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. 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.

Two or more haptic modules 153 may be provided according to the configuration of the digital signage 100 .

The light output unit 154 outputs a signal for notifying the occurrence of an event by using the light of the light source of the digital signage 100 .

Next, a communication system that can be implemented through the digital signage 100 according to the present invention will be described with reference to FIG. 2 . The communication system of the terminal 200 described in FIG. 2 may also be applied to the digital signage 100 .

First, the communication system may use different air interfaces and/or physical layers. For example, the air interfaces available by a communication system 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. 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 200 , at least one base station (Base Station, BS (also referred to as Node B or Evolved Node B)) 270 , and at least one base station controller (Base Station). Controllers, BSCs) 275 , and a Mobile Switching Center (MSC) 280 . The MSC 280 is configured to be connected to a Public Switched Telephone Network (PSTN) and the BSCs 275 . The BSCs 275 may be connected in pairs with the BS 270 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.

The intersection of sector and frequency allocation may be referred to as a CDMA channel. The BS 270 may be referred to as a base station transceiver subsystem (BTSs). In this case, one BSC 275 and at least one BS 270 may be collectively referred to as a “base station”. A base station may also refer to a “cell site”. Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

The digital signage according to the present invention includes a display unit disposed in a public facility such as a stadium, and provides information related to the public facility to an unspecified number through the display unit (eg, real-time shooting information for a specific area of the public facility) etc) can be provided. In addition, when a specific event occurs in the public facility, the digital signage according to the present invention may additionally provide information related to the public facility and other information using a specific visual effect. Accordingly, the user may be provided with the information related to the public facility and the other information through the display unit to be differentiated according to various visual effects.

Hereinafter, digital signage and a control method thereof according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The drawings attached to this specification will be described in order based on a clockwise direction.

3A is a flowchart related to a control method for providing visual information through digital signage according to the present invention, and FIGS. 3B and 3C are representative views showing an embodiment related to a digital signage control method according to the present invention .

First, the digital signage according to the present invention may be applied to a specific space such as a large sports stadium or a public facility. In addition, an output state of screen information output to the display unit may be variously controlled under the condition of occurrence of a specific event in the specific space. Here, whether the specific event occurs may be determined by detecting a sound generated in the specific space.

Referring to FIG. 3A , the digital signage according to the present invention may detect a sound generated in the specific space by using a sensing unit (S310).

The digital signage may include a plurality of sensing units for detecting various sounds generated in the specific space. For example, the sensing unit may measure the frequency, intensity, etc. of the sound by using a microphone, a decibel meter, or the like.

Also, image information photographed in one area of the specific space may be output to the display unit (S320).

That is, the digital signage may arrange at least one display unit in the specific space, and output a photographing screen for one area of the specific space through the at least one display unit. The at least one display unit may be arranged in various sizes and shapes according to a position arranged in the specific space.

For example, a display unit having a preset size may be disposed in a soccer stadium or a baseball stadium, and a real-time shooting screen related to the soccer game and the baseball game may be output on the display unit. That is, as shown in the first drawings of FIGS. 3B and 3C , the display unit may be disposed in one area of the spectator's seat of the soccer stadium, and the real-time shooting screen 10 related to the soccer game may be output on the display unit. Through this, a plurality of users who use the stadium can be provided with more specific and detailed information about the sports game.

In a state in which the image information is output to the display unit, if the sound sensed in the specific space satisfies a preset condition, image information may be output on the image information (S330).

The preset condition may be a criterion for determining whether the sound sensed in the specific space corresponds to a specific event. More specifically, the preset conditions include a decibel (magnitude) range of the sensed sound, whether the sound corresponds to a specific frequency region, a time for which the sound is sensed, the presence or absence of regularity of the sound, and the repetition of the sensed sound regularly. It may be associated with at least one of the number of times.

For example, the controller 180 of the digital signage may determine that the specific event has occurred when the sound sensed in the specific space through the sensing unit corresponds to a preset decibel range. As another example, the controller 180 may determine whether the specific event occurs by determining whether the sound sensed in the specific space is sensed in a preset decibel range for a preset time.

In this way, when it is determined that the specific event has occurred, the image information may be output on the image information. As described above, the image information may be image information photographed for one region of the specific space. To this end, the digital signage may include at least one camera to capture the image information. In addition, the digital signage may receive a photographing screen for one area of the specific space from an external server through a wireless communication unit.

The image information may be visual information including a preset image, text, or video. For example, the image information may be advertisement image information including promotional content for a specific product or service. As another example, it may be image information that is output based on the occurrence of a disaster warning sound (eg, fire, etc.) in the specific space and includes information such as the disaster situation and evacuation tips.

The image information may be output on the image information. That is, the image information may be output while being superimposed on at least a portion of the image information, or may be overlapped on the image information.

As such, the method of outputting the image information to the image information may vary depending on the sound sensed in the specific space. That is, the controller 180 may determine an output method of the image information based on the type of the detected sound (S340).

The sensed sound may be set to various types in relation to the preset condition. For example, when the preset condition is the decibel range of the sensed sound, different types of sounds may be configured according to the decibel range corresponding to the sensed sound.

That is, the controller 180 may determine that the sensed sound corresponds to the first decibel range and the second decibel range to be different types of sound. For example, as shown in the second diagram of FIG. 3B , a sound corresponding to a first decibel range in the specific space may be detected through a plurality of sensing units disposed in the specific space. Also, as shown in the second diagram of FIG. 3C , a sound corresponding to a second decibel range different from the first decibel range may be detected through the plurality of sensing units.

As another example, a case in which the sensed sound lasts for a first preset time in the first decibel range and a case in which the detected sound lasts for a preset second time in the first decibel range may be classified into different types of sounds. .

In this way, the controller 180 may determine a method in which the image information is output to the image information according to the type of the sensed sound. More specifically, the controller 180 may adjust the size, range, position, transparency, overlapping time, etc. of the image information overlapping the image information based on the type of the detected sound. In addition, when the image information gradually overlaps while moving on the image information, the speed, direction, and transparency of the image information may be adjusted differently.

For example, in the case of FIG. 3B , when the sensed sound corresponds to a first decibel range, the controller 180 moves the image information 11 and overlaps the image information 11 on the display unit (151) can be controlled. In this case, the image information 11 may start to be output on the image information 10 from a specific direction, and may move to overlap gradually up to a preset range of the image information 10 .

As another example, in the case of FIG. 3C , when the sensed sound corresponds to a second decibel range different from the first decibel range, the controller 180 places the image information 11 in one area of the image information 10 . ) may be controlled to overlap the display unit 151 in a stopped state. Accordingly, as shown in the third diagram of FIG. 3C , the image information 11 may be output to overlap one area of the image information 10 with a preset size.

The controller 180 may output the image information on the image information for a preset time. When the preset time elapses, as shown in the fourth diagram of FIG. 3C , the image of the image information corresponding to the time when the image information is output may be output again to the display unit 151 .

As described above, the signage according to the present invention may provide new image information on previously output image information based on the satisfaction of a preset condition for a sound sensed in a specific space. More specifically, it is possible to detect a specific event such as a shout generated by an unspecified number in a situation such as a score in a stadium, and provide specific advertisement image information to video information about the game.

Also, an output method of the image information may be variously controlled according to the type of the sensed sound. For example, in a situation in which a score has occurred, the image information may be overlapped and output on the image information by moving the image information. Also, in a situation in which scoring could occur but does not occur, the image information may be output by superimposing the image information on one area of the image information in a stationary state for a short period of time.

In this way, by distinguishing the types of sounds generated in different situations and providing the image information using different visual effects, it is possible to add more fun to the game viewing for users using the specific space. In addition, by adopting a method of providing image information suitable for a situation, it is possible to further enhance the effect of transmitting the image information.

Hereinafter, an embodiment related to a case in which the image information is output while moving on the image information will be described with reference to FIGS. 4A, 4B and 4C .

4A, 4B, and 4C are diagrams illustrating an embodiment in which image information overlaps while moving on the image information.

First, as in the first drawing of FIGS. 4A, 4B and 4C , image information 10 photographed for one area of the specific space may be output to the display unit 151 . The control unit 180 may determine whether the sound sensed in the specific space through the sensing unit satisfies a preset condition. When the sensed sound satisfies a preset condition, the controller 180 may variously control an output method of the image information based on the type of the sensed sound.

More specifically, the controller 180 may control the display unit 151 so that the image information overlaps while moving on the image information. In addition, the display unit 151 may be controlled to change the speed, direction, range, and transparency of the image information moving on the image information based on the type of the detected sound. Also, as described above, the type of the sound may be determined differently based on a size range in which the sound is sensed, a specific frequency region, a sensed time, and the like.

For example, referring to the second drawing of FIG. 4A , the controller 180 moves so that the image information 11 is gradually superimposed on the image information 10 from a downward direction of the display unit 151 . can do it Also, the image information 11 may be moved to overlap up to a preset range on the image information 10 as shown in the third diagram of FIG. 4A .

And, as shown in the fourth diagram of FIG. 4A , the image information 11 may move downward of the display unit 151 again after reaching a preset range of the image information 10 . That is, the image information 11 may be output in such a way that it starts to be output from a specific direction, reaches a specific range, and then returns to the surface on which the image information 11 was output.

On the contrary, as shown in the fourth diagram of FIG. 4B , the image information 11 may continuously move upward on the display unit 151 . That is, the output of the image information 11 may be controlled by a method of moving while maintaining the direction in which the image information was previously output and overlapping at least a portion of the image information 10 .

In this way, the controller 180 may control the moving direction differently in a state in which the image information is superimposed on the image information according to the type of the sensed sound. In addition, the controller 180 may control the speed at which the image information moves in an overlapping state on the image information to vary.

That is, referring to FIGS. 4A and 4C , the controller 180 can control the speed at which the image information 11 moves while being superimposed on the image information 10 based on the type of the detected sound. have. Therefore, as in FIG. 4C , the image information 11 reaches the preset range of the image information 10 more quickly, and then rapidly moves in the direction in which it was originally output, so that the output can be terminated. .

As such, when the image information overlaps while moving on the image information, the controller 180 may provide various visual effects by adjusting the direction and speed of the movement of the image information.

Meanwhile, the image information may be outputted for a preset time in a state of being still in one area of the image information.

5A, 5B, and 5C are diagrams illustrating different embodiments in which the image information is output while being superimposed on the image information in a static state.

The controller 180 may output the image information by superimposing it on at least a portion of the image information in a stationary state. In this case, the controller 180 may variously adjust the size, shape, position, transparency, etc. of the image information output on the image information based on the type of the detected sound.

That is, as shown in FIG. 5A , the controller 180 may control the display unit 151 to overlap the image information 11 on a preset region of the image information 10 in a stationary state. Also, as shown in FIG. 5B , the controller 180 may control the display unit 151 so that the image information 11 is superimposed on the image information 10 in a preset shape or shape.

As another example, as in 5c , the controller 180 may adjust the image information 11 to a preset transparency and output it to a preset area of the image information 10 . In this case, at least one region of the image information 10 may be covered by the output of the image information 11 .

In this way, the controller 180 may provide image information having different visual effects to the user based on various situations corresponding to the type of sound sensed in the specific space.

Meanwhile, while the image information is output on the image information, the controller 180 may control an output state of the image information according to an output method of the image information. In this regard, it will be described with reference to FIGS. 6A, 6B and 6C.

6A, 6B, and 6C are diagrams illustrating an embodiment in which the output of image information is controlled in different ways according to the output method of the image information.

The image information is image information photographed for one region of the specific space, and may include a plurality of consecutive images moving with the passage of time. The controller 180 may variously control the output of the image information by using an image related to a time point at which the image information is output on the image information among a plurality of images constituting the image information.

First, as shown in the second diagram of FIG. 6A , based on the detection of a sound corresponding to a preset condition in the specific space, the controller 180 outputs the image information 11 on the image information 10 . can do. In addition, the image information 11 may be output in a manner of moving in a specific direction in an overlapping state on the image information 10 , as in the third diagram of FIG. 6A .

In this case, the controller 180 may select an image corresponding to a time point at which the image information 11 is output on the image information 10 from among a plurality of images constituting the image information 10 . In addition, the output of the selected image may be maintained on the display unit 151 for a preset time during which the image information 11 is output on the image information 10 . That is, as in the second and third drawings of FIG. 6A , the output of the selected image may be maintained for a time during which the image information 11 is output.

Thereafter, when the output of the image information 11 is finished, the controller 180 displays the real-time recording screen 13 for one area of the specific space at the time when the output of the image information 11 is finished. It can output to the unit 151 .

Alternatively, the controller 180 may control the display unit 151 so that a continuous image corresponding to a preset section among the plurality of images is output together with the image information while the image information is output.

That is, referring to FIG. 6B , while the image information 11 is output, continuous images 10a and 10b corresponding to a preset section among the plurality of images may be output together with the image information 11 . have. In this case, the preset section may be determined to have a length corresponding to the time at which the image information 11 is output.

Also, when the output of the image information 11 is finished, the controller 180 may output the image 13 corresponding to the next sequence of the preset section to the display unit 151 . In addition, the controller 180 may output a real-time shooting screen for one area of the specific space to the display unit 151 at the time when the output of the image information 11 is finished.

As another example, when the image information is output while being superimposed on the image information in a static state, the controller 180 may output a preset section of the image information together with the image information. That is, as in the first and second drawings of FIG. 6C , the image information 11 may be output while being superimposed on at least one region of the image information 10 in a stationary state. Also, at least a portion 10a and 10b of the image information 10 may be output to the display unit 151 at a length corresponding to the time at which the image information 11 is output.

In this way, the controller 180 may differently adjust the output state of the image information according to a method in which the image information is output to the image information. That is, the output state of the image information may be adjusted according to whether the image information is output while moving on the image information or is output in a stationary state. Accordingly, the user can enjoy an interesting visual effect while being provided with the image information and the image information without being hindered by one piece of information from providing the other information.

The controller 180 may divide the display unit 151 and output the image information to one divided area. As such, when the display unit 151 is in a divided state, the output method of the image information may be different.

7A and 7B are diagrams illustrating an embodiment related to an output method of image information when image information is output to one region of the divided display unit.

The controller 180 may divide the display unit 151 into a plurality of regions, and output the image information and a plurality of screen information to each of the plurality of regions. Also, when the sound sensed in the specific space satisfies a preset condition, the controller 180 may output one of the plurality of screen information as the image information on the image information.

Also, the controller 180 may select one of the plurality of screen information as the image information based on the type of the detected sound. In addition, the display unit 151 may be controlled so that the one screen information is output on the image information from an area where one screen information selected as the image information is output. Accordingly, the output method of the image information may vary according to which screen information among the plurality of screen information is selected as the image information.

First, referring to FIG. 7A , the display unit 151 may be divided into three regions, and the image information 10 may be output to a region corresponding to the middle of the three regions. Also, screen information 14 and 15 may be output to the remaining two areas, respectively.

In this case, when the sensed sound corresponds to a preset condition, the controller 180 may output one of the screen information 14 and 15 as the image information on the image information 10 . More specifically, the controller 180 may select one 14 of the screen information 14 and 15 as the image information based on the type of the detected sound.

In addition, the controller 180 controls the screen information 14 in the direction in which the image information 10 is output from the area in which the one screen information 14 is output (the area corresponding to the left of the three areas). The display unit 151 may be controlled to be gradually enlarged.

Also, when the one screen information 14 is selected, the controller 180 may end the output of the remaining screen information 15 . In addition, the display unit 151 may be controlled so that the image information 10 is enlarged to a size corresponding to the entire area of the display unit 151 .

That is, as shown in the second diagram of FIG. 7A , the output of the remaining screen information 15 may be terminated, and the image information 10 may be output in a size corresponding to the entire area of the display unit 151 . Also, the one screen information 14 may be gradually enlarged from the left area among the three areas, and output so as to overlap at least a part of the enlarged image information 10 .

The one screen information 14 may be enlarged to overlap a preset range of the enlarged image information 10 as shown in the third diagram of FIG. 7A . And, when the preset range is reached, the controller 180 ends the output of the one screen information 14 and returns to the output state before the one screen information 14 is selected. The display unit 151 may be controlled.

Accordingly, as shown in the fourth diagram of FIG. 7A , the display unit 151 may be divided into a plurality of regions and return to a state in which image information and a plurality of screen information are output to each region. At this time, the controller 180 may output the real-time photographed screen 13 for one area of the specific space corresponding to the time when the output of the one screen information 14 is finished to the divided one area. have.

Alternatively, the controller 180 may differently determine screen information selected as the image information based on the type of the detected sound. That is, as in FIG. 7B , screen information 15 different from that of FIG. 7A among the plurality of screen information 14 and 15 may be selected as the image information. The other screen information 15 may be output to overlap at least a portion of the image information 10 while gradually expanding from an area (right area) where the other screen information 15 is output.

In addition, when the plurality of screen information is selected as image information and overlapped on the image information, the controller 180 may adjust the transparency of the screen information selected as the image information so that viewing of the image information is not disturbed. .

As such, when the display unit disposed in the specific space is formed to have a size greater than or equal to a preset size, various visual information may be provided at once through the division of the display unit. In addition, according to various situations corresponding to each type of sensed sound, information may be transmitted in a way that the visual information output to each of the divided regions can be effectively recognized by the user.

The digital signage according to the present invention may include a wireless communication unit, and may perform wireless communication with an external device located in a specific area through the wireless communication unit. More specifically, the digital signage that can be applied to the specific space divides the specific space into a plurality of areas, and includes a location information module capable of performing wireless communication with the external device in each of the plurality of areas. can Through this, detailed location information of the external device located in the specific space can be identified, and information related to the visual information output to the display unit can be transmitted and received to the external device. decide to do

8A and 8B are diagrams illustrating an embodiment of providing visual information output to a display unit to an external device through wireless communication with the external device.
