Description

[Technical field]

[0001] The present invention relates to an apparatus, method, and program for acoustically indicating the direction of impact in engagement training. [Background technology]

[0002] Conventionally, in combat training, trainees are equipped with sensors and displays that display sounds, and for artillery fire from heavy weapons, the impact position and effective range are set.

[0003] In the engagement training, the trainee is not shot with live ammunition, but instead is considered to have been hit by artillery fire when he or she enters a set impact point or effective range. In this case, the trainee is given appropriate damage by a sensor attached to the trainee vibrating or a display outputting a sound, etc. This allows the trainee to recognize that he or she has been hit.

[0005] However, in such conventional combat training, although the trainee can recognize that a shot has been fired, he or she does not know the specific circumstances at the time of the shot, such as where the shell was fired from or where it landed that caused the shot to be fired.

[0006] This not only prevents trainees from taking correct evasive action, but also prevents them from gaining new knowledge that can be applied to future training and actual combat, resulting in a failure to obtain a high level of training effectiveness.

[0007] The present invention has been made in consideration of the above circumstances, and has an object to provide an apparatus, method, and program for acoustically indicating the direction of a shell so that a trainee can understand the specific situation when he or she is deemed to have been hit during combat training. [Means for solving the problem]

[0008] The audio simulation device of one embodiment is a device that uses audio to demonstrate to a trainee the direction of a shell from a firearm, and is equipped with a receiving unit that receives information including the launch position and impact position of the shell, a position sensor that measures the trainee's position, a first calculation unit that calculates the absolute launch direction and absolute impact direction of the shell based on the launch position, impact position, and trainee's position, an orientation sensor that measures the trainee's orientation, a second calculation unit that calculates the relative launch direction and relative impact direction of the shell with respect to the trainee's position based on the trainer's orientation, absolute launch direction, and absolute impact direction, a plurality of sound generators that are respectively arranged in different orientations, and an output control unit that causes a sound indicating impact to be output from the sound generator among the plurality of sound generators that is provided in an orientation that most closely matches the relative impact direction.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as the actual ones. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with respect to the previous drawings are given the same reference numerals, and detailed explanations and duplicated explanations are omitted as appropriate.

[0011] FIG. 1 is a functional block diagram showing an example of the configuration of an audio presentation device to which an audio presentation method according to an embodiment of the present invention is applied.

[0012] The audio simulation device 10 is a device worn by a trainee during combat training, and uses audio to simulate to the trainee the direction of a shell from a firearm.

[0013] The acoustic simulation device 10 includes a receiving section 12, a position sensor 14, a position calculator 16, a direction sensor 18, an angle calculator 20, an output control section 22, and a simulator 24.

[0014] The receiving unit 12 can communicate with a server-side communication device 40 via a dedicated communication network 50. Using this communication function, the receiving unit 12 receives information including the launch position a, launch time b, and impact position c of a shell from the communication device 40. The receiving unit 12 outputs the received information including the launch position a, launch time b, and impact position c of a shell to the position calculator 16.

[0015] The position sensor 14 measures the position of the trainee and outputs position information d, which is the measurement result, to the position calculator 16. This position information d indicates not only the position of the trainee but also the position of the audio presentation device 10 itself, so this measurement result will hereinafter be referred to as "self-position."

[0016] The position calculator 16 calculates the absolute launch direction e and absolute impact direction f of the shell based on the launch position a, impact position c, and self-position d, and outputs them to the angle calculator 20. The position calculator 16 further calculates the impact time g when the shell hits the impact position, taking into account the launch time b, and outputs them to the angle calculator 20. The launch time b output from the receiver 12 is also output to the angle calculator 20.

[0017] The orientation sensor 18 measures the orientation of the trainee and outputs orientation information h, which is the measurement result, to the angle calculator 20. This orientation information h not only indicates the position of the trainee but also indicates the orientation of the audio presentation device 10 itself, so this measurement result is hereinafter also referred to as "self-orientation."

[0018] The angle calculator 20 calculates the launch relative direction i and the impact relative direction j of the shell with respect to the trainee's position based on the self direction h, the launch absolute direction e, and the impact absolute direction f, and outputs them to the output control unit 22. The angle calculator 20 also outputs the launch time b output from the position calculator 16 to the output control unit 22.

[0019] The output control unit 22 generates demonstrator operation information k, which is instruction information for operating the demonstrator 24, based on the relative launch direction i, the relative impact direction j, the launch time b, and the impact time g, and outputs it to the demonstrator 24.

[0020] The demonstrator 24 is composed of one or more sound generators.

[0021] An example of the demonstrator 24 being realized by a plurality of sound generating devices is not limited to a particular one, but may be a neck speaker type demonstrator 24a as shown in FIG.

[0022] This simulator 24a is configured by disposing a plurality of speakers 32, which are sound generators, discretely along the outer periphery of a U-shaped mounting part 30 worn by the trainee.

[0023] An example of the demonstrator 24 being realized by a single sound generator is not limited to an example, but may be an earphone-type demonstrator 24b as illustrated in FIG.

[0024] In an audio simulation device 10 having a simulator 24a as exemplified in FIG. 2, the output control unit 22 can generate simulator operation information k that instructs the simulator 24a to output a sound indicating impact at impact time g from the speaker 32, among the multiple speakers 32 arranged in the simulator 24a, that is arranged in an orientation that most closely matches the relative impact orientation j, and output the information to the simulator 24a.

[0025] The output control unit 22 can further generate simulator operation information k including an instruction to output a sound indicating the firing of a shell at the firing time b from the speaker 32 among the multiple speakers 32 that is located in a direction that most closely matches the relative firing direction i, and output the information to the simulator 24a.

[0026] On the other hand, the output control unit 22 can also generate simulator operation information k that instructs one of the multiple speakers 32 to output stereophonic sound, in which the sound indicating the impact of a shell can be heard from the relative impact direction j at the impact time g, and output the information to the simulator 24a.

[0027] At this time, the output control unit 22 can further generate simulator operation information k including an instruction to output, using one of the multiple speakers 32, stereophonic sound in which the sound indicating the firing of a shell can be heard from the relative firing direction i at the firing time b, and output the generated simulator operation information k to the simulator 24a.

[0028] The simulator 24a outputs sounds and stereophonic sounds from all or some of the multiple speakers 32 in accordance with simulator operation information k from the output control unit 22 so that the direction of impact or launch can be recognized.

[0029] On the other hand, in an audio simulation device 10 having a simulator 24b as exemplified in FIG. 3, the output control unit 22 can generate simulator operation information k that instructs the earphone 34, whichever of the left and right earphones 34 is closer to the relative impact direction j, to output a sound indicating impact at the impact time g, and output the information to the simulator 24a.

[0030] The output control unit 22 can further generate simulator operation information k including an instruction to output a sound indicating a launch from the earphone 34, out of the left and right earphones 34, that is closer to the relative launch direction i at the launch time b, and output the information to the simulator 24a.

[0031] On the other hand, the output control unit 22 can generate simulator operation information k that instructs the left and right earphones 34 to output stereophonic sound such that the sound indicating the impact can be heard from the relative impact direction j at the impact time g, and output the information to the simulator 24b.

[0032] At this time, the output control unit 22 can further generate simulator operation information k including an instruction to output stereophonic sound from the left and right earphones 34 so that the sound indicating the firing of a shell can be heard from the relative firing direction i at the firing time b, and output the generated simulator operation information k to the simulator 24b.

[0033] The simulator 24b controls the volume of the left and right earphones 34 in accordance with simulator operation information k from the output control unit 22, and outputs sounds and stereophonic sounds so that the direction of impact and launch can be recognized.

[0034] In addition, regardless of whether the simulator 24 is the simulator 24a illustrated in Figure 2 or the simulator 24b illustrated in Figure 3, when the output control unit 22 generates the simulator operation information k to include an instruction to output both the sound indicating the firing of a shell and the sound indicating the impact of the shell, the output control unit 22 can also generate the simulator operation information k to include an instruction to output the sound indicating the impact at a louder volume than the sound indicating the firing.

[0035] This allows the simulator 24 to output sounds and stereophonic sounds so that the direction of impact can be recognized at impact time g. Similarly, sounds and stereophonic sounds can be output so that the direction of launch can be recognized at launch time b.

[0036] In addition, when sound or stereophonic audio is output from the simulator 24 both at the time of firing and at the time of impact, the sound is output at a low volume at the time of firing and at a high volume at the time of impact, so that the trainee L can easily distinguish between the firing of a shell and the impact of the shell.

[0037] Next, an example of the operation of the audio simulation device to which the audio simulation method according to the embodiment of the present invention configured as above is applied will be described.

[0038] FIG. 4 is a flowchart showing an example of the operation of the sound presentation device 10. As shown in FIG.

[0039] The audio simulation device 10 is worn by a trainee L during engagement training, as shown in FIGS.

[0040] The sound presentation device 10 can communicate with a server-side communication device 40 via a dedicated communication network 50 .

[0041] The communication device 40 transmits information including the shell firing position a, the firing time b, and the impact position c to the audio simulation device 10 via the communication network 50 (S1).

[0042] The information including the launch position a, launch time b, and impact position c transmitted from the communication device 40 is received by the receiver 12 of the audio display device 10 and output to the position calculator 16 (S2).

[0043] Meanwhile, the position sensor 14 measures the position of the trainee L (the audio simulation device 10), and outputs position information (also called "self-position") d, which is the measurement result, to the position calculator 16 (S3).

[0044] In the flowchart of FIG. 4, step S3 is shown after step S2, but steps S2 and S3 may be performed simultaneously or in the reverse order.

[0045] Next, the position calculator 16 calculates the absolute launch direction e and absolute impact direction f of the shell based on the launch position a, impact position c, and self-position d, and outputs them to the angle calculator 20. The position calculator 16 further calculates the impact time g when the shell hits the impact position, taking into account the launch time b, and outputs it to the angle calculator 20. The launch time b output from the receiver 12 is also output to the angle calculator 20 (S4).

[0046] Meanwhile, the orientation sensor 18 measures the orientation of the trainee L (the audio display device 10), and the orientation information (also called "self-orientation") h, which is the measurement result, is output to the angle calculator 20 (S5).

[0047] In the flowchart of FIG. 4, step S5 is shown after step S4, but steps S4 and S5 may be performed simultaneously or in the reverse order.

[0048] In the angle calculator 20, based on the self-orientation h, the absolute launch orientation e, and the absolute impact orientation f, the launch relative orientation i of the shell and the relative impact orientation j are calculated with respect to the position of the trainee L, and are output to the output control unit 22. In addition, the launch time b output from the position calculator 16 is also output to the output control unit 22 (S6).

[0049] In the output control unit 22, based on the relative launch direction i, the relative impact direction j, the launch time b, and the impact time g, demonstrator operation information k, which is instruction information for operating the demonstrator 24, is generated and output to the demonstrator 24 (S7).

[0050] Examples of the indicator 24 include a neck speaker type indicator 24a as illustrated in FIG. 2, and an earphone type indicator 24b as illustrated in FIG.

[0051] The neck speaker type simulator 24a is worn around the neck of the trainee L, as shown in Fig. 5. The earphone type simulator 24b is worn on the ears of the trainee L, as shown in Fig. 6.

[0052] The neck speaker type demonstrator 24a has a U-shaped mounting part 30 worn by the trainee L, and multiple speakers 32, which are sound generators, are discretely arranged along the outer periphery of the U-shape of the mounting part 30.

[0053] Both the neck speaker type indicator 24a and the earphone type indicator 24b can output sound or stereophonic sound so that the direction of impact or launch can be recognized. Therefore, from step S7 onwards, the explanation will be given separately for the case of direction indication by sound and the case of direction indication by stereophonic sound.

[0054] First, the azimuth indication by sound will be described using steps S7A and S8A. Here, as an example, a case where the azimuth indication is realized by the indicator 24a will be described, but it should be recognized that the azimuth indication by sound can also be realized by the indicator 24b.

[0055] In the audio simulation device 10 having the simulator 24a, the output control unit 22 generates simulator operation information k that instructs the simulator 24a to output a sound indicating impact at the impact time g from the speaker 32, among the multiple speakers 32 arranged in the simulator 24a, that is located in an orientation that most closely matches the relative impact orientation j (S7A).

[0056] In response to this, at the impact time g, a sound indicating the impact is output from the speaker 32 provided in the direction that most closely matches the relative impact direction j (S8A). This enables the trainee L to grasp when and in which direction the shell hit.

[0057] In addition, in step 7A, the output control unit 22 can also optionally generate an instruction to include in the simulator operation information k an instruction to output a sound indicating the firing of a shell at the firing time b from the speaker 32 among the multiple speakers 32 that is located in an orientation that most closely matches the relative firing orientation i.

[0058] As a result, in step S8A, at the firing time b, a sound indicating firing is output from the speaker 32 provided in the direction that most closely matches the relative firing direction i, allowing the trainee L to grasp when and in which direction the shell was fired.

[0059] Next, the azimuth indication by the stereophonic sound will be described using steps S7B and S8B. Here, as an example, the case where the azimuth indication is realized by the indicator 24b will be described, but it should be recognized that the azimuth indication by the stereophonic sound can also be realized by the indicator 24a.

[0060] In the audio simulation device 10 having the simulator 24b, simulator operation information k is generated which instructs the left and right earphones 34 to output stereophonic sound such that the sound indicating the impact can be heard from the relative impact direction j at the impact time g (S7B).

[0061] In response to this, at the impact time g, stereophonic sound is output from the left and right earphones 34 so that the sound indicating the impact is heard from the relative impact direction j (S8B). This enables the trainee L to grasp when and in which direction the shell hit.

[0062] Similarly, in this case, in step S7B, the output control unit 22 can also generate, as an option, an instruction to include in the simulator operation information k an instruction to output stereophonic sound from the left and right earphones 34 such that the sound indicating the firing of a shell can be heard from the relative firing direction i at the firing time b.

[0063] As a result, in step S8B, at the firing time b, a stereophonic sound is output from the left and right earphones 34 such that the sound indicating the firing of a shell can be heard from the relative firing direction i, allowing the trainee L to grasp when and where the shell was fired.

[0064] In addition, regardless of whether the simulator 24 is the simulator 24a illustrated in Figure 2 or the simulator 24b illustrated in Figure 3, when the output control unit 22 generates the simulator operation information k to include an instruction to output both the sound indicating the firing of a shell and the sound indicating the impact of the shell, the output control unit 22 can also generate the simulator operation information k to include an instruction to output the sound indicating the impact at a louder volume than the sound indicating the firing.

[0065] As a result, the simulator 24 outputs the sound of a shell being fired at a low volume and the sound of a shell hitting at a high volume, making it possible for the trainee L to easily distinguish between the firing of a shell and the sound of a shell hitting.

[0066] As described above, the audio simulation device to which the audio simulation method according to the present embodiment is applied enables the trainee to grasp the specific situation when shot during combat training. Therefore, the trainee can not only take correct evasive action, but also obtain new knowledge to be reflected in future training and actual combat, thereby achieving a high level of training effectiveness.
