Summary of the Invention

Problems to be Solved by the Invention

[0005] Patent Document 1 uses the value when the user's exercise intensity is maximum in order to calculate the user's endurance. In order to measure the user's maximum exercise intensity, for example, the user needs to walk at a high speed. However, walking at the maximum speed is burdensome for people with weak bodies or the elderly. Also, there are people who have difficulty walking fast. Therefore, there is a need to present an appropriate amount of exercise to the user without imposing a burden on the user.

[0006] Therefore, an object of the present invention is to provide an exercise goal presentation device, an exercise goal presentation method, and an exercise goal presentation program that can derive an appropriate amount of exercise for the user without imposing a burden on the user.

Means for Solving the Problems

[0007] An exercise target presentation device according to one aspect of the present invention comprises: acquisition means for acquiring exercise indicators obtained from a user's continuous actions over a predetermined period of time; derivation means for acquiring target values ​​for exercises performed by the user based on the exercise indicators acquired by the acquisition means; and presentation means for presenting the target values ​​acquired by the derivation means to the user.

[0008] This system calculates exercise metrics from the user's daily routine and presents target exercise values ​​based on these metrics. Therefore, this system can derive target exercise values ​​without burdening the user.

[0009] In the above-described exercise goal presentation device, the exercise index may be the number of steps taken by the user within the predetermined time, and the target value may be the number of steps per unit time. With this configuration, the user can improve their exercise ability without feeling burdened.

[0010] In the above-described exercise goal presentation device, the target value may be the daily walking time when walking continuously at the aforementioned step count. With this configuration, the user can improve their exercise ability without feeling burdened.

[0011] In the above-described exercise target presentation device, the derivation means may determine that the user is frail if the exercise index is below a predetermined standard value and obtain a target value for frail individuals. With this configuration, an appropriate target value can be presented according to the user's exercise ability.

[0012] In the above-described exercise target presentation device, the derivation means may acquire the target value for frail individuals based on the exercise index acquired in a time shorter than the predetermined time. With this configuration, an appropriate target value can be presented according to the user's exercise ability.

[0013] In the above-described exercise target presentation device, the derivation means may, after determining that the user is frail, release the determination that the exercise indicator meets a predetermined standard value. With this configuration, appropriate target values ​​can be presented according to the user's exercise ability.

[0014] In the above-described exercise goal presentation device, the derivation means may gradually increase the target value when the user achieves the update conditions corresponding to the target value. With this configuration, the user can improve their exercise ability without feeling burdened.

[0015] In the above-described exercise goal presentation device, the derivation means may gradually decrease the target value if the user fails to meet the update conditions corresponding to the target value. With this configuration, the user can improve their exercise ability without feeling burdened.

[0016] In the above-described exercise target presentation device, the derivation means may calculate the target value by multiplying the exercise index by a predetermined number. With this configuration, the target value can be easily derived.

[0017] In the above-described exercise target presentation device, the derivation means may calculate the target value by converting the exercise index into METs. With this configuration, the target value can be standardized regardless of the user's continuous daily activities.

[0018] In the above-described exercise target presentation device, the derivation means may acquire the target value based on the exercise index that is above a preset threshold. This allows for the derivation of a more appropriate target value for the user.

[0019] A method for presenting exercise intensity targets according to one aspect of the present invention comprises: a first step of acquiring an exercise index obtained from a user's continuous actions over a predetermined period of time; a second step of acquiring a target value for the exercise performed by the user based on the exercise index acquired in the first step; and a third step of controlling a presentation means to present the target value acquired in the second step to the user.

[0020] The exercise goal presentation program according to one aspect of the present invention causes a computer to function as an acquisition unit that acquires an exercise index obtained from the actions of a user continuously for a predetermined time, a derivation unit that acquires a target value of the exercise performed by the user based on the exercise index acquired by the acquisition unit, and a control unit that controls a presentation unit to present the target value acquired by the derivation unit to the user.

Advantages of the Invention

[0021] According to the present invention, an appropriate amount of exercise for the user can be derived without imposing a burden on the user.

Modes for Carrying Out the Invention

[0023] Embodiments of the present invention will be described below with reference to the drawings. The embodiments described below are merely examples of how the present invention can be implemented, and the present invention is not limited to the specific configurations described below. In implementing the present invention, specific configurations may be adopted as appropriate depending on the embodiment.

[0024] Figure 1 is an external view of the motion target presentation device 10 of this embodiment.

[0025] The exercise goal presentation device 10 of this embodiment is carried by the user on a daily basis and acquires the user's exercise index (hereinafter referred to as "daily exercise level") from the user's continuous daily activities. The exercise goal presentation device 10 then calculates the target value of the exercise to be performed by the user (hereinafter referred to as "exercise intensity target value") based on the acquired daily exercise level.

[0026] A user's daily, continuous activity is, for example, walking for a predetermined period of time each day; there is no need to walk or run fast to calculate the exercise intensity target value. Therefore, users can derive the exercise intensity target value without feeling any burden.

[0027] Furthermore, in methods that derive exercise intensity target values ​​based on the results of exercise consciously performed by the user, such as in test mode, the user may become too conscious of the test and exert too much force, resulting in unnatural results. On the other hand, the exercise target presentation device 10 of this embodiment derives exercise intensity target values ​​based on continuous daily activities, so it can derive exercise intensity target values ​​based on more natural measurement results without making the user conscious of it.

[0028] In this embodiment, the daily exercise level is defined as the number of steps taken by the user within a predetermined time period (hereinafter referred to as "step pitch"). This predetermined time period is a duration considered to be continuous exercise in minutes, such as 1 minute or 3 minutes, and is a value that excludes walking associated with household chores, etc. In this embodiment, the target exercise intensity value is defined as the number of steps per unit time (hereinafter referred to as "target step pitch") and the daily walking time while continuously walking at the target step pitch (hereinafter referred to as "target walking time").

[0029] Furthermore, the daily exercise level and exercise intensity target values ​​are not limited to the number of steps, but may also be other continuous daily activities and indicators that reflect the user's amount of exercise. These indicators may include, for example, activity level or calories burned.

[0030] The exercise goal presentation device 10, for example, has the function of a pedometer, and the main unit 12 is equipped with a monitor 14 and operation buttons 16.

[0031] Monitor 14 displays the user's step count. Monitor 14 also displays the target step pace, which is the number of steps per unit of time. In addition, Monitor 14 displays the degree of achievement of the target walking time. The degree of achievement displayed on Monitor 14 is the cumulative value of the time the user walked faster than the target step pace. For example, the degree of achievement displayed on Monitor 14 is reset at the start of each new day.

[0032] The operation button 16 is used to turn the exercise target presentation device 10 on or off, and to input various setting values.

[0033] Figure 2 is a functional block diagram of the exercise goal presentation device 10 of this embodiment. The exercise goal presentation device 10 includes an acceleration sensor 20, a step count acquisition unit 22, a daily exercise level acquisition unit 24, a target value derivation unit 26, a target value setting unit 28, a goal achievement determination unit 30, a monitor control unit 32, a storage unit 34, and a communication unit 36. Each function performed by the step count acquisition unit 22, daily exercise level acquisition unit 24, target value derivation unit 26, goal achievement determination unit 30, and monitor control unit 32 shown in Figure 2 may be executed by the calculation unit of the exercise goal presentation device 10 when a program is started, for example, or it may be realized by individual hardware such as an ASIC (Application Specific Integrated Circuit).

[0034] The acceleration sensor 20 detects the acceleration generated in the motion target presentation device 10.

[0035] The step count acquisition unit 22 acquires the step count of the user carrying the exercise goal presentation device 10 based on the detection results from the acceleration sensor 20.

[0036] The daily exercise level acquisition unit 24 acquires the daily exercise level, which is determined from the user's daily activities over a predetermined period of time. In the following explanation, the predetermined period will be referred to as the walking data extraction time.

[0037] The target value derivation unit 26 acquires a target value for the exercise performed by the user (hereinafter referred to as the "exercise intensity target value") based on the daily exercise level acquired by the daily exercise level acquisition unit 24.

[0038] The target value derivation unit 26 of this embodiment calculates the target exercise intensity value by multiplying the daily exercise level by a predetermined factor. In this embodiment, the predetermined factor is 1.1, but it is not limited to this. The target value derivation unit 26 may also read a predetermined target exercise intensity value corresponding to the daily exercise level from the storage unit 34.

[0039] Furthermore, the target value derivation unit 26 of this embodiment calculates the target exercise intensity value by converting the daily exercise level into METs (Metabolic equivalents) as an example. That is, the target value derivation unit 26 of this embodiment obtains 1.1 times the daily exercise level converted to METs as the target exercise intensity value.

[0040] Here, METs is a unit of exercise intensity, with resting being set at 1, and it is an index that indicates the intensity of activity compared to resting. For example, walking is considered to be 3 METs. When converting walking to METs, it is calculated based on the number of steps per unit time, the user's height, and basal metabolic rate. Basal metabolic rate is calculated based on physical information such as body size and body composition.

[0041] The user's age, height, weight, and body fat percentage, and other information required by the exercise goal presentation device 10 of this embodiment, may be input by the user via the operation buttons 16. Alternatively, this information may be obtained from other information processing devices or body composition analyzers by transmitting and receiving data via the communication unit 36.

[0042] The target exercise intensity values ​​obtained as METs are converted into exercises that the user will perform and presented to the user in a way that makes it easier for the user to achieve the target exercise intensity values. In this embodiment, the target exercise intensity values ​​are presented as a target step count and a target walking time achieved by continuously walking at the target step count, as described above. The target step count presented to the user may be indicated by sound (buzzer), light (LED), flashing indicator, vibration, etc., to make it easier for the user to perform.

[0043] As in this embodiment, by converting the daily exercise level into METs, the target exercise intensity can be standardized regardless of the user's continuous daily activities. Furthermore, this allows the target value derivation unit 26 to calculate an optimal target exercise intensity that is tailored to the user's physique.

[0044] In this embodiment, the daily exercise level is converted to METs, but this is not limited to this; other indicators besides METs may be used as long as the daily exercise level can be quantified (normalized) regardless of the type of exercise.

[0045] The target value setting unit 28 sets the exercise intensity target value obtained by the target value derivation unit 26 as the user's exercise intensity target value.

[0046] The goal achievement determination unit 30 determines whether the user has achieved the exercise intensity target value set by the target value setting unit 28. Based on the determination result by the goal achievement determination unit 30, the target value derivation unit 26 obtains a new exercise intensity target value.

[0047] The monitor control unit 32 controls the monitor 14 to display the user's step count and the exercise intensity target value acquired and set by the target value derivation unit 26.

[0048] The memory unit 34 is, for example, a non-volatile memory that stores various data and programs used for processing. The various data include information about the user, the user's step count, the user's exercise intensity target value, and data used to obtain the exercise intensity target value.

[0049] The communication unit 36 ​​transmits and receives data to and from a mobile terminal device such as a smartphone owned by the person being measured, or to other information processing devices such as a server.

[0050] Figures 3 and 4 are flowcharts showing the flow of the exercise intensity target value derivation process performed by the exercise target presentation device 10. Note that the values ​​such as steps, METs, and days used in the explanation of the process in Figures 3 and 4 are examples, and other values ​​may be used.

[0051] First, in step S100, the step count acquisition unit 22 acquires the user's step count every minute and stores it in the storage unit 34 as daily walking data.

[0052] In the next step, S102, the daily exercise level acquisition unit 24 converts the number of steps in the daily walking data into METs.

[0053] In the next step, S104, the daily exercise level acquisition unit 24 determines daily walking data with a step count of 20 steps / minute or more, and deletes data with a step count of less than 20 steps / minute from the storage unit 34 in step S106. Note that walking with a step count of less than 20 steps / minute is, for example, walking associated with housework, and such walking is excluded from the acquisition of the exercise intensity target value in this embodiment.

[0054] In other words, 20 steps / minute is the threshold for extracting daily walking data that is considered exercise (hereinafter referred to as the "exercise threshold"). This exercise threshold is pre-set and may vary depending on, for example, the user's age or gender.

[0055] Therefore, the target value derivation unit 26 obtains the target exercise intensity value based on daily walking data that is above the exercise threshold. This allows the target value derivation unit 26 to derive a more appropriate target exercise intensity value for the user.

[0056] In the next step, S108, the daily exercise level acquisition unit 24 extracts daily walking data of continuous walking for 3 minutes or more from the memory unit 34 and stores it in the memory unit 34.

[0057] In the next step, S110, the daily exercise level acquisition unit 24 calculates the median METs (hereinafter referred to as "median METs") every hour from the daily walking data extracted in step S108 and stores it in the memory unit 34.

[0058] In the next step, S112, the target value derivation unit 26 determines whether it is time to switch the target exercise intensity value. If the determination is positive, the process proceeds to step S114. On the other hand, if the determination is negative, steps S100 to S112 are repeated. The timing for switching the target exercise intensity value is, for example, a predetermined time once a week.

[0059] In step S114, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for three minutes or more in the past seven days. If the determination is positive, the process proceeds to step S116; otherwise, the process proceeds to step S118.

[0060] In step S116, the target value derivation unit 26 obtains the exercise intensity target value A. The exercise intensity target value A is calculated, for example, by multiplying the median METs value for the past 7 days by a predetermined value. The predetermined value is, for example, 1.1, and the exercise intensity target value A is calculated to be an exercise intensity slightly higher than the user's usual exercise volume so as not to cause the user to feel burdened by the exercise.

[0061] The exercise intensity target value obtained in step S116 is a value normalized to METs, so it is converted to a target step count per minute so that the user can easily recognize the exercise they are aiming for. The target step count per minute is set by the target value setting unit 28 as the user's exercise intensity target value and displayed on the monitor 14 by the monitor control unit 32.

[0062] The target walking time included in the exercise intensity target is initially set to 10 minutes / day as a default value, and will increase up to a maximum of 30 minutes / day depending on the user's exercise level, as will be explained in detail later.

[0063] Here, step 114, as described above, determines whether the user is healthy or not. In other words, the exercise intensity target value calculated in step S116 is calculated only if the user is determined to be healthy. On the other hand, if the determination in step S114 is negative, the user may be frail. Therefore, from step S118 onward, a determination is made as to whether the user is frail or not.

[0064] In step S118, the target value derivation unit 26 determines whether the average number of steps per day over the past 7 days is 2000 steps / day or more. If the determination is positive, the process proceeds to step S120; otherwise, the process proceeds to step S118.

[0065] In step S120, the target value derivation unit 26 determines that the user is frail. If this frailty determination is made to the user, the system transitions to the frailty determination mode described later, and the exercise intensity target value is acquired.

[0066] Thus, in the exercise intensity target value derivation process of this embodiment, if there is no data showing continuous walking for 3 minutes or more over a certain period, and the average number of steps is 2000 steps / day or more, the user is determined to be frail.

[0067] In step S122, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for three minutes or more within the past month. If the determination is positive, the process proceeds to step S124; otherwise, the process proceeds to step S128.

[0068] In step S124, the target value derivation unit 26 determines whether the median METs for the most recent few days (e.g., 3 to 7 days) in the past month is 3.0 or less. If the determination is positive, the process proceeds to step S120.

[0069] Thus, in the exercise intensity target value derivation process of this embodiment, if the median METs value is 3.0 or less over a certain period, that is, if a user is determined to be walking slowly on a daily basis based on METs, they are determined to be frail.

[0070] On the other hand, if a negative result is obtained in step S124, the process proceeds to step S126. In step S126, assuming that the user is healthy and not frail, the target value derivation unit 26 obtains the exercise intensity target value B. The exercise intensity target value B is set to 1.1 times the median METs value for the most recent few days (e.g., 3 to 7 days) in the past month.

[0071] In step S128, the target value derivation unit 26 determines whether the average number of steps taken over the most recent few days (for example, 3 to 7 days) in the past month is 2000 steps or more. If the determination is positive, the process proceeds to step S120; otherwise, the process proceeds to step S130.

[0072] In step S130, since the exercise intensity target value cannot be obtained from the user's daily step count, a default exercise intensity target value stored in the memory unit 34 is obtained. This default exercise intensity target value is, for example, a step count pitch based on exercise intensity obtained from the average walking speed of adults of the same age and sex as the user.

[0073] The exercise intensity target values ​​obtained in steps S126 and S130 are normalized to METs, and are therefore converted to target step count per minute. The target step count per minute is set by the target value setting unit 28 as the user's exercise intensity target value and displayed on the monitor 14 by the monitor control unit 32.

[0074] Figure 5 is a flowchart showing the flow of the exercise goal achievement determination process. The exercise goal achievement determination process is a process for displaying the user's degree of achievement of the set exercise intensity target value on the monitor 14.

[0075] First, in step S200, the step count acquisition unit 22 acquires the user's step count every minute and stores it in the storage unit 34 as daily walking data.

[0076] In the next step, S202, the daily exercise level acquisition unit 24 converts the number of steps in the daily walking data into METs.

[0077] In the next step S204, the daily exercise level acquisition unit 24 determines the daily walking data with a step count of 20 steps / minute or more, and deletes data with a step count of less than 20 steps / minute from the storage unit 34 in step S206.

[0078] In the next step S208, the daily exercise level acquisition unit 24 extracts daily walking data of continuous walking for 3 minutes or more from the memory unit 34 and stores it in the memory unit 34.

[0079] In the next step, S210, the daily exercise level acquisition unit 24 calculates the median METs value every hour from the daily walking data extracted in step S208 and stores it in the memory unit 34.

[0080] In the next step, S212, the target achievement determination unit 30 counts METs that are equal to or greater than the exercise intensity target value set by the user.

[0081] In the next step, S214, the goal achievement determination unit 30 accumulates the walking time of users who have exceeded the exercise intensity target value (hereinafter referred to as "actual walking time") based on the METs values ​​that have exceeded the exercise intensity target value. The monitor control unit 32 then displays the cumulative result for the day on the monitor 14. This allows the user to recognize the degree to which they have achieved the exercise intensity target value for the day.

[0082] Furthermore, the goal achievement determination unit 30 accumulates the user's actual walking time at predetermined intervals (for example, every 7 days) and stores it in the storage unit 34.

[0083] In the next step, S216, the target value derivation unit 26 determines whether it is time to switch the target exercise intensity value. If the determination is positive, the process proceeds to step S218. On the other hand, if the determination is negative, the process repeats from step S200 to step S216.

[0084] In the next step, S218, the target walking time is updated. If the result in step S216 is positive, the process from step S114 onwards shown in Figure 3 is performed, and the target step count (pitch) is also updated.

[0085] In the next step, S220, the target achievement determination unit 30 resets the cumulative value of the user's actual walking time, and the process returns to step S200.

[0086] Figure 6 is a flowchart showing the flow of the target walking time update process performed in step 218 above. The update process is performed by the target value derivation unit 26.

[0087] First, in step S300, it is determined whether the set target walking time is the default of 10 minutes / day. If the determination is positive, the process proceeds to step S302; otherwise, the process proceeds to step S308.

[0088] In step S302, it is determined whether the actual walking time has been 120 minutes / week or more for two consecutive weeks. If the result is negative, the process moves to step S304; if it is positive, the process moves to step S306. In step S304, the target walking time remains at 10 minutes / day, and in step S306, the target walking time is updated to 20 minutes / day.

[0089] In step S308, it is determined whether the target walking time is 20 minutes / day. If the determination is positive, the process proceeds to step S310; otherwise, the process proceeds to step S316.

[0090] In step S310, it is determined whether the actual walking time has been 120 minutes / week or more for two consecutive weeks. If the result is positive, the process moves to step S312; if negative, the process moves to step S304, and the target walking time is updated to 10 minutes / day.

[0091] In step S312, it is determined whether the actual walking time has been 240 minutes / week or more for two consecutive weeks. If the result is positive, the process moves to step S314. In step S314, the target walking time is updated to 30 minutes / day. On the other hand, if the result in step S312 is negative, the process moves to step S306, and the target walking time remains at 20 minutes / day.

[0092] Step 308 is used to transition to Step S316 if the target walking time is set to 30 minutes / day. In Step S316, it is determined whether the actual walking time has been 240 minutes / week or more for two consecutive weeks. If the determination is positive, the target walking time remains at the upper limit of 30 minutes / day.

[0093] On the other hand, if the result in step S316 is negative, the process moves to step S302 to determine whether the actual walking time has been 120 minutes / week or more for two consecutive weeks. If the result in step S302 is negative, the process moves to step S304 to update the target walking time to 10 minutes / day, and if the result is positive, the process moves to step S306 to update the target walking time to 20 minutes / day.

[0094] In this way, the exercise intensity target value update process increases the exercise intensity target value in stages when the user meets the update conditions corresponding to the exercise intensity target value. On the other hand, if the user does not meet the update conditions corresponding to the exercise intensity target value, the exercise intensity target value is gradually decreased. This allows the user to improve their exercise ability without feeling burdened. The update conditions are those shown in steps S302, S310, S312, and S316, but the update conditions are not limited to the example in Figure 6 and may be other conditions as well.

[0095] Furthermore, in this embodiment, the user's target exercise intensity is set as step count cadence and target walking time. As described above, when the set target walking time is achieved, the target walking time is increased, but the step count cadence is not increased. The reason for this is that, in the case of elderly users, increasing the step count cadence places a greater burden on the user, while increasing the target walking time places a less burden on the user compared to increasing the step count cadence.

[0096] Depending on the user's age or any settings chosen by the user, it is possible to increase the step count without increasing the target walking time, or to increase both the step count and the target walking time.

[0097] Furthermore, in this embodiment, the target step count and target walking time are updated at the same time as the timing for switching the target exercise intensity values. However, this is not limited to this, and the target step count and target walking time may be updated at different times.

[0098] Figures 7 and 8 are flowcharts showing the flow of the frailty determination mode that is performed when the user is determined to be frail in step S120 of Figure 3.

[0099] Steps S400 to S412 in Figure 7 are the same as steps S100 to S112 in the exercise intensity target value derivation process. In the exercise intensity target value derivation process, the walking data extraction time for extracting daily walking data was set to 3 minutes or more. However, in the frailty judgment mode, as shown in step S408, the walking data extraction time is set to 1 minute or more. Thus, in the frailty judgment mode, the exercise intensity used as the standard for obtaining the exercise intensity target value is set to a weaker value compared to that of a healthy person. Then, in the frailty judgment mode, the exercise intensity target value for frail individuals is obtained based on the daily exercise level obtained in a shorter time than the walking data extraction time.

[0100] In step S414 of Figure 8, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for one minute or more in the past seven days. If the determination is positive, the process proceeds to step S416; if negative, the process proceeds to step S422.

[0101] In step S416, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for three minutes or more in the past seven days. If the determination is positive, the process proceeds to step S418; if negative, the process proceeds to step S420.

[0102] In step S418, the user is determined to be healthy, and the target value derivation unit 26 sets the timing for deriving the exercise intensity target value from the next timing for switching the exercise intensity target value, and then proceeds to step S420.

[0103] In step S420, the target value derivation unit 26 obtains the exercise intensity target value A by multiplying the median METs value for the past 7 days by a predetermined value.

[0104] In step S422, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for one minute or more in the past month. If the determination is positive, the process proceeds to step S424; if negative, the process proceeds to step S430.

[0105] In step S424, the target value derivation unit 26 determines whether there have been three or more days of continuous walking for three minutes or more in the past month. If the determination is positive, the process proceeds to step S426; otherwise, the process proceeds to step S428.

[0106] In step S426, the user is determined to be healthy, and the target value derivation unit 26 sets the timing for the next change in the target exercise intensity to perform the exercise intensity target value derivation process, and then proceeds to step S428.

[0107] In step S428, the target value derivation unit 26 obtains the exercise intensity target value B by multiplying the median METs value for the most recent few days (e.g., 3 to 7 days) in the past month by a predetermined value.

[0108] The user who proceeds to step S430 is the user who has been determined to be frail. Therefore, in step S430, the target value derivation unit 26 obtains a default value for frail users as the target exercise intensity value. This default value is a value obtained in advance from the average value of walking pitch of multiple frail users, etc., and is stored in the memory unit 34.

[0109] The exercise intensity target values ​​acquired in steps S420, S428, and S430 are converted into target step counts and cadences. These are then set as the user's exercise intensity target values ​​by the target value setting unit 28 and displayed on the monitor 14 by the monitor control unit 32.

[0110] Thus, in the mode for frail individuals, if the daily exercise level is below a predetermined standard value (conditions of steps S414 and S422), the user is determined to be frail, and a target exercise intensity value for frail individuals is obtained. This ensures that an appropriate target exercise intensity value is presented according to the user's exercise ability.

[0111] Furthermore, in the frailty mode, if the user is determined to be frail but their daily exercise level meets a predetermined standard value (conditions in steps S416 and S424), the determination that the user is frail is removed, and the user is treated as healthy. This allows for the presentation of appropriate exercise intensity target values ​​according to the user's exercise ability. In addition, this makes it possible to correct a misjudgment of the user as frail and reclassify them as healthy.

[0112] Furthermore, when a user sets an exercise intensity target value for frail individuals, the process for determining whether the exercise target has been achieved is the same as the process explained using Figure 5, but the "extraction and memory of continuous walking for 3 minutes or more" in step S208 is changed to "extraction and memory of continuous walking for 1 minute or more".

[0113] Although the present invention has been described above using the embodiments described above, the technical scope of the present invention is not limited to the scope described in the embodiments above. Various modifications or improvements can be made to the embodiments above without departing from the spirit of the invention, and such modified or improved forms are also included in the technical scope of the present invention.

[0114] In the above embodiment, a method was described in which the user's daily exercise level is normalized to METs to obtain an exercise intensity target value. However, the present invention is not limited to this, and the exercise level may be normalized to an index other than METs to obtain an exercise intensity target value, or the exercise intensity target value may be calculated without normalizing the user's exercise level to an index such as METs.

[0115] In the above embodiment, a method for calculating the target exercise intensity value by multiplying the daily exercise level, which is standardized to METs, by a predetermined value was described. However, the present invention is not limited to this, and the target exercise intensity value corresponding to the daily exercise level may be stored as table data in the storage unit 34. In this embodiment, the target value derivation unit 26 obtains the target exercise intensity value by reading the target exercise intensity value corresponding to the user's daily exercise data from the table data.

[0116] In the above embodiment, a configuration in which the exercise intensity target value is obtained based on step count is described, but the present invention is not limited thereto, and the exercise intensity target value may be obtained using other criteria such as walking speed instead of step count. In the case of using walking speed as the criterion, for example, the exercise target presentation device 10 is equipped with a GPS (Global Positioning System), and the walking speed is calculated based on the measurement results from the GPS.

[0117] Furthermore, the exercise goal presentation device 10 may transmit the user's daily exercise level, target exercise intensity, and degree of achievement of the target exercise intensity to other information processing devices such as a server, allowing the user to check this information on a mobile terminal device or the like.

[0118] Furthermore, the exercise goal presentation device 10 is not a dedicated device; it may also be an application software with the same functions as the exercise goal presentation device 10, which can be installed on a mobile device such as a smartphone owned by the user.

[0119] Furthermore, the exercise goal presentation device 10 is capable of sending and receiving data with other information processing devices such as a server. The exercise goal presentation device 10 may send the daily exercise level it has acquired to the server, and the server may calculate the target exercise intensity value that the user should perform based on the daily exercise level. The exercise goal presentation device 10 then has a target value derivation unit 26 that acquires the target exercise intensity value from the server and displays the target exercise intensity value on the monitor 14.

[0120] Alternatively, the exercise goal presentation device 10 may transmit the user's step count acquired by the exercise goal presentation device 10 to the server, the server may acquire the step count pitch (daily exercise level) from the received step count, and calculate the target exercise intensity value to be performed by the user based on the step count pitch.

[0121] Alternatively, the exercise target presentation device 10 may transmit the acceleration acquired by its acceleration sensor 20 to a server, and the server may acquire the user's step count and step pitch (daily exercise level) from the received acceleration and calculate the target exercise intensity value to be performed by the user based on the step pitch.

[0122] Furthermore, the various algorithms used by the exercise goal presentation device 10 do not necessarily have to be fixed, and various algorithms that are updated as appropriate may be used. For example, they may be modified and updated as appropriate by AI (Artificial Intelligence), etc. For example, the algorithm for calculating the number of steps or step pitch based on the acceleration detected by the acceleration sensor 20 may be modified by AI to improve accuracy. Also, the algorithm for calculating the exercise intensity target value based on the step pitch may be modified to an algorithm more suitable for the user based on the user's achievement status against the exercise intensity target value up to that point. Achievement status refers to whether the time it took to reach the exercise intensity target value was fast or slow, etc.

[0123] The algorithm may be modified by the exercise goal presentation device 10, or by another information processing device such as a server. If the algorithm is modified by the server, the exercise goal presentation device 10 transmits the user's acceleration, step count, and the period for achieving the exercise intensity target value to the server, and the modified algorithm is downloaded from the server to the exercise intensity target presentation device 10.
