Meanwhile, the sensing unit 140 senses at least one of information in the digital signage, surrounding environment information surrounding the digital signage, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control the driving or operation of the digital signage 100 or perform data processing, functions, or operations related to an application program installed in the digital signage 100 based on the sensing signal. 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 in the vicinity of the touch screen.

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

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. 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 touch, an electrostatic capacitance at the time of 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, 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 control 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.

On the other hand, the above-described touch sensor and proximity sensor independently or in combination, a short (or tap) touch on the touch screen (short touch), long touch (long touch), multi touch (multi touch), drag touch (drag touch) ), flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch, etc. It can sense touch.

The ultrasonic sensor may recognize position 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 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 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 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 sensors using electrical signals that change according to the amount of light applied to the photo diodes.

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 is operated 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 setup parameters for Bluetooth and Wi-Fi connections 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.

The information 520 related to the object may be output to the second area 510b corresponding to the second position among the areas.

The first area 510a and the second area 520b are different from each other, and are determined according to a location where the object 500 is disposed, and the first and second areas 510a and 510b are different from each other. 500) may overlap at least a portion based on the arrangement position.

Hereinafter, a method of determining a position at which an object is disposed and a method of outputting information related to an object will be described in more detail with reference to FIG. 6 .

The digital signage 100 according to an embodiment of the present invention capable of including at least one of the above-described components may include at least one camera 121 . The camera 121 may be formed to face a region where an object is disposed. That is, the controller 180 may receive an image corresponding to an area in which an object is disposed through the camera 121 .

The controller 180 may determine a position where the object is disposed through the image received through the camera 121 , and determine an area corresponding to the determined position based on the determined position.

In the inactive state of the camera 121 , the camera 121 may be switched to an active state based on an object approaching the main body or the object being disposed around the main body 100 . In addition, the camera 121 may always be in an active state when the digital signage is turned on. Also, the camera 121 may be switched from an inactive state to an active state based on a control command (user control command) being applied from the outside.

The state change of the camera 121 may be performed under the control of the controller 180 .

When the camera 121 is in an activated state, the controller 180 may switch the activated camera 121 to an inactive state based on satisfying a preset condition.

For example, when no movement is detected for a preset time after the object is placed, when the object on which the object is placed moves away from the main body, the controller 180 controls the user to switch the activated camera to inactive Based on at least one of cases in which the command is applied, the camera 121 in the active state may be switched to the inactive state.

As shown in FIG. 6 , the controller 180 determines (determines) the position (eg, 600a, 600b, 600c) where the object is disposed based on the image received through the at least one camera 121 . can do.

Thereafter, the controller 180 may determine a region corresponding to the determined position among the display regions of the display unit 151 based on the determined position.

For example, when it is detected that the object 600 approaches the body 100 , the controller 180 may activate the camera 121 . Thereafter, when the object 600 is placed at the first position 610 by the user (object), the controller 180 moves the object 600 to the first position using the image received through the camera 121 . It can be determined that it is placed at 610 .

When the object 600 is disposed at the first location 600a, the controller 180 may determine the first area 610a corresponding to the first location as an area for outputting information related to the object 600 . have. As described above, the first area 610a includes a first position 600a at which the object 600 is disposed, the type of the disposed object 600 , the size of the disposed object 600 , and the object It may be determined based on at least one of the amount (size, type) of related information, or may be determined by a user setting.

Similarly, when the object 600 is disposed at the second location 600b, the controller 180 outputs information related to the object 600 in the second area 610b corresponding to the second location 600b. It can be determined as an area for Also, even when the object 600 is disposed at the third location 600c, the controller 180 sets the third area 610c corresponding to the third location 600c to information related to the object 600 . can be determined as an area for outputting .

On the other hand, the digital signage 100 of the present invention may determine the position where the object is disposed by using the sensing unit 140 instead of the camera 121 . The sensing unit 140 may sense the pressure applied to the cradle 630 that is formed so that the object can be placed (displayed, mounted). When pressure is sensed through the sensing unit 140 , the controller 180 may determine a position where the object is disposed based on the sensed pressure.

The digital signage 100 of the present invention may determine a position where an object is disposed by combining the camera and the detection unit described above.

When a region corresponding to the position is determined among the display regions of the display unit 151 based on the position where the object is disposed, the controller 180 displays information related to the object in the determined region on the display unit 151 ) can be controlled.

As described above, the controller 180 may extract information related to the object in various ways.

For example, the controller 180 identifies an object disposed around the main body 100 through the camera 121 , and stores information related to the identified object in the memory 170 or an external device (eg, a server). or from a terminal, etc.).

Specifically, when the object 600 approaches the main body 100 or the object 600 is disposed around the main body 100, the controller 180 acquires an image corresponding to the object 600 through the camera. can do. Thereafter, the controller 180 may identify the object 600 based on the acquired image. The controller 180 extracts information related to the object from the memory 170 or an external device by using the identification information of the identified object (eg, an image of the object or a unique number associated with the image) or receive.

As another example, the object 600 disposed around the main body 100 may be provided with a tag 650 capable of storing and transmitting its own information. For example, the tag may be an RFID tag (Radio Frequency IDentification) or a barcode (or QR code).

The controller 180 may control the wireless communication unit 110 (refer to FIG. 1 ) to receive information related to an object from the tag 650 .

Specifically, the object 600 may include a tag 650 configured to transmit information related to the object to the digital signage 100 through wireless communication. When the object 600 approaches the main body 100 or the object 600 is disposed around the main body 100, the controller 180 is configured to receive a signal (eg, beacon frame, wake-up) for receiving information. signal, etc.) can be generated. The tag 650 provided on the object 600 may transmit information related to the object to a device (eg, the digital signage 100 ) that generated the signal in response to the signal.

Based on the reception of the information related to the object, the controller 180 may output the received information related to the object to an area corresponding to the location where the object 600 is disposed.

In the above, the process of determining the location of the object, the process of determining the area corresponding to the location, and the process of extracting information related to the object have been described as sequentially occurring, but the present invention is not limited thereto, and the above processes are performed simultaneously or may be performed in a different order.

Also, based on the received specific information, the controller 180 may display an indicator indicating that there is an object corresponding to the specific information in an area corresponding to a location where the object corresponding to the received specific information is disposed. have.

Specifically, when an external device approaches the main body 100 , the controller 180 may control the wireless communication unit 110 to generate a signal for receiving information from the external device.

Here, that the external device approaches the main body 100 may mean that the external device enters within the preset range at a point out of the preset range with respect to the main body 100 . The preset range means a range in which the sensor 140 can sense the movement of an object, and may be set by a user or determined by a characteristic of the sensor 140 .

Referring to FIG. 7 , the control unit 180 may detect that the external device 200 approaches the main body 100 through the sensing unit 140 . The controller 180 may generate a signal (eg, a beacon frame or a wake-up signal) for receiving information from the external device 200 through the wireless communication unit 110 in response to the detection. have.

Here, as shown in the first drawing of FIG. 7 , specific information 210a corresponding to an object may be preset (stored) in the external device 200 . The specific information 210a corresponding to the object may be, for example, product information or a shopping list.

For example, an application capable of interworking with an application previously installed in the digital signage 100 may be installed in the external device (mobile terminal) 200 .

The application installed on the external device 200 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 210a may be previously selected (set or stored) by the user.

The external device 200 may transmit specific information 210a preset in the external device 200 to the device (digital signage 100) that has transmitted the signal in response to the signal.

The controller 180 may receive the specific information 210a through a wireless communication unit. Thereafter, the controller 180 may determine an object corresponding to the specific information 210a.

For example, if the specific information 210a corresponds to any one of the at least one object 700a, 700b, and 700c disposed around the main body 100, the controller 180 may As shown in the second figure of , an indicator 730 notifying that there is an object 700a corresponding to the specific information 210a in an area 710a corresponding to a position where the one object 700a is disposed. ) can be displayed.

7, when the information 720a related to the object 700a is displayed in the area 710a corresponding to the position where the one object 700a is disposed, The controller 180 may change the information 720a related to the object 700a to the indicator 730 .

The indicator can be implemented in any form as long as it has a form for informing that there is an object, and for example, may be in the form of a graphic object or an icon.

In addition, the display of the indicator may include that the graphic effect is changed.

Also, the indicator may be information different from information related to a coupon, advertisement, or a previously displayed object.

When the external device 200 moves away from the main body 100 , the controller 180 may make the indicator 730 disappear. If the information related to the object has been previously displayed before the indicator 730 is displayed, the controller 180 sets the indicator 730 to the information related to the object based on the external device 200 moving away from the main body 100 . can be restored with

Here, that the object (external device 200) moves away from the main body 100 means,

Through this configuration, when the user sets the item he or she wants to buy in advance, the user can find the desired item more quickly and conveniently during shopping, thereby improving convenience.

Meanwhile, the digital signage 100 may control screen information displayed on the display unit 151 in various ways based on the approach of the object.

Hereinafter, it will be described as an example that the object is a user. However, the object is not limited to the user, and may be applicable even to a device capable of wireless communication.

The sensing unit 140 provided in the digital signage 100 of the present invention may detect that an object is approaching (approaching) to the main body.

In this case, the controller 180 may output information related to an article disposed around the main body to the display unit 151 based on the approach of the object to the main body 100 .

For example, as shown in the first drawing of FIG. 8A , information related to an object may not be displayed on the display unit 151 . In this case, the state in which the information related to the object is not displayed may mean a state in which the display unit is in an inactive state or a state in which information different from the information related to the object is displayed.

Thereafter, when the control unit 180 detects that the object 850 approaches the main body 100 through the sensing unit 140 , as shown in the second diagram of FIG. 8A , the controller 180 moves around the main body 100 . Information 820 related to the disposed object may be output to the display unit 151 .

That is, the information 820 related to the object may be displayed based on the approach of the object 850 to the main body 100 in a state that is not displayed on the display unit 151 .

Thereafter, when it is sensed through the sensing unit 140 that the object 850 located on the periphery of the main body moves away from the main body 100 , the controller 180 , as shown in the third drawing of FIG. 8A , the object and The display unit 151 may be controlled so that the related information 820 disappears.

Meanwhile, the controller 180 may change the information related to the object displayed on the display unit 151 to other information based on the object 850 approaching the main body.

For example, as shown in the first drawing of FIG. 8B , information 820a related to an object disposed around the main body 100 may be previously displayed on the display unit 151 . At this time, as shown in the second drawing of FIG. 8B , when it is sensed that the object 850 approaches the main body 100 , the controller 180 transmits the object-related information 820a to the object-related information ( 820a) and other information 820b may be used.

The other information 820b may include information related to a previously displayed object 820a and information related to other objects among information related to objects disposed around the main body 100 . For example, when the object 850 approaches the main body 100 while the first information related to the object is displayed on the display unit 151 , the controller 180 transmits the first information related to the object to the object It is possible to change the first information related to the second information related to a different object.

Thereafter, when the object 850 located near the main body 100 moves away from the main body 100 while the other information 820b is displayed, the controller 180, as shown in the third diagram of FIG. 8B , , the other information 820b may be restored to information 820a related to the previously displayed object.

Through this configuration, the present invention can provide a new user interface that can control the output of screen information based on the approach of the object.

Hereinafter, a method of controlling the output of screen information of the display unit based on an external force applied to an object disposed around the digital signage will be described in more detail with reference to the accompanying drawings.

9A and 9B are conceptual views for explaining a method of outputting different screen information based on an external force applied to an object disposed around a digital signage according to an embodiment of the present invention.

The sensing unit 140 provided in the digital signage 100 according to an embodiment of the present invention, which can include at least one of the components as described above, is applied to an object disposed around the main body 100 . It can sense external forces.

For example, as described with reference to FIG. 6 , the sensing unit 140 may sense the pressure applied to the cradle 630 that is formed so that an object can be placed (displayed, mounted). When pressure is sensed through the sensing unit 140 , the controller 180 may determine that an external force is applied to the object based on the sensed pressure.

As another example, the controller 180 may detect that an external force is applied to an object disposed around the main body 100 through the camera 121 . Specifically, when detecting that an object approaches the main body 100 , the controller 180 may activate the camera 121 .

Thereafter, the controller 180 may determine a moving object among objects disposed around the main body 100 by using the image received through the camera 121 . The controller 180 may determine that an external force is applied to the moving object based on the moving object.

The controller 180 may display different screen information based on the number of times an external force is applied to the object.

For example, as shown in the first drawing of FIG. 9A , when an external force is first applied by the object 950a to the object 900 disposed around the main body 100 , the controller 180 controls the display unit 151 ) of the display area, the first information 920a related to the number of times the external force is applied may be displayed in a region corresponding to the position where the object 900 to which the external force is applied is disposed.

Thereafter, as shown in the second diagram of FIG. 9A , when a second external force is applied to the object 900 by the object 950b, the controller 180 provides the first information 920a in the corresponding area. The second information 920b related to the number of times an external force different from ? and ? may be displayed.

At this time, as shown in the first and second drawings of FIG. 9A , even when the objects to which the external force is applied to the object 900 are different from each other, the controller 180 controls the object 900 based on the number of times the external force is applied. Thus, different screen information can be output.

Through this configuration, the present invention can provide a user interface that can easily grasp the popularity, recommendation, preference, etc. of the object to the user by providing different information according to the number of times an external force is applied to the object.

Meanwhile, the controller 180 may output different screen information according to the type of the object that applies an external force to the object 900 .

The camera 121 provided in the digital signage 100 of the present invention may be formed to photograph an object. The controller 180 may identify an object that applies an external force to the object by using the camera 121 .

Specifically, when detecting that an object approaches the main body 100 , the controller 180 may activate the camera 121 . The controller 180 may identify an object approaching the main body 100 using an image received through the camera 121 . For example, the controller 180 may identify the object by extracting an image corresponding to the face of the object and extracting feature points from the image.

The controller 180 may identify an object that applies an external force to the object 100 using the camera 121 . Thereafter, the controller 180 may detect that the identified object moves away from the main body after applying an external force to the object and then comes back to the periphery of the main body. When the identified object approaches again, the controller 180 may output guide information informing that an external force has been previously applied to the object.

For example, as shown in the upper left of FIG. 9B , the first object 950a applies an external force to the object 900 disposed around the main body 100 , and then, as shown in the upper right of FIG. 9B , Likewise, it can move away from the main body 100 and then come back to the periphery of the main body (in the first case).

Also, the first object 950a may apply an external force to the object 900 disposed around the main body 100 and then apply the external force to the object 900 again (in the second case).

When at least one of the first and second cases is sensed as above, the controller 180, as shown in the upper right of FIG. 9B , guide information 930b notifying that an external force has been previously applied to the object 900 . ) can be printed.

In addition, before at least one of the first and second cases is sensed as above, as shown in the upper left of FIG. 9B , when information 930a related to the object 900 is displayed, the controller 180 controls the Based on detection of at least one of the first and second cases, the information 930a related to the object may be changed to guide information 930b indicating that an external force has been previously applied.

Meanwhile, as shown in the lower left of FIG. 9B , after a first object 950a applies an external force to the object 900 , a second object 950b different from the first object approaches the main body 100 . Or, when the second object 950b first applies an external force to the object 900 , the controller 180 may not output guide information indicating that the external force has been previously applied. When the object-related information 930a is displayed on the display unit 151 before the second object 950b applies an external force or approaches the main body 100, the object-related information 930a The output may be maintained even if the second object 950b applies an external force or the second object 950b approaches the main body 100 .

Through this configuration, the present invention can provide convenience, such as more easily finding an article previously viewed by the user, or preventing duplicate viewing by providing guide information on an article that the user has looked at before.

Hereinafter, a method for the digital signage of the present invention to output different screen information based on screen information output from an external image output device will be described in more detail with reference to the accompanying drawings.

The controller 180 determines a location where the object 1010b corresponding to information related to the received screen information (information related to the specific object 1010b) is disposed, and an area 1020b corresponding to the determined location. ) may display information related to the corresponding object.

On the other hand, as shown in FIG. 10B , the controller 180 determines a location where an object 1010b corresponding to information related to the received screen information (information related to the specific object 1010b) is disposed, and , a graphic effect applied to the area 1020b corresponding to the determined position may be changed.

Although not shown, the controller 180 may receive color information from the image output apparatus 1000 for each time. Also, the controller 180 may extract color information of the screen information 1100 output from the image output apparatus 1000 by using a camera, an illuminance sensor, an optical sensor, or the like.

The color information means information about a color included in screen information output from the image output apparatus 1000 .

The controller 180 may change the color of the display unit 151 based on the color information. For example, the controller 180 may extract the largest number of colors based on the production information, and apply a graphic effect related to the color to the background of the display unit 151 .

Through this configuration, the present invention can control the digital signage so that the position of the article output from the external image output device can be easily grasped.
