[0011] The present invention will be described below through embodiments of the invention, but these embodiments are not intended to limit the invention as defined in the claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0012] In this specification, technical matters will be explained using the orthogonal coordinate axes X, Y, and Z as appropriate. The Z axis indicates the height direction of the helmet to which the helmet mounting device is attached. The X and Y axes are axes perpendicular to the Z axis. The direction of each arrow on the coordinate axes will be expressed as the positive side of the X axis, the positive side of the Y axis, and the positive side of the Z axis, and the direction opposite to each arrow on the coordinate axes will be expressed as the negative side of the X axis, the negative side of the Y axis, and the negative side of the Z axis.

[0013] Figure 1A is a block diagram showing the configuration of a processing system 1 according to one embodiment of the present disclosure. According to Figure 1A, the processing system 1 includes at least a server device 100, a terminal device 200, and a helmet mounting device 300 (terminal device), and each device is connected to communicate via a communication line 30. For example, the terminal device 200 acquires image information and audio information acquired by the helmet mounting device 300 via the server device 100, while outputting predetermined audio information to the helmet mounting device 300. The helmet mounting device 300 is also configured to be held in a helmet, for example, and receives predetermined audio information from the terminal device 200 via the server device 100, while transmitting image information and audio information acquired by the helmet mounting device 300 to the terminal device 200.

[0014] The helmet attachment 300 can be used for a variety of industrial applications. For example, the helmet attachment 300 can be used in industrial applications, power applications, medical applications, industrial applications (including manufacturing and construction), agricultural applications, retail applications, logistics applications, environmental protection applications, leisure applications, etc. The following describes an example of how the helmet attachment 300 is used in industrial applications in the construction industry (construction sites, work sites, etc.). Work at construction sites includes, for example, work in mines, use of heavy machinery and lifts, and confirmation of work procedures at construction sites.

[0015] Here, the helmet attachment device 300 is attached to a helmet that covers the user's (worker's) head. The user wears the helmet and performs work at the construction site. The user's manager (the user's supervisor, etc.) operates the terminal device 200. This processing system 1 is used for the helmet attachment device 300 (the user's terminal device) to communicate with the terminal device 200 (the user's manager's terminal device) via the server device 100.

[0016] The communication line 30 may be a wireless network. The communication line 30 may include, but is not limited to, mobile phone networks, wireless LANs, fixed telephone networks, the Internet, intranets, and / or Ethernet (registered trademark). Because the communication line 30 is a wireless network, it does not impose any burden on the user during work at the construction site.

[0017] Figure 1B is a block diagram showing the configuration of a helmet mounting device 300 according to one embodiment of the present disclosure. Specifically, Figure 1B is a block diagram showing the configuration of a helmet mounting device 300.

[0018] The helmet mounting device 300 includes a processor 311, memory 312, input interface 313, output interface 314, communication interface 315, and sensor 316. Each of these components is electrically connected to the others via control lines and data lines. Note that the helmet mounting device 300 does not need to include all of the components shown in Figure 1B; it is possible to omit some components or add other components.

[0019] The processor 311 functions as a control unit that controls other components of the helmet mounting device 300 based on a program stored in the memory 312. The processor 311 is mainly composed of one or more CPUs, but a GPU, FPGA, etc. may be combined as appropriate.

[0020] Based on the program stored in the memory 312, the processor 311 executes the following processes based on the program stored in the memory 312: "a process to receive user operation input via the input interface 313 and start the power supply unit," "a process to receive user operation input via the input interface 313 and acquire image information," "a process to start the voice information acquisition unit and acquire voice information," "a process to transmit the image information acquired by the image information acquisition unit to the terminal device 200 via the communication interface 315," "a process to receive voice information from the terminal device 200 via the communication interface 315," and "a process to output voice based on the received voice information."

[0021] The memory 312 consists of RAM, ROM, non-volatile memory, HDD, etc., and functions as a storage unit. The memory 312 stores instruction commands for various controls of the processing system 1 according to this embodiment as programs.

[0022] Specifically, the memory 312 stores programs for the processor 311 to execute, such as "a process to receive user input via the input interface 313 and start the power supply unit," "a process to receive user input via the input interface 313 and acquire image information," "a process to start the voice information acquisition unit and acquire voice information," "a process to transmit the image information acquired by the image information acquisition unit to the terminal device 200 via the communication interface 315," "a process to receive voice information from the terminal device 200 via the communication interface 315," and "a process to output voice based on the received voice information."

[0023] The input interface 313 functions as an input unit that receives user input to the helmet mount 300. Examples of the input interface 313 include physical key buttons and a touch panel having an input coordinate system corresponding to the display coordinate system of the display. In the case of a touch panel, icons are displayed on the display, and the user makes a selection for each icon by making an operation input via the touch panel. The method for detecting user operation input by the touch panel can be any method, such as capacitive or resistive. The input interface 313 does not always need to be physically provided on the helmet mount 300, and may be connected as needed via a wired or wireless network. Therefore, in addition to the above, a mouse, keyboard, microphone for voice input, camera for gesture input, etc., can also be used as the input interface 313. In this embodiment, the operation units 222, 226, 228, and 232, which will be described later, correspond to the input interface 313.

[0024] The output interface 314 functions as an output unit for outputting various information received from the terminal device 200, etc. An example of the output interface 314 is a speaker for audio output, but it is not limited to this and may consist of a display, another liquid crystal panel, an organic EL display, a plasma display, a light-emitting device such as an LED, a vibration device, a printer, etc. Furthermore, it is not necessary for a speaker to be provided; for example, an interface for connecting to a speaker, etc. that can be connected to the terminal device 200 via a wired or wireless network can also function as the output interface 314 for outputting audio information data to the speaker, etc. In this embodiment, the illumination unit 214, the laser irradiation unit 216, and the audio output unit 234, which will be described later, correspond to the output interface 314.

[0025] The communication interface 315 functions as a communication unit for sending and receiving information with the server device 100, terminal device 200, and helmet mounting device 300. Examples of the communication interface 315 include wired communication connectors such as USB and SCSI, transceiver devices for broadband wireless communication such as wireless LAN, Bluetooth®, and LTE, short-range or contactless wireless communication such as infrared and NFC, and various connection terminals for printed circuit boards and flexible circuit boards. In this embodiment, the communication interface 315 uses a wireless network. In this embodiment, the communication unit 236, which will be described later, corresponds to the communication interface 315.

[0026] Sensor 316 functions as an information acquisition unit for acquiring image information, etc. Examples of sensors 316 include cameras (e.g., stereo cameras), distance measuring sensors, ultrasonic sensors, infrared sensors, ultraviolet sensors, proximity sensors, various radar sensors, and photoelectric sensors. Sensor 316 does not need to be constantly connected to the helmet mounting device 300; it may be connected to the helmet mounting device 300 via a wired or wireless communication network. This configuration increases the flexibility of where the sensor 316 can be used. In this embodiment, the image information acquisition unit 212, which will be described later, corresponds to sensor 316.

[0027] Figure 2 shows an example of the configuration of a helmet mounting device 300 according to one embodiment of the present invention. The helmet mounting device 300 in this example comprises a first module 210, a second module 220, a third module 230, a fourth module 240, and a frame 250. The helmet mounting device 300 in this example is attached to a helmet. By being attached to a helmet, the helmet mounting device 300 in this example functions as a wearable device. Since the helmet mounting device 300 is communicably connected to other terminal devices via a communication line 30, the user can make calls and communicate with an administrator via the helmet mounting device 300. The helmet mounting device 300 in this example can also be attached directly to the user's head without being attached to a helmet, and the helmet mounting device 300 can function as a wearable device on its own.

[0028] The first module 210 of the helmet mounting device 300 acquires surrounding image information. Here, Figure 3 is a front view showing an example of the configuration of the helmet mounting device 300 according to one embodiment of the present invention. Figure 3 is a view of the helmet mounting device 300 from the negative side in the Y-axis direction. The first module 210 includes an image information acquisition unit 212, an illumination unit 214, a laser irradiation unit 216, an angle adjustment unit 218, an operation unit 222, and a mounting device 224. The first module 210 may also include other components. In Figure 3, the second module 220 is provided on the negative side in the X-axis direction. In Figure 3, the third module 230 is provided on the positive side in the X-axis direction.

[0029] In Figure 3, the image information acquisition unit 212 is a roughly circular area. The image information acquisition unit 212 is positioned in the first module 210, which is installed on the outer circumference of the frame 250, so as to face outwards from the frame 250. The image information acquisition unit 212 is also positioned adjacent to the illumination unit 214 and the laser irradiation unit 216 in the angle adjustment unit 218. In this example, the illumination unit 214, the laser irradiation unit 216, and the image information acquisition unit 212 are arranged in order from the negative side of the X-axis direction. The image information acquisition unit 212 is also positioned approximately in the center of the first module 210 in the Z-axis direction (height direction).

[0030] The image information acquisition unit 212 is, for example, a camera. The image information acquisition unit 212 can utilize any known technology such as a CMOS (Complementary Metal-Oxide-Semiconductor) camera or a CCD (Charge Coupled Device) camera. The image information acquisition unit 212 may include an image sensor.

[0031] The image information acquisition unit 212 starts up when the power supply unit 238 (described later) is activated and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 is activated, the image information acquisition unit 212 also starts up. Alternatively, a separate power supply button may be provided, and the image information acquisition unit 212 may start up when this power supply button is operated (pressed down).

[0032] After power is supplied, the image information acquisition unit 212 acquires image information when the operation unit 228, which will be described later, is operated. The image information acquired by the image information acquisition unit 212 may include information about one or more still images. The image information acquired by the image information acquisition unit 212 may include information about multiple images, for example, information about a video. The image information is, as an example, information about a color image, but it can also include information about various other images such as black and white images, infrared images, ultraviolet images, point cloud images, X-ray images, thermal images, multispectral images, hyperspectral images, MRI images, etc. In this example, the image information includes information about images of tools and other objects to be operated, building products, and workers at the work site.

[0033] The image information acquisition unit 212 transmits the acquired image information to the memory 312. The memory 312 may store the acquired image information. The communication unit 236, which will be described later, may transmit the image information to the terminal device 200. The process of storing the image information in the memory 312 and the process of transmitting the image information to the terminal device 200 may be performed automatically or in response to a predetermined operation.

[0034] Based on the above, the image information acquisition unit 212 acquires image information of the area around the helmet mounting device. The image information acquisition unit 212 may acquire images in the direction of the user's line of sight. The direction of the user's line of sight is the direction in front of the user. Since the first module 210 includes the image information acquisition unit 212, it can transmit image information in the direction of the user's line of sight to the terminal device 200. Then, on the terminal device 200, the administrator can check the situation around the user.

[0035] In Figure 3, the illumination unit 214 is a roughly circular area. The illumination unit 214 is positioned in the first module 210, which is installed on the outer circumference of the frame 250, so as to face outwards from the frame 250. The illumination unit 214 is also positioned adjacent to the image information acquisition unit 212 and the laser irradiation unit 216 in the angle adjustment unit 218. Furthermore, the illumination unit 214 is positioned approximately in the center of the first module 210 in the Z-axis direction (height direction).

[0036] The lighting unit 214 can utilize a light source that enhances user visibility by emitting light. The lighting unit 214 can utilize any known technology such as lamps, arc lamps, lights, and LEDs (Light-Emitting Diodes).

[0037] The lighting unit 214 starts up when the power supply unit 238 is activated and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 is activated, the lighting unit 214 also starts up. Alternatively, a separate power supply button may be provided, and the lighting unit 214 may start up when this power supply button is operated (pressed down).

[0038] After power is supplied, the lighting unit 214 turns on the lights when the operation unit 222 is operated. Alternatively, the lighting unit 214 may turn on the lights when the power supply unit 238 is started up. In this case, the lighting unit 214 turns off the lights when the operation unit 222 is operated. If the operation unit 222 is operated, the lighting unit 214 may turn on the lights.

[0039] As described above, the lighting unit 214 emits light around the helmet mounting device. The lighting unit 214 may emit light in the user's line of sight. Since the first module 210 includes the lighting unit 214, the user can turn on the lights and work safely.

[0040] In Figure 3, the laser irradiation unit 216 is a roughly circular area. The laser irradiation unit 216 is positioned in the first module 210, which is installed on the outer circumference of the frame 250, so as to face outwards from the frame 250. The laser irradiation unit 216 is also positioned adjacent to the image information acquisition unit 212 and the laser irradiation unit 216 in the angle adjustment unit 218. Furthermore, the laser irradiation unit 216 is positioned approximately in the center of the first module 210 in the Z-axis direction (height direction).

[0041] The laser irradiation unit 216 can utilize a highly directional laser light source. The laser irradiation unit 216 can utilize any known technology such as a laser pointer (red laser, green laser, blue laser, etc.). The laser irradiation unit 216 may include an optical system such as a laser oscillator and lenses that generate light. The laser irradiation unit 216 may be a semiconductor laser.

[0042] The laser irradiation unit 216 starts up when the power supply unit 238 is activated and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 is activated, the laser irradiation unit 216 also starts up. Alternatively, a separate power supply button may be provided, and the laser irradiation unit 216 may start up when this power supply button is operated (pressed down).

[0043] The laser irradiation unit 216 emits laser light upon operation by the administrator. The laser irradiation unit 216 generates laser light using a laser oscillator and amplifies it using an optical system such as a lens. In other words, when the communication unit 236 receives confirmation that the administrator has performed a predetermined operation on the terminal device 200, the laser irradiation unit 216 emits laser light. Alternatively, if an operation unit such as the image information acquisition unit 212 or the illumination unit 214 is provided, the laser irradiation unit 216 may emit laser light when the operation unit is operated by the user.

[0044] The laser irradiation unit 216 irradiates laser light around the helmet wearing device. The laser irradiation unit 216 irradiates laser light onto an object in the user's line of sight. Since the laser irradiation unit 216 can be operated in the terminal device 200, the administrator can accurately send instructions to the user through the irradiation of the laser light. In addition, since the image information acquisition unit 212 acquires image information related to the object irradiated with the laser light, the administrator can confirm the direction of the user's line of sight and accurately send instructions to the user.

[0045] In addition, the image information acquisition unit 212 may automatically perform calibration to align the laser optical axis of the laser irradiation unit 216 with the optical axis of the image information acquisition unit 212. Specifically, the calibration performed by the image information acquisition unit 212 refers to correcting and trimming the image information acquired by the image information acquisition unit 212 so that the laser light is centered in the image information. Further, the calibration may also refer to mechanically adjusting the laser optical axis of the laser irradiation unit 216 or the optical axis of the image information acquisition unit 212 so that the laser light is centered in the image information acquired by the image information acquisition unit 212.

[0046] Furthermore, the image information acquisition unit 212 may correct and trim the image information acquired by the image information acquisition unit 212. For example, the image information acquisition unit 212 may correct and trim the image information acquired by the image information acquisition unit 212 so that an object (for example, the laser light irradiated by the laser irradiation unit 216) is enlarged in the image information. When the object is moving, a tracking image can be acquired by correcting and trimming the image information to enlarge the object and acquiring the image information continuously.

[0047] In FIG. 3, the angle adjustment unit 218 is a rectangular area (plate-shaped member). The angle adjustment unit 218 is arranged substantially at the center of the first module 210 in the Z-axis direction (height direction). The angle adjustment unit 218 is provided with an image information acquisition unit 212, an illumination unit 214, and a laser irradiation unit 216. In this example, the angle adjustment unit 218 has a configuration in which a rotating shaft is provided on the plate-shaped member. One end of the plate-shaped member in the longitudinal direction of the angle adjustment unit 218 is connected to a frame 250 via the rotating shaft, so that the angle of the plate-shaped member relative to the Y-axis direction about the rotating shaft can be adjusted.

[0048] Therefore, by adjusting the angle of the angle adjustment unit 218, a user can adjust the image acquisition direction (image angle of view) of the image information acquisition unit 212 and the laser light irradiation direction of the laser irradiation unit 216. When the illumination unit 214 is a directional light source, the light emission direction of the illumination unit 214 may also be adjustable. As an example, in the angle adjustment unit 218, the angle is adjusted such that the image acquisition direction and the laser light irradiation direction of the laser irradiation unit 216 form an angle of ±30 degrees with respect to the Y-axis direction. In this case, the angle may be adjusted in three steps in the angle adjustment unit 218 such that the image acquisition direction and the laser light irradiation direction of the laser irradiation unit 216 form angles of +30 degrees, 0 degrees, and -30 degrees with respect to the Y-axis direction. Furthermore, in the angle adjustment unit 218, the angle may be continuously adjusted such that the image acquisition direction and the laser light irradiation direction of the laser irradiation unit 216 form an angle within a range of ±30 degrees with respect to the Y-axis direction.

[0049] In FIG. 3, the operation unit 222 is a button-shaped region. The operation unit 222 is provided on a side surface of the first module 210 in FIG. 3. In this example, the operation unit 222 is provided to face the negative side in the X-axis direction. The operation unit 222 is arranged substantially at the center of the first module 210 in the Z-axis direction (height direction).

[0050] The operation unit 222 is provided on the first module 210 so as to be operable by the user. The operation unit 222 may be, for example, a physical key button and may be pressable. In this example, the operation unit 222 is pressable down on the positive side of the X axis. As mentioned above, the operation unit 222 is not limited to a physical key button. The operation unit 222 may be a microphone. In this case, the operation unit 222 may be considered operated when a predetermined sound is input to the operation unit 222. Alternatively, the operation unit 222 may be considered operated when a predetermined sound is input to the voice information acquisition unit 225.

[0051] When the operation unit 222 is operated (when a physical key button is pressed), the operation unit 222 may transmit information that the operation has been performed to the lighting unit 214 in the form of an electrical signal. When the lighting unit 214 receives information that the operation has been performed, the lighting unit 214 turns on the lights.

[0052] Furthermore, when the operation unit 222 is operated, the illumination unit 214 may switch the illumination on or off. Also, when the operation unit 222 is operated, the laser irradiation unit 216 may irradiate laser light. Also, when the operation unit 222 is operated, the irradiation of laser light may be switched on or off. Since the illumination unit 214 and the operation unit 222 used to operate the illumination unit 214 are located in the first module 210, the user can easily turn on the illumination.

[0053] In Figure 3, the mounting bracket 224 is provided on the lower surface of the first module 210. The mounting bracket 224 has a somewhat movable structure, such as a belt. The mounting bracket 224 may be provided with a length adjustment section, allowing the overall length of the mounting bracket 224 to be adjusted.

[0054] The mounting bracket 224 is used by the user to attach the helmet mounting device 300 to the helmet by fixing the mounting bracket 224 to the helmet. The mounting bracket 224 is, for example, a mounting fitting such as a hook. The mounting bracket 224 may also be double-sided tape.

[0055] The second module 220 includes an audio information acquisition unit 225 that acquires audio information from around the helmet mounting device 300. Here, Figure 4 is a side view showing an example of the configuration of the helmet mounting device 300 according to one embodiment of the present invention. Figure 4 is a view of the helmet mounting device 300 from the negative side in the X-axis direction. The second module 220 includes an audio information acquisition unit 225, an operation unit 226, an operation unit 228, and an operation unit 232. The second module 220 may also include other components. In Figure 4, the first module 210 is provided on the negative side in the Y-axis direction. In Figure 4, the fourth module 240 is provided on the positive side in the Y-axis direction. As shown in Figure 3, the second module 220 is arranged at a substantially inclined (tapered) angle with respect to the Z-axis direction. Because the second module 220 is arranged at a substantially inclined angle with respect to the Z-axis direction, the helmet mounting device 300 is easier to attach to the helmet.

[0056] In Figure 4, the voice information acquisition unit 225 is a rectangular area. In this example, the voice information acquisition unit 225 is located on the negative side of the Y-axis in the second module 220. Because the voice information acquisition unit 225 is located on the negative side of the Y-axis in the second module 220, the voice information acquisition unit 225 is close to the user's mouth, allowing the voice information acquisition unit 225 to efficiently acquire voice information. In this example, the voice information acquisition unit 225 is exposed to the outside of the housing of the second module 220, but the voice information acquisition unit 225 may also be located inside the housing of the second module 220.

[0057] The audio information acquisition unit 225 may have a structure that converts the acquired audio into audio information in the form of an electrical signal. The audio information acquisition unit 225 is, for example, a microphone, and various structures such as a condenser microphone, dynamic microphone, or ribbon microphone can be used.

[0058] The voice information acquisition unit 225 starts up when the power supply unit 238 is activated and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 is activated, the voice information acquisition unit 225 also starts up. Alternatively, a separate power supply button may be provided, and the image information acquisition unit 212 may start up when this power supply button is operated (pressed down).

[0059] After power is supplied, the voice information acquisition unit 225 acquires voice information. In this example, after power is supplied, the voice information acquisition unit 225 automatically acquires voice information. Alternatively, if an operating unit such as the image information acquisition unit 212 or the lighting unit 214 is provided and the operating unit is operated by the user, the voice information acquisition unit 225 may acquire voice information. The voice information acquired by the voice information acquisition unit 225 is voice information relating to the user's own voice. However, the voice information acquired by the voice information acquisition unit 225 is not limited to this, and may also acquire voice information relating to sounds at the work site, etc.

[0060] The voice information acquisition unit 225 transmits the acquired voice information to the memory 312. The memory 312 may store the acquired voice information. The communication unit 236 may also transmit the voice information to the terminal device 200. The process of storing the voice information in the memory 312 and the process of transmitting the voice information to the terminal device 200 may be performed automatically or in response to a predetermined operation. Any storage format can be used for the voice information, such as WAV, MP3, AAC, FLAC, ALAC, etc.

[0061] The voice information acquisition unit 225 acquires voice information from the area around the helmet mounting device 300. The voice information acquisition unit 225 may convert the voice into voice information in the form of electrical signals. Because the voice information acquisition unit 225 is provided, the user can transmit voice information about their own voice to the terminal device 200 and converse with the administrator via the terminal device 200.

[0062] In Figure 4, the operating section 226 is a button-shaped area. The operating section 226 is located on the front of the second module 220 in Figure 4. In this example, the operating section 226 is positioned to face the negative side of the X-axis direction. The operating section 226 is also positioned approximately in the center of the second module 220 in the Z-axis direction (height direction). The operating section 226 is also positioned approximately in the center of the second module 220 in the Y-axis direction.

[0063] The operation unit 226 is provided on the second module 220 so as to be operable by the user. The operation unit 226 may be, for example, a physical key button and may be pressable. In this example, the operation unit 222 can be pushed down in the positive direction of the X axis. As mentioned above, the operation unit 226 is not limited to a physical key button. The operation unit 226 may be a microphone. In this case, the operation unit 226 may be considered operated when a predetermined sound is input to it. Alternatively, the operation unit 226 may be considered operated when a predetermined sound is input to the voice information acquisition unit 225.

[0064] When the operation unit 226 is operated (when a physical key button is pressed down), the operation unit 226 may transmit information that the operation has been performed to the communication unit 236 in the form of an electrical signal. When the communication unit 236 receives information that the operation has been performed, the communication unit 236 transmits information that the operation unit 226 has been operated to a predetermined terminal device (terminal device 200, etc.).

[0065] The control unit 226 can be used, for example, as an SOS button. By notifying a designated terminal device (the administrator's terminal device) that the button has been pressed, the user's administrator can be informed that the user is in a dangerous situation, which is useful in ensuring the user's safety.

[0066] In Figure 4, the operating section 228 is a button-shaped area. The operating section 228 is located on the upper surface of the second module 220 in Figure 4. In this example, the operating section 228 is positioned to face the positive side of the Z-axis direction. The operating section 228 is also positioned approximately in the center of the second module 220 in the Y-axis direction.

[0067] The operation unit 228 is provided on the second module 220 so as to be operable by the user. The operation unit 228 may be, for example, a physical key button and may be pressable. In this example, the operation unit 228 is pressable down on the negative side of the Z-axis direction. As mentioned above, the operation unit 228 is not limited to a physical key button. The operation unit 228 may be a microphone. In this case, the operation unit 228 may be considered operated when a predetermined sound is input to it. Alternatively, the operation unit 228 may be considered operated when a predetermined sound is input to the voice information acquisition unit 225.

[0068] When the operation unit 228 is operated (when a physical key button is pressed), the operation unit 228 may transmit information that the operation has been performed to the image information acquisition unit 212 in the form of an electrical signal. When the image information acquisition unit 212 receives information that the operation has been performed, the image information acquisition unit 212 acquires predetermined image information.

[0069] Here, the image information acquisition unit 212 is provided in the first module 210, and the operation unit 228 is provided in the second module 220. The operation unit 228 is provided in the second module 220, which is easier to operate with the right hand, and by operating the operation unit 228, the image information acquisition unit 212 in the first module 210, which is located in front of the user, can be operated, making it possible for the user to easily acquire images.

[0070] In Figure 4, the operating section 232 is a button-shaped area. The operating section 232 is located on the side of the second module 220 in Figure 4. In this example, the operating section 232 is positioned to face the positive side in the Y-axis direction. The operating section 232 is also positioned approximately in the center of the second module 220 in the Z-axis direction (height direction).

[0071] The operation unit 232 is provided on the second module 220 so as to be operable by the user. The operation unit 232 may be, for example, a physical key button and may be pressable. In this example, the operation unit 232 is pressable down on the negative side of the Y-axis. As mentioned above, the operation unit 232 is not limited to a physical key button. The operation unit 232 may be a microphone. In this case, the operation unit 232 may be considered operated when a predetermined sound is input to it. Alternatively, the operation unit 232 may be considered operated when a predetermined sound is input to the voice information acquisition unit 225.

[0072] When the operation unit 232 is operated (when a physical key button is pressed), the operation unit 232 may transmit information that the operation has been performed to the power supply unit 238 in the form of an electrical signal. When the power supply unit 238 receives information that the operation has been performed, the power supply unit 238 may be activated. In other words, when the power supply unit 238 receives information that the operation has been performed, the power supply unit 238 may start supplying power to the image information acquisition unit 212, etc. In other words, when the operation unit 232 is operated, the power supply unit 238 may be switched on or off.

[0073] Here, the power supply unit 238 is provided in the fourth module 240, and the operation unit 232 is provided in the second module 220. The operation unit 232 is provided in the second module 220, which is easier to operate with the right hand, and the power supply unit 238 of the fourth module 240, which is located on the back, can be operated by operating the operation unit 232, so the user can easily switch the power supply unit 238 on or off.

[0074] The third module 230 includes an audio output unit 234 that outputs audio acquired from the server device 100. Here, Figure 5 is a side view showing an example of the configuration of a helmet mounting device 300 according to one embodiment of the present invention. Figure 5 is a view of the helmet mounting device 300 from the positive side in the X-axis direction. The third module 230 includes an audio output unit 234 and a communication unit 236. The third module 230 may also include other components. In Figure 5, the first module 210 is provided on the negative side in the Y-axis direction. In Figure 5, the fourth module 240 is provided on the positive side in the Y-axis direction. As shown in Figure 3, the third module 230 is arranged at a substantially inclination with respect to the Z-axis direction. Because the third module 230 is arranged at a substantially inclination with respect to the Z-axis direction, the helmet mounting device 300 is easier to attach to the helmet.

[0075] In Figure 5, the audio output unit 234 is a rectangular area. In this example, the audio output unit 234 is located on the negative side of the Y-axis direction in the third module 230. In this example, the audio output unit 234 is exposed to the outside of the housing of the third module 230, but the audio output unit 234 may also be located inside the housing of the third module 230.

[0076] The audio output unit 234 may have a structure that converts acquired audio information (electrical signals) into audio. The audio output unit 234 is, for example, a speaker, and various structures such as dynamic speakers, condenser speakers, and piezoelectric speakers can be used.

[0077] The audio output unit 234 starts up when the power supply unit 238 is activated and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 is activated, the audio output unit 234 also starts up. Alternatively, a separate power supply button may be provided, and the audio output unit 234 may start up when this power supply button is operated (pressed down).

[0078] After power is supplied, the audio output unit 234 outputs audio. In this example, the audio output unit 234 outputs audio based on audio information received by the communication unit 236 via the server device. The audio information received by the communication unit 236 is, for example, audio information related to audio acquired by the terminal device 200. The audio information received by the communication unit 236 is, for example, audio information related to audio acquired by a microphone provided on the terminal device 200. In this example, the audio information received by the communication unit 236 is audio information related to audio spoken by the administrator. After power is supplied, if the communication unit 236 receives audio information, the audio output unit 234 may automatically output audio. Alternatively, after power is supplied, if the communication unit 236 receives audio information and a predetermined operation is performed, the audio output unit 234 may output audio. This predetermined operation may be an operation by a user or an operation by an administrator (an operation from the terminal device 200).

[0079] The audio output unit 234 outputs audio acquired from the server device via the communication unit 236. The audio output unit 234 can output audio based on audio information (a predetermined electrical signal) acquired from the server device via the communication unit 236. Because the audio output unit 234 is provided, if the audio information received by the communication unit 236 is audio information related to audio spoken by the administrator, it can output audio based on the audio information received from the terminal device 200, and the user can converse with the administrator via the helmet attachment 300.

[0080] In Figure 5, the communication unit 236 is a rectangular area. In this example, the communication unit 236 is located approximately in the center of the third module 230 in the Y-axis direction. In this example, the communication unit 236 is exposed to the outside of the housing of the third module 230, but the communication unit 236 may also be located inside the housing of the third module 230.

[0081] Examples of the communication section 236 include a variety of devices such as wireless LAN, Bluetooth®, LTE and other broadband wireless communication devices, infrared and other wireless communication transceivers, and various connection terminals for printed circuit boards and flexible circuit boards.

[0082] The communication unit 236 starts up when the power supply unit 238 is started and power is supplied from the power supply unit 238. In other words, when the power supply unit 238 starts up, the communication unit 236 also starts up. Alternatively, a separate power supply button may be provided, and the communication unit 236 may start up when this power supply button is operated (pressed down).

[0083] The communication unit 236 transmits and receives various information with the server device 100, which is connected via a wireless network. For example, the communication unit 236 receives audio information used in the audio output unit 234 from the terminal device 200. The communication unit 236 transmits the received audio information to the audio output unit 234. The communication unit 236 also transmits image information acquired by the image information acquisition unit 212 or audio information acquired by the audio information acquisition unit 225 to the terminal device 200. Therefore, the user can share images and audio and communicate with the administrator via the helmet mounting device 300.

[0084] The fourth module 240 includes a power supply unit 238 that supplies power to at least one of the image information acquisition unit 212, the audio information acquisition unit 225, and the audio output unit 234. Here, Figure 6 is a rear view showing an example of the configuration of a helmet mounting device 300 according to one embodiment of the present invention. Figure 6 is a view of the helmet mounting device 300 from the positive side in the Y-axis direction. The fourth module 240 includes a power supply unit 238, an adjustment unit 242, and a mounting device 244. The fourth module 240 may also include other components. In Figure 6, the second module 220 is provided on the negative side in the X-axis direction. In Figure 6, the third module 230 is provided on the positive side in the X-axis direction. As shown in Figure 6, the second module 220 and the third module 230 are arranged at a substantially inclined angle with respect to the Z-axis direction.

[0085] In Figure 6, the power supply unit 238 is located inside the housing of the fourth module 240. Alternatively, the power supply unit 238 may be located outside the housing of the fourth module 240. The power supply unit 238 only needs to have a structure that can supply a predetermined power supply. The power supply unit 238 may include a rechargeable battery or the like. The power supply unit 238 may utilize any known technology such as a switching power supply or a converter. The power supply unit 238 may be powered from an external source and supplied with power to at least one of the image information acquisition unit 212, the audio information acquisition unit 225, and the audio output unit 234. The power supply unit 238 may also be a connector or the like.

[0086] When the operation unit 232 is operated (when a physical key button is pressed), the power supply unit 238 supplies power to at least one of the image information acquisition unit 212, the audio information acquisition unit 225, and the audio output unit 234. In this example, the power supply unit 238 supplies power to the image information acquisition unit 212, the audio information acquisition unit 225, and the audio output unit 234. Furthermore, the power supply unit 238 may also supply power to the illumination unit 214, the laser irradiation unit 216, and the communication unit 236. By providing the power supply unit 238, power can be supplied to the image information acquisition unit 212, the audio information acquisition unit 225, and the audio output unit 234.

[0087] In Figure 6, the adjustment unit 242 is provided on the front of the fourth module 240. The adjustment unit 242 is positioned approximately in the center of the fourth module 240 in the Z-axis direction (height direction). The adjustment unit 242 is positioned approximately in the center of the fourth module 240 in the X-axis direction. Note that if the helmet attachment 300 functions as a wearable device on its own, the fourth module 240 does not need to include the adjustment unit 242.

[0088] The adjustment unit 242 adjusts the length of the frame 250. The length of the frame 250 is adjusted by the user rotating the adjustment unit 242. The adjustment unit 242 may be a dial button.

[0089] In Figure 6, the mounting bracket 244 is provided on the lower surface of the fourth module 240. The mounting bracket 244 has a somewhat movable structure, such as a belt. The mounting bracket 244 may also be provided with a length adjustment section, allowing the overall length of the mounting bracket 224 to be adjusted. In this example, the mounting bracket 244 does not include a length adjustment section.

[0090] The mounting bracket 244 is used by the user to attach the helmet mounting device 300 to the helmet by fixing the mounting bracket 244 to the helmet. The mounting bracket 244 is, for example, a mounting fitting such as a hook. The mounting bracket 244 may also be double-sided tape.

[0091] As described above, since the helmet mounting device 300, which can be attached to a helmet, comprises a first module 210, a second module 220, a third module 230, and a fourth module 240, when the helmet mounting device 300 is attached to a helmet, the user can easily make calls and communicate with the administrator via the helmet mounting device 300.

[0092] Figure 7 is a top view showing an example of the configuration of a helmet mounting device 300 according to one embodiment of the present invention. Figure 7 is a view of the helmet mounting device 300 from the positive Z-axis side. Figure 8 is a bottom view showing an example of the configuration of a helmet mounting device 300 according to one embodiment of the present invention. Figure 8 is a view of the helmet mounting device 300 from the negative Z-axis side. In Figures 7 and 8, the first module 210 and the fourth module 240 are arranged side by side in the Y-axis direction. In Figures 7 and 8, the second module 220 and the third module 230 are arranged side by side in the X-axis direction.

[0093] In Figures 7 and 8, the frame 250 has a first module 210, a second module 220, a third module 230, and a fourth module 240 arranged on it. The frame 250 also has a circular shape when viewed from above and below. Because the frame 250 has a circular shape, it is easy to attach the helmet mount 300 to the helmet and prevents the helmet mount 300 from separating from the helmet. The frame 250 may also be made of a deformable material such as a spring or plastic. Because the frame 250 is made of a deformable material, it is easy to attach to the helmet.

[0094] In this example, the first module 210 and the fourth module 240 are positioned opposite each other in the Y-axis direction with respect to the approximate center of the frame 250. Furthermore, in this example, the second module 220 and the third module 230 are positioned opposite each other in the X-axis direction with respect to the approximate center C of the frame 250. The center C of the frame 250 is the center in the XY plane and may coincide with the center of gravity of the frame 250. With this configuration, the centers of gravity of the helmet and the helmet mounting device 300 can be aligned, thereby reducing the burden on the user.

[0095] Furthermore, it is preferable that the weights of the first module 210, the second module 220, the third module 230, and the fourth module 240 be approximately the same. For example, the weight of the first module 210 may be within ±5% of the weights of the second module 220, the third module 230, and the fourth module 240. The weight of the first module 210 may be within ±10% of the weights of the second module 220, the third module 230, and the fourth module 240. The weight of the first module 210 may be within ±15% of the weights of the second module 220, the third module 230, and the fourth module 240. The weight of the first module 210 may be within ±20% of the weights of the second module 220, the third module 230, and the fourth module 240. Since the weights of the first module 210, the second module 220, the third module 230, and the fourth module 240 are approximately the same, the center of gravity of the helmet and the helmet mounting device 300 can be aligned, thereby reducing the burden on the user.

[0096] Furthermore, in Figures 7 and 8, at least a portion of the fourth module 240 may be positioned inside the frame 250. The first module 210, the second module 220, and the third module 230 may be positioned outside the frame 250. In other words, the fourth module 240 may be positioned closer to the center C of the frame 250 compared to the first module 210, the second module 220, and the third module 230. By positioning at least a portion of the fourth module 240 inside the frame 250, the fourth module 240 can come into contact with the helmet when the helmet mounting device 300 is attached to the helmet. Therefore, the helmet mounting device 300 can be firmly fixed to the helmet.

[0097] In Figures 7 and 8, the power supply unit 238 and the adjustment unit 242 are provided in one fourth module 240. Also in Figures 7 and 8, the power supply unit 238 may be located inside the frame 250. In Figures 7 and 8, the adjustment unit 242 may be located outside the frame 250. In other words, the power supply unit 238 may be located closer to the approximate center C of the frame 250 compared to the adjustment unit 242. If the power supply unit 238 is located outside the frame 250, it will be necessary to make the power supply unit 238 a hollow structure in order to accommodate the adjustment unit 242, which will require special processing and make it difficult to manufacture the fourth module 240. By arranging the power supply unit 238 inside the frame 250 and the adjustment unit 242 outside the frame 250, the fourth module 240 can be manufactured simply.

[0098] The fourth module 240 may also include a contact detection unit (not shown) that detects contact with the helmet. The contact detection unit is, for example, button-shaped, and when it comes into contact with the helmet, the button is pressed down. Because the contact detection unit detects contact with the helmet, it can detect when the helmet mounting device 300 separates from the helmet (when the helmet is removed). When the helmet mounting device 300 separates from the helmet, the communication unit 236 provided in the third module 230 transmits information that the helmet mounting device 300 has separated from the helmet to a predetermined terminal device. Therefore, by informing the predetermined terminal device that the helmet mounting device 300 has separated from the helmet, it is possible to inform the user's administrator that the user is in a dangerous situation, which is useful in ensuring the user's safety.

[0099] Figures 9 and 10 show an example of the configuration of a wearable device 500 according to one embodiment of the present invention. The wearable device 500 includes a helmet mount 300 and a helmet 400. The wearable device 500 can function by attaching the helmet mount 300 described herein to the helmet 400.

[0100] In Figure 9, the mounting fixture 224 of the first module 210 includes a length adjustment section 246 whose length can be adjusted according to at least one of the size and shape of the helmet 400. The length adjustment section 246 allows the length of the mounting fixture 224 to be adjusted. By providing the length adjustment section 246, the helmet mounting fixture 300 can be firmly fixed to the helmet 400. In this example, the mounting fixture 244 of the fourth module 240 does not include a length adjustment section, but the mounting fixture 244 of the fourth module 240 may also include a length adjustment section.

[0101] The length adjustment section 246 may include a buckle. The buckle may also include a button. The length of the belt portion of the attachment 224 may be adjustable by pressing down the button on the buckle. When the button on the buckle is not pressed, the length of the belt portion of the attachment 224 is fixed.
