2. The terminal used by the offline game participant may be basically equipped with a GPS module, an e-compass, an accelerometer, 3G (VoIP), WiFi, and Bluetooth.

3. In online / offline ubiquitous games, each team may consist of at least two players, and each team may consist of at least two teams.

4. Each team may include at least one online game participant connected to the Internet by wire and at least one smartphone game participant in the actual game area offline.

5. A terminal used by a smartphone game participant periodically transmits its location measured from GPS through a game S / W (ie, a game application downloaded from the game server) to a central game server through a wireless communication network. The online game participant can read the current location of smartphone game participants from a central game server and monitor them on a digital map of the game area.

6. Online game participants generally cannot directly monitor the opponent's smartphone game participant's location, but they can monitor the smartphone game participant of the other team's smartphone game participant within a certain distance.

7. The online game participant texts directly to the smartphone user of the same team without going through the central game server. (Team B smartphone game participant in FIG. You can make a voice call over VoIP or via VoIP.

8. The actual game scenario can be set and changed by software. Therefore, the game content may be generated or updated in the game server according to the input scenario, and the online game participant and the smartphone game participant may proceed with the game according to the game scenario.

9. In the game scenario, the smartphone game participant moves to a specific object, building, road, and terrain to perform a given task, and receives augmented reality information provided by an environment-specific additional information server installed at a specific location to identify a specific situation. And cooperate with other game participants (online game participants and other smartphone game participants) of the same team.

10. Players of opposing teams may also be assigned tasks corresponding to the tasks performed by other teams, depending on the game scenario.

11. Each team's mission may be received from the game server via a wireless communication network, but only one fragmentary command is given at a time, and the specific mission may be directed to a particular area and sent by an environment-specific additional information server installed in that area. Received through augmented reality information.

12. After the smartphone game participant moves to a specific area and performs a mission according to a given mission, the smartphone game participant's terminal uses GPS to coordinate its coordinates with a central game server through a wireless communication network such as 3G or WiFi. You can register at

13. Subsequently, the smartphone game participant can read the information from the local embedded information server installed in the area through short-range wireless communication technology such as IEEE802.15, Direct WiFi, etc. in the area, and receive a new mission again. .

14. At this time, when the smartphone game participant illuminates a specific street or building using a camera mounted on his terminal at the local location, the terminal uses a GPS module, an electronic compass, an accelerometer, etc. in the corresponding direction, The terminal may recognize the location and the object, and accordingly, the terminal may display the augmented reality information related to the corresponding direction, the location, the object, and the like transmitted from the environment-specific additional information server through the screen.

15. The task given by the central game server may be, for example, to find a real person or object in a particular area and move it to another safe place, or a smartphone game participant via an augmented screen from an embedded environment information server. It can be a quiz. Or, depending on the game scenario, the smartphone game participant may kill the smartphone game participant of the opposing team and remove it from the game. This is achieved through the action of applications in the game by connecting P-to-P to smartphone game participants directly via Bluetooth or WiFi. Of course, there can be a wide variety of game scenarios as well.

16. For example, as another application, a disability helper service using the present invention can be considered. In other words, the disabled select their own services and register them in the central server in advance, and volunteers who want to participate in the service select the available services and register them in the server. When a disabled person requests a service through a smartphone terminal at a specific time and a specific location, the game is started through a central game server, and a message is delivered to the smartphones of volunteers who can use the service based on the current location of the disabled person. . And the volunteers who accepted the first request will participate in the game and provide the service.

That is, according to the present invention, a smart phone game participant moving in the real world can measure his / her position and various measured using a GPS, an e-compass, an accelerometer, etc. provided by a smart phone terminal. The movement is periodically registered with a central game server on the Internet via wireless communication networks such as 3G and WiFi. In addition, the online game participant through the computer screen allows the smartphone game participant to regard the game participant as if the character exists online in the 'digital game map' space modeling the actual space where the smartphone game participant exists. will be.

Accordingly, the online and offline ubiquitous game implementation method and system according to the embodiment of the present invention have the following features.

[How to use the location information of smartphone game participants in the game]

Existing GPS navigation device shows the measured position coordinates on the map screen of the terminal, but in the present invention periodically registers the position coordinates of the smartphone game participants (that is, the terminal position coordinates) to the game server, the game The server pushes (broadcasts) the position coordinates of each smartphone participant to another authorized game participant (ie, the same team online game participant or / and other offline game participant, hereinafter referred to as "online game participant", etc.) terminal. to provide.

Therefore, the online game participant can monitor the position of the smartphone game participant of the same team in real time.

In addition, the game server compares the position coordinates of the smartphone game participants of the opposing team with the position coordinates of the smartphone game participants of the team, and when they come within a certain distance, the game servers display the position coordinates of each other to the team game participants. Show it on the screen and don't show it again if you move away.

[Game progress through environment-specific additional information server]

In order to provide augmented reality information and location-based services to specific objects, buildings, roads, and terrain in a real space, an environmentally embedded additional information server is installed. Participants of the smart phone may access the environment-specific additional information server using a short range wireless communication method such as Bluetooth, or direct WiFi, and receive location-based services or receive additional information for game progress.

In addition, a central game server or a local administrator can modify and update the contents of an embedded internal information server online through the Internet. The environment-specific additional information server is a ubiquitous micro server that is physically inserted into specific objects, buildings, roads, and terrain, and the game application agent on the smartphone terminal mediates communication with the environment-specific additional information server. Specific augmented reality information can be received from the additional information server, the augmented reality information received in this way is augmented reality terminal through the augmented reality application (which may be installed separately in the terminal or the game application) It can be implemented through the display screen of.

 In general, when a smartphone game participant approaches a specific physical location in the real world, a game application agent on the smartphone terminal communicates directly with the central game server via 3G or WiFi, which is necessary for the current mission of the game or the next step. The method of receiving information and requirements and augmenting and informing the smartphone screen may be used. However, newly added in an embodiment of the present invention, when a smartphone game participant approaches a specific physical location (that is, the location where the environment-specific additional information server is installed), short-range wireless such as Bluetooth or Direct WiFi The next step of the game is made by accessing the additional information server embedded in the environment using communication or the like, receiving augmented reality information, or performing location-based local operation.

In this case, in the environment embedded additional information server installed at various places in the real world, information necessary in the game initialization step may be preset according to the game scenario of the central game server. In addition, for real-time information exchange, the parameters and corresponding information are periodically synchronized between the game server and the environment-specific additional information servers in each region.

The following shows an example of a process in which a game is progressed based on information obtained through an environment-specific additional information server. First, when a smartphone game participant approaches a specific place in the real world, the smartphone game participant attempts to interconnect the environment-specific additional information server based on its location coordinate. At this time, if the connection fails, the central game server can be connected. Subsequently, after accessing the server and registering its own location coordinates, the corresponding information or mission of the game scenario is given according to the corresponding location coordinates, and the game of the next stage proceeds according to the given information or mission.

As such, the method of using the environment-specific additional information server may have the following advantages.

That is, in the present invention, additional information (for example, the task of the current game stage, information for guiding the next game stage, augmented reality information related thereto, etc.) for the game progress to the smartphone user participating in the online / offline omnipresent game In order to provide the additional information is not stored in the smartphone in advance, or using the additional information transmitted in real time from the game server. In other words, in the present invention, the additional information required by using an embedded environment information server (equipped with a near field communication function of IEEE 802.15 series such as Bluetooth) pre-installed at a specific location (object, building, road, and terrain) of the region. Use a method of conveying information. Therefore, using such a method, in order to transmit additional information for game progression to the smartphone, it is possible to reduce the cost of the smartphone periodically connected to wireless communication networks such as 3G and WiFi. At this time, the central game server can periodically manage the environment-intrinsic additional information server from a remote location, to update the latest information in real time.

[Features on Augmented Reality Implementation Method]

Augmented reality is a technology that has been recently adopted in many applications of the smart phone, the way to implement this is to use a specific mark for implementing augmented reality attached to buildings, etc. As a method of realizing the reality, augmented reality related to a corresponding position, place, and direction through analysis of an image acquired through a camera, and augmented reality is implemented based on information such as the position and direction of the terminal. There is a way.

Therefore, a method of providing specific game information (additional multimedia information such as text, graphics, video, etc.) to an offline game participant using augmented reality, and recognizing the image of the camera and providing the information, and terminal location information Both methods of providing information may be used.

As the former method, a method of using an image of a camera is, firstly, when a camera photographs an object, a building, and a terrain around it, software in a smartphone operates to recognize an object, and superimposes additional information prepared on the screen. Secondly, when the video captured by the smartphone is transmitted to the game server through a wireless communication network, the game server performs image recognition and retransmits additional information (various game information, etc.) to the smartphone. Can be.

However, when the video recognition and additional information processing inside the smartphone, the cost of using a wireless communication network is saved, but it puts a lot of burden on the memory or CPU inside the smartphone. On the other hand, when significant computation is required to recognize a complex image, it is difficult to process in a smartphone. Therefore, when the amount of augmented reality information to be provided on the smartphone screen or the content of the additional information changes over time, it is more efficient to use a game server via a wireless communication network. However, even in such a method, there is a problem in that the cost of using the wireless communication network is greatly increased, and the user response speed may decrease due to communication delay.

Therefore, an embodiment of the present invention uses a method of using location information as a method of implementing augmented reality. That is, in the embodiment of the present invention, the position of the smartphone using a GPS module mounted in the smartphone, an electronic compass for measuring a direction, a tilt measuring sensor (for example, a gravity sensor, an accelerometer, a gyro sensor, etc.), The way the smartphone is facing, the angle of inclination, etc. are used. At this time, the information about the terrain in the direction that the smartphone is directed may be stored in the smartphone in a limited situation, but most of the information is a lot because this is not a suitable way. Therefore, in the embodiment of the present invention, the location information or the like is transmitted to the game server or the environment-specific additional information server, and the server having received the location information or the like grasps the building and the additional information in the corresponding direction and returns it to the smartphone. Use the transmission method. In this case, various methods may be used.

That is, the smart phone directly transmits the location information to the game server and directly receives additional information for implementing augmented reality from the game server, and transmits the location information to the environment-specific additional information server through short-range wireless communication. There may be a method of receiving additional information from the additional information server, in reality, a subject holding the additional information is a game server, but a method of receiving the additional information through an environment-intrinsic additional information server.

Here, according to the preferred embodiment of the present invention, the smart phone may use a method (that is, the second method) in which additional information is transmitted through the short-range wireless communication between the environment-specific additional information server.

[Controlling Position and Posture of Smartphone]

Participants in smartphone games continue to interact with local environmental information servers through short-range wireless communication in order to verify that the screen they are currently projecting is the correct target indicator they are looking for. Accordingly, the smartphone game participant can continuously correct the position of the object to be captured by the camera by the message augmented on the smartphone screen from the additional information server.

In detail, first, the GPS is read to determine the current coordinates, and the direction and the tilt angle are measured using an electronic compass and an accelerometer. Second, the environment-specific additional information server receives this information and predicts what image is currently displayed on the smartphone screen, and the game participant moves the smartphone up, down, left and right or changes the angle to accurately focus on the target indicator. Provide augmented reality information to enable. Third, new location information is fed back to the environment-specific additional information server according to the movement of the smartphone in order to focus the camera on the smartphone. Fourth, 3D image, text, voice, and multimedia data about a specific object are augmented on the camera image to show various additional information.

The above situation can be summarized as follows.

Access the additional information server embedded in the object of interest (road, building, terrain, etc.) to register the location coordinates, tilt and direction information of the smartphone.

The additional information server sends a direction and position movement signal by using an arrow on the smartphone screen so that the object enters the camera correctly.

The smartphone game participant corrects the position and posture of the smartphone using this information, and the corrected new direction and position information is fed back to the additional information server.

By repeating the above process, if the position of the camera is fixed correctly, the additional information server delivers the augmented reality information about the object to be displayed on the smartphone screen.

[Air tag and filtering to provide augmented reality information]

Based on local information, the smartphone does not communicate directly with a central game server, but instead communicates directly with the environment-specific additional information server that is pre-installed at the site, to peer-to-peer, Receive guidance and requirements for the steps. This method can reduce the cost of periodically using a wireless communication network such as 3G to receive augmented reality information to be provided to the smartphone from the game server, and the central game server can be remotely connected to the environment-specific additional information server. The latest information can be updated in real time.

In general, in order to provide augmented reality information on a specific object, road, building, and terrain, an air tag is used, in which augmented reality information is embedded in a smartphone or transmitted from a remote server through a wireless network. It is received and shown. At this time, a plurality of augmented reality information tag using augmented reality information filter can be selected to show only some tags.

Using this technology, you can eliminate or reduce large billboards and billboards on the street. That is, if a micro-embedded advertisement information server (which may be implemented in the environment-specific additional information server) to provide enhanced advertisement through a smartphone instead of an actual advertisement board is built and managed in a building, the smart approached near the building Phone users can see augmented billboards via Bluetooth, such as Bluetooth, that showcase buildings and their contact details and graphics in video and video. Therefore, smart phone users can see the billboard provided by augmented reality without paying a separate communication fee.

The above situation can be summarized as follows.

The environment embedded additional information server provides an augmented web for a specific object, and the smartphone becomes an augmented web browser.

Instead of bringing the augmented reality information about the object from the game server in the center, it accesses the environment-intrinsic additional information server, receives text, 2D image, 3D image and video, and augments it on the smartphone screen.

Through a smartphone screen, a banner is displayed on the wall of a specific building by augmented or a billboard is displayed on the entrance of a building.

If you browse the specific floor of the building, you can augment the phone numbers, internal images, and advertisements of the businesses on the floor (eg, hospitals, travel agencies, schools, etc.) on your smartphone.

In the above, in order to help the overall understanding of the online / offline omnipresent game implementation method according to the present invention, various features and scenarios of the present invention have been described. Therefore, hereinafter, a more detailed implementation flow and system configuration will be described.

To this end, in the following, it will be described assuming divided into two teams to play the online / offline ubiquitous game according to the present invention.

[Description of Fig. 5]

5 is a view for explaining the operation of the game server in the game implementation system according to an embodiment of the present invention.

As the online / offline ubiquitous game according to the present invention is executed, the game server first receives terminal position coordinate information of the corresponding terminal from the first team mobile terminal and the second team mobile terminal in step S510. The position coordinate information of the mobile terminal is periodically transmitted to the game server by the 'game application agent' mounted on the mobile terminal.

The terminal position coordinate information received in this way is stored in the terminal position registration unit 220 of the game server in step S520. That is, the terminal location register 220 will be updated and stored whenever the terminal location coordinate information is periodically received.

As described above, when the position coordinate information of the first team mobile terminal and the position coordinate information of the second team mobile terminal are received, the terminal position comparison unit 230 of the game server, in step S530, the two mobile terminals ( That is, it is compared whether or not the distance difference between the terminal position coordinates of two mobile terminals having different team relations is within a predetermined distance range.

According to the comparison decision result at this time, if it is determined that the distance difference exceeds the predetermined distance range, the game server performs steps S540 and S545.

That is, in the above case, the game map generation unit 240 of the game server generates the first digital game map based on the terminal position coordinate information received from the first team mobile terminal, and the server controller 280 does this. The first digital game map data generated as described above is transmitted to the fixed terminal of the first team (that is, the terminal of the online game participant belonging to the first team). Here, the first digital game map is a map modeling a real world space around the location of the first team mobile terminal, and only the location of the first team mobile terminal is displayed.

Similarly, the game map generator 240 generates a second digital game map based on the terminal position coordinate information received from the second team mobile terminal, and the server controller 280 generates the second digital game map in this manner. The game map data is transmitted to the fixed terminal of the second team. Here, the second digital game map is a map modeling the real world space around the position of the second team mobile terminal, and only the position of the second team mobile terminal is also displayed here.

Therefore, in the above case (i.e., when the first team and the second team mobile terminal are not in close proximity to each other within a predetermined distance range), the fixed terminal of each team has a game map in which only the location of the same team mobile terminal is displayed on the screen. You can check through, the location of the mobile terminal of the other team is unknown.

Contrary to the above, when it is determined that the difference in distance between the mobile terminals is narrowed within the predetermined distance range as a result of the comparison determination in step S530, the game server performs steps S550 and S555.

That is, in this case, the game map generation unit 240 of the game server is based on the position coordinate information of each terminal of the first team mobile terminal and the second team mobile terminal, and the first team mobile terminal and the Generate a third digital game map modeling real world space around a location encompassing a second team mobile terminal. In this case, the positions of the first team mobile terminal and the second team mobile terminal are displayed on the third digital game map.

The third digital game map data is transmitted to fixed terminals of respective teams, respectively. Therefore, when the distance between the two mobile terminals is narrowed within a predetermined range, the online game participant in each team can check the position of the mobile terminal of the other team. Therefore, in this case, the online game participant will be able to inform the offline game participant having the mobile terminal of the same team the location of the other team mobile terminal.

As described above, all processes from step S510 to step S555 are repeated until the game is completed. That is, the game server continuously updates and transmits the digital game map to the fixed terminals of each team while repeating the above-described process every time the terminal position is newly updated from the mobile terminal.

The operation of the game server has been described above with reference to FIG. 5. Hereinafter, the operation of the environment-specific additional information server will be described with reference to FIG. 6.

[Description of Fig. 6]

FIG. 6 is a diagram for describing an operation of an environment embedded additional information server in a game implementation system according to an exemplary embodiment of the present invention.

First, as in step S610, the environment-specific additional information server is to be performed by the first team mobile terminal and the second team mobile terminal from the game server at the location of the target index on which the environment-specific additional information server is installed. It may receive a mission (i.e., a mission of the current game phase) and information to be given when the mission is completed at this location (i.e., guide information for the next appointment phase).

Such a task and guide information may be generated by the game task generator 250 of the game server, according to an exemplary embodiment. Of course, unlike the above step S610, the mission and guidance information may be stored in advance in the game mission storage unit 330 of the environment-specific additional information server.

Subsequently, in step S620, when the embedded terminal additional information server detects a mobile terminal that enters its short-range wireless communication range among the first team mobile terminal and the second team mobile terminal, in step S630, the environment-independent additional information server is determined. The short-range wireless communication transmits information about the task of the current game phase to the searched mobile terminal.

In this case, the identification and search of the mobile terminal entering the short range wireless communication possible range may be performed by the terminal search unit 320 of the environment-specific additional information server. For example, when the terminal search unit 320 periodically monitors the presence of a terminal coming into its own short range wireless communication range or receives an entry signal indicating that the terminal has entered the short range wireless communication range from a specific mobile terminal, The mobile terminal may receive identification information of the mobile terminal through communication with the mobile terminal, and identify the terminal through the mobile terminal.

Hereinafter, for convenience of description, it will be described on the assumption that the mobile terminal entering the short range wireless communication possible range is a first team mobile terminal.

In this case, when the position coordinate information, the direction information, and the slope information of the corresponding terminal are received from the first mobile terminal as in step S640, in step S650, the environment-intrinsic additional information server (more accurately, the augmented reality information extraction unit). 360 may correspond to a direction and an inclination of the corresponding terminal at the location of the searched mobile terminal from the augmented reality information DB 350 based on the received terminal position coordinate information, terminal direction information, and terminal tilt angle information. Augmented Reality (Augmented Reality) information that can be located in the front (exterior method) to extract the augmented reality (Augmented Reality) information, and thus extracted augmented reality information under the control of the server control unit 380 to the first team mobile terminal through short-range wireless communication send.

Here, the technology for predicting / extracting augmented reality information based on the position coordinate information of the terminal, the terminal direction information, the tilt angle information, and the like is one of the augmented reality implementation technologies currently commercialized and briefly introduced above. Will be omitted.

The above step S650 may not be separately performed in a state in which information such as position coordinates / directions / tilts is not received from the first team mobile terminal in step S640. In addition, if a task performance completion signal (which may be in the form of a message) for the task of the current game stage transmitted in the previous step S630 is received from the first team mobile terminal in the meantime (see step S660), In step S670, the additional information server terminates its role by transmitting guide information and the like of the next game step to the first team mobile terminal.

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed easily.
