Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional method, even for a user with a low interoceptive sensation, if a value is input based on the knowledge that the heart rate is about once per second, there is a case where the user may be erroneously determined to have a high interoceptive sensation. For this reason, a technique that can measure the interoceptive sensation of a user with high accuracy has been desired.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms.

[0006] According to one embodiment of the present disclosure, an interoceptive sensation measuring device (100) is provided. This interoceptive sensation measuring device comprises: an actual heart rate acquisition unit (21) that acquires the actual heart rate timing (AHT) of the actual heart rate (AH) of the user (SB); a subjective heart rate acquisition unit (22) that acquires the subjective heart rate timing (SHT) of the subjective heart rate (SH) of the user (SB); and an interoceptive sensation analysis unit (23) that analyzes the user's interoceptive sensation based on the actual heart rate timing and the subjective heart rate timing.

[0007] In this type of interoceptive sensation measurement device, the interoceptive sensation analysis unit analyzes the user's interoceptive sensation based on the actual heart rate timing acquired by the actual heart rate acquisition unit and the subjective heart rate timing acquired by the subjective heart rate acquisition unit. Therefore, it is not necessary to input a numerical heart rate value for this analysis. As a result, the user's interoceptive sensation can be measured with high accuracy. [Brief explanation of the drawing]

[Figure 8] This figure schematically shows a display unit that shows a virtual heart rate in the third embodiment. [Modes for carrying out the invention]

[0009] A. First Embodiment: The interoceptive sensation measuring device 100 measures the interoceptive sensation of the user SB. Generally, interoceptive sensation refers to the sensation of a person's physiological state, such as body temperature, heart rate, and the movement of internal organs, but in this disclosure, interoceptive sensation refers to a person's sensation of their own heart rate. "High interoceptive sensation" means that the person has a keen sense of their own heart rate, and conversely, "high interoceptive sensation" "Low" means having a dull sense of your own heart rate.

[0010] Interoceptive sensation is measured considering the "sensitivity" and "delay" of interoceptive sensation, as will be described later. The "sensitivity" and "delay" of interoceptive sensation are calculated based on the actual heart rate (AHT) of the user's actual heart rate (AH) and the subjective heart rate (SHT) of the user's subjective heart rate (SH), as will be described later. Note that "heart rate timing" refers to the timing when the heart beats.

[0011] As shown in Figure 1, the interoceptive sensation measurement device 100 comprises a display unit 10, a real heart rate acquisition unit 21, a subjective heart rate acquisition unit 22, a processor 23p, and a memory 30. The display unit 10 displays various menu screens for starting or stopping the measurement of the user's interoceptive sensation. The display unit 10 is composed of a liquid crystal display with touch panel functionality and has the function of accepting input by touch operation from the user's SB. The user's SB responds with subjective heart rate timing (SHT) by touch operation via the display unit 10.

[0012] The actual heart rate acquisition unit 21 acquires the actual heart rate timing (AHT) of the actual heart rate (AH). The actual heart rate acquisition unit 21 is, for example, composed of an electrocardiograph, and acquires the actual heart rate timing (AHT) based on the electrocardiogram recorded by the electrocardiograph.

[0013] The subjective heart rate acquisition unit 22 acquires the subjective heart rate SH and subjective heart rate timing SHT. The subjective heart rate acquisition unit 22 is composed of, for example, a pressure sensor provided on the display unit 10. The pressure sensor senses the pressure from the user SB's finger and acquires the subjective heart rate timing SHT that the user SB has answered.

[0014] The processor 23p functions as an interoceptive sensation analysis unit 23 by executing a program pre-stored in memory 30. The interoceptive sensation analysis unit 23 analyzes the user SB's interoceptive sensation based on actual heart rate timing (AHT) and subjective heart rate timing (SHT). The interoceptive sensation analysis unit 23 is composed of a dedicated computing device for analyzing interoceptive sensation. The interoceptive sensation analysis unit 23 can receive data acquired by the actual heart rate acquisition unit 21 and the subjective heart rate acquisition unit 22 using a wireless LAN (Local Area Network) communication means such as Wi-Fi or Bluetooth®. The communication means may also be a wired LAN.

[0015] Next, the procedure for measuring the interoceptive sensation of the user SB will be described using Figures 2 and 3. The display unit 10 displays the virtual heart rate VH. As shown in Figure 2, the virtual heart rate VH is represented by the pulsation of a heart-shaped icon that indicates a virtual heart. That is, the heart-shaped icon pulsates at the virtual heart rate timing VHT, which is the virtual heart rate timing. As shown in the upper part of Figure 2, the virtual heart rate VH pulsates periodically, changing from diastolic Di (shown by a solid line) through systolic Sy (shown by a dashed line) and back to diastolic Di. Note that when the virtual heart rate VH pulsates, no sound associated with the pulsation of the virtual heart rate VH is generated. This prevents the sound associated with the pulsation of the virtual heart rate VH from interfering with the user SB's subjective heart rate timing SHT response.

[0016] The virtual heart beat VH is linked to the touch operation. In the lower part of FIG. 2, a heart beat phase adjustment unit PA for adjusting the heart beat phase and a heart beat cycle adjustment unit CA for adjusting the heart beat cycle are shown. Here, the "heart beat phase" and the "heart beat cycle" are parameters characterizing the heart beat timing. The "heart beat phase" refers to the time when the heart beat reaches the diastolic phase Di, and the "heart beat cycle" refers to the time it takes for the heart beat to reach the next diastolic phase Di from the diastolic phase Di. By performing a touch operation so that the user SB turns the heart beat phase adjustment unit PA counterclockwise, the virtual heart beat phase VHP, which is the heart beat phase of the virtual heart beat VH, can be adjusted to be delayed. By performing a touch operation so that the heart beat phase adjustment unit PA is turned clockwise, the virtual heart beat phase VHP can be adjusted to be advanced. Similarly, by performing a touch operation so that the user SB turns the heart beat cycle adjustment unit CA counterclockwise, the virtual heart beat cycle VHC, which is the heart beat cycle of the virtual heart beat VH, can be adjusted to become shorter. By performing a touch operation so that the heart beat cycle adjustment unit CA is turned clockwise, the virtual heart beat cycle VHC can be adjusted to become longer. By the above-described operation, the user SB adjusts the virtual heart beat timing VHT so that the virtual heart beat phase VHP and the virtual heart beat cycle VHC in the virtual heart beat VH are synchronized with the actual heart beat timing AHT, and answers the subjective heart beat timing SHT.

[0017] In the upper part of FIG. 3, the virtual heart beat timing VHT of the virtual heart beat VH first presented, and the virtual heart beat phase VHP and the virtual heart beat cycle VHC at the virtual heart beat timing VHT are shown. In the middle part of FIG. 3, the subjective heart beat timing SHT answered by the user SB, and the subjective heart beat phase SHP which is the heart beat phase at the subjective heart beat timing SHT and the subjective heart beat cycle SHC which is the heart beat cycle at the subjective heart beat timing SHT are shown. In the lower part of FIG. 3, the actual heart beat timing AHT of the actual heart beat AH, and the actual heart beat phase AHP which is the heart beat phase at the actual heart beat timing AHT, and the actual heart beat cycle AHC which is the heart beat cycle at the actual heart beat timing AHT are shown.

[0018] As shown in the upper part of FIG. 3, the initially presented virtual heartbeat timing VHT has a virtual heartbeat phase VHP set to be later than the actual heartbeat phase AHP, and a virtual heartbeat cycle VHC set to be longer than the actual heartbeat cycle AHC. Therefore, the user SB can speed up the virtual heartbeat phase VHP by performing a touch operation to turn the heartbeat phase adjustment unit PA shown in FIG. 2 clockwise, and adjust the virtual heartbeat timing VHT so that the virtual heartbeat phase VHP is synchronized with the actual heartbeat phase AHP. Also, the user SB can shorten the virtual heartbeat cycle VHC by performing a touch operation to turn the heartbeat cycle adjustment unit CA shown in FIG. 2 counterclockwise, and adjust the virtual heartbeat timing VHT so that the virtual heartbeat cycle VHC is synchronized with the actual heartbeat cycle AHC.

[0019] By the above-described operation, the user SB answers the virtual heartbeat timing VHT closer to the actual heartbeat timing AHT than the initially presented virtual heartbeat timing VHT as the subjective heartbeat timing SHT. The subjective heartbeat acquisition unit 22 acquires the subjective heartbeat timing SHT answered by the user SB.

[0020] Note that a user SB with a low interoceptive sensation may erroneously determine that the subjective heartbeat cycle SHC is a value less than or equal to 1 / 2 or greater than or equal to 2 times the actual heartbeat cycle AHC. To prevent this, the initially presented virtual heartbeat VH is set to be presented randomly within a range where the virtual heartbeat cycle VHC is between 1 / 2 and 2 times the actual heartbeat cycle AHC.

[0021] As shown in FIG. 3, a deviation Gp occurs between the subjective heartbeat phase SHP and the actual heartbeat phase AHP. As will be described later, the deviation Gp is used by the interoceptive sensation analysis unit 23 to analyze the "delay" of the interoceptive sensation. Hereinafter, a method for calculating the "sensitivity" and "delay" of the interoceptive sensation from the subjective heartbeat timing SHT and the actual heartbeat timing AHT obtained by the above-described procedure will be described using FIGS. 4 and 5.

[0022] Figure 4 shows the distribution of the difference Gp between actual heart rate phase AHP and subjective heart rate phase SHP obtained during a predetermined measurement time (hereinafter referred to as the "predetermined measurement time"). The distribution of the difference Gp follows a normal distribution as an example. The Sgp value shown in Figure 4 corresponds to the average value of the difference Gp between subjective heart rate phase SHP and actual heart rate phase AHP obtained during the predetermined measurement time.

[0023] Figure 5 shows the distribution of actual heart rate cycles (AHC) and subjective heart rate cycles (SHC) obtained during a predetermined measurement time. The distributions of actual heart rate cycles (AHC) and subjective heart rate cycles (SHC) follow a normal distribution, as an example. The Sac value shown in Figure 5 corresponds to the average value of actual heart rate cycles (AHC) obtained during the predetermined measurement time, and the Svc value shown in Figure 5 corresponds to the average value of subjective heart rate cycles (SHC) obtained during the predetermined measurement time.

[0024] In this disclosure, the "sensitivity" and "delay" of interoceptive sensation are defined by the following equations (1) and (2). (Interoceptive sensitivity) = 1 - {|(1 / Sac) - (1 / Svc)| / (1 / Sac)} ·· (1) (Interoceptive "delay") = Sgp···(2) The closer the value calculated in equation (1) is to "1", the more accurately the user SB was able to report their own heart rate during the predetermined measurement time. Similarly, the closer the value calculated in equation (2) is to "0", the smaller the user SB was able to report the deviation Gp value during the predetermined measurement time. The interoceptive sensation analysis unit 23 uses the values ​​calculated in equations (1) and (2) above to analyze the user SB's interoceptive sensation. By analyzing the user SB's interoceptive sensation using the procedure described above, the "sensitivity" and "delay" in interoceptive sensation can be calculated with high accuracy, and the user SB's interoceptive sensation can be measured with high accuracy.

[0025] In the first embodiment, the interoceptive sensation measuring device 100 measured the user SB's interoceptive sensation based solely on equations (1) and (2) above, but the parameters used to measure interoceptive sensation are not limited to these. For example, the value of Sgp_peak shown in Figure 4 corresponds to the peak value in the distribution of deviation Gp obtained during a predetermined measurement time. Also, the value of Sgpσ shown in Figure 4 corresponds to the standard deviation value in the distribution of deviation Gp obtained during a predetermined measurement time. Furthermore, the value of Sac_peak shown in Figure 5 corresponds to the peak value in the distribution of actual heart rate cycle AHC obtained during a predetermined measurement time, and the value of Svc_peak corresponds to the peak value in the distribution of subjective heart rate cycle SHC obtained during a predetermined measurement time. Furthermore, the value of Sacσ shown in Figure 5 corresponds to the standard deviation value in the distribution of actual heart rate cycle AHC obtained during a predetermined measurement time, and the value of Svcσ corresponds to the standard deviation value in the distribution of subjective heart rate cycle SHC obtained during a predetermined measurement time.

[0026] The values ​​expressed by equations (3) and (4) below are parameters that correlate with the "sensitivity" of interoceptive sensation. Svc_peak / Sac_peak···(3) Sgp_peak···(4) Furthermore, the values ​​expressed by equations (5) and (6) below are parameters that correlate with the measurement accuracy of interoceptive sensation. Svcσ / Sacσ ···(5) Sgpσ···(6) In addition to equations (1) and (2), the interoceptive sensation analysis unit 23 can also analyze the user SB's interoceptive sensation using equations (3) to (6).

[0027] According to the interoceptive sensation measuring device 100 described above, the interoceptive sensation analysis unit 23 analyzes the user's interoceptive sensation based on the actual heart rate timing (AHT) acquired by the actual heart rate acquisition unit 21 and the subjective heart rate timing (SHT) acquired by the subjective heart rate acquisition unit 22. Therefore, it is not necessary to input a numerical value for heart rate in this analysis. As a result, the user's interoceptive sensation can be measured with high accuracy.

[0028] Furthermore, since the interoceptive sensory measurement device 100 is equipped with a touch-operable display unit 10, the user SB can intuitively and familiarly answer subjective heart rate timing (SHT) questions using touch operations. This improves the accuracy of the user SB's subjective heart rate timing (SHT) answers.

[0029] Furthermore, since the display unit 10 displays the virtual heart rate VH in conjunction with touch operation, the user SB can accurately adjust the virtual heart rate phase VHP and virtual heart rate cycle VHC by utilizing the virtual heart rate VH visually presented via the display unit 10.

[0030] Furthermore, the display unit 10 displays the virtual heart rate VH, which is set to a range of 1 / 2 or more and 2 times or less of the actual heart rate AHC in the actual heart rate timing AHT. This prevents the user SB from mistakenly determining that the subjective heart rate SHC is less than or equal to 1 / 2 or more than 2 times the actual heart rate AHC. As a result, the user SB's interoceptive sensation can be measured with higher accuracy.

[0031] B. Second Embodiment: Next, the procedure for measuring the interoceptive sensation of the user SB in the second embodiment will be described using Figures 6 and 7. The interoceptive sensation measuring device 100 in the second embodiment differs from the first embodiment in that it displays the virtual heart rate VH in two parts: the first virtual heart rate VH1 and the second virtual heart rate VH2. Also, the subjective heart rate acquisition unit 22 in the second embodiment differs from the first embodiment in that it acquires the first subjective heart rate timing SHT1 corresponding to the first virtual heart rate VH1 and the second subjective heart rate timing SHT2 corresponding to the second virtual heart rate VH2. Components identical to those in the first embodiment are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0032] First, as shown on the left side of Figure 6, the display unit 10 displays the first virtual heartbeat VH1 as the virtual heartbeat VH, which beats with a virtual heartbeat timing VHT. The first virtual heartbeat VH1 is set so that its virtual heartbeat phase VHP is different from the actual heartbeat timing AHT, while its virtual heartbeat cycle VHC is the same as the actual heartbeat timing AHT. The lower left side of Figure 6 shows the heartbeat phase adjustment unit PA. The user SB can adjust the virtual heartbeat phase VHP of the first virtual heartbeat VH1 by touching the heartbeat phase adjustment unit PA in a counterclockwise direction, and adjust the virtual heartbeat phase VHP of the first virtual heartbeat VH1 by touching the heartbeat phase adjustment unit PA in a clockwise direction. During this adjustment, the virtual heartbeat cycle VHC remains constant. As described later, the user SB responds to the first subjective heart rate timing SHT1 by adjusting the virtual heart rate timing VHT so that the virtual heart rate phase VHP in the first virtual heart rate VH1 is synchronized with the actual heart rate timing AHT.

[0033] Next, as shown on the right side of Figure 6, the display unit 10 displays the second virtual heartbeat VH2 as the virtual heartbeat VH, which beats with a virtual heartbeat timing VHT. The virtual heartbeat cycle VHC of the second virtual heartbeat VH2 is different from the actual heartbeat timing AHT, while the virtual heartbeat phase VHP is set based on the subjective heartbeat phase SHP in the first subjective heartbeat timing SHT1. The lower right side of Figure 6 shows the heartbeat cycle adjustment unit CA. The user SB can adjust the virtual heartbeat cycle VHC of the second virtual heartbeat VH2 to be shorter by touching the heartbeat cycle adjustment unit CA in a counterclockwise direction, and adjust the virtual heartbeat cycle VHC of the second virtual heartbeat VH2 to be longer by touching the heartbeat cycle adjustment unit CA in a clockwise direction. During this adjustment, the virtual heartbeat phase VHP remains constant. As described later, the user SB responds to the second subjective heart rate timing SHT2 by adjusting the virtual heart rate timing VHT so that the virtual heart rate cycle VHC in the second virtual heart rate VH2 is synchronized with the actual heart rate timing AHT.

[0034] The first row of Figure 7 shows the virtual heart rate timing (VHT) and virtual heart rate phase (VHP) for the first virtual heart rate (VH1) presented. The second row of Figure 7 shows the first subjective heart rate timing (SHT1) and subjective heart rate phase (SHP) for the first subjective heart rate timing (SHT1) as reported by the user SB.

[0035] The virtual heart rate timing VHT shown in the first row of Figure 7 is set so that the virtual heart rate phase VHP is set later than the actual heart rate phase AHP, while the virtual heart rate cycle VHC is set to be the same as the actual heart rate cycle AHC. Therefore, the user SB first advances the virtual heart rate phase VHP by touching the heart rate phase adjustment unit PA shown in the lower left of Figure 6 in a clockwise direction, and adjusts the virtual heart rate timing VHT so that the virtual heart rate phase VHP in the first virtual heart rate VH1 is synchronized with the actual heart rate phase AHP. As a result, the user SB responds with a virtual heart rate timing VHT that is closer to the actual heart rate timing AHT than the initially presented virtual heart rate timing VHT as the first subjective heart rate timing SHT1. The subjective heart rate acquisition unit 22 acquires the first subjective heart rate timing SHT1 that the user SB has responded with.

[0036] The third row of Figure 7 shows the virtual heart rate timing (VHT) and virtual heart rate cycle (VHC) for the second virtual heart rate (VH2). The second virtual heart rate (VH2) is set so that the virtual heart rate phase (VHP) is the same as the virtual heart rate phase (VHP) obtained for the first subjective heart rate timing (SHT1), while the virtual heart rate cycle (VHC) is set to be longer than the actual heart rate cycle (AHC). Here, "the same" means substantially the same, and it is considered the same even if the virtual heart rate phase (VHP) of the second virtual heart rate (VH2) is set within a range of ±10% of the actual heart rate cycle (AHC). The fourth row of Figure 7 shows the second subjective heart rate timing (SHT2) and the subjective heart rate cycle (SHC) for the second subjective heart rate timing (SHT2) as reported by the user (SB).

[0037] Next, the user SB shortens the virtual heart rate cycle VHC by touching the heart rate cycle adjustment unit CA shown in the lower right of Figure 6 in a counterclockwise direction, and adjusts the virtual heart rate timing VHT so that the virtual heart rate cycle VHC in the second virtual heart rate VH2 is synchronized with the actual heart rate cycle AHC. As a result, the user SB responds with a virtual heart rate timing VHT that is closer to the actual heart rate timing AHT than the presented virtual heart rate timing VHT as the second subjective heart rate timing SHT2. The subjective heart rate acquisition unit 22 acquires the virtual heart rate timing VHT responded with by the user SB as the second subjective heart rate timing SHT2. The interoceptive sensation analysis unit 23 analyzes the user SB's interoceptive sensation based on the actual heart rate timing AHT and the second subjective heart rate timing SHT2.

[0038] The interoceptive sensation measuring device 100 described above produces the same effects as the first embodiment. Furthermore, since the user SB responds to the subjective heart rate timing SHT in two parts, the first subjective heart rate timing SHT1 and the second subjective heart rate timing SHT2, it is easier to perceive that the first subjective heart rate timing SHT1 and the second subjective heart rate timing SHT2 coincide with the actual heart rate timing AHT, compared to the case where the virtual heart rate phase VHP and virtual heart rate cycle VHC are synchronized with the actual heart rate timing AHT in a single operation and the subjective heart rate timing SHT is responded to. For this reason, the burden on the user SB when measuring interoceptive sensation can be reduced.

[0039] Furthermore, the user SB can first provide the first subjective heart rate timing (SHT1) for the subjective heart rate phase (SHP), which is the user SB's subjective perception of the heart rate phase, and then provide the second subjective heart rate timing (SHT2) for the subjective heart rate cycle (SHC), which is the user SB's subjective perception of the heart rate cycle. Since the subjective heart rate phase (SHP) differs depending on the part of the body where the user SB senses the heartbeat, it is thought that the discrepancy Gp between the subjective heart rate phase (SHP) and the actual heart rate timing (AHT) is likely to be larger than that of the subjective heart rate cycle (SHC). Because the user SB first provides the first subjective heart rate timing (SHT1) for the subjective heart rate phase (SHP), which is thought to have a larger discrepancy Gp from the actual heart rate timing (AHT), the accuracy of the response to the second subjective heart rate timing (SHT2) for the subjective heart rate cycle (SHC) is improved. As a result, the user SB's interoceptive sensation can be measured with higher accuracy.

[0040] C. Third Embodiment: The interoceptive sensation measuring device 100 in the third embodiment differs from the interoceptive sensation measuring device 100 in the first embodiment in that it allows adjustment of the virtual heart rate phase (VHP) and virtual heart rate cycle (VHC) using means different from those used in the first embodiment. Components identical to those in the first embodiment are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0041] As shown in the lower part of Figure 8, a coordinate system is shown in which the vertical axis represents the heart rate cycle and the horizontal axis represents the heart rate phase, and a point P that can be moved on the coordinate system is shown. The user SB can adjust the virtual heart rate phase VHP of the virtual heart rate VH by dragging point P to the right, and adjust the virtual heart rate phase VHP of the virtual heart rate VH by dragging point P to the left, and adjust the virtual heart rate phase VHP of the virtual heart rate VH by dragging point P to the left, and similarly, the user SB can adjust the virtual heart rate cycle VHC of the virtual heart rate VH by dragging point P to the upward, and adjust the virtual heart rate cycle VHC of the virtual heart rate VH by dragging point P to the downward. The user SB adjusts the virtual heart rate timing VHT by moving point P to synchronize the virtual heart rate phase VHP and virtual heart rate cycle VHC of the virtual heart rate VH with the actual heart rate timing AHT, and then responds with the subjective heart rate timing SHT.

[0042] The interoceptive sensory measurement device 100 described above provides the same effects as the first embodiment. Furthermore, since the user SB can respond with subjective heart rate timing SHT by dragging point P on the coordinate system, they can easily understand how much point P has been moved from its initial position to adjust the virtual heart rate timing VHT. Therefore, for example, even if the user SB accidentally moves point P on the coordinate system, the erroneous operation can be easily reversed by moving point P back to its initial position.

[0043] D. Other embodiments: (D1) In the first embodiment, the subjective heart rate acquisition unit 22 acquires the subjective heart rate timing SHT that the user SB responds to by operating the heart rate phase adjustment unit PA and the heart rate cycle adjustment unit CA, and in the third embodiment, the subjective heart rate timing SHT that the user SB responds to by moving a point P on the coordinate system, but is not limited to these. The subjective heart rate acquisition unit 22 may be configured to acquire the subjective heart rate timing SHT that the user SB responds to by operations such as tapping or swiping via the display unit 10.

[0044] (D2) In each of the above embodiments, the interoceptive sensation measuring device 100 was equipped with a touch-operable display unit 10, but this may be omitted. Instead, for example, the interoceptive sensation measuring device 100 may be equipped with physical buttons such as switches, and may be configured to acquire subjective heart rate timing SHT when the user SB presses a physical button. Alternatively, the interoceptive sensation measuring device 100 may be equipped with a function that can recognize sounds such as vocalizations made by the user SB, and may be configured to acquire subjective heart rate timing SHT when the user SB makes a vocalization.

[0045] (D3) In each of the above embodiments, the actual heart rate acquisition unit 21 was configured as an electrocardiograph, but is not limited thereto. The actual heart rate acquisition unit 21 may be configured as a pulse wave meter capable of detecting changes in blood vessel volume, or as a smartphone camera. If the actual heart rate acquisition unit 21 is configured as a smartphone camera, the actual heart rate timing AHT may be acquired from an image of the user SB's face captured by the camera.

[0046] (D4) In each of the above embodiments, the subjective heart rate acquisition unit 22 was composed of a pressure sensor, but is not limited thereto. The subjective heart rate acquisition unit 22 may be composed of various sensors, such as a capacitive sensor.

[0047] (D5) The configuration of the devices comprising the actual heart rate acquisition unit 21, the subjective heart rate acquisition unit 22, and the interoceptive sensory analysis unit 23 is not limited to the above embodiments. For example, the actual heart rate acquisition unit 21, the subjective heart rate acquisition unit 22, and the interoceptive sensory analysis unit 23 may be comprised of a single smartwatch or a single smartphone. Alternatively, the actual heart rate acquisition unit 21 and the subjective heart rate acquisition unit 22 may be comprised of a single device that is communicatively connected to the device comprising the interoceptive sensory analysis unit 23.

[0048] (D6) In the first and third embodiments, the virtual heart rate timing VHT of the initially presented virtual heart rate VH is such that the virtual heart rate phase VHP is different from the actual heart rate phase AHP and the virtual heart rate cycle VHC is different from the actual heart rate cycle AHC, but is not limited to this. The virtual heart rate timing VHT of the initially presented virtual heart rate VH only needs to be set within a predetermined range, and it is permissible if, by chance, the virtual heart rate phase VHP is set to be the same as the actual heart rate phase AHP, or if the virtual heart rate cycle VHC is set to be the same as the actual heart rate cycle AHC.

[0049] (D7) In the second embodiment, the virtual heart rate timing VHT of the first virtual heart rate VH1 presented initially was, but is not limited to, having a virtual heart rate phase VHP that was different from the actual heart rate phase AHP. The virtual heart rate timing VHT of the first virtual heart rate VH1 presented initially only needs to be set within a predetermined range, and it is permissible if, by chance, the virtual heart rate phase VHP is set to be the same as the actual heart rate phase AHP.

[0050] (D8) In the second embodiment, the display unit 10 displays a first virtual heart rate VH1 in which the virtual heart rate phase VHP is different from the actual heart rate timing AHT, and then displays a second virtual heart rate VH2 in which the virtual heart rate cycle VHC is different from the actual heart rate timing AHT, but is not limited to this. The display unit 10 may display a first virtual heart rate VH1 in which the virtual heart rate cycle VHC is different from the actual heart rate timing AHT, and then display a second virtual heart rate VH2 in which the virtual heart rate phase VHP is different from the actual heart rate timing AHT.

[0051] (D9) In the second embodiment, the virtual heart rate cycle VHC in the virtual heart rate timing VHT of the first virtual heart rate VH1 was set to be the same as the actual heart rate cycle AHC, but is not limited thereto. The virtual heart rate cycle VHC in the virtual heart rate timing VHT of the first virtual heart rate VH1 presented initially may be set to be, for example, a heart rate cycle within a range of ±10% of the actual heart rate cycle AHC.

[0052] (D10) In the first and third embodiments, the virtual heart rate cycle (VHC) of the initially presented virtual heart rate (VH) was set to be presented randomly within a range of at least half and at least twice the actual heart rate cycle (AHC). The virtual heart rate cycle (VHC) of the initially presented virtual heart rate (VH) may be presented in a way that changes periodically within a defined range, for example, and does not have to be presented randomly.

[0053] (D11) In the above embodiment, the interoceptive sensation measuring device 100 was configured as hardware, but is not limited thereto. Alternatively, it may be configured as an interoceptive sensation measuring program that enables a computer to implement a function to acquire actual heart rate timing (AHT), a function to acquire subjective heart rate timing (SHT), and a function to analyze the interoceptive sensation of the user SB based on the actual heart rate timing (AHT) and the subjective heart rate timing (SHT).
