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 the inner region of the digital signage covered by the touch screen as described above or near 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. It can be printed on the touch screen. Furthermore, the controller 180 may control the digital signage 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. have.

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 a touch, an electrostatic capacitance at the time of a touch, etc. in which 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 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). 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 digital signage 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 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.

The display unit 151 displays (outputs) information processed by the digital signage 100 . For example, the display unit 151 may display execution screen information of an application program driven in the digital signage 100, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information. have.

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 digital signage 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 generally the overall operation of the digital signage 100 . For example, if the state of the digital signage 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 digital signage 100 according to the present invention, the controller 180 may control any one or a plurality of the components described above by combining them.

The power supply unit 190 includes a battery, and the battery may be a built-in battery configured to be rechargeable, and may be detachably coupled to the terminal body for charging or the like.

In addition, the power supply unit 190 may include a connection port, and the connection port may be configured as an example of the interface 160 to which an external charger that supplies power for charging the battery is electrically connected.

As another example, the power supply unit 190 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 190 uses one or more of an inductive coupling method based on a magnetic induction phenomenon or a resonance coupling method based on an electromagnetic resonance phenomenon from an external wireless power transmitter. power can be transmitted.

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

1, digital signage according to the present invention includes Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, NFC ( Near Field Communication), a short-distance communication technology such as Wireless Universal Serial Bus (USB) may be applied.

Among them, the NFC module provided in the digital signage supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a P2P mode. In order for the NFC module to operate in the card mode, the digital signage 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a Universal Integrated Circuit Card (UICC) (eg, a Subscriber Identification Module (SIM) or a Universal SIM (USIM)), a Secure micro SD, and a sticker, or a logical medium embedded in a digital signage. (eg, embedded Secure element (SE)). Data exchange based on SWP (Single Wire Protocol) may be performed between the NFC module and the security module.

When the NFC module is operated in card mode, digital signage can transmit stored card information to the outside like a traditional IC card. Specifically, when a mobile terminal that stores card information of a payment card such as a credit card or a bus card approaches a digital signage (or a fare payment machine), a mobile short-distance payment can be processed and the card information of the access card is stored. When the storing mobile terminal approaches the digital signage (or access approver), an access approval procedure may be started. Cards such as credit cards, transportation cards, and access cards are loaded in the security module in the form of an applet, and the security module may store card information about the loaded card. Here, the card information of the payment card may be at least one of a card number, balance, and usage history, and the card information of the access card is at least one of a user's name, number (eg, user's student number or company number), and access details. can be one

When the NFC module is operated in the reader mode, the digital signage may read data from an external tag. In this case, data received by the digital signage from the tag may be coded in a data exchange format determined by the NFC forum. In addition, the NFC forum defines four record types. Specifically, the NFC forum defines four Record Type Definitions (RTDs) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. When the data received from the tag is a smart poster type, the controller executes a browser (eg, an Internet browser), and when the data received from the tag is a text type, the controller executes a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a call, and when the data received from the tag is a general control type, an appropriate operation may be executed according to the control content.

When the NFC module operates in a peer-to-peer (P2P) mode, the digital signage may perform P2P communication with other terminals. In this case, a Logical Link Control Protocol (LLCP) may be applied to P2P communication. For P2P communication, a connection may be created between a digital signage and another terminal. In this case, the generated connection may be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and the like and setup parameters for Bluetooth and Wi-Fi connection may be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively utilized for exchanging small-sized data.

Here, the screen information may mean all information that can be output from the digital signage 100 . For example, the screen information may include an image, a moving picture, a template, a graphic object, an icon, an indicator, and the like.

For example, as shown in FIG. 3A , the first display unit 151a may be provided on the front surface of the main body, and the second display unit 151b may be provided on the rear surface of the main body. In this case, screen information may be output through the first display unit 151a on the front surface of the main body, and screen information may be output through the second display unit 151b on the rear surface of the main body.

When the first display unit 151a and the second display unit 151b are respectively formed on the front surface of the main body and the rear surface of the main body, the first and second display units 151a and 151b are transparent display units capable of adjusting transparency. can When the first and second display units 151a and 151b are formed as transparent display units, the user can view an object located opposite the digital signage 100 through the first and second display units 151a and 151b. can see.

As another example, the digital signage 100 of the present invention may include a transparent display unit 151c as shown in FIG. 3B . When one transparent display unit 151c is formed in the digital signage 100, the front surface of the transparent display unit 151c corresponding to the front surface of the main body and the rear surface of the transparent display unit 151c corresponding to the rear surface of the main body are respectively Screen information may be output. In addition, in the digital signage 100 , as shown in FIG. 3A , two transparent display units may be provided on the front and rear surfaces of the main body, respectively.

Although not shown, the digital signage 100 may be provided with a display unit on the side as well as the front and rear of the main body.

Through this configuration, the digital signage 100 according to an embodiment of the present invention may output screen information to the front and rear surfaces of the main body, respectively. In addition, the digital signage 100 is located in the direction in which any one side (eg, front) of the body faces in the space that is opposite to the one side (eg, the rear) is facing. It may be formed so that the space is visible.

Hereinafter, for convenience of explanation, it will be described that screen information is displayed on the front (or rear) of the main body in digital signage. Here, that screen information is displayed on the front (or rear) of the main body means that screen information is displayed on a display unit provided on the front (or rear) of the main body or that screen information is displayed on the front (or rear) of the transparent display unit could mean to be

In addition, in the following description, reference numeral 151a is described on the front side of the main body and reference numeral 151b is described on the rear surface of the main body. Reference numeral 151a denotes a front surface of the display unit or transparent display unit provided on the front surface of the main body, and reference numeral 151b denotes a rear surface of the display unit or transparent display unit provided at the rear surface of the main body.

In addition, hereinafter, the same reference numeral 100 will be used for the digital signage and the main body.

Hereinafter, a method for controlling a digital signage 100 according to an embodiment of the present invention that can include at least one of the above-described components will be described in more detail with reference to the accompanying drawings.

4 is a flowchart representatively illustrating a control method of the present invention, and FIG. 5 is a conceptual diagram illustrating the control method illustrated in FIG. 4 .

In the present invention, the step of detecting an object approaching to the main body is performed (S410). Specifically, the digital signage 100 may include a sensing unit 140 (or a sensing unit) that detects that an object approaches the body. The sensing unit 140 may be the sensing unit 140 described with reference to FIG. 1 . That is, the control unit 180 may determine whether an object approaches the body through the sensing unit 140 .

When the object approaches the main body, it may mean that the object enters the preset range from a place out of a preset range with respect to the main body.

Here, referring to FIG. 5 , the object 500 may include, for example, all kinds of objects (or tangible objects) made of materials such as people, human hands, and external devices (eg, mobile terminals). can

Thereafter, in the present invention, based on the approaching direction of the object, the step of outputting screen information to any one of the front and rear surfaces of the front of the main body is performed (S420).

The controller 180 may detect in which direction the object 500 approaches with respect to the main body 100 by using the sensing unit 140 . Based on the detection result, the controller 180 may control the display units 151a and 151b to output screen information on either one of the front surface 151a and the rear surface 151b of the main body.

For example, as shown in the first drawing of FIG. 5 , when the object 500 approaches the front surface 151a of the main body, the controller 180 displays the screen information 300a on the front surface 151a of the main body. can be displayed. In addition, as shown in the second drawing of FIG. 5 , when the object 500 approaches the rear surface of the main body, the controller 180 may display the screen information 300b on the rear surface 151b of the main body. have.

Here, screen information displayed on the front surface 151a of the main body or the rear surface 151b of the main body may vary depending on the type of an object approaching the main body. The related contents will be described later with reference to FIGS. 9 to 11 .

Meanwhile, the controller 180 may output different screen information to the front surface 151a and the rear surface 151b of the main body based on the direction in which the object 500 approaches. Specifically, the controller 180 may control the display units 151a and 151b to display different screen information on the front and rear surfaces of the main body based on the approaching direction of the object 500 .

For example, as shown in the first drawing of FIG. 5 , when the object 500 approaches the front surface 151a of the main body, the first screen information 300a may be output to the front surface 151a of the main body. have. In addition, as shown in the second drawing of FIG. 5 , when the object 500 approaches the rear surface 151b of the main body, the second screen information 300a and the second screen information different from the first screen information 300a are displayed on the rear surface 151b of the main body. Screen information 300b may be output.

That is, the controller 180 may output screen information on any one of the front surface 151a and the rear surface 151b of the main body based on the direction in which the object 500 approaches the main body.

In this case, even when the same object 500 approaches the main body 100 , the controller 180 may output different screen information to the front and rear surfaces of the main body.

The screen information described above is, for example, information related to an approaching object (eg, a name, a photographed image, etc.), screen information pre-stored in a digital signage, and received from an external device (eg, a server or other terminal). One screen information (eg, advertisement, coupon, etc.), screen information generated based on information received from an external device (eg map information, route information), and a screen related to the number of objects that have passed through the digital signage Information (eg, number of people, waiting time, etc.) may be included.

Through this configuration, the present invention provides various screen information to the user by outputting screen information to any one surface located on the approaching side of the object 500 and outputting different screen information according to the direction in which the object approaches. can do.

Hereinafter, a method of outputting screen information when the digital signage 100 according to an embodiment of the present invention capable of including at least one of the components as described above is rotated by an external force is shown in the accompanying drawings. It will be described in more detail with reference.

6A, 6B, and 6C are conceptual views for explaining a method of outputting screen information when a digital signage is rotated according to an embodiment of the present invention.

As described above, the digital signage 100 of the present invention may be formed in the form of a door. In this case, the digital signage 100 may be installed, for example, in a rotatable form based on any one axis. For example, when the digital signage 100 is installed in the form of a hinged door, the digital signage 100 may be rotated on the basis of any one axis (eg, stonework) by an external force.

Here, the external force refers to a force applied from the outside of the digital signage, and for example, an object (person) may refer to a pushing force or a pulling force to the digital signage 100 .

The sensing unit 140 may detect that the main body 100 is rotated based on any one axis 600 by an external force. Specifically, the control unit 180 may sense that the main body 100 is rotated by an external force using the sensing unit 140 . Also, the controller 180 may sense a direction in which the main body 100 is rotated using the sensing unit 140 .

The controller 180 may output screen information to any one of the front surface 151a and the rear surface 151b of the main body based on the direction in which the main body 100 is rotated. Specifically, the controller 180 rotates the main body 100 based on any one axis 600 in a state in which screen information is output on any one of the front surface 151a and the rear surface 151b of the main body. Based on this, the screen information displayed on the one surface may be output to any one surface of the front surface 151a and the rear surface 151b of the main body. That is, the controller 180 outputs the screen information output on any one surface as it is on the one surface based on the direction in which the main body 100 is rotated, or outputs the screen information to the surface opposite to the one surface. can do it

For example, as shown in FIG. 6A , the controller 180 displays the screen information 610 on any one of the front surface 151a and the rear surface 151b of the main body (eg, the front surface 151a). ) is output, when the main body 100 is rotated in the direction 650a in which the one surface 151a faces, the screen information 610 is displayed instead of the one surface (front 151a). It may be displayed on a surface different from the one surface (eg, the rear surface 151b). This may be a case in which a user (object) pulls the digital signage.

In this case, the output of the screen information 610 may be limited or maintained on any one surface.

As another example, as shown in FIG. 6B , the controller 180 displays screen information 610 on any one of the front surface 151a and the rear surface 151b of the main body (eg, the front surface 151a). In the output state, when the main body 100 is rotated in a direction 650b opposite to the direction in which the one surface (front 151a) faces, the screen information on the one surface 151a output can be maintained. This may be the case when the user (object) pushes the digital signage.

On the other hand, when it is sensed that the main body 100 is rotated based on one of the axes 600 , the controller 180 may change the screen information displayed on any one of the front and rear surfaces of the main body to other screen information. have.

For example, as shown in FIG. 6C , when the main body 100 is rotated in a state where the first screen information 610a is displayed on any one of the front surface 151a and the rear surface 151b of the main body, the control unit At 180, the first screen information 610a may be changed to second screen information 610b different from the first screen information 610a.

At this time, as described with reference to FIG. 6A , when the second screen information 610b is rotated in the direction that the one side faces (when the user pulls the digital signage), the second screen information 610b is opposite to the one side. can be displayed on the side.

In addition, as described with reference to FIG. 6b , the second screen information 610b is rotated in a direction opposite to the direction in which the one surface faces (when the user pushes the digital signage), the one surface output can be maintained.

Through this configuration, according to the present invention, when the digital signage is rotated, the screen information displayed on the digital signage can be exposed to the object (user) for a longer time, so that more useful information can be provided for a long time from the user's side, , in terms of advertisers, there is an effect that the advertisements they want can be exposed to users for a longer period of time.

Hereinafter, a method of adjusting the transparency of the digital signage 100 according to an embodiment of the present invention that can include at least one of the components as described above will be described in more detail with reference to the accompanying drawings. see.

7A and 7B are conceptual diagrams for explaining a method of controlling the transparency of a digital signage according to an embodiment of the present invention.

As described above with reference to FIGS. 3A and 3B , the transparency of the display unit 151 provided in the digital signage 100 of the present invention may be controlled by the control of the controller 180 .

The controller 180 may adjust the transparency of the display unit 151 based on the approach of the object 710 to the main body 100 .

For example, as shown in the first drawing of FIG. 7A , the display unit 151 of the digital signage 100 may be in a transparent state 700a. Here, the transparent state 700a may mean a state in which another space located opposite the digital signage is visible in one space. In this case, the transparent state 700a may be a state in which no graphic effect is applied, or a state in which at least some graphic effects are applied so that another space located opposite the digital signage is visible in one space.

In this state, when it is sensed that the object 710 approaches the main body 100 , the controller 180 controls the object 710 among the front and rear surfaces of the main body as shown in the second diagram of FIG. 7A . The display unit 151 may be switched to an opaque state 710b so that screen information is displayed on the approaching surface.

Specifically, the controller 180 controls the display unit 151 so that the display unit 151 is switched from the transparent state 700a to the transparent state 700a to the opaque state 700b based on the approach of the object 710 in the transparent state 700a. ) can be controlled.

Here, in the opaque state 700b, screen information is displayed not only in a state in which another space located opposite the digital signage is not visible in one space, but also in a state in which another space located opposite the digital signage is visible in one space. It may include a state of being That is, the transition of the display unit 151 from the transparent state 700a to the opaque state 700b may mean that the transmittance of light passing through the display unit 151 (digital signage) is reduced.

Also, the sensing unit 140 may detect that the object 710 moves away from the main body 100 . Specifically, the controller 180 may detect that an object 710 adjacent to the main body 100 moves away from the main body 100 using the sensing unit 140 .

When the object moves away from the main body, it may mean that the object moves out of the preset range within a preset range with respect to the main body.

When the object 710 is adjacent to the body 100, the display unit 151 may be in an opaque state 700b as screen information is displayed. The controller 180 may switch the display unit 151 to a transparent state 700a based on the object 710 moving away from the main body 100 while the display unit 151 is in an opaque state. .

In other words, when the object 710 moves away from the main body 100 , the controller 180 may make the screen information output to the display unit 151 disappear.

Similarly, the transition of the display unit 151 from the opaque state 700b to the transparent state 700a may mean that the transmittance of light passing through the display unit 151 (digital signage) is increased.

Through this configuration, the present invention restricts the output of screen information (maintaining a transparent state) when an object approaches or is not adjacent, and outputs screen information (transparent state to opaque state) when an object approaches or adjoins. can be switched). Accordingly, according to the present invention, it is possible to adjust the transparency of the display unit based on the proximity of the object, as well as to save the battery consumed for outputting screen information.

Hereinafter, with reference to the accompanying drawings for various embodiments related to the output of screen information of the digital signage 100 according to an embodiment of the present invention that can include at least one of the components as described above. Let's look at it in detail.

8A, 8B and 8C are conceptual views for explaining a method of outputting screen information when an object approaches or moves away from a digital signage according to an embodiment of the present invention.

When an object approaches the main body 100 , the controller 180 may output screen information on the front surface 151a and the rear surface 151b of the main body. Specifically, the controller 180 may output screen information to both the front surface 151a and the rear surface 151b of the main body based on an object approaching the main body 100 .

In this case, the controller 180 may output different screen information to the front surface 151a and the rear surface 151b of the main body. Specifically, based on an approaching object, first screen information may be output to the front surface 151a of the main body, and second screen information different from the first screen information may be output to the rear surface 151b of the main body.

For example, as shown in FIG. 8A , when an object 800a approaches, the controller 180 outputs the first screen information 810a to the front surface 151a of the main body, and the rear surface 151b of the main body. ), the second screen information 810b different from the first screen information 810a may be output.

Here, as an example, when the object 800a approaches one of the front surface 151a and the rear surface 151b of the main body, the control unit 180 controls a preset range from the surface opposite to the one surface. When there is an object 800b different from the object 800a within the body, different screen information may be output to the front surface 151a and the rear surface 151b of the main body.

For example, as shown in FIG. 8A , in a state in which the first object 800b exists within a preset range from the rear surface 151b of the main body, the first object 800b moves toward the front surface 151a of the main body. When a second object 800a that is different from that of the second object 800a approaches, the controller 180 may output different screen information 810a and 810b to the front surface 151a and the rear surface 151b of the main body.

As another example, as shown in FIG. 8B , when the object 800a approaches any one of the front surface 151a and the rear surface 151b of the body, the object 800a is on the opposite surface to the one surface. ) and other objects do not exist, the controller 180 may output the screen information 810c on only one of the surfaces.

At this time, referring to FIGS. 8A and 8B together, the control unit 180, depending on whether an object exists on a surface opposite to the one surface, provides different screen information on the one surface to which the object approaches. can be printed out.

For example, when the first object 800b exists on a surface opposite to the one surface, the first object 800b is located on the one surface 151a as shown in FIG. 8A . The first screen information 810a may be output based on the approach of the second object 800a different from the one of the one surface 151a. On the other hand, as shown in FIG. 8B , when the first object does not exist on the surface opposite to the one surface, on the one surface 151a, as illustrated in FIG. 8B , the first object is not present. The second screen information 810c different from the first screen information 810a may be output based on the approach of the second object 800b different from the object to the one surface 151a.

Meanwhile, the controller 180 may change the output screen information to other screen information based on the object moving away from the main body in a state in which screen information is output to the front surface 151a and the rear surface 151b of the main body.

For example, as shown in FIG. 8C , when the object 800a moves away from the front surface 151a of the main body while screen information is output on the front surface 151a and the rear surface 151b of the main body, the rear surface of the main body At 151b, the output screen information may be changed to other screen information.

In addition, although not shown, when the object 800b moves away from the front surface 151a of the main body in a state in which screen information is output on the front surface 151a and the rear surface 151b of the main body, the output on the front surface 151a of the main body Screen information may disappear.

In addition, although not shown, in a state in which screen information is output on any one surface of the front surface 151a and the rear surface 151b of the main body, when an object located around the one surface moves away from the one surface, The screen information output on any one of the surfaces may also disappear.

Through this configuration, the present invention can output different screen information to the front and rear of the main body based on the approach of the digital signage 100 object. Also, according to the present invention, screen information may be output to at least one of the front and rear surfaces of the main body based on whether an object already exists around the main body. Also, according to the present invention, different screen information may be output to the surface to which the object and the other object approach, depending on whether an object already exists in the vicinity of the main body. Also, according to the present invention, screen information output to at least one of the front and rear surfaces of the main body may be changed based on the object moving away from the main body. Accordingly, according to the present invention, screen information optimized according to whether an object already exists in the vicinity of the main body can be provided to an object already existing in the vicinity of the main body and an object different from the object.

Hereinafter, various control methods of the digital signage 100 according to an embodiment of the present invention that can include at least one of the components as described above will be described in more detail with reference to the accompanying drawings.

9, 10A, 10B, and 11 are conceptual views for explaining various embodiments performed when an object approaches a digital signage according to an embodiment of the present invention.

First, referring to FIG. 9 , the digital signage 100 of the present invention may include a camera 121 disposed on at least one of the front and rear surfaces of the main body. The camera 121 may be the camera described in FIG. 1 .

When an object approaches the main body, the controller 180 may output screen information related to the approaching object to at least one of the front and rear surfaces of the main body using the image received through the camera 121 .

Specifically, when an object approaches the main body 100 , the controller 180 may activate the camera 121 disposed on the surface to which the object approaches. The controller 180 may recognize (identify) the approaching object using an image (or a preview image) received through the activated camera 121 .

Here, the controller 180 may analyze the image received through the camera 121 to determine the approaching object. For example, the controller 180 compares an image corresponding to an object included in an image received through the camera with an image pre-stored in a memory or an external device (eg, a server), and based on the comparison result, the Information related to an object can be extracted from memory or received from an external device.

For example, when the object is a person, the controller 180 compares an image corresponding to a person approaching the main body 100 with an image pre-stored in a memory or an external device, and extracts information related to the approaching person from the memory or It can be received from an external device.

Thereafter, the controller 180 may output screen information related to the object to at least one of the front surface 151a and the rear surface 151b of the main body using the image received through the camera.

The screen information related to the object includes an image captured by the camera, a pre-stored image corresponding to the image corresponding to the object, and pre-stored information (eg, name, phone number, address, number of visits, points, coupons, purchase history, visit date, etc.).

Meanwhile, different screen information related to the approaching object may be output on the front surface 151a and the rear surface 151b of the main body.

For example, as shown in FIG. 9 , when the object 900 approaches the main body 100 , the controller 180 may activate the camera 121 provided on the surface to which the object 900 approaches. have. Also, the controller 180 may identify the approaching object 900 using the image received through the camera 121 .

Thereafter, the controller 180 may output screen information related to the approaching object to at least one of the front surface 151a and the rear surface 151b of the main body. For example, any one 910 of the screen information output to the front surface 151a and the rear surface 151b of the main body is an image of the approaching object 900 or a flag corresponding to the approaching object 900 . It may be a saved image.

As another example, first information (eg, point information) 920a among pre-stored information corresponding to the approaching object 900 is output on the front surface 151a of the main body, and the rear surface 151b of the main body outputs the Among the information corresponding to the approaching object 900 , second information (eg, number of visits) 920b different from the first information may be displayed.

Meanwhile, the digital signage 100 of the present invention may further include the wireless communication unit 110 described with reference to FIG. 1 .

When it is sensed that an object approaches the main body 100 , the controller 180 may control the wireless communication unit 110 to receive information from the object. Here, the object may be an external device capable of wireless communication (eg, the mobile terminal 1000).

When information is received from the object 1000 , the controller 180 may display screen information related to the received information on at least one of the front surface 151a and the rear surface 151b of the main body.

Referring to FIG. 10A , information 1001 received from the object 1000 may be, for example, product information or a shopping list.

For example, in the object (mobile terminal) 1000, an application capable of interworking with an application previously installed in the digital signage may be installed.

The application installed on the object may be a shopping-related application that provides information on items that can be purchased at a place (eg, a store) where the digital signage 100 is installed.

In the shopping-related application, item information 1001 may be pre-selected by the user.

The controller 180 of the digital signage 100 may receive the article information 1001 based on the approach of the object 1000 . Thereafter, based on the received information, the controller 180 may display screen information 1010 related to the received information on at least one of the front surface 151a and the rear surface 151b of the main body.

For example, as shown in FIG. 10A , when the object 1000 approaches, the controller 180 receives information 1001 from the object 1000, and displays the information 1001 on the approaching surface 151a of the object. Screen information 1010 related to the received information may be output.

Here, the screen information 1010 related to the received information may be, for example, map information indicating a point at which an article corresponding to the received information 1001 exists, or route information.

Meanwhile, when it is sensed that the object 1000 approaches, the controller 180 may transmit content to the object 1000 through the wireless communication unit 110 . Here, the content may be a coupon, advertisement, store information, or the like.

Here, the content transmitted to the object 1000 may vary according to a direction in which the object 1000 approaches the main body.

For example, as shown in FIG. 10B , when the object 1000 approaches the front surface 151a of the main body, the controller 180 may transmit the first content 1020a to the object 1000 . Also, when the object 1000 approaches the rear surface 151b of the main body, the controller 180 may transmit the second content 1020b different from the first content 1020a to the object 1000 .

Through this configuration, the present invention provides different contents when the user visits and leaves the store, so that the user can be provided with various contents, and the advertiser provides various advertisements or induces continuous visits to the user. can do.

Meanwhile, the digital signage 100 of the present invention may output screen information related to the number of objects that have passed through the digital signage to at least one of the front and rear surfaces of the main body.

Referring to FIG. 11 , the sensing unit 140 may detect an object moving between one space and the other space with respect to the main body 100 . Here, the one side space 1100a may be a space located in a direction in which the front surface 151a of the main body faces, and the other side space 1100b may be a space located in a direction in which the rear surface 151b of the main body faces.

The sensing unit 140 includes a proximity sensor 141, an illumination sensor 142, a touch sensor, an acceleration sensor, a motion sensor, and an infrared sensor (IR sensor). : infrared sensor), ultrasonic sensor, optical sensor (eg, camera (see 121)), environmental sensor (eg, thermal sensor, etc.), chemical sensor (eg, electronic nose, healthcare sensor, biometric sensor, etc.) to detect the number of objects moving from the one side space to the other side space or from the other side space to the one side space with respect to the body 100 based on the main body 100 . can do.

The controller 180 may determine the number of objects existing in the one side space 1100a and the other side space 1100b based on the detection result. For example, when the other space 1100b corresponds to a store, the controller 180 may determine the number of objects existing in the store.

The controller 180 may determine the number of objects existing in any one of the one space and the other space (eg, the other space 1100b) based on the sensing result. Thereafter, based on the approach of the new object to the main body, the controller 180 may output screen information related to the number of objects existing in the one space on the surface to which the object approaches.

For example, as shown in FIG. 11 , when three objects 1120a, 1120b, and 1120c are placed in the space 1100b on the other side, the controller 180 controls the new object 1120d in the space 1100a on the one side. Screen information related to the number of objects existing in the space 1100b on the other side based on the approach to the main body in 1150 may be output to a surface (one surface 151a) disposed to face the one side space 1100a.

Here, the other side space 1100b may mean a space located in a direction in which a surface 151b opposite to any one surface 151a to which the new object 1120d approaches is directed.

The screen information 1150 related to the number of objects may include information on the number of objects, waiting time information, and the like. That is, the screen information 1150 related to the number of objects may mean state information of one space or the other space based on the digital signage.

Through this configuration, according to the present invention, when a user enters a store through a digital signage, the state in the store can be grasped in advance before entering the store, thereby improving user convenience.

As described above, the present invention can output screen information to any one of the front and rear surfaces of the digital signage based on the approaching direction of the object, and output different screen information to the front and rear surfaces of the digital signage. Accordingly, the present invention can provide a new user interface that outputs different screen information according to an approaching direction of an object.

In addition, the present invention can detect the rotation of the digital signage and perform different controls on the screen information output based on the rotation direction. Accordingly, the present invention can provide a method for outputting screen information optimized according to the rotation of the digital signage in the digital signage formed in the shape of a door.

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 also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. In addition, the computer may include the control unit 180 of the terminal. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary.
