Patent Application
20170287005
The various embodiments described herein pertain generally to a method and system for managing an authority to control a digital signage, and, also relates to a non-transitory computer-readable recording medium therefor.
Recently, the form of media which provide contents is diversified and the way to provide the contents is automated. In an outdoor advertisement, for example, a modern method of providing advertisement contents through a flexible medium such as a LED display or a LCD TV is introduced, beyond a typical method of providing advertisement contents through a stationary printed medium such as papers or films.
A so-called digital signage is a communication tool which an advertiser uses for marketing, advertisement, training, and so forth and through which a customer experience can be induced. Specifically, a digital signage refers to a digital imaging device configured to provide advertisement contents intended by the advertiser as well as typical broadcasting contents in a public place such as an airport, a hotel, a hospital, and so forth. The digital signage is also called a DID (Digital Information Display). Since the digital signage is equipped with a processor and a memory therein and is capable of displaying various types of contents vividly while being portable as well, it has a wide range of applications to marketing, customer services, information systems, etc., in public places such as department stores, subways, bus stops, and so forth. Further, not only the advertisement contents are provided through the digital signage, but various kinds of contents having various other purposes than the advertisement are also provided through the digital signage.
Recently, as the function of the digital signage is diversified and its utilization is wide-spread, there has been introduced a technology of supporting a user to control at least a partial function of the digital signage by using a typical user device such as his/her own smart phone, thus enabling interaction between the user and the digital signage. That is, the user is allowed to interact with the digital signage by using the user device, and is thus capable of gaining required information actively on his/her own or can be given a new user experience.
Since, however, the digital signage is generally installed in a place which may be exposed to many unspecified people, there arises a demand for a technology capable of managing a control authority over the digital signage between a multiple number of user devices.
Example embodiments of the present disclosure are conceived to meet the aforementioned requirements.
The example embodiments provide a technology of adaptively managing a control authority over a digital signage between a plurality of user devices by, if a search request for a digital signage is received from a first user device, providing, to the first user device, information upon at least one digital signage over which the first user device is capable of making a request to have a control authority; and if a request for a control authority over a first digital signage is received from the first user device, determining the control authority over the first digital signage to be assigned to the first user device with reference to context information regarding at least one of the first user device, a user account related to the first user device and the first digital signage.

If a request for a control authority over a first digital signage 410 is received from a first user device 310, the management system 200 determines a control authority over the first digital signage 410 to be assigned to the first user device 310 while referring to context information regarding the first user device 310, a user account related to the first user device 310 or the first digital signage 410.
The configuration and the operation of the management system 200 according to the example embodiment will be further elaborated later. Here, it should be noted that the above description of the management system 200 is nothing more than an example, and it is clearly understood by those skilled in the art that at least a part of functions or constituent components of the management system 200 may be embodied within the user device 300 or the digital signage 400, or included in the user device 300 or the digital signage 400 when necessary.
The user device 300 according to the example embodiment is a digital device having a function of allowing a user to access and communicate with the management system 200 or the digital signage 400. The use device 300 is not particularly limited as long as it is implemented by a digital device equipped with a memory and a microprocessor and thus has an operation ability. By way of non-limiting example, a smart phone, a tablet, a desktop computer, a laptop computer, a workstation, a PDA, a web pad, a mobile phone, or the like may be used as the user device 300.
Further, according to the example embodiment, the user device 300 is capable of performing a function of accessing the digital signage 400 over which it has a control authority and controlling at least a partial function of the digital signage 400, thus supporting the user to utilize the digital signage 400 actively. In the example embodiment, the digital device 300 may include an application (not shown) which performs the above-described function of the use device. This application may be downloaded from the management system 200 or a commonly known web server (not shown). Meanwhile, characteristics of such a program module may be substantially similar to those of an interfacing unit 210, a control authority managing unit 220, a communication unit 230 and a control unit 240 of the management system 200 to be described later. Here, at least a part of the application may be replaced by a hardware device or a firmware device capable of performing substantially the same or equivalent function as that of the application, when necessary.
According to the example embodiment, the digital signage 400 is capable of performing a function of providing an application or contents provided from the management system 200 to people around the digital signage 400. Further, according to the example embodiment, when performing at least a part of its function, the digital signage 400 is capable of interacting with the digital device 300 which is assigned the control authority over the digital signage 400.

Further, according to the example embodiment, the digital signage 400 may be installed in public places such as a department store, a subway, a bus stop, an air port, a hotel, a hospital, and so forth. However, it should be noted that these installation places are just examples, and the place where the digital signage 400 is installed is not limited to the aforementioned examples.
Meanwhile, a process in which a user uses the digital signage 400 according to the example embodiment will be schematically described later.
Configuration of Management System
Now, an internal configuration of the management system 200 and functions of individual components thereof will be explained according to the example embodiment.
As illustrated in
According to the example embodiment, if a search request for the digital signage 400 is received from the first user device 310, the interfacing unit 210 searches for one or more digital signages 410 and 420 over which the first user device 310 can make a request to have a control authority (that is, which can be connected with the first user device 310). Then, the interfacing unit 210 provides the first device 310 with information upon the retrieved one or more digital signages 410 and 420.
Here, according to the example embodiment, the one or more digital signages over which the user device 300 can make the request to have the control authority may be the digital signages 410 and 420 which exist within a preset distance from the user device 310 and can be connected with the first user device 310 through the wired or wireless communications network 100.
Further, according to the example embodiment, the interfacing unit 210 is capable of performing a function receiving a request for a control authority over the first digital signage 410 (or the second digital signage 420) from the first user device 310. Here, the first digital signage 410 may be a digital signage selected by the first user device.
According to the example embodiment, if the request for demanding the control authority over the first digital signage 410 is received from the first user device 310, the control authority managing unit 220 determines a control authority over the first digital signage 410 to be assigned to the first user device 310 while referring to context information regarding at least one of the first user device 310, a user account related to the first user device 310 and the first digital signage 410.
Furthermore, according to the example embodiment, if a request for demanding a control authority over the first digital signage 410 is received from the second user device 320, the control authority managing unit 220 determines a control authority over the first digital signage 410 to be assigned to the second user device 320 while referring to context information regarding at least one of the second user device 320, a user account related to the second use device 320 and the first digital signage 410 as well as information upon the control authority over the first digital signage 410 already assigned to the first user device 310. Here, according to the exemplary embodiment, the control authority over the first digital signage 410 assigned to the first user device 310 and the control authority over the first digital signage 410 assigned to the second user device 320 may be determined not to collide with or be overlapped with each other.
Moreover, according to the example embodiment, if a control authority over a certain digital signage is assigned to a certain digital device, the control authority managing unit 220 may also assign this digital device a control authority over another digital signage which belongs to the same group as the certain digital group. By way of example, the third user device 330 assigned a control authority over the second digital signage 420 may also be assigned a control authority over a third digital signage 430 belonging to the same group 400A as the second digital signage 420.
Here, according to the example embodiment, the control authority over the first digital signage 410 to be assigned to the first user device 310 may specify a time during which the first user device 310 is capable of controlling the first digital signage 410, a scope of applications controllable by the first user device 310 among the applications executed in the first digital signage 410, a scope of contents controllable by the first user device 310 among the contents provided by the first digital signage 410, a scope of another digital signage 420 controllable by the first user device 310 among the another digital signages 420 connected to the first digital signage 410, and the like.
To elaborate, according to the example embodiment, the context information regarding the first user device 310 which can be a reference in determining the control authority may include information upon, for example, specifications, performance and location of the first user device. By way of example, the control authority managing unit 220 according to the example embodiment may assign the first user device 310 an authority for controlling a keyboard input function of the digital signage 410 by referring to context information that the first user device 310 which has made a request for the control authority over the first digital signage 410 is equipped with a keyboard input device.
Furthermore, according to the example embodiment, the context information regarding the user account related to the first user device 310 which can be a reference in determining the control authority may include information upon an authority possessed by the user account, demographic information of the user, etc. For example, the control authority managing unit 220 according to the example embodiment may assign the first user device 310 an authority allowing the first user device 310 to access, among the contents provided by the first digital signage 410, contents except those for adults only.
In addition, according to the example embodiment, the context information upon the first digital signage 410 that can be a reference in determining the control authority may include the number of other user devices 320, 330 and 340 which are given control authorities over the first digital signage 410, the number of other user devices 320, 330 and 340 capable of making a request to possess a control authority over the first digital signage 410, the number of other user devices 320, 330, 340 which exist within a preset distance from the first digital signage 410, and so forth. For example, with the rise of the number of the other user devices 320, 330 and 340 having the control authority over the first digital signage 410, the control authority managing unit 220 may shorten the time during which the first user device 310 is capable of controlling the first digital signage 410.
Moreover, according to the example embodiment, the control authority managing unit 220 may modify control authorities over the digital signages 410 to 430 assigned to the user devices 310 to 340 dynamically as the context information changes. For example, in case that previously assigned control authorities need to be adjusted because the number of user devices which have made a request for a control authority over the first digital signage 410 exceeds a preset number, the authority control managing unit 220 may deprive at least one user device (for instance, a user device which has possessed a control authority over the first digital signage 410 for the longest duration) of the control authority over the first digital signage 410.
Meanwhile, according to the example embodiment, if the control authority over the first digital signage is given to the first user device 310, the control authority managing unit 220 may allow control commands received from the user device 310 to be transmitted to the first digital signage 410 by being encoded according to a predetermined algorithm. By way of example, data transceived between the first user device and the first digital signage may be encoded according to a RSA encoding algorithm, so that the digital signage 400 is prevented from being controlled by an unauthorized user device (not shown). Thus, leakage of private information of the user through the digital signage 400 which can be shared by the plurality of user devices 300 can be avoided.
According to the example embodiment, the communication unit 230 is configured to perform a function of enabling transmission/reception of data from/to the management system 200.
The control unit 240 according to the example embodiment may perform a function of controlling a data flow between the interfacing unit 210, the control authority managing unit 220 and the communication unit 230. That is, the control unit 240 according to the example embodiment is capable of controlling the interfacing unit 210, the control authority managing unit 220 and the communication unit 230 to perform their own functions by controlling a data flow from/to the outside of the management system 200 and a data flow between the individual components of the management system 200.
So far, the example embodiment has been described for the case where the target of control which is controllable by the user device is a digital signage. However, the present disclosure is not limited to the above-described example embodiment. For example, according to another example embodiment, any of various devices can be a target of control method of the present disclosure as long s the devices are equipped with a memory and a microprocessor and thus has an operation ability. By way of non-limiting example, a smart phone, a tablet, a desktop computer, a laptop computer, a workstation, a wearable device, other IoT (Internet of Things) devices (including watches, cars, and household appliances such as refrigerators, washing machines, boilers, air conditions, etc.). A management system 200 according to another example embodiment may be configured to assign a control authority over the various devices as mentioned above to at least one user device.
