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 or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or in the vicinity of the touch screen.

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

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 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.

Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

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

Meanwhile, the controller 180 may perform different controls or may perform the same control according to the type of the touch object that touches the touch screen (or a touch key provided in addition to the touch screen).

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference between the time that the ultrasonic wave arrives using light as the reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, 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 detect a touch of a sensing target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the movement of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensor using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target can be obtained.

Various command signals or the power input from the cradle may be operated as signals for recognizing that the mobile terminal 100 is correctly mounted on the cradle.

The memory 170 may store a program for the operation of the controller 180 , and may temporarily store input/output data (eg, a phone book, a message, a still image, a moving image, etc.). The memory 170 may store data related to vibrations and sounds of various patterns output when a touch input on the touch screen is input.

The memory 170 is a flash memory type, a hard disk type, a solid state disk type (SSD), a silicon disk drive type (SDD), and a multimedia card micro type. ), card-type memory (such as SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read (EEPROM) -only memory), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk may include at least one type of storage medium. The mobile terminal 100 may be operated in relation to a web storage that performs a storage function of the memory 170 on the Internet.

Meanwhile, as described above, the controller 180 controls the operation related to the application program and the general operation of the mobile terminal 100 in general. For example, if the state of the mobile terminal satisfies a set condition, the controller 180 may execute or release a lock state that restricts input of a user's control command to applications.

In addition, the controller 180 performs control and processing related to voice call, data communication, video call, etc., or performs pattern recognition processing capable of recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively. can Furthermore, in order to implement various embodiments described below on the mobile terminal 100 according to the present invention, the controller 180 may control any one or a plurality of the components described above by combining them.

2 is a diagram for explaining short-range wireless communication of the mobile terminal 100 according to an embodiment of the present invention. Short-range wireless communication is Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity) , Wi-Fi Direct, and at least one of Wireless Universal Serial Bus (USB) technologies may be used to support short-distance communication.

In particular, Bluetooth is a representative short-range wireless technology standard for exchanging information by connecting mobile devices such as mobile phones, laptops, earphones and headphones. It is mainly used when a low-power wireless connection is required in an ultra-short distance of about 10 to 20 meters, and is used for wireless earphones, wireless mice, wireless keyboards, and smart watches 220 .

Bluetooth uses ISM (Industrial Scientific and Medical) frequency band of 2400~2483.5MHz, and among them, 2402~2480MHz except for 2MHz after 2400MHz and 3.5MHz before 2483.5MHz to prevent interference from other systems using upper and lower frequencies , for a total of 79 channels. ISM is a frequency band allocated for industrial, scientific, and medical purposes, and it is widely used in personal wireless devices that emit low-power radio waves because there is no need to obtain a license to use radio waves. Amateur radio, wireless LAN, and Bluetooth use this ISM band.

Since several systems use the same frequency band, there is a risk of radio wave interference between systems. To prevent this, Bluetooth uses a frequency hopping method. Frequency hopping is a technique of transmitting packets (data) little by little while moving a large number of channels quickly according to a specific pattern. Bluetooth hops the assigned 79 channels 1600 times per second.

Communication takes place only when this hopping pattern is synchronized between Bluetooth devices. Bluetooth is connected between devices in a master and slave configuration. If the slave device cannot be synchronized with the frequency hopping generated by the master device, communication between the two devices is not performed. As a result, it is possible to avoid interference from other systems and make a stable connection. For reference, multiple slave devices can be connected to one master device, and since the roles of the master and slave are not fixed, the roles can be switched depending on the situation.

The external device 200 connected through short-range wireless communication includes wearable devices 210 , 220 , 230 , 240 such as a headset 210 , a smart watch 220 , a smart band 230 , smart glasses, and smart shoes 240 . ), home appliances such as refrigerators, washing machines, air conditioners, and TVs, and vehicles such as automobiles and motorcycles can also be connected.

The mobile terminal 100 detects the strength of a signal transmitted and received with the external device 200 and measures the received signal strength indicator (RSSI) for each external device 200 to recognize the distance from the external device 200 . and a signal sensing unit. When the signal strength is greater than or equal to a predetermined level (above the signal strength reference), it can be connected to the mobile terminal 100 or controlled to execute a specific function.

3 is a view showing a screen for connecting a plurality of external devices 200 of the mobile terminal 100 according to this embodiment of the present invention. can The connected external device 200 is displayed (1511), and the signal strength of each external device 200 is displayed (1512).

An adjustment bar 1513 for adjusting the signal strength reference may be provided so that the user can set the signal strength for each external device 200 . Alternatively, the user may set 1514 whether the adjacent external device 200 is connected.

When a plurality of external devices 200 are connected to the mobile terminal 100 and are operated, a collision may occur with each other. In preparation for this, an operation related to the external device 200 having a high priority 1515 may be preferentially performed by assigning a priority 1515 to each external device 200 .

For example, when the wireless headset 210 and the wireless speaker are connected at the same time, if the priority 1515 of the wireless headset 210 is high, it is possible to control so that sound is output through the wireless headset 210 .

Hereinafter, when the mobile terminal 100 of the present invention is connected to the wearable devices 210 , 220 , 230 , and 240 by wireless communication, the control of the mobile terminal 100 will be described. In the case of the wearable devices 210 , 220 , 230 , and 240 , such as the wireless headset 210 and the smart watch 220 , the external device 200 may always be maintained in a state fixed to the user's body.

However, since the mobile terminal 100 must be held by hand, it may move away from the user's body in some cases. It is determined that the mobile terminal 100 is separated from the user according to the distance based on the strength of the wireless communication signal between the wearable devices 210 , 220 , 230 , and 240 and the mobile terminal 100 and controls the mobile terminal 100 . can

More specifically, if the mobile terminal 100 is located at a distance from the user and the user is located within a first distance in proximity, it is determined that the user intends to use the mobile terminal 100 and unlocks the mobile terminal 100 . can be (see FIG. 4).

The first distance may be set as a distance from each wearable device 210 , 220 , 230 , 240 when the user holds it by hand, and may be set differently depending on the type of the wearable device 210 , 220 , 230 , 240 . When the distance between the mobile terminal 100 and the smart watch 220 is less than 10 cm, the lock state of the mobile terminal 100 can be released, and in the case of the wireless headset 210, when the distance between the mobile terminal 100 and the smart watch 220 is less than 50 cm, the mobile terminal The lock state of (100) can be released.

When at least one of the plurality of wearable devices 210 , 220 , 230 , and 240 approaches within the first distance, the locked state of the mobile terminal 100 may be released. Alternatively, the lock state of the mobile terminal 100 may be unlocked only when the wearable devices 210 , 220 , 230 , and 240 with high priority are within the first distance.

FIG. 5 is a diagram illustrating the mobile terminal 100 when the wearable devices 210 , 220 , 230 , and 240 are located within a second distance greater than or equal to a first distance. It is necessary to restrict some functions rather than immediately entering the locked state when the first distance is out of the unlocked state. For example, you can pass it to a person next to you to enjoy a photo or video, and anyone other than the owner can use the photo-taking function.

That is, the mobile terminal 100 may not be completely switched to the locked state, but only some functions may be activated to limit functions other than the functions of the currently used application. More specifically, if the current camera application is being used, other applications may not be used or other photos may not be viewed in addition to the functions of photographing the camera and viewing the photographed photos.

When the running application provides one of a plurality of files such as documents, photos, and videos to the display unit 151, personal privacy can be protected by restricting the reading of files other than the corresponding documents, photos, and videos. If an editing function other than reading is provided, the editing and deletion functions may be restricted to prevent anyone other than the user from deleting and modifying it.

If it deviates more than the second distance as shown in FIG. 6 , it is determined that it is separated from the user by a certain distance or more, and the mobile terminal 100 is switched to the locked state again because the user is not using it. At this time, it is preferable to quickly release the locked state when approaching within the above-described first distance, but it is preferable to switch to the locked state when the locked state is switched to the locked state when the user moves outside the second distance for more than a predetermined time.

If the state of being separated by a third distance or more, which is greater than the second distance, continues for a predetermined time or longer, it may be determined that the mobile terminal 100 is lost. In other words, when a state separated by a third distance or more is maintained for several hours or several days, individual information can be protected by setting a double lock (refer to FIG. 7 ).

Also, in this case, the user can find the location of the mobile terminal 100 by transmitting the location information to the server or another terminal, and the mobile terminal 100 can be switched so that the user can remotely control it.

In addition, in case the user leaves the mobile terminal 100 at home and leaves the company, etc., when the third distance from the wearable device 210, 220, 230, 240 or more, the call is transferred and the call signal received by the terminal is transferred. You can control it to be delivered to your company's landline phone.

Alternatively, when the third distance or more, information stored in the memory of the mobile terminal 100 is transmitted to a server such as a cloud to prevent the problem of losing information even if it is lost.

Also, when the wearable devices 210 , 220 , 230 , and 240 are the headset 210 , a sound is output to the headset 210 while the headset 210 is connected to the mobile terminal 100 . However, since the corresponding function is performed through wireless communication, the user may forget that sound is output through the headset 210 when the user is not listening to music and is wearing it on his or her neck. That is, when an incoming call is received, the user may unconsciously try to make a call by holding the mobile terminal 100 to the side of his/her face.

In order to prevent this problem, as shown in FIG. 8 , when the headset 210 and the wireless terminal approach a fourth distance (for example, a distance of 10 cm or less), the sound output to the headset 210 is output to the headset. The wireless communication connection state with the 210 may be disconnected and a sound may be output through the receiver of the mobile terminal 100 .

9 is a diagram illustrating a control method according to the distance from the mobile terminal 100 to the external device 200 in an unlocked state according to an embodiment of the present invention, and FIG. 10 is a movement diagram according to an embodiment of the present invention. It is a view showing a control method according to the distance from the terminal 100 to the external device 200 in the locked state (S100). A method of controlling the mobile terminal 100 according to the distance between the aforementioned wearable devices 210 , 220 , 230 , and 240 and the mobile terminal 100 will be sequentially reviewed with reference to FIGS. 9 and 10 .

If the distance from the mobile terminal 100 to the wearable devices 210, 220, 230, 240 is less than the first distance in the locked state (S100), release the lock state of the mobile terminal 100 (S400) and move immediately The terminal 100 can be used.

However, in the case of being separated by more than a third distance (S300), it is determined that the mobile terminal 100 is lost and the mobile terminal 100 is switched to a double-locked state (S350), or location information is transmitted to a server or another terminal, or It is possible to remotely access and control the mobile terminal 100 . Alternatively, when a call signal is received, it is possible to control the call to be forwarded to another terminal.

When the headset 210 is located within a fourth distance from the mobile terminal 100 (S500), the mobile terminal 100 may block the connection with the headset 210 and control so that a sound is output through the receiver (S550). ). Corresponding control can be performed only when a call signal is transmitted and received.

The wearable devices 210 , 220 , 230 , and 240 other than the headset 210 may not need to determine whether or not they have entered within the fourth distance. Within the first distance (S600), it is determined that the user is in use and the unlocked state is maintained (S400).

When the wearable devices 210 , 220 , 230 , and 240 are located at a location spaced apart from the first distance, if within the second distance ( S700 ), functions may be restricted to allow only some functions to be used. As described above, only the camera application can be used, or only running photos, videos, and document files can be viewed. In addition, only functions executed by the owner may be used, and use of other functions may be restricted (S750).

If the wearable devices 210 , 220 , 230 , and 240 are separated from the mobile terminal 100 by a second distance or more, it is determined that the user is not using the mobile terminal 100 and can be switched to the locked state ( S100 ). .

11 and 12 are diagrams illustrating the mobile terminal 100 when the external device 200 is positioned within a fifth distance. An external device 200 other than the wearable devices 210 , 220 , 230 , and 240 may also be connected to the mobile terminal 100 through wireless communication. The external device 200 may be a home appliance 250 such as a refrigerator, a washing machine, an air conditioner, or a TV, or a vehicle 260 such as a car or a motorcycle.

In the case of home appliances, as shown in FIG. 11 , information is received from the external device 200 through the wireless communication unit 121 and the received information is output to the display unit, or the external device through the wireless communication unit 121 . (200) can be controlled.

If the external device 200 is the refrigerator 250, when the mobile terminal 100 approaches the refrigerator within a fifth distance, information such as the temperature of the refrigerator, the remaining amount of food inside, and the expiration date may be transmitted to the user. In addition, since the user can control the refrigerator through the mobile terminal 100 , a separate control button and an output screen for the refrigerator 250 may be omitted.

As shown in FIG. 12 , in the case of the car 260, at least one of adjusting the positions of the seat, rearview mirror, and side mirror of the vehicle and setting playback music may be controlled based on user information.

When several people use the car 260 at the same time, it is necessary to adjust the positions of the seat of the vehicle, the rearview mirror, and the side mirror according to the driver. However, when connected to the mobile terminal 100, the positions of the seat, rearview mirror and side mirror can be adjusted to the optimal driving state based on the driver's height, sitting height, leg length, arm length, etc. set in each mobile terminal 100. . Alternatively, it can be adjusted to the optimal seat, rearview mirror and side mirror positions stored in the terminal.

In addition, since different drivers may have different tastes in music, the genre of music played in the car 260 may be switched when information on music tastes is also included.

According to at least one embodiment of the present invention, the mobile terminal is automatically controlled through the distance from the external device 200 to minimize the inconvenience of having to operate it one by one, and it is possible to protect information by differentiating the degree of use right according to the distance. .

Even when lost, location information or remote control of the mobile terminal 100 is possible, which helps to find the mobile terminal 100 again.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
