of the user may be detected at all times. In this case, in order to minimize battery consumption of the wearable device 100, the biosignal may be detected in a low power mode, and the measurement period of the biosignal may be changed according to the current position and / or the size of the detected biosignal.

Based on the detected biosignal, the controller 180 of the wearable device 100 may monitor a change in the bioindex of the user wearing the main body (S20).

Here, as described above, the bioindex is a value converted from a detected biosignal into a numerical value representing a user's state. For example, the bioindex indicates a user's emotional state such as a stress index, drowsiness index, and excitement index, and a pulse rate and blood pressure index. , Body temperature index, exercise index, activity index, etc., including all that indicate the physical condition of the user.

In addition, the controller 180 may determine whether the calculated bioindex is lower / higher than or similar to the usual by comparing the calculated bioindex with a previously stored index pattern.

Here, the exponential pattern is an index for determining whether the calculated bioindex is increased or decreased than usual, and is different for each user who wears the wearable device 100.

To this end, the wearable device 100 may store the personalized exponential pattern in advance based on the biosignal of the user measured for a predetermined period of time. The exponential pattern stored in the wearable device 100 is used as an index for determining occurrence of an event while monitoring a change in the bioindex.

In addition, even the same user may have a different exponential pattern according to time, time zone, place, season, and other surrounding environments. When a plurality of corresponding exponential patterns are stored in the wearable device 100, the current time and / or location The exponential pattern suitable for the comparison can be selected and applied. In addition, it is also possible to modify and use the stored exponential pattern based on today's / current weather or the user's biorhythm.

Next, the controller 180 of the wearable device 100 may determine whether an event has occurred while monitoring the bioindex (S30).

Here, the event is, as described above, when the calculated bioindex increases out of the previously stored exponential pattern to satisfy the reference range, or decreases so that the increased bioindex that satisfies the reference range follows the previously stored exponential pattern. All cases may be included. The reference range means a threshold value or a threshold range of the bioindex determined as an abnormal state (eg, an excited state, a stress state, etc.) as the bioindex deviates from a previously stored exponential pattern.

As a result of the determination, when the event occurs, the controller 180 generates a notification message informing the user of status information based on the bioindex corresponding to the event, and transmits the generated notification message to a predetermined external terminal (S40).

In this case, the notification message may include various contextual information, such as voice information and video information, in addition to text information informing user state information corresponding to an event occurrence. Here, the status information includes log information that records the operation of the wearable device 100 and external information (eg, ambient sound, video, etc.) input to the wearable device 100.

To this end, the controller 180, if an event occurs, means and functions for collecting various situation information, for example, a microphone, a camera, a voice recording function, a camera automatic shutter function, STT function, image recording function At least one of the may be activated. In this case, an indication indicating the activated means and functions may be displayed on the display unit 151.

In addition, the collection range of the situation information may vary according to the state of the user corresponding to the event occurrence. In detail, the controller 180 may change a range of means and functions to be activated and a collection range of contextual information according to the extent to which the bioindex deviates from a previously stored exponential pattern. For example, if the user's bioindex, for example, the stress index is high, more specific contextual information needs to be collected, thereby activating more means and functions, and thus the extent of collection of contextual information (eg, Voice, ambient noise, location information, ambient video, etc.)

As such, when the situation information is collected according to the execution of the means and functions included in the wearable device 100, the controller 180 may convert the information into a file form and attach it to the notification message.

In addition, the controller 180 may set a type of an application to which the notification message is to be transmitted through a user input. Specifically, the notification message is transmitted using an application frequently used by a user of the external terminal 200 or the notification message is transmitted in a form in which the user of the external terminal 200 can check the notification message using a familiar user interface. Can be.

According to an embodiment of the present invention described above, when an abnormal state is found based on a biosignal of a user (eg, a child) wearing the wearable device 100, an external terminal (eg By automatically transmitting to the parent terminal, the parent having an external terminal can immediately and accurately check the safety of the child wearing the wearable device 100.

Hereinafter, referring to FIGS. 5, 6A, 6B, 6C, 7, 7, 8, 9A, and 9B, when an event occurs while monitoring a bioindex of a user wearing the wearable device 100. In the following, the various operations involved are described in more detail.

First, FIG. 5 shows an example of a method of generating a notification message when an event occurs.

As shown in FIG. 5, the display unit 151 of the wearable device 100 monitors a bioindex (eg, heart rate index, body temperature index, etc.) measured based on a detected biosignal (eg, a PPG signal). A graphic object 501 indicating the result may be displayed, for example, histograms indicating the current body temperature index and the heart rate index.

The bioindex measured as described above may be monitored based on a user's usual index pattern stored in advance in the wearable device 100. Thus, as shown in FIG. 5, the biometric index corresponding to the user's usual exponential pattern may be displayed in a dotted line on the display unit 151.

During the monitoring of the bioindex, when the bioindex is increased beyond the previously stored exponential pattern, the controller 180 may change the measurement period of the bioindex to be shorter to more accurately identify the abnormal state of the user. On the other hand, if the bioindex is monitored within a pre-stored exponential pattern for more than a predetermined time (for example, 10 minutes or more), in consideration of battery consumption of the wearable device 100, the measurement period of the bioindex can be changed to longer than before. have.

As described above, when monitoring a bioindex, as shown in FIG. 5, when a specific bioindex (eg, body temperature index) increases to detect an event that deviates from a previously stored exponential pattern (baseline), the controller 180 displays the location information of the main body. The voice recording function may be activated by activating the microphone 122 provided in the main body.

Thereafter, the controller 180 generates a voice file by recording a voice of the user for a predetermined time. In this case, while the user's voice is being recorded, an image 502 indicating that the voice recording function is being executed is shown on the display unit 151 while the user's voice is being recorded, but the sound information is being collected to the third party. In order not to do so, no information may be displayed on the display unit 151.

The voice file generated as described above is attached to a notification message informing the user's status and transmitted to a predetermined external terminal (eg, a parent's terminal). In this case, the display unit 151 may display a graphic object (eg, a clip image) indicating that there is a file attached to the notification message being transmitted.

Meanwhile, in another example, when an event occurs in which the measured bioindex deviates from a previously stored exponential pattern, the camera may be activated in the wearable device 100 to execute an auto shutter function or to perform an image recording function without a recording signal. Can be. In addition, the captured image or video may be attached to the notification message.

In addition, the controller 180 may maintain the aforementioned voice recording function / self-timer function / video recording function even after the notification message is transmitted, and may continuously transmit the execution result of the function to the external terminal through streaming. Accordingly, the user of the external terminal 200 can continuously monitor the user's state and surrounding conditions of the user wearing the wearable device 100.

Meanwhile, when the wearable device 100 is detached while the bioindex of the user wearing the wearable device 100 exceeds or exceeds a previously stored exponential pattern after the event occurs, the external terminal 200 is detached. Along with the emergency message indicating the emergency state, as a notch for this, it can output an alarm signal in the form of sound, vibration, voice and the like. The wearable device 100 may be automatically switched to a lock mode so that information about the surrounding situation may be continuously collected and transmitted. Thus, by blocking the operation of the sensors equipped with the wearable device 100 from being turned off by an external input, information can be continuously collected and transmitted.

In addition, although not shown, in one embodiment, the control unit 180 may determine the occurrence of the next event by reflecting the confirmation result of the notification message from the external terminal after the transmission of the notification message.

For example, when a response to a notification message (eg, message reception, call connection, etc.) is received from an external terminal, the biometric index decreases later than when the notification message is generated, but the state in which the biometric index has been reduced to follow the previously stored exponential pattern is If not, the controller 180 may process that an event has not occurred. On the other hand, if there is no response to the notification message within the reference time, it can be treated as an event occurred again in the case where the bioindex is decreased later than the generation of the notification message, but not yet reduced to follow the stored exponential pattern. have.

In addition, depending on the type of response to the notification message (e.g., only when the message is confirmed, or when a call is connected), increase or decrease the criterion (prestored exponential pattern) for treating the event as occurring or change the measurement interval of the bioindex. can do. On the other hand, when a response to the notification message is not received from the external terminal, the controller 180 may determine that an event has occurred in the same situation thereafter, and thus transmit a second notification message to the external terminal.

In the above description, when an abnormality is detected in a biosignal of a user wearing the wearable device 100, embodiments of informing the situation through a notification message to a specific person have been described. On the other hand, in some cases, active verification and action by a specific person may be necessary, especially when a user wearing the wearable device 100 is an immature child or an elderly man.

Therefore, hereinafter, examples of controlling an operation of the wearable device through an external terminal after generation of an event will be described in detail with reference to FIGS. 6A, 6B, and 6C.

As described above, the controller 180 of the wearable device 100 may increase the bioindex measured based on the biosignal to deviate from the previously stored exponential pattern to satisfy the reference range, or increase to satisfy the reference range. When the biometric index is reduced to follow the pre-stored exponential pattern, it is reported that an event has occurred and a notification message is transmitted to an external terminal.

On the other hand, the monitoring result of the bio-index, when the degree of deviation of the measured bio-index from the pre-stored exponential pattern (changing pattern of the user's usual bio-index) exceeds the reference range, that is, the state is determined to be an emergency, the control unit 180 attempts to connect a call to a predetermined external terminal 200. Here, the reference range refers to a threshold value or a threshold range of the bioindex that is determined as an abnormal state (for example, an excited state, a stress state, etc.) beyond the previously stored exponential pattern.

As a result of monitoring the change in the biological index as described above, even in a state determined to be an emergency, the display unit 151 displays an indication of such a state, or actions according to the determination as an emergency (eg, a call connection attempt). May not be displayed. Accordingly, the state of the user and the operation of the device according to the third party can be made without being exposed to the third party.

As another example, as shown in FIG. 6A, when the stress index of the user wearing the wearable device 100 is determined to be an emergency, information indicating the user's state or an indication related to the operation of the device is displayed on the display unit 151. May be output to

In detail, the face image 601 indicating the emergency situation may be displayed on the display unit 151 together with the text information (eg, 'Stress Extremely high'). In this case, the expression of the face image 601 may change according to an increase in the stress index.

Next, the controller 180 may automatically try to connect to a predetermined external terminal, that is, 'Mom' among stored contact information.

Meanwhile, although FIG. 6A illustrates that an image 602 indicating that 'Auto calling' is being connected to the display unit 151 is output, such an image 602 is output so that the call connection is not exposed to a third party. It may not be as described above. At this time, if the stress index of the user wearing the wearable device 100 is determined to be an emergency situation before the above-described notification message is transmitted, the transmission of the notification message may be omitted and a call connection may be immediately made to a predetermined external terminal. have.

When the terminal of the 'Mom' responds to a call, the call may be performed in the 'Listening Mode' as shown in FIG. 6A so that the user wearing the wearable device 100 may check the situation. Accordingly, the voice uttered by 'Mom' may not be output from the wearable device 100, and only a voice, an ambient sound, and an image of a user wearing the wearable device 100 may be transmitted to the external terminal 200.

In this case, an image 603 indicating that the call is in a 'Listening Mode' may be output to the display unit 251 of the external terminal 200 connected to a call, or an image photographed and transmitted by the wearable device 100 may be output. Subsequently, when a predetermined time elapses or an operation (eg, a touch input to the image 603) is applied to the terminal of 'Mom', the 'Listening Mode' may be released and converted to a normal video call / voice call.

In addition, when the call is connected in this way, the controller 180 may execute a control mode in which the operation of the main body is controlled through an operation on an external terminal (hereinafter, may be referred to as a 'remote control mode').

In this case, the display unit 151 of the wearable device 100 may limit the display indicating that the remote control mode is being executed and the output of the screen change according to the remote control. As such, it can be performed without exposing the remote control mode to the third party. In this case, the screen change according to the remote control may be displayed only on the display unit 251 of the external terminal 200.

As another example, while the remote control mode is executed, the indicator 611 indicating that the remote control mode is running may be displayed on the display unit 151 of the wearable device 100 as shown in FIG. 6B.

When the remote control mode is executed, the controller 180 can provide menu information for controlling the operation of the wearable device 100 to the external terminal 200. The provided menu information may be displayed on the call screen of the external terminal 200.

For example, in the display unit 251 of the external terminal 200 illustrated in FIG. 6B, the first area 605 may include an image transmitted from a call counterpart, and an image of itself owned by the front camera 251. 613 and an indicator 612 indicating a call mode ('Listening Mode') may be displayed. In addition, in the second area 620 of the display unit 251, various menu icons 621, 622, and 623 for controlling the wearable device 100, for example, a voice recording function icon, a camera shooting icon, and a memo. Icons and the like can be displayed. When a proximity touch is detected on any one of the icons 621, 622, and 623, guide information indicating a function of the icon (eg, 'the camera is activated in John's mobile phone') may be popped up.

A user of the external terminal 200 may search for and select a desired menu icon by applying a drag touch input to the second area 620 in a left / right direction.

For example, when the touch input is applied to the second area 620 to the left, a location search icon 624 is touched among the new icons 624 and 625 outputted to notify the current location of the wearable device 100. You can control the function to run.

When the desired menu icon is selected as described above, the screen change corresponding to the input applied to the menu icon is output on the call screen of the wearable device 100.

Accordingly, the display unit 251 of the external terminal 200 notifies the map screen 606 corresponding to the current location notification function executed in the wearable device 100 and the current location of the wearable device 100. The object 614 may be displayed the same. In this case, the call screen previously output on the display unit 251 may disappear or only an image transmitted from the call counterpart may be output in a small size.

On the other hand, in the embodiment in which the screen change according to the operation of the display unit 251 of the external terminal 200 is equally applied to the display unit 151 of the wearable device 100, the map screen 606 is applied to the map screen 606. When the zoom-out touch input is applied, the map screen 606 is enlarged based on the touch point of the touch input, and the same screen change is applied to the display unit 151 of the wearable device 100, that is, John's mobile phone. Is output.

As another example, when the voice recording function icon 621 is selected on the call screen of the external terminal 200 as shown in FIG. 6C, the voice recording function is executed in John's mobile phone, and the video call can be switched to 'Listening Mode'. have. In addition, the menu icons 621, 622, and 623 that are output in the second area 620 of the external terminal 200 are switched to submenus related to the voice recording function, for example, a volume control bar 631. Can be.

As the touch input is applied to the volume control bar 631, the volume of the voice recording function may be remotely controlled in John's mobile phone. In one example, the graphic object 641 similar to the volume adjustment bar 631 may be displayed on the wearable device 100 while the volume is adjusted.

In addition, the controller 180 may collect situation information by automatically activating at least one sensor provided in the main body even in a state in which a remote control mode is executed and the operation is controlled according to an operation on the external terminal 200. have. Then, based on the operation after the call connection or in the remote control mode, the collected situation information may be transmitted to the external terminal 200 by streaming together with the previously recorded information.

As described above, in the present invention, the remote control of the wearable device 100 may be automatically performed so that a specific person (eg, a parent or a family) specifically checks the situation of the user of the wearable device 100. In addition, the wearable device 100 may actively collect and provide information so that a specific person may quickly check the situation.

Also, although not shown, when the remote control mode is executed as shown in FIGS. 6B and 6C, and a response (eg, speech utterance or menu icon selection) is not received from the external terminal 200 for a reference time. The controller 180 may transmit a notification signal (eg, a beep sound, a guide voice prompt, a vibration, etc.) for inducing a response to the external terminal at predetermined time intervals.

Meanwhile, in the aforementioned call call connection and / or remote control mode, after the notification message is transmitted according to the occurrence of the event, the biometric index corresponding to the event is for a reference time (eg, 5 minutes or until the next bioindex measurement). It can be executed even if it persists. Here, the reference time may be set or changed through a user input.

That is, when the state of the user of the wearable device 100 is not an emergency state but the abnormal state persists, the call call connection and / or the remote control mode is automatically executed to allow the user of the external terminal 200 to confirm. Can be.

In this case, when the call is connected to the external terminal 200, the controller 180 may transmit the location information of the wearable device 100 to the external terminal 200 in real time. In this case, a notification signal for inducing a user of the external terminal 200 to check the transmitted location information may be transmitted at a predetermined time interval.

Such a remote control mode may be terminated when the connected call is terminated or when an input for releasing the remote control mode is applied from the external terminal 200. Meanwhile, the controller 180 may control the remote control mode to be maintained without being terminated even when there is an operation in the wearable device 100 while the remote control mode is executed. This is to prevent the remote control mode from being released due to an unintentional action of the user of the wearable device 100 that is immature with the operation of the terminal.

As another embodiment, FIG. 7 illustrates an example of a next operation of the wearable device when a call connection with an external terminal fails.

When the abnormal state of the user determined based on the bio-index measured by the wearable device 100 lasts a predetermined time or the degree of deviation from the pre-stored index pattern exceeds the reference range, as shown in FIG. 7, A call call connection is attempted to a specific person (eg, 'Mom') terminal (701). At this time, an attempt to connect a call may be repeated a specific number (eg, three times).

On the other hand, if the call connection with the 'Mom' is unsuccessful, the controller 180 transmits a notification message (eg, 'I think a problem occurred. Please contact') to the external terminal that failed to connect the call (702). Thereafter, the controller 180 automatically attempts to connect a call to another preset external terminal (eg, 'Daddy') (703). To this end, in the memory 170 of the wearable device 100, contact information of a plurality of people who will be connected to a call in an abnormal state of the user may be stored with a priority.

Meanwhile, the controller 180 continuously monitors a change in the bio index of the user while attempting to connect a call to a specific person. As a result, for example, when the stress index further increases, as shown in FIG. 7, the image of the notification icon 711 indicating the stress state is changed on the display unit 151 of the wearable device 100. It can be displayed (711 ”). Here, changing and displaying the image means applying the size, color, transparency, and highlighting effect of the notification icon 711 differently than before.

In contrast, an event occurred even when the stress index exceeded the reference range (801) and thus attempted to connect a call to a specific person (802), while the stress index of the user was reduced to follow a pre-stored exponential pattern. As shown in FIG. 8, the call call connection may be automatically terminated before the external terminal 200 answers.

As shown in FIG. 8, a face image 803 indicating that the emotional state of the user is improved is output to the display unit 151 of the wearable device 100. In addition, the external terminal 200 may be sent a notification message informing the user of the improved state.

Meanwhile, as another embodiment, FIGS. 9A and 9B illustrate examples of a notification method that varies depending on the degree of change of the bioindex when an external terminal is in a call at the time of event occurrence.

In detail, the controller 180 of the wearable device 100 may determine a notification method of the notification message, for example, an arrival time point, a guidance method, and the like according to a degree in which a user's bioindex corresponding to an event deviates from a previously stored exponential pattern. You can do it differently.

For example, as a result of monitoring the bioindex, when the degree of deviation from the previously stored exponential pattern is within a threshold or threshold range of the bioindex determined as a reference range, that is, an abnormal state, the user's state is not an emergency situation, and thus, FIG. 9A. As described above, the mobile terminal waits until the call 902 of the external terminal 200 ends (903) and informs the arrival of the notification message 904. At this time, the notification message 904 does not actually arrive after the end of the call, but means that the voice, screen display, vibration, etc. indicating that the arrival is output after the end of the call.

In addition, for example, when the result of the monitoring of the bio-index, if the degree out of the previously stored exponential pattern exceeds the reference range, that is, it is determined that the emergency situation, as shown in Figure 9b even during a call of the external terminal 200 It can inform the arrival of a notification message. In this case, the user of the external terminal 200 can recognize the arrival notification of the notification message even during a call, for example, to notify the arrival of the notification message through sound or vibration.

In detail, the controller 180 may notify the arrival of the notification message in the form of a voice message or a voice guide that guides the arrival of the notification message during a call of the external terminal 200. As such, while the arrival notification of the notification message is output, the call voice may be automatically muted (902b).

In addition, the controller 180 externally displays a specific image (eg, an image photographed by the wearable device 100) so that the screen information 904 for inducing an emergency situation is displayed on the call screen of the external terminal 200. It may be transmitted to the terminal 200. Accordingly, the previously displayed call screen 902 is displayed in the minimum size (902a), and the screen information 904 is switched to the screen to be output on the front of the display unit 251. In this way, the voice guide and the call screen for guiding the arrival of the notification message may be simultaneously or sequentially made.

In addition, the controller 180 may transmit a predetermined alarm signal (eg, a voice message or an image) for quick confirmation at the external terminal 200 while the bioindex is out of a previously stored exponential pattern exceeding a reference range. Etc.) can be transmitted at predetermined time intervals.

On the other hand, it has been described above as an example the external terminal is busy, but is not limited thereto. For example, it may be similarly applied when another application (eg, video play, music play, etc.) is running in the external terminal, or when the external terminal is powered off.

As described above, in the present invention, by providing a notification in a form that the user of the external terminal 200 can be confirmed faster according to the degree of emergency of the situation of the user of the wearable device 100, it contributes to ensuring the safety of the user do.

According to another embodiment, the controller 180 of the wearable device 100 may collect log information related to a monitoring result of a change in the bioindex and provide it to an external terminal at a predetermined cycle. Accordingly, the user of the external terminal 200 may periodically report the biometric index and abnormal state of the user wearing the wearable device 100, and receive the information that can be checked through the wearable device 100. Can be.

10A to 10C are exemplary conceptual views for explaining a method of checking and managing a bioindex monitoring result in an external terminal according to an embodiment of the present invention.

The controller 180 of the wearable device 100 may monitor the biometric index of the user every predetermined period (eg, 1 day) and log information (eg, a specific application or function) that records the operation of the main body. Activation of, to provide to the external terminal (200). In addition, the external terminal 200 may receive the information, classify it by time, place, and the like, and in particular, generate and manage an integrated history based on the time point at which the event occurs.

As an example of the integrated history, as shown in FIG. 10A, a graph 1001 of various bioindices (eg, stress index, heart rate index, activity index, body temperature index, etc.) monitored for one day in the wearable device 100 is an event occurrence time point. The display unit 251 of the external terminal 200 may be displayed together with the operations 1010, 1012, and 1013.

When a touch input is applied to a specific event occurrence time 1010, a screen 1002 for checking situation information collected at the event time, for example, audio information and location information 1014 and 1015, is displayed.

As another example of the integrated history, histograms indicating a change in a specific bioindex (eg, stress index) for each time zone may be displayed on the display unit 251 of the external terminal 200 as shown in FIG. 10B (1021, 1022, and 1023). , 1024). In this case, when a touch input is applied to the specific time zone region 1021, a screen 1031 displaying situation information corresponding to a change value of another bioindex in the corresponding time zone region is displayed.

As another example of the integrated history, as shown in FIG. 10C, the rhythm of the comprehensive bioindex for the day may be displayed on the display unit 251 of the screen 1041 of the external terminal 200. The screen 1041 may include a region displaying a change in a comprehensive bioindex in a day, a region showing position information of the wearable device 100 at the time an event occurs, and a region showing a comprehensive score of each bioindex. Can be. When a drag touch input is applied to the screen 1041 from side to side, the screen 1051 is switched to a screen 1051 in which the rhythm of the comprehensive bioindex of the previous / next day is confirmed.

On the other hand, if the user of the external terminal 200 has additional information (eg, call history, message history, etc.) before and after the event that the user wants to record more when the event occurs in the wearable device 100, the above-described integrated history Can be stored together.

In addition, in the embodiments described with reference to FIGS. 6A to 9B, an image indicating a user's state displayed on the display unit 151 of the wearable device 100, an image corresponding to transmission of a notification message and a call connection, and an external connection A part or all of an icon indicating a screen change corresponding to a remote control by the terminal 200 and a sensor activated for information collection may be omitted. That is, the above-described operations are executed in the background of the device 100 and output to the display unit 151 so that a third party does not know that information is collected about an emergency situation or that such a situation is being reported to a specific person. May be limited.

As described above, according to the embodiments of the present invention, when a child or an elderly person who wears the troubled device is in a stressed state, the guardian may naturally report it without active action of the wearer. In addition, in order to recognize the situation more accurately and leave a record, it is possible to automatically make a call to the guardian and remotely control it without a user's operation.
