Description

TECHNICAL FIELD The present invention relates to an auditory wearable device management system, an auditory wearable device management method, and an auditory wearable device management program. The present invention relates to an auditory wearable device management system, an auditory wearable device management method, and an auditory wearable device management program.

Hearing wearable devices (hereinafter abbreviated as "hearing devices") are easier to wear than visual devices used in AR (Augmented Reality) and VR (Virtual Reality), and are used in fire fighting. It is also easy to lend and borrow hearing devices and change wearers at sites such as rescue, defense, and construction. Furthermore, the hearing device can be used in situations where visual obstruction would make the use of a visual device difficult. Hearing devices have such useful properties.

On the other hand, once a visual device or the like is worn, it remains almost in the state of being worn. However, due to the ease of wearing the device, lending and borrowing of the device at the site, and the ease of changing the wearer, it is not easy to statically estimate the wearer from the hearing device. You have to think of your relationship with devices as fluid.

Such characteristics of hearing devices become particularly noticeable when the hearing devices are shared by a group of a certain number of people. Also, when wearing a hearing device, rather than having each person find and wear their own hearing device, one or two hearing devices are randomly selected from a group of randomly placed hearing devices. It is often preferable to be in a situation where it is permissible to select and wear

Furthermore, when considering sites such as firefighting, rescue, defense, and construction, the possibility of exchanges of hearing devices between wearers in order to deal with malfunctions of hearing devices should be fully considered. becomes necessary.

Also, in general, auditory devices have a relatively low ability to separate and transmit each piece of information, compared to visual devices and the like. However, assuming that they are acting in a group, the ability to simultaneously transmit information with multiple characteristics, such as information addressed to each individual, broadcast information to a group of wearers, and broadcast information to all members of the group. is required. Therefore, assuming that these pieces of information are presented to the hearing device at the same time, it is important that the hearing device has a means of identifying individual pieces of information.

As a technology related to such applications, Patent Document 1, Japanese Patent Publication No. 2017-528990, "Multiple Listening Environment Generation Techniques Via Hearing Devices," describes a situation in which many conversations are taking place. A technique for independently level-controlling conversations between the two is disclosed. In addition, International Publication No. 2017/061218 of Patent Document 2, "Sound output device, sound generation method and program", discloses a method of localizing a sound image (sound source) at an arbitrary position. In addition, Japanese Patent Laid-Open No. 2015-136100 of Patent Document 3, “Hearing Device with Selectable Perceptual Spatial Positioning of Sound Sources,” discloses that the position of a sound image (sound source) can be arbitrarily set so that audio information can be heard. is disclosed.

However, in the current technology related to the present invention such as Patent Document 1, the hearing device (auditory wearable device) is related to the function when the wearer is fixed and used alone. There is no consideration at all for a specific mechanism to appropriately support the operation of hearing devices when a group of people share and use hearing devices.

In other words, in order to enable effective use of a hearing device shared by a group of a certain number of people, it is necessary to associate the hearing device with the user (wearer) in advance, as described above. Furthermore, it is necessary to respond quickly and flexibly to situations such as exchanging hearing devices or changing wearing conditions at the site of operation. However, in the current state of the art, no specific technique for solving these problems has been presented. In other words, in the current technology, in a situation where a large amount of audio information is multiplexed and transmitted, each wearer can wear any hearing device out of a plurality of shared hearing devices. It does not have a mechanism that makes it possible to accurately acquire the directed voice information.

The reason is that, instead of specifying a hearing device to provide audio information, a wearer is specified and audio information is provided to the hearing device that the wearer is wearing at that time. That is, the wearing information holding means controls the distributing operation of the audio information using the wearing information that associates (maps) the wearer and the hearing device as a key.

Second, each wearer is able to distinguish between different audio information even when multiple audio information is delivered. The reason for this is that not only the attributes (position, frequency, etc.) of the information sound source that is the source of the audio information, but also the hearing device that is worn by the wearer to whom the audio information is distributed. Since the wearer's sound field forming means for forming a sound field of information is provided, the wearing of the hearing device is determined by whether the wearer at the distribution destination wears the hearing device on both ears or on either the left or right ear. This is because a sound field suitable for each situation can be formed.

FIG. 1 is a system configuration diagram showing an example of the system configuration of a hearing wearable device management system according to the present invention. An example of a system configuration for support management is shown.

A hearing wearable device management system 100 shown in FIG. 4. One or a plurality of wearer information selection means 5, voice information distribution control means 6, information distribution means 7, and wearer group management means 8, which provide various voice information to each wearer. An information sound source 20 is provided.

Each of the plurality of hearing devices 10 has a function of determining whether or not its own device is in a worn state, and in the present embodiment, when it is in a worn state, it identifies the wearer who is wearing it. It also has a function of acquiring identification information. Then, when it is determined that the hearing device 10 is worn, the hearing device 10 transmits the identification information to the wearer identification means 1 .

Based on the identification information transmitted from each hearing device 10, the wearer identifying means 1 determines who the wearer is and whether the wearer is wearing the right ear or the left ear. Then, the discriminated information is stored in the wearing information holding means 2 as wearing information about the hearing device 10 worn.

In the present embodiment, regarding the identification information for identifying the wearer by the hearing device 10, the biological information of the wearer collected by the hearing device 10 (for example, orientation and movement of the ears and head, blood flow, ear holes, etc.) information such as shape). However, not from the hearing device 10, but in the wearer identification means 1, the wearer authentication means by means of voice recognition means, login information using voice, etc., and some operation for determining the wearing situation (for example, the hearing device 10 The identification information may be acquired based on an operation such as removing the . Furthermore, the information acquired by the voice recognition means, the wearer authentication means, etc. may be used together with the biometric information.

The information sound source 20 is a sound source that outputs various audio information that can be presented to the wearer of the hearing device 10 . In addition, the voice information distribution control means 6 determines to which wearer in the group the voice information of which information sound source out of the one or more information sound sources 20 is to be distributed, from the commander or the like of the group. Control based on instructions. Then, the voice information distribution control means 6 outputs to the information distribution means 7 distribution control information specifying the wearer to whom the voice information of each information sound source 20 is to be distributed.

Based on the distribution control information from the voice information distribution control means 6, the information distribution means 7 selects the wearer to whom the voice information of each information sound source 20 is to be distributed, and distributes the voice information of the information sound source 20. Distribute to applicable wearers.

Here, the information distribution means 7 is typically implemented in the form of topics, channels, etc. based on the Publish-Subscribe model, and for each audio information (topic) of the information sound source 20, each audio Voice information is distributed in the form of data distribution to individual wearers, all wearers, and wearer groups set as target listeners (subscribers of the topic). The voice information for individual wearers and the voice information for broadcast to all wearers by the information distribution means 7 are sent to the wearer channel 7a. is once sent to the group channel 7b.

The voice information for the individual wearer by the information distribution means 7 is also controlled by the wearer information selection means 5 which can be specified by each wearer individually, and the voice information from the information distribution means 7 is sent. The wearer channel 7a to be received can be controlled by the wearer information selection means 5 to select voice information to be received for each individual wearer.

Further, the voice information for multi-addressing to the wearer group is once sent to the group channel 7b, the distribution destination is controlled by the wearer group management means 8, and the wearer who is a member of the wearer group is sent to the group channel 7b. It is set as voice information for broadcast addressed to each of them, and transferred to the wearer channel 7a. As a result, the voice information for multi-address is sent to all the members of the wearer group designated as the distribution destination of the multi-address. Here, the team organizer or the like in the group arbitrarily designates the members of the wearer group to whom the voice information of the information sound source 20 is to be broadcasted, and the wearer's group is equipped to manage the members of the wearer group. registered in the person group management means 8 in advance.

Returning to the description of FIG. 1, the wearer sound field forming means 3 converts the voice information distributed to the wearer to the voice information for the wearer sent to the wearer channel 7a as other voice information. The sound field is formed in a form that can be separated and identified, and the sound field localization, frequency, volume level, etc. are processed. In processing the voice information for the wearer, the wearer sound field forming means 3 processes the attributes (position, frequency, volume level, phase, etc.) of the information sound source 20 to be processed and the wearer's biological information. In addition, the wearing state of the hearing device 10, such as whether the wearer to whom the audio information is distributed wears the hearing device 10 in one ear or in both ears, is acquired from the wearing information holding means 2, and used for forming the sound field. I am using After finishing the processing of the voice information, the wearer sound field forming means 3 sends the processed voice information to the data distribution means 4 as processed data.

The data distributing means 4 distributes the processed data received from the wearer sound field forming means 3 to the hearing device 10 of the wearer designated as a distribution destination. Here, when the data distributing means 4 receives the processed data from the wearer sound field forming means 3, first, the data distributing means 4 accesses the wearing information holding means 2 holding the association between the wearer and the hearing device 10, and Acquires information about the hearing device 10 worn by the wearer designated as the distribution destination of the processed data received from the human sound field forming means 3 . Thereafter, the data distributing means 4 distributes the processed data received from the wearer sound field forming means 3 to the hearing device 10 worn by the wearer of the distribution destination.

(Explanation of the operation of the embodiment of the present invention)
Next, operation of the auditory wearable device management system 100 shown in FIG. 1 as one embodiment of the present invention will be described in detail.

When the wearer wears the hearing device 10 , information identifying the wearer is transmitted from the hearing device 10 to the wearer identification means 1 . Here, the transmitted information is the wearer's biological information collected by the hearing device 10, etc., as described above. Based on the information transmitted from the hearing device 10, the wearer identifying means 1 identifies the wearer and whether the hearing device 10 is worn on the wearer's right ear or left ear. Determine ear or both ears.

If such information cannot be acquired only from the wearer's biological information from the hearing device 10, as described above, user identification processing, login processing, etc. by voice, etc., and wearing state determination are performed. Depending on the procedure (such as removing the hearing devices 10 one by one), the biometric information may be substituted or used together with the biometric information.

Wearing information (wearer and wearing state of the hearing device 10) discriminated by the wearer identifying means 1 is held in the wearing information holding means 2, and information for sound source generation in the wearer sound field forming means 3 and data distributing means. 4 or the like is used as relationship determination information between the wearer and the hearing device 10 .

With such a configuration including the wearer identifying means 1 and the wearing information holding means 2, the relationship between the hearing device 10 and the wearer becomes fluid, and the wearing state of the hearing device 10 can be changed at the site of use. It is possible to flexibly and quickly respond to a change in the wearer of the hearing device 10 due to lending and borrowing.

The audio information presented to the wearer is audio information possessed by one or more information sound sources 20 . The information sound source 20 includes not only a guidance sound source that uses voice information accompanied by absolute position information for guidance, but also an information sound source that uses voice information not accompanied by absolute position information for providing information. can be Here, the guidance sound source is fixedly arranged at the position indicated by the absolute position information, and the fixed position is set and registered in advance as an attribute of the information sound source 20 . On the other hand, the position of the information sound source can be arranged at any position by the wearer, the commander of the group, the team organizer who manages the wearer group, etc., and the arranged position is the information sound source 20. It is set and registered as an attribute.

In addition, the commander of the group in the auditory wearable device management system 100 configures the group for each information sound source 20 in addition to the attributes indicating the position where each information sound source 20 is arranged and the attributes such as frequency and volume level. Voice information such as addressing individual wearers, broadcast to all members of wearer groups arbitrarily organized within the group by team organizers, etc., broadcast to all wearers making up the group, non-distribution, etc. Give attributes related to the distribution of The voice information of the information sound source 20 corresponding to the wearer channel 7a assigned to each wearer is distributed in accordance with the given distribution-related attribute.

Voice information addressed to all members of the wearer group is once distributed to the group channel 7b by the information distribution means 7. 7 a , and the same voice information is sent to each member (each wearer) of the wearer group designated by the wearer group management means 8 . Here, the team organizer of the wearer group can change the members of the wearer group by controlling the management information of the wearer group management means 8 (that is, the information about the members of the registered wearer group). You can deal with it flexibly.

The voice information sent to the wearer's channel 7a is processed into a form suitable for separate identification from other voice information by the wearer's sound field forming means 3 having an internal configuration as shown in FIG. . That is, the wearer's sound field forming means 3 not only attributes (position, frequency, volume level, phase, etc.) associated with the information sound source 20 that is the source of the target audio information and biological information of the wearer, According to the wearing status of the wearer indicated by the wearing information held in the wearing information held in the wearing information holding means 2 and the wearer indicating the distribution destination of the voice information specified by the distribution control information etc. from the information distribution control means 6, The audio information, which is the object of sound field formation, is processed into a form suitable for being separated from other audio information and identified. FIG. 2 is a block configuration diagram showing an example of the internal configuration of the wearer's sound field forming means 3 of the auditory wearable device management system 100 shown in FIG.

Here, as described above, the wearer's sound field forming means 3 controls the voice information distribution control means 6 and the wearer's information regarding the voice information of each of the plurality of information sound sources 20 (guidance sound sources and various information sound sources). It is means for forming a sound field processed into a format that can be identified by the wearer designated by the selection means 5, the wearer group management means 8, or the like. Therefore, as shown in FIG. 2 as an example, the wearer's sound field forming means 3 includes sound field selecting means 31, binaural sound field forming means 32, monaural sound field forming means 33, and an information layout default. It is composed of setting information 34 and wearer-specific customization information 35 .

For each wearer wearing the hearing device 10, the sound field selection means 31 selects the information layout default setting information 34, the wearer's Based on the customizing information 35 and the wearing information 21 of the hearing device 10 held in the wearing information holding means 2, a forming means for forming a sound field for the wearer is selected. Then, the selected forming means, that is, either the binaural sound field forming means 32 or the monaural sound field forming means 33 is activated.

Here, as described above, the wearing information 21 identifies for each wearer whether the hearing device 10 is worn on both ears or whether the hearing device 10 is worn on either the left ear or the right ear. have information to The information layout default setting information 34 is information that sets a default value regarding the layout position of the information sound source 20, and sets a predetermined default position. In addition, the customized information 35 for each wearer is a position where the arrangement of the information sound source 20 is customized for each wearer from the default value based on instructions from the commander of the group, the team organizer of the wearer group, or the wearer himself/herself. This is information indicating that it has been placed in the In other words, the information layout default setting information 34 and the wearer-specific customization information 35 determine what position the sound field of the audio information of each information sound source 20 is localized from the wearer's point of view.

Then, when it is found that the wearer wears the hearing device 10 on both ears as a result of referring to the wearing information 21, the binaural sound field forming means 32 generates information arrangement default setting information 34, wearing By referring to the customized information 35 for each person, the audio information of each information sound source 20 is changed so that the sound field of each audio information is localized at different positions as seen from the wearer, depending on the difference in the volume level given to both ears. After processing, they are output to the data distributing means 4 as right ear data 22a and left ear data 22b.

On the other hand, when it is found that the wearer wears the hearing device 10 on either the left ear or the right ear as a result of referring to the wearing information 21, the one-ear sound field forming means 33 The audio information from each information sound source 20 is processed so that the frequency and the volume level are mainly used for discriminating the audio information from the information sound source 20, and is output to the data distribution means 4 as data for one ear 23. .

As a result, in the wearer's sound field forming means 3, as described above, the information sound source 20 is processed as processed data that allows the sound field of the sound information to be easily distinguished from other sound information. is output to the corresponding hearing device 10 via the data distribution means 4. Therefore, the wearer of the hearing device 10 can easily understand the audio information of the corresponding information sound source 20 by listening to the processed data received via the data distribution means 4 .

The data distribution means 4 accesses the wearing information holding means 2, acquires information about the hearing device 10 worn by the wearer of the distribution destination, and sends the information to the hearing device 10 worn by the wearer. Then, the processed data created by the wearer's sound field forming means 3 is sent as voice information from the corresponding information sound source 20 . As a result, various audio information from each information sound source 20 is presented in a format that can be appropriately recognized by the wearer designated as a distribution destination.

It should be noted that the voice information of the information sound source 20 has absolute position information as an attribute for guidance, and the position and posture of the wearer can be estimated with the assistance of the hearing device 10 or some other means. In this case, the information sound source 20 is fixed at the position indicated by the absolute position information. On the other hand, in the case of the information sound source 20 (information sound source) not accompanied by absolute position information for guidance, the sound field position of the information sound source 20 can be freely set by the wearer or the commander. , can be placed in any position.

As for the arrangement position of the information sound source 20, the default position is normally set in advance as the information arrangement default setting information 34. It is possible to arbitrarily customize and specify the position.

(Description of effects of the embodiment)
As described in detail above, the present embodiment provides the following effects.

Firstly, while flexibly responding to the lending and borrowing of the hearing device 10 among wearers acting in a group and changes in the wearing state, the voice information is reliably provided to each wearer to whom the voice information is to be provided. can deliver. The reason for this is that the audio information is transmitted to the hearing device 10 worn by the wearer by designating the wearer, not by designating the hearing device 10. That is, This is because the wearing information holding means 2 controls the distributing operation of the audio information using the wearing information associated (mapped) between the wearer and the hearing device 10 as a key.

Second, each wearer is able to distinguish between different audio information even when multiple audio information is delivered. The reason for this is that the wearer's sound field forming means 3 that forms the sound field of the audio information in conjunction with the attributes of the information sound source 20 that is the source of the audio information and the wearing state of the hearing device 10 is provided. In addition to the above attributes, it is possible to form a sound field suitable for each of the wearing conditions of the hearing device 10, such as whether the hearing device 10 is worn on both ears or on either one of the left and right ears. Because we can. Furthermore, with respect to the position of the information sound source that is the source of the voice information, the system commander or the like can preset an appropriate arrangement state as a default value in the information arrangement default setting information 34, or The customized information 35 for each wearer can be optionally customized and set for each wearer as needed.

Thirdly, even if the wearers of each hearing device 10 are organized as a group, each wearing vehicle commonly or arbitrarily organized for each individual constituting the group or for all the members of the group It is possible to easily provide voice information classified according to each group member in common to all members of the group unit. The reason for this is that the wearer information selection means 5, the voice information distribution control means 6, and the wearer group management means 8 are provided as management means relating to distribution destinations of voice information and group organization.

Fourthly, by selecting either the sound field localization fixed on the absolute coordinates or the sound field localization relative to the wearer, voice information for guidance or the like and voice information for the individual to use for information identification. and can be used together in a separate state, and can be controlled not only by the commander of the group, but also by the wearer depending on the capabilities of the hearing device 10. The reason for this is that the use of voice information accompanied by absolute position information as the information sound source 20 and the use of voice information not accompanied by absolute position information are allowed to coexist, and the presence or absence of addition of absolute position information to the information sound source 20 is supported. This is because the wearer's sound field forming means 3 for forming a sound field that is similar to the wearer's sound field is provided.
