[Modes for carrying out the invention]

[0009] The principles of this disclosure will be described with reference to several exemplary embodiments. These embodiments are described for illustrative purposes only and should be understood as helping those skilled in the art to understand and implement this disclosure without implying any limitation on the scope of this disclosure. The disclosures described herein may be implemented in various ways other than those described below.

[0010] In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meanings as those generally understood by those skilled in the art to which this disclosure belongs.

[0011] Embodiments of the present disclosure will be described below with reference to the drawings. Each drawing is merely illustrative for illustrating one or more embodiments. Each drawing may be associated not only with one specific embodiment but also with one or more other embodiments. As those skilled in the art will understand, various features or steps described with reference to any one drawing can be combined with features or steps shown in one or more other drawings, for example, to create embodiments not explicitly shown or described. Not all features or steps shown in any one drawing to illustrate an exemplary embodiment are necessarily required, and some features or steps may be omitted. The order of steps described in any of the drawings may be changed as appropriate.

[0012] <System Configuration> Referring to Figure 1, the configuration of the distribution system 1 according to the embodiment will be described. Figure 1 is a diagram showing an example of the configuration of the distribution system 1 according to the embodiment. In the example of Figure 1, the distribution system 1 includes an information processing device 10 and a distribution server 20. The distribution system 1 also includes a detachable sound output device (predetermined device) 30A, a detachable sound output device 30B, and a detachable sound output device 30C. Hereafter, when it is not necessary to distinguish between the detachable sound output devices 30A to 30C, they will be simply referred to as "detachable sound output device 30" as appropriate.

[0013] The number of information processing devices 10, distribution servers 20, and detachable audio output devices 30 is not limited to the example in Figure 1. The information processing device 10 may be built into or externally mounted to each detachable audio output device 30. Furthermore, the information processing device 10 may be the same device as the distribution server 20.

[0014] In the example of FIG. 1, the information processing device 10, the distribution server 20, and the detachable acoustic output device 30 are connected so as to be able to communicate via the network N. Examples of the network N include, for example, BLE (Bluetooth (registered trademark) Low Energy), wireless LAN (Local Area Network), LAN, bus, Internet, and mobile communication systems. Examples of the mobile communication system include, for example, the fifth generation mobile communication system (5G), the fourth generation mobile communication system (4G), the third generation mobile communication system (3G), and the like.

[0015] The information processing device 10 controls the detachable acoustic output device 30 based on music or the like transmitted (for example, broadcast, multicast, or unicast) from the distribution server 20.

[0016] The distribution server 20 realizes a silent disco or the like by sequentially transmitting a plurality of music pieces via a network N such as wireless. The distribution server 20 may broadcast music using, for example, the Auracast (registered trademark) function of the Bluetooth standard. Here, the silent disco referred to herein is, for example, an event in which each participant wears wireless headphones capable of receiving the broadcast music and shares the same music.

[0017] The detachable acoustic output device 30 receives the music data transmitted from the distribution server 20, converts it from an electrical signal to sound, and outputs it from the speaker. The detachable acoustic output device 30 may have, for example, wireless headphones or wireless earphones. Further, the detachable acoustic output device 30 transmits information based on measurement data of various sensors built in or externally attached to the detachable acoustic output device 30 to the information processing device 10. Further, the detachable acoustic output device 30 sets the volume of the speaker or the like according to an instruction received from the information processing device 10.

[0018] <Configuration of the detachable acoustic output device 30> Referring to FIG. 2, the configuration of the detachable acoustic output device 30 according to the embodiment will be described. FIG. 2 is a diagram showing an example of the configuration of the detachable acoustic output device 30 according to the embodiment. In the example of FIG. 2, the detachable acoustic output device 30 includes a wireless headset 31, a detachable sensor (wearing sensor) 32, an operation sensor 33, and an information processing device 34.

[0019] The wireless headset 31 receives the music data transmitted from the distribution server 20, converts an electrical signal into sound, and outputs it from the speaker. The wireless headset 31 may receive the transmitted music data using the Auracast function of the Bluetooth standard.

[0020] The attachment / detachment sensor 32 is a sensor for detecting whether or not the wireless headphones 31 are attached to the user's head, for example, based on infrared light or pressure. The attachment / detachment sensor 32 may be built into the wireless headphones 31 or attached externally. For example, the attachment / detachment sensor 32 may be an infrared sensor for detecting the position of the wireless headphones 31 attached to the user's head. In this case, the attachment / detachment sensor 32 measures the distance and position from the user's head by emitting infrared light and receiving the reflected light. This allows for the detection of whether or not the headphones are being worn, and enables automatic control of music playback and pausing according to the wearing status of the wireless headphones 31 on the user. Alternatively, the attachment / detachment sensor 32 may be a pressure sensor for detecting whether or not the wireless headphones 31 are being worn to the user's head. In this case, the attachment / detachment sensor 32 is built into the headband or earcup and measures the pressure applied to the user's head. This allows for the determination of whether or not the headphones are being worn, and if they are not being worn, actions such as stopping music playback can be taken. The attachment / detachment sensor 32 is not limited to these examples and may utilize other technologies. For example, other sensor technologies such as proximity sensors and capacitive sensors can be used to detect how the headphones are worn on the user's head. Furthermore, combining multiple sensors allows for more accurate detection of the wearing status. For instance, combining an infrared sensor with a pressure sensor can measure both the position and pressure of the headphones on the user's head, resulting in more reliable wearing detection.

[0021] The motion sensor 33 is a sensor for detecting specific actions of a user wearing the wireless headphones 31. The motion sensor 33 may be, for example, at least one of an accelerometer and a camera. The motion sensor 33 may be built into the wireless headphones 31 or it may be external.

[0022] The information processing device 34 is a computer (e.g., a microcomputer) that controls each part of the detachable acoustic output device 30. The information processing device 34 may communicate with the information processing device 10, for example, by wireless communication. The information processing device 34 may be built into the wireless headphones 31 or it may be external. The hardware configuration of the information processing device 34 may be the same as the hardware configuration of the information processing device 10, which will be described later.

[0023] <Configuration of the information processing device 10> Referring to Figure 3, the configuration of the information processing device 10 according to the embodiment will be described. Figure 3 is a diagram showing an example of the configuration of the information processing device 10 according to the embodiment. In the example of Figure 3, the information processing device 10 has an acquisition unit 11 and a control unit 12. Each of these units may be realized through the cooperation of one or more programs installed in the information processing device 10 and hardware such as the processor 101 and memory 102 of the information processing device 10.

[0024] The acquisition unit 11 acquires information indicating the status of the detachable sound output device 30, which receives transmitted music data and converts it into sound, being worn by the user, information indicating that the user is operating in a specific manner, and information regarding the transmitted music. Here, a specific manner may include, for example, a state in which the user is moving their body in time with the rhythm of the transmitted music, such as headbanging, swaying their body, clapping their hands, or stomping their feet.

[0025] The control unit 12 controls the volume of the detachable sound output device 30 based on the state in which the detachable sound output device 30 is attached to the user and the degree of association between the first song that was transmitted when the user was operating in a specific manner and the second song that is currently being transmitted.

[0026] The control unit 12 may increase the volume of the detachable sound output device if, for example, the detachable sound output device 30 is not attached by the user and the degree of association between the first song that was transmitted when the user was operating in a specific manner and the second song that is currently being transmitted is above a threshold.

[0027] Furthermore, the control unit 12 may, for example, reduce the volume of the detachable sound output device 30 if the detachable sound output device 30 is attached by the user and the degree of association between the first song that was transmitted when the user was operating in a specific manner and the second song that is currently being transmitted is not equal to or greater than a threshold.

[0028] <Hardware configuration of the information processing device 10> Figure 4 shows an example of the hardware configuration of an information processing device 10 according to an embodiment. In the example in Figure 4, the information processing device 10 (computer 100) includes a processor 101, memory 102, and a communication interface 103. These parts may be connected by a bus or the like. The memory 102 stores at least a portion of the program 104. The communication interface 103 includes an interface necessary for communication with other network elements.

[0029] When program 104 is executed in cooperation with the processor 101 and memory 102, etc., the computer 100 performs at least some of the processing of embodiments of this disclosure. Memory 102 may be any type suitable for a local technology network. Memory 102 may, in non-limiting examples, be a non-temporary computer-readable storage medium. Memory 102 may also be implemented using any suitable data storage technology, such as semiconductor-based memory devices, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory. Although only one memory 102 is shown for computer 100, computer 100 may have several physically different memory modules. Processor 101 may be any type. Processor 101 may include one or more general-purpose computers, dedicated computers, microprocessors, digital signal processors (DSPs), and, in non-limiting examples, processors based on multicore processor architectures. Computer 100 may have multiple processors, such as application-specific integrated circuit chips that are time-dependent to a clock that synchronizes the main processor.

[0030] Embodiments of the present disclosure may be implemented in hardware or in dedicated circuitry, software, logic, or any combination thereof. Some embodiments may be implemented in hardware, while others may be implemented in firmware or software that can be executed by a controller, microprocessor, or other computing device.

[0031] This disclosure also provides at least one computer program product tangibly stored on a non-temporary computer-readable storage medium. The computer program product includes computer-executable instructions, such as instructions contained in a program module, and is executed on a device on a target real or virtual processor to perform the processes or methods of this disclosure. The program module includes routines, programs, libraries, objects, classes, components, data structures, etc., that perform a specific task or implement a specific abstract data type. The functionality of the program module may be combined or divided among the program module as desired in various embodiments. The machine-executable instructions of the program module can be executed on a local or distributed device. On a distributed device, the program module can reside on both local and remote storage media.

[0032] Program code for performing the methods of this disclosure may be written in any combination of one or more programming languages. These program codes are provided to a processor or controller of a general-purpose computer, a dedicated computer, or other programmable data processing device. When the program code is executed by the processor or controller, the functions / operations in the flowchart and / or block diagrams it implements are performed. The program code may run entirely on a machine, partially on a machine, partially as a standalone software package, partially on a machine, partially on a remote machine, or entirely on a remote machine or server.

[0033] Programs can be stored and supplied to a computer using various types of non-temporary computer-readable media. Non-temporary computer-readable media include various types of tangible recording media. Examples of non-temporary computer-readable media include magnetic recording media, magneto-optical recording media, optical disc media, and semiconductor memory. Magnetic recording media include, for example, flexible disks, magnetic tapes, and hard disk drives. Magneto-optical recording media include, for example, magneto-optical disks. Optical disc media include, for example, Blu-ray discs, CD (Compact Disc)-ROM (Read Only Memory), CD-R (Recordable), and CD-RW (ReWritable). Semiconductor memory includes, for example, solid-state drives, mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (random access memory). Programs may also be supplied to a computer using various types of temporary computer-readable media. Examples of temporary computer-readable media include electrical signals, optical signals, and electromagnetic waves. Temporary computer-readable media can supply programs to a computer via wired communication channels such as electric wires and optical fibers, or via wireless communication channels.

[0034] <Processing> Next, with reference to Figure 5, an example of processing by the information processing device 10 according to the embodiment will be described. Figure 5 is a flowchart of an example of processing by the information processing device 10 according to the embodiment. The processing in Figure 5 may be executed at intervals such as periodic intervals. Alternatively, the processing in Figure 5 may be executed, for example, when the distribution server 20 starts transmitting the next song. In the following, an example of transmission (broadcast or multicast) will be described as an example of transmission, but the transmission in this disclosure may also be individual transmission (unicast).

[0035] In step S101, the acquisition unit 11 acquires information indicating the state in which the detachable sound output device 30 is attached to the user, information indicating that the user is operating in a specific manner (e.g., dancing, headbanging), and information regarding the transmitted music. The information indicating the state in which the detachable sound output device 30 is attached to the user may also be information detected by the attachment / detachment sensor 32.

[0036] Information indicating that a user is operating in a particular manner may include at least one of the information measured by the 30 acceleration sensor of the detachable acoustic output device and a video image of the user. In this case, the control unit 12 may determine that a user is operating in a particular manner if, for example, the acceleration measured by the motion sensor 33, which is an acceleration sensor, indicates that it is vibrating at a specific period. In this case, the control unit 12 may, for example, collect acceleration data associated with the user's movements in real time. The control unit 12 may then analyze the collected acceleration data using signal processing techniques to detect a vibration pattern at a specific period. In this case, the control unit 12 may, for example, extract periodic vibration components using Fourier transforms.

[0037] Furthermore, the control unit 12 may, for example, use AI (Artificial Intelligence) to estimate (infer) the period of the user's vibrations based on the video footage captured by the motion sensor 33, which is a camera. The control unit 12 may then determine that the user is operating in a specific manner if the user is vibrating at a specific frequency.

[0038] Furthermore, the control unit 12 may, for example, use AI to determine whether the user is operating in a specific manner based on video footage from a camera installed in the facility. In this case, the control unit 12 may analyze the user's movement patterns by inputting the video footage of the user as the subject into a motion recognition model using deep learning. More specifically, the control unit 12 may analyze the video footage using a convolutional neural network (CNN) or a recurrent neural network (RNN) to estimate the period of the user's vibrations. Then, if vibrations at a specific period are detected, the control unit 12 may determine that the user is operating in a specific manner.

[0039] The term "period" in this disclosure refers to information indicating the rhythm or tempo of a user's physical movements in a specific manner. Tempo indicates the speed of music or movement and is usually expressed as the number of beats per minute (BPM: Beats Per Minute). A faster tempo results in a shorter period, while a slower tempo results in a longer period. Therefore, the period of a user's physical movements indicates the time interval at which those movements are repeated in accordance with the rhythm or tempo.

[0040] Next, the control unit 12 controls the volume of the detachable sound output device 30 based on the state in which the detachable sound output device 30 is attached to the user and the degree of association between the first song that was transmitted when the user was acting in a specific manner and the second song that is currently being transmitted (step S102). Here, the control unit 12 may determine the degree of association based on the period of the user's actions when the first song was being transmitted and the user was acting in a specific manner. In this case, the control unit 12 may, for example, use AI or the like to determine the period during which the user was moving their body, such as dancing, when the first song was being transmitted, based on measurement data from the motion sensor 33. This period may be, for example, the period during which the user is moving their body in time with the rhythm of the transmitted song, such as headbanging, clapping, stomping their feet, and dancing. The control unit 12 may then determine a higher degree of association between the first song and the second song if the period during which the user was moving their body, such as dancing, when the first song was being transmitted is close to the rhythm or tempo of the second song. Furthermore, the control unit 12 may determine the degree of association between the first and second songs based on song information such as genre or artist of the first and second songs. In this case, for example, if the user was performing a specific type of action, such as headbanging, when the first song was being transmitted, and both the first and second songs are rock, the control unit 12 may determine a high degree of association.

[0041] <<Processing when the detachable sound output device 30 is attached to the user>> Next, with reference to Figure 6, an example of processing of the information processing device 10 according to the embodiment when the detachable sound output device 30 is attached to the user will be described in more detail. Figure 6 is a flowchart of an example of processing of the information processing device 10 according to the embodiment when the detachable sound output device 30 is attached to the user. The processing in Figure 6 may be executed at intervals such as periodic times. In Figure 6, an example is described in which, when the user is operating in a specific manner, such as dancing to the first song, information about the first song is recorded as information about a song that suits the user's taste. Note that this disclosure is not limited to the example in Figure 6.

[0042] In step S201, the control unit 12 detects that the detachable sound output device 30 is attached to the user. Next, the control unit 12 detects that the user is operating in a specific manner (step S202). Next, the control unit 12 determines whether the degree of agreement between the period in which the user is operating in the specific manner and the tempo of the first song that was transmitted when the user was operating in the specific manner is above a threshold (step S203). Here, the control unit 12 may determine, for example, that the smaller the difference between the period in which the user is operating in the specific manner and the tempo of the first song that was transmitted when the user was operating in the specific manner, the higher the value of the degree of agreement.

[0043] If the degree of match is not equal to or greater than the threshold (NO in step S203), the process is terminated. On the other hand, if the degree of match is equal to or greater than the threshold (YES in step S203), the control unit 12 records the information of the first song (step S204) and terminates the process.

[0044] <<Processing when the detachable sound output device 30 is not attached to the user>> (An example of informing users who are taking a break that recommended music is available for streaming.) Next, with reference to Figure 7, an example of processing by the information processing device 10 according to the embodiment when the detachable sound output device 30 is not attached to the user will be described in more detail. Figure 7 is a flowchart of an example of processing by the information processing device 10 according to the embodiment when the detachable sound output device 30 is not attached to the user. The processing in Figure 7 may be executed at intervals such as periodic intervals. Alternatively, the processing in Figure 7 may be executed, for example, when the distribution server 20 starts transmitting the next song. Figure 7 illustrates an example in which the information processing device 10 notifies a user who has removed their headphones (for example, while taking a break) that recommended songs are being distributed, for example in a silent disco. Note that this disclosure is not limited to the example in Figure 7.

[0045] In step S301, the control unit 12 detects that the detachable sound output device 30 is not being worn by the user. Next, the control unit 12 determines whether the degree of relevance between the first song that was being transmitted when the user was operating in a specific manner and the second song currently being transmitted is above a threshold (step S302). If the degree of relevance between the first song and the second song is not above the threshold (NO in step S302), the process ends. On the other hand, if the degree of relevance between the first song and the second song is above the threshold (YES in step S302), the control unit 12 increases the volume of the detachable sound output device 30 (step S303) and ends the process. This allows, for example, a user who has removed their headphones to realize that a song similar to the one they were previously dancing to is being transmitted, and to encourage the user to put on their headphones and dance.

[0046] In this case, the control unit 12 may, for example, increase the volume of a specific frequency of the detachable sound output device 30. In this case, the control unit 12 may, for example, increase the volume only of the low-frequency range, which is relatively easy to hear even when the user has removed headphones or the like.

[0047] Furthermore, the control unit 12 may increase the volume of a specific user's detachable sound output device 30 based on the behavior of other users in a specific manner. In this case, the control unit 12 may record the number of other users who were operating in a specific manner when the first song was being transmitted during step S204 in Figure 6. Then, in step S302 in Figure 7, the control unit 12 may determine whether the degree of association between the first song and the second song is above a threshold, and whether the number of other users who were operating in a specific manner when the first song was being transmitted is above a first threshold. If the degree of association between the first song and the second song is above a threshold, and the number of such other users is above the first threshold, the control unit 12 may determine whether the number of other users who are increasing the volume of the detachable sound output device 30 is above a second threshold. If the number of such other users is above the second threshold, the control unit 12 may increase the volume of the specific user's detachable sound output device 30. This allows, for example, to encourage each user who enjoys dancing in a group and is currently taking a break to dance in a group.

[0048] Furthermore, the control unit 12 may return the volume of the detachable sound output device 30 to its original level if the user attempts to put on the detachable sound output device 30. In this case, the control unit 12 may detect that the detachable sound output device 30 is being worn by the user based on measurement data from, for example, the motion sensor 33, the attachment / detachment sensor 32, and a sensor that detects when the arm of the detachable sound output device 30 is extended. In this case, the control unit 12 may, for example, analyze the acceleration measured by the motion sensor 33 using AI or the like to detect that the detachable sound output device 30 is being worn by the user. The control unit 12 may also detect that the wireless headphones 31 are being worn on the user's head based on, for example, infrared rays or pressure detected by the attachment / detachment sensor 32. The case where a sensor that detects when the arm of the detachable sound output device 30 is extended is described in more detail. The arm is the part that supports the ear cup of the detachable sound output device 30 and may be adjustable to fit the user's head. A sensor that detects when the arm is extended may monitor the extension and retraction of the arm in real time and detect when the arm has been extended to a predetermined position. Based on this detection result, the control unit 12 may determine that the detachable sound output device 30 is being attached to the user. In other words, when the user tries to place the housing of the detachable sound output device 30 to their ear, the arm extends, which is detected by the sensor, and this allows the volume, which was increased before the user attached the detachable sound output device 30, to be returned to its original volume.

[0049] <<Processing when the detachable sound output device 30 is attached to the user>> (An example of informing a user who is dancing that a song that is not recommended is being streamed.) The information processing device 10 may, for example, inform a user wearing headphones (for example, while dancing) that unsuitable music is being streamed in a silent disco or the like. In this case, the control unit 12 may determine whether or not the detachable sound output device 30 is being worn by the user. If the detachable sound output device 30 is being worn by the user, the control unit 12 may determine whether or not the degree of relevance between the first song that was being transmitted when the user was operating in a particular manner and the second song currently being transmitted is above a threshold. If the degree of relevance between the first song and the second song is not above a threshold, the control unit 12 may reduce the volume of the detachable sound output device 30. This allows, for example, a user who has removed their headphones to realize that music unrelated to the music they were previously dancing to is being streamed, and encourages the user to remove their headphones and take a break.

[0050] In this case, the control unit 12 may, for example, reduce the volume of a specific frequency of the detachable sound output device 30. In this case, the control unit 12 may, for example, reduce the volume only of the high-frequency portion that is relatively likely to be irritating to the user.

[0051] Furthermore, the control unit 12 may reduce the volume of a specific user's detachable sound output device 30 based on the behavior of other users in a specific manner. In this case, the control unit 12 may determine whether the number of other users who were operating in a specific manner when the first song was being transmitted is equal to or greater than a first threshold. If the number of such other users is equal to or greater than the first threshold, the control unit 12 may determine whether the number of other users whose volume of the detachable sound output device 30 is reduced is equal to or greater than a second threshold. If the number of such other users is equal to or greater than the second threshold, the control unit 12 may reduce the volume of the specific user's detachable sound output device 30. This allows, for example, a group of users who enjoy dancing together and are currently dancing to be prompted to take a break all at once.

[0052] Furthermore, the control unit 12 may restore the volume of the detachable sound output device 30 to its original level if the user of the detachable sound output device 30 operates in a specific manner. This allows the volume to be restored to its original level, for example, if the user dances or performs other actions despite being prompted to take a break.

[0053] <Variation> The information processing device 10 may be a device contained in a single enclosure, but the information processing device 10 of this disclosure is not limited to this. Each part of the information processing device 10 may be implemented by cloud computing, for example, consisting of one or more computers. Alternatively, the information processing device 34 of each detachable sound output device 30 may be used instead of the information processing device 10. Furthermore, the information processing device 10 may be the same device as the distribution server 20. Such information processing devices are also included as examples of "information processing devices" in this disclosure.

[0054] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of symbols]
