1A and 1B, a virtual training system 100 may include a training bow 110, a signal processing device 120, a display device 130, and a moving plate 140. The training bow 110, the signal processing device 120, the display device 130, and the moving plate 140 may be connected through a wired or wireless network. Here, the wired / wireless network may be a network formed using a communication method such as wired Internet, wireless mobile communication, WiFi, Zigbee, or Bluetooth.

The training bow 110 can measure the tension applied to the bow bolt to generate force information and generate direction information of the bow (or posture information of the training bow 110). Here, the force information may be a tension applied to a bowstring, or a force applied directly to an arrow fired by a bowstring. On the other hand, the direction information of the bow is generated by the training bow 110 tilting forward with respect to the instructing direction of the training bow 110 (or the shooting direction of the arrow caught by the bow of the training bow 110) A true angle, and an angle at which the training bow 110 is tilted sideways relative to the ground. The specific configuration of the training bow 110 will be described later with reference to Figs. 2A to 4G.

The signal processing apparatus 120 constitutes a virtual space (or a training field) and generates a character in the virtual space corresponding to the training bow 110 (or the user USER holding the training bow 110) And generates image data for at least a part of the virtual space on the basis of the character. Further, the signal processing device 120 can calculate the movement trajectory of the virtual arrow based on the tension (or force information) measured in the training bow 110 and the direction information. Here, the virtual arrow is an arrow fired from a character (or a virtual bow) in the virtual space corresponding to the actually fired arrow, and the movement trajectory of the virtual arrow may be a path through which the virtual arrow moves in the virtual space. On the other hand, the signal processing device 130 generates shooting image data (or image data including an image of a virtual arrow) for a virtual arrow projected from a reference point (i.e., character) in the virtual space based on the movement trajectory .

The display device 130 can display a training image based on the image data generated by the signal processing device 120. [

Referring to FIG. 1B, the display device 130 may include a projector 131 and a screen 132. The projector 131 is a device for illuminating an image on the screen 132 using light and may be disposed between a front surface of the screen 132 (or a user USER and a screen 132). For example, the display device 130 may be implemented as a CRT / LCD / LED display device and may be disposed integrally with the screen 132, or may include a head mounted display (not shown) (HMD) to be worn on a user USER, or implemented in a portable terminal and mounted on a training bow 110 (for example, a specific point corresponding to a line of sight of a user USER).

The moving plate 140 moves the inclination of the foot part (that is, the inclination formed by the upper face of the foot part with respect to the ground) based on the inclination control signal provided by the virtual training system 100 (or the signal processing device 120) And can provide the signal processing device 120 with an input signal input from a user through a guide portion (including a detection sensor) which is worn on the user's body or disposed around the user. The specific structure of the moving plate 140 will be described later with reference to Figs. 5A to 6B.

Hereinafter, the training bow 110, the moving plate 140, and the signal processing device 120 will be sequentially described.

FIGS. 2A and 2B are views showing an example of a training bow included in the virtual training system of FIG. 1A, and FIG. 3 is an illustration of an arrow included in the virtual training system of FIG. 1A.

2A-3, the training bow 110 includes a bow 210 (or body), a bowstring 220, a handle 230, a tension sensor 240 (or, A reloading module 250, an input module 260, a control module 270, and a mount (not shown). The training bow 110 may be a re-curve bow, a bow, a compound bow, or the like, or may have the same shape and size as one of the bow. Hereinafter, it is assumed that the training bow 110 is an arch, and the training bow 110 is not limited to the arch.

The bead 210 has a half-moon shape by bending a tree, a bamboo, a metal, etc., and reserves the potential energy when the bead 210 is bent. The barb 210 may be divided into an upper limb and a lower limb with respect to the handle 230.

The bowstep 220 is made of a fiber material and can be fixed in such a manner that it is connected to or caught by a nock or tip 211 of the bar 210. Here, the docker 211 is a groove at the end of the upper rim and at the end of the lower rim, and may be a portion that binds the bowstring 220.

The arrow 300 can be fired by the elasticity of the bow 210 and / or the bowstring 220 when the arrow 300 is mounted (or loaded) together with the bowstring 220.

The handle 330 is disposed in the longitudinal center of the barb 230 and can be used by a user to hold the training bow 110.

The tension sensor 240 may be placed on the docker 211 or adjacent to the docker 211 and may measure the tension (or tension) on the bowstring 220.

The recharging module 250 has a cylindrical shape having an empty space therein and is disposed forwardly at the center of the barb 210 (or the handle 230), and one end thereof is closed, The arrow 300 can be stopped. The arrow 300 is inserted into the reload module 250 via the other open end of the reload module 250 (i.e., the portion where the reload module 250 is connected to the runway 220) (I.e., the direction in which the user is positioned) along with the bowstep 220 and is moved along the empty space of the reloading module 250 and is then moved to the closed end of the reloading module 250 Can reach and stop. The training bow 110 may limit the movement of the arrow 300 to the actual distance using the reload module 250 so that the virtual training system 100 can be constructed in a relatively small space.

The recharging module 250 senses whether the arrow 300 touches one end of the recharging module 250 or determines the shooting power of the arrow 300 contacting the one end of the recharging module 250 , Hitting force) can be measured. The contact power of the arrow 300 can be used to determine whether the arrow 300 is fired or when the arrow 300 is fired and the shooting power of the arrow 300 can be used to calculate the movement trajectory of the arrow 300 . The specific configuration of the reload module 250 will be described in detail with reference to FIG. 5B.

The input module 260 may receive an input signal from a user. The input module 260 may be separately formed in the training bow 110, or integrated with the knob 230. Here, the input signal can be used to control a character in the virtual space generated by the signal processing apparatus 120. [ For example, the input module 260 may be implemented as a joystick, button, or the like. The specific configuration of the input module 260 will be described later with reference to FIG. 5C.

The control module 270 senses the posture or condition of the training bow 110 and transmits signals generated at the training bow 110 to an external (e.g., a virtual training device) (E.g., a tension sensor) provided in the power supply unit (not shown). For example, the control module 270 may include a nine axis sensor, a Bluetooth module, a battery, and the like. The specific configuration of the control module 270 will be described in detail with reference to FIG. 5D.

The arrow 300 may include a shaft 310, an arrowhead 320, an arrow collar 330, and a sludge 340. Arrows 310, arrows 330 and sludge 340 are substantially the same as common shafts 310, arrows 330, and sludge 340, and a description thereof will be omitted.

The arrowhead 320 may be made of a material having elasticity. When the arrow 300 (or the arrowhead 320) hits the reloading module 250, by absorbing the impact on the reloading module 250 by the arrow 300, the arrow 300 and reloading The damage of the module 250 can be minimized. Similarly, one end of the recharging module 250 is made of an elastic material, so that the shock caused by the arrow 300 can be absorbed.

In embodiments, the sludge 340 of the arrow 300 is connected to the bow bolt 220 and may include a switch that senses the touch of the user using the bow and generates a turn-on signal. In this case, the signal processing apparatus 120 can determine whether or not the arrow 300 is fired based on the turn-on signal.

In one embodiment, the sludge 340 of the arrow 300 may be connected to the bowstring 220. For example, the sludge 340 may have a cylindrical shape and may include a space communicated in a vertical direction through which the bow bolt 220 passes. In this case, the user can easily enjoy the virtual experience without the inconvenience of recharging the arrow 300 to the bowstring 220.

In one embodiment, the sludge 340 of the arrow 300 may further include a switch 341 operated by a user's finger. The switch 341 may be disposed on the front surface of the sludge 340 to which the user's finger is touched (i.e., the surface facing the arrowhead 320) when pulling the barb 220. For example, the switch 341 may be implemented as a pressure sensor, a touch sensor, a button, or the like. The switch 341 generates a turn-on signal when the finger of the user changes from a touched state to a disengaged state (or in a separated state), and transmits a turn-on signal To a virtual training device that is interlocked with the training bow (110). In this case, the virtual training device can recognize or determine whether the arrow 300 is fired based on the turn-on signal. For example, if the tension of the bow 110 is greater than a certain value and a turn-on signal of the switch 341 is generated, the virtual training device may determine that the arrow has been fired.

In one embodiment, the arrow 300 may further include an identification device 311 that indicates the type of arrow. For example, the identification device 311 may be a radio frequency identification (RFID) device that stores information on the type of the corresponding arrow (for example, information such as shape, length, and weight such as 117 to 123 cm, Tag, and may be attached to or embedded in the shaft block 310. In this case, the training bow 110 may identify the arrow 300 using an identifier (e.g., an RFID reader) corresponding to the identification device 311 (e.g., an RFID tag).

The movement trajectory of the arrow 300 may be different depending on the type of the arrow 300 even if a constant force (or a firing force) is applied to the arrow 300. Therefore, The identification device 311 attached to the arrow 200 automatically identifies the arrow 300 and accurately determines the movement trajectory of the arrow 300 in consideration of the type (or characteristics) of the arrow 300 Can be calculated.

Referring to FIG. 2B, an output signal of the tension sensor 240, an output signal of the reloading module 250, and an output signal of the input module 260 may be provided to the control module 270. Here, the output signal of the tension sensor 240 includes a tension signal S_TENSION indicating the magnitude of the tension applied to the bow stop 220, and the output signal of the reloading module 250 indicates whether or not the arrow 300 touches And a striking force signal S_POWER indicating a magnitude of a striking force of the arrow 300 and the output signal of the input module 260 includes a movement control signal S_MOVE indicating an input signal input from a user ).

The control module 270 generates data (for example, a digital data signal) based on the signals and a signal sensed by the control module 270 and provides the data to the signal processing device 120 . The signal sensed by the control module 270 may include an orientation signal S_ATTITUDE indicating the orientation of the training bow 110 and / or identification information S_TYPE indicating the type of the arrow 200.

Then, the signal processing unit 120 may calculate the firing speed, the movement locus, and the like of the arrow 300 based on the data provided by the control module 270. For example, the signal processing apparatus 120 may determine the firing point of the arrow 300 based on the contact signal S_CONTACT or a change in the tension, and may determine a tension at the firing point (or a firing interval including the firing point) Based on the signal S_TENSION (or tension), the attitude signal S_ATTITUDE (or attitude information such as the direction and inclination of the training bow 110), and the identification information S_TYPE (or the type of arrow) It is possible to calculate the movement locus of the arrow 300 emitted from the dragon 110.

2A-3, the training bow 110 measures the tension of the bowstring 220 that directly urges the arrow 300, so that the signal processing (not shown) associated with the training bow 110 The apparatus 120 can more accurately calculate the movement trajectory of the arrow 300 based on the tension. In addition, because the training bow 110 limits the actual launch of the arrow 300 through the reload module 250, the virtual training system 100 can be implemented in a relatively small space. Further, the training bow 110 measures the contact of the arrow 300 and / or the shooting power of the arrow 300 through the reload module 250, so that the signal processing device 120 can determine It is possible to more precisely determine the launching point of the arrow 200 and calculate the movement locus more accurately based on the shooting power of the arrow 300. [

FIG. 4A is a view showing an example of a tension sensor included in the training bow of FIG. 2A. FIG.

Referring to FIG. 4A, the tension sensor 240 may include a load cell 411 (or a load sensor), an amplifier 412, and a tension controller 413.

The load cell 411 is mounted on the dynamo 211 and can measure the force (or the tension of the bow bolt 220) applied to the dynamo 211 by the bowstring 220. For example, the load cell 411 may be a beam point type vertical type.

The amplifier 412 amplifies the measurement signal output from the load cell 411 and outputs the amplified measurement signal as an analog signal. For example, the amplifier 412 may output an analog signal of 0 to 5 volts (V). An analog signal may be provided to the control module 270.

The tension adjuster 413 can adjust the initial tension applied to the bar 210 by the barb 220. 4A, the tension adjuster 413 includes an extension extending from the body of the tension sensor 240 in the direction of one end of the barb 210, And may include a support member. For example, the support member may be inserted into the elongate piece in a rotational manner, through the elongate piece to support the bar 210, and when the support member is rotated counterclockwise, the distance between the bar 210 and the elongate piece And finally, the initial tension applied to the rib 210 can be adjusted.

On the other hand, the signal processing apparatus 120 can determine the firing point of the arrow 300 based on the change in the tension measured by the tension sensor 240. For example, the signal processing apparatus 120 monitors the tension in units of a reference time (for example, 0.5 second) and, when the current tension at the current point is decreased by 70% or more from the previous tension at the previous point, 300) is fired, and the previous point of time can be determined as the firing point of the arrow.

FIG. 4B is a diagram showing an example of a reloading module included in the training bow of FIG. 2A. FIG.

Referring to FIG. 4B, as described with reference to FIG. 2, one end may have a closed cylindrical shape. The reloading module 250 may function as a stabilizer (e.g., a stabilizer provided in the archery) that adjusts the center of gravity of the arrow depending on the position and shape of the reloading module 250.

The reload module 250 may include a touch sensor (not shown). The contact sensor may be disposed at one end E1 of the recharging module 250 to sense the arrow 300 or sense whether the arrow 300 is touching. The signal processing apparatus 120 may determine whether or not the arrow 300 is fired based on the detection signal of the touch sensor.

In one embodiment, the touch sensor may be implemented as a pressure sensor to measure the shooting power of the arrow 300. For example, the contact sensor may be configured so that the pressure from the first point of time when the pressure generated by the arrow 300 rises above the reference pressure to the second point of time when the pressure generated by the arrow 300 falls below the reference pressure The shooting power of the arrow 300 can be measured. For example, the contact sensor may determine the maximum pressure occurring during the first time point to the second time point as the shooting power of the arrow 300, or accumulate the pressure occurring during the first time point to the second time point The shooting power of the arrow 300 can be calculated.

On the other hand, the signal processing apparatus 120 calculates the firing rate of the arrow 300 based on the shooting power and calculates the firing rate and other information (for example, the direction of the training bow 110, the tilt, The trajectory of the arrow 300 can be calculated. However, since the shooting power of the arrow 300 may partially disappear depending on the material of the arrow sensor 320 and the touch sensor (for example, elastic material), the signal processing apparatus 120 may reduce the shooting power of the arrow 300 (For example, the movement locus calculated on the basis of the tension of the tension sensor 240) can be corrected using the calculated locus.

4C is a diagram showing an example of an input module included in the training bow of FIG. 2A.

4C, the input module 260 determines whether or not the position of the character (or the training bow 110) corresponding to the user USER (or the training bow 110) in the virtual space (i.e., virtual training field) The direction of the eyes of the user. The input module 260 may include a movement switch 431 and an auxiliary switch 432.

The movement switch 431 can generate a movement signal for moving the character in the virtual space. That is, the character in the virtual space can move according to the operation of the movement switch 431. For example, the movement switch 431 may be implemented as a four-way jog type joystick and attached to the upper right side of the inner side of the handle 230 (e.g., the upper right side of the side of the handle 230 visible to the user) . In this case, the user can operate the movement switch 431 by using the thumb of the left hand holding the knob 230. Movement signals in the forward / backward / left / right directions can be generated in accordance with the movement of the movement switch 431 in the forward / backward / left / right direction, similar to a general joystick. The signal processing device 120 may receive a moving signal through a wire / wireless communication method and move a character in a virtual space in response to a moving signal.

The auxiliary switch 432 may provide additional input for the simulation provided by the virtual training device. For example, the auxiliary switch 432 can control the visual direction of the character in the virtual space. For example, the auxiliary switch 432 operates in a button manner and may be disposed on the right side of the handle 230. In this case, the user can operate the auxiliary switch 532 by using the stop finger of the left hand holding the knob 230. The auxiliary switch 432 may include two or more buttons.

FIG. 4D is a view showing an example of a control module included in the training bow of FIG. 2A.

Referring to FIG. 4D, the control module 270 may include a tilt sensor 441 and a communication module 442. In addition, the control module 270 may further include a battery for supplying power to the tension sensor 240 and the like.

The tilt sensor 441 can sense the posture of the training bow 110. For example, the tilt sensor 441 is implemented as a multi-axis sensor (or 9-axis sensor) including a 3-axis acceleration sensor, a 3-axis gyro sensor, and a 3-axis geomagnetic sensor, Angle, height, and so on.

The attitude information (i.e., the inclination, the position, the attitude signal S_ATTITUDE described with reference to FIG. 2B) of the training bow 110 measured by the inclination sensor 441, for example, calculates the trajectory of the arrow 300 Or may be used to control the movement or screen of the character in the virtual space implemented in the virtual training device that is interlocked with the training bow 110. [ For example, the signal processing apparatus 120 may calculate a shooting direction (and a shooting angle) based on the inclination of the bow 110, and calculate a shooting direction and a shooting speed (for example, The shooting power measured in the loading module). For example, the signal processing device 120 may be configured to determine a change in a first angle of rotation of the training bow 110 relative to an axial direction of a bow 210 of the training bow 110, It is possible to move the view direction of the character or the screen provided to the user to the left or the right based on the user based on the change amount of the second angle at which the axis of the bar 210 is inclined.

The communication module 442 receives the signals output from the tension sensor 240, the recharging module 250 and the input module 260 and the tilt sensor 541 and converts the signals into data signals and outputs them to the signal processing device 120 . For example, the communication module 442 may convert the signals to a data signal using a low-power short-range wireless communication method such as Bluetooth technology or low-power Bluetooth technology (BLE). Since the communication protocol used by the communication module 442 uses a general communication protocol, a description thereof will be omitted.

In one embodiment, the control module 270 may further include an identifier 443. As described with reference to FIGS. 2A and 3, the arrow 300 includes an identification device (for example, an RFID tag) that stores the type information of the arrow, and the identifier 443 includes an identification device , An RFID reader).

In one embodiment, the control module 270 may further include an interlock device (not shown) with an external device. For example, the training bow 110 may include an interlock device for interlocking with a head mounted display (HMD).

FIG. 4E is a diagram showing an example of controlling a screen using the control module of FIG. 4D. FIG.

Referring to FIGS. 1A, 4D, and 4E, the signal processing apparatus 120 moves the visual line direction of the character in the virtual space based on the direction information measured by the tilt sensor 441 of the control module 270, The image output through the display device 130 can be moved or changed. Here, the direction information may include the direction information of the arrow 300 emitted by the training bow 110, the up / down tilt information of the bow 210, and the tilt information of the bow 210.

In this case, the signal processing apparatus 120 can move the visual line direction of the character in the virtual space based on the change of the tilt information of the rib 210. For example, the signal processing apparatus 120 calculates the amount of change of the direction information (e.g., the left-right tilt information) every unit time, and when the amount of change in the direction information It is possible to move the direction of the line of sight of the character, or to move or change the image.

4E, when the user USER tilts the training bow 110 to the left, that is, when the user USER rotates in the state where the shooting direction of the training bow 110 is fixed by the screen 132 When the training bow 110 is tilted to the left by 30 degrees or more, the signal processing device 120 can move the visual direction of the character in the virtual space by 30 degrees to the left. Similarly, when the user USER tilts the training bow 110 to the right, i.e., when the user USER moves the training bow 110 to the training bow 110 with the shooting direction of the training bow 110 fixed by the screen 132 ) Is inclined to the right by 30 degrees, the signal processing apparatus 120 can move the visual line direction of the character in the virtual space by 30 degrees to the right. The amount of change in the shooting direction of the training bow 110 (i.e., the amount of change in the tilt) and the moving angle of the character in the sight line direction are illustrative and the present invention is not limited thereto.

Fig. 4F is a view showing an example of a cradle included in the training bow shown in Fig. 2A.

Referring to FIG. 4F, the cradle 280 is disposed on the rib 210, and can fasten an external device (e.g., a mobile terminal). For example, the cradle 280 may be disposed between the handle 230 and the upper rim so that the external device corresponds to the user's line of sight when the user is preparing to shoot an arrow through the training bow 110 .

FIG. 4G is a view showing an example of a proximity sensor included in the training bow of FIG. 2A.

Referring to FIGS. 2A and 4G, the training bow 110 may further include proximity sensors 471 and 472. Proximity sensors 471 and 472 can measure a first distance L1 from proximity sensors 471 and 472 to arrow 300 or a second distance L2 between proximity sensors 471 and 472 have.

For example, the first proximity sensor 471 may be implemented as an infrared sensor to measure the first distance L1. In another example, the first proximity sensor 471 is implemented as a magnetic sensor or magnet that forms a magnetic field, and the second proximity sensor 472 is implemented as a magnetic field measurement sensor (or electromagnetic sensor) The second distance L2 between the first proximity sensor 471 and the second proximity sensor 472 can be measured.

Note that, even if the same tension N1 is applied to the bowstring 220, the shooting forces N2 and N3 applied to the arrow 300 may be different depending on the size and type of the training bow 110. [ Therefore, when considering only the tension N1, the signal processing apparatus 120 can accurately calculate the launching speed based on the launching force N2 and the launching force N2 of the arrow and the trajectory of the arrow 200 based on the launching speed It is hard to calculate. Accordingly, the signal processing apparatus 120 can experimentally measure the emission rate / movement trajectory according to the tension N1, the bow type, and the arrow type, and store it as a lookup table. However, .

On the other hand, since the training bow 110 measures the first distance L1 or the second distance L2, the signal processing apparatus 120 can measure the first distance L1 or the second distance L2 based on the first distance L1 or the second distance L2. (I.e., the force exerted on the arrow 200) of the arrow 300 can be more accurately measured. Thus, the trajectory of the arrow 300 can be accurately calculated even without a separate look-up table or the like.

When the first distance L1 (or the second distance L2) is measured, the launching force N2 is calculated based on the first distance L1 and the tension N1 according to the following equation (1) .

[Equation 1]

N1 is the angle formed by the bow 220 and the arrow 300 and L1 is the angle between the proximity sensor or the arrow 300 and the arrow 300, LS is half of the length of the bowstring 220 between the dynamos 211. [

On the other hand, since the second distance L2 is twice the first distance L1, the emission force N2 can be calculated using the equation (1) even when the second distance L2 is measured.

Therefore, the signal processing apparatus 120 can calculate the launching force N2 applied to the arrow 300 and can calculate the launching force N2, the arrow type information (for example, the weight of the arrow 300, (That is, the movement trajectory of the arrow 300 when the arrow 300 is fired from the training bow 110) can be more accurately calculated on the basis of the motion equation and the like.

FIG. 5A is a view illustrating an example of a moving plate included in the virtual training system of FIG. 1A, and FIG. 5B is a view illustrating an example of a driving unit included in the moving plate of FIG. 5A.

5A and 5B, the moving plate 140 may include a foot plate 510, a driving unit 530, and a guide unit 520. The moving plate 140 is interlocked with the signal processing device 120 and detects the inclination of the footrest 110 based on the inclination control signal provided from the signal processing device 120 And the input signal input from the user through the guide unit 520 can be provided to the virtual training device.

Referring to FIG. 5B, the footrest 510 has a flat plate shape and can support a user's foot. For example, the footrest 510 may have a square plane of 1 m * 1 m in size. This is an example, and the footrest 510 is not limited thereto. For example, the footrest 510 may have a circular plane with a diameter of 1 m, or may have a polygonal shape.

The footrest 510 may include a first footrest 511 and a second footrest 512. The first footrest 511 can directly support the user by contacting the foot of the user. The second footplate 512 has substantially the same shape as the first footplate 511 and may be disposed under the first footplate 511.

The driving unit 530 can adjust the inclination angle of the upper surface of the pedestal 510 with respect to the ground surface (i.e., the inclination angle formed by the upper surface of the pedestal 511 with respect to the ground). The driving unit 530 may be disposed between the first footrest 511 and the second footrest 512.

The driving unit 530 may include a height adjusting member 531, a driving unit 532, a driving control unit 533, and a supporting shaft 534.

First, the supporting shaft 534 has a bar shape and is arranged to extend in the vertical direction from the center of the area of the second scaffold 512 and is rotatably connected to the central area of the area of the first scaffold 511, (511).

The height adjusting members 531 are spaced apart from each other by a specific angle with respect to the center of the area of the second footstep 512 (or the supporting shaft 534), and can support the first footstep 511. For example, the driving unit 530 includes first and second height adjusting members 531a and 531b, and the first and second height adjusting members 531a and 531b include the edge of the second footstep 512 And may be disposed so as to be spaced apart from each other by 90 degrees with respect to the center of gravity (or the support shaft 534) of the second footplate 512. This is illustrative, and the height adjustment members 531 are not limited thereto. For example, the driving unit 530 may include three or more height adjustment members 531.

In one embodiment, the height adjustment member 531 may be driven hydraulically or pneumatically. For example, the length of the height adjusting member 231 (that is, the length in the third direction D3) may vary based on the hydraulic pressure or the air pressure formed by the driving device 532. [

In one embodiment, the height adjustment member 531 may be composed of a driving device 521, a first footrest 511, and two connecting members that are pivotally connected to each other. For example, when the driving device 521 is embodied as a motor, the first connecting member may be realized in the form of a bar, and the center of the first connecting member may be perpendicularly connected to the rotation axis of the motor. One end of the second connecting member is connected to one end of the first connecting member and the other end of the second connecting member is connected to the connecting member formed on the first supporting plate 511, Lugs < / RTI > In this case, the overall length of the connecting member in the vertical direction is changed according to the rotation of the motor, and the height of the first footrest 511 can be changed with respect to the second footrest 512.

The driving device 532 may vary the length of each of the height adjusting members 531. [ For example, the driving device 532 may be embodied as a motor that forms a hydraulic or pneumatic pressure, and may include a plurality of motors corresponding to each of the height adjustment members 531.

The drive control unit 533 receives the tilt control signal from the virtual training device and determines the hydraulic pressure / air pressure corresponding to the height or the height of each of the height adjustment members 531 based on the tilt control signal, ) Can be controlled.

1 and 2, the driving unit 530 absorbs the impact of the first footstep 511 and maintains the interval between the first footstep 511 and the second footstep 512 at an allowable interval or more (For example, a spring member) and the like.

Referring again to FIG. 1, the guide unit 520 can guide the movement of a user (i.e., a user using a moving plate).

The guide portion 520 may include a wearing member 521 and a connecting member 522.

The wearing member 521 may be mounted on a part of the user. For example, the wearing member 521 is formed in an annular shape and can be mounted on or worn by the user's waist. The user can stand in the second direction D2 (or the opposite direction to the second direction D2) and can take the first direction D1 of the wear member 521 in consideration of the shape of the waist section of the user, May be greater than the second width of the wear member 521 in the second direction D2.

The wear member 521 is disposed at a distance from the upper surface (or the first foot plate 511) of the foot plate 510 by a reference distance (for example, 1.1 m), and the center of gravity of the wear member 521 (E.g., a vertical axis parallel to the third direction D3) passing through the center of the area of the footrest 510 (or the center of gravity). The height of the wear member 521 (i.e., the distance spaced from the first foot plate 511) can be freely set in consideration of the user's body characteristics (e.g., the user's key, etc.).

The connecting member 522 is disposed on the upper surface of the foot part 110 and can be connected to the wear member 521 to support the wear member 521. [ The connecting member 522 supports a certain amount of force in the downward direction along the axial direction of the connecting member 522 to ensure the safety of the user together with the wearing member 521. [

The connection length L1 corresponding to the connection angle A1 between the connection member 522 and the foot plate 510 and the separation distance between the foot plate 510 and the wear member 521 can be adjusted have.

For example, the connecting member 122 includes two cylindrical bars and two rotating connecting members, and one end of the first bar is connected to the pedestal portion 510 through the first rotating connecting member And the second bar has a diameter smaller than the diameter of the first bar and is inserted into the interior of the first bar and one end of the second bar is connected to the elastic member disposed inside the first bar to protrude into the first bar of the tart (That is, the protruding length of the second bar can be adjusted), and the other end of the second bar can be connected to the wear member 521 through the second rotation connecting member.

In the meantime, although two connecting members 522 are shown in Fig. 1, this is merely an example, and the connecting member 522 is not limited thereto. For example, the moving plate 140 may include one connecting member or three or more connecting members.

The connection angle A1 and the connection length L1 of the connection member 522 can be used to generate a movement control signal in the control unit 550 (see FIG. 5C) or the signal processing device 120 described later. Here, the movement control signal may be used to control the movement of the virtual character generated corresponding to the user in the virtual space implemented by the virtual training system 100. [

Meanwhile, the guide unit 520 may include a plurality of pressure sensors 523 disposed on the inner surface of the wear member 521 and sensing pressure generated by the user's movement.

For example, the pressure sensors 523 are arranged in the front / rear / left / right direction of the inner surface of the wear member 521 with respect to the center of gravity of the wear member 521, , The movement in the front / back / left / right direction of the waist). The pressure signal generated by the pressure sensors 523 may be used to control the movement of the virtual character. For example, when the user steps one foot in the first direction D1 to move in the first direction D1, the center of gravity of the user and the position of the waist of the user move in the first direction D1, Pressure may be applied to the pressure sensor located in one direction (D1). In this case, the virtual training device may move the virtual character in the first direction D1 based on the pressure sensed by the pressure sensor located in the first direction D1.

On the other hand, the moving plate 140 can generate a movement control signal based on the connection angle A1 and the connection length L1 of the connection member 522. [ The configuration for generating the movement control signal will be described with reference to Figs. 5C and 5D.

FIG. 5C is a block diagram showing an example of the moving plate of FIG. 5A, and FIG. 5D is a view illustrating an operation of the control unit included in the moving plate of FIG. 5A.

Referring to FIG. 5C, the moving plate 140 may include a sensor unit 540, a control unit 550, and a drive control unit 533.

The sensor unit 540 can sense the movement of the user and the user's surrounding environment. The sensor unit 540 may include a pressure sensor 541, a guide sensor 542, and a detection sensor 543.

Since the pressure sensor 541 is substantially the same as the pressure sensor 523 described with reference to Fig. 5A, the description will not be repeated. The pressure sensor 541 can generate a pressure signal S_CONTACT by sensing the pressure generated according to the movement of the user. The pressure signal S_CONTACT may include direction information on the direction in which the pressure is generated and intensity information on the magnitude of the pressure.

In this case, the control unit 550 generates an input signal (for example, a signal used to generate the movement control signal of the character based on the user's motion) based on the pressure signal S_CONTACT, To the signal processing apparatus 120.

The guide sensor 542 can detect the connection angle A1 and the connection length L1 of the connection member 522 and generate the tension signal S_TENSION and the angle signal S_ANGLE.

Referring to FIG. 5D (a), a plan view of the moving plate 140 is shown. The moving plate 140 includes first to fourth connecting members 571 to 574 (or first to fourth sub connecting members), first to fourth guide sensors 561 to 564 First to fourth sub-guide sensors).

The first to fourth connecting members 571 to 574 are connected between the footrest 510 and the wearer 521 as described with reference to Figure 5A, As shown in FIG.

The first to fourth guide sensors 561 to 564 are disposed at one end of the first to fourth connecting members 571 to 574 (for example, at a portion connected to the foot part 510) The connection angles A1 to A4 and the connection lengths L1 to L4 of the fourth to fourth connection members 571 to 574, respectively, can be measured.

In this case, the control unit 320 generates an input signal (or a movement control signal) based on the connection angles A1 to A4 and the connection lengths L1 to L4, and outputs the generated input signal to an external processor 10) (or a virtual training device).

Referring to FIG. 4 (b), for example, when the user takes one foot of the user in the first movement direction MD1 to move in the first movement direction MD1, Is moved in the first moving direction MD1 and accordingly the wearing member 521 can move in the first moving direction MD1. In this case, the first connection length L1 of the first connection member 571 decreases and the first connection angle A1 of the first connection member 571 increases in the first rotation direction DR1, The second connection length L2 of the member 572 may increase and the second connection angle A2 of the second connection member 572 may increase in the first rotation direction DR1. Accordingly, the control unit 550 determines that the user desires to move the virtual character in the virtual space in the first direction D1, and generates the first movement control signal for moving the virtual character in the first direction D1 . Similarly, the control unit 550 controls the operation of the user (not shown) based on at least two of the connection lengths (L1 to L4) and connection angles (A1 to A4) of the first to fourth connection members It is possible to grasp the intention (that is, the intention to move the character in a specific direction) and generate the movement control signal.

Referring to (c) of FIG. 5D, for example, when the user rotates the user's body in the first rotational direction DR1 to switch the viewing direction in the first rotational direction DR1, Can rotate along the first rotation direction DR1. In this case, the first connection length L1 of the first connection member 571 increases, the first connection angle A1 increases in the first rotation direction DR1, and the second connection of the second connection member 572 The length L2 may increase and the second connection angle A2 may increase in the first rotation direction DR1. Accordingly, the control unit 550 generates a first rotation signal for rotating the virtual character in the first rotation direction DR1 (or a first rotation signal for switching the image provided to the user to the first rotation direction DR1) can do. Similarly, the control unit 550 controls the operation of the user (not shown) based on at least two of the connection lengths (L1 to L4) and connection angles (A1 to A4) of the first to fourth connection members It is possible to grasp the intention (that is, the intention to rotate the character in a specific direction) and generate the rotation signal.

Referring to FIG. 4D, for example, when the user changes his / her posture from a standing posture to a sitting posture, the height of the wear member 521 (i.e., the distance from the foot plate 510 to the wear member 521) Distance) can be lowered. The connection lengths L1 to L4 of the first to fourth connection members 571 to 574 are set such that the user has the shortest distance in the standing posture and increases in the posture in which the user is seated and the connection angles A1 to A4 May not change in the horizontal direction. That is, when the first connection length L1 of the first connection member 571 increases and the first connection angle A1 changes within the reference range (or the horizontal direction component of the first connection angle A1 changes The second connecting length L2 of the second connecting member 572 may increase and the second connecting angle A2 may vary within the reference range. Accordingly, the control unit 320 generates the first posture change signal that changes the height of the center of gravity of the virtual character (or changes the posture of the virtual character, or changes the altitude of the reference point of the image displayed to the user) . Similarly, the control unit 320 determines whether or not the user of the user is on the basis of at least two of the connection lengths L1 to L4 and connection angles A1 to A4 of the first to fourth connection members 571 to 574 The posture change signal can be generated by grasping the posture change.

Referring again to FIG. 5C, the sensing sensor 543 may sense the attitude of the object and / or the user approaching the moving plate 140. The specific configuration of the detection sensor 543 will be described later with reference to FIG. 5E.

The control unit 550 controls the operation of the driving unit 550 based on the sensing signal S_INF measured by the sensing sensor 543 or generates an attitude conversion signal corresponding to the attitude of the user, To the device 120.

5A to 5D, the moving plate 140 changes the inclination of the pedestal portion 510 (or the first pedestal 511) to give the user various experiences (for example, Feeling) can be made possible. In addition, the moving plate 140 not only ensures the safety of the user through the guide unit 520, but also controls the virtual character in the virtual space implemented by the virtual training apparatus based on the movement of the user It is possible to easily and intuitively control the virtual character in the virtual space by generating the control signal as the movement control signal, the rotation signal, and the attitude conversion signal.

6A is a view showing another example of the moving plate of FIG. 5A.

5A and 6A, the guide unit 520 may include vertical bars 581 to 584 (or guide vertical bars) and sensing sensors 610 to 640.

The vertical bars 581 to 584 are disposed on the pedestal portion 110 and can be spaced apart from each other at equal intervals along the edge of the pedestal portion 510. For example, the vertical bars 581 to 584 may be disposed at each of the corners of the pedestal portion 510. The vertical bars 581 to 584 extend in a vertical direction (e.g., the third direction D3) by a specified length, and the height of each of the vertical bars 581 to 584 may be 1.5 m, for example.

The sensing sensors 610 to 640 are substantially the same as the sensing sensors 543 described with reference to Figure 5C and are disposed in each of the vertical bars 581 to 584 to provide an object The sensing sensors 610 to 640 may be positioned at a height of 1 meter with respect to the footrest 510. For example,

The first sensing sensor 610 includes eleventh and twelfth sub-sensors 611 and 612 and the second sensing sensor 620 includes twenty-first and twenty-second sub-sensors 621 and 622, The third sensing sensor 630 includes the 31st and 32nd sub sensors 631 and 632 and the fourth sensing sensor 640 may include the 41st and 42nd sub sensors 641 and 642 have. The 11th to 42nd sub-sensors 611 to 642 may be implemented as an infrared sensor that emits / receives infrared rays.

For example, the eleventh sub-sensor 611 may emit infrared rays toward the twenty-second sub-sensor 622 and the twenty-second sub-sensor 622 may receive infrared rays emitted from the eleventh sub-sensor 611 . When an object (or another user) approaches from the outside, the twenty-second sub-sensor 622 may not receive infrared rays. In this case, the control unit 550 (that is, the control unit 550 described with reference to FIG. 3) can stop the operation of the driving unit 533.

Similarly, the twenty-first sub-sensor 621 and the thirty-second sensor 632 operate as a pair, and the thirty-first sensor 631 and the forty-second sensor 642 operate as a pair, 641 and the twelfth sensor 612 can be operated as a pair.

5E, the sensing sensors 610 to 640 have been described as sensing the approach of an external object along the edge of the foot plate 510 or along the edge of the moving plate 140. However, 640) are not limited to these. For example, the sensing sensors 610 to 640 are implemented as proximity sensors and are disposed toward the outside (i.e., in a direction that diverges outward from the center of gravity of the moving plate 140), and move the moving plate 140 By reference, you can detect that an object is approaching within a certain range.

In one embodiment, the guide portion 520 may further include an orientation sensor disposed in at least one of the vertical bars 581 to 584 to sense the orientation of the user.

6A, for example, the first sensing sensor 610 may include a first attitude sensing sensor 613, and the third sensing sensor 630 may further include a second attitude sensing sensor 633. [ have. The first attitude detecting sensor 613 emits infrared rays toward the user (or the center of gravity of the moving plate 140), and the second attitude detecting sensor 633 emits infrared rays toward the user Lt; / RTI > For example, when the user takes the line posture, infrared rays may not be received by the second posture sensing sensor 533, and the control unit 550 may recognize the line posture of the user. In another example, when the user takes a sitting posture, the second posture detecting sensor 633 can receive infrared rays, and the control unit 550 can recognize the posture that the user is not in.

As described with reference to FIG. 6A, the moving plate 140 detects the approach of an external object through the detection sensors 610 to 640 and controls the operation of the moving plate 140 (or the driving unit 530) , It is possible to prevent a safety accident from occurring. Further, the moving plate 140 further includes posture detecting sensors, so that the posture of the user can be easily recognized.

FIG. 6B is a view showing another example of the moving plate of FIG. 5A.

5A, 6A and 6B, the moving plate 140 may include vertical bars 581 to 584 and connecting members 571 to 574 (or sub-connecting members).

Each of the vertical bars 581 to 584 includes a guide groove 641 and a movement fixing member 642 that moves along the guide groove 641. The connection members 571 to 574 include vertical bars 581 to 584, (Or the movable holding member 612) and the wearing member 521, as shown in Fig.

For example, the first guide groove 641 is formed in the vertical direction (or the third direction D3) inside the first vertical bar 581, and the first movable fixing member 642 is formed along the first It can move along the guide groove 641 in the vertical direction and be fixed at a specific position. Since the height of the wearing member 121 needs to be applied differently depending on the physical condition of the user (for example, the height of the male adult, the height of the 10-year-old child, etc.), the moving plate 140 is moved by the first moving fixed member 642 May be moved and fixed to a specific position based on the user's physical condition.

The first connecting member 571 is connected between the first moving fixed member 642 and the wearing member 521 and the first connecting member 571 is made of an elastic material Lt; / RTI > Similarly, each of the second to fourth connecting members 572 to 574 is disposed between the moving fixed member (i.e., the moving fixed member included in each of the second to fourth vertical bars 581 to 584) and the wearing member 521 And may be formed of an elastic body.

In this case, the guide sensor 542 described with reference to FIG. 5C is disposed at one end (for example, the first vertical bar 581 direction) of the first connecting member 571 so that the elasticity of the first connecting member 571 And the angle between the first connecting member 571 and the first vertical bar 581 can be measured. Similarly, the guide sensor 542 is disposed at one end of each of the second to fourth connection members 572 to 574, so that the elastic force of the second to fourth connection members 572 to 574 and the elastic force of the second to fourth connection The angles formed by the members 572 to 574 and the second to fourth vertical bars 582 to 584 can be respectively measured.

Here, the elastic force and the angle correspond to the connection length and the connection angle described with reference to FIGS. 5C and 5D, and the controller 550 generates signals related to the movement, rotation, and posture conversion of the character based on the elastic force and the angle .

FIG. 7 is a diagram showing an example of a signal processing apparatus included in the virtual training system of FIG. 1A.

Referring to FIG. 7, the signal processing apparatus 120 may include a first processing unit 710 and a second processing unit 720.

The first processing device 710 may construct a virtual training field based on the training environment information and generate image data for at least a part of the virtual training field based on the user USER (or a character in the virtual training field). Herein, the training environment information includes at least one of a training mode (e.g., a recording mode, a battle mode, etc.), a bow type (e.g., archery, (E. G., Snow, rain, fog, etc.), and the like, as well as the location where the training is performed, the season can do.

The first processing unit 710 may include a scenario editing unit 711, an image processing unit 712, and a crash calculator 713.

The scenario editing unit 711 can edit a specific scenario based on the training environment information. For example, the scenario editing unit 711 can load / edit the scenario from the scenario DB included in the database 730 based on the training mode, the number of shots, the bow type, and the like.

The image processing unit 712 loads the virtual training course data corresponding to the scenario from the image database, loads the bow model or the like from the 3D model database included in the database 730 to construct a virtual training course, Character) can be generated. The image processing unit 710 may be implemented as a 3D engine (for example, a video program for generating a 3D image).

In one embodiment, the image processing unit 712 may recognize (e.g., recognize) the image data through an orientation sensor (for example, the sensor 543 described with reference to FIG. 5C or the orientation sensors 613 and 633 described with reference to FIG. (For example, the height of the line of sight) of the character on the basis of the posture of the user (for example, the line posture and the like), and generate the image data corresponding to the point of time.

2B, the posture calculation section 512 calculates the posture signal S_ATITUDE (or the direction of the training bow 110) of the training bow 110 obtained from the training bow 110, 5G), identification information (for example, the type of the arrow 300), and attitude information of the user (for example, the tilt angle of the user), the tension signal S_TENSION (or the shooting forces N2 and N3 described with reference to FIG. 5G) The movement trajectory of the arrow 300 to be fired can be calculated on the basis of the attitude of the user acquired by the detection sensors 631 and 633 described with reference to Fig.

For example, the calorific value calculation unit 512 may determine the firing position (i.e., the firing reference point, including the altitude) of the arrow 300 based on the attitude information of the user, The direction of the arrow 300 can be determined based on the signal and the movement trajectory of the arrow 300 can be calculated based on the identification information (for example, the type of the arrow 300), the launching force, and the equation of motion . A general equation can be used for the motion equation (or the locus calculation algorithm of the arrow 300), and a description thereof will be omitted.

On the other hand, the first processing unit 710 may further include a training analysis unit. The training and analysis department can generate training results based on actual impact points. For example, the training analysis unit can determine the hit or score based on the actual impact point location information (e.g., coordinate information) and the target coordinate information. The training analyzer also generates training results including actual impact points and attitude information (e.g., tilt information) of the training bow 110 and transmits the training results to the user (USER) through the display device 130 .

In one embodiment, the training analysis unit may determine that the arrow 300 fires in response to a firing direction (e.g., a user's posture or a posture of the training bow 110) during a first time period including a triggering time And the movement path of the shooting direction along with the training result can be output. For example, if the tension by the bowstep 220 increases at a first time point (e.g., 0 seconds) and the tension decreases from the maximum value at a second time point (e.g., 10 seconds) to less than 70% (E.g., the coordinates as the attitude information of the training bow 110) can be sampled periodically (for example, at intervals of 1/60 second) during the first section between the first point and the second point of time have. In this case, the training analysis unit can generate movement path data in the shooting direction based on the sampled launch direction and the sensed time point. The movement path data of the laser can be visually outputted through the image processing unit 712 and the display device 130 and the user USER can move the movement direction of the firing direction before the firing, Can be recognized.

The second processing device 520 can control the training bow 110, the display device 130, and the moving plate 140. The second processing unit 520 may include a communication unit 721, an image correction unit 722, an image capturing unit 723, an inclination control unit 724, and a control unit 725.

The communication unit 721 can perform data communication with the training bow 110, the moving plate 140, and the like. For example, the communication unit 721 receives the attitude information of the training bow 110, the launching force, the movement control signal, and the like from the training bow 110, provides the inclination control signal to the moving plate 140, (E.g., a detection signal according to approach of an external object, a user's posture detection signal, etc.) from the moving plate 140.

The image correction unit 722 determines whether or not the training image output on the display device 130 is distorted so that the first processing device 710 corrects the training image, (E. G., A firing signal). ≪ / RTI >

The slope control unit control unit 724 can calculate the slope of the position based on the terrain information of the virtual training ground and the character position information (or movement information), and generate the slope control signal based thereon.

The control unit 725 may control operations of the communication unit 721, the image correction unit 722, the image capturing unit 723, and the slope control unit control unit 724. [

Meanwhile, the database 730 may include a user database, a training database, a reservation database, and the like. The user database may store user information (e.g., name, key, weight, etc.) of the user (USER) participating in the training. The training database may store the training results provided by the first processing device 510. [ The training results may be stored in correspondence with the user information, or may be stored in correspondence with the training schedule or the like. The reservation DB can store information such as training schedule, participants, participants.

As described with reference to FIG. 7, the signal processing apparatus 120 forms a virtual training field (or virtual space) based on the training environment setting information and generates a virtual training field (or virtual space) based on the user USER And generates a movement trajectory of the arrow 300 based on the posture information of the training bow 110, the identification information of the arrow 300 and the posture information of the user, and / The inclination of the moving plate 140 can be controlled based on the topographic information in the virtual space and the character position information.

The first processing unit 710 and the second processing unit 720 illustratively distinguish the signal processing unit 120 based on the image processing function and the control function. The first processing unit 710 and the second processing unit 720, 2 processing apparatus 720 are not limited thereto. For example, the second processing apparatus 720 may include a calorific value calculation section 713.

The image training system 100 may include a training bow 110 (and arrows 300, a signal processing device 120, a moving plate 140), as described with reference to Figs.

The training bow 110 measures the tension N1 of the bowstring 220 using the tension sensor 240 and the signal processing device 120 measures the tension N1 and the proximity sensor of the training bow 110 (Or the second distance L2) between the dunnets 111 obtained through the arrows 471 and 472 to calculate a launching force N2 directly applied to the arrow 300, The launching speed, locus, and the like of the vehicle can be more accurately calculated. The training bow 110 also limits the actual firing of the arrow 300 through the reload module 250 so that the virtual training system 100 can be implemented in a relatively small space, It can provide an important sense of hitting. The training bow 110 also includes a cradle 280 that holds the signal processing device 120 (e.g., a mobile terminal) The size of the virtual training system can be minimized. Further, the training bow 110 provides an interface function, such as movement of a character in a virtual space or switching of a screen implemented in the virtual training system 100 via an input module 260 (e.g., joystick, button) And uses the identifier 443 (e.g., an RFID reader) that recognizes an identification device (e.g., an RFID tag) provided on the arrow 300 to allow the user's convenience for identification of the arrow 300 The signal processing apparatus 120 can more accurately calculate the trajectory of the arrow 300 (or the launching trajectory) based on the type information of the arrow 300.

On the other hand, the moving plate 140 can change the inclination of the footrest 510, thereby enabling the user to experience various experiences (for example, a change in the terrain change). In addition, the moving plate 140 not only ensures the safety of the user through the guide unit 520, but also controls the virtual character in the virtual space implemented by the virtual training apparatus based on the movement of the user It is possible to easily and intuitively control the virtual character in the virtual space by generating the control signal as the movement control signal, the rotation signal, and the attitude conversion signal. Further, the moving plate 540 senses the approach of the external object through the detection sensors and controls the operation of the moving plate 540 (or the driving unit), thereby preventing the occurrence of a safety accident, Can be recognized.

The signal processing apparatus 120 configures a virtual training field (or virtual space) based on the training configuration information and generates a virtual training field for at least a part of the virtual training field located in the visual direction on the basis of the user USER And generates a moving trajectory and / or an impact point of the arrow 300 based on the attitude information of the training bow 110, the identification information of the arrow 300, and the attitude information of the user, The inclination of the moving plate 140 can be controlled based on the information and the position information of the character.

In the embodiments, the signal processing apparatus 120 (or the image processing unit 712) may generate image data (or image data) based on the tension of the bow 110 (or force information generated based on the tension of the bow 110) That is, data corresponding to an image displayed through the display device) of the virtual training field. Here, the partial area of the virtual training field may correspond to the field of view range of the character located in the virtual training field. For example, the signal processing apparatus 120 may change the visual field range of the character based on the direction information of the barb generated in the bow 110, and when the tension is equal to or greater than the reference tension (or the reference value) Can be reduced.

8 is a diagram showing an example of controlling an image change in the signal processing apparatus of FIG.

Referring to FIG. 8, there is shown a cross section (or a view of a space including a character and a target corresponding to the user, which is viewed from the side) of the virtual space generated in the signal processing apparatus 120 in the vertical direction.

As shown in Fig. 8 (a), the character may be located at the first point P1 and the target may be located at the second point P2. The first aiming direction D_A1 may correspond to the aiming direction of the bow 110 held by the user. The first reference angle A_R is used to determine the range of the image displayed to the user around the character, and may be set at, for example, 45 degrees. On the other hand, the visual field range corresponding to the first reference angle A_R (or the range displayed through the display device) can be set based on the first bouncing direction D_A1. For example, the field of view may be set up to a range of up to and including 22.5 degrees, that is, a total of 45 degrees, based on the ground of the virtual space. When the first bosing direction D_A1 is within a specific range (for example, within a range of 10 degrees from the upper side to 10 degrees from the lower side, from 10 degrees to the upper side and from 45 degrees to the lower side), the viewing range does not change, Is out of the specific range, the field of view can be set around the first aiming direction D_A1.

For example, as shown in (b) of FIG. 8, the field of view range can be set to a range of up and down 22.5 degrees around the second boresight direction D_A2 (i.e., the boresight direction outside the specified range). In this case, there may occur a problem that the target disappears from the visual range in accordance with the screen change.

For reference, the parabolic motion of the arrow 300 is relatively affected by gravity. Therefore, only when the arrow 300 is fired along the aiming direction D_R shown in FIG. 8A, It is possible to hit the target according to the reference trajectory TRA_R. If the user moves the bow 110 toward the second aiming direction D_A2, the target may be missing from the image displayed to the user. That is, the screen may be largely changed by the bow shooting operation.

Accordingly, when the tension of the bow 110 is greater than the basic force (that is, when the bow is determined to be pulled by the user to fire an arrow, for example, Pulled), the reference range can be increased. For example, the signal processing apparatus 120 may increase the reference range to a range of from an upper side of 10 degrees to a lower side of 10 degrees, and an upper side of 20 degrees to a lower side of 10 degrees. When the tension of the bow 110 is larger than the basic force and the second bosing direction D_A2 is out of the reference range, the signal processing apparatus 120 may be configured such that the difference between the upper maximum value of the field of view and the second boresight direction D_A2 The difference (or the difference angle A_SUB) can be reduced. For example, the difference can be reduced from 22.5 degrees to 10 degrees, 5 degrees, 0 degrees, and the like.

In this case, even if the bending direction D_A2 is out of the reference range as shown in Fig. 8 (c), the target is positioned within the visual range, and the target can be displayed through the display device .

In one embodiment, the signal processing device 120 may change the first reference angle A_R based on the tension of the bow when the tension of the bow 110 is greater than or equal to the reference value. For example, the signal processing apparatus 120 may reduce the first reference angle A_R as the tension of the bow increases beyond the reference value. In this case, an image such that the screen is enlarged around the target can be displayed through the display device.

As described with reference to Fig. 8, when the user moves the bow for bowing, the signal processing apparatus 120 adjusts the viewing range based on the bending direction of the bow 110, thereby preventing sudden change of the image , And can provide the user with a necessary image (e.g., an image including the target).

The present invention can be applied to a virtual training system using a bow, a virtual experience system, a game device, and the like.
