The present invention relates to a tiled display system, and more particularly, to an event-based user interaction providing apparatus for providing user interaction by generalizing a plurality of user input signals received from a multi-user input apparatus in the form of an event, And a method of using the same.

As the display technology has been developed recently, the use of displays is expanding in various fields such as smart phones, tablet PCs, and other user terminals becoming popular, and outdoor digital advertising being expanded. Accordingly, in order to construct a large-sized display device that provides good quality information to a large number of users, a tiled display system that forms a single screen with a plurality of display panels is mainly utilized.

The tiled display system allows the user to move the body directly in front of the display or to control the tiled display using user input devices such as laser pointers, mobile devices, three-dimensional gyro mice and multi-touch screens.

In particular, since tiled displays can be utilized in various applications such as virtual reality, games, and digital advertisements, user interaction is required to naturally control tiled displays using a multi-user input device.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an operation environment of an event-based user interaction providing apparatus and a method using the same according to an embodiment of the present invention.

Referring to FIG. 1, an event-based user interaction providing apparatus and a method using the same may be implemented by a tiled display system 10 that forms a single screen with a plurality of display panels 11.

Here, the tiled display system 10 includes a plurality of display panels 11 as D 11 , D 12 , D 13 , D 14 ... ... D mn in the form of a matrix to form a large display.

The display panel 11 may be a PDP (Plasma Display Panel), a Liquid Crystal Display (LCD), a Thin Film Transistor LCD (TFT-LCD), or the like capable of displaying various information such as an image or an image. But are not limited to, flat panel display devices such as LEDs (Light Emitting Diodes), OLEDs (Organic LEDs), Retina Displays, and Dynamic Scattering Display Panels.

Since the tiled display system 10 can be utilized in various applications such as a virtual reality, a game, or a digital advertisement, in order to control the tiled display system 10 using various user input devices 20, Action is required.

Accordingly, the tiled display system 10 and the user input device 20 can be connected to a network such as a cable, a universal serial bus (USB), a Bluetooth, a wireless fidelity (WiFi), a 3G (3G) And the like, to provide user interaction by exchanging user input signals through various communication interfaces.

Here, the user input device 20 may be an input device such as a motion recognition sensor such as a Kinect camera, a laser pointer, a three-dimensional gyro mouse, a keyboard or a controller, a smart phone, a tablet PC, a PDA (Personal digital assistant), a notebook computer, a computer, and the like. However, the present invention is not limited thereto, and may be applied to various devices capable of controlling a tiled display by generating a plurality of user input signals .

In particular, the present invention proposes to generalize a user input signal so that a plurality of users can efficiently interact with each other using the multi-user input device 20 in the tiled display system 10. Here, the generalization of the user input signal may mean a process for using at least one user input signal generated in response to a user's request in the multi-user input device 20 in a universal manner. Therefore, in order to universally use a user input signal, the following requirement must be satisfied.

First, the user input signal should not be lost so that the utilization range of the user input device 20 is not reduced. Second, the user input signal should be generalized so that it can be applied to various types of tiled display application programs. Thirdly, the user input signal should not be too crowded or inconvenient to use by overly subdividing or simplifying the user input signal. Fourth, user input signals should be generalized based on easily understandable concepts.

The user input device 20 can be generalized and processed according to a common method. Therefore, regardless of the type and number of the user input device 20, Performance can be improved. In addition, it is possible to provide reliable user interaction according to a multi-user input device.

FIG. 2 is a block diagram illustrating an event-based user interaction providing apparatus according to an embodiment of the present invention. FIG. 3 is a block diagram illustrating an event generating unit and an event processing unit of the apparatus for providing a user interaction according to an embodiment of the present invention. .

Referring to FIGS. 2 and 3, the event-based user interaction providing apparatus 100 may include at least one event generating unit 110 and an event processing unit 120. In addition, an event providing unit 130 may be further included.

The event-based user interaction providing apparatus 100 may be implemented by a tiled display system 10 that constitutes a single screen with a plurality of display panels 11 and may include a plurality of user input signals The tiled display can be controlled by processing in the form of an event.

The event generating unit 110 may generate an event by generalizing at least one user input signal received from the user input device 20 based on interdependencies or progress of user input signals.

Here, the one event generating unit 110 is 1: 1 mapped to one user input device 20 and receives at least one user input signal generated from the user input device 20 according to a user's request .

At this time, at least one user input signal may be received in various ways depending on the type and characteristics of the user input device 20. [ For example, when using a user input device 20 such as a keyboard or a mouse, an event generated by a user's operation may be received as a user input signal through a system message of the operating system.

In addition, when a user input device 20 such as a Kinect camera or an information processing terminal is used, at least one user input signal can be obtained from the device driver. In addition, when there is a separate relay apparatus for relaying the user input apparatus 20 and the event generation unit 110, a user input signal may be received from the relay apparatus.

Since the value, type, property, or reception method of the user input signal differs according to the user input device 20, it is necessary to generalize the user input signal in order to process it in a common method.

Thus, the event generation unit 110 may include an input signal classification module 111 and an event generation module 113, as shown in FIG.

The input signal classification module 111 analyzes at least one user input signal based on the interdependency between user input signals, classifies the user input signal independently performed as an independent signal, and outputs the dependent user input signal as a slave signal Can be classified.

Also, status information can be added to a user input signal that is continuously performed for a predetermined period of time by confirming a progress status such as start or end of a user input signal classified as an independent signal or a slave signal.

More specifically, it is possible to determine interdependency between user input signals and classify at least one user input signal that exists independently without affecting other user input signals into independent signals. Alternatively, A user input signal which can be determined or influenced can be classified as a slave signal. However, the present invention is not limited to this, and it is possible to classify a user input signal by applying a different method to a user input signal that is difficult to determine interdependency between user input signals or has a different classification criterion.

Thus, the event generation module 113 may generate an event by generalizing at least one user input signal based on at least one of an independent signal, a dependent signal, and status information.

The at least one user input signal may be generalized using the event so that the user input signal can be applied to all the tiled display application programs without being lost. Also, by classifying the user input signals based on the interdependency between the user input signals, the user input signals are not excessively simplified or refined, and can be easily understood by using existing events.

The event processing unit 120 can identify and process events received by at least one event generating unit 110 for each user input device 20. [ That is, the event processing unit 120 may include an event identification module 121 and an event processing module 123, as shown in FIG.

The event identification module 121 may identify the event by the user input device 20 by adding the identification information of the user input device 20 to the event generated by the at least one event generation unit 110. [

Here, the reason for identifying the event for each user input device 20 is that the user may be given the right to use the tiled display application program at the same time, so that interference may occur.

Therefore, it is possible to prevent interference by sharing the usage right information such as the order of use or the use time of the user input device 20 with respect to the tiled display application program in each user input device 20. [

However, according to the state of the tiled display application program, there is a difference in the processing method of the event, so that a mismatch of the user interaction may occur. Thus, if the user input device 20 is recognized as not operating or is serious, malfunction of the tiled display application program may occur.

Accordingly, the state information for the tiled display application program can also be shared by the multi-user input device 20, thereby preventing inconsistency in user interaction.

The event processing module 123 can process events based on usage right information for the tiled display application program shared by the user input device 20 or status information about the tiled display application program.

In other words, it is possible to prevent the occurrence of interference by granting a usage right to the user input device 20 and protecting the exclusive right based on usage right information such as a usage order or usage time for the tiled display application program. In addition, it is possible to prevent the inconsistency of the interaction by processing the event according to the state of the tiled display application program.

The interaction providing unit 130 may provide the user interaction by applying the event processed by the event processing unit 120 to the tiled display application program.

4 is an exemplary diagram illustrating user interaction using a multi-user input device in accordance with an embodiment of the present invention.

Referring to FIG. 4, a screen displayed on the tiled display can be controlled by using a plurality of keyboard cameras 12 arranged in the tiled display system 10 and a mouse 13 connected by various communication interfaces.

A plurality of Kinect cameras 12 arranged in the tiled display system 10 can recognize a user's pose or gesture. Thus, user input signals such as information about the user's pose, three-dimensional coordinates of the user's skeleton can be generated.

The mouse 13 also displays information on the type of the mouse button clicked, information on whether or not the mouse is clicked, information on the mouse wheel operation, ) May be generated in the form of an event.

Since the types of the user input device 20 for the plurality of Kinect cameras 12 and the mouse 13 are different and the types of the user input signals generated thereby are different, in order to process them in a common method, It is necessary to generalize the signal.

Accordingly, at least one user input signal received from the Kinect camera 12 and at least one user input signal received from the mouse 13 are generalized based on the interdependency or progress of the user input signal to generate an event .

More specifically, it is possible to classify the user input signal by determining the interdependence of the user input signal received from the Kinect camera 12. For example, information about a user's pose that can operate independently without affecting other user input signals may be classified as an independent signal, and information about the skeleton of a user that can determine or affect the content of another user input signal The three-dimensional coordinate can be classified as a slave signal.

The event can be generated by using the Kinect camera 12 by adding the state information to the user input signal continuously performed for a predetermined time by confirming the progress of the independent signal and the slave signal classified as described above.

Similarly, information on the type of the mouse button that is clicked in the user input signal received from the mouse 13 can be classified as an independent signal, and information about the presence or absence of a mouse click, information about the mouse wheel operation, the position information of the point can be classified as a slave signal. Here, the state information may be added based on the progress state of the user input signal, so that an event according to the use of the mouse 13 may be generated.

At this time, in order to identify whether the event is generalized based on a user input signal received from any one of the Kinect camera 12 and the mouse 13, identification information on the user input device 20 Can be added. Here, the Kinect camera 12 and the mouse 13 may share usage right information for the tiled display application program or status information about the tiled display application program.

Therefore, an event according to the use of the Kinect camera 12 or an event according to the use of the mouse 13 can be processed on the basis of the usage right information such as the order or use time of the tiled display application program. If the Kinect camera 12 has usage rights, it can prevent interference by protecting its exclusive right. Also, in processing an event according to the use of the Kinect camera 12, it is possible to prevent an inconsistency of the interaction by processing an event according to the state of the tiled display application program.

Therefore, by using the above-described method, it is possible to provide user interaction so as to efficiently control the tiled display to a plurality of users using the plurality of Kinect cameras 12 and the mouse 13. [

Herein, the user interaction is provided using the Kinect camera 12 and the mouse 13. However, the present invention is not limited to this, but may be applied to the various user input devices 20, It will be able to provide reliable user interaction.

5 is a flowchart illustrating an event-based user interaction providing method according to an embodiment of the present invention.

Referring to FIG. 5, a method for providing an event-based user interaction includes generating an event by generalizing at least one user input signal (S100), and processing the event for each user input device (S200) . The method may further include applying the processed event to the tiled display application program to provide user interaction (S300).

The event-based user interaction providing method may be performed by a user interaction providing apparatus. Here, the user interaction providing apparatus 100 may be implemented by a tiled display system 10 that constitutes a single screen with a plurality of display panels 11, An event processing unit 120 for identifying and processing an event for each user input device 20 and an interaction providing unit 120 for applying the processed event to a tiled display application program 130 to provide user interaction.

First, at least one user input signal may be received from the user input device 20. At this time, at least one user input signal may be received in various ways depending on the type and characteristics of the user input device 20. [ For example, when using a user input device 20 such as a keyboard or a mouse, an event generated by a user's operation can be acquired as a user input signal through a system message.

In addition, when a user input device 20 such as a Kinect camera or an information processing terminal is used, at least one user input signal can be obtained from the device driver. In addition, when there is a separate relay apparatus for relaying the user input apparatus 20 and the event generation unit 110, a user input signal may be received from the relay apparatus.

Since the value, type, or property of the user input signal may differ depending on the type, characteristics, and reception method of the user input device 20, it is necessary to generalize the user input signal in order to process it in a common method.

Thus, at least one user input signal may be generalized based on the interdependency or progress of user input signals to generate an event (SlOO).

That is, the at least one user input signal may be analyzed based on the interdependency between the user input signals to classify the user input signal, which is performed independently, into the independent signal and classify the user input signal that is performed depending on the user input signal as the dependent signal.

For example, the interdependence between user input signals may be determined so that at least one user input signal that exists independently without affecting other user input signals may be classified as an independent signal. Alternatively, A user input signal which can be determined or influenced can be classified as a slave signal. However, the present invention is not limited to this, and it is possible to classify user input signals by applying a different method to user input signals that are difficult to determine interdependency between user input signals or have separate classification criteria.

The state information can be added to the user input signal continuously performed for a predetermined period of time by confirming the progress of the user input signal classified into the independent signal or the slave signal.

In this manner, an event can be generated by generalizing at least one user input signal based on at least one of an independent signal, a slave signal, and status information (S100).

The identification information for the user input device 20 may be added to the event to identify the event for each user input device 20 (S200). At this time, the reason for identifying the event for each user input device 20 is that the use right for the tiled display application program is given to the multi-user input device 20 at the same time, so that interference may occur.

Therefore, the multi-user input device 20 can prevent the interference by sharing the usage right information such as the usage order or the use time of the tiled display application program of the user input device 20.

However, according to the state of the tiled display application program, there is a difference in the processing method of the event, so that a mismatch of the user interaction may occur. Thus, if the user input device 20 is recognized as not operating or is serious, malfunction of the tiled display application program may occur. Accordingly, it is possible to prevent the inconsistency of the user interaction by sharing the state information on the tiled display application program in the multi-user input device 20. [

The user can process the event on the basis of the usage right information for the tiled display application program shared by the user input device 20 or the status information about the tiled display application program (S200).

More specifically, the user authority is given to the user input device 20 in accordance with the usage right information such as the order of use or the use time of the tiled display application program, and the exclusive right is protected to prevent interference with the interaction . In addition, it is possible to prevent the inconsistency of the interaction by processing the event according to the state of the tiled display application program.

By applying the processed event to the tiled display application program in this way, the user interaction can be provided (S300).

According to the event-based user interaction providing apparatus and the method of using the same according to the embodiment of the present invention, user input signals according to the multi-user input apparatus are generalized and processed in a common method, Regardless of the number, it is possible to improve the performance of user interaction efficiently.

User input device, it is possible to provide a reliable user interaction according to a multi-user input device by solving the problem of interference or inconsistency with respect to user interaction.
