[0011] The following describes exemplary embodiments of the present disclosure. The configurations of the embodiments described below, as well as the actions and effects achieved by the configurations, are merely examples.
[0012] 1A and 1B are schematic diagrams showing an example of the external configuration of an information processing device 10 according to this embodiment.
[0013] The information processing device 10 is an information processing device for outputting physical condition information related to the physical condition of a user based on the user's pulse wave. The information processing device 10 is a dedicated or general-purpose computer. In this embodiment, an example will be described in which the information processing device 10 is a mobile terminal such as a smartphone that can be carried by a user. Note that the information processing device 10 is not limited to a mobile terminal such as a smartphone. Furthermore, the information processing device 10 is not limited to a smartphone, and may be a smartwatch or the like that is worn on the user's wrist.
[0014] Fig. 1A is a schematic diagram of the first surface P1 side of the information processing device 10. Fig. 1B is a schematic diagram of the second surface P2 side of the information processing device 10. The first surface P1 and the second surface P2 are surfaces that constitute the housing of the information processing device 10 and are surfaces that face each other.
[0015] 1A, an imaging unit 13 and a pulse wave sensor 16 are provided on the first surface P1 side of the information processing device 10. The imaging unit 13 acquires captured image data by capturing an image. The pulse wave sensor 16 is a sensor that detects the pulse wave of the user. Details of the pulse wave sensor 16 will be described later.
[0016] As shown in FIG. 1B , a UI (user interface) unit 15 is provided on the second surface P2 of the information processing device 10. The UI unit 15 has a function of accepting operation inputs by a user and a function of displaying various information. In this embodiment, the UI unit 15 includes a display device 15A and an input device 15B. The display device 15A is a display that displays various information. The input device 15B accepts various operations by a user. The input device 15B is a position input device such as a touchpad, a keyboard, a pointing device, a mouse, an input button, or the like. Note that the display device 15A and the input device 15B may be integrally configured to configure the UI unit 15 as a touch panel. In this embodiment, a configuration in which the UI unit 15 is a touch panel will be described as an example.
[0017] FIG. 2 is a functional block diagram of an example of the information processing device 10 of this embodiment.
[0018] Information processing device 10 includes communication unit 11, storage unit 12, imaging unit 13, audio input / output unit 14, UI unit 15, pulse wave sensor 16, and processing unit 17. Communication unit 11, storage unit 12, imaging unit 13, audio input / output unit 14, UI unit 15, pulse wave sensor 16, and processing unit 17 are connected to each other so as to be able to exchange data and signals.
[0019] The communication unit 11 communicates with other information processing devices directly or via a network, wirelessly or via a wire.
[0020] The storage unit 12 stores various types of information. In this embodiment, the storage unit 12 stores an index management DB (database) 12A, a personal standard 12B, criteria information 12C, a physical condition information management DB 12D, etc. Details of this information will be described later.
[0021] The audio input / output unit 14 is a device for inputting and outputting audio, and includes, for example, a microphone, a speaker, and the like.
[0022] Pulse wave sensor 16 is a sensor that measures the user's pulse wave. Pulse wave sensor 16 includes an LED (Light Emitting Diode) 16A and a light receiving unit 16B. LED 16A is an example of a light emitting unit that emits light. In this embodiment, LED 16A includes an IR (infrared)-LED 16A1 and a Green-LED 16A2.
[0023] The light receiving unit 16B receives light irradiated from the IR-LED 16A1 and reflected by the user's measurement target area, and outputs a pulse wave signal of the pulse wave represented by a transition in the output value according to the amount of light received to the processing unit 17.
[0024] In this embodiment, an example will be described in which the information processing device 10 treats the transition in output value corresponding to the amount of light received by the user's measurement target area from light irradiated by the IR-LED 16A1 and reflected by the user's measurement target area as a pulse wave signal. However, the information processing device 10 may treat the transition in output value corresponding to the amount of light received by the user's measurement target area from light irradiated by the Green-LED 16A2 as a pulse wave signal. Alternatively, the information processing device 10 may treat the amount of light received by the user's measurement target area from the reflected light irradiated by the Green-LED 16A2 as a pressure value applied to the pulse wave sensor 16 on the user's measurement target area.
[0025] The measurement target area is an area of the user whose pulse wave is measured by pulse wave sensor 16. In this embodiment, the measurement target area is described assuming that the measurement target area is the user's fingertip. However, the measurement target area is not limited to the fingertip, and may be any area of the user whose pulse wave can be measured by pulse wave sensor 16. For example, the measurement target area may be the user's wrist, inside of the wrist, finger joints, forehead, between the eyebrows, tip of the nose, cheek, under the eyes, temples, earlobes, etc.
[0026] Note that pulse wave sensor 16 may be any sensor that detects the user's pulse wave, and its configuration is not limited to the above. For example, pulse wave sensor 16 may be a transmission type sensor that receives light emitted from LED 16A and transmitted through the user's body with light receiving unit 16B.
[0027] Processing unit 17 executes information processing in information processing device 10. Processing unit 17 includes a display control unit 17A, a receiving unit 17B, a pulse wave acquiring unit 17C, a derivation unit 17D, a memory control unit 17E, a determination unit 17F, a calculation unit 17G, and a comparison unit 17H.
[0028] At least a portion of the display control unit 17A, the reception unit 17B, the pulse wave acquisition unit 17C, the derivation unit 17D, the memory control unit 17E, the judgment unit 17F, the calculation unit 17G, and the comparison unit 17H may be realized, for example, by having a processing device such as a CPU (Central Processing Unit) execute a program, i.e., by software, or by hardware such as an IC (Integrated Circuit), or by a combination of software and hardware.
[0029] The display control unit 17A displays various types of information on the display device 15A. The display device 15A may be provided in an external device communicatively connected to the information processing device 10 via the communication unit 11 or the like. The display device 15A may also be provided in both the information processing device 10 and the external device. In this embodiment, a form in which the display control unit 17A displays various types of information on the display device 15A of the information processing device 10 will be described as an example.
[0030] When the information processing program of this embodiment is executed, the display control unit 17A displays, for example, an initial screen on the display device 15A.
[0031] 3A is a schematic diagram of an example of a display screen 20A. The display screen 20A is an example of the display screen 20 displayed on the display device 15A. The display screen 20A is also an example of an initial screen.
[0032] Display screen 20A includes selection buttons for accepting selection of the type of measurement. The selection buttons are display areas for accepting selection by the user.
[0033] The type of measurement indicates the type of pulse wave measurement, and in this embodiment, the types of measurement include my standard measurement and spot measurement.
[0034] The my-standard measurement is a measurement for obtaining a pulse wave used to derive the user's standard index.
[0035] The standard index is information that serves as a standard for an index related to the autonomic nerves of the user. In this embodiment, the standard index may be referred to as a "my standard."
[0036] The measurement indexes derived by the process described below based on the pulse wave measured when the "My Standard Measurement" is selected are used to derive the user's standard index ("My Standard"). Details of the measurement indexes will be described later.
[0037] A spot measurement is a measurement for obtaining information about the pulse wave that is not used to derive the user's standard indices.
[0038] The display screen 20A includes a My Standard Measurement selection button 20A1 and a Spot Measurement selection button 20A2 as selection areas for accepting the selection of the type of measurement. The My Standard Measurement selection button 20A1 is a selection button for accepting the selection of My Standard Measurement. The Spot Measurement selection button 20A2 is a selection button for accepting the selection of Spot Measurement.
[0039] Display screen 20A may also include message information 20A5 and 20A6 for the user regarding the measurement. Display screen 20A also includes next button 20A3 for receiving an instruction from the user to transition to the next screen. Next button 20A3 is an example of a selection button.
[0040] Returning to Figure 2, we continue the explanation.
[0041] The reception unit 17B receives an operation instruction for the UI unit 15 from the user.
[0042] The user operates the UI unit 15 to select the My Standard Measurement selection button 20A1 or the Spot Measurement selection button 20A2 included in the display screen 20A, which is the initial screen shown in Fig. 3A, and then operates the Next button 20A3. When these operations are performed, the accepting unit 17B accepts measurement type information indicating the type of measurement, either the My Standard Measurement or the Spot Measurement, that has been selected.
[0043] Pulse wave acquirer 17C acquires the user's pulse wave. Pulse wave acquirer 17C receives the user's pulse wave signal from pulse wave sensor 16 and acquires the pulse wave represented by the pulse wave signal.
[0044] When reception unit 17B receives the measurement type information, pulse wave acquisition unit 17C transmits a pulse wave measurement start instruction signal to pulse wave sensor 16. Pulse wave acquisition unit 17C may transmit a pulse wave measurement start instruction signal to pulse wave sensor 16 when reception unit 17B receives pulse wave measurement instruction information as a result of a user operating UI unit 15 to instruct pulse wave measurement.
[0045] Upon receiving the pulse wave measurement start command signal, pulse wave sensor 16 irradiates a measurement target area, such as the user's fingertip, with IR light from IR-LED 16A1, and receives the IR light reflected by the measurement target area with light receiving unit 16B. Light receiving unit 16B then outputs to processing unit 17 a pulse wave signal of the pulse wave, which is represented by a transition in output value according to the amount of received light.
[0046] Pulse wave acquiring unit 17C acquires the pulse wave represented by the pulse wave signal by receiving the pulse wave signal transmitted from pulse wave sensor 16. Note that pulse wave acquiring unit 17C may acquire the pulse wave by analyzing the measurement target region of the user included in the captured image captured by imaging unit 13 using a known method.
[0047] While pulse wave sensor 16 is measuring the pulse wave, display control section 17A displays display screen 20 indicating that measurement is in progress on display device 15A.
[0048] 3B is a schematic diagram of an example of a display screen 20B that is displayed on the display device 15A during measurement of the pulse wave.
[0049] Display screen 20B includes message 20B1 indicating that pulse wave measurement is in progress, message 20B3 indicating precautions for the user during pulse wave measurement, information 20B2 indicating recommended posture for the user during pulse wave measurement, and message 20B6 indicating a recommendation for personal standard measurement. Display screen 20B also includes waveform image 20B7 that schematically depicts the pulse wave represented by the pulse wave signal received during pulse wave measurement. Display control unit 17A may also display image 20B4, which represents the ratio of the current elapsed measurement time to the standard time, on, for example, circular image 20B5 that represents the standard time required for pulse wave measurement.
[0050] Returning to Figure 2, we continue the explanation.
[0051] When pulse wave acquiring section 17C acquires the pulse wave of the user, display control section 17A displays display screen 20 for accepting input of tag information on display device 15A.
[0052] 3C is a schematic diagram of an example of display screen 20C. Display screen 20C includes information 20C1 indicating the currently selected type of measurement, an input field 20C2 for tag information, and a next button 20C4.
[0053] Tag information is information about the user that can be used as a tag for a measurement index, which will be described later. Used as a tag means that the information is used to classify the measurement index, which will be described later. The tag information input field 20C2 includes multiple tag button images 20C2a each having a different tag, an input field 20C2b for inputting the user's current mood, and an input field 20C2c for accepting free input by the user.
[0054] The reception unit 17B receives, as tag information, information obtained by the user operating the input device 15B to select at least one of the user's desired tag button image 20C2a, input into the input field 20C2b for inputting the user's current mood, and input into the input field 20C2c for accepting free input by the user.
[0055] Returning to Figure 2, we continue the explanation.
[0056] Derivation unit 17D derives a first index, a second index, and a third index based on the frequency spectrum of the user's pulse wave acquired by pulse wave acquisition unit 17C.
[0057] 4A and 4B are explanatory diagrams of an example of index calculation by derivation unit 17D. FIG. 4A is an example of a pulse wave 30 represented by a pulse wave signal acquired by pulse wave acquisition unit 17C. The horizontal axis of FIG. 4A represents time, and the vertical axis represents the pulse wave sensor output value. Pulse wave 30 is sometimes referred to as a pulse waveform. FIG. 4B is a frequency spectrum 32 of pulse wave 30. The horizontal axis of FIG. 4B represents frequency, and the vertical axis represents intensity. The unit of intensity is, for example, ms 2 is expressed by
[0058] The derivation unit 17D performs frequency analysis on the pulse wave 30 to obtain a frequency spectrum 32. For the frequency analysis, for example, an FFT (Fast Fourier Transform) or the like is used. The frequency spectrum 32 is sometimes called a power spectrum.
[0059] The derivation unit 17D derives a first index G1, a second index G2, and a third index G3 based on the frequency spectrum 32.
[0060] The first index G1 is an index representing the total amount of autonomic nervous activity of the user. The total amount of autonomic nervous activity is the total amount of autonomic nervous activity of the user, and is expressed by the total amount of sympathetic nervous activity and parasympathetic nervous activity, for example. In other words, the total amount of autonomic nervous activity of the user represents the ability to control the functions of the user's entire body.
[0061] The second index G2 is an index that represents the amount of sympathetic nervous activity of the user.
[0062] The third index G3 is an index that indicates the amount of parasympathetic nerve activity of the user.
[0063] The derivation unit 17D derives a first index G1 representing the total amount of autonomic nerve activity based on the integral of the intensities of all frequency band components included in the frequency spectrum 32 of the user's pulse wave 30. Specifically, the derivation unit 17D calculates the integral of the intensities of all frequency band components included in the frequency spectrum 32 of the user's pulse wave 30 as the first index G1. The derivation unit 17D may also calculate the sum of the intensities of all frequency band components included in the frequency spectrum 32 as the first index G1. The derivation unit 17D may also calculate the sum of the second index G2 and the third index G3 as the first index G1. The derivation unit 17D may also calculate the sum of the second index G2 and the third index G3 as the first index G1. The derivation unit 17D may also weight at least one of the second index G2 and the third index G3 and then calculate the sum as the first index G1. The weighting value used for this weighting may be calculated in advance from statistical values or the like. The weighting value used for this weighting may also be changeable as appropriate by the user's operation instruction via the input device 15B or the like.
[0064] Furthermore, the derivation unit 17D derives a second index G2 representing the amount of sympathetic nerve activity based on the integral value of the intensities of low frequency band components included in the frequency spectrum 32. In particular, the derivation unit 17D calculates, as the second index G2, the integral value of the intensities of the low frequency band components included in the frequency spectrum 32 of the user's pulse wave 30. Note that the derivation unit 17D may also calculate, as the second index G2, the sum of the intensities of the low frequency band components included in the frequency spectrum 32.
[0065] The low frequency band components are components in a frequency band that is at least less than the first frequency F1 across all frequencies in the frequency spectrum 32. Alternatively, the low frequency band components may be components in a frequency band that is equal to or greater than the fourth frequency F4 and less than the first frequency F1 across all frequencies in the frequency spectrum 32. For example, the fourth frequency F4 is 0.03 Hz, and the first frequency F1 is 0.15 Hz.
[0066] Furthermore, the derivation unit 17D derives a third index G3 representing the amount of parasympathetic nerve activity based on the integral value of the intensities of high frequency band components included in the frequency spectrum 32. In particular, the derivation unit 17D calculates the integral value of the intensities of the high frequency band components included in the frequency spectrum 32 of the user's pulse wave 30 as the third index G3. Note that the derivation unit 17D may also calculate the sum of the intensities of the high frequency band components included in the frequency spectrum 32 as the third index G3.
[0067] The high frequency band components are components in a frequency band equal to or greater than a second frequency F2 across all frequencies in the frequency spectrum 32. The second frequency F2 may be the same as or different from the first frequency F1. The high frequency band components may also be components in a frequency band equal to or greater than the second frequency F2 and less than a third frequency F3 across all frequencies in the frequency spectrum 32. For example, the second frequency F2 is 0.15 Hz, and the third frequency F3 is 0.50 Hz.
[0068] Furthermore, the derivation unit 17D may derive a predetermined first ratio of the integrated value of the intensity of the low-frequency band components included in the frequency spectrum 32 as the second index G2 representing the amount of sympathetic nerve activity. In this case, the derivation unit 17D may derive, as the third index G3 representing the amount of parasympathetic nerve activity, the sum of the integrated value of the intensity of the high-frequency band components included in the frequency spectrum 32 and the subtraction result obtained by subtracting the first ratio from the integrated value of the intensity of the low-frequency band components included in the frequency spectrum 32. The first ratio may be determined in advance. Furthermore, the first ratio may be changeable as appropriate in response to an operation instruction from the UI unit 15 by the user, or the like.
[0069] Returning to Figure 2, we continue the explanation.
[0070] The memory control unit 17E controls the storage of various types of information in the memory unit 12. When the derivation unit 17D derives the first index G1, the second index G2, and the third index G3 based on the frequency spectrum 32 of the user's pulse wave 30, the memory control unit 17E stores these measurement indexes in the index management DB 12A. The measurement index is a collective term for the first index G1, the second index G2, and the third index G3.
[0071] FIG. 5 is a schematic diagram showing an example of the data configuration of the index management DB 12A.
[0072] The index management DB 12A is a database for managing information related to the measured pulse wave 30 for each measurement timing. The data format of the index management DB 12A is not limited to a database. In detail, the index management DB 12A is a database that associates measurement dates and times, measurement types, measurement indexes, and tag information.
[0073] The measurement date and time is the timing at which the pulse wave 30 was measured. The measurement date and time may be either the start timing or the end timing of measurement of the pulse wave 30. As described above, the type of measurement indicates my standard measurement M or spot measurement S. The measurement indexes include a first index, a second index, and a third index derived by the derivation unit 17D for each measured pulse wave 30.
[0074] Each time the user's pulse wave 30 is measured by the pulse wave sensor 16, the memory control unit 17E associates the measurement date and time of the pulse wave 30, the type of measurement, the measurement index derived by the derivation unit 17D based on the pulse wave 30, and the tag information input by the user when the pulse wave 30 was measured, and registers them in the index management DB 12A.
[0075] Returning to Figure 2, we continue the explanation.
[0076] The judgment unit 17F judges whether or not the my standard measurement M has been performed multiple times. The judgment unit 17F judges whether or not the my standard measurement M has been performed multiple times by judging whether or not multiple measurement indices associated with the measurement type "my standard measurement" are stored in the index management DB 12A.
[0077] When it is determined that the my standard measurement M has been performed multiple times, the calculation unit 17G calculates the my standard (standard index).
[0078] FIG. 6 is an explanatory diagram of an example of my standards.
[0079] My Standard, which is a standard index, includes a first standard index, a second standard index, and a third standard index.
[0080] The first standard index is an index representing a standard value of the total amount of autonomic nervous activity of the user. The second standard index is an index representing a standard value of the amount of sympathetic nervous activity of the user. The third standard index is an index representing a standard value of the amount of parasympathetic nervous activity of the user.
[0081] The calculation unit 17G calculates the my standard using measurement indices (first index, second index, third index) derived based on the pulse wave 30 obtained by performing the my standard measurement M multiple times.
[0082] In this embodiment, the calculation unit 17G reads the first index, the second index, and the third index derived for each of a plurality of pulse waves 30 measured at different measurement dates and times within a predetermined period. Then, the pulse wave acquisition unit 17C calculates the average values of the first index, the second index, and the third index at different measurement dates and times as the first standard index, the second standard index, and the third standard index, respectively.
[0083] The method for calculating the My Standard will be specifically described with reference to FIGS.
[0084] For example, assume that the latest (current) measurement date and time is "2024 / 10 / 6 / 6:30" in the index management DB 12A. In this case, the calculation unit 17G excludes the measurement index associated with the latest measurement date and time and the measurement type "My Standard Measurement" from the My Standard calculation targets.
[0085] The calculation unit 17G then reads, as targets for the my standard calculation, the measurement index associated with the measurement date and time immediately preceding the current one (past) and the measurement type "my standard measurement," as well as a predetermined number of measurement indexes associated with the measurement type "my standard measurement" within a predetermined period going back from the current measurement date and time. The calculation unit 17G then calculates the average values of the first index, second index, and third index for the multiple measurement indexes associated with the multiple my standard measurements with different measurement dates and times read as targets for the my standard calculation. That is, the calculation unit 17G calculates the average value of the multiple first indexes read as targets for the my standard calculation with different measurement dates and times as the first standard index. The calculation unit 17G also calculates the average value of the multiple second indexes read as targets for the my standard calculation with different measurement dates and times as the second standard index. The calculation unit 17G also calculates the average value of the multiple third indexes read as targets for the my standard calculation with different measurement dates and times as the third standard index.
[0086] FIG. 6 is an explanatory diagram of an example of a standard index (my standard).
[0087] Assume that the calculation unit 17G excludes the most recent measurement date and time, "2024 / 10 / 6 / 6:30," from the index management DB 12A as a target for My Standard calculation, and reads the measurement indices corresponding to the past measurement dates and times, "2024 / 10 / 5 / 6:25," "2024 / 10 / 4 / 6:20," "2024 / 10 / 3 / 7:10," "2024 / 10 / 2 / 6:30," and "2024 / 10 / 1 / 7:00," associated with the measurement type "My Standard Measurement," as targets for My Standard calculation. In this case, the calculation unit 17G calculates the average values of the first, second, and third indices for each of the five measurement indices corresponding to the five My Standard measurements read. Through these calculation processes, the calculation unit 17G calculates the first, second, and third standard indices.
[0088] While the number of measurement indicators with different measurement dates and times to be used in calculating My Standard is described as "5" as an example, the number of measurement indicators to be used in calculating My Standard may be any value greater than or equal to "2" and may be either a fixed value or a variable value. If the number of measurement indicators to be used in calculating My Standard is a fixed value, the number of measurement indicators may be changeable as needed by the user operating the UI unit 15. The predetermined period to be used in calculating My Standard may also be changeable as needed by the user operating the UI unit 15.
[0089] Furthermore, the calculation unit 17G may perform the same processing as above on the measurement index associated with the latest measurement date and time and measurement type "my standard measurement" as the object of my standard calculation, without excluding it from the object of my standard calculation.
[0090] Returning to Figure 2, we continue the explanation.
[0091] Comparator 17H compares the measurement indices, including the first index, second index, and third index derived based on the latest pulse wave 30 measured this time, with my standard (standard indices) calculated by calculator 17G. Display controller 17A then identifies the user's physical condition information based on the comparison result by comparator 17H. Display controller 17A displays display screen 20 including the identified physical condition information on display device 15A.
[0092] Physical condition information is information relating to the user's physical condition. The physical condition information includes information representing at least one of the user's physical condition and recommended actions for improving the physical condition. The user's physical condition is information representing a state estimated from the amount of activity related to the user's autonomic nerves, such as a state in which concentration is likely to increase, a relaxed state, stable balance, etc. The recommended actions are information representing actions recommended for improving the user's physical condition. The recommended actions are information such as, for example, a change of mood to reduce stress, physical activity, etc.
[0093] The comparison unit 17H compares the measurement index with the personal standard based on the criteria information 12C. Furthermore, the display control unit 17A identifies the physical condition information corresponding to the comparison result based on the criteria information 12C.
[0094] FIG. 7 is a schematic diagram showing an example of the data configuration of the criteria information 12C.
[0095] The criteria information 12C is a database that associates the contents of comparison by the comparison unit 17H with identification information of the corresponding physical condition information. The data format of the criteria information 12C is not limited to a database.
[0096] Comparator 17H determines whether the first index based on the latest measurement result of pulse wave 30 is 95% or more of the first standard index. The latest measurement result of pulse wave 30 may be referred to as the latest measurement result.
[0097] If the comparison unit 17H determines that the first index based on the latest measurement result of the pulse wave 30 is 95% or more of the first standard index, it further determines whether the autonomic nervous balance of the latest measurement is +1 or more in favor of sympathetic nervous activity compared to the standard autonomic nervous balance.
[0098] The latest measured autonomic nervous balance is information that represents the ratio between the second index representing the amount of sympathetic nervous activity and the third index representing the amount of parasympathetic nervous activity, derived based on the most recently measured pulse wave 30.
[0099] The standard autonomic nervous balance is information that represents the ratio between the second standard index, which represents the standard value of sympathetic nervous activity, and the third standard index, which represents the standard value of parasympathetic nervous activity, included in My Standard (standard index).
[0100] If the display control unit 17A determines that the first index based on the latest measurement result is 95% or more of the first standard index and that the autonomic nervous balance of the latest measurement is +1 or more compared to the standard autonomic nervous balance, indicating that sympathetic nervous activity is dominant, it identifies the health information identified by the health information ID (identification) "A" associated with these conditions in the judgment criteria information 12C as the user's health information.
[0101] Furthermore, when the comparison unit 17H determines that the first index based on the latest measurement result is 95% or more of the first standard index, it further determines whether the autonomic nerve balance of the latest measurement is the same as the standard autonomic nerve balance.
[0102] If the display control unit 17A determines that the first index based on the latest measurement result is 95% or more of the first standard index and that the autonomic nervous balance of the latest measurement is identical to the standard autonomic nervous balance, it identifies the health information identified by the health information ID "E" associated with these conditions in the judgment criteria information 12C as the user's health information.
[0103] Furthermore, if the comparison unit 17H determines that the first index based on the latest measurement result is 95% or more of the first standard index, it further determines whether the autonomic nervous balance of the latest measurement is +1 or more in favor of parasympathetic nervous activity compared to the standard autonomic nervous balance.
[0104] If the display control unit 17A determines that the first index based on the latest measurement result is 95% or more of the first standard index and that the autonomic nervous balance of the latest measurement is +1 or more in favor of parasympathetic nervous activity compared to the standard autonomic nervous balance, the display control unit 17A identifies the health information identified by the health information ID "B" associated with these conditions in the judgment criteria information 12C as the user's health information.
[0105] On the other hand, if the comparison unit 17H determines that the first index based on the latest measurement result of the pulse wave 30 is less than 95% of the first standard index, it further determines whether the autonomic nervous balance of the latest measurement is +1 or more in favor of sympathetic nervous activity compared to the standard autonomic nervous balance.
[0106] If the display control unit 17A determines that the first index based on the latest measurement result is less than 95% of the first standard index and that the autonomic nervous balance of the latest measurement is +1 or more compared to the standard autonomic nervous balance, indicating that sympathetic nervous activity is dominant, it identifies the health information identified by the health information ID ``C'' associated with these conditions in the judgment criteria information 12C as the user's health information.
[0107] Furthermore, when the comparison unit 17H determines that the first index based on the latest measurement result is less than 95% of the first standard index, it further determines whether the autonomic nerve balance of the latest measurement is the same as the standard autonomic nerve balance.
[0108] If the display control unit 17A determines that the first index based on the latest measurement result is less than 95% of the first standard index and that the autonomic nervous balance of the latest measurement is identical to the standard autonomic nervous balance, it identifies the health information identified by the health information ID "F" associated with these conditions in the judgment criteria information 12C as the user's health information.
[0109] Furthermore, if the comparison unit 17H determines that the first index based on the latest measurement result is less than 95% of the first standard index, it further determines whether the autonomic nervous balance of the latest measurement is +1 or more in favor of parasympathetic nervous activity compared to the standard autonomic nervous balance.
[0110] If the display control unit 17A determines that the first index based on the latest measurement result is 95% or more of the first standard index and that the autonomic nervous balance of the latest measurement is +1 or more in favor of parasympathetic nervous activity compared to the standard autonomic nervous balance, the display control unit 17A identifies the health information identified by the health information ID "D" associated with these conditions in the judgment criteria information 12C as the user's health information.
[0111] The display control unit 17A identifies the physical condition information identified by the physical condition information ID from the physical condition information management DB 12D.
[0112] FIG. 8 is a schematic diagram showing an example of the data structure of the physical condition information management DB 12D.
[0113] The physical condition information management DB 12D is a database in which physical condition information IDs are associated with physical condition information. The data format of the physical condition information management DB 12D is not limited to a database.
[0114] The physical condition information management DB 12D stores physical condition information that indicates the user's physical condition according to the comparison result between the measurement index and the personal standard, in association with each physical condition information ID that corresponds to the comparison result.
[0115] The display control unit 17A reads the physical condition information identified by the physical condition information ID specified based on the comparison result between the measurement index and the personal standard from the physical condition information management DB 12D. Then, the display control unit 17A displays the read physical condition information on the display device 15A. In this embodiment, the display control unit 17A displays a measurement result screen including the physical condition information on the display device 15A.
[0116] The measurement result screen is a display screen 20 for information related to the measurement results of the user's pulse wave 30. The measurement result screen may include at least physical condition information. The measurement result screen may further include information related to the first index, the second index, and the third index derived based on the user's pulse wave 30. The information related to the first index, the second index, and the third index may further include at least one of the values of the first index, the second index, and the third index, information related to autonomic nerve balance expressed by the ratio between the second index and the third index, and relative evaluation information of the first index.
[0117] 9A to 9C are schematic diagrams showing an example of the measurement result screen 21. The measurement result screen 21 is an example of the display screen 20.
[0118] 9A is a schematic diagram of an example of a measurement result screen 21D when the display control unit 17A specifies the physical condition information identified by the physical condition information ID "C" as the physical condition information corresponding to the comparison result. The measurement result screen 21D is an example of the measurement result screen 21.
[0119] The measurement result screen 21D includes information 20D7 indicating the measurement date and time and type of measurement, information 20D1 regarding the total amount of autonomic nervous activity, information 20D3 indicating the autonomic nervous balance of the most recent measurement, physical condition information 20D4, information 20D5 indicating the heart rate, a next button image 20D6, and the like.
[0120] The information 20D1 relating to the total amount of autonomic nerve activity includes a first index 20D1c representing the total amount of autonomic nerve activity, relative evaluation information of the first index, and the like.
[0121] The relative evaluation information of the first index is information indicating the relative age of the total amount of autonomic nervous activity represented by the first index compared to a standard total amount of autonomic nervous activity for each age of a human. For example, the display control unit 17A calculates the relative evaluation information from the first index and displays information 20D1 including an image 20D1a indicating the position of the age represented by the relative evaluation information on a gauge image representing the human age, an age 20D1b represented by the relative evaluation information, a first index 20D1c, and a message 20D1d. The message 20D1d includes the first index and the relative evaluation information and is information representing a message to the user.
[0122] Information 20D3 representing the latest measured autonomic nervous balance includes a numerical value representing the ratio between the second index and the third index representing the autonomic nervous balance, and a gauge image visually representing the ratio between the second index and the third index representing the autonomic nervous balance.
[0123] The information 20D5 representing the heart rate may be a pulse rate derived by analyzing the measured pulse wave 30 using a known method.
[0124] 9B is a schematic diagram of an example of a measurement result screen 21E when the display control unit 17A specifies the physical condition information identified by the physical condition information ID "B" as the physical condition information corresponding to the comparison result. The measurement result screen 21E is an example of the measurement result screen 21.
[0125] The measurement result screen 21E includes information 20E7 indicating the measurement date and time and type of measurement, information 20E1 regarding the total amount of autonomic nervous activity, information 20E3 indicating the autonomic nervous balance of the most recent measurement, physical condition information 20E4, information 20E5 indicating the heart rate, a next button image 20E6, and the like.
[0126] The information 20E1 relating to the total amount of autonomic nerve activity includes a first index 20E1c representing the total amount of autonomic nerve activity, relative evaluation information of the first index, and the like.
[0127] The display control unit 17A also calculates relative evaluation information from the first index and displays information 20E1 including an image 20E1a representing the position of the age represented by the relative evaluation information on a gauge image representing human age, an age 20E1b represented by the relative evaluation information, the first index 20E1c, and a message 20E1d. The message 20E1d includes the first index and the relative evaluation information and is information representing a message to the user.
[0128] The information 20E3 representing the latest measured autonomic nervous balance includes a numerical value representing the ratio between the second index and the third index representing the autonomic nervous balance, and a gauge image visually representing the ratio.
[0129] The information 20E5 representing the heart rate may be a pulse rate derived by analyzing the measured pulse wave 30 using a known method.
[0130] 9C is a schematic diagram of an example of the measurement result screen 21 F. The measurement result screen 21 F is an example of the measurement result screen 21.
[0131] The measurement result screen 21F includes information 20F7 indicating the measurement date and time and type of measurement, information 20F1 regarding the total amount of autonomic nervous activity, information 20F3 indicating the autonomic nervous balance of the most recent measurement, information 20F5 indicating the heart rate, a next button image 20F6, and the like.
[0132] The information 20F1 relating to the total amount of autonomic nerve activity includes a first index 20F1c representing the total amount of autonomic nerve activity, relative evaluation information of the first index, and the like.
[0133] The display control unit 17A also calculates relative evaluation information from the first index and displays information 20F1 including an image 20F1a indicating the position of the age indicated by the relative evaluation information on a gauge image representing human age, an age 20F1b indicated by the relative evaluation information, the first index 20F1c, and a message 20F1d. The message 20F1d includes the first index and the relative evaluation information and is information representing a message to the user.
[0134] The information 20F3 representing the latest measured autonomic nervous balance includes a numerical value representing the ratio between the second index and the third index representing the autonomic nervous balance, and a gauge image visually representing the ratio.
[0135] The information 20F5 representing the heart rate may be a pulse rate derived by analyzing the measured pulse wave 30 using a known method.
[0136] In this way, display control unit 17A displays on display device 15A a measurement result screen 21 including the physical condition information identified by the physical condition information ID specified according to the comparison result by comparison unit 17H. Furthermore, measurement result screen 21 may include information regarding the first index, the second index, and the third index derived based on the user's pulse wave 30. The information regarding the first index, the second index, and the third index may include at least one of the values of each of the first index, the second index, and the third index, information regarding autonomic nerve balance expressed by the ratio between the second index and the third index, and relative evaluation information of the first index.
[0137] Therefore, the user can easily check his / her own first index, second index, and third index, as well as the comparison results of these measurement indexes with the standard index (my standard), by visually checking the measurement result screen 21. Furthermore, by using the standard index (my standard), which is an index that reduces the variation in the measurement environment of the pulse wave 30, as a comparison target for the measurement index, the display control unit 17A can effectively provide the user with the degree of variation of the information related to the currently measured pulse wave 30 relative to the standard index.
[0138] Furthermore, the user can check their own measurement indices by viewing the measurement result screen 21. Furthermore, the user can easily check the user's physical condition, recommended behavior, and the like, represented by the physical condition information, by checking the physical condition information included in the measurement result screen 21. Furthermore, the display control unit 17A displays the measurement result screen 21, which includes physical condition information based on the first index, second index, and third index, on the display device 15A. By using these three measurement indices (first index, second index, and third index), the display control unit 17A can provide highly accurate physical condition information of the user. Furthermore, the display control unit 17A can provide information regarding the user's physical condition and improvement of the physical condition.
[0139] Next, an example of the flow of information processing executed by the information processing device 10 of this embodiment will be described.
[0140] 10 is a flowchart showing an example of the flow of information processing executed by information processing device 10 of this embodiment. When an information processing program for measuring user pulse wave 30 is started by accepting an operation instruction or the like from UI unit 15 by a user, processing unit 17 of information processing device 10 executes the flowchart shown in FIG.
[0141] The display control unit 17A displays an initial screen on the display device 15A (step S100). For example, the display control unit 17A displays the display screen 20A shown in FIG. 3A on the display device 15A. The display screen 20A includes a My Standard Measurement selection button 20A1 and a Spot Measurement selection button 20A2 for accepting the selection of the type of measurement. Note that the display control unit 17A may display the measurement result screen 21 that was displayed during the previous measurement of the pulse wave 30 at startup. Then, after displaying the measurement result screen 21, the display screen 20A may be displayed.
[0142] When the user selects the My Standard Measurement selection button 20A1 or the Spot Measurement selection button 20A2 included in the display screen 20A by operating the UI unit 15, the reception unit 17B receives measurement type information indicating the type of measurement, either My Standard Measurement or Spot Measurement, that has been selected (step S102).
[0143] Next, display control unit 17A displays a measurement-in-progress screen on display device 15A, indicating that measurement is in progress, and pulse wave acquisition unit 17C transmits a pulse wave measurement start instruction signal to pulse wave sensor 16 (step S104). As a result of the processing of step S104, display screen 20B shown in FIG. 3B is displayed on display device 15A. Furthermore, as a result of the processing of step S104, measurement of pulse wave 30 by pulse wave sensor 16 begins. At the start of measurement, pulse wave sensor 16 begins irradiating the user's measurement target area with IR light from IR-LED 16A1, and outputs to processing unit 17 a pulse wave signal of pulse wave 30, which is represented by a transition in output value corresponding to the amount of IR light received by light-receiving unit 16B and reflected by the measurement target area within a predetermined time period from the start of measurement.
[0144] The pulse wave acquirer 17C receives the pulse wave signal of the pulse wave 30 from the pulse wave sensor 16 (step S106).
[0145] Next, display control unit 17A displays display screen 20C for accepting input of tag information on display device 15A (step S108). By the processing of step S108, for example, display screen 20C shown in Fig. 3C is displayed on display device 15A. The user operates UI unit 15 while viewing display screen 20C to select or input tag information.
[0146] The accepting unit 17B accepts the tag information input by the user via the display screen 20C (step S110).
[0147] Deriving unit 17D derives measurement indices including a first index, a second index, and a third index based on frequency spectrum 32 of pulse wave 30 represented by the pulse wave signal acquired in step S106 (step S112).
[0148] The memory control unit 17E associates the measurement date and time of the pulse wave 30 represented by the pulse wave signal acquired in step S106, the type of measurement accepted in step S102, the measurement index derived in step S112, and the tag information accepted in step S110, and registers them in the index management DB 12A (step S114).
[0149] Next, the judgment unit 17F judges whether or not the my standard measurement M has been performed multiple times (step S116). For example, the judgment unit 17F makes the judgment in step S116 by determining whether or not the number of measurement indices registered in association with the measurement type "my standard measurement" in the index management DB 12A is two or more. If it is determined in step S116 that the my standard measurement M has not been performed multiple times (step S116: No), the process proceeds to step S118.
[0150] In step S118, the display device 15A displays a measurement result screen that does not include the user's physical condition information on the display device 15A (step S118), and then ends this routine.
[0151] On the other hand, if it is determined that the my-standard measurement has been performed multiple times (step S116: Yes), the process proceeds to step S120.
[0152] In step S120, the calculation unit 17G calculates a standard index (my standard) (step S120).
[0153] Next, comparison unit 17H determines whether the first index based on pulse wave 30 of the latest measurement result is 95% or more of the first standard index (step S122). Pulse wave 30 of the latest measurement result is pulse wave 30 represented by the pulse wave signal acquired in step S106.
[0154] If it is determined that the first index based on the pulse wave 30 of the latest measurement result is 95% or more of the first standard index (step S122: Yes), the process proceeds to step S124.
[0155] In step S124, the comparison unit 17H determines whether the autonomic nerve balance of the latest measurement is +1 or more relative to the standard autonomic nerve balance, indicating that sympathetic nerve activity is dominant (step S124). The autonomic nerve balance of the latest measurement represents the ratio of the second index representing the amount of sympathetic nerve activity to the third index representing the amount of parasympathetic nerve activity, which were derived in step S112 based on the pulse wave 30 represented by the pulse wave signal acquired in step S106. The standard autonomic nerve balance represents the ratio of the second standard index representing the standard value of the amount of sympathetic nerve activity to the third standard index representing the standard value of the amount of parasympathetic nerve activity, both of which are included in the my standard calculated in step S120.
[0156] If the comparison unit 17H determines that the autonomic nervous balance of the latest measurement is higher in sympathetic nervous activity by +1 or more than the standard autonomic nervous balance (step S124: Yes), the process proceeds to step S126. In step S126, the display control unit 17A displays on the display device 15A the measurement result screen 21 including the physical condition information identified by the physical condition information ID "A" associated with these conditions in the judgment criteria information 12C (step S126). Then, this routine ends.
[0157] If the comparison unit 17H makes a negative determination in step S124 (step S124: No), the comparison unit 17H proceeds to step S128. In step S128, the comparison unit 17H determines whether the latest measured autonomic nerve balance is the same as the standard autonomic nerve balance (step S128). If the comparison unit 17H determines that the latest measured autonomic nerve balance is the same as the standard autonomic nerve balance (step S128: Yes), the comparison unit 17H proceeds to step S130.
[0158] In step S130, the display control unit 17A displays the measurement result screen 21 including the physical condition information identified by the physical condition information ID "E" associated with these conditions in the judgment criteria information 12C on the display device 15A (step S130), and then ends this routine.
[0159] If the comparison unit 17H makes a negative determination in step S128 (step S128: No), the process proceeds to step S132. A negative determination in step S128 occurs when the autonomic nervous balance of the latest measurement is determined to be +1 or more relative to the standard autonomic nervous balance, indicating that parasympathetic nervous activity is dominant. In step S132, the display control unit 17A displays the measurement result screen 21 on the display device 15A, which includes the physical condition information identified by the physical condition information ID "B" associated with these conditions in the determination criteria information 12C (step S132). Then, this routine ends.
[0160] On the other hand, if the comparison unit 17H determines that the first index based on the pulse wave 30 of the latest measurement result is less than 95% of the first standard index (step S122: No), the process proceeds to step S134.
[0161] In step S134, the comparison unit 17H determines whether the autonomic nerve balance of the latest measurement is +1 or more relative to the standard autonomic nerve balance, indicating that the sympathetic nerve activity is dominant (step S134).
[0162] If the comparison unit 17H determines that the autonomic nervous balance of the latest measurement is +1 or more relative to the standard autonomic nervous balance, indicating that sympathetic nervous activity is dominant (step S134: Yes), the process proceeds to step S136. In step S136, the display control unit 17A displays on the display device 15A the measurement result screen 21 including the physical condition information identified by the physical condition information ID "C" associated with these conditions in the judgment criteria information 12C (step S136). Then, this routine ends.
[0163] If the comparison unit 17H makes a negative determination in step S134 (step S134: No), the process proceeds to step S138. In step S138, the comparison unit 17H determines whether the latest measured autonomic nerve balance is the same as the standard autonomic nerve balance (step S138). If the comparison unit 17H determines that the latest measured autonomic nerve balance is the same as the standard autonomic nerve balance (step S138: Yes), the process proceeds to step S140.
[0164] In step S140, the display control unit 17A displays the measurement result screen 21 including the physical condition information identified by the physical condition information ID "F" associated with these conditions in the judgment criteria information 12C on the display device 15A (step S140), and then ends this routine.
[0165] If the comparison unit 17H makes a negative determination in step S138 (step S138: No), the process proceeds to step S142. A negative determination in step S138 occurs when the autonomic nervous balance of the latest measurement is determined to be +1 or more relative to the standard autonomic nervous balance, indicating that parasympathetic nervous activity is dominant. In step S142, the display control unit 17A displays the measurement result screen 21 on the display device 15A, which includes the physical condition information identified by the physical condition information ID "D" associated with these conditions in the determination criteria information 12C (step S142). Then, this routine ends.
[0166] As described above, in the information processing device 10 of this embodiment, the processing unit 17 displays on the display device 15A physical condition information related to the user's physical condition based on the first index, the second index, and the third index. The first index is an index representing the total amount of autonomic nerve activity derived based on the integral value of the intensities of all frequency band components included in the frequency spectrum 32 of the user's pulse wave 30. The second index is an index representing the amount of sympathetic nerve activity derived based on the integral value of the intensities of low-frequency band components below a first frequency F1 included in the frequency spectrum 32. The third index is an index representing the amount of parasympathetic nerve activity derived based on the integral value of the intensities of high-frequency band components equal to or greater than a second frequency F2 included in the frequency spectrum 32.
[0167] In this way, processing unit 17 of information processing device 10 of this embodiment derives the first index, second index, and third index based on frequency spectrum 32 of user's pulse wave 30. Processing unit 17 then displays user's physical condition information based on these first index, second index, and third index on display device 15A. That is, processing unit 17 of this embodiment derives and displays user's physical condition information by using the first index, second index, and third index related to pulse wave 30.
[0168] Therefore, the information processing device 10 of this embodiment can provide highly accurate physical condition information of the user.
[0169] As described above, the information processing device 10 of this embodiment displays physical condition information based on the comparison result between the user's personal standard (standard index) and the measurement indexes (first index, second index, third index). The physical condition information may include information indicating at least one of the user's physical condition and recommended actions (advice) for improving the physical condition.
[0170] Therefore, in addition to the above-mentioned effects, the information processing device 10 of this embodiment can provide highly accurate physical condition information and physical condition improvement information of the user.
[0171] (Hardware configuration) FIG. 11 is a hardware configuration diagram showing an example of a computer 1000 that realizes the functions of the information processing device 10 according to the above embodiment.
[0172] The computer 1000 includes a CPU 1100, a RAM 1200, a ROM (Read Only Memory) 1300, a HDD (Hard Disk Drive) 1400, a communication interface 1500, and an input / output interface 1600. The components of the computer 1000 are connected by a bus 1050.
[0173] The CPU 1100 operates and controls each unit based on programs stored in the ROM 1300 or the HDD 1400. For example, the CPU 1100 loads the programs stored in the ROM 1300 or the HDD 1400 into the RAM 1200 and executes processing corresponding to the various programs.
[0174] The ROM 1300 stores boot programs such as a Basic Input Output System (BIOS) executed by the CPU 1100 when the computer 1000 is started, and programs that depend on the hardware of the computer 1000 .
[0175] HDD 1400 is a computer-readable recording medium that non-temporarily records programs executed by CPU 1100 and data used by such programs. Specifically, HDD 1400 is a recording medium that records a program according to the present disclosure, which is an example of program data 1450.
[0176] The communication interface 1500 is an interface for connecting the computer 1000 to an external network 1550 (e.g., the Internet). For example, the CPU 1100 receives data from other devices and transmits data generated by the CPU 1100 to other devices via the communication interface 1500.
[0177] The input / output interface 1600 is an interface for connecting the input / output device 1650 and the computer 1000. The input / output device 1650 is the above-mentioned UI unit 15 or the like.
[0178] For example, the CPU 1100 receives data from the input unit 18, such as a keyboard or a mouse, via the input / output interface 1600. The CPU 1100 also transmits data to the UI unit 15 via the input / output interface 1600. The input / output interface 1600 may also function as a media interface that reads programs and the like recorded on a predetermined recording medium. Examples of media include optical recording media such as DVDs (Digital Versatile Discs) and PDs (Phase Change Rewritable Discs), magneto-optical recording media such as MOs (Magneto-Optical Discs), tape media, magnetic recording media, and semiconductor memories.
[0179] For example, when the computer 1000 functions as the information processing device 10 according to the embodiment, the CPU 1100 of the computer 1000 executes an information processing program loaded onto the RAM 1200 to implement functions of a display control unit 17A, a reception unit 17B, a pulse wave acquisition unit 17C, a derivation unit 17D, a memory control unit 17E, a determination unit 17F, a calculation unit 17G, a comparison unit 17H, and the like. The HDD 1400 stores program data 1450, which is the information processing program according to the present disclosure, and data in the memory unit 12. The CPU 1100 reads and executes the program data 1450 from the HDD 1400. Alternatively, the CPU 1100 may acquire these programs from another device via an external network 1550.
