[0013] An example of an embodiment of the present disclosure will be described below with reference to the drawings. In the description of this embodiment, for convenience of explanation, the "left-right direction" and "up-down direction" may be referred to as appropriate. These directions are relative directions set for the display unit 24 of the information processing device 20 illustrated in Figures 3, 5, 6, 7, 9, 10 to 15. Here, the "left-right direction" includes the "left direction" and the "right direction." The "up-down direction" includes the "up direction" and the "down direction." In each figure, the symbol U indicates the up direction. The symbol D indicates the down direction. The symbol L indicates the left direction. The symbol R indicates the right direction.

[0014] (First embodiment) An information processing system 1 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of the information processing system 1 according to the first embodiment. The information processing system 1 is used, for example, in a medical facility such as a hospital. As illustrated in Fig. 1, the information processing system 1 includes a sensor 10 and an information processing device 20. The sensor 10 and the information processing device 20 are connected by wire or wirelessly.

[0015] The sensor 10 measures biological information of the subject. The sensor 10 includes, for example, a blood pressure sensor, a respiration sensor, an SpO2 sensor, a body temperature sensor, and a heart rate sensor. The blood pressure sensor measures the subject's blood pressure (systolic blood pressure, diastolic blood pressure, and mean blood pressure). The blood pressure sensor is, for example, a sphygmomanometer or a catheter for measuring invasive blood pressure values. The respiration sensor measures the subject's respiratory rate, etc. The respiration sensor is, for example, an electrode for measuring the respiratory rate. The SpO2 sensor measures the subject's transcutaneous arterial oxygen saturation (SpO2). The SpO2 sensor is, for example, a probe for measuring SpO2. The body temperature sensor measures the subject's body temperature. The body temperature sensor is, for example, a thermometer for measuring the subject's body temperature or a temperature probe connected to a thermometer. The heart rate sensor measures the subject's heart rate. The heart rate sensor is, for example, an electrode for measuring the heart rate. In this embodiment, the sensor 10 measures the biological information by a passive method, but the biological information may also be measured by an active method. When measuring biological information by a passive method, for example, the sensor 10 measures the biological information by receiving a signal from an object without emitting a signal such as light or electromagnetic waves to the object. When measuring biological information by an active method, for example, the sensor 10 measures the biological information by emitting a signal to the object and receiving the signal reflected by or transmitted through the object. The biological information measured by the sensor 10 is input to the information processing device 20 as an electrical signal.

[0016] The information processing device 20 is, for example, a bedside monitor. The information processing device 20 includes an input interface 21, a storage unit 22, a control unit 23, and a display unit 24. These are connected to each other via a bus 25 so as to be able to communicate with each other.

[0017] The input interface 21 is configured to receive input of the subject's biometric information measured by the sensor 10. When the biometric information is input to the input interface 21, the input interface 21 generates date and time information indicating the date and time when the biometric information was input to the input interface 21. In this embodiment, the date and time information is used as information indicating the measurement date and time of the biometric information. For example, when the sensor 10 and the information processing device 20 are electrically connected via a cable, the input interface 21 identifies the type of sensor 10 based on the type of connection port of the information processing device 20 to which the cable is connected, and generates type information of the sensor 10. The input interface 21 associates the biometric information, date and time information, and type information, and then transmits this information to the control unit 23.

[0018] The storage unit 22 may be configured with a storage device (storage) such as a hard disk drive (HDD), a solid state drive (SSD), or a flash memory. The storage unit 22 stores biological information, date and time information, reference information, name information, change reference information, and the like. The reference information is, for example, information indicating a reference value for determining whether a value indicated by the biological information is normal. The reference value for determining whether a value indicated by the biological information is normal is a value defined in medical guidelines or the like, and is, for example, a reference value for determining whether a value indicated by the biological information indicates a normal condition of a subject. For example, if the biological information is heart rate, the normal range for heart rate is 60 to 100 bpm, so such reference values ​​are 60 bpm (lower reference value) and 100 bpm (upper reference value). For example, if the biological information is systolic blood pressure, such reference values ​​are 100 mmHg (lower reference value) and 140 mmHg (upper reference value). For example, if the biological information is diastolic blood pressure, such reference values ​​are 60 mmHg (lower limit reference value) and 90 mmHg (upper limit reference value). For example, if the biological information is mean blood pressure, such reference values ​​are 75 mmHg (lower limit and upper limit reference value) and 110 mmHg (upper limit reference value). The name information is information indicating the name of the biological information of the subject. Examples of the name of the biological information include heart rate, systolic blood pressure, diastolic blood pressure, mean blood pressure, respiratory rate, percutaneous arterial oxygen saturation, body temperature, etc. The change reference information is information indicating the criteria for determining whether a change has occurred in the biological information of the subject. The memory unit 22 can transmit various information to the control unit 23, for example, in response to an instruction signal from the control unit 23.

[0019] The control unit 23 includes, as its hardware configuration, a memory 231 and a processor 232. The memory 231 is configured, for example, from a ROM (Read Only Memory) in which various computer programs and the like are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs and the like executed by the processor 232 are stored. The processor 232 is, for example, a CPU (Central Processing Unit), and is configured to load a computer program specified from the various computer programs stored in the ROM onto the RAM and execute various processes in cooperation with the RAM.

[0020] A computer program can be stored in, for example, various types of non-transitory computer-readable media and supplied to a computer. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), and flash ROMs).

[0021] The control unit 23 generates an instruction signal for causing the storage unit 22 to transmit various pieces of information stored in the storage unit 22 to the control unit 23. The control unit 23 transmits the generated instruction signal to the storage unit 22.

[0022] The control unit 23 generates name information based on the type information received from the input interface 21. The control unit 23 can transmit the generated name information to the storage unit 22.

[0023] The control unit 23 generates condition information for each predetermined unit period based on the biological information, date and time information, and reference information, indicating whether the value indicated by the biological information indicates that the subject's condition is normal. The predetermined unit period may be, for example, an hourly unit, a daily unit, or a monthly unit. For example, if the number of biological information values ​​indicating a value outside the normal range in a given day is less than a predetermined value, the control unit 23 generates condition information indicating that the subject's condition is good. On the other hand, for example, if the number of biological information values ​​indicating a value outside the normal range in a given day is equal to or greater than a predetermined value, the control unit 23 generates condition information indicating that the subject's condition is poor. The control unit 23 can transmit the generated condition information to the storage unit 22.

[0024] The control unit 23 classifies the biometric information input to the input interface 21 into a first biometric information group including biometric information from at least a first period, a second biometric information group including biometric information from a second period, and a third biometric information group including biometric information from a third period. In this embodiment, the second period is a period different from the first period and is a period temporally later than the first period. The third period is a period different from the first and second periods and is a period temporally later than the second period. At least two of the first period, second period, and third period may overlap with each other.

[0025] In this embodiment, the current time is assumed to be 0:00 on March 4, 2024. For example, if the first period is from 0:00 on March 2, 2024 to 23:59 on the same day, the second period is from 0:00 on March 3, 2024 to 23:59 on the same day, and the third period is from 0:00 on March 4, 2024 to 23:59 on the same day, the control unit 23 classifies the biometric information for the period from 0:00 on March 2, 2024 to 23:59 on March 4, 2024 into a first biometric information group including the biometric information on March 2, 2024, a second biometric information group including the biometric information on March 3, 2024, and a third biometric information group including the biometric information on March 4, 2024. In this embodiment, the 24 hours (one day) immediately preceding the current time is set as the third period, the 24 hours (one day) immediately preceding the third period is set as the second period, and the 24 hours (one day) immediately preceding the second period is set as the first period. Note that the first period, second period, and third period may be the same length or different lengths. Furthermore, the first period, second period, and third period are not limited to days, and may be, for example, monthly or predetermined time units.

[0026] The control unit 23 generates a plurality of pieces of change trend information indicating a change trend in the subject's biological information from one period to another, based on the biological information of the subject input to the input interface 21. In this embodiment, the control unit 23 determines whether a change has been observed in the subject's biological information based on the biological information and the change reference information, and generates a plurality of pieces of change trend information based on the determination and the biological information.

[0027] The control unit 23 generates initial change trend information (an example of change trend information) based on, for example, all of the biometric information included in the first biometric information group or a portion of the biometric information included in the first biometric information group. The portion of the biometric information included in the first biometric information group is, for example, biometric information input to the input interface 21 for a predetermined time (e.g., 30 minutes) from the time when the subject's biometric information began to be input to the input interface 21 (input start time). The initial change trend information is change trend information indicating a change trend in the subject's biometric information from one period to another period on the day when the subject's biometric information began to be input. The control unit 23 generates first change trend information (an example of change trend information) indicating a change trend in the subject's biometric information from the first period to the second period based on, for example, the first biometric information group and the second biometric information group. The control unit 23 generates second change trend information (an example of change trend information) indicating a change trend in the subject's biometric information from the second period to the third period based on, for example, the second biometric information group and the third biometric information group.

[0028] The initial change trend information is generated, for example, based on the difference between the value indicated by the biological information input into the input interface 21 at the input start time and the value indicated by the biological information input into the input interface 21 30 minutes after the input start time. Note that this difference is, for example, a value (initial comparison value) obtained by subtracting the value indicated by the biological information input into the input interface 21 at the input start time from the value indicated by the biological information input into the input interface 21 30 minutes after the input start time. Based on this difference and the change reference information, the control unit 23 determines whether a change has occurred in the subject's biological information over the 30 minutes from the input start time. The control unit 23 generates the initial change trend information based on this determination and the initial comparison value.

[0029] The first change trend information is generated based on a first comparison value calculated from a first value based on the first biological information group and a second value based on the second biological information group. The second change trend information is generated based on a second comparison value calculated from a second value based on the second biological information group and a third value based on the third biological information group. For example, the first value is the sum of the values ​​indicated by each piece of biological information included in the first biological information group. The second value is the sum of the values ​​indicated by each piece of biological information included in the second biological information group. The third value is the sum of the values ​​indicated by each piece of biological information included in the third biological information group. For example, the first comparison value is the difference between the first value and the second value (the value obtained by subtracting the first value from the second value), and the second comparison value is the difference between the second value and the third value (the value obtained by subtracting the second value from the third value). In this embodiment, the control unit 23 determines whether a change has occurred in the subject's biological information from the first period to the second period based on the first comparison value and the change reference information. The control unit 23 generates the first change trend information based on this determination and the first comparison value. Furthermore, the control unit 23 determines whether or not a change is observed in the biological information of the subject from the second time period to the third time period based on the second comparison value and the change reference information. The control unit 23 generates second change trend information based on the determination and the second comparison value.

[0030] Based on the generated plurality of pieces of change trend information, the control unit 23 generates display data in which the plurality of pieces of change trend information are displayed side by side or overlapping. For example, when the control unit 23 generates display data based on initial change trend information, first change trend information, and second change trend information, the initial change trend information, first change trend information, and second change trend information are displayed side by side or overlapping in the display data. In this embodiment, the change trend information is displayed as a slanted figure in the display data. Note that, although an arrow-shaped figure is used as an example of a slanted figure in this specification, slanted figures are not limited to arrow-shaped figures. Also, in this specification, a horizontal arrow-shaped figure pointing right (see first figure D1 in FIG. 3 ) is defined as a reference figure, and the direction in which the reference figure faces (horizontal direction) is defined as a reference direction. In this specification, "slant" refers to the inclination relative to the reference direction. Therefore, the slanted right-pointing horizontal arrow-shaped figure is zero. In this specification, a figure with zero inclination is also included in the definition of a slanted figure. In this embodiment, the control unit 23 generates display data including name information and transmits the generated display data to the display unit 24.

[0031] The display mode of the initial change trend information changes depending on the initial comparison value. The display mode of the first change trend information changes depending on the first comparison value. The display mode of the second change trend information changes depending on the second comparison value. For example, if the initial change trend information is displayed as an arrow-shaped graphic in the display data, the slope of the arrow-shaped graphic corresponding to the initial change trend information changes depending on the initial comparison value. For example, if the first change trend information is displayed as an arrow-shaped graphic in the display data, the slope of the arrow-shaped graphic corresponding to the first change trend information changes depending on the first comparison value. For example, if the second change trend information is displayed as an arrow-shaped graphic in the display data, the slope of the arrow-shaped graphic corresponding to the second change trend information changes depending on the second comparison value. In other words, the change in display mode here refers to a change in the slope of the arrow-shaped graphic.

[0032] The display mode of each arrow-shaped figure corresponding to the initial change trend information, the first change trend information, and the second change trend information is determined based on the condition information. For example, if the condition information indicates that the subject's condition is good, the arrow-shaped figure is colored light red, whereas if the condition information indicates that the subject's condition is poor, the arrow-shaped figure is colored dark red. In other words, the display mode of the arrow-shaped figure here refers to the shade of the color applied to the arrow-shaped figure.

[0033] The display unit 24 is, for example, a display such as a liquid crystal display, an organic EL display, etc. The display unit 24 displays an image based on display data received from the control unit 23, for example.

[0034] (First Example of First Embodiment) Next, an information processing method according to a first example of the first embodiment will be described with reference to Figures 2 and 3. Figure 2 is a flowchart showing an example of an information processing method up to the point where an image 100 based on display data is displayed on the display unit 24 of the information processing device 20. Figure 3 is a diagram showing an example of an image 100 based on display data. Note that the premise of this example described hereinafter also applies to subsequent examples unless otherwise specified.

[0035] In this embodiment, the biological information is the heart rate. Therefore, unless otherwise specified, in this embodiment, "biological information" refers to the heart rate. In this embodiment, the sensor 10 measures biological information related to the heart rate in one-minute increments. In this embodiment, the sensor 10 and the information processing device 20 are electrically connected via a cable, and the input interface 21 identifies the type of sensor 10 according to the type of connection port of the information processing device 20 to which the cable is connected, and generates type information of the sensor 10.

[0036] In this embodiment, the control unit 23 classifies the biometric information input to the input interface 21 into a first biometric information group including biometric information in a first period, a second biometric information group including biometric information in a second period, and a third biometric information group including biometric information in a third period. The first period is from 0:00 to 23:59 on March 2, 2024, the second period is from 0:00 to 23:59 on March 3, 2024, and the third period is from 0:00 to 23:59 on March 4, 2024. Thus, in this embodiment, the first period, second period, and third period are of the same length.

[0037] In this embodiment, the control unit 23 generates the initial change trend information based on the biometric information input to the input interface 21 from 0:00 to 0:30 on March 2, 2024. However, the control unit 23 may also generate the initial change trend information based on the biometric information input to the input interface 21 from 0:00 to 23:59 on March 2, 2024, for example. Also, in this embodiment, the values ​​indicated by the biometric information input to the input interface 21 at 0:00 on March 2, 2024 and the biometric information input to the input interface 21 at 0:30 on the same day are both 60 times.

[0038] In this embodiment, the first value is the sum of the values ​​indicated by each piece of biometric information included in the first biometric information group, and is 116,000 times / day. The second value is the sum of the values ​​indicated by each piece of biometric information included in the second biometric information group, and is 135,000 times / day. The third value is the sum of the values ​​indicated by each piece of biometric information included in the third biometric information group, and is 158,000 times / day.

[0039] In this embodiment, the change trend information is displayed as a tilted arrow-shaped graphic. If the value obtained by subtracting the value indicated by the biometric information 30 minutes after the input start time from the value indicated by the biometric information at the input start time is less than -10, the control unit 23 tilts the arrow-shaped graphic corresponding to the initial change trend information downward from the reference direction in accordance with the value. If the value obtained by subtracting the value indicated by the biometric information 30 minutes after the input start time from the value indicated by the biometric information at the input start time is greater than or equal to -10 and less than +10, the control unit 23 sets the tilt of the arrow-shaped graphic corresponding to the initial change trend information to zero (making the graphic horizontal with respect to the reference direction) in accordance with the value. If the value obtained by subtracting the value indicated by the biometric information 30 minutes after the input start time from the value indicated by the biometric information at the input start time is greater than or equal to +10, the control unit 23 tilts the arrow-shaped graphic corresponding to the initial change trend information upward from the reference direction in accordance with the value. If the value obtained by subtracting the sum of the values ​​indicated by each piece of biometric information on the day before the given day from the sum of the values ​​indicated by each piece of biometric information on the day before the given day is −15,000, the control unit 23 tilts the arrow-shaped graphic corresponding to the first change trend information or the second change trend information downward from the reference direction in accordance with the value. If the value obtained by subtracting the sum of the values ​​indicated by each piece of biometric information on the day before the given day from the sum of the values ​​indicated by each piece of biometric information on the day before the given day is greater than or equal to −15,000 and less than +15,000, the control unit 23 sets the tilt of the arrow-shaped graphic corresponding to the first change trend information or the second change trend information to zero (making the graphic horizontal with respect to the reference direction). If the value obtained by subtracting the sum of the values ​​indicated by each piece of biometric information on the day before the given day from the sum of the values ​​indicated by each piece of biometric information on the day before the given day is greater than or equal to +15,000, the control unit 23 tilts the arrow-shaped graphic corresponding to the first change trend information or the second change trend information upward from the reference direction in accordance with the value.

[0040] In this embodiment, generation of condition information is performed on a daily basis, and the predetermined value for the number of pieces of biological information showing values ​​outside the normal range on a given day is 100. Furthermore, in this embodiment, the number of pieces of biological information showing values ​​outside the normal range on March 2, 2024 is 0. The number of pieces of biological information showing values ​​outside the normal range on March 3, 2024 is 50. The number of pieces of biological information showing values ​​outside the normal range on March 4, 2024 is 200. Furthermore, if the condition information indicates that the subject's condition is good, the arrow-shaped figure corresponding to the change trend information for the period corresponding to the condition information is colored light red, whereas if the condition information indicates that the subject's condition is poor, the arrow-shaped figure corresponding to the change trend information for the period corresponding to the condition information is colored dark red.

[0041] 2, biological information measured by the sensor 10 is input to the input interface 21 of the information processing device 20 (STEP 01). In this embodiment, biological information measured by the sensor 10 during the period from 0:00 on March 2, 2024 to 23:59 on March 4, 2024 is input to the input interface 21 sequentially for each processing unit time as time passes. The processing unit time is, for example, one hour, one minute, one second, etc.

[0042] When biometric information is input to the input interface 21, the input interface 21 generates date and time information indicating the date and time when the biometric information was input to the input interface 21 (STEP 02).

[0043] The input interface 21 identifies the type of sensor 10 according to the type of connection port of the information processing device 20 to which the cable connecting the sensor 10 and the information processing device 20 is connected, and generates type information of the sensor 10 (STEP 03). In this embodiment, the biological information input to the input interface 21 is a heart rate, so the input interface 21 generates type information indicating that the sensor 10 is a heart rate sensor.

[0044] The input interface 21 links the biometric information, date and time information, and type information, and then transmits this information to the control unit 23 (STEP 04).

[0045] The control unit 23 generates name information based on the type information received from the input interface 21 (STEP 05). In this embodiment, since the biological information input to the input interface 21 is the heart rate, the control unit 23 generates name information indicating that the name of the biological information is the heart rate.

[0046] The control unit 23 generates condition information on a daily basis based on the biological information and the reference information (STEP 06). In this embodiment, the biological information input to the input interface 21 is heart rate, so the control unit 23 determines whether the value indicated by the biological information is within the range of 60 to 100 beats per minute (normal heart rate range). In this embodiment, the number of pieces of biological information indicating values ​​outside the normal range on March 2, 2024 (0) and the number of pieces of biological information indicating values ​​outside the normal range on March 3, 2024 (50) are less than the predetermined value (100). On the other hand, the number of pieces of biological information indicating values ​​outside the normal range on March 4, 2024 (200) is equal to or greater than the predetermined value (100). Therefore, the control unit 23 generates condition information indicating that the subject's condition is good on March 2, 2024 and March 3, 2024, and condition information indicating that the subject's condition is poor on March 4, 2024.

[0047] The control unit 23 classifies the biometric information input to the input interface 21 into a first biometric information group including biometric information in a first period, a second biometric information group including biometric information in a second period, and a third biometric information group including biometric information in a third period (STEP 07). In this embodiment, the control unit 23 classifies the biometric information input to the input interface 21 into a first biometric information group including biometric information as of March 2, 2024, a second biometric information group including biometric information as of March 3, 2024, and a third biometric information group including biometric information as of March 4, 2024.

[0048] The control unit 23 generates initial change trend information based on all of the biometric information included in the first biometric information group or a portion of the biometric information included in the first biometric information group (STEP 08). In this embodiment, the control unit 23 generates initial change trend information based on the biometric information input into the input interface 21 at 0:00 on March 2, 2024 and the biometric information input into the input interface 21 at 0:30 on the same day. In this embodiment, the values ​​indicated by the biometric information (heart rate) input into the input interface 21 at 0:00 on March 2, 2024 and the biometric information input into the input interface 21 at 0:30 on the same day are both 60 times. Therefore, the value obtained by subtracting the value indicated by the biometric information input into the input interface 21 at 0:00 on March 2, 2024 from the value indicated by the biometric information input into the input interface 21 at 0:30 on March 2, 2024 is 0 (i.e., greater than or equal to -10 and less than +10). Therefore, the control unit 23 generates initial change trend information indicating that the change trend of the subject's biological information from 0:00 to 0:30 on Mar. 2, 2024 will remain flat.

[0049] The control unit 23 generates first change trend information indicating a change trend in the subject's biological information from the first period to the second period based on the first biological information group and the second biological information group (STEP 09). More specifically, the control unit 23 generates the first change trend information based on a first comparison value calculated from a first value based on the first biological information group and a second value based on the second biological information group. In this embodiment, the first value is 116,000 times / day and the second value is 135,000 times / day, so the first comparison value is +19,000. In other words, since the first comparison value is +15,000 or greater, the control unit 23 tilts the arrow-shaped figure upward from the reference direction in accordance with the first comparison value. Therefore, the control unit 23 generates first change trend information indicating that the change trend in the subject's biological information from March 2, 2024 to March 3, 2024 is an upward trend.

[0050] The control unit 23 generates second change trend information indicating a change trend in the subject's biological information from the second period to the third period based on the second biological information group and the third biological information group (STEP 10). More specifically, the control unit 23 generates the second change trend information based on a second comparison value calculated from a second value based on the second biological information group and a third value based on the third biological information group. In this embodiment, the second value is 135,000 times / day and the third value is 158,000 times / day, so the second comparison value is +23,000. In other words, since the second comparison value is greater than or equal to +15,000, the control unit 23 tilts the arrow-shaped figure upward from the reference direction in accordance with the second comparison value. Therefore, the control unit 23 generates second change trend information indicating that the change trend in the subject's biological information from March 3, 2024 to March 4, 2024 is an upward trend. Since the second comparison value is greater than the first comparison value, the inclination of the arrow-shaped graphic corresponding to the second change trend information is greater than the inclination of the arrow-shaped graphic corresponding to the first change trend information.

[0051] The control unit 23 generates display data based on the name information, condition information, initial change trend information, first change trend information, and second change trend information (STEP 11). In this embodiment, the display data includes biological information and name information.

[0052] The control unit 23 transmits the generated display data to the display unit 24 (STEP 12). When the display data is transmitted to the display unit 24, the image 100 illustrated in Fig. 3 is displayed on the display unit 24 (STEP 13).

[0053] Here, with reference to Fig. 3, an image 100 based on the display data displayed on the display unit 24 will be described. As illustrated in Fig. 3, the image 100 includes a first name M1, a first axis AX1, a second axis AX2, a heart rate graph object G1, a first graphic D1, a second graphic D2, and a third graphic D3. Note that, for example, if the heart rate is 60 beats per minute, 60 is the value related to the biometric information (heart rate in this example). In other words, the value related to the biometric information is the magnitude, level, etc. indicated by the biometric information.

[0054] The first name M1 is based on name information related to the heart rate. Therefore, the first name M1 is the heart rate. The first name M1 is displayed in the upper left corner of the display unit 24. The first axis AX1 is a time axis and extends horizontally (left and right in FIG. 3). The second axis AX2 indicates values ​​related to biological information (heart rate) and extends vertically (up and down in FIG. 3).

[0055] The heart rate graph object G1 corresponds to biological information related to the heart rate. The heart rate graph object G1 indicates the magnitude of each heart rate. The heart rate graph object G1 is displayed in a first region R1 defined by a first axis AX1 and a second axis AX2. In a left region R11 located on the left side of the first region R1, a graph object corresponding to biological information related to the heart rate on March 2, 2024, from the heart rate graph object G1, is displayed. In a central region R12 located in the center of the first region R1, a graph object corresponding to biological information related to the heart rate on March 3, 2024, from the heart rate graph object G1, is displayed. In a right region R13 located on the right side of the first region R1, a graph object corresponding to biological information related to the heart rate on March 4, 2024, from the heart rate graph object G1, is displayed.

[0056] The first graphic D1 corresponds to the initial change trend information. The second graphic D2 corresponds to the first change trend information. The third graphic D3 corresponds to the second change trend information. The first graphic D1, the second graphic D2, and the third graphic D3 are displayed above the graph object corresponding to the biometric information related to the heart rate on March 4, 2024, in the heart rate graph object G1. That is, the first graphic D1, the second graphic D2, and the third graphic D3 are displayed in the upper right portion of the display unit 24. However, the display positions of the first graphic D1, the second graphic D2, and the third graphic D3 are not limited to this example. For example, the first graphic D1, the second graphic D2, and the third graphic D3 may be displayed in the upper left portion or the upper center portion of the display unit 24. The first graphic D1, the second graphic D2, and the third graphic D3 are displayed side by side, and the arrangement order of the first graphic D1, the second graphic D2, and the third graphic D3 indicates the chronological order. That is, a plurality of pieces of change trend information are displayed side by side in the display data, and the arrangement order of the plurality of pieces of change trend information indicates the chronological order of the change trend information.

[0057] The first graphic D1, the second graphic D2, and the third graphic D3 are inclined. The first graphic D1, the second graphic D2, and the third graphic D3 are displayed in the shape of an arrow. The initial change trend information indicates that the change trend of the subject's biological information from 0:00 to 0:30 on March 2, 2024 is flat, so the slope of the first graphic D1 is zero (i.e., horizontal with respect to the reference direction). On the other hand, the first change trend information indicates that the change trend of the subject's biological information from March 2, 2024 to March 3, 2024 is an upward trend, so the second graphic D2 is inclined upward from the reference direction. Furthermore, the second change trend information indicates that the change trend of the subject's biological information from March 3, 2024 to March 4, 2024 is an upward trend, so the third graphic D3 is inclined upward from the reference direction. Furthermore, since the second comparison value is greater than the first comparison value, the slope of the third graphic D3 is greater than the slope of the second graphic D2. In this way, the slope of each figure corresponding to each piece of change trend information indicates the amount of change in the subject's biological information from one period to another.

[0058] In this embodiment, the display modes of the first graphic D1, the second graphic D2, and the third graphic D3 (the shade of the color applied to the first graphic D1, the second graphic D2, and the third graphic D3) are determined based on the condition information. In this embodiment, the condition information for March 2, 2024 and March 3, 2024 indicates that the subject's condition is good, while the condition information for March 4, 2024 indicates that the subject's condition is poor. Therefore, the first graphic D1 and the second graphic D2 are colored light red, while the third graphic D3 is colored dark red. Note that in FIG. 3, the shade of the color is represented by the number of hatched lines. In this way, the display modes of the first graphic D1, the second graphic D2, and the third graphic D3 are determined based on the biometric information and the reference information.

[0059] Incidentally, in order to accurately recognize the condition of a subject, it is important to understand not only the subject's biometric information but also the changing trends in the subject's biometric information. However, it may be difficult to immediately grasp the changing trends at a glance of the subject's biometric information.

[0060] According to the information processing device 20 having the above configuration, the information processing device 20 generates, based on the subject's biological information, a plurality of pieces of change trend information indicating change trends in the subject's biological information from one period to another. The information processing device 20 then generates display data in which the generated plurality of pieces of change trend information are displayed side by side. A user, such as a medical professional, can intuitively and accurately grasp the change trends in the subject's biological information by visually viewing an image 100 based on such display data. Therefore, the information processing device 20 can assist the user in intuitively and accurately grasping the change trends in the subject's biological information. Furthermore, the information processing method, computer program, and non-transitory computer-readable medium having the above configuration can also achieve similar effects.

[0061] Furthermore, according to the information processing device 20 having the above configuration, the change trend information is displayed in the display data as a graphic having a slope, and the slope indicates the amount of change in the biometric information from one period to another. Furthermore, the display mode of the graphic is determined based on the biometric information and reference information indicating a reference value for determining whether the value indicated by the biometric information is normal. Therefore, by using the display data generated by the information processing device 20, the user can immediately grasp the amount of change in the biometric information and whether the value indicated by the biometric information is normal.

[0062] Furthermore, according to the information processing device 20 having the above configuration, a plurality of pieces of change trend information in the display data are displayed side by side, and the arrangement order of the plurality of pieces of change trend information indicates the chronological order of the change trend information. Therefore, for example, by visually checking the image 100 based on such display data, the user can grasp the change trend of the subject's biological information in chronological order.

[0063] Furthermore, according to the information processing device 20 having the above configuration, the information processing device 20 generates first change trend information indicating a change trend in the subject's biometric information from the first period to the second period based on the first biometric information group and the second biometric information group. Furthermore, the information processing device 20 generates second change trend information indicating a change trend in the subject's biometric information from the second period to the third period based on the second biometric information group and the third biometric information group. The first change trend information and the second change trend information are displayed side by side in the display data. For example, by visually viewing the image 100 based on such display data, the user can intuitively and accurately grasp the change trend in the subject's biometric information from the first period to the second period and the change trend in the subject's biometric information from the second period to the third period. Therefore, the information processing device 20 can assist the user in intuitively and accurately grasping the change trend in the subject's biometric information over multiple periods.

[0064] Furthermore, according to the information processing device 20 having the above configuration, the first change trend information is generated based on a first comparison value calculated from the first value and the second value, and the second change trend information is generated based on a second comparison value calculated from the second value and the third value. In this way, the first change trend information and the second change trend information are calculated from the first comparison value or the second comparison value, which are objective information, so that the user can grasp the change trend of the subject's biological information based on objective information.

[0065] Furthermore, according to the information processing device 20 having the above configuration, the first comparison value is the difference between the first value and the second value, and the second comparison value is the difference between the second value and the third value, so that the first change trend information and the second change trend information can be generated through relatively simple information processing.

[0066] Furthermore, according to the information processing device 20 having the above configuration, the display mode of the first change trend information changes depending on the first comparison value, and the display mode of the second change trend information changes depending on the second comparison value. Therefore, for example, by visually viewing the image 100 based on such display data, the user can intuitively and easily grasp the degree of change trend of the subject's biological information.

[0067] Furthermore, according to the information processing device 20 having the above configuration, the display data includes biological information. Therefore, for example, by visually viewing the image 100 based on such display data, the user can grasp the biological information (graph object corresponding to the biological information) as well as the change trend of the biological information of the subject. Therefore, for example, by visually viewing the image 100 based on such display data, the user can more accurately grasp the change trend of the biological information of the subject.

[0068] Furthermore, according to the information processing device 20 having the above configuration, the change trend information is displayed in the form of an arrow in the display data, so that the user can intuitively and easily recognize the change trend of the subject's biometric information.

[0069] Furthermore, according to the information processing device 20 having the above configuration, the display data includes name information indicating the name of the subject's biometric information. Therefore, by visually checking the image 100 based on such display data, the user can recognize which biometric information is showing a change trend, and then grasp the change trend.

[0070] (Second Example of the First Embodiment) Next, an information processing method according to a second example of the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a flowchart illustrating an example of an information processing method up to the point where an image 200 based on display data is displayed on the display unit 24 of the information processing device 20. FIG. 5 is a diagram illustrating an example of an image 200 based on display data. In this example, parts similar to those in the first example of the first embodiment will be described using the same reference numerals as in the first example of the first embodiment, and descriptions of overlapping parts will be omitted as appropriate. This example differs from the first example of the first embodiment in that the control unit 23 executes the information processing method illustrated in FIG. 4 instead of the information processing method illustrated in FIG. 2.

[0071] In this embodiment, two types of biometric information measured by the sensor 10 are input to the input interface 21. In this embodiment, the biometric information input to the input interface 21 is heart rate and mean blood pressure. However, the biometric information input to the input interface 21 may be, for example, heart rate and diastolic blood pressure, or heart rate and systolic blood pressure. In this embodiment, the sensor 10 measures the heart rate every minute and the mean blood pressure every 30 minutes. The input interface 21 transmits the two types of input biometric information to the control unit 23. In this embodiment, the input interface 21 also generates date and time information and type information of the sensor 10. However, in this embodiment, the input interface 21 generates date and time information and type information of the sensor 10 for each type of biometric information. In addition, the input interface 21 links the biometric information, date and time information, and type information for each type of biometric information and transmits this information to the control unit 23.

[0072] In this embodiment, the control unit 23 generates a plurality of pieces of change trend information for each type of biometric information based on two types of biometric information. In this embodiment, the control unit 23 also generates display data. However, in this embodiment, the display data generated by the control unit 23 displays the plurality of pieces of change trend information side by side for each type of biometric information.

[0073] In this example, two types of biological information from 0:00 to 0:30 on March 2, 2024 are input to the input interface 21. Note that the various pieces of information related to the heart rate in this example are the same as the various pieces of information related to the heart rate in the first example of the first embodiment. Meanwhile, various pieces of information related to the mean blood pressure will be described later.

[0074] In this embodiment, the value of the mean blood pressure input into the input interface 21 at 0:00 on March 2, 2024 is 105 mmHg, and the value of the mean blood pressure input into the input interface 21 at 0:30 on the same day is 100 mmHg.

[0075] In this embodiment, the first value of mean blood pressure is the sum of the values ​​indicated by each piece of biological information included in the first biological information group, which is 4600 mmHg / day. The second value of mean blood pressure is the sum of the values ​​indicated by each piece of biological information included in the second biological information group, which is 4300 mmHg / day. The third value of mean blood pressure is the sum of the values ​​indicated by each piece of biological information included in the third biological information group, which is 3850 mmHg / day.

[0076] In this embodiment, the change trend information regarding the mean blood pressure is displayed as an inclined arrow-shaped graphic. If the value obtained by subtracting the mean blood pressure 30 minutes after the input start time from the mean blood pressure at the input start time is less than -10, the control unit 23 tilts the arrow-shaped graphic corresponding to the initial change trend information downward from the reference direction in accordance with the value. If the value obtained by subtracting the mean blood pressure 30 minutes after the input start time from the mean blood pressure at the input start time is greater than or equal to -10 and less than +10, the control unit 23 sets the inclination of the arrow-shaped graphic corresponding to the initial change trend information to zero (making the graphic horizontal with respect to the reference direction) in accordance with the value. If the value obtained by subtracting the mean blood pressure 30 minutes after the input start time from the mean blood pressure at the input start time is greater than or equal to +10, the control unit 23 tilts the arrow-shaped graphic corresponding to the initial change trend information upward from the reference direction in accordance with the value. If the value obtained by subtracting the sum of the mean blood pressures on the day before from the sum of the mean blood pressures on that day is less than −500, the control unit 23 tilts the arrow-shaped graphic corresponding to the first change trend information or the second change trend information downward from the reference direction according to the value. If the value obtained by subtracting the sum of the mean blood pressures on the day before from the sum of the mean blood pressures on that day is greater than or equal to −500 and less than +500, the control unit 23 sets the tilt of the arrow-shaped graphic corresponding to the first change trend information or the second change trend information to zero (making the graphic horizontal with respect to the reference direction). If the value obtained by subtracting the sum of the mean blood pressures on the day before from the sum of the mean blood pressures on that day is greater than or equal to +500, the control unit 23 tilts the arrow-shaped graphic corresponding to the first change trend information or the second change trend information upward from the reference direction according to the value.

[0077] In this embodiment, generation of condition information related to mean blood pressure is performed on a daily basis, and the predetermined value for the number of mean blood pressures showing values ​​outside the normal range on a given day is 24. In addition, in this embodiment, the number of mean blood pressures showing values ​​outside the normal range on March 2, 2024, the number of mean blood pressures showing values ​​outside the normal range on March 3, 2024, and the number of mean blood pressures showing values ​​outside the normal range on March 4, 2024 are all assumed to be 0. Regarding mean blood pressure, if the condition information indicates that the subject's condition is good, the arrow-shaped figure corresponding to the change trend information for the period corresponding to the condition information is colored light red, whereas if the condition information indicates that the subject's condition is poor, the arrow-shaped figure corresponding to the change trend information for the period corresponding to the condition information is colored dark red.

[0078] 4, two types of biological information (heart rate and mean blood pressure) measured by the sensor 10 are input to the input interface 21 of the information processing device 20 (STEP 21). In this embodiment, the two types of biological information measured by the sensor 10 during the period from 0:00 on March 2, 2024 to 23:59 on March 4, 2024 are input to the input interface 21 sequentially for each processing unit time as time passes.

[0079] STEP 22 to STEP 30 are the same as STEP 02 to STEP 10 in the first example of the first embodiment. However, in this example, the input interface 21 generates not only date / time information and type information related to the heart rate, but also information related to the mean blood pressure (STEP 22 and STEP 23). The input interface 21 links the biological information related to the heart rate and the mean blood pressure with the date / time information and type information, and transmits this information to the control unit 23 (STEP 24). Furthermore, in this example, the control unit 23 generates not only name information and condition information related to the heart rate, but also information related to the mean blood pressure (STEP 25 and STEP 26). The control unit 23 classifies not only the biological information related to the heart rate, but also the biological information related to the mean blood pressure into a first biological information group, a second biological information group, and a third biological information group (STEP 27). The control unit 23 generates not only the initial change trend information, the first change trend information, and the second change trend information related to the heart rate, but also the information related to the mean blood pressure (STEPs 28 to 30).

[0080] Here, the generation of the condition information, initial change trend information, first change trend information, and second change trend information related to mean blood pressure in this embodiment will be described in detail. In this embodiment, the number of mean blood pressures showing values ​​outside the normal range from March 2, 2024 to March 4, 2024 is all 0, which is less than the predetermined value (24). Therefore, the control unit 23 generates condition information related to mean blood pressure indicating that the subject's condition is good from March 2, 2024 to March 4, 2024 (STEP 26).

[0081] In this embodiment, the mean blood pressure input to the input interface 21 at 0:00 on March 2, 2024 is 105 mmHg, and the mean blood pressure input to the input interface 21 at 0:30 on the same day is 100 mmHg. Therefore, the value obtained by subtracting the mean blood pressure input to the input interface 21 at 0:00 on March 2, 2024 from the mean blood pressure input to the input interface 21 at 0:30 on March 2, 2024 is −5 (i.e., greater than or equal to −10 and less than +10). Therefore, the control unit 23 generates initial change trend information indicating that the change trend of the mean blood pressure from 0:00 on March 2, 2024 to 0:30 on the same day is flat (STEP 28).

[0082] In this example, the first value is 4600 mmHg / day and the second value is 4300 mmHg / day, so the first comparison value is −300. In other words, the first comparison value is equal to or greater than −500 and less than +500, so the control unit 23 generates first change trend information indicating that the change trend of the mean blood pressure from the first period to the second period is flat (STEP 29).

[0083] In this example, the second value is 4300 mmHg / day and the third value is 3850 mmHg / day, so the second comparison value is −450. In other words, the second comparison value is greater than or equal to −500 and less than +500, so the control unit 23 generates second change trend information indicating that the change trend of the mean blood pressure from the second period to the third period is flat (STEP 30).

[0084] Next, STEP 31 will be described. The control unit 23 determines whether various information, such as change trend information, has been generated for all types of biometric information input to the input interface 21 (STEP 31). If the control unit 23 determines that various information has been generated for all types of biometric information input to the input interface 21 (YES in STEP 31), it executes STEP 32. On the other hand, if the control unit 23 determines that there is biometric information input to the input interface 21 for which various information has not been generated (NO in STEP 31), it executes STEP 25 again for the biometric information for which various information has not been generated. In this embodiment, once the control unit 23 has generated various information, such as change trend information regarding heart rate and mean blood pressure, it determines that various information has been generated for all types of biometric information input to the input interface 21 (YES in STEP 31), and executes STEP 32.

[0085] STEP 32 to STEP 34 are the same as STEP 11 to STEP 13 in the first example of the first embodiment, except that in this example, an image 200 shown in FIG.

[0086] Here, an image 200 based on the display data displayed on the display unit 24 will be described with reference to Fig. 5. As illustrated in Fig. 5, the image 200 includes a first name M1, a second name M2, a first axis AX1, a second axis AX2, a third axis AX3, a fourth axis AX4, a heart rate graph object G1, a mean blood pressure graph object G2, a first graphic D1, a second graphic D2, a third graphic D3, a fourth graphic D4, a fifth graphic D5, and a sixth graphic D6.

[0087] The second name M2 is based on name information related to mean blood pressure. Therefore, in this embodiment, the second name M2 is mean blood pressure. The second name M2 is displayed in the center left of the display unit 24. The third axis AX3 is the time axis and extends horizontally (left and right in FIG. 5). The fourth axis AX4 indicates values ​​related to mean blood pressure and extends vertically (up and down in FIG. 5).

[0088] The mean blood pressure graph object G2 corresponds to biological information related to mean blood pressure. The mean blood pressure graph object G2 indicates the magnitude of each mean blood pressure. The mean blood pressure graph object G2 is displayed in a second region R2 defined by a third axis AX3 and a fourth axis AX4. In a left region R21 located on the left side of the second region R2, a graph object corresponding to biological information related to mean blood pressure on March 2, 2024 from the mean blood pressure graph object G2 is displayed. In a central region R22 located in the center of the second region R2, a graph object corresponding to biological information related to mean blood pressure on March 3, 2024 from the mean blood pressure graph object G2 is displayed. In a right region R23 located on the right side of the second region R2, a graph object corresponding to biological information related to mean blood pressure on March 4, 2024 from the mean blood pressure graph object G2 is displayed.

[0089] The fourth figure D4 corresponds to the initial change trend information related to mean blood pressure. The fifth figure D5 corresponds to the first change trend information related to mean blood pressure. The sixth figure D6 corresponds to the second change trend information related to mean blood pressure. The fourth figure D4, the fifth figure D5, and the sixth figure D6 are displayed in the center right of the display unit 24. However, the display positions of the fourth figure D4, the fifth figure D5, and the sixth figure D6 are not limited to this example. For example, the fourth figure D4, the fifth figure D5, and the sixth figure D6 may be displayed in the center left or the upper right of the display unit 24. The fourth figure D4, the fifth figure D5, and the sixth figure D6 are displayed side by side, and the arrangement order of the fourth figure D4, the fifth figure D5, and the sixth figure D6 indicates the chronological order. In other words, multiple pieces of change trend information related to mean blood pressure in the display data are displayed side by side, and the arrangement order of the multiple pieces of change trend information related to mean blood pressure indicates the chronological order of the change trend information related to mean blood pressure.

[0090] The fourth, fifth, and sixth figures D4, D5, and D6 are inclined. The fourth, fifth, and sixth figures D4, D5, and D6 are displayed as arrows. The initial change trend information for mean blood pressure indicates that the change trend of the subject's mean blood pressure from 0:00 to 0:30 on March 2, 2024 is flat, so the slope of the fourth figure D4 is zero. The first change trend information for mean blood pressure indicates that the subject's mean blood pressure from March 2, 2024 to March 3, 2024 is flat, so the slope of the fifth figure D5 is zero. The second change trend information for mean blood pressure indicates that the change trend of the subject's mean blood pressure from March 3, 2024 to March 4, 2024 is flat, so the slope of the sixth figure D6 is zero.

[0091] In this embodiment, the display modes of the fourth, fifth, and sixth figures D4, D5, and D6 (the shade of the color applied to the fourth, fifth, and sixth figures D4, D5, and D6) are determined based on the condition information related to the mean blood pressure. In this embodiment, the condition information related to the mean blood pressure on March 2, 2024, March 3, 2024, and March 4, 2024 indicates that the subject's condition is good. Therefore, the fourth, fifth, and sixth figures D4, D5, and D6 are colored light red. Note that in FIG. 5, the shade of the color is represented by the number of hatched lines. In this way, the display modes of the fourth, fifth, and sixth figures D4, D5, and D6 are determined based on the biological information and reference information related to the mean blood pressure.

[0092] By viewing image 200, the user can understand that the subject's heart rate is gradually increasing while the mean blood pressure is not fluctuating significantly. In addition, since it is known that the mean blood pressure gradually decreases in such cases, by viewing image 200, the user can also predict that the subject's mean blood pressure will gradually decrease in the future.

[0093] In this example, the information processing device 20 also provides the same effects as the first example of the first embodiment.

[0094] Furthermore, according to the information processing device 20 having the above configuration, in the display data, a plurality of pieces of change trend information generated for each piece of biometric information based on two types of biometric information are displayed side by side for each piece of biometric information. Therefore, for example, by visually checking the image 200 based on such display data, the user can grasp the change trends for the two types of biometric information, and therefore can accurately grasp the condition of the subject.

[0095] (Third Example of the First Embodiment) Next, a third example of the first embodiment will be described with reference to FIGS. 2 and 6. FIG. 6 is a diagram illustrating an image 300 based on display data. In this example, parts similar to those in the first example of the first embodiment will be described using the same reference numerals, and descriptions of overlapping parts will be omitted as appropriate. This example differs from the first example of the first embodiment in that display data is generated in a form in which a first biometric information group, a second biometric information group, and a third biometric information group are displayed, with a first axis AX10, which is the time axis, overlapping and a second axis AX20, which indicates values ​​related to biometric information, being shared. In this example, the biometric information is heart rate. Therefore, unless otherwise specified, in this example, "biometric information," "first biometric information group," "second biometric information group," and "third biometric information group" refer to heart rate.

[0096] In this embodiment, the display data includes a first graph object G10 (see Figure 6) indicating the size of each piece of biometric information included in the first biometric information group, a second graph object G20 (see Figure 6) indicating the size of each piece of biometric information included in the second biometric information group, and a third graph object G30 (see Figure 6) indicating the size of each piece of biometric information included in the third biometric information group.

[0097] In this embodiment, the control unit 23 identifies a first portion P1 (see FIG. 6) surrounded by the first graph object G10 and the first axis AX10. The control unit 23 identifies a second portion P2 (see FIG. 6) surrounded by the second graph object G20 and the first axis AX10. The control unit 23 identifies a third portion P3 (see FIG. 6) surrounded by the third graph object G30 and the first axis AX10. The control unit 23 identifies an overlapping portion P110 (see FIG. 6) where the first portion P1 and the second portion P1 overlap. The control unit 23 identifies an overlapping portion P120 (see FIG. 6) where the first portion P1 and the third portion P3 overlap. The control unit 23 identifies an overlapping portion P130 (see FIG. 6) where the second portion P2 and the third portion P3 overlap. The control unit 23 identifies an overlapping portion P140 (see FIG. 6) where the first portion P1, the second portion P2, and the third portion P3 overlap. The control unit 23 identifies non-overlapping portions P200, P300, and P400 (see FIG. 6) that are portions where at least two of the first portion P1, the second portion P2, and the third portion P3 do not overlap (i.e., portions other than overlapping portions P110, P120, P130, and P140). Note that the non-overlapping portion P200 is a portion of the first portion P1, the non-overlapping portion P300 is a portion of the second portion P2, and the non-overlapping portion P400 is a portion of the third portion P3.

[0098] The control unit 23 adjusts the RGB gradations to set the colors to be applied to the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400, respectively. RGB stands for the three primary colors of light, where R represents red, G represents green, and B represents blue. In this embodiment, the non-overlapping portion P200 is colored a first color (blue), the non-overlapping portion P300 is colored a second color (red), and the non-overlapping portion P400 is colored a third color (green). The control unit 23 also sets the average value of the gradations of each of the RGB colors in the first color and the second color as the gradations of each of the RGB colors in the fourth color to be applied to the overlapping portion P110. Therefore, the fourth color is a color that combines blue and red (i.e., purple). The control unit 23 determines the average value of the gradation of each RGB color in the first color and the gradation of each RGB color in the third color as the gradation of each RGB color in the fifth color to be colored in the overlapping portion P120. Therefore, the fifth color is a color that combines blue and green (i.e., blue-green). The control unit 23 determines the average value of the gradation of each RGB color in the second color and the gradation of each RGB color in the third color as the gradation of each RGB color in the sixth color to be colored in the overlapping portion P130. Therefore, the sixth color is a color that combines red and green (i.e., yellow). The control unit 23 determines the average value of the gradation of each RGB color in the first color, the gradation of each RGB color in the second color, and the gradation of each RGB color in the third color as the gradation of each RGB color in the seventh color to be colored in the overlapping portion P140. Therefore, the seventh color is a color that combines blue, red, and green (i.e., gray).

[0099] In this embodiment, the control unit 23 executes the information processing method illustrated in Fig. 2. However, in this embodiment, the control unit 23 generates graph object information based on a first biometric information group, graph object information based on a second biometric information group, and graph object information based on a third biometric information group. The control unit 23 also generates display data in a format in which the first biometric information group, the second biometric information group, and the third biometric information group are displayed in a state in which the first axis AX10, which is the time axis, overlaps and the second axis AX20, which indicates values ​​related to the biometric information, is common. Therefore, in this embodiment, the display unit 24 displays an image 300 illustrated in Fig. 6.

[0100] As illustrated in FIG. 6, the image 300 includes a first name M1, a first axis AX10, a second axis AX20, a first graph object G10, a second graph object G20, a third graph object G30, a first graphic D1, a second graphic D2, and a third graphic D3. The first axis AX10 extends horizontally (left-right in FIG. 6). The second axis AX20 extends vertically (up-down in FIG. 6). The first graph object G10, the second graph object G20, and the third graph object G30 indicate the magnitude of each heart rate. The first graph object G10 corresponds to a first biometric information group. The second graph object G20 corresponds to a second biometric information group. The third graph object G30 corresponds to a third biometric information group. In this embodiment, the first biometric information group, the second biometric information group, and the third biometric information group are displayed in a state in which the first displayable area R10 in which the first biometric information group can be displayed, the second displayable area R20 in which the second biometric information group can be displayed, and the third displayable area R30 in which the third biometric information group can be displayed overlap on the same time axis (i.e., on the first axis AX10).

[0101] In this embodiment, the non-overlapping portion P200 is colored blue, the non-overlapping portion P300 is colored red, and the non-overlapping portion P400 is colored green. The overlapping portion P110 is colored purple, the overlapping portion P120 is colored cyan, the overlapping portion P130 is colored yellow, and the overlapping portion P140 is colored gray. In FIG. 6 , the hatched portions indicated by diagonal lines slanting downward to the right indicate the portions colored blue. The hatched portions indicated by vertical lines indicate the portions colored red. The hatched portions indicated by dots indicate the portions colored green. The hatched portions indicated by diagonal lines slanting upward to the right indicate the portions colored purple. The hatched portions indicated by vertical lines consisting of thin and thick lines indicate the portions colored cyan. The hatched portions indicated by horizontal lines consisting of thin and thick lines indicate the portions colored yellow. The horizontally hatched portions indicate grayed-out portions. Thus, the display manner of the overlapping portions P110, P120, P130, and P140 differs from the display manner of the non-overlapping portions P200, P300, and P400 (portions including only the first portion P11, the second portion P12, or the third portion P13). This allows the user to easily distinguish between the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400. Furthermore, the overlapping portions P110, P120, P130, and P140 are colored in the colors associated with two or more overlapping portions among the first portion P1, the second portion P2, and the third portion P3. This allows the user to intuitively recognize that the overlapping portions P110, P120, P130, and P140 are portions where at least two of the first portion P1, the second portion P2, and the third portion P3 overlap.

[0102] The average value of the values ​​indicated by the biometric information included in the third biometric information group (heart rate in this embodiment) is displayed in the lower center of the image 300. In this embodiment, the number "109" indicating the average value is displayed in the lower center of the image 300. The location where the average value of the values ​​indicated by the biometric information included in the third biometric information group is displayed in the image 300 is not limited to the lower center of the image 300. The value displayed in the lower center of the image 300 may also be, for example, the value indicated by the biometric information at any time during the third period.

[0103] In this example, the information processing device 20 also provides the same effects as the first example of the first embodiment.

[0104] Furthermore, according to the information processing device 20 having the above configuration, the display data includes a first axis AX10, which is a time axis, and a second axis AX20, which indicates the magnitude of the value of the subject's biometric information. The display data is generated in a format in which the first biometric information group, the second biometric information group, and the third biometric information group are displayed with the first axes AX10 overlapping and the second axis AX20 being common. Therefore, by visually viewing the image 300 based on such display data, the user can easily notice the difference between the first biometric information group and the second biometric information group, or the difference between the second biometric information group and the third biometric information group.

[0105] Furthermore, according to the information processing device 20 having the above configuration, the first graph object G10, the second graph object G20, the third graph object G30, the first figure D1, the second figure D2, and the third figure D3 are displayed on the same screen (within the image 300). Therefore, by visually checking the image 300, the user can quickly recognize the change trends in the subject's biological information within each period, the difference between each period, and the change trends in the subject's biological information when comparing the previous and next periods.

[0106] (Fourth Example of the First Embodiment) Next, a fourth example of the first embodiment will be described with reference to FIGS. 4 and 7. FIG. 7 is a diagram illustrating an image 400 based on display data. In this example, parts similar to those in the first to third examples of the first embodiment will be described using the same reference numerals, and descriptions of overlapping parts will be omitted as appropriate. This example differs from the second example of the first embodiment in that display data is generated in a format in which a first biological information group, a second biological information group, and a third biological information group related to heart rate are displayed, with a first axis AX10, which is the time axis, overlapping and a second axis AX20, which indicates values ​​related to biological information, being shared. In this example, the control unit 23 also performs information processing similar to that in the third example of the first embodiment.

[0107] In this embodiment, the control unit 23 executes the information processing method illustrated in Fig. 4. However, in this embodiment, the control unit 23 generates display data including a first biological information group related to heart rates, a second biological information group related to heart rates, and a third biological information group related to heart rates. The control unit 23 also generates the display data in a format in which the first biological information group, the second biological information group, and the third biological information group related to heart rates are displayed with the first axis AX10 overlapping and the second axis AX20 being common. Therefore, in this embodiment, the display unit 24 displays an image 400 illustrated in Fig. 7.

[0108] As shown in Fig. 7, image 400 differs from image 300 in that it includes arrow-shaped figures (fourth figure D4, fifth figure D5, and sixth figure D6) that indicate the change trend of mean blood pressure. Note that fourth figure D4 is displayed directly below first figure D1. Fifth figure D5 is displayed directly below second figure D2. Sixth figure D6 is displayed directly below third figure D3.

[0109] In this example as well, the information processing device 20 provides the same effects as those of the first to third examples of the first embodiment.

[0110] Furthermore, according to the information processing device 20 having the above configuration, the image 400 includes a first graph object G10, a second graph object G20, a third graph object G30, a first graphic D1, a second graphic D2, a third graphic D3, a fourth graphic D4, a fifth graphic D5, and a sixth graphic D6. That is, the image 400 also includes an arrow-shaped graphic indicating a change trend in biological information (mean blood pressure) different from the biological information (heart rate) displayed in the first graph object G10, the second graph object G20, and the third graph object G30. In this way, by displaying the graph object related to mean blood pressure on the display unit 24 along with the graph object related to heart rate and the arrow-shaped graphic, it is possible to prevent an increase in the number of displayed graph objects, which would reduce visibility, and also enable the user to accurately grasp the subject's condition.

[0111] Second Embodiment Next, an information processing system 1A according to a second embodiment will be described with reference to Fig. 8. In this embodiment, parts that are the same as those in the first embodiment will be described using the same reference numerals as in the first embodiment, and descriptions of overlapping parts will be omitted as appropriate. This embodiment differs from the first embodiment in that the information processing system 1A includes an information processing device 20A instead of the information processing device 20, and also includes a server 30 and a terminal device 40.

[0112] FIG. 8 is a schematic diagram of an information processing system 1A according to a second embodiment. The information processing system 1A is used, for example, in a medical facility such as a hospital. As illustrated in FIG. 8, the information processing system 1A includes a sensor 10, an information processing device 20A, a server 30, and a terminal device 40. The sensor 10 and the information processing device 20A are connected via a wired or wireless connection. The information processing device 20A, the server 30, and the terminal device 40 are communicatively connected via a network N. The network N is, for example, a computer network such as a cloud network. A cloud network is a computer network that exists within a cloud computing infrastructure.

[0113] The information processing device 20A includes an input interface 21, a control unit 23, an operation unit 26, and an output interface 27. These are connected to each other so as to be able to communicate with each other via a bus 25. In this embodiment, the control unit 23 transmits display data and the like to the output interface 27.

[0114] The operation unit 26 is configured to accept input operations by a user such as a medical professional. The operation unit 26 is, for example, a touch panel superimposed on the display unit 24, operation buttons attached to the housing, etc. For example, when a user performs an input operation on the operation unit 26 to acquire desired information from the server 30, the operation unit 26 generates a request signal to acquire the desired information from the server 30 based on the input operation. The operation unit 26 transmits the generated request signal to the server 30.

[0115] The output interface 27 outputs the display data etc. received from the control unit 23 to the terminal device 40. For example, the output interface 27 outputs an output signal corresponding to the display data etc. to the terminal device 40. The output interface 27 may include a circuit for converting the output data into an output signal that can be processed by the terminal device 40, as necessary.

[0116] The server 30 is, for example, a server computer that exists on a cloud network. The server 30 includes a storage unit 31 and a control unit 32.

[0117] The storage unit 31 may have the same hardware configuration as the storage unit 22 of the information processing device 20. The storage unit 31 stores, for example, various types of information similar to the various types of information stored in the storage unit 22 in the first embodiment.

[0118] The control unit 32 may have the same hardware configuration as the control unit 23. The control unit 32 transmits all or part of the various information stored in the storage unit 31 to the information processing device 20A, for example, based on a request signal transmitted from the operation unit 26 of the information processing device 20A.

[0119] The terminal device 40 is, for example, an electronic device such as a desktop PC, a notebook PC, a tablet terminal, a smartphone, etc. The terminal device 40 includes a display unit 41.

[0120] The display unit 41 is, for example, a touch screen display such as a liquid crystal display, an organic EL display, etc. The display unit 41 displays, for example, display data received from the information processing device 20A.

[0121] In this embodiment, the information processing device 20A executes the information processing method exemplified in Fig. 2 or 4. However, the control unit 23 of the information processing device 20A transmits the generated display data to the output interface 27. Then, the output interface 27 outputs the display data received from the control unit 23 to the terminal device 40. Therefore, in this embodiment, images 100, 200, 300, and 400 are displayed on the display unit 41 of the terminal device 40.

[0122] The information processing device 20A having the above configuration also provides the same effects as the information processing device 20 according to the first embodiment.

[0123] The above-described embodiments are provided to facilitate understanding of the present disclosure, and are not intended to limit the present disclosure, which may be modified or improved without departing from the spirit and scope of the present disclosure.

[0124] In the above embodiment, the display data includes biometric information (including the first, second, and third biometric information groups) and name information, but the display data does not need to include at least one of the biometric information and name information. For example, in a first example of the first embodiment, if the display data does not include biometric information, an image 500 shown in FIG. 9 is displayed on the display unit 24 of the information processing device 20.

[0125] In the above embodiment, the control unit 23 generates display data in which multiple pieces of change trend information are displayed side by side, but may also generate display data in which multiple pieces of change trend information are displayed overlapping each other. For example, in the first example of the first embodiment, when the control unit 23 generates display data in which multiple pieces of change trend information are displayed overlapping each other, an image 600 shown in Fig. 10 is displayed on the display unit 24 of the information processing device 20. In this case, the sizes of the arrow-shaped figures may be different, as shown in Fig. 10.

[0126] In the above embodiment, the first value is the sum of the values ​​indicated by each piece of biometric information included in the first biometric information group, the second value is the sum of the values ​​indicated by each piece of biometric information included in the second biometric information group, and the third value is the sum of the values ​​indicated by each piece of biometric information included in the third biometric information group. However, the first value, second value, and third value are not limited to this example. For example, the first value may be the average value of values ​​obtained by performing a moving average process on the first biometric information group, the second value may be the average value of values ​​obtained by performing a moving average process on the second biometric information group, and the third value may be the average value of values ​​obtained by performing a moving average process on the third biometric information group. In this case, the information processing device 20, 20A can generate the first change trend information and the second change trend information through relatively simple information processing.

[0127] In the above embodiment, the control unit 23 classifies the biometric information input to the input interface 21 into a first biometric information group, a second biometric information group, and a third biometric information group, but the present disclosure is not limited to this. For example, the control unit 23 may classify the biometric information input to the input interface 21 into a first biometric information group, a second biometric information group, a third biometric information group, and a fourth biometric information group. In other words, the control unit 23 may classify the biometric information input to the input interface 21 into four or more biometric information groups.

[0128] In the second embodiment, the information processing system 1A includes the sensor 10, the information processing device 20A, the server 30, and the terminal device 40, but may include a central monitor instead of the server 30. In this case, the central monitor has the same functions as the server 30.

[0129] In the third and fourth examples of the first embodiment, the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400 are colored differently, but the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400 do not have to be colored. In this case, the first graph object G10, the second graph object G20, and the third graph object G30 may be displayed in different ways. For example, the first graph object G10 may be a solid-line graph, the second graph object G20 may be a dashed-line graph, and the third graph object G30 may be a dashed-dotted-line graph.

[0130] In the above embodiment, the initial change trend information is generated based on a value obtained by subtracting the value indicated by the biometric information input into the input interface 21 at the input start time from the value indicated by the biometric information input into the input interface 21 a predetermined time after the input start time (one hour in the above embodiment), but the present disclosure is not limited to this. For example, the initial change trend information may be generated based on a value obtained by dividing the value indicated by the biometric information input into the input interface 21 a predetermined time after the input start time by the value indicated by the biometric information input into the input interface 21 at the input start time.

[0131] In the above embodiment, the first comparison value is the difference between the first value and the second value (the value obtained by subtracting the first value from the second value), and the second comparison value is the difference between the second value and the third value (the value obtained by subtracting the second value from the third value), but the present disclosure is not limited to this. For example, the first comparison value may be the value obtained by dividing the second value by the first value, and the second comparison value may be the value obtained by dividing the third value by the second value. For example, the first comparison value may be the value obtained by subtracting the average value (first average value) of the values ​​indicated by each piece of biometric information included in the first biometric information group from the average value (second average value) of the values ​​indicated by each piece of biometric information included in the third biometric information group from the second average value. For example, the first comparison value may be the value obtained by dividing the second average value by the first average value, and the second comparison value may be the value obtained by dividing the third average value by the second average value. For example, the first comparison value may be a value obtained by subtracting the median (first median) of values ​​indicated by each piece of biometric information included in the first biometric information group from the median (second median) of values ​​indicated by each piece of biometric information included in the second biometric information group, and the second comparison value may be a value obtained by subtracting the second median from the median (third median) of values ​​indicated by each piece of biometric information included in the third biometric information group. For example, the first comparison value may be a value obtained by dividing the second median by the first median, and the second comparison value may be a value obtained by dividing the third median by the second median. For example, the first comparison value may be the largest difference (maximum difference) among the differences between the values ​​indicated by the biometric information at each time in the first biometric information group and the second biometric information group, and the second comparison value may be the largest difference (maximum difference) among the differences between the values ​​indicated by the biometric information at each time in the second biometric information group and the third biometric information group.

[0132] In the above embodiment, biometric information for the period from 0:00 on March 2, 2024 to 23:59 on March 4, 2024 is input to the input interface 21, but the present disclosure is not limited to this. For example, biometric information for the period from 0:00 on March 2, 2024 to 23:59 on March 5, 2024 may be input to the input interface 21. In this case, the control unit 23 classifies the biometric information for the period from 0:00 on March 3, 2024 to 23:59 on March 5, 2024 into a first biometric information group including the biometric information on March 3, 2024, a second biometric information group including the biometric information on March 4, 2024, and a third biometric information group including the biometric information on March 5, 2024. In this case, the control unit 23 generates multiple pieces of change trend information for the most recent three days from the day to which the current time belongs.

[0133] In the above embodiment, the control unit 23 generates the condition information based on whether the number of biological information values ​​showing values ​​outside the normal range in a given day is equal to or greater than a predetermined value, but the present disclosure is not limited to this. For example, the control unit 23 may generate the condition information based on whether the first value, the second value, or the third value is equal to or greater than a predetermined value.

[0134] In the above embodiment, when the condition information indicates that the subject's condition is good, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information is colored light red, whereas when the condition information indicates that the subject's condition is poor, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information is colored dark red. However, the present disclosure is not limited to this. For example, when the condition information indicates that the subject's condition is good, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information may be colored blue, whereas when the condition information indicates that the subject's condition is poor, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information may be colored red. Also, for example, when the condition information indicates that the subject's condition is good, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information may be displayed in a first pattern, whereas when the condition information indicates that the subject's condition is poor, the arrow-shaped graphic corresponding to the change trend information for the period corresponding to the condition information may be displayed in a second pattern.

[0135] In the above embodiment, the display positions of the first graphic D1, the second graphic D2, the third graphic D3, the fourth graphic D4, the fifth graphic D5, and the sixth graphic D6 are not limited to those described in the above embodiment. For example, the first graphic D1, the second graphic D2, the third graphic D3, the fourth graphic D4, the fifth graphic D5, and the sixth graphic D6 may be displayed directly above the heart rate graph object G1, the mean blood pressure graph object G2, the first graph object G10, the second graph object G20, and the third graph object G30. For example, when such a display is performed in the first example of the first embodiment, an image 700 shown in FIG. 11 is displayed on the display unit 24 of the information processing device 20. As shown in FIG. 11, in the image 700, the first graphic D1 is displayed directly above the graph object corresponding to the biometric information related to the heart rate on March 2, 2024, in the heart rate graph object G1. The second graphic D2 is displayed directly above the graph object of the heart rate graph object G1 that corresponds to the biometric information related to the heart rate on March 3, 2024. The third graphic D3 is displayed directly above the graph object of the heart rate graph object G1 that corresponds to the biometric information related to the heart rate on March 4, 2024. That is, in this case, the first graphic D1 is displayed in the left region R11, the second graphic D2 in the center region R12, and the third graphic D3 in the right region R13.

[0136] In the above embodiment, the display data includes biometric information (including the first, second, and third biometric information groups), and the images 100, 200, 300, and 400 include graph objects corresponding to the biometric information. However, the present disclosure is not limited to this. For example, the display data may include biometric waveform information instead of biometric information, and the images 100, 200, 300, and 400 may include biometric waveform graph objects corresponding to the biometric waveform information. In this case, the control unit 23 generates the biometric waveform information based on the biometric information input to the input interface 21. The control unit 23 then generates display data including the biometric waveform information. For example, in the first example of the first embodiment, if the display data includes biometric waveform information instead of biometric information, an image 800 as shown in FIG. 12 is displayed on the display unit 24 of the information processing device 20. As shown in FIG. 12, the image 800 includes a biometric waveform graph object G3 indicating, for example, biometric waveform information for the last minute before the current time. Above the biological waveform graph object G3, a first graphic D1, a second graphic D2, and a third graphic D3 are displayed.

[0137] In the above embodiment, an image 900 may be displayed on the display unit 24 of the information processing device 20, as exemplified in Fig. 13. In addition to the first figure D1, the second figure D2, and the third figure D3 included in the image 800 shown in Fig. 12, the image 900 also displays a fourth figure D4, a fifth figure D5, and a sixth figure D6 as change trend information. The fourth figure D4, the fifth figure D5, and the sixth figure D6 are figures with a slope, and the slope indicates the change trend of the biometric information from one period to another.

[0138] For example, as described above, the 24 hours immediately preceding the current time is the third period, the 24 hours immediately preceding the third period is the second period, and the 24 hours immediately preceding the second period is the first period. Also, the 6 hours immediately preceding the current time is the sixth period, the 6 hours immediately preceding the sixth period is the fifth period, and the 6 hours immediately preceding the fifth period is the fourth period.

[0139] In this case, in the image 900, for example, initial change trend information is displayed by a first graphic D1, similar to the image 100 shown in Fig. 3. Furthermore, for example, first change trend information based on the difference between a first value obtained by performing a moving average process on a first biological information group obtained in a first period and a second value obtained by performing a moving average process on a second biological information group obtained in a second period is displayed by a second graphic D2. Furthermore, for example, second change trend information based on the difference between the second value and a third value obtained by performing a moving average process on a third biological information group obtained in a third period is displayed by a third graphic D3.

[0140] Furthermore, for example, a fourth graphic D4 displays third change trend information based on the difference between a fourth value obtained by performing a moving average process on a fourth biometric information group obtained in a fourth period and a fifth value obtained by performing a moving average process on a fifth biometric information group obtained in a fifth period. Furthermore, for example, a fifth graphic D5 displays fourth change trend information based on the difference between the fourth value and a fifth value obtained by performing a moving average process on a fifth biometric information group obtained in a fifth period. Furthermore, a sixth graphic D6 displays fifth change trend information based on the difference between the fifth value and a sixth value obtained by performing a moving average process on a sixth biometric information group obtained in a sixth period.

[0141] In the example shown in FIG. 13, the first, second, and third periods are 24 hours long, while the fourth, fifth, and sixth periods are 6 hours long. Thus, the lengths of the periods corresponding to the plurality of pieces of change trend information may be different from one another. Furthermore, as described above, the biowaveform graph object G3 indicates biowaveform information for the last minute before the current time. Thus, the length of the period corresponding to the change trend information (24 hours or 6 hours in the example shown in FIG. 13) may be different from the length of the period corresponding to the graph object displayed in the image 900 (1 minute in the example shown in FIG. 13).

[0142] 13, the 24 hours (third period) immediately preceding the current time includes the six hours (sixth period) immediately preceding the current time, the six hours (fifth period) immediately preceding the sixth period, and the six hours (fourth period) immediately preceding the fifth period. In this way, at least some of the periods corresponding to the plurality of pieces of change trend information may overlap.

[0143] Furthermore, the period corresponding to each piece of change trend information may be displayed in a recognizable manner. For example, in the example shown in Fig. 13, the word "initial" is displayed near the first graphic D1, indicating that the information is initial change trend information. Furthermore, the word "24 hours" is displayed near the second graphic D2 and the third graphic D3, indicating that the length of the corresponding period is 24 hours. Furthermore, the word "2 days ago" is displayed near the second graphic D2, indicating that the corresponding period (second period) is two days ago. Furthermore, the word "1 day ago" is displayed near the third graphic D3, indicating that the corresponding period (third period) is one day ago.

[0144] Further, the word "6 hours" is displayed near the fourth graphic D4, the fifth graphic D5, and the sixth graphic D6, indicating that the length of the corresponding period is 6 hours. Note that the change trend information of the first graphic D1, the second graphic D2, the third graphic D3, etc. shown in Figures 3, 5, 6, etc. may also be similarly displayed so that the corresponding period can be recognized.

[0145] Also, in the image 900 shown in FIG. 13, as an example, three figures (fourth figure D4, fifth figure D5 and sixth figure D6) are displayed, each representing a period of six hours in length, but the number of these figures is not limited to three.

[0146] In addition, in image 900, as an example, fourth, fifth, and sixth figures D4, D5, and D6, which are smaller than third figure D3, are displayed side by side below third figure D3, but this configuration is not limiting. For example, each of fourth, fifth, and sixth figures D4, D5, and D6 may be the same size as third figure D3.

[0147] The fourth, fifth, and sixth figures D4, D5, and D6 may be displayed next to the third figure D3 in the horizontal direction. Alternatively, only a portion of the fourth, fifth, and sixth figures D4, D5, and D6, for example, only the sixth figure D6, may be displayed next to the third figure D3 in the horizontal direction.

[0148] In the above embodiment, an image 1000 may be displayed on the display unit 24 of the information processing device 20, as exemplified in Fig. 14. The image 800 shown in Fig. 12 displays change trend information indicating a change trend of biometric information from one period to another. In contrast, the image 1000 shown in Fig. 14 displays change trend information indicating a change trend of biometric information within a certain period.

[0149] Specifically, a seventh graphic D7, an eighth graphic D8, and a ninth graphic D9 are displayed as change trend information in the image 1000. The seventh graphic D7, the eighth graphic D8, and the ninth graphic D9 are sloped graphics, and the slope indicates the change trend of the biometric information over a certain period of time.

[0150] As described above, the six hours immediately preceding the current time are designated the sixth period, the six hours immediately preceding the sixth period are designated the fifth period, and the six hours immediately preceding the fifth period are designated the fourth period. In this case, in image 1000, for example, if the value obtained by subtracting the value indicated by the biometric information at the end time of the fourth period from the value indicated by the biometric information at the start time of the fourth period is +10 or greater, the seventh graphic D7 indicating the change trend of the biometric information for the fourth period is displayed tilted upward in accordance with the value. Also, for example, if the subtracted value is -10 or greater but less than +10, the seventh graphic D7 is displayed with a tilt of zero in accordance with the value. Also, for example, if the subtracted value is less than -10, the seventh graphic D7 is displayed tilted downward in accordance with the value.

[0151] Similarly, for the fifth period, the slope of an eighth figure D8 indicating the trend of change in the biometric information for the fifth period is determined, for example, according to the value obtained by subtracting the value indicated by the biometric information at the end time of the fifth period from the value indicated by the biometric information at the start time of the fifth period. Similarly, for the sixth period, the slope of a ninth figure D98 indicating the trend of change in the biometric information for the sixth period is determined, for example, according to the value obtained by subtracting the value indicated by the biometric information at the end time of the sixth period from the value indicated by the biometric information at the start time of the sixth period.

[0152] 14, the seventh graphic D7 is inclined upward, indicating that the change trend of the biometric information in the sixth period is upward. The eighth graphic D8 has a slope of zero, indicating that the change trend of the biometric information in the fifth period is flat. The ninth graphic D9 is inclined upward, indicating that the change trend of the biometric information in the fourth period is upward.

[0153] In the above embodiment, an image 1100 may be displayed on the display unit 24 of the information processing device 20, as exemplified in Fig. 15. In the image 1100, a tenth figure D10, an eleventh figure D11, and a twelfth figure D12 are displayed as change trend information. The tenth figure D10, the eleventh figure D11, and the twelfth figure D12 are figures with a slope, and the slope indicates the change trend of the biological information over a period of time.

[0154] The seventh, eighth, and ninth figures D7, D8, and D9 shown in Fig. 14 have different periods showing the change trends of biometric information, whereas the tenth, eleventh, and twelfth figures D10, D11, and D12 shown in Fig. 15 have overlapping periods showing the change trends of biometric information.

[0155] In the example shown in Fig. 15, the tenth figure D10 shows the change trend of the biometric information for the last six hours before the current time, the eleventh figure D11 shows the change trend of the biometric information for the last 24 hours before the current time, and the twelfth figure D12 shows the change trend of the biometric information for the last 48 hours before the current time.

[0156] 12 and 13, when the display data includes biometric waveform information, the user can grasp, for example, the long-term change trend of the subject's biometric information as well as the biometric waveform information for a short period, such as the last minute. Furthermore, by viewing images 1000 and 1100 as shown in FIGS. 14 and 15, the user can grasp the change trend of the biometric information for each period. Therefore, by viewing images 800, 900, 1000, and 1100 based on such display data, the user can more accurately grasp the change trend of the subject's biometric information.

[0157] In the second example of the first embodiment and the fourth example of the first embodiment, two types of biometric information (heart rate and mean blood pressure) are input to the input interface 21, but three or more types of biometric information may be input.

[0158] In the third example of the first embodiment and the fourth example of the first embodiment, the control unit 23 adjusts the RGB gradation to set the colors to be used for the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400, respectively, but the present disclosure is not limited to this. For example, the control unit 23 may use an xy chromaticity diagram to set the colors to be used for the overlapping portions P110, P120, P130, and P140 and the non-overlapping portions P200, P300, and P400.

[0159] In a fourth example of the first embodiment, the image 400 may include not only the first name M1 but also the second name M2. Furthermore, the image 400 may include not only the first graph object G10, the second graph object G20, and the third graph object G30 but also a graph object related to mean blood pressure.

[0160] In the second embodiment, the control unit 32 of the server 30 transmits all or part of the various pieces of information stored in the storage unit 31 to the information processing device 20A based on a request signal transmitted from the operation unit 26 of the information processing device 20A, but the present disclosure is not limited to this. For example, the control unit 32 may transmit all or part of the various pieces of information stored in the storage unit 31 based on a request signal transmitted from an operation unit 42 (see the dashed line portion in FIG. 8 ) provided in the terminal device 40. In this case, the operation unit 42 is, for example, a touch panel superimposed on the display unit 41 or operation buttons attached to the housing, and is configured to receive input operations by the user.
