DETAILED DESCRIPTION

[0044] Hereinafter, embodiments of the recording device and the like will be described with reference to the drawings. In the embodiments, components denoted by the same reference numerals perform the same operations, and therefore, duplicate descriptions may be omitted.

[0045] Furthermore, the terms used below are generally defined as follows. Furthermore, the semantics of these terms should not always be interpreted as the meanings shown here, but should be interpreted with reference to the description thereof when they are described separately below, for example.

[0046] Abdominal sounds refer to sounds emitted from the user's abdomen. Abdominal sounds may include, for example, intestinal sounds emitted from the intestines. In addition, abdominal sounds may also include sounds generated by blood flow in the abdomen (for example, abdominal aortic sounds) or sounds emitted from organs such as the stomach.

[0047] The sound information refers to information obtained from the abdominal sound. The sound information may be the recorded abdominal sound data itself, or data obtained by processing or editing the data.

[0048] Life information is information related to a user's living conditions. Life conditions may include various elements related to the user's actions, status, etc. For example, life information may include excretion relationship information related to the user's excretion status, dietary information related to the user's dietary status, and status activities related to living habits other than dietary status (referring to behaviors or actions that the user repeatedly performs in daily life). However, life information is not limited to this, but may also include information related to other elements, and may also include information related to only part of these elements. Furthermore, information related to each element of life information (excretion relationship information, dietary information, activity status information, etc.) may respectively include information related to more detailed elements.

[0049] Basic information is information related to the user's behavior or characteristics. For example, the basic information may include various information such as the user's height, weight, age, gender, body fat percentage, muscle mass, pulse rate, respiratory rate, blood pressure, etc. In addition, the basic information may also include the user's answers to questionnaires, information generated based on the answers, and information about the user's past resume. For example, the answers to questionnaire items used for the diagnosis of people with intestinal disorders can objectively represent the user's physique. Basic information is, for example, information that is input in advance by the user, but is not limited to this. For example, it can also be information obtained through a wearable terminal carried by the user, or information obtained from an external database that records user information.

[0050] An identifier for a certain item is a word or symbol that specifically represents the item. Although the identifier is, for example, an ID, its type is not limited as long as it is information that can identify the corresponding item. That is, the identifier can be the name of the item it represents, or it can be a combination of symbols in a specifically corresponding manner.

[0051] Acquisition may include acquisition of items input by a user, etc., and may also include acquisition of information stored in its own device or other devices (which may be information that has been stored in advance or information generated by information processing in the device). Acquisition of information stored in other devices may include acquisition of information stored in other devices via an API, etc., and may also include acquisition of the contents of documents (including the contents of web pages, etc.) provided by other devices. In addition, acquisition of information by optical character reading for images may also include acquisition of information in a different format from the original information.

[0052] In addition, the acquisition of information can also utilize the so-called machine learning method. The utilization of the machine learning method can be done as follows, for example. That is, a learning machine (learning information) is constructed using the machine learning method, which takes a specific type of input information as input and outputs the type of output information you want to obtain. For example, more than two groups of input information and output information are prepared in advance, and the two or more groups of information are provided to a module for constituting a learning machine for machine learning to construct a learning machine, and the constructed learning machine is accumulated in a storage unit. In addition, the learning machine can also be referred to as a classifier. In addition, as a method of machine learning, there are, for example, deep learning, random forest, SVM, etc., and the types are not limited. In addition, in machine learning, for example, functions in various machine learning frameworks such as fastText, tinySVM, random forest, TensorFlow, and various existing program libraries can be used.

[0053] In addition, the learning machine is not limited to being obtained through machine learning. The learning machine can also be, for example, a table that represents the correspondence between an input vector based on input information and output information. At this time, the output information corresponding to the feature vector based on the input information can be obtained from the table, or two or more input vectors in the table and parameters for weighting each input vector can be used to generate a vector that is similar to the feature vector based on the input information, and the final output information can be obtained using the output information and parameters corresponding to each input vector used in the generation. In addition, the learning machine can also be, for example, a function that represents the relationship between an input vector based on input information and information used to generate output information. At this time, for example, the information corresponding to the feature vector based on the input information can be obtained through a function, and the output information can be obtained using the obtained information.

[0054] The output of information is a concept that includes display on a display, projection using a projector, typing using a printer, audio output, transmission to an external device, accumulation on a storage medium, transmission of processing results to other processing devices or other programs, etc. Specifically, it includes, for example, display of information on a web page, transmission as an e-mail, etc., or output of information for printing.

[0055] The acceptance of information is a concept that includes the acceptance of information input from input devices such as a keyboard, mouse, or touch screen, the reception of information sent from other devices via wired or wireless communication lines, or the acceptance of information read from storage media such as optical disks, magnetic disks, and semiconductor memories.

[0056] Implementation

[0057] In this embodiment, a portable information terminal is used as a recording device. The recording device is configured to detect an unsuitable environment or a suitable environment when recording abdominal sounds, and perform processing according to the detection result. Hereinafter, an information processing system 1 configured using such a recording device will be described.

[0058] Figure 1 It is a diagram showing an overview of an information processing system 1 according to one embodiment of the present invention.

[0059] In this embodiment, the information processing system 1 includes an information processing device 100 and a portable information terminal (an example of a recording device) 6. The information processing device 100 and the portable information terminal 6 can communicate with each other via a network such as a local area network or the Internet. In addition, the configuration of the information processing system 1 is not limited to this. The number of each device included in the information processing system 1 is not limited, and the information processing system 1 may also include other devices.

[0060] The user of the information processing system 1 can use the portable information terminal 6 to use the information processing system 1. The portable information terminal 6 can also be referred to as a terminal device. In the present embodiment, for example, a terminal such as a so-called smart phone and each having a built-in microphone 81 is represented as a portable information terminal 6. Furthermore, the terminal used as the portable information terminal 6 is not limited to such a smart phone. For example, a personal computer (PC) such as a notebook computer, that is, a portable information terminal 600b, can be used, and other devices such as a tablet-type information terminal device can also be used. In addition, as a microphone, an external microphone 681b can also be used. In the following example, although the case where a smart phone is used as the portable information terminal 6 is assumed for explanation, it is not limited to this.

[0061] Figure 2 is a block diagram of the information processing device 100 . Figure 3 2 is a block diagram of the portable information terminal 6.

[0062] like Figure 2 As shown, the information processing device 100 includes a depositing unit 110, a receiving unit 120, a receiving unit 130, a processing unit 140, and a sending unit 170. The information processing device 100 is, for example, a server device.

[0063] The storage unit 110 includes a learning information storage unit 111 and a user information storage unit 115 .

[0064] The learning information storage unit 111 stores previously acquired learning information. In the present embodiment, the input information is used as learning input information including sound information, and the output information is used as the value of a predetermined output indicator related to the activity state of the intestine, thereby producing learning information. For example, the learning information is generated using the so-called machine learning method as described above. Although the learning information is generated by the information processing device 100, for example, it is not limited to this. That is, the learning information storage unit 111 may also store learning information generated in a device other than the information processing device 100.

[0065] The user information is stored in the user information storage unit 115. In the present embodiment, the user information is information that matches the identifier for identifying the user who uses the information processing system 1, that is, the user identifier, with information about the user. The user information may include various information. For example, it may include information sent from the portable information terminal 6 used by the user, and information obtained from the user through the information processing device 100 as described later. For example, in addition to the basic information of the user, voice information or life information may correspond to the information sent from the portable information terminal 6 used by the user.

[0066] The receiving unit 120 receives information sent from other devices. The receiving unit 120 stores the received information in, for example, the storage unit 110. In this embodiment, the user uses, for example, the portable information terminal 6 to input information, etc., and sends it to the information processing device 100. The receiving unit 120 can store each sent information in the storage unit 110 in correspondence with the user identifier. In addition, as described later, in this embodiment, it is possible to receive sound information sent from each portable information terminal 6 and store it in the storage unit 110 in correspondence with the user identifier. And, when receiving this information from the portable information terminal 6, the receiving unit 120 can determine the user identifier of the user involved in the message based on the sent information.

[0067] The receiving unit 130 receives information inputted using an input means (not shown) connected to the information processing device 100. The receiving unit 130 stores the received information in, for example, the storage unit 110. The input means may be any one of a numeric keypad, a keyboard, a mouse, or a menu screen.

[0068] The processing unit 140 includes a sound information acquisition unit 141, a life information acquisition unit 145, a bowel score acquisition unit 149, and a bowel score output unit 161. The processing unit 140 performs various processes. The various processes are, for example, processes performed by each unit of the processing unit 140 as follows.

[0069] The voice information acquisition unit 141 acquires voice information of one user. In the present embodiment, the voice information acquisition unit 141 acquires voice information transmitted from the user's portable information terminal 6 and received by the receiving unit 120 .

[0070] The life information acquisition unit 145 acquires life information. For example, the life information acquisition unit 145 acquires information stored in the user information storage unit 115. In addition, the life information acquisition unit 145 may also acquire basic information of the user.

[0071] The intestinal score acquisition unit 149 uses input information including sound information acquired by the sound information acquisition unit 141 and learning information prepared in advance to acquire an intestinal score related to the state of the user's intestine. In the present embodiment, the intestinal score acquisition unit 149 acquires the value of a prescribed output indicator using the learning information stored in the learning information storage unit 111, and acquires the intestinal score using the value of the output indicator. As the prescribed output indicator, for example, at least one of the state of defecation and the number of intestinal peristaltic movements per unit time is used. The number of intestinal peristaltic movements can also be referred to as the frequency of intestinal sounds occurring above a prescribed level (hereinafter, sometimes simply referred to as the frequency of intestinal sounds).

[0072] Specifically, the intestinal score acquisition unit 149 acquires the intestinal score, for example, as follows. The intestinal score acquisition unit 149 uses the sound information and learning information acquired by the sound information acquisition unit 141 to acquire the intestinal state score regarding the defecation state (normal, diarrhea, constipation, etc.) and the intestinal movement score regarding the peristaltic movement of the intestine (frequency, etc.). In the present embodiment, the intestinal score acquisition unit 149 inputs the sound information acquired by the sound information acquisition unit 141 into the learning information by a machine learning method, thereby acquiring the value of the output index. Thereafter, the intestinal relationship score (intestinal state score and intestinal movement score) is acquired based on the value of the output index. The intestinal relationship score can be acquired as the intestinal score.

[0073] Here, in the present embodiment, the sound information input to the intestinal score acquisition unit 149 is a spectrum image represented in a predetermined form as a result of analyzing the sound data (which may also be processed data) obtained by recording abdominal sounds through Fourier transform or fast Fourier transform. Furthermore, the sound information may be the sound data (which may also be processed data) itself, or data converted in other forms. Using the sound information sent from an instrument that records abdominal sounds to the information processing device 100, the processing unit 140 may prepare such sound information input to the intestinal score acquisition unit 149. Furthermore, a spectrum image, i.e., sound information, may be prepared in advance in an instrument other than the information processing device 100, such as an instrument that records abdominal sounds, and the like, and the sound information may be sent to the information processing device 100.

[0074] Furthermore, the learning information generated by classifying the user information into several types that can classify the user can also be stored in the learning information storage unit 111 in correspondence with the identifier that identifies the type. In this case, the intestinal score acquisition unit 149 can also be configured to acquire the learning information of the type corresponding to the specific identifier determined based on the user information from the learning information storage unit 111, and acquire the intestinal relationship score using the learning information. In this way, a more accurate output result can be obtained.

[0075] The intestinal score acquisition unit 149 can also obtain the score of the element based on the value of various output indicators such as excretion, diet, activity status, etc. that are different from sound information, or various life information, and obtain the intestinal score by combining these. For example, the scores of each element can be obtained based on whether the value of the output indicator or the content of various life information meets the specified conditions. After that, the intestinal score acquisition unit 149 uses the obtained intestinal relationship score and the scores of other elements to obtain the intestinal score. For example, the intestinal relationship score or other scores are added or multiplied by a specified method, and the intestinal score can also be obtained by applying a specified calculation formula to calculate. In addition, the intestinal score can be obtained by using a learning machine that uses a machine learning method such as taking each score as input and outputting the intestinal score. Each score can also be used in the acquisition of the intestinal score on a standardized basis as needed.

[0076] The bowel score acquisition unit 149 accumulates the acquired bowel scores in the user information storage unit 115 in association with the user identifier.

[0077] The bowel score output unit 161 outputs the bowel score obtained by the bowel score obtaining unit 149. In the present embodiment, the bowel score output unit 161 outputs the bowel score and other information by, for example, sending the bowel score and other information to the portable information terminal 6, but the present invention is not limited thereto. For example, the bowel score may be displayed on a display provided by the information processing device 100 in the form of text or images, and outputted.

[0078] The transmission unit 170 transmits information to other devices constituting the information processing system 1 via the network. The transmission unit 170 transmits information to the portable information terminal 6, for example. In other words, the transmission unit 170 outputs information to the portable information terminal 6, for example.

[0079] Next, the structure of the portable information terminal 6 is described. The portable information terminal 6 is a smart phone. In the information processing system 1, the portable information terminal 6 is used as a recording device for recording the abdominal sounds of the user, and is also used as a terminal for outputting information related to the bowel score obtained by the information processing device 100 so that the user can confirm it.

[0080] like Figure 3 As shown, the portable information terminal 6 includes a terminal deposit unit 10 , a terminal receiving unit 20 , a terminal accepting unit 30 , a terminal processing unit 40 , a terminal output unit 60 , a terminal transmitting unit 70 , and a sensor unit 80 .

[0081] The terminal storage unit 10 includes a voice information storage unit 11 , a device identification information storage unit 13 , and a life information storage unit 15 .

[0082] The sound information storage unit 11 stores the sound information (also referred to as recorded information) recorded by the sensor unit 80 of the portable information terminal 6. The sound information is sent to the information processing device 100 by the terminal sending unit 70, but it can be deleted from the sound information storage unit 11 when the sending is completed, or it can be stored until a predetermined period of time has passed, or it can be stored permanently until the user deletes it.

[0083] The device identification information storage unit 13 has the device identification information stored therein. The device identification information is, for example, information such as an identifier that can identify the type (model) of the portable information terminal 6, but is not limited thereto. The device identification information may also be, for example, an identifier that can identify the type of a device (for example, a hardware module constituting the microphone 81) of the portable information terminal 6. Different information may not be written into the device identification information storage unit 13.

[0084] The life information is accumulated in the life information storage unit 15. Although the life information is sent to the information processing device 100 by the terminal sending unit 70, it can be deleted from the life information storage unit 15 when the sending is completed, can be stored until a predetermined period has passed, and can be stored permanently until the user deletes it.

[0085] The life information accumulated in the life information storage unit 15 may also include information input by the user or information based thereon. Such information may be, for example, information received by the terminal receiving unit 30 or information acquired by the terminal processing unit 40 by performing calculations based on the information received by the terminal receiving unit 30.

[0086] In addition, the life information accumulated in the life information storage unit 15 may also include measured values ​​or information based thereon. Such information may be, for example, information measured by the sensor unit 80, or information acquired by the terminal processing unit 40 by performing calculations based on the information measured by the sensor unit 80. In addition, information measured by a sensor device communicatively connected to the portable information terminal 6 and transmitted to the portable information terminal 6 may also be used.

[0087] The terminal receiving unit 20 receives information transmitted from the information processing device 100 or other devices via the network. The terminal receiving unit 20 accumulates the received information in the terminal storage unit 10, for example, and makes the terminal processing unit 40 and the like available.

[0088] The terminal acceptance unit 30 receives various input operations on the portable information terminal 6 by the user who uses the portable information terminal 6. For example, operations are performed using the touch screen 61 or other operation buttons, but are not limited to this. For example, the terminal acceptance unit 30 can also accept input operations based on sounds that have been input through the microphone 81. It can also be considered that the terminal acceptance unit 30 accepts the information received by the terminal receiving unit 20 as information that has been input to the portable information terminal 6. That is, it can also be interpreted that the input of information to the portable information terminal 6 means that the information is indirectly input to the portable information terminal 6 by the user through other devices. In addition, the user provides information to the portable information terminal 6 by executing a program that automatically generates information or giving various information to the program to perform functions, etc., and this can also be regarded as the input of information to the portable information terminal 6.

[0089] The terminal processing unit 40 performs various processes. The various processes are processes performed by the various parts of the processing unit 140 using the various parts of the portable information terminal 6 as appropriate, for example, as follows.

[0090] In the present embodiment, the terminal processing unit 40 includes an environment detection unit 41 and a recording processing unit 51 for performing control related to recording of the user's abdominal sounds.

[0091] The environment detection unit 41 performs detection related to the environment for recording abdominal sounds. In the present embodiment, the environment detection unit 41 detects that the environment in which the portable information terminal 6 is located is a suitable environment for recording abdominal sounds. In other words, the environment detection unit 41 detects that the environment in which the portable information terminal 6 is located is not a suitable environment. Furthermore, the environment detection unit 41 may be configured to detect that the environment in which the portable information terminal 6 is located is an unsuitable environment that is not suitable for recording. The detection result is used in the recording processing unit 51.

[0092] Furthermore, in the following description, being in a suitable environment means not being in an unsuitable environment, and not being in an unsuitable environment means being in a suitable environment, but the present invention is not limited thereto. That is, not being in a suitable environment may not necessarily mean being in an unsuitable environment, or not being in an unsuitable environment may not necessarily mean being in a suitable environment. There may also be a situation where the environment is not in an unsuitable environment and is not in a suitable environment. In this case, the environment detection unit 41 may also be configured to detect the two situations where the environment in which the portable information terminal 6 is located is a suitable environment and an unsuitable environment.

[0093] An environment suitable for recording abdominal sounds, for example, indicates an environment in which the noise other than the abdominal sounds in the recorded sound information is small. It can also be said to be an environment in which sound information with a relatively small SN can be recorded. For example, the sound (ambient sound) occurring around the portable information terminal 6 recorded by the microphone 81, the electromagnetic noise, the sound (also referred to as ambient sound) occurring due to the change in the contact state (friction, contact, and separation, etc.) between the portable information terminal 6 and other objects, etc., conform to the noise. That is, a suitable environment can indicate an environment in which the contact state between the portable information terminal 6 and other objects does not change, an environment in which electromagnetic noise is difficult to occur or difficult to be recorded, and an environment in which the sound occurring around the portable information terminal 6 is small or difficult to be recorded.

[0094] Furthermore, the environment detection unit 41 is configured to determine the noise in the sound information by the following prescribed method. That is, in the present embodiment, the environment detection unit 41 is configured to determine the noise in the sound information according to the regularity of the sound. For example, it is detected whether the sound to be noted is a sound with regularity, and it is determined whether the sound is noise based on the result. The detection of whether the sound has regularity can be performed, for example, by the detection result of the interval of the sound, or by the result of Fourier analysis of the sound information. Generally speaking, since there are many cases where the occurrence of intestinal sounds in abdominal sounds is irregular, by determining regular sounds as noise, it is possible to effectively distinguish intestinal sounds from noise in the sound information. Furthermore, the determination of noise in the sound information is not limited to this, but can be determined by various methods. For example, the sound in a prescribed frequency band can be regarded as noise, and the noise can be determined by using learning information that can extract noise in the sound information. The environment detection unit 41 can also be configured to use these methods in combination. Furthermore, the sound information can also be appropriately sent to other devices (for example, the information processing device 100, etc.), and the other devices perform specific processing related to the determination of noise. In this case, the terminal receiving unit 20 may receive processing results of other devices, and the environment detection unit 41 may identify noise based on the received processing results, or detect the environment based on the received noise identification results.

[0095] As described later, the environment detection unit 41 detects the environment of recording based on the information obtained by the sensor unit 80. The detection may be performed before recording, during recording, or immediately after recording starts.

[0096] The recording processing unit 51 performs processing related to recording of abdominal sounds based on the detection result of the environment detection unit 41. The processing related to recording is, for example, processing related to the execution of recording or processing related to the completion of recording during recording. The processing related to the execution of recording is, for example, the start of recording or the user's operation for starting recording being accepted or not accepted. In addition, the processing related to the completion of recording during recording is, for example, the interruption, end, and suspension (interruption, etc.) of recording, or the user's operation for interruption of recording being accepted or not accepted, or the extension or shortening of a prescribed recording period. In addition, the processing related to recording may also be processing of the recording result (sound information), for example, it may be the destruction of sound information, or the correspondence of information related to adoption or not to sound information, or the correspondence of quality evaluation information (for example, information related to the size of noise, etc.) to sound information, or the transmission of sound information to an external device such as the information processing device 100. In addition, the processing related to recording may also be information related to the size of the ambient sound during recording, whether the user's posture or the posture of the portable information terminal 6 is appropriate, or information indicating the degree of these to the user. It can also be said that the notification to the user is guidance information output to the user to call attention or guide the improvement method.

[0097] Although detailed description will be given later, as an example, the recording processing unit 51 can be configured to perform the following processing. That is, the recording processing unit 51 can also be configured to output the specified guidance information from the portable information terminal 6 when the environment detection unit 41 detects that it is in an unsuitable environment or is not in a suitable environment. For example, the guidance information can be displayed on the touch screen 61 or output from a speaker not shown in the figure through the terminal output unit 60. As guidance information, it can be a display that calls the attention of users in an environment that is not suitable for recording, or a display of a method for improving the guidance environment. As guidance information, it is more preferable to output information related to the reason why the environment is not suitable for recording. In this way, it is possible to prevent recording under conditions where it is likely that it is difficult to obtain a high-quality recording result of abdominal sounds. The user changes the environment with reference to the guidance information, thereby making it easy to obtain a high-quality recording result of abdominal sounds. It can also be said that these processes performed by the recording processing unit 51 are processes for obtaining sound information in a suitable environment.

[0098] In addition, the recording processing unit 51 can also be configured to complete the recording using the microphone 81 or perform a prescribed process for utilizing the sound information obtained by the recording using the microphone 81 when the environment detection unit 41 detects that the recording is in a suitable environment or is not in an unsuitable environment. For example, as a prescribed process, the recording in the recording can also be completed only for a prescribed time. In this way, a recording result of abdominal sounds that is considered to be of high quality can be obtained reliably. In addition, in order to utilize the sound information obtained by the recording, the sound information can also be sent to the information processing device 100. In this way, using the recording result of abdominal sounds that are considered to be of high quality, a highly reliable intestinal score can be obtained in the information processing device 100. In addition, when sending the sound information, the user's life information or basic information can also be sent together with the sound information.

[0099] The terminal output unit 60 includes, for example, a display device, that is, a touch screen 61. The terminal output unit 60 outputs information by displaying the information on the touch screen 61. In addition, the method of outputting information is not limited to this, and it can also be output from a speaker or the like. Under the control of the terminal processing unit 40, the terminal output unit 60 can output the sound information obtained by recording the abdominal sound of the user to the information processing device 100.

[0100] The touch screen 61 functions as a display for displaying information and also accepts user operations. The touch screen 61 can also be understood as a part of the terminal acceptance unit 30. In addition, instead of the touch screen 61, a display device having only an information display function can also be used.

[0101] The terminal transmission unit 70 transmits the information acquired by the terminal processing unit 40 and the like, for example, via the network.

[0102] The sensor unit 80 includes a microphone 81 and an acceleration sensor 91. The sensor unit 80 measures the recording or measurement items using the microphone 81, and outputs the obtained information such as the sound data or the measured value. The obtained information is accumulated in the terminal storage unit 10, for example. Here, although the measured value is, for example, a value indicating the change of acceleration obtained by the acceleration sensor or a value indicating the change of air pressure obtained by the air pressure sensor, it is not limited to this.

[0103] For example, the microphone 81 is used to input the voice of the user during a call. In the present embodiment, the microphone 81 is used to record the abdominal sound of the user. The type and specific structure of the microphone 81 are not limited.

[0104] The acceleration sensor 91 is provided to detect the acceleration of the portable information terminal 6. The terminal processing unit 40 can detect the acceleration of the portable information terminal 6 using the acceleration sensor 91. That is, the terminal processing unit 40 can detect the posture of the portable information terminal 6 when the portable information terminal 6 is substantially stationary.

[0105] Furthermore, the sensor unit 80 may also include, for example, a pulse sensor, an illumination sensor, a camera, a GPS, or other location information sensor that can determine a location. In addition, the sensor unit 80 may also be a timer that measures the passage of time. The portable information terminal 6 may also be configured to function as an activity meter for obtaining information related to the user's activity amount such as the amount of calories consumed and the number of steps taken, or information related to the user's living habits such as the time when the user wakes up, the time when the user goes to bed, and the commuting time. Furthermore, based on the measured values ​​obtained by the sensor unit 80, information related to the user's living environment such as the region where the user lives, the climate, and the noise environment may be obtained and accumulated in the terminal storage unit 10.

[0106] Figure 4 It is a perspective view showing the portable information terminal 6 .

[0107] In this embodiment, the portable information terminal 6 has a rectangular plate-shaped housing 6b. A touch screen 61 is arranged on one surface of the housing 6b.

[0108] The microphone 81 is housed inside the frame 6b. In the present embodiment, the microphone 81 is arranged near the end of the frame 6b. In the frame 6b, the part near the microphone 81 becomes the sound collecting part 6c. The sound collecting part 6c is, for example, an opening formed in the frame 6b so that the sound can be transmitted from the outside of the frame 6b to the microphone 81, but it is not limited to this. Moreover, on the basis of the microphone 81, a microphone built into other parts can also be provided. That is, the portable information terminal 6 can also have more than two microphones. It is configured to use at least one or more microphones including the microphone 81 to record abdominal sounds.

[0109] In this embodiment, the sound collecting part 6c is arranged at the end of the frame 6b. It can also be said that the sound collecting part 6c is arranged at the side edge of the frame 6b with the surface where the touch screen 61 is arranged as the upper surface. In addition, it can also be said that the sound collecting part 6c is arranged at the side periphery of the frame 6b.

[0110] More specifically, the sound collecting unit 6c is located at the lower part of the portable information terminal 6. It can also be said that the sound collecting unit 6c is arranged at the lower edge of the frame 6b. An output port 6d of a speaker for calls is provided at the upper part of the portable information terminal 6. When the portable information terminal 6 is brought close to the user's head for a call, the output port 6d is arranged at the upper part close to the user's ear, and the sound collecting unit 6c is arranged at the lower part close to the user's mouth. In addition, in the present embodiment, it can be said that the lower side is the direction located at the lower side in the display screen or content displayed on the touch screen 61 when a conventional portable information terminal 6 is used.

[0111] Furthermore, a phone case (also called a protective cover) for protecting the portable information terminal 6 from impacts such as when it is dropped can be mounted on the frame 6b of the portable information terminal 6. The phone case can also be mounted on the frame 6b for other purposes such as decoration.

[0112] In the present embodiment, abdominal sounds can be recorded using the portable information terminal 6 as follows, for example.

[0113] Figure 5 A diagram for explaining the recording of abdominal sounds using the mobile information terminal 6 . Figure 6 This is a diagram showing an example of a situation in which the user is recording abdominal sounds using the portable information terminal 6 .

[0114] As shown in the figure, in the present embodiment, the user's abdominal sounds are recorded while the sound collecting part 6c near the microphone 81 in the frame 6b is in contact with the user's abdomen. At this time, the user is in a quiet state in a sitting posture such as sitting on a chair. It is preferred that the sound collecting part 6c is directly in contact with the skin of the abdomen. In addition, for adult users, the preferred contact part is a position that is only 9 cm away from the navel in any left or right direction. In the present embodiment, the user starts recording while pressing the sound collecting part 6c against the abdomen with a relatively weak force. When 60 seconds of recording is performed, the recording of the abdominal sounds ends.

[0115] Here, in this embodiment, when the user is sitting on a seat and the sound collecting part 6c has contacted the abdomen, it is preferred that the portable information terminal 6 is in a position with the touch screen 61 facing upward. Before, during or after recording, the user can confirm the display content of the touch screen 61. At this time, in order to obtain a higher quality recording result, it is preferred to hold the touch screen 61, i.e., the portable information terminal 6, in a position where the plane tangent to the surface of the abdomen at the contact point is approximately perpendicular. More specifically, on the surface of the abdomen, a line ( Figure 5The angle formed by the touch screen 61 (indicated by the symbol V in the figure) and the touch screen 61 (sometimes referred to as the pressing angle G of the portable information terminal 6) is preferably about 90 degrees.

[0116] Since the portable information terminal 6 is provided with the environment detection unit 41 and the recording processing unit 51 as described above, it is possible to perform detection related to the recording environment or processing according to the detection result as follows, for example.

[0117] First, the environment detection unit 41 can also perform detection related to the recording environment based on the sound information obtained by recording using the microphone 81. In addition, the sound information used at this time can be sound information that has been recorded for recording abdominal sounds, or it can be a recording of sound collected by the microphone 81 before recording abdominal sounds.

[0118] For example, the environment detection unit 41 may also be configured to perform detection based on the noise level or the SN ratio of abdominal sound to noise in the sound information obtained by recording using the microphone 81. For example, it may also be configured to detect that the environment is in an unsuitable environment (or not in an unsuitable environment) when the noise level is above a prescribed value or the SN ratio is above a prescribed value in the sound information. Furthermore, it may also be configured to detect that the environment is in a suitable environment (or not in an unsuitable environment) when the noise level is below a prescribed value or the SN ratio is below a prescribed value.

[0119] In this way, when it is detected that the environment is in an unsuitable environment or a suitable environment, the recording processing unit 51 may be configured to perform processing for acquiring sound information in a suitable environment in response to the detection.

[0120] In addition, for example, the environment detection unit 41 can also obtain information related to whether the mobile phone case has been installed in the frame 6b, and perform detection related to the recording environment based on the information obtained. For example, based on the sound information, the environment detection unit 41 can also obtain information related to whether the mobile phone case has been installed in the frame 6b. That is, when the mobile phone case has been installed in the frame 6b, although the details of the intestinal sounds tend to be improved, electromagnetic noise sometimes occurs in the sound information. When the mobile phone case is not installed, although the intestinal sounds sometimes have a tendency to be blocked, it is difficult to produce noise. It is believed that this is because when the mobile phone case has been installed, the frame 6b is easily in an electrically disconnected state due to the structure of the frame 6b or the mobile phone case used or its combination. Utilizing this point, in this embodiment, the environment detection unit 41 can be configured to detect the electromagnetic noise contained in the sound information, and obtain information related to whether the mobile phone case has been installed in the frame 6b based on the detection result of the electromagnetic noise. When the electromagnetic noise is large, information indicating that the mobile phone case has been installed can also be obtained. The environment detection unit 41 may also be configured to detect that the mobile phone case is not in a suitable environment when it is determined that the mobile phone case is installed in the frame 6b. Furthermore, the environment detection unit 41 may also detect that the mobile phone case is not in a suitable environment when it is determined that the mobile phone case is installed in the frame 6b, or detect that the mobile phone case is not in a suitable environment when it is determined that the mobile phone case is installed in the frame 6b.

[0121] The environment detection unit 41 can also obtain information related to whether the mobile phone case has been installed on the frame 6b when it is judged that the prescribed conditions related to the quality of the sound information are met. As the prescribed conditions, for example, the SN ratio is below the prescribed value or the level of electromagnetic noise is above the prescribed value. In addition, the environment detection unit 41 can also make a judgment based on the sound information obtained before the recording of the abdominal sound and the sound information in the recording. That is, for example, when the volume of the noise when the portable information terminal 6 is pressed against the abdomen before the start of the recording is above the prescribed value and the volume of the intestinal sound detected for the first time after the start of the recording is above the prescribed value, it can be judged that the mobile phone case has been installed. In addition, for example, in a prescribed frequency band above 500 Hz, when noise is detected for a prescribed time (for example, 5 seconds to 10 seconds), it can be regarded as electromagnetic noise and it can be judged that the mobile phone case has been installed.

[0122] In addition, when it is determined that the mobile phone case has been installed, the recording process being performed by the recording processing unit 51 can be terminated. In addition, the recording processing unit 51 can also perform a prescribed attention-calling display on the touch screen 61. That is, when it is detected that the mobile phone case has been installed in the frame 6b, the recording processing unit 51 performs an attention-calling display, thereby also notifying the user of the portable information terminal 6 to remove the mobile phone case. In addition, the attention-calling display can also be information asking the user whether the mobile phone case has been installed. In addition, the recording processing unit 51 can again perform a process to obtain information related to whether the mobile phone case has been installed in the frame 6b.

[0123] In addition, for example, the environment detection unit 41 can also be configured to obtain information related to the pressure of the portable information terminal 6 on the abdomen based on the sound information, and perform detection related to the recording environment based on the obtained information. It can also be said that the pressing force is the pressing pressure. In the present embodiment, the environment detection unit 41 can also detect the noise in the sound information and obtain information related to whether the pressing force is appropriate based on the detection result. That is, when the size of the noise in the sound information changes corresponding to the size of the pressing force, information related to whether the pressing force is appropriate can be obtained based on the size of the noise. For example, when the size of the noise is less than a specified value, information that the pressing force is appropriate can be obtained. In addition, when the size of the intestinal sounds in the sound information changes corresponding to the size of the pressing force, information related to whether the pressing force is appropriate can be obtained based on the size of the SN ratio. For example, when the size of the SN ratio is greater than a specified value, information that the pressing force is appropriate can be obtained.

[0124] The environment detection unit 41 may be configured to detect that the environment is suitable when the information that the pressing force is suitable is obtained, and to detect that the environment is not suitable when the information that the pressing force is not suitable is obtained. Furthermore, the environment detection unit 41 may express the judgment that the pressing force is suitable as the detection that the environment is suitable, or express the judgment that the pressing force is not suitable as the detection that the environment is not suitable.

[0125] Furthermore, when it is determined that the pressing force is not appropriate, the recording processing unit 51 may also terminate the recording in progress. In addition, at this time, the recording processing unit 51 may also perform a predetermined attention-calling display on the touch screen 61. Here, the attention-calling display may be information that guides the user to change the pressing force, or information that makes the user aware of reducing the pressing force. This is because in a normal quiet environment, if the pressing force is small, it can be expected that the noise will be reduced. In addition, when it is determined that the pressing force is appropriate, the recording processing unit 51 may output information that guides the user to maintain this state during the recording.

[0126] Furthermore, the environment detection unit 41 can also detect a more appropriate pressing force in order to obtain a higher quality recording result of the abdominal sounds. At this time, it is also possible to detect that the pressing force is most suitable when the SN ratio becomes the maximum during a specified period (for example, from the time when the portable information terminal 6 is pressed on the abdomen to the present). In other words, the environment detection unit 41 can also obtain information related to the current pressing force based on the past sound information and the current sound information, and perform detection related to the current pressing force based on the obtained information. When it is determined that the pressing force is most suitable, or when it is determined that it is not the most suitable pressing force (the SN ratio at the past moment is larger), the recording processing unit 51 can output information to let the user know the situation. Thus, the user can adjust the pressing force in a manner that maintains the state of outputting the information of the most suitable pressing force while recording the abdominal sounds.

[0127] Figure 7 This is a graph showing an example of the relationship between pressing pressure and noise level of sound information.

[0128] Figure 7 In the figure, the horizontal axis represents the magnitude of the pressing pressure, and the vertical axis represents the volume of intestinal sounds or noises. In an environment where there is a certain degree of ambient sound, the greater the pressing pressure, the smaller the ambient sound recorded as sound information. In addition, electromagnetic noise is generated when a mobile phone case is used, and the greater the pressing pressure, the greater its size. When there is no case, the size of the recorded intestinal sounds becomes maximum within a specified range (about 2N) where the pressing pressure is weak. In addition, on the other hand, when a mobile phone case is used, the size of the recorded intestinal sounds becomes maximum within a specified range (about 9N) where the pressing pressure is strong.

[0129] When there is such a relationship between the pressing force and the size of each sound, the environment detection unit 41 can also perform detection related to the most suitable pressing force as follows. That is, when there is no mobile phone case, for example, it can be determined that the pressing force with the largest SN ratio of the environmental sound to the intestinal sound is the most suitable. Figure 7 On the other hand, when there is a mobile phone case, for example, it can be determined that the pressing force with the largest SN ratio of ambient sound or electromagnetic noise to intestinal sound is the most suitable. Figure 7 In the relationship shown in FIG. 1 , it is known that the most suitable pressure is about 7 N to 9 N. Furthermore, when the mobile phone case is used, if the volume of the noise when the portable information terminal 6 is placed against the abdomen is greater than a predetermined value, it can also be determined that the pressing force is too strong.

[0130] In addition, for example, the environment detection unit 41 can also detect the environment of the recording based on information related to the posture of the recording device. In this embodiment, when the user is sitting on the seat and the sound collection unit 6c has contacted the abdomen, the environment detection unit 41 detects whether the angle (pressing angle G) formed by the line perpendicular to the plane tangent to the surface of the abdomen at the contact point and the touch screen 61 is within a specified angle range. For example, the acceleration sensor 91 can be used to detect the pressing angle G.

[0131] In this embodiment, the environment detection unit 41 obtains information on whether the pressing angle G is within a range of about 30 degrees and detects it. When the microphone 81 is configured to have high sensitivity to sounds from the downward direction, if the pressing angle G is within a predetermined angle range, it is possible to be in a suitable environment for recording intestinal sounds included in abdominal sounds with a loud sound.

[0132] Furthermore, the angle range of the pressing angle G is not limited thereto. For example, it may be within 20 degrees. When the portable information terminal 6 is pressed against the abdomen with the touch screen 61 facing upward, it can also be said that the pressing angle G is the inclination angle of the portable information terminal 6. It can also be said that the pressing angle G is the angle around an axis parallel to the left and right directions of the touch screen 61. In addition, it can also be said that the pressing angle is the inclination angle of the portable information terminal 6 from the upright posture. At this time, the environment detection unit 41 can also be configured, for example, to detect that the environment is suitable when the pressing angle is within the angle range of 70 to 120 degrees.

[0133] As described above, when the posture of the portable information terminal 6 is detected as being in a suitable environment, the recording processing unit 51 may be configured to output information to guide the user to maintain this state during recording.

[0134] Furthermore, the environment detection unit 41 can also be configured to detect whether the portable information terminal 6 is moving or stationary using the acceleration sensor 91, and when it is detected to be stationary, it is detected as being in a suitable environment. Thus, the abdominal sound can be recorded in a stable state, and a high-quality recording result of the abdominal sound can be obtained.

[0135] Furthermore, the environment detection unit 41 can also obtain the device identification information from the device identification information storage unit 13, and perform detection based on the obtained identifier. For example, regarding a specific model that is greatly affected by electromagnetic noise due to the presence or absence of a mobile phone case, the environment detection unit 41 can also detect the presence or absence of the mobile phone case as described above, and does not perform detection related to the presence or absence of the mobile phone case for other models. In this way, high-quality abdominal sound recording can be performed for each model of the portable information terminal 6.

[0136] Next, an example of the operation of the portable information terminal 6 and an example of the operation of the information processing device 100 performed when the user uses the information processing system 1 involved in this embodiment will be described. In this embodiment, for example, the user can connect to the information processing device 100 or receive information sent from the information processing device 100 through the portable information terminal 6, and use the information processing system 1 by running a predetermined application in the portable information terminal 6. In addition, the predetermined application may be, for example, a dedicated application that is run using information sent from the information processing device 100, or a web browser that displays a web application provided in the information processing device 100 as available for use.

[0137] In the present embodiment, the information processing system 1 is typically used as follows. That is, the user uses the portable information terminal 6 to record the sound of his or her own abdomen. In this way, the sound information is sent from the portable information terminal 6 to the information processing device 100, and the information processing device 100 obtains the bowel score. The information processing device 100 sends (outputs) the obtained bowel score to the portable information terminal 6. The portable information terminal 6 receives the bowel score and displays the information including the bowel score on the display device through the terminal output unit 60. Thus, the user can confirm the information related to his or her own intestine as a bowel score. When such an information processing system 1 is operated, the portable information terminal 6 and the information processing device 100 perform various actions, for example, as follows. The terminal processing unit 40 or the processing unit 140 performs control actions while using each part, thereby performing these actions.

[0138] Figure 8 This is a flowchart showing an example of the operation of the information processing device 100 .

[0139] (Step S61) The terminal processing unit 40 receives an instruction to execute a recording function for recording abdominal sounds. For example, when an instruction to start a predetermined application program or an operation to select a predetermined operation mode is performed, the terminal processing unit 40 receives an instruction to execute the recording function.

[0140] In order to perform recording, the user sits on a seat and presses the sound collecting unit 6 c of the portable information terminal 6 against the abdomen.

[0141] (Step S62) The terminal processing unit 40 determines whether the detection of being in a suitable environment has been performed. Here, for example, when any of the conditions of the ambient sound being less than a specified value, the portable information terminal 6 being in a substantially stationary state, and the portable information terminal 6 being in a specified posture (the pressing angle G is within a specified angle range) is satisfied, it is detected that the environment is suitable. If the detection of being in a suitable environment has been performed, the process proceeds to step S64, otherwise it proceeds to step S63.

[0142] (Step S63) The terminal processing unit 40 outputs a guidance display indicating that the device is not in a suitable environment. For example, the information is output to the touch screen 61. Then, the process returns to step S62.

[0143] (Step S64) The terminal processing unit 40 controls the portable information terminal 6 in a manner that can accept the start instruction from the user. For example, an operation button for starting the recording of abdominal sounds (for starting the recording as sound information) is enabled on the operation interface displayed on the touch screen 61. For example, the display state may be changed by making the inactive state appear or cancel, and the behavior when the operation button is operated may be changed.

[0144] (Step S65) The terminal processing unit 40 determines whether a start instruction from the user has been accepted. The terminal processing unit 40 waits until a start instruction is accepted, and if a start instruction has been accepted, the process proceeds to step S66.

[0145] (Step S66) The terminal processing unit 40 performs pre-recording. The pre-recording is performed only for a predetermined time (for example, 30 seconds). Although the sound information obtained by the pre-recording is included in the sound information finally used for obtaining the bowel score, it may not be used for obtaining the bowel score.

[0146] (Step S67) The terminal processing unit 40 determines whether the detection of being in a suitable environment has been performed based on the sound information obtained by pre-recording. Here, for example, when the conditions of appropriate pressing force and the magnitude of electromagnetic noise being below a specified value are satisfied, it is detected that the environment is suitable. When it is detected that the environment is suitable, the process proceeds to step S69, otherwise it proceeds to step S68.

[0147] (Step S68) The terminal processing unit 40 interrupts the recording and outputs a guidance display about not being in a suitable environment. For example, the information is output to the touch screen 61. Then, the process returns to step S65. In addition, the process may return to other processes or end a series of processes.

[0148] (Step S69) The terminal processing unit 40 performs formal recording. The formal recording is performed only for a specified time (for example, 30 seconds). Thus, together with the pre-recording, the recording result of the abdominal sound for the time required for scoring is obtained. In addition, only the result of the formal recording can be processed as sound information for obtaining the intestinal score.

[0149] Furthermore, during the pre-recording and the actual recording, a display about the recording status can be output to the touch screen 61 so that the user can visually recognize the output terminal processing unit 40. The display about the recording status can be, for example, a display indicating the progress status (for example, a display indicating the remaining time or a progress bar, etc.). In addition, the display about the recording status can be a waveform indicating the content of the sound information that has been recorded. By performing such a display, the user can easily maintain the static state required for recording high-quality abdominal sounds.

[0150] (Step S70) The terminal processing unit 40 transmits the voice information to the information processing device 100. If the voice information cannot be transmitted satisfactorily due to communication failure, a display may be made to suggest the user to move to another place or change the communication method.

[0151] Thus, when the sound information is transmitted to the information processing device 100, the information processing device 100 acquires the bowel score using the sound information, and information related to the acquired bowel score is transmitted from the portable information terminal 6 to the information processing device 100.

[0152] (Step S71) The terminal processing unit 40 determines whether or not it has received information on the score transmitted from the information processing device 100. The terminal processing unit 40 waits until the information is received, and if the information is received, the process proceeds to step S72.

[0153] (Step S72) The terminal processing unit 40 uses the received score-related information to output a display related to the bowel score, etc. to the touch screen 61. This allows the user to know his or her own bowel score or information related thereto, etc. Thereafter, a series of processing ends.

[0154] Furthermore, in the process of detecting the above-mentioned suitable environment, the condition for detecting being in a suitable environment may be a combination of the above-mentioned multiple conditions or a condition related to only one point of view. For example, in step S62, being in a suitable environment may be detected based on the result of judging only the size of the ambient sound.

[0155] In addition, it is also possible to determine whether the abdominal sounds include intestinal sounds based on the results of the pre-recording or the results of the formal recording, and when there is an abnormality such as the sound determined to be intestinal sounds exceeding a predetermined volume, the user is notified of the situation, or a suggestion is made to re-record. The presence or absence of such an abnormality can be determined in the portable information terminal 6 based on the sound information obtained in step S66 or step S69, or the sound information can be sent to the information processing device 100, and the result determined in the information processing device 100 can be fed back to the portable information terminal 6.

[0156] Furthermore, since the portable information terminal 6 is configured to perform such an action, the recording method for recording the abdominal sounds of the user using the portable information terminal 6 may include the following steps. That is, first, when the user is sitting on a seat, the user touches the sound collecting unit 6c to the user's abdomen (first step). Next, when the sound collecting unit 6c has touched the abdomen, the terminal processing unit 40 performs a detection of a suitable environment through the environment detection unit 41 (second step). In other words, when the sound collecting unit 6c has touched the abdomen, the user performs a detection of a suitable environment through the portable information terminal 6. Afterwards, the terminal processing unit 40 causes the recording processing unit 51 to perform processing related to the recording based on the detection result of the environment detection unit 41 (third step). In other words, the user performs processing related to the recording corresponding to the detection result through the portable information terminal 6. By adopting such a recording method, a high-quality recording result is obtained.

[0157] Fig. 9 This is a flowchart showing an example of the operation of the information processing device 100 .

[0158] (Step S11) The processing unit 140 determines whether information transmitted from the portable information terminal 6 or the like has been received through the receiving unit 120. If it is determined that the information has been received, the process proceeds to step S12, otherwise the process proceeds to step S13.

[0159] (Step S12) The processing unit 140 identifies the user based on the received information, and accumulates the received information in the user information storage unit 115 in correspondence with the user identifier. For example, when the portable information terminal 6 sends life information, voice information, or device identification information in correspondence with the user identifier, the processing unit 140 accumulates the received information in the user information storage unit 115 in correspondence with the user identifier.

[0160] (Step S13) The processing unit 140 determines whether an opportunity for obtaining a bowel score has occurred. In other words, the processing unit 140 determines whether a condition for starting to obtain a bowel score has been met. If it is determined that an opportunity has occurred, the process proceeds to step S14. Otherwise, the process returns to step S11.

[0161] Furthermore, for example, the user's instruction to obtain a bowel score (sending of prescribed information corresponding to the instruction) through the portable information terminal 6 can be used as the above-mentioned trigger, but the trigger is not limited to this. For example, the arrival of a prescribed time or the receipt of new voice information or other life information can be used as the trigger when various conditions are met.

[0162] (Step S14) The processing unit 140 performs a score acquisition process via the intestinal score acquisition unit 149. The score acquisition process will be described later. The intestinal score or each element score is acquired via the score acquisition process and accumulated in the user information storage unit 115.

[0163] (Step S15) The processing unit 140 constructs information to be output using the acquired bowel scores, etc., through the bowel score output unit 161. In the present embodiment, information for indicating the bowel score and information for indicating each element score as a radar chart are constructed.

[0164] (Step S16) The processing unit 140 outputs the constructed information to the target user through the bowel score output unit 161. That is, the processing unit 140 outputs the constructed information about the bowel score and each element score to the portable information terminal 6 used by the user who is the target of score calculation through the transmission unit 170. As a result, the portable information terminal 6 that has received the information can display the bowel score and each element score.

[0165] Next, a specific example of recording abdominal sounds according to the present embodiment will be described while showing the screen transition of the portable information terminal 6 used by the user.

[0166] In the following specific example, it is assumed that the information processing system 1 provides a health support application for supporting the user to live a healthy life. The health support application accepts input operations related to the user's life information and provides the user with information useful for maintaining health. The user executes a predetermined application in the portable information terminal 6, and the portable information terminal 6 communicates with the information processing device 100, thereby realizing the health support application. Under the control of the terminal processing unit 40, the terminal output unit 60 displays the following screen example of the health support application.

[0167] The user can record his / her own abdominal sounds for obtaining a bowel score by performing a predetermined operation while executing the health support application.

[0168] Fig.10 FIG. 1 is a first diagram showing a specific example of screen transition of the portable information terminal 6. FIG.

[0169] Fig.10 In step S91, a recording preparation screen 901 for recording in the health support application is displayed. The recording preparation screen 901 includes, for example, a display that guides the user to press the portable information terminal 6 against the abdomen after sitting down for recording. The user makes the prescribed preparations according to the display content of the recording preparation screen 901, and by operating the recording button 905, the next screen can be transferred to the execution of recording.

[0170] In the example shown in the figure, the recording preparation screen 901 includes an environment information display 903 indicating the measurement result of the ambient sound and the detection result of being in a suitable environment. As a result, regarding the ambient sound, the user can easily know the information related to whether it is in a suitable environment and the magnitude of the ambient sound. In addition, the display form of the environment information display 903 can be changed when it is detected as being in a suitable environment and when it is not detected as being in a suitable environment. In addition, it can also be configured so that the operation of the recording button 905 can be accepted only when it is detected as being in a suitable environment.

[0171] If the recording button 905 is operated, the screen 911 for recording start is displayed (step S92). In the recording start instruction screen 911, the recording start button 915 is initially displayed in an inactive (non-operation-acceptable) state. Alternatively, the recording start button 915 may not be displayed at the beginning. When the recording start instruction screen 911 is displayed, if the posture or activity of the portable information terminal 6 is detected as being in an appropriate environment as described above, the recording start button 916 is displayed in an operable state (step S93).

[0172] Thus, the user can start recording abdominal sounds by operating recording start button 916. Since recording of abdominal sounds is started when it is detected that the environment is suitable, a high-quality recording result of abdominal sounds can be obtained reliably.

[0173] Fig.11 FIG. 2 is a second diagram showing a specific example of screen transition of the portable information terminal 6. FIG.

[0174] Fig.11 In step S95, a recording screen 931 is displayed when the abdominal sound is being recorded. In the recording screen 931, a recording progress display 933 and a recording waveform display 934 are displayed as displays about the recording status. As the recording progress display 933, for example, a display indicating the remaining time and a progress bar indicating the progress degree are displayed, but it is not limited to these. The recording waveform display 934 is a waveform indicating the content of the sound information that has been recorded, and the user can recognize that the recording is in progress with a sense of reality.

[0175] In the example shown in the figure, the recording screen 931 includes a display related to the recording status, so that the user's attention during recording is drawn, and unnecessary activities of the user, which is one of the main causes of recording quality degradation, can be prevented. In addition, since the user can confirm the progress, he can wait for the recording to end with peace of mind.

[0176] Here, during recording, when it is detected that the environment is not suitable, the error screen 941 is switched (step S96). For example, based on the sound information indicating the recording result of the pre-recording, when it is detected that the noise is large or the pressing force is not suitable, the error screen 941 can be switched. The error screen 941 may include guidance on indicating that the recording has been terminated or the reason and countermeasures. The user can face the recording again after confirming the content of the error screen 941.

[0177] On the other hand, when the recording is performed normally, the sound information is sent to the information processing device 100, and the intestinal score is sent from the information processing device 100 to the portable information terminal 6. If the portable information terminal 6 receives the intestinal score, it transitions to the result display screen 951 (step S97). The result display screen 951, for example, shows the intestinal score that has been obtained and information related thereto (for example, information showing a ranking classified by the degree of intestinal activity, etc.). By confirming the content of the result display screen 951, the user can recognize the objective evaluation related to the state of his or her own intestine and use it in daily life.

[0178] As described above, in this embodiment, the portable information terminal 6 is used to perform processing on the recording according to the detection result of being in a suitable environment, so that a high-quality recording result of abdominal sounds can be obtained. When it is not in a suitable environment, a corresponding display is performed on the touch screen 61, so that the user can be prompted to record in a more suitable environment. In addition, although the recording result is of high quality, specifically, it means that the SN is relatively high, it is not limited to this. For example, it can also indicate that the level of abdominal sounds is high, the level of noise is low, or the state of other abdominal sounds (especially intestinal sounds) can be more clearly grasped.

[0179] The information processing device 100 uses high-quality sound information to obtain a bowel score related to the state of the user's intestines, and outputs the obtained bowel score, so that a bowel score that accurately represents the state of the user's intestines can be output. By outputting such a bowel score, the user can easily know objective information related to the state of his or her own intestines, which is information that can be easily grasped.

[0180] Furthermore, although it is preferred that the storage unit 110 and the terminal storage unit 10 are non-volatile storage media, they can also be implemented using volatile storage media. These respectively store information etc. that has been acquired in their respective devices, but the process of storing information etc. is not limited to this. For example, information etc. can be stored by a storage medium, information etc. sent by a communication line etc. can be stored, or information etc. input by an input device etc. can be stored.

[0181] In addition, the above-mentioned processing unit 140 or terminal processing unit 40 can usually be realized by MPU or memory, etc. Usually, the processing sequence of the processing unit 140 or terminal processing unit 40 is realized by software, and the software is recorded in a storage medium such as ROM. However, it can also be realized by hardware (dedicated circuit).

[0182] In addition, the input means that can be used to input information that can be accepted by the acceptance unit 130 or the terminal acceptance unit 30 may be any one of a numeric keypad, a keyboard, a mouse, a menu screen, etc. The acceptance unit 130 or the terminal acceptance unit 30 can be implemented by a device driver of an input means such as a numeric keypad or a keyboard, or control software of a menu screen, etc.

[0183] In addition, although the receiving unit 120 or the terminal receiving unit 20 is usually realized by wireless or wired communication means, it is also possible to realize it by means of receiving broadcasts.

[0184] In addition, although the transmission unit 170 or the terminal transmission unit 70 is usually realized by wireless or wired communication means, it can also be realized by broadcasting means.

[0185] Furthermore, the information processing device 100 may be composed of one server, or a plurality of servers working in cooperation with each other, or may be an electronic computer built into other equipment, etc. Furthermore, the server may be a so-called cloud server, or an ASP server, etc., and needless to say, the server may be of any type.

[0186] In addition, part or all of the components provided in the information processing device 100 in the above contents may also be provided in the portable information terminal 6. That is, the portable information terminal 6 may also have part or all of the structure for realizing the function related to the acquisition and output of the bowel score as provided in the above information processing device 100. For example, the portable information terminal 6 may also be configured to acquire the bowel score using the sound information recorded in the portable information terminal 6. On the other hand, part of the components provided in the portable information terminal 6 in the above contents may also be provided in the information processing device 100. That is, the information processing device 100 may also have part of the structure for realizing the detection of whether it is in a suitable environment or the processing related to the recording corresponding thereto as provided in the above portable information terminal 6. For example, the information processing device 100 may also be configured to perform processing such as determining noise using the sound information recorded in the portable information terminal 6, or to send a recording start instruction or a recording interruption instruction based on the detection result of the suitable environment to the portable information terminal 6.

[0187] The processing in this embodiment can also be implemented by software. Moreover, the software can also be distributed by software downloading, etc. In addition, the software can also be recorded on a storage medium such as a CDROM and distributed.

[0188] Furthermore, the software that realizes the information processing device 100 in the present embodiment is the following program. That is, the program is a program that causes a computer to function as a sound information acquisition unit that acquires sound information related to the sound emitted from the abdomen of a user, that is, abdominal sound, a bowel score acquisition unit, and an output unit, the sound information acquisition unit acquires sound information related to the state of the user's intestines by using input information including the sound information acquired by the sound information acquisition unit and learning information prepared in advance, and the output unit outputs the bowel score acquired by the bowel score acquisition unit.

[0189] In addition, the software that realizes the recording device in this embodiment, that is, the portable information terminal 6, is the following program. That is, the program is executed in the computer of the recording device, and makes the computer of the recording device function as an environment detection unit and a recording processing unit.

The environment detection unit detects at least one of an unsuitable environment unsuitable for recording abdominal sound and a suitable environment suitable for recording. The recording processing unit performs processing related to the recording according to the detection result of the environment detection unit.
