Referring to FIG. 1, a virtual shooting system interoperable with each other includes a plurality of haptic providing units 110 to 1n0 and a plurality of user controllers corresponding to each of the plural haptic providing units 110 to 1n0 ( 210 to 2n0) and a plurality of user controllers 2110 to 2n0 are provided with a main server 300 connected through a network.

Each of the plurality of haptic providing units 110 to 1n0 includes a plurality of devices for supporting a user to directly experience a virtual shooting, and each of the plurality of devices detects a user's motion or is operated by the user. The command signal is generated and transmitted to the corresponding user controllers 210 to 2n0. In addition, each of the plurality of devices performs a preset operation in response to a control signal applied from the user controllers 210 to 2n0. Here, a plurality of devices provided in each of the plurality of haptic providing units 110 to 1n0 will be described later.

The plurality of user controllers 210 to 2n0 receive and determine command signals applied from a plurality of devices provided in each of the plurality of haptic providing units 110 to 1n0, and control the plurality of devices according to the determined command signals. , Fire shooting simulation. On the other hand, each of the plurality of user controllers 210 to 2n0 transmits a status signal to the main server 300 for information that another user controller should recognize in the shooting simulation progress state. In addition, each of the plurality of user controllers 210 to 2n0 receives an interlocking signal generated by the main server 300 by analyzing a state signal of another user controller, and applies the analyzed interlocking signal together during the firing simulation process, thereby providing a plurality of user controllers. One user controller of the two user controllers 210 to 2n0 may be linked with at least one other user controller to perform shooting simulation. That is, the plurality of user controllers 210 to 2n0 analyze the command signals applied from the plurality of devices, respectively, and conduct shooting simulation, and simultaneously transmit a status signal to the main server 300 to transmit its simulation progress state to the main server ( Notify 300 and receive the interlocking signal from the main server 300 to proceed with the fire simulation linked to the other user controller.

The main server 300 determines the user controllers to be fired by interlocking with each other among the plurality of user controllers 210 to 2n0 and connects them to each other, and provides a status signal applied to each of the plurality of user controllers 210 to 2n0. Receives, determines the shooting simulation progress of each user controller (210 ~ 2n0), and transmits the interlocking signal generated corresponding to the determined progress state to the user controller of the plurality of user controllers (210 ~ 2n0) interworking do.

As a result, the virtual shooting system according to the present invention shown in FIG. 1 may perform shooting simulation in which a user feels realistically by a plurality of devices provided in each of the plurality of haptic providing units 110 to 1n0, and a plurality of user controllers.

In addition, a plurality of users may form a plurality of teams, and the simulation may be performed in a team-to-team manner between users.

However, in the virtual shooting system according to the present invention, each of the plurality of user controllers 210 to 2n0 may perform shooting simulation in an individual form without interworking with other user controllers.

2 illustrates a configuration of a virtual experience providing unit and a user controller according to an embodiment of the present invention.

In FIG. 2, for convenience of description, one haptic providing unit 110 and haptic providing unit 110 of the plurality of haptic providing units 110 to 1n0 and the plurality of user controllers 210 to 2n0 shown in FIG. 1 are provided. Only one user controller 210 to 2n0 is shown.

As shown in FIG. 2, the haptic providing unit 110 includes a plurality of devices such as a display device 111, a simulated firearm 112, a laser detection camera 113, a detection helmet 114, a vibration vest 115, and the like. A user identification card 116.

The display device 111 outputs a fire simulation image according to an image signal applied as a control signal from the user controller 210. The display device 111 may be implemented as a large-screen display device to provide a realistic shooting simulation image to the user. For example, the display device 111 may be implemented as a projector and a screen. Since the display device 111 simply converts an image signal applied from the user controller 210 into an image and outputs the image signal, the display device 111 may not transmit a command signal to the user controller 210.

The simulated firearm 112 is the most important device in the shooting simulation, and is a device for the user to feel that he is actually shooting. What is required of the simulated firearm 112 is that when the bullet is fired from the actual firearm, the repulsive force must be able to occur in the simulated firearm 112 when the user triggers the simulated firearm 112 as well as the repulsive force occurs. The point and the point at which the simulation simulates the location of the simulated firearm at the time of triggering the simulated firearm. Accordingly, in the present invention, a repulsive force generating means for generating a repelling force when triggering a simulated firearm is provided, and a laser pointer is provided to display a position where the simulated firearm is aimed at. Detailed description of the configuration of the simulated firearm will be described later. Since the simulated firearm 112 can trigger the firing simulation only when the trigger information is notified to the user controller 210 at the time of the trigger, the trigger signal is transmitted to the user controller 210, and the user controller 210 responds to the trigger signal. The reaction force is generated in response to the reaction force signal, which is a control signal transmitted. In addition, since the simulated firearm is performed on a simulation unlike an actual shooting experience, the simulated firearm may be provided with various additional function buttons for providing various additional functions for performing a simulation. When the simulated firearm has the additional function button, the simulated firearm transmits a brightness signal corresponding to the selected additional function button to the user controller 210 when the additional function button is selected by the user.

The laser detection camera 113 is a device for detecting a laser output when the simulated firearm 112 is triggered, and may be implemented as an infrared camera to easily detect the laser. Shooting simulation may be performed based on an image output from the display device 111. The image output from the display device 111 may continuously change as the simulation proceeds. On the other hand, the simulated firearm outputs a laser when triggered by a user's operation. The output laser is basically output as an image output to the display device 111. In order for the shooting simulation to proceed smoothly, the position of the laser output from the simulation gun 112 should be able to determine to which position of the image output from the display device 111. That is, the position of the laser output from the simulated firearm 112 and the image output from the display device 111 should be able to match each other. To do this, first, the position of the laser must be detected by detecting the output laser. That is, when the laser detection camera 113 collects an image and transmits the image to the user controller 210, the user controller 210 detects a laser from the collected image and determines a position where the laser is detected. In addition, the user controller 210 maps the image signal output to the display device 111 and the position of the detected laser to accurately determine the position where the user shot using the simulated firearm 112.

The sensing helmet 114 receives a sound signal from the user controller 210 to provide a sound effect according to the simulation progress state to the user. The sound effect may not be merely a sound, but may be provided as a directional three-dimensional stereo sound to provide a three-dimensional sense of space. In order to generate three-dimensional stereo sound, the sensing helmet may be equipped with 5.1-channel speakers or more. In addition, the sensing helmet 114 may be provided with three-dimensional glasses for three-dimensional stereoscopic images when the shooting simulation provides a three-dimensional stereoscopic image. Currently commercially available three-dimensional stereoscopic image system, such as a glasses-free, a polarizing method and a shutter glass method, but there is a problem that the implementation of a large-screen glasses-free glasses is difficult. The polarization method and the shutter glass method require mode glasses. Accordingly, the virtual shooting system of the present invention includes glasses on the sensing helmet 114. The glasses may be provided with a polarized glasses or a shutter glass glasses according to the implementation method of the three-dimensional stereoscopic image, it is assumed in the present invention that the glasses of the shutter glass glasses are used as an example. In addition, since the 3D stereoscopic image may not be implemented by glasses provided in the sensing helmet 114, the image output from the display device 111 may be in the form of a 3D stereoscopic image in order to provide a 3D stereoscopic image to the virtual shooting system. Should be provided.

In addition, the sensing helmet 114 may be provided with at least one sensor for checking the user's gaze direction. For example, the sensing helmet 114 may be provided with a gyro sensor to check the user's gaze direction. Gyro sensor is a sensor that can measure the direction and inclination by detecting the angular velocity by using a gyroscope is a sensor that has been recently applied to the mobile phone. In addition, the sensing helmet 114 may be provided with other sensors such as an acceleration sensor, a gravity sensor, and a geomagnetic sensor in addition to the gyro sensor to check the user's gaze direction. In addition, a plurality of sensors may be provided, and combinations of detection signals sensed by each of the plurality of sensors may be used to more accurately identify the gaze direction of the user.

In addition, the sensing helmet 114 may be provided with at least one vibration means to add the realism of the shooting simulation. The vibration means may be implemented by a vibration motor or the like, and when the user is hit by another user or a virtual enemy during the firing simulation, vibration may be generated to provide a realistic firing simulation to the user. The vibration means provided in the sensing helmet may be set to generate vibration only when it is determined in the shooting simulation that the user's head is hit. In addition, although not shown, the sensing helmet 114 may include a communication means for transmitting a signal with the user controller 210. If the communication means transmits a signal with the user controller 210 by wire, it may cause inconvenience to the user. Therefore, the sensing helmet 114 may include a wireless communication means for communication with the user controller 210.

The vibration vest 115 also has a plurality of vibration means as well as the sensing helmet 114 to add realism to the shooting simulation. Each of the plurality of vibration means is distributedly disposed in the vibration vest 115 so that the user can accurately represent the location to be hit so that more realistic shooting simulation can be performed. In addition, the vibration vest 115 may include a vibration controller for communicating with the user controller 210 and individually controlling a plurality of vibration means according to a control signal transmitted from the user controller 210.

The user identification card 116 stores user identification information for the user who performs shooting simulation. The user identification card 116 may be implemented as an RFID card, and may wirelessly transmit user identification information to the user controller 210. In response, the user controller 210 determines the user identification information, calls the stored user information, and proceeds to fire simulation.

One user controller 210 to 2n0 corresponding to the haptic providing unit 110 may include a graphic processor 211, a gun controller 212, a laser recognizer 213, a motion detector 214, and a vibration signal generator ( 215, a user recognition unit 216, a communication unit 217, and an information storage unit 218.

First, the graphic processor 211 is configured to correspond to the display device 111 of the haptic providing unit 110 and receives screen information to be currently displayed from the shooting simulation screen information stored in the information storage unit 218. And converts the image signal into recognizable image.

The firearm control unit 212 has a configuration corresponding to the simulated firearms 112, determines whether the simulated firearms 112 are triggered by receiving a trigger signal from the simulated firearms 112, and when the simulated firearms 112 are triggered, the repulsive force is triggered. The signal is provided to the simulated firearm so that the reaction force against the trigger is generated in the simulated firearm 112. In addition, when the simulated firearm is equipped with the additional function button, the firearm controller 212 may determine whether to select the additional function button and perform a predetermined operation corresponding to the selected additional function button. In this case, a predetermined operation corresponding to the additional function button may include control of the simulated firearm 212, but basically, the operation is for proceeding shooting simulation. An example of such an additional function button may be a function of controlling the movement of a character in a shooting simulation corresponding to a user or using a weapon other than a gun.

The laser recognition unit 213 has a configuration corresponding to the laser detection camera 113, and analyzes the image collected and transmitted by the laser detection camera 113 to detect the laser output from the simulated firearm 112, and detects the detected laser. Determine the position of. In this case, the position of the laser to be determined means not the position in the virtual space on the firing simulation but the actual position where the laser output from the simulated firearm 112 reaches the display device 111. In order to accurately detect the position of the laser, the laser recognizer 213 may use a frame groover or the like. The laser recognizer 213 converts the actual position of the laser from the information about the actual position of the laser and the image output from the display device 111 into a position in the virtual space on the shooting simulation.

The movement detecting unit 214 determines a movement of the sensing helmet 114 by analyzing a sensing signal applied by sensing at least one sensor provided in the sensing helmet 114 in a configuration corresponding to the sensing helmet 114. The determined motion may be analyzed as the movement of the gaze of the user, thereby causing the image of the virtual space on the fire simulation output to the display device 111 to change according to the movement of the gaze. In addition, the motion detection unit 214 may transmit a sound signal generated when the shooting simulation proceeds to the detection helmet 114 to output sound through a speaker provided in the detection helmet 114. In some cases, the sound processor for outputting a sound signal to the user controller 210 may be provided separately from the motion detector 214.

The vibration signal generator 215 is configured to correspond to the vibration vest 115 to generate a vibration signal so that a plurality of vibration means provided in the vibration vest 115 may individually vibrate when the user is hit on the shooting simulation. send. When the vibration helmet is provided in the sensing helmet 114, the vibration signal generator 215 may transmit a vibration signal to the sensing helmet 114 such that the vibration means included in the sensing helmet 114 vibrates.

The user recognition unit 216 is provided in the user controller in response to the user identification card 116, acquires user identification information transmitted from the user identification card 116, and calls the stored user information.

 The information storage unit 218 stores simulation information for executing shooting simulation, and when a call signal is generated for the user information from the user recognition unit 216, requests and obtains and stores the user information from the main server 300. .

In this case, the user information may include pre-stored user photographs or personal information, fire shooting state information previously performed, total information, and other user information in which fire simulation was performed in cooperation with each other. If a user image such as a user picture exists in the user information, the user's image may be applied to a character used by the user in the shooting simulation.

 In the above description, the plurality of haptic providing units 110 to 1n0 and the plurality of user controllers 210 to 2n0 are configured in a one-to-one correspondence, so that each of the plurality of user controllers 210 to 2n0 corresponds to one haptic providing unit ( Although only 110 to 1n0 has been described, in some cases, each of the plurality of user controllers 210 to 2n0 may control the plurality of haptic providing units 110 to 1n0. That is, even if there are a plurality of haptic providing units 110 to 1n0, a plurality of haptic providing units 110 to 1n0 may be controlled by one user controller. However, when the user controller controls the plurality of haptic providing units 110 to 1n0, the number of haptic providing units 110 to 1n0 that can be controlled at the same time may be limited, and at this time, the haptic providing unit 110 to 1n0 that can be controlled at the same time. The number of times may vary depending on the performance of the user controller. In the present invention, as an example, it is assumed that the number of haptic providing units 110 to 1n0 that can be controlled simultaneously by one user controller is four.

3 shows a sensing helmet according to an embodiment of the present invention.

Referring to FIG. 3, the sensing helmet according to the present invention may include at least one speaker SPK and at least one sensing sensor HSSR. The at least one speaker SPK receives a sound signal from the user controller 210 and outputs a sound. If the shooting simulation supports stereo sound, the at least one speaker SPK may include a plurality of speakers to provide a stereo sound effect. In the present invention, it is assumed that the shooting simulation supports the stereo sound, and it is assumed that the sensing helmet 114 is provided with the 5.1 channel speaker to provide the stereo sound effect. In FIG. 3, the speaker is provided on the side of the sensing helmet 114, but the position of the speaker SPK may be variously adjusted.

At least one HSSR for detecting a user's gaze direction is actually provided to detect a moving direction of the user's head rather than the user's gaze direction, and in FIG. 3, an upper part of the detection helmet 114 is disposed. Although illustrated as, it may be arranged in a position that can easily detect the movement of the user's head according to the characteristics of the sensor. As described above, the at least one sensing sensor HSSR may be implemented as a gyro sensor, an acceleration sensor, a gravity sensor, and a geomagnetic sensor.

In addition, when the shooting simulation provides a three-dimensional stereoscopic image, the front surface of the sensing helmet 114 is provided with a three-dimensional glasses for the three-dimensional stereoscopic image. As the 3D stereoscopic glasses provided in the sensing helmet 114, the 3D glasses of the polarization method or the shutter glass method may be used according to a 3D stereoscopic image. In addition, as described above, the sensing helmet 114 includes at least one vibration means in order to add realism to the shooting simulation, and vibrates in response to a vibration signal applied from the vibration signal generator 215 of the user controller 210. You can do it. Although the number of vibration means is not limited, it is illustrated in FIG. 3 as being disposed on both sides of the sensing helmet 114 as an example.

4 illustrates a simulated firearm according to an example of the present invention.

As shown in Fig. 4, the simulated firearm 112 has a form similar to an actual firearm. The shape of the simulated firearm 112 is not limited to the form of the firearm of FIG. 4, and various types of simulated firearms 112 may be used in the shooting simulation as various actual firearms exist. The muzzle of the simulated firearm 112 is provided with a laser pointer LSP. The laser pointer LSP outputs a laser when a trigger signal of the simulated firearm 112 is pulled and a trigger signal is generated. Since the laser is light having low diffusion and strong straightness, the laser serves as a bullet of the simulated firearm 112 in place of the bullet of the actual firearm. In FIG. 4, the repulsive force generating unit KIG is disposed behind the simulated firearm 112 in the simulated firearm 112. More specifically, the repulsive force generated in the repelling force generating unit KIG is arranged to correspond to the position where the bullet is triggered in the actual firearm. 4, four right side additional function buttons RB are shown in the simulated firearm 112. Although FIG. 4 illustrates the additional function button RB only on the right side of the simulated firearm 112, the additional function button may be provided on the left side. In addition, the number of additional function buttons on the right and left sides can be variously adjusted according to the setting of the shooting simulation.

5 shows the structure of the repulsive force generating means according to an embodiment of the present invention.

Although the simulated firearm 112 of FIG. 5 is different in shape from the simulated firearm 112 of FIG. 4, as described above, the simulated firearm can be implemented in various shapes similar to the shape of an actual firearm.

Referring to FIG. 5, the repulsive force generating means is an air compressor (ACP) that generates compressed air, is opened and closed in response to a trigger signal, and the compressed air generated by the air compressor by the repulsive force generating unit (KIG) is formed into a repulsive force generating unit ( And a repulsive force generating unit (KIG) for providing repulsive force to the user in the simulated firearm 112 using a solenoid valve (SV) and compressed air to be delivered to the KIG.

Looking at the process of generating the repulsive force repulsive force generating means, first, the air compressor (ACP) compresses and stores the air by driving the motor so that the compressed air is always above a predetermined pressure. At this time, since the solenoid valve SV is closed, compressed air is not transmitted to the simulated firearm 112. Then, when the user triggers the simulated firearm 112, the trigger signal is transmitted to the solenoid valve SV, and the solenoid valve SV is opened. As the solenoid valve SV is opened, the compressed air is instantaneously transferred to the air transfer pipe ARP of the repulsive force generating unit KIG through the solenoid valve SV. And the air transfer pipe (ARP) of the repulsive force generating unit (KIG) is bent in the direction of the user in the position of the simulated firearm 112 corresponding to the position of the breck (Breechblock) in which the bullet is triggered in the real gun solenoid valve (SV) Compressed air delivered through the to create a reaction force in the user direction. That is, unlike the actual firearm, the simulated firearm 112 opens and closes the compressed air generated by the air compressor ACP in the solenoid valve SV to generate a repulsive force in the repulsive force generation unit KIG of the simulated firearm.

Each of the plurality of simulated firearms is provided with individual firearm control units IGC1 to IGC4. Each of the plurality of individual firearm control units IGC1 to IGC4 determines whether the trigger is pulled by a user's operation in the corresponding simulated firearms GUN1 to GUN4, and if a trigger is pulled, a trigger signal is generated and transmitted to the gun control unit 212. do. In addition, the trigger signal is transmitted to the corresponding solenoid valves SV1 to SV4 so that the compressed air generated by the air compressor ACP is transmitted to the corresponding simulated guns GUN1 to GUN4 to generate the repulsive force.

In FIG. 5, one simulated firearm 112 is provided with an air compressor ACP and a solenoid valve SV, respectively. However, unlike the solenoid valve (SV) which operates by detecting the trigger of the simulated firearm 112, the air compressor (ACP) generates compressed air before the trigger of the simulated firearm, so even if there are a plurality of simulated firearms, one air compressor (ACP) is used. ).

The individual firearm control units ICC1 to IGC4 of FIG. 5 may be implemented by being included in the firearm control unit 212, but in some cases, may be implemented in the simulated firearms GUN1 to GUN4.

In addition, even when a plurality of users perform a shooting simulation in the same space, a plurality of users may individually perform different shooting simulations, but in some cases, a plurality of users may perform a shooting simulation on the same display device 111. It can also be done. That is, a plurality of users may share a single display device 111 to perform shooting simulation. When a plurality of users share and use one display apparatus 111, all lasers output by the simulated guns GUN1 to GUN4 corresponding to each of the plurality of users may be output to one display apparatus 111 that is shared. will be. That is, the lasers output from the plurality of simulated firearms GUN1 to GUN4 are all output to one shared display device 111. In this case, since the laser detection camera 113 collecting the image of the display device 111 performs a simple operation of simply collecting the image and transmitting the image to the laser recognition unit 213, a plurality of laser beams are displayed on the image. It is not possible to determine which of the simulated firearms GUN1 to GUN4 is the laser output from the simulated firearms. In addition, if the laser output unit 213 also outputs the lasers output from the plurality of simulated firearms GUN1 to GUN4 are all the same laser, it is difficult to determine which laser device is output from the simulated firearm. Accordingly, the present invention compares the timing of the trigger signal transmitted from each of the simulation guns GUN1 to GUN4 with the timing at which the laser is emitted, and thus, a method of determining which simulation guns GUN1 to GUN4 outputs the laser. However, this method of matching timing may lead to inaccurate results when multiple users simultaneously perform shooting simulation. Accordingly, in the present invention, the wavelength or output pattern of the laser output from the laser pointer LSP of each of the plurality of simulated firearms GUN1 to GUN4 can be set differently. That is, when the wavelength or the output pattern of the laser is set differently, the laser recognition unit 213 is reflected on the display device 111, the image collected by the laser detection camera 113 is applied to and analyzed, the collected image It is possible to determine which simulated gun the laser is displayed. The timing matching method and the method of differently setting the wavelength and the output pattern of the laser may be used in combination.

7 shows a vibration vest according to an embodiment of the present invention.

In FIG. 7, the vibration vest 115 has a plurality of vibration means FJV, BJV and a signal receiver SRU. The plurality of vibration means (FJV, BJV) may be divided into a front vibration means (FJV) and a rear vibration means (BJV) in the vibration vest 115, each of the front vibration means (FJV) and rear vibration means (BJV) It comprises a plurality of vibration means distributed. The vibration vest 115 is provided with a plurality of vibration means distributed in each of the front and rear to increase the realism of the shooting simulation. That is, when the user is hit while the shooting simulation is in progress, the vibration means disposed at the position corresponding to the hit position causes the vibration to be made, so that the user can be notified exactly where the hit has been hit. In addition, since the front vibration means (FJV) and the rear vibration means (BJV) are separated, it is possible to determine whether the user has been hit by the enemy in front, or hit by the rear enemy. The signal receiving unit SRU receives a vibration signal of which of the plurality of vibration means FJV and BJV vibrates from the vibration signal generator 215 of the user controller 210. Since the vibration vest 115 is a device worn by a user, if the user receives a vibration signal in a wired manner, the vibration vest 115 may cause inconvenience when the user performs the shooting simulation. Accordingly, the signal receiver SRU may be implemented to wirelessly receive the vibration signal.

8 illustrates a laser coordinate calculation method according to an embodiment of the present invention.

The laser coordinate calculation method in the virtual shooting system is a task of accurately matching the position of the laser output by the user with a simulated gun to the position in the virtual space on the shooting simulation. This is a factor for determining whether the user has hit or missed the target, which is one of the most important factors in the shooting simulation process. For example, if a user hits a target targeted in an image output from a display device, but the user does not accurately analyze the position of the laser coordinates and is not treated, the user loses interest in the virtual shooting system. Therefore, accurate processing of laser coordinates is essential to increase interest in the user's virtual shooting system.

Referring to FIG. 8, the laser coordinate calculation method according to the present invention will be described first, the laser detection camera 113 obtains a laser image in real time (S110). When the user triggers the simulated firearm 112 and the laser output from the simulated firearm 112 is illuminated at a specific position of the image, the laser detection camera 113 acquires the laser image output from the simulated firearm 112 It transmits to the Jay recognition unit 213. Here, the laser detection camera 113 may be configured to capture an image output from the display device 111 only when the laser is output from the simulated firearm 112, but generally an image output from the display device 111 is always available. It is preferable to take a picture and transmit it to the laser recognition unit 213 in real time.

When the laser image is acquired in real time, the laser recognizer 213 analyzes the acquired image to recognize a position where the laser is illuminated (S120). Since the laser recognition unit 213 stores the overall coordinates of the image acquired by the laser detection camera 113 in advance and stores the coordinates of the image acquired by the laser detection camera 113, the position where the laser is detected in the image. Instantly determine and recognize the actual coordinates for.

Thereafter, the laser recognition unit 213 converts the position in the virtual space on the firing simulation corresponding to the actual coordinates where the laser is detected, into a coordinate in the virtual space by matching a look up table (LUT) which is prepared in advance ( S130).

The image data of the virtual space on the shooting simulation is stored in the user controller 210 in advance, and the graphic processor 211 converts the image data necessary in the virtual space into an image signal according to the progress of the simulation as described above. Transfer to the display device 111. That is, the user controller 210 grasps the overall coordinates of the virtual space on the shooting simulation currently being output. Accordingly, since the user controller 210 knows the coordinates of the images output from the display device 111, a lookup table (LUT) matching the actual coordinates and the coordinates of the output images may be generated. When the lookup table is generated, the firing simulation can be immediately converted into coordinates in the virtual space on the fire simulation by substituting the actual position of the serer into the lookup table. However, if the shooting simulation provides a 3D stereoscopic image, it may be necessary to correct the coordinates according to the perspective. To this end, the laser coordinate calculation method according to the present invention may further perform an inverse perspective transformation.

In addition, the graphic processor 211 may display that the bullet reaches the corresponding coordinate of the image output through the display device 111 according to the coordinates in the converted virtual space. When it is determined that the laser shot from the hit, the vibration means provided in the user's detection helmet 114 and the vibration vest 115 to vibrate (S140).

As a result, the real-time interoperable virtual shooting system according to the present invention includes a plurality of haptic providing units 110 to 1n0 so that each of the plurality of users can perform realistic shooting simulation, and a plurality of user controllers 210 to 2n0. And the main server 300 transmit a status signal and an interlocking signal for the firing simulation to each other so that a plurality of users can interoperate with the firing simulation.

The device according to the invention can be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and a carrier wave (for example, transmission via the Internet). The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.

Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
