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, an infrared proximity sensor, and the like. 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 furthermore, provides visual information corresponding to the processed data. It can be printed on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor receives a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. detect

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, capacitance at the time of touch, and the like where a touch object applying a touch on the touch screen is touched on the touch sensor. 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, a stylus pen, or a pointer.

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). Whether to perform different controls or the same control according to the type of the touch object may be determined according to the current operating state of the mobile terminal 100 or a running application program.

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 based on 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 at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated by using a time difference from the time that the ultrasonic wave arrives using light as a 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 motion 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 diode. 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.

The display unit 151 displays (outputs) information processed by the mobile terminal 100 . For example, the display unit 151 may display information on an execution screen of an application program driven in the mobile terminal 100, or user interface (UI) and graphic user interface (GUI) information according to the information on the execution screen. .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

A three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glassesless method), or a projection method (holographic method) may be applied to the stereoscopic display unit.

The sound output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. The sound output unit 152 also outputs a sound signal related to a function (eg, a call signal reception sound, a message reception sound, etc.) performed in the mobile terminal 100 . The sound output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that the user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration.

Meanwhile, various embodiments below may be implemented in a computer-readable recording medium using, for example, software, hardware, or a combination thereof.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different air interfaces and/or physical layers. For example, air interfaces available by communication systems include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA). ), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), etc. this may be included.

Hereinafter, for convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including CDMA wireless communication systems as well as OFDM (Orthogonal Frequency Division Multiplexing) wireless communication systems.

The CDMA wireless communication system includes at least one terminal 100, at least one base station (Base Station, BS (also referred to as Node B or Evolved Node B)), and at least one base station controller (Base Station Controllers, BSCs). ), and a mobile switching center (MSC). The MSC is configured to be connected to a Public Switched Telephone Network (PSTN) and BSCs. BSCs may be connected in pairs with a BS through a backhaul line. The backhaul line may be provided according to at least one of E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, and xDSL. Accordingly, multiple BSCs may be included in a CDMA wireless communication system.

Each of the plurality of BSs may include at least one sector, and each sector may include an omni-directional antenna or an antenna pointing in a specific radial direction from the BS. In addition, each sector may include two or more antennas of various types. Each BS may be configured to support multiple frequency assignments, and each of the multiple frequency assignments may have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency allocation may be referred to as a CDMA channel. BSs may be referred to as Base Station Transceiver Subsystems (BTSs). In this case, one BSC and at least one BS may be collectively referred to as a “base station”. A base station may also refer to a “cell site”. Alternatively, each of a plurality of sectors for a specific BS may be referred to as a plurality of cell sites.

A broadcast transmitter (BT) transmits a broadcast signal to the terminals 100 operating in the system. The broadcast reception module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by BT.

In addition, a global positioning system (GPS) for confirming the location of the mobile terminal 100 may be linked to the CDMA wireless communication system. The satellite helps to locate the mobile terminal 100 . Useful location information may be obtained by two or fewer or more satellites. Here, the location of the mobile terminal 100 may be tracked using not only the GPS tracking technology but also all techniques capable of tracking the location. In addition, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 provided in the mobile terminal is for detecting, calculating, or identifying the location of the mobile terminal, and representative examples include a Global Position System (GPS) module and a Wireless Fidelity (WiFi) module. If necessary, the location information module 115 may perform any function of the other modules of the wireless communication unit 110 to obtain data on the location of the mobile terminal as a substitute or additionally.

The GPS module 115 calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude. can do. Currently, a method of calculating position and time information using three satellites and correcting errors in the calculated position and time information using another one satellite is widely used. In addition, the GPS module 115 may calculate the speed information by continuously calculating the current location in real time. However, it is difficult to accurately measure the position of the mobile terminal using the GPS module in the shaded area of the satellite signal, such as indoors. Accordingly, in order to compensate for positioning using the GPS method, a WiFi Positioning System (WPS) may be utilized.

A Wi-Fi positioning system (WPS: WiFi Positioning System) uses a WiFi module provided in the mobile terminal 100 and a wireless AP (Wireless Access Point) that transmits or receives a wireless signal with the WiFi module, the mobile terminal 100 As a technology for tracking the location of a wireless network, it refers to a wireless local area network (WLAN)-based positioning technology using WiFi.

The Wi-Fi location tracking system may include a Wi-Fi positioning server, the mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which arbitrary wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP may transmit a location information request message to the Wi-Fi location location server.

The Wi-Fi positioning server extracts information on the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100 . Information on the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi positioning server through the mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi positioning server.

Based on the location information request message of the mobile terminal 100, the extracted wireless AP information is MAC Address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), RSRQ ( Reference Signal Received Quality), channel information, Privacy, Network Type, signal strength, and noise strength may be at least one.

As described above, the Wi-Fi positioning server may receive information on a wireless AP connected to the mobile terminal 100 and extract wireless AP information corresponding to a wireless AP to which the mobile terminal is connected from a pre-established database. At this time, the information of arbitrary wireless APs stored in the database includes MAC Address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of the wireless AP, the name of the building where the wireless AP is located, the number of floors, and detailed indoor location information (GPS coordinates). available), the AP owner's address, phone number, and the like. In this case, in order to remove a mobile AP or a wireless AP provided using an illegal MAC address in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in order of increasing RSSI.

Thereafter, the Wi-Fi positioning server may extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. By comparing the included information and the received wireless AP information, the location information of the mobile terminal 100 is extracted (or analyzed).

As a method for extracting (or analyzing) the location information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, a landmark method, etc. may be utilized.

The Cell-ID method is a method of determining the location of a wireless AP having the strongest signal strength among nearby wireless AP information collected by the mobile terminal as the location of the mobile terminal. It has the advantages of being simple to implement, not requiring additional cost, and being able to obtain location information quickly, but has a disadvantage in that positioning accuracy is lowered if the installed density of the wireless AP is low.

The fingerprint method is a method of collecting signal strength information by selecting a reference position in a service area, and estimating the position through signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to database the propagation characteristics in advance.

The triangulation method is a method of calculating the position of a mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminal. In order to measure the distance between the mobile terminal and the wireless AP, the signal strength is converted into distance information, the time at which a wireless signal is transmitted (Time of Arrival, ToA), and the time difference of the signal is transmitted (Time Difference of Arrival, TDoA) , the angle at which the signal is transmitted (Angle of Arrival, AoA), etc. may be used.

The landmark method is a method of measuring the location of a mobile terminal using a landmark transmitter that knows the location.

In addition to the enumerated methods, various algorithms may be utilized as a method for extracting (or analyzing) location information of a mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi positioning server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may acquire location information by being connected to at least one wireless AP. In this case, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

Next, an operating method of a mobile terminal according to an embodiment of the present invention will be described with reference to FIGS. 2 to 17 .

The mobile terminal according to an embodiment of the present invention learns a function used by a user, and intends to recommend customized content according to the user's preference or the user's level of use of the function.

2 is a block diagram illustrating a content recommendation system according to an embodiment of the present invention.

As shown in FIG. 2 , the content recommendation system may include a mobile terminal 100 and a server 200 .

The mobile terminal 100 may be the same as described with reference to FIG. 1 . The mobile terminal 100 may transmit/receive data to and from the server 200 through the wireless communication unit 110 . According to an embodiment, the server 200 may transmit at least one content to the mobile terminal 100 ( 200 ).

The wireless communication unit 110 of the mobile terminal 100 may receive at least one content from the server 200 . The display unit 151 of the mobile terminal 100 may display at least one content received from the server 200 .

When receiving a plurality of contents from the server 200 , the controller 180 of the mobile terminal 100 may display a content list indicating the plurality of contents.

Here, the content may include content information for describing a function included in the mobile terminal 100 . For example, the content may include a content title indicating a function included in the mobile terminal 100 and a content description indicating a method of using the function. However, this is only an example, and the content may include content information for describing various types of information.

3 is an exemplary diagram illustrating a method in which a conventional mobile terminal displays content received from a server.

The server 200 may transmit a plurality of contents to the mobile terminal 100 every predetermined period. In this case, the server 200 may transmit the same content to all the mobile terminals 100 . For example, the server 200 may select specific content, such as popular content, recent content, or content inquired to a service center for a predetermined period, and transmit it to the mobile terminal 100 at once. Alternatively, the server 200 may select content for each model of the mobile terminal 100 and collectively transmit the content to the mobile terminal 100 that matches the model.

The mobile terminal 100 may receive a plurality of content from the server 200 and display it on the display unit 151 . As shown in (a) of FIG. 3 , the display unit 151 may display a content list 30 indicating a plurality of contents. The content list 30 may include a plurality of content items 31 to 35, and each item may include a title indicating each of the plurality of contents.

The controller 180 of the mobile terminal 100 may receive a command for selecting any one content item included in the content list 30, and the display unit 151 displays a content content screen ( 40) can be displayed. The content screen 40 may include a content title 41 and a content description 42 . Referring to FIGS. 3A and 3B , the controller 180 receives a command to select the first content item 31 from the content list 30, and the first content item 31 A content content screen 40 including a content title 41 and a content description 42 corresponding to may be displayed.

Conventionally, since the server 200 transmits content in a batch, all the mobile terminals 100 had no choice but to display the same content list. Therefore, it is difficult to reflect the interest of the user, the user's preference, the user's function use level, etc., so there is a limit in meeting the user's needs, and there is a problem in that the function utilization is low.

4 is a flowchart illustrating a method for a mobile terminal to receive and display user-customized content from a server according to an embodiment of the present invention.

Referring to FIG. 4 , the controller 180 may receive a control command ( S11 ).

Here, the control command may include all kinds of commands for operating the mobile terminal 100 . The control command may include a command for executing various functions provided in the mobile terminal 100 . For example, the control command includes various commands for controlling the mobile terminal 100, such as a text transmission command, a font change command, a Bluetooth setting command, a Wi-Fi setting command, a home screen setting command, a lock screen setting command, or a storage space confirmation command. can include all of them. In addition, the control command may include a command to select and read a specific content from a content recommendation list to be described later.

The controller 180 may detect a user action based on the control command (S13).

The controller 180 may analyze the received control command to determine the user's preferred function, the user's function level, and the like.

5 is an exemplary view for explaining a control command received by a mobile terminal according to an embodiment of the present invention.

According to an embodiment, the input unit 120 of the mobile terminal 100 may receive a command to turn on the camera 121 , and the display unit 151 may display the camera function screen 50 .

The camera function screen 50 shows the environment setting icon (51a), the mode setting icon (51b), the filter setting icon (51c), the screen change icon (51d), the flash setting icon (51e), the auto mode icon (51f), the general It may include a camera icon 51g, a wide-angle camera icon 51h, a rewind icon 51j, a shooting icon 51k, a video icon 51l, an album icon 51i, and the like. The input unit 120 may receive a command for selecting any one of the plurality of function icons 51a to 51l included in the camera function screen 50 .

In this case, the control command may include both a command for turning on the camera 121 and a command for selecting any one of the plurality of function icons 51a to 51l.

For example, the controller 180 may receive a command to turn on the camera 121 , a command to select a wide-angle camera icon 51h , and a command to select a photographing icon 51k . Accordingly, the control unit 180 may determine that the user's preferred function is the 'wide-angle camera function' and the user's function use level is the 'camera function-wide-angle camera function'.

There may be various methods for the controller 180 to detect a user action based on the received control command.

According to an embodiment, whenever a control command is received, the controller 180 may detect a user action by counting the score of a category and a score of a function corresponding to each control command.

6 is an exemplary diagram illustrating category classification of content according to an embodiment of the present invention, and FIG. 7 is an exemplary diagram illustrating functional classification of content according to an embodiment of the present invention.

Each content belongs to one category and may belong to one function.

According to an embodiment, each function of the mobile terminal 100 may be classified among similar functions to correspond to one category. The category may be plural, and may include an upper category and a lower category. A parent category may include a sub-category, and a sub-category may include another sub-category. Categories can be added or modified. When the upper category is the same, it may indicate that the function is similar.

Referring to FIG. 6 , the upper category 61 may include communication, screen, network, general, multimedia, and the like, and the lower category 62 is phone, message, home screen, second screen, multi-window, mobile data, and peripheral devices. , battery, charge, replacement, lifespan, consumption, settings, internal, internal storage, memory, app, calendar, camera, photo shoot, selfie, square, normal mode, video expert, gallery, video, album, audio, etc. can

The types of categories shown in FIG. 6 and the upper/lower relationships of categories are merely exemplary and do not need to be limited thereto.

Meanwhile, the mobile terminal 100 may include various functions, and each function may belong to at least one category. In addition, the function may include an upper function and a lower function belonging to the upper function.

Referring to the example shown in FIG. 7 , the mobile terminal 100 includes a setting function 71 , a mode setting function 71 , a filter function 71 , a screen change function 71 , a flash function 71 , and a focus function. (71), a wide-angle function (71), a photo taking function (71), a video recording function (71), an album function (71), a location recognition function (71), and the like, and the functions listed above are photo taking It may belong to category 62 .

The controller 180 may detect a user action by counting the category score and the function score to which the received control command belongs. For example, the controller 180 counts the score of the camera category 62 upon reception of a command to turn on the camera 121 , and receives a command to select the wide-angle camera icon 51h of the wide-angle function 71 . The score may be counted, and the score of the picture taking function 71 may be counted upon reception of a command to select the shooting icon 51k. The controller 180 may detect a user action by analyzing the score counted in this way.

The controller 180 counts a category score or a function score based on at least one of a type of control command, the number of times each control command is received, and a content item selected from a content recommendation list to be described later, and based on the counted score to detect user actions.

However, this is only an example, and the controller 180 may detect a user action by receiving a user's control command in various ways. Meanwhile, FIG. 5 illustrates a control command using a camera function as an example for convenience of description, and there is no need to be limited thereto.

Again, FIG. 4 will be described.

The controller 180 may determine whether a command for displaying a content recommendation list has been received (S15).

When not receiving a command for displaying a content recommendation list, the controller 180 may continuously receive a control command and detect a user action.

On the other hand, when receiving a command for displaying a content recommendation list, the controller 180 may receive a plurality of contents from the server 200 based on a user action (S17).

Specifically, when receiving a command for displaying a content recommendation list, the controller 180 may transmit data related to a user action to the server 200 . The server 200 may select a predetermined number of contents based on data related to user actions and transmit them to the mobile terminal 100 . The wireless communication unit 110 of the mobile terminal 100 may receive a plurality of contents from the server 200 .

The controller 180 may display a content list indicating a plurality of received contents (S19).

8 is an exemplary diagram illustrating a method for a controller to display a content list indicating a plurality of contents according to an embodiment of the present invention.

The controller 180 may display the content list screen 10 in response to receiving a command to display the content recommendation list.

The content list screen 10 may include a content search window 20 and a content list 30 . The content list 30 may include a plurality of content items 31 to 35 indicating each of a plurality of content received from the server 200 .

As described in the example of FIG. 5 , when the controller 180 determines that the user's preferred function is 'wide-angle camera function', content including the camera category 61 or content including the wide-angle function 61 can be received. . Accordingly, referring to the example of FIG. 8 , the controller 180 controls a content item 31 with a content title of 'Wide-angle camera', a content item 32 with a content title 'How do you select an angle?' A content item (33) with a content title 'How do I switch between shooting modes using a wide-angle camera?', a content item (34) with a content title 'What is a dual camera?' Is it better to use the wide-angle mode when taking pictures?', a content item 35 may be displayed.

In this case, the number of content items included in the content list 30 and the titles of the content items are merely examples for convenience of description, and thus need not be limited thereto.

Again, FIG. 4 will be described.

In this way, the controller 180 may display the content list by analyzing at least one or more received control commands. Accordingly, the mobile terminal 100 may display content related to the user's preferred function or display appropriate content to the user in consideration of the user's level of use of the function.

Meanwhile, the controller 180 may determine whether a command for selecting the first content item from the content list has been received (S21).

That is, the controller 180 may receive a command for selecting any one of a plurality of content items included in the content list.

Meanwhile, a specific content item among the plurality of content items may be selected within a predetermined time, but the specific content item may not be selected even after a predetermined time elapses. In addition, when a specific content item is selected, the content is output, and a function corresponding to the output content may or may not be executed in the mobile terminal 100 .

In this way, if a specific content is continuously displayed even if it is not selected for a predetermined time or more, or if a specific content is already selected and continues to be displayed even though the user has checked the corresponding content, the user feels somewhat uncomfortable or rather not provided with the necessary content. There may be problems you can't.

Accordingly, the mobile terminal 100 according to an embodiment of the present invention detects whether a specific content is selected, whether a function included in the specific content is executed, and the like to delete the displayed content or to re-recommend previously displayed content. can

9 is a time flow diagram illustrating a method for a mobile terminal to set a content display period and a content display time according to an embodiment of the present invention.

The controller 180 may display a content recommendation list including a plurality of content items.

The controller 180 may count the time displayed for each content item.

If any one of the plurality of content items is not selected for a reference period of time, the controller 180 may regard the content as not of interest to the user and set the content not to be displayed for the first period.

On the other hand, when the control unit 180 receives a selection command of the first content item, which is any one of the plurality of content items, within the reference time, the first content description corresponding to the first content item can be displayed on the display unit 151. have. The first content description may include information on a first function related to the first content item. Accordingly, the controller 180 may consider that the user is familiar with the content corresponding to the description of the first content, and may set the first content not to be displayed during the second period.

After receiving the command to select the first content item, the controller 180 may detect whether a first function included in the description of the first content is executed. When the first function is not executed, the control unit 180 maintains a state in which the first content is not displayed for the second period, and when the first function is executed, it is considered that the user is fully familiar with the first function and the first content may not be displayed during the third period.

Here, the first period is shorter than the second period, and the second period is shorter than the third period. This is because, when the user is familiar with the first function, the need to display the content more often when not familiar with it is lowered, and when the user has viewed the first content, the need to display the content more often than when not viewed is lowered.

Through this, there is an advantage in that the case of continuously displaying the same content to the user can be minimized.

Again, FIG. 4 will be described.

When the first content item is not selected, the controller 180 may determine whether a time for displaying the first content item has elapsed as a reference time (S23).

The controller 180 may count the time at which each content item is displayed for each of a plurality of content items included in the content list, and determine whether the counted time for each content item has elapsed a reference time.

When the time for displaying the first content item does not elapse the reference time, the controller 180 may display a content list including the first content item ( S25 ).

That is, the controller 180 may control to display for a minimum reference time period even if a specific content item is not selected. Through this, there is an advantage in that it is possible to minimize the case where the user fails to check the required content and misses it. For example, the reference time may be 48 hours, but it is not limited thereto as this is only an example.

Meanwhile, when the display time of the first content item elapses the reference time, the controller 180 may set the first content item not to be displayed for the first period ( S27 ).

Here, the first period may be 2 months, but it is not limited thereto since it is only an example.

The controller 180 may set the first content item not to be displayed for the first period, and display a content list including other content items instead of the first content item ( S29 ).

Next, FIG. 10 is an exemplary diagram illustrating a display method when a content item included in a content list is not selected for more than a reference time in a mobile terminal according to an embodiment of the present invention.

The controller 180 controls the display unit 151 to display the content list 30 including a plurality of content items 31 to 35, and determines the display time of the content in each of the plurality of content items 31 to 25. can count (a) of FIG. 10 shows the content list 30 displayed by the display unit 151, and (b) of FIG. 10 may show the counted time for each content item. Referring to the example shown in (b) of FIG. 10 , the first content item 31 is displayed for 4 hours, the second content item 32 is displayed for 1 hour, and the third content item 33 is displayed for 1 hour. displayed, the fourth content item 34 may be displayed for 1 hour, and the fifth content item 35 may be displayed for 1 hour.

If the reference time is 4 hours, the controller 180 may determine that the display time of the first content item 31 has elapsed the reference time. Referring to (c) of FIG. 10 , the controller 180 may display another content item instead of a first content item whose display time has elapsed a reference time. That is, the controller 180 may display content items other than the first to fifth content items 31 to 35 . As shown in (d) of FIG. 10 , the controller 180 may initialize the count time of the first content item 31 and block it from being displayed for the first period. Also, the controller 180 may count the display time of another content item 36 to be newly displayed. In this case, the other content item 36 may be a content item selected based on the user action detected through steps S11 to S13.

In this way, if the user does not check the specific content for a predetermined time or more, the controller 180 determines that the user does not want to view the corresponding content any more, and can control the corresponding content not to be displayed, and the user can view the corresponding content later. In anticipation of the need, if the display condition is satisfied after the lapse of a predetermined time, the display may be controlled to be displayed again.

Again, FIG. 4 will be described.

Meanwhile, when receiving a command for selecting a first content item from the content list, the controller 180 may display a content content screen explaining the first function ( S31 ).

That is, when receiving a command for selecting the first content item, the controller 180 may display a first content content screen corresponding to the first content item, and the first content content screen includes a description of the first function can do.

Thereafter, the controller 180 may determine whether a command for displaying a content recommendation list has been received ( S33 ).

If the controller 180 does not receive the command for displaying the content recommendation list, the controller 180 may return to step S11 to receive various control commands. Upon receiving the command for displaying the content recommendation list, the controller 180 may determine whether the first function has been executed (S35).

That is, when a specific content item is selected from the content list and a content content screen is displayed, the controller 180 may detect whether a specific function included in the content content screen is executed.

If the first function has never been executed, the controller 180 may set the first content item not to be displayed for the second period ( S37 ), and display a content list including other content items instead of the first content item ( S37 ). S39).

On the other hand, if the first function has been executed, the controller 180 sets the first content item not to be displayed for the third period (S41), and displays a content list including another content item instead of the first content item. can be (S43).

11 to 12 are exemplary diagrams illustrating a different operation method depending on whether a specific function is executed after a specific content item is selected in a mobile terminal according to an embodiment of the present invention.

First, referring to FIG. 11 , (a) of FIG. 11 shows a method for the controller 180 to display a content list 30 including first to fifth content items 31 to 35 and display of each content item. A method of counting time is exemplarily shown. As shown in (b) of FIG. 11 , when the first content item 31 is selected from the content list 30 , the controller 180 displays the content content screen 40 of the first content item 31 . can The content screen 40 may include a content title 41 and a content description 42 including a first function. The first to fifth content items 31 to 35 may include different first to fifth functions, respectively. The first to fifth functions may refer to various functions executed in the mobile terminal 100 .

When the content content screen 40 corresponding to the first content item 31 is displayed, the controller 180 may block the first content item 31 from being displayed for the second period. That is, the controller 180 may display another content item 37 as shown in FIG. 12A and block the first content item 31 from being displayed for the second period.

Meanwhile, the controller 180 may detect whether the first function corresponding to the first content item 31 is executed after displaying the content content screen 40 corresponding to the first content item 31 . If the execution of the first function is not detected, the controller 180 may maintain the blocking of the first content item 31 from being displayed for the second period. However, when the execution of the first function is detected, the controller 180 may block the change so that the first content item 31 is not displayed for the third period. That is, the controller 180 may display another content item 38 as shown in FIG. 12B and block the first content item 31 from being displayed for the third period.

In this case, the third period may be a third period from the day the first content item 31 is selected. Also, the third period may be longer than the second period. For example, the second period may be 2 months and the third period may be 3 months, but these are merely examples for convenience of description, and thus need not be limited thereto.

In this way, when a specific content is selected, the mobile terminal according to an embodiment of the present invention may differently adjust the content re-recommendation time according to whether a function corresponding to the specific content is executed. Accordingly, there is an advantage in that it is possible to minimize the case of continuously displaying a function that the user already knows, and to re-recommend the corresponding content in case the user forgets a specific function.

Meanwhile, other content items 37 and 38 displayed by the controller 180 instead of the first content item 31 may be different depending on whether the first function is executed. Specifically, the controller 180 displays a content item based on the user action detected through steps S11 to S13, but displays a content item associated with a simple first function when the first function is not executed, and displays the first function When this is executed, a content item indicating an executable function associated with the first function and only after the first function is executed may be displayed. That is, when the first function is executed, the controller 180 may determine that the user's function use level has been upgraded, and may recommend a function more complex than the first function. That is, the mobile terminal according to an embodiment of the present invention may select and display a specific content item by reflecting the user's function usage level.

To this end, the server 200 may set rules for displaying different content items depending on when a content item is selected for each content item and when a function included in the content item is executed. For example, a rule of recommending a second content item having a second function when the first content item is selected and recommending a third content item having a third function when the first content item is selected and executed It may be set in the first content item. A detailed description thereof will be described later with reference to FIGS. 14 to 17 .

Again, FIG. 4 will be described.

The controller 180 sets the first content item not to be displayed for the first period in step S29, sets the first content item not to be displayed for the second period in step S37, and sets the first content item not to be displayed for the second period in step S41. It was set not to be displayed for 3 periods.

The controller 180 may determine whether each period has elapsed. That is, when the first content item is set not to be displayed for the first period in step S29, the controller 180 determines whether the first period has elapsed (S49), and in step S37, the first content item is displayed for the second period When it is set not to be not displayed, it is determined whether the second period has elapsed (S47), and when the first content item is set not to be displayed for the third period in step S41, it can be determined whether the third period has elapsed (S45).

When each set period has not elapsed, the controller 180 displays another content item instead of the first content item, and when each set period has elapsed, it can be determined whether the display condition of the first content is satisfied (S51) .

Here, the display condition of the content indicates a display condition according to a rule set for each content to be described later. For example, the display condition of the first content is when a selection command of a wide-angle camera icon is received or a content item related to a camera shooting mode. It may include a case of receiving a command to select . However, this is merely exemplary and need not be limited thereto.

If the display condition of the first content is not satisfied, the controller 180 may display another content item instead of the first content item.

However, if the display condition of the first content is satisfied, the controller 180 may display a content list including the first content item ( S53 ).

As described above, the mobile terminal according to an embodiment of the present invention may recommend a specific content by identifying a function mainly used by the user, a function of interest of the user, a function usage level of the user, and the like through a control command.

The mobile terminal according to an embodiment of the present invention may repeat the operation of displaying a content list by analyzing a user's control command to select a predetermined content. In this process, the controller 180 may block the same content a plurality of times and then set it to be recommended again.

13 is an exemplary diagram for explaining a method for a mobile terminal to block and re-recommend the same content a plurality of times according to an embodiment of the present invention.

The controller 180 may display a content recommendation list. The user may not read the first content item from the content recommendation list because it has not been selected for a predetermined time. In this case, if the first content is continuously displayed, the user may feel uncomfortable. Accordingly, the controller 180 may block the first content item not selected for a predetermined time or longer from being displayed for the first period.

When the content display condition is satisfied after the lapse of the first period, the controller 180 may re-recommend the blocked first content and display a content recommendation list including the first content. Thereafter, when the controller 180 detects execution of the first function corresponding to the first content, the controller 180 may set the first content not to be displayed for a third period. In this case, the third period may be longer than the first period. This is because, as described above, the controller 180 can determine that the user is familiar with the corresponding function when the corresponding function is executed.

When the content content display condition is satisfied again after the elapse of the third period, the controller 180 may re-recommend the blocked first content and display a content recommendation list including the first content. Thereafter, when the blocking condition of the first content is satisfied, the controller 180 may obtain and block the longest period among the previously set blocking periods. For example, if the first content is not selected, the control unit 180 should block it so that it is not displayed for the first period, but if there is a history of previously blocking display for the third period, it is not displayed during the third period. You can set blocking.

That is, the mobile terminal according to an embodiment of the present invention does not collectively re-recommend based on whether content is selected and whether a function is executed, but rather recognizes the user's level of use of the function through whether the user has already executed the function. In addition, there is an advantage that the content recommendation list can be configured so that the functions included in the mobile terminal can be efficiently used by re-recommending the function at a predetermined period in consideration of the case where the corresponding function is forgotten.

Meanwhile, each content may have a recommendation rule in order to recommend the content by more accurately analyzing the function of interest of the user of the mobile terminal according to the embodiment of the present invention, the level of use of the user's function, and the like. According to an embodiment, the server 200 may set a recommendation rule for each content, but since this is only an example, the subject who sets the recommendation rule is not limited. For convenience of explanation. It will be described as an example that the server 200 sets a recommendation rule for each content.

14 is a control block diagram of a server that transmits content to a mobile terminal according to an embodiment of the present invention.

The server 200 may include an input unit 210 , a storage unit 220 , a communication unit 230 , and a control unit 240 .

The input unit 210 may receive at least one of a category setting command, a function setting command, and a content addition command.

One content may include one category, one function, and one description. The type of the category to which the content belongs and the type of function may be input and set through the input unit 210 .

15 is a diagram illustrating a method for setting a category type according to an embodiment of the present invention, and FIG. 16 is a diagram illustrating a method for setting a function type according to an embodiment of the present invention.

Referring to FIG. 15 , the controller 240 may receive a command for inputting a category ID 265 and a category name 267 to set a category, and in some cases, the category may have an upper category 266 . .

Similarly, referring to FIG. 16 , the input unit 210 may receive a command for inputting a function ID 275 and a function name 277 to set a function, and in some cases, the function may have an upper function 276 . can

As such, according to an embodiment of the present invention, the server 200 may set a category or function, and if necessary, may add a new category and function. Accordingly, there is an advantage that the user can more accurately access a function similar to the function of interest and recommend it.

Also, the input unit 210 may receive a content addition command, and the content addition command may include a content title, content description, and content recommendation rule.

17 is an exemplary diagram illustrating a method for a server to add content according to an embodiment of the present invention.

Referring to FIG. 17, the input unit 210 includes at least one of a content ID 281, a content title 282, a model name 283, a category 284, a function 285, and a recommendation rule 286. A content addition command may be received.

The content ID 281 may be determined according to an addition order or may be determined by a user's manual input.

The content title 282 may be determined by an input received from a user.

The model name 283 may indicate the name of a model to which a function included in the corresponding content is applied. The controller 240 may control the content to be transmitted only to a model to which a function included in the content is applied based on the model name.

The category 284 and the function 285 are input to analyze the user's interest function, and may be set in the same manner as described with reference to FIGS. 15 to 16 .

The recommendation rule 286 is a content recommendation rule for recommending content, and may indicate a combination of content display conditions.

For example, the content display condition is when a command to select a specific icon included in the mobile terminal 100 is received, when a command to select a specific content is received and displayed, when a specific category score satisfies a reference score, a specific When the function score satisfies the reference score, a case in which a function corresponding to the content is executed after selecting a specific content may be included.

In this case, the content recommendation rule is a first rule when a command to select a specific icon is received, a second rule when a command to select a specific icon is received and a specific category score is 2 or more, and a specific content is displayed and a specific function is It may be set as a third rule that is executed.

Referring to FIG. 17 , the controller 240 may add content by selecting any one of rules named R1 to R5 to the content.

In this way, the controller 240 may set a content recommendation rule for each content by combining at least one of the content display conditions.

According to this, the user can select and set any one of the first rule, the second rule, or the third rule without setting the content display conditions individually when adding specific content, so that the corresponding content can be appropriately recommended. There is this. Therefore, when it is necessary to add new content, the user can easily add the content without much effort, and there is an advantage that more appropriate content can be recommended by reflecting the user's interest function and the user's level of use of the function. In addition, according to the content recommendation rule, it is possible to recommend content having different categories but having similar functions, so there is an advantage in that it is possible to recommend various functions that the user does not know included in the mobile terminal.

The controller 240 may set each content to have at least one recommendation rule, and may set a priority when there are conflicting recommendation rules.

Meanwhile, in some cases, the controller 240 may set the content to have a condition for determining execution of the content when setting the content.

The content execution judgment condition is to determine that the user is familiar with and executed the function included in the specific content. For example, if the content includes a description of the 'edit' function, the content execution judgment condition is the execution of the 'edit' function It may be a case of receiving a command to save the edited contents afterward. As such, the content execution determination condition may vary according to the content of each content, and may be set through the input unit 210 .

Again, FIG. 14 will be described.

The storage 220 may store a plurality of contents. That is, the storage unit 220 may store the corresponding content title, content description, content recommendation rule, content execution determination condition, and the like for each content.

Also, the storage 220 may store category scores for each category and function scores for each function. However, in some cases, the category score and the function score may be stored in the memory 170 provided in the mobile terminal 100 .

The communication unit 230 may transmit/receive data to and from the mobile terminal 100 . For example, the communication unit 230 may transmit at least one content to the mobile terminal 100 , and may receive information of a control command received by the mobile terminal 100 from the mobile terminal 100 .

The controller 240 may control the overall operation of the server 200 , and may control the input unit 210 , the storage unit 220 , and the communication unit 230 .

In the foregoing, the case of recommending content for describing various functions provided in the mobile terminal has been described as an example, but this is for convenience of description and need not be limited thereto. That is, the present invention is applicable to all cases of recommending information related to specific information.

The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer readable medium includes all kinds of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is this. In addition, the computer may include a control unit 180 of the terminal. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. 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.
