Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100.

In accordance with the present invention, a position information module (115) is used to obtain the position (or current position) of a mobile terminal or a user based on a signal transmitted from a GPS satellite, It is possible to check the space where the current user is located by comparing the frequency characteristic of the sensed noise with the frequency characteristic of the noise of the space that is modeled and stored.

Further, the present invention detects noise inputted in real time through the microphone 122, compares the frequency characteristic of the sensed noise with the frequency characteristic of the noise of each space modeled and stored, The point at which the space changes, that is, the inflection point of space, can be determined. That is, the inflection point of the space can be grasped based on the inflection point of the noise. In this case, the occurrence of the noise distortion does not necessarily cause the space inflection point. For example, when a TV is used indoors, a noise inflection point is generated by the sound of the TV, but since the user is still staying indoors, a space inflection point is not generated. Accordingly, in the present invention, when a noise distortion occurs, the frequency characteristics of the noise are modeled and compared with the frequency characteristics of the noise of the stored space to judge whether or not the space is distorted. In the present invention, noise is used to mean surrounding noise and sound of peripheral devices. The spatial change identified by the noise inflection point can be output on the touch screen 151. [

Further, according to the present invention, it is possible to determine the space change due to the movement of the user based on the change of noise (or sound) input in real time through the microphone 122, output various UXs to the user, Corresponding to the selected UX, the application can be executed or the function of the mobile terminal can be executed. The execution screen of the thus executed application or function can be output on the touch screen 151. [

According to one embodiment, the movement of the user may include horizontal movement in the first space, vertical movement in the first space (e.g., elevator vertical movement), and horizontal movement from the first space to the second space. In addition, the first space may be an indoor space and the second space may include an outdoor space.

Also, the present invention discriminates at least one device (TV, refrigerator, audio, washing machine, etc.) constituting a home network system based on Internet of IOT (IOT) based on the noise inflection point at which noise is changed , Outputs the determined device to the touch screen 151, and controls the device. The control may be performed through gestures or voice. Accordingly, when a noise inflection point occurs in a device connected to an IoT-based home network system in a predetermined space, a user wearing the wearable device can temporarily control the device and control the device using a predetermined gesture.

Specific features of the present invention described below are that the location information module 115 is used to acquire the location (or current location) of the mobile terminal or the user based on the signal sent from the GPS satellite, (Space inflection point) with a noise change (noise inflection point) to provide a useful UX or to recognize a control target device with a noise change (noise inflection point) and perform a control operation Based on the concept.

FIG. 2 is a flowchart illustrating a method for providing information by recognizing occurrence of a space inflection point based on a noise change in a mobile terminal according to an embodiment of the present invention. FIG. 3 is an embodiment for detecting occurrence of a new event by analyzing user input.

The user can select the activation / deactivation of the function of detecting the occurrence of the space inflection point based on the noise inflection point and providing the related information according to the present invention. In another embodiment, such a function may be automatically set when a mobile terminal enters a shadow area or the intensity of a GPS signal is weak, or at a specific time zone (work time, appointment time, work time). In the present invention, the above function can be defined as a position tracking function based on a noise inflection point.

If the above function is set, the control unit 180 of the mobile terminal can analyze the input of the user (S100). These user inputs may include text, email and conversation content, respectively, in which case the analysis is done in the background. Through the analysis, the controller 180 can detect occurrence of a new schedule and recognize that a change in the space inflection point will occur due to the detected new schedule (S110). More specifically, as shown in FIG. 3, the controller 180 analyzes the contents of a call or a text message sent and received by the users, detects the occurrence of a new schedule, and extracts schedule information from the data included in the call content And stores it in the user schedule (S120).

The schedule information may include a time (e.g., 10 am tomorrow), a place (e.g., where it always meets) and a to-do (e.g., getting ready data) and an alarm time. Meanwhile, although not shown, as another example, the schedule information may include meetings, meetings, anniversaries, and the like. In particular, the control unit 180 can search for the existing conversation contents and the user history, and specify the appointment place ("always meeting place") as "Star cafe". In addition, the control unit 180 sets the alarm time to 9:00 am in consideration of the moving time (about 40 minutes) from the home to the appointed place (e.g., star cafe). The analysis result and the schedule information obtained by performing the steps S100 and S110 may be transmitted to a wearable device such as a smart watch through a short distance communication and shared.

If the analyzed result and the schedule information are shared through the steps S100 and S11, the control unit 180 of the mobile terminal or the smart watch activates the microphone 122 to detect the noise of the space where the current user is located in real time After the user is touched, the current space can be recognized based on the frequency characteristics of the drowned noise (S130). For this purpose, the user may preliminarily store the frequency characteristics of the noise in the space in the memory 170. For example, the space may include a building area, a bus, a car (city), a car (highway), an office, a street, a supermarket, a shopping mall, a train station, Can be increased.

The control unit 180 can determine whether a spatial change, that is, a spatial inflection point due to a noise change (noise inflection point occurrence), has occurred through comparison of the frequency characteristics of the noise as described above (S140). The control unit 180 may determine information to be displayed on the display unit 151 based on whether or not the identified space inflection point is generated. For example, if a space inflection point is not generated, it means that the user stays in the same space. Therefore, the flow advances to the previous step (S130) to analyze frequency characteristics of noise. If a space inflection point occurs, The controller 180 determines the information to be displayed based on the information and displays the information on the display unit 151 (S150). In this case, the controller 180 may provide the first information related to the schedule, provide the second information about the moved space, or provide the third information related to the previous space.

In addition, the controller 180 may analyze the behavior pattern of the user based on the repeated learning based on the big data, and may provide information corresponding to the analyzed behavior pattern. For example, if the user moves in and out of a certain space at a first speed while the user is riding in a parking lot, it can be inferred that the current user is looking for a parking space. It can be inferred that the current user is looking for the parked position and the corresponding information can be provided to the display unit 151. [

Meanwhile, the above-described operations can be performed both through the mobile terminal or the wearable device. For convenience of explanation, the present invention will be described by taking as an example a smart watch that the user can always carry.

FIG. 4 is a conceptual view for explaining an example of providing information when a space inflection point is generated due to a noise change according to an embodiment of the present invention, and FIGS. 5 and 5B are diagrams for explaining a method of providing information based on occurrence of a space inflection point This is a detailed embodiment showing the operation.

As described above, the controller 180 analyzes the user's call content, detects the occurrence of a new schedule and stores it in a schedule, recognizes that a change in the space inflection point will occur due to the new schedule, Function can be activated to start noise collection and frequency characteristic analysis at predetermined intervals. In addition, the controller 180 can analyze the behavior pattern of the user and predict the next behavior. For example, it can be deduced that the user is able to deduce that he or she is planning to go out when changing clothes or making make-ups, and to lower the speed if the user takes off the seatbelt. Based on the predicted behavior of the user, the controller 180 may adjust the noise collection and frequency characteristic analysis period to be shorter.

4, when the user leaves the house at a predetermined time, the control unit 180 of the smart watch worn by the user senses a noise change (occurrence of a noise inflection point) at the moment of opening the door, The frequency characteristics of the noise can be compared and it can be confirmed that the spatial inflection point is generated due to the noise change. Based on the occurrence of the space inflection point, the controller 180 can provide various information to the user. The various information may be provided in text or voice, and may be provided with vibration. In response to the type of the information, the user may input a touch or a voice to request confirmation of the provided information or provision of additional information.

On the other hand, as shown in FIG. 5A, when the user departs earlier than the alarm time set at 9:00 on the schedule (08:00), the control unit 180 of the smart watch changes the noise ), And compares the frequency characteristics of the noise collected from the house and the outside of the house to see if a space inflection point has occurred. When it is confirmed that the user has generated a space inflexion point due to the door knocking, the controller 180 can trigger the user to check the schedule of the user to check whether there is any unusual information.

The control unit 180 may recognize that there is a pre-stored schedule in the user schedule according to the confirmation result of the specific items, and may determine whether to output an alarm to the user based on the pre-stored schedule. As an example, the control unit 180 may display a schedule indicating "announcement of the task" at 10:00 and alarm at 09:00. In addition, the control unit 180 recognizes that the user departs earlier than scheduled on the basis of the schedule, and confirms whether there is an important matter related to the announcement of the task scheduled to be announced at the time of 10:00, and informs the user . The important items indicate that the prepared material should be taken as information about the prepared items extracted from the conversation contents before the preparation of the schedule. The information on the prepared items is stored at a predetermined time and place The information on the preparation may be displayed in text form on the display unit 151 together with the wrist vibration or may be displayed as a voice.

In addition to the above information, the control unit 180 checks the state of the house, more specifically, the state of the electronic apparatus in cooperation with the home network system based on IoT built in the house, and provides the state of the electronic apparatus to the user . For example, as shown in FIG. 5B, when the living room or the like among the electronic devices is turned on in the house, the control unit 180 can provide the user with the information and the sea-view plan. This information may also be displayed in text form on the display unit 151 together with the wrist vibration or may be displayed as a voice. In particular, the control unit 180 can display the house state information so as to be distinguished from the schedule information. The reason for this is that the state information of the house keeps the same state when the user is absent, which may lead to a situation unfavorable to the user such as electricity consumption or gas leakage. Furthermore, the control unit 180 may output the pieces of information so that the pieces of information can be distinguished from each other because the risk to the user is different for each state even if the information is the house state information.

In response to the user input to the solution, the controller 180 may transmit a control signal to turn off a control signal for controlling the operation of the at least one electronic device, for example, a living room, etc., in the IoT-based home network system .

FIG. 6 is a conceptual view for explaining another example of providing information when a space inflection point occurs due to a noise change according to an embodiment of the present invention, and FIG. 7 is a detailed view for providing information based on a space inflection point to be.

The space inflection point according to an embodiment of the present invention is determined by a change in noise, and may occur not only when a person goes outside a building in a building or outside a building, but also when a person leaves a car.

As described above, the control unit 180 can detect the occurrence of a new schedule by analyzing the conversation that the user gives and receives in real time. For example, in the case where the user desires to go to a nearby amusement park or park by car with his or her family on weekends, the control unit 180 adds the departure time and place (e.g., amusement park or park) to the schedule.

6, when the user family boarded the vehicle and departed to a destination (amusement park or park), the controller 180 provides the user with route guidance information based on the GPS information, and when approaching the destination, Activate the location tracking function based on the noise inflection point and make noise inside the vehicle. When the user arrives at the parking lot and completes the parking and then leaves the car, the control unit 180 detects a change in noise (occurrence of a noise inflection point) in the car and outside the car, compares the frequency characteristics of the noise collected in the car and outside the car, Has occurred. If it is confirmed that the space inflection point has been generated, the controller 180 triggers the space inflection point to use the GPS to place the current position (the last position where the door is opened) at the runner position P in the memory 170 . The stored parking position is also stored with a zone number (e.g., A-12) and surrounding photographs.

On the other hand, when a user spends time with a family member at a destination (an amusement park or a park) and then returns to his / her home, many cars are parked in almost the same form, so the user can not accurately ascertain where his / her car is parked. In this case, the user moves around from one side to the other side at a predetermined speed. In this case, the control unit 180 detects the speed, motion, and voice of the user through the sensor operated in the position tracking function based on the noise inflection point, analyzes the behavior of the user based on the sensed information, (P). If it is found through the series of operations that the user is looking for the parking position P, the controller 180 compares the current position of the user with the previously stored parking position P, And outputs the distance and direction to the parking position through the watch. The information on the parking position P may be displayed on the display unit 151 along with the wrist vibration in the form of text or may be displayed as a voice. If the parking position P is close to the parking position P, It is possible to output a larger value.

FIG. 8 and FIG. 9 are conceptual diagrams for explaining an example of providing information when a plurality of spatial inflection points are generated due to a noise change according to an embodiment of the present invention. Referring to FIG. 8 and FIG. 9, FIG.

In the present invention, the spatial inflection point according to the noise change (noise inflection point) can be generated at least once according to the user's transportation means. For example, as shown in FIG. 8, when a user goes to a department store with a vehicle, the controller 180 of the mobile terminal according to the present invention activates the microphone 122, And detects the occurrence of the space inflection point based on the noise change. When the controller 180 arrives at the underground parking lot of the department store, leaves the parking lot, gets off the parking lot, enters the department store, enters the elevator inside the department store, When you go out into the corridor, you can detect the occurrence of space inflection points one at a time. When going to an underground parking lot after shopping, a space inflection point occurs in the reverse order of the above.

The control unit 180 may trigger the generation of the spatial inflection point to provide the user with information based on the pre-stored information or the inferred user behavior at the corresponding location. For example, when getting out of the car, it is possible to notify the family that they have taken their belongings or to arrive at the department store, to store the parking position, to display the store information or the theater location when entering the department store, A shopping list to be purchased or a list of movies being screened and a reservation status related thereto can be displayed on the display unit 151.

On the other hand, if the user enters the underground parking lot of the department store through the elevator after shopping or watching the movie, the controller 180 may reverse the change of the inflection point due to the previously stored noise to recognize that the current user is going to the parking lot. Therefore, when the user enters the underground parking lot after getting off the elevator, the control unit 180 outputs the parking position P. Further, the information on the parking position P can be provided in more detail in conjunction with the server of the department store, and displayed on the display unit 151 together with the wrist vibration in the form of text or voice, (P), it is possible to change the color of the text or to output a larger voice. If the user moves in the wrong direction, the control unit 180 may provide the user with detailed information for guiding the user from the open position to the parking position.

FIG. 10 is another embodiment of detecting a new event by analyzing a user input. FIGS. 11 and 12 illustrate a case where a mobile terminal according to the present invention recognizes occurrence of a space inflection point based on a noise change and provides information related to a new event .

In the mobile terminal, the control unit 180 may analyze the input of the user. These user inputs may include text, email, and conversation content, respectively, and the analysis is done in the background. Through the analysis, the controller 180 can detect the occurrence of a new event and recognize that the spatial inflection point will change due to the detected new event. More specifically, as shown in FIG. 10, the controller 180 analyzes the contents of a call or a text message sent by the user, detects the occurrence of a new event, and extracts event information from data included in the call content Can be stored.

The event information may include time (e.g., at work), conversation partner (e.g., wife), tasks (e.g., going to fruit and buying anything). Meanwhile, although not shown, the control unit 180 may search the existing conversation contents and the user history to temporarily identify the time (at the time of leaving work) as "17:30" Through the analysis of the contents, it can be recognized that the user needs to go to the mart and buy the goods. In addition, the control unit 180 can set the alarm time to 17:20 PM. Such analysis result and event information can be shared between the mobile terminal and the smart watch through the short distance communication.

On the other hand, the control unit 180 of the mobile terminal or the smart watch can display the stored event information when the alarm time comes, activates the microphone 122 to receive the noise of the space where the current user is located in real time, To detect the occurrence of a space inflection point.

On the other hand, when the task is busy and the user does not have a space inflection point due to the noise change such that the general work time (17:30 minutes) passes, the controller 180 notifies the user . Specifically, the related notification may be a message asking whether or not to send a notification to the wife together with the statement that the person has failed to perform the task. If the related notification is text, the user responds with a touch input, and if it is voice, responds with a voice input. When the user inputs voice or touch in response to the related notification, the control unit 180 provides a list of notification contents to be sent to the wife in response to the user's input. The list of the notification contents is created based on the previously extracted event information. The list of the notification contents may also be output as text or voice.

In this way, the controller 180 transmits a text message containing the notification contents selected by the user to the wife from the list of notification contents, and subsequently checks whether a space inflection point due to the noise change occurs.

When the user finishes the work and then goes down to the parking window for the work at 20:30, the control unit 180 generates a space inflection point due to the noise change. As shown in FIG. 12, the controller 180 triggers the generated space inflection point and outputs an alert 50 corresponding to 'to-do' among the stored event information.

The user recognizes the contents 50 corresponding to the output 'to-do' and moves to the nearby large mart. During the mobility, the controller 180 guides the large mart frequently used by the user using the GPS information. When the user arrives at the large mart and enters the mart (vehicle -> outdoor -> indoor), the control unit 180 recognizes that a space inflection point based on the noise change has occurred and transmits the first recommendation information 51 ). The first recommendation information may include a question about whether to ask the wife about the purchase of the additional item. In response to the input of the first recommendation information 51, the control unit 180 transmits a text message to the user's 'wife', and the user purchases the article requested by the wife in addition to " And then board the vehicle.

Meanwhile, if a space inflection point due to a noise change occurs due to a user boarding the vehicle, the control unit 180 may provide the second recommendation information 52 to the user. The second recommendation information 52 may include the fact that the wife is now going home after finishing the service.

When the space inflection point due to the noise change is used as described above, the present invention can obtain relevant information through the change of the space when the time is not clear, such as after the work. In addition, when a user arrives at a designated position for a specific action (e.g., errand), he or she can prompt the participant (wife) to give a recommendation notice so that the user can perform additional actions. In other words, in most cases, it is difficult for a wife to ask the user for a desired job at the correct timing if there is an additional job (additional item purchase) because the user is currently in the mart or does not know whether she is moving. This is because sometimes the request for the desired work is made entirely by the wife's memories, so sometimes the user may request to purchase additional items after leaving the Mart. In addition, the present invention allows a wife to receive more accurate information from the position of a waiting wife because the user gives a notice related to the movement to the wife at the time of moving after viewing the work to be viewed at the mart.

In the above-described invention, the information providing method is described as an example of advancing from the first space to the second space using the space inflection point due to the noise change. However, the present invention is not limited to this, It is obvious that it is possible to provide information related to the first space or control the operation of the smart device located in the first space

The present invention proposes a method of creating a virtual map of the inside of a house using a mobile terminal and controlling the operation of a smart device in a specific space according to a user's location and movement route in the created virtual map. The smart device is a device connected to an IoT-based home network system.

FIG. 13 is a conceptual view for recognizing a user's position in a house using a virtual map of the inside of a house created using ultrasonic waves of a mobile terminal. FIG. 14 is a conceptual diagram for recognizing a space inflection point based on a user's location and a moving route in a house, And controls the operation of the device.

The user can generate a virtual map of the inside of the specific space by emitting ultrasonic waves to a specific space in the mobile terminal. For example, as shown in FIG. 13, when the user operates the ultrasonic generator while moving inside the room while wearing a smart watch, the controller 180 periodically generates ultrasound waves to create a virtual map of the inside of the house . At this time, when an unregistered space is generated, the controller 180 may ask the user for the name of the space. In particular, the name of the space makes it possible to select among the names of the spaces possessed by the home network system.

When the virtual map using the ultrasonic waves is completed, the controller 180 can find out where the user is by using the virtual map. That is, when the user moves from the first space to the second space in the house, the controller 180 compares the information generated by the ultrasonic waves at the current position with the information on the virtual map to grasp the current position and the movement path of the user .

When the home network system based on the IoT is operated based on the detected current position and movement route of the user, the mobile terminal according to the present invention can control the operation of the smart device. At this time, the smart device is controlled by a home network system based on IoT, and may be variously used such as a lighting device, a TV, a refrigerator, a washing machine, a boiler device, and other devices. For example, as shown in FIG. 14, when the user moves in the living room, the controller 180 confirms the location and movement path of the user using the ultrasound information at the current location and the previously created ultrasound virtual map. As a result, when the user enters the bedroom 1, which is the first space, into the living room, and a space inflection (point) occurs, the controller 180 turns on the smart lighting of the bedroom 1 to be moved. Thereafter, when the user moves from the bedroom 1, which is the second space, to the living room, which is the first space, and the space inflection (point) occurs again, the controller 180 turns off the smart lighting of the bedroom 1.

Meanwhile, in the mobile terminal according to the present invention, when the operation of the smart device is recognized by recognizing a space inflection point according to the movement of the user in the house, the operation of the smart device is finely controlled according to the speed of the user or the gesture input of the user . The speed of the user can be determined through an acceleration sensor included in the mobile terminal, and the control operation corresponding to the gesture is stored in the memory 170. [

FIGS. 15 and 16 show an embodiment in which the operation of the smart device is finely controlled based on the user's speed when the inflection point of space is generated by the movement of the user in the house.

As shown in FIG. 15, when the user wearing the smart watch moves through the living room and moves to the bedroom 1 after carefully picking up the front door, the controller 180 uses the ultrasound information at the current position and the previously prepared ultrasound virtual map The position and movement path of the user are confirmed, and the movement speed is measured using the acceleration sensor.

Accordingly, the controller 180 can control the intensity of the smart illumination differently based on the speed of the user. For example, when the measured speed is greater than the reference speed, that is, when the measured speed is higher than the reference speed, that is, when the measured speed is higher than or equal to the reference speed, When the room moves into the second space and a space inflection (dot) is generated, the smart lighting is turned to the normal intensity. On the other hand, when the measured speed is lower than the reference speed, that is, when moving slowly, the control unit 180 controls the illumination of the entrance hall, the kitchen and dining room, and the smart lighting of the bedroom 1, (About 10% of the maximum brightness). For example, if the user returns home late in the evening, the control unit 180 carefully turns on the smart lights of all the moving homes, such as sleeping, without brightening the smart lights.

Meanwhile, in the mobile terminal according to the present invention, when a user wearing a smart watch moves to a specific space, even if he / she does not perform any operation or command, he / Control is taken and the smart device can be adjusted with a simple gesture (or command). That is, when the user enters the bedroom 1 and a space inflection point is generated, the smart lighting is turned on as shown in FIGS. 14 to 16, but the additional control such as turning on or off the turned on smart lighting is performed according to the gesture or voice of the user .

The control method as described above uses a smart device (SmartWatch and SmartLight) as a connection trigger between an operation of entering a specific space in which a user is registered and an instruction to the smart device through a basic operation (gesture or voice command) It is a way to make it possible. More specifically, when the user enters a specific space where the user is registered, the control section of the smart watch automatically connects with the smart light to bring control to the smart light. Accordingly, as shown in FIG. 16, the smart watch can darken or turn off the smart light through the gesture of lowering the hand from top to bottom, and the smart light is emitted through the gesture of raising the hand from bottom to top Or brighten it.

Meanwhile, in the mobile terminal according to the present invention, it is possible to suggest a method of using a noise inflection point as a connection trigger between smart devices so as to be able to issue commands to the smart device through basic actions (gestures or voice commands). More specifically, when a noise inflection point is sensed, a device that is triggered by a noise inflection point and automatically generates a noise by connecting the device with a smart watch for a predetermined period of time and commands the smart device through a basic action (gesture or voice command) have.

17 is a conceptual diagram for automatically connecting smart devices triggered by noise inflection point generation.

The controller 180 can analyze noise frequency characteristics by collecting noise in a specific space through the microphone. For example, the control unit 180 stores the frequency characteristics of the noise collected when all the devices are off, sequentially collects the noise of various devices (TV, audio, mobile phone, alarm, etc.) The frequency characteristics can be stored. Based on the frequency characteristics of the stored noise, the controller 180 can detect occurrence of a noise inflection point in the same space. That is, in the previous embodiment, it is said that a noise inflection point occurs when a user moves to a second space that generates a different noise from the first space under the assumption that the same noise is generated in the same space. However, when noise is generated in the same space A noise inflection point is generated.

Accordingly, if a noise inflection point is detected in a specific space, the controller 180 automatically connects the device generating the noise with the smart watch for a predetermined time (about 5 seconds), and then generates the noise according to a gesture or a voice command of the user The operation of the device can be controlled. For example, as shown in FIG. 17, when a noise of a specific device (TV, audio, mobile phone) rings to generate a noise inflection point, the control unit 180 of the smart watch implicitly connects the smart watch with the specific device And recognizes the gesture (or voice) inputted by the user after the control of the specific device.

FIGS. 18 and 19 illustrate an embodiment in which noise is generated through a gesture using a noise inflection point as a connection trigger between smart devices.

For example, as shown in FIG. 18, when the user makes a TV (or audio) sound in the living room while the user is making food in the kitchen, May be requested to be smaller. However, in spite of the user's request, if the volume of the TV is not reduced, there is a problem that the user has to reduce the volume of the TV directly to the living room. As another example, as shown in Fig. 19, when an alarm sounds on the smartphone when the user is sleeping, the user has to wake up and stop the alarm directly.

In order to overcome such inconvenience, the controller 180 of the present invention analyzes frequency characteristics of noise generated in a specific space through a microphone to check whether a noise inflection point is generated. When an inflection point is generated, the smart watch is automatically connected to the corresponding device so that the user can recognize the gesture (or voice) and control the specific device.

Accordingly, in FIG. 18, when a son in the living room increases the volume of the TV, a noise inflection point is generated, and the smart watch is triggered by the noise inflection point and automatically connects with the TV so that the user in the kitchen can easily Can be adjusted. In addition, as shown in FIG. 19, when an alarm occurs in the smartphone when the user is sleeping and a noise inflection point is generated, the smart watch automatically connects with the smartphone. Therefore, the user moves the hand with the smart watch up and down (eg, sash) to turn off the smartphone alarm.

Since the control method using the inflection point of noise as described above has a high probability that the user desires to control the device which generates the noise distortion even if the user does not explicitly induce the connection, the smart watch is triggered at the detection of the inflection point of noise, By performing a connection for 5 seconds with the device that is occurring, the user controls the device according to the gesture or voice of the user without any manipulation of the connection.

As described above, according to the present invention, by detecting the occurrence of a space inflection point due to a noise change by analyzing the frequency characteristics of noise, it is possible to quickly and accurately detect a change in space caused by a user's movement.

Furthermore, according to the present invention, it is possible to provide information related to a schedule or an event on the basis of a point of time when a space inflection point occurs, or to provide parking information. In particular, It is possible to provide more accurate information to the user.

Further, the present invention analyzes the frequency characteristics of noise and automatically generates a noise inflection point according to the sound of a predetermined device, thereby automatically connecting the smart watch with the noise generating device. Thus, the user can perform a simple gesture or voice There is an effect that the device can be controlled.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
