Description

Recommended sunbathing time calculation system and program

[0001] The present invention relates to a system and program for calculating recommended sunbathing time.

[0002] Sunbathing generally has a variety of benefits. For example, exposure to sunlight causes the human body to produce vitamin D, which can help maintain the expected level of disease risk reduction and maintain health. Also, exposure to sunlight can reset and maintain biological rhythms, leading to improved sleep quality. Improving sleep quality can improve daily quality of life (QOL) and contribute to daily health maintenance. Specifically, these health maintenance benefits are said to have a positive impact on bones and muscles, and a positive impact on maintaining / improving the immune system (for example, against hay fever, infectious diseases, influenza, etc.). It is also expected to have an effect on temporary depression, etc.

[0003] For example, Patent Documents 1 and 2 disclose inventions that utilize the user's activity in the sun for a period of time longer than that required to reset the circadian rhythm to charge a solar cell worn by the user, and then operate an information processing device using the charged power.

[0005] Sunbathing has many benefits, but it is not necessarily better to sunbathe for a longer period of time. For example, sunbathing for too long can cause sunburn and damage to the skin, which can have adverse effects on the skin. Therefore, it is best to avoid excessive sunbathing and sunbathe for an appropriate amount of time.

[0006] The optimal time for sunbathing also varies depending on the amount of sunlight at the time. When the amount of sunlight is high, the optimal time for sunbathing is shorter, and when the amount of sunlight is low, the optimal time for sunbathing is longer.

[0007] Therefore, the object of the present invention is to solve the above-mentioned problems and provide a recommended sunbathing time calculation system and program that can calculate a recommended guideline sunbathing time based on the amount of sunlight at that time.

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0029] FIG. 1 is a block diagram showing a schematic configuration of a recommended sunbathing time calculation system 1 according to one embodiment of the present invention.

[0030] The recommended sunbathing time calculation system 1 includes a power generation device 10 and an information processing device 20 .

[0031] The power generation device 10 is a portable power generation device that can be carried by a user. The power generation device 10 can generate power by receiving sunlight. The power generation device 10 may be a device that can be held in the user's hand or a device that can be worn by the user. Alternatively, the power generation device 10 may be a device that can be attached to the user's luggage, etc. Alternatively, the power generation device 10 may be incorporated into an information processing device 20, which will be described later.

[0032] The information processing device 20 is a portable information processing device that can be carried by a user. The information processing device 20 may be, for example, a general-purpose information processing device such as a smartphone, a tablet, or a laptop computer. Alternatively, the information processing device 20 may be a dedicated information processing device that can function as the information processing device 20 of the recommended sunbathing time calculation system 1.

[0033] First, the configuration of the power generation device 10 will be described.

[0034] The power generation device 10 includes an energy harvesting unit 11 , a current detection unit 12 , a first control unit 13 , and a first communication unit 14 .

[0035] When receiving sunlight, the energy harvesting unit 11 outputs a generated current according to the amount of solar radiation received. The energy harvesting unit 11 outputs the generated current to the current detection unit 12. The energy harvesting unit 11 is not particularly limited as long as it outputs a generated current according to the amount of solar radiation received. The energy harvesting unit 11 may be, for example, a solar cell, an ultraviolet sensor, an illuminance sensor, or the like.

[0036] The energy harvesting unit 11 may include a solar cell panel composed of solar cells. A solar cell panel is a component including solar cells that photoelectrically convert incident sunlight to output electricity. The types of solar cells included in a solar cell panel can be broadly divided into inorganic solar cells using inorganic materials and organic solar cells using organic materials. Inorganic solar cells include silicon (Si)-based solar cells, compound solar cells using compounds, and quantum dot solar cells using quantum dots. Organic solar cells include thin-film solar cells such as low-molecular-weight deposition solar cells using organic pigments, polymer coating solar cells using conductive polymers, and coating conversion solar cells using conversion semiconductors, as well as dye-sensitized solar cells composed of titania, organic dyes, and electrolytes. Solar cells included in a solar cell panel can also include organic-inorganic hybrid solar cells and solar cells using perovskite-based compounds. Tandem solar cells, which combine or stack these solar cells, are also possible. The solar cell panel may be in the form of a thin panel. In this case, organic thin-film solar cells, dye-sensitized solar cells, or perovskite solar cells fabricated on plastic films or the like are preferred because they are easily molded into thin shapes. It should be noted that when the solar cell panel is in the form of a thin panel, it is not limited to those made of the above-mentioned plastic film, etc., and needless to say, any type may be used as long as it is similarly thin. When the solar cell panel is in the form of a thin panel, its thickness is preferably, for example, 10 μm or more and 3 mm or less from the viewpoint of manufacturing technology.

[0037] The current detection unit 12 detects the generated current supplied from the energy harvesting unit 11. When detecting the generated current, the current detection unit 12 may detect a short-circuit current or may detect a current flowing at an arbitrary point on the IV curve. When detecting the generated current, it is desirable to point the energy harvesting unit 11 toward the sun so that the detected current is maximized.

[0038] The current detection unit 12 outputs the detected generated current to the first control unit 13 .

[0039] The first control unit 13 includes at least one processor, at least one dedicated circuit, or a combination thereof. The processor is a general-purpose processor such as a central processing unit (CPU) or a graphics processing unit (GPU), or a dedicated processor specialized for a specific process. The dedicated circuit is, for example, a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). The first control unit 13 controls each part of the power generation device 10 and executes processes related to the operation of the power generation device 10.

[0040] The first control unit 13 transmits the information on the generated current obtained from the current detection unit 12 to the information processing device 20 via the first communication unit 14 .

[0041] The first communication unit 14 is capable of wireless or wired communication with the second communication unit 21 of the information processing device 20. When performing wireless communication with the second communication unit 21 of the information processing device 20, the first communication unit 14 may include, for example, a communication module compatible with the Bluetooth (registered trademark) communication standard. Alternatively, the first communication unit 14 may include a communication module compatible with a wireless communication standard other than Bluetooth.

[0042] The power generation device 10 may further include an acceleration sensor, a gyro sensor, and the like.

[0043] When the power generation device 10 is equipped with a gyro sensor, the power generation device 10 can automatically determine the positional relationship between the sun and the power generation device 10. Therefore, compared to a method in which a user manually points the power generation device 10 at the sun to measure the amount of solar radiation, as described below, it is possible to measure the amount of solar radiation more easily and accurately.

[0044] Next, the configuration of the information processing device 20 will be described.

[0045] The information processing device 20 includes a second communication unit 21 , a second control unit 22 , an input unit 23 , a display unit 24 , and a storage unit 25 .

[0046] The second communication unit 21 is capable of wireless or wired communication with the first communication unit 14 of the power generation device 10. When performing wireless communication with the first communication unit 14 of the power generation device 10, the second communication unit 21 may include, for example, a communication module compatible with the Bluetooth communication standard. Alternatively, the second communication unit 21 may include a communication module compatible with a wireless communication standard other than Bluetooth.

[0047] The second control unit 22 includes at least one processor, at least one dedicated circuit, or a combination thereof. The processor is a general-purpose processor such as a CPU or GPU, or a dedicated processor specialized for a specific process. The dedicated circuit is, for example, an FPGA or an ASIC. The second control unit 22 controls each unit of the information processing device 20 and executes processes related to the operation of the information processing device 20.

[0048] The second control unit 22 calculates the target sunbathing time and the upper limit sunbathing time based on the information on the generated current acquired from the power generation device 10. Hereinafter, the "target sunbathing time" may be simply referred to as the "target time." Also, the "upper limit sunbathing time" may be simply referred to as the "upper limit time."

[0049] The function of the second control unit 22 will be described in detail later.

[0050] The input unit 23 includes one or more input interfaces that detect user input and acquire input information based on the user's operation. For example, the input unit 23 includes, but is not limited to, physical keys, capacitive keys, a touch screen integrated with the display of the display unit 24, or a microphone that accepts voice input.

[0051] The display unit 24 can display various types of data and may include, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescent) display.

[0052] The storage unit 25 may be, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like, but is not limited to these. The storage unit 25 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 25 stores any information used in the operation of the information processing device 20. For example, the storage unit 25 may store system programs, application programs, various types of information received by the second communication unit 21, and the like.

[0053] Next, the operation of the recommended sunbathing time calculation system 1 will be described.

[0054] The information processing device 20 acquires information about the user of the recommended sunbathing time calculation system 1 as an initial setting.

[0055] Information about the user may include, for example, the user's skin type, the user's goal type, and the like.

[0056] The user's skin type represents the color of the skin. For example, the skin type may be expressed in six levels, such as type 1 to type 6. In this case, for example, the smaller the number, such as type 1, the lighter the skin, and the larger the number, such as type 6, the darker the skin.

[0057] The user's goal type indicates the type of sunbathing goal that the user has in mind, and may be, for example, a health-oriented type, a beauty-oriented type, or a balance-oriented type.

[0058] The health-oriented type is a type that places importance on the expectation of vitamin D production. In other words, the health-oriented type is a type that places importance on producing a lot of vitamin D through sunbathing. When a user selects the health-oriented type, the target sunbathing time is longer than the target sunbathing time when the user selects the beauty-oriented type. Furthermore, when a user selects the health-oriented type, the upper limit sunbathing time may be the same as the upper limit sunbathing time when the user selects the beauty-oriented type, or may be longer than the upper limit sunbathing time when the user selects the beauty-oriented type.

[0059] The beauty-oriented type is a type that emphasizes reducing damage to the skin and reducing the risk of sunburn. In other words, the beauty-oriented type is a type that emphasizes reducing the risk of sunburn and maintaining the quality of the skin as much as possible in its current state, while hoping for the production of vitamin D. When a user selects the beauty-oriented type, the target sunbathing time is shorter than the target sunbathing time when the user selects the health-oriented type. Furthermore, when a user selects the beauty-oriented type, the upper limit of sunbathing time may be the same as the upper limit of sunbathing time when the user selects the health-oriented type, or may be shorter than the upper limit of sunbathing time when the user selects the health-oriented type.

[0060] The balance-oriented type is a type that emphasizes the balance between the expectation of vitamin D production and the expectation of reducing the risk of sunburn. In other words, the balance-oriented type is an intermediate type between the health-oriented type and the beauty-oriented type. When a user selects the balance-oriented type, the target sunbathing time is an intermediate time between the target sunbathing time when the user selects the health-oriented type or the beauty-oriented type. Furthermore, when a user selects the balance-oriented type, the upper limit of sunbathing time may be the same as the upper limit of sunbathing time when the user selects the health-oriented type or the beauty-oriented type, or may be an intermediate time between the upper limit of sunbathing time when the user selects the health-oriented type or the beauty-oriented type.

[0061] When the information processing device 20 is performing the initial setup, the second control unit 22 displays an initial setup screen on the display unit 24. Fig. 2 shows an example of the display unit 24 of the information processing device 20 displaying the initial setup screen.

[0062] 2, the second control unit 22 causes the display unit 24 to display a skin type selection button 101 and a target type selection button 102. The user can make various selections by operating the input unit 23.

[0063] In the example shown in Fig. 2, the user selects "Type 3" as the skin type, and the user selects "Balance-oriented Type" as the target type.

[0064] When the user selects a skin type and a target type by operating the input unit 23, the second control unit 22 stores the selected skin type and target type in the storage unit 25 as initial settings.

[0065] When starting sunbathing, the user operates the information processing device 20 to launch an application for calculating the recommended sunbathing time. Fig. 3 shows an example of the initial screen displayed on the display unit 24 of the information processing device 20 when the user starts sunbathing.

[0066] In the example shown in FIG. 3 , the second control unit 22 causes the display unit 24 to display a goal type 201, a sunbathing timer 202, a goal time 203, an upper limit time 204, a measurement button 205, an outfit button 206, and a start button 207.

[0067] The goal type 201 displays the goal type selected by the user in the initial setting. In the example shown in Fig. 3, "beauty-oriented type" is selected in the initial setting, so "beauty-oriented type" is displayed.

[0068] The sunbathing timer 202 displays the target sunbathing time and the upper limit sunbathing time. When the initial screen shown in Figure 3 is displayed, the target time and the upper limit time have not yet been calculated, so specific values ​​for the target time and the upper limit time are not displayed.

[0069] The target time for sunbathing is displayed as a target time 203. When the initial screen shown in Fig. 3 is displayed, the target time has not yet been calculated, and therefore no specific value for the target time is displayed.

[0070] The upper limit time 204 displays the upper limit time for sunbathing. At the stage when the initial screen shown in Fig. 3 is displayed, the upper limit time has not yet been calculated, so a specific value for the upper limit time is not displayed.

[0071] The measurement button 205 is a button for starting measurement of the amount of solar radiation. When the user operates the input unit 23 to press the measurement button 205, the power generation plant 10 and the information processing device 20 start measuring the amount of solar radiation.

[0072] After pressing the measurement button 205, the user points the energy harvesting unit 11 of the power generation device 10 toward the sun in order to measure the amount of solar radiation. To prompt the user to point the energy harvesting unit 11 toward the sun, the second control unit 22 of the information processing device 20 may display a message such as "Point the power generation device toward the sun" on the display unit 24 when the measurement button 205 is pressed.

[0073] When the energy harvesting unit 11 of the power generating device 10 receives sunlight after the measurement button 205 is pressed, the energy harvesting unit 11 outputs to the current detecting unit 12 a generated current corresponding to the amount of solar radiation received.

[0074] The current detection unit 12 detects the generated current supplied from the energy harvesting unit 11 and outputs the detected generated current to the first control unit 13 .

[0075] The first control unit 13 transmits the information on the generated current obtained from the current detection unit 12 to the information processing device 20 via the first communication unit 14 .

[0076] The second control unit 22 of the information processing device 20 acquires the information on the generated current transmitted by the power generation device 10 via the second communication unit 21 .

[0077] The clothing button 206 is a button for selecting the user's current clothing. When the user operates the input unit 23 to press the clothing button 206, the second control unit 22 causes the display unit 24 to display a screen for selecting clothing.

[0078] Fig. 4 shows an example of a screen for selecting clothing displayed on the display unit 24. In the example shown in Fig. 4, the second control unit 22 causes the display unit 24 to display an clothing selection button 301 and a decision button 302.

[0079] The outfit selection button 301 is a button for selecting the user's current outfit. In the example shown in Fig. 4, the options displayed are "swimsuit," "sleeveless and shorts," "short sleeves and shorts," "short sleeves and long pants," and "long sleeves and long pants." The user can select the current outfit by operating the input unit 23.

[0080] In the example shown in FIG. 4, the user has selected "short sleeves and long pants" as their current outfit. The user's outfit is related to the user's exposed skin area, and the user's exposed skin area varies depending on the outfit. The smaller the exposed skin area, the longer it takes to synthesize vitamin D, and the larger the exposed skin area, the shorter it takes to synthesize vitamin D. Therefore, the smaller the exposed skin area of ​​the outfit worn, the longer the target sunbathing time. Furthermore, the larger the exposed skin area of ​​the outfit worn, the shorter the target sunbathing time. Note that the upper limit of sunbathing time may be independent of the outfit, or may be longer for outfits with a smaller exposed skin area and shorter for outfits with a larger exposed skin area.

[0081] The decision button 302 is a button for deciding the outfit selected by the outfit selection button 301. When the decision button 302 is pressed by the user operating the input unit 23, the second control unit 22 decides the user's current outfit.

[0082] 3 , when the measurement button 205 is pressed to measure the current solar radiation and the clothing button 206 is pressed to select the user's current clothing, the second control unit 22 calculates the target sunbathing time and the upper limit sunbathing time based on the information on the generated current acquired from the power generation device 10. The second control unit 22 may calculate the target sunbathing time and the upper limit sunbathing time based on the user's target type and skin type acquired during initial setup and the user's clothing (i.e., the user's exposed skin area), in addition to the information on the generated current. Note that the upper limit sunbathing time may or may not depend on the generated current, the user's target type, the user's skin type, and the user's clothing.

[0083] In the above description, the second control unit 22 calculates the target sunbathing time and the upper limit sunbathing time based on the user's target type, the user's skin type, and the user's clothing in addition to the information on the generated current. However, more generally, the second control unit 22 may calculate the target sunbathing time and the upper limit sunbathing time based on the user's target type and at least one piece of information related to the user's skin in addition to the information on the generated current. The user's skin type and the user's clothing are examples of information related to the user's skin, and the information related to the user's skin is not limited to these. In the following description, a case where the information related to the user's skin is the user's skin type and the user's clothing will be described as an example.

[0084] The memory unit 25 stores an algorithm for calculating a target sunbathing time and an upper limit sunbathing time from the generated current. The algorithm for calculating the target time and upper limit sunbathing time stored in the memory unit 25 may be an algorithm created based on pre-measured data. The pre-measured data for creating the algorithm may be, for example, data correlating the generated current with the amount of vitamin D produced, data correlating the generated current with sunburn, etc.

[0085] The second control unit 22 calculates the target time and upper limit time for sunbathing based on the information on the generated current obtained from the power generation device 10, using an algorithm for calculating the target time and upper limit time stored in the memory unit 25.

[0086] The algorithm stored in the memory unit 25 may be an algorithm that calculates a target sunbathing time and an upper limit sunbathing time based on the user's target type, the user's skin type, and the user's clothing in addition to the generated current. The second control unit 22 may use the algorithm stored in the memory unit 25 to calculate a target sunbathing time and an upper limit sunbathing time based on the user's target type, the user's skin type, and the user's clothing in addition to the generated current information acquired from the power generation device 10.

[0087] After calculating the target sunbathing time and the upper limit sunbathing time, the second control unit 22 causes the display unit 24 to display the target sunbathing time and the upper limit sunbathing time.

[0088] FIG. 5 shows an example in which the display unit 24 displays the target sunbathing time and the upper limit of the sunbathing time.

[0089] In the example shown in Figure 5, the second control unit 22 displays a goal type 401, a sunbathing timer 402, a target time 403, an upper limit time 404, a measurement button 405, an outfit button 406, and a start button 407 on the display unit 24.

[0090] The screen shown in FIG. 5 is a screen transitioned from the screen shown in FIG. 3 after the target sunbathing time and the upper limit sunbathing time have been calculated.

[0091] In the example shown in Fig. 5, the target time for sunbathing is calculated to be 25 minutes. Furthermore, the upper limit for sunbathing is calculated to be 45 minutes. Therefore, the sunbathing timer 402 displays the calculated target time of 25 minutes and the calculated upper limit of 45 minutes. Furthermore, the target time 403 displays the calculated target time of 25 minutes. Furthermore, the upper limit of 45 minutes is displayed as the calculated upper limit.

[0092] The start button 407 is a button that the user presses when starting sunbathing. When the user is ready to start sunbathing, the user operates the input unit 23 to press the start button 407. When the user operates the input unit 23 to press the start button 407, the second control unit 22 causes the display unit 24 to display a screen indicating that sunbathing is in progress, and starts a countdown until the target time ends.

[0093] FIG. 6 shows an example of a screen displayed on the display unit 24 when sunbathing is in progress.

[0094] In the example shown in FIG. 6, the second control unit 22 causes the display unit 24 to display a sunbathing image screen 501, a remaining time 502, and a stop button 503.

[0095] The sunbathing image screen 501 is an image or video that gives the impression of sunbathing.

[0096] The remaining time 502 is a countdown display of the time remaining until the target time is reached. Figure 6 shows the display when 48 seconds have passed since the start of sunbathing, and since the target time is 25 minutes, the remaining time displayed is 24 minutes and 12 seconds.

[0097] The stop button 503 is a button that the user presses when he or she wants to finish sunbathing. When the user has finished sunbathing, the user operates the input unit 23 to press the stop button 503. When the user operates the input unit 23 to press the stop button 503, the second control unit 22 stores in the memory unit 25 the time the user actually spent sunbathing.

[0098] When the second control unit 22 stores the time when the user actually sunbathed in the storage unit 25, the second control unit 22 associates the time when the user actually sunbathed with the date of sunbathing, the target time for sunbathing, etc., and stores them in the storage unit 25.

[0099] The second control unit 22 calculates the degree of achievement of at least two indices based on the actual sunbathing time of the user and the target sunbathing time. The indices may be, for example, a first indice for maintaining physical and mental health (an indice expected to produce vitamin D), a second indice for maintaining physical and mental health (an indice expected to maintain biological rhythms), and a third indice for maintaining healthy skin.

[0100] That is, for example, the second control unit 22 calculates the degree of achievement of a first index for maintaining mental and physical health based on the actual amount of time the user spent sunbathing and the target amount of time for sunbathing. The second control unit 22 also calculates the degree of achievement of a second index for maintaining mental and physical health based on the actual amount of time the user spent sunbathing and the target amount of time for sunbathing. The second control unit 22 also calculates the degree of achievement of a third index for maintaining healthy skin based on the actual amount of time the user spent sunbathing and the target amount of time for sunbathing.

[0101] The second control unit 22 may calculate the degree of achievement for each index using, for example, a five-point scale. An algorithm for calculating the degree of achievement for each index may be stored in the storage unit 25. The algorithm for calculating the degree of achievement stored in the storage unit 25 may be an algorithm created based on previously measured data.

[0102] The second control unit 22 can use an algorithm for calculating the degree of achievement stored in the memory unit 25 to calculate the degree of achievement for each indicator based on the time the user actually spent sunbathing and the target time for sunbathing.

[0103] For example, the degree of achievement of the first indicator for maintaining physical and mental health may be determined based on the general guideline time for which vitamin D production is expected, such as the level of impact on bones and muscles, the level of impact on the immune system, etc.

[0104] Furthermore, for example, the degree of achievement of the second indicator for maintaining physical and mental health may be determined based on the estimated time and conditions that are expected to reset and regulate the biological rhythm, leading to improved sleep quality, such as the feeling of waking up refreshed and refreshed by resetting the biological rhythm, the expectation of recovery from mental and physical fatigue due to the depth of sleep achieved by maintaining the biological rhythm, and the expectation of recovery from brain fatigue due to the amount of sleep that takes into account the appropriate length of sleep.

[0105] It is said that biological rhythms are regulated by exposure to sunlight of a predetermined illuminance (e.g., 1000 lux) or more for a predetermined period of time or more. Therefore, the second control unit 22 may calculate the degree of achievement of the second index, for example, based on whether or not exposure to sunlight of a predetermined illuminance or more for a predetermined period of time or more. Furthermore, it is said that if exposure to sunlight of a predetermined illuminance or more for a predetermined period of time or more is required, it is desirable to do so by around 10:00. Therefore, the second control unit 22 may calculate the degree of achievement of the second index, for example, based on whether or not exposure to sunlight of a predetermined illuminance or more for a predetermined period of time or more before a predetermined time (e.g., 10:00).

[0106] It is also said that biological rhythms can be regulated by exposure to sunlight with a predetermined illuminance (e.g., 1000 lux) or more for a predetermined period of time or more after a predetermined time (e.g., 10:00). Therefore, the second control unit 22 may calculate the achievement level of the second index based on whether or not the subject was exposed to sunlight with a predetermined illuminance or more for a predetermined period of time or more after the predetermined time (e.g., 10:00).

[0107] Furthermore, for example, the degree of achievement of the third index regarding maintaining healthy skin may be determined based on the estimated time for the risk of developing erythema on the skin, etc.

[0108] After calculating the degree of achievement for each of the indices, the second control unit 22 stores the degrees of achievement for at least two of the calculated indices in the storage unit 25 as an activity log.

[0109] The second control unit 22 can cause the display unit 24 to display the activity log for a predetermined period stored in the storage unit 25 for at least two indicators.

[0110] FIG. 7 shows an example of a screen on which the display unit 24 displays the achievement level of the first index for maintaining physical and mental health.

[0111] In the example shown in FIG. 7, the second control unit 22 causes the display unit 24 to display an indicator 601, a graph 602 of the achievement level, a display period selection button 603, a comment on the achievement level 604, and an achievement level 605.

[0112] The indicator 601 indicates the level of achievement for which indicator is being displayed. In the example shown in FIG. 7 , "Health Action" is displayed, which indicates that the level of achievement for the first indicator regarding maintaining physical and mental health is being displayed. When the level of achievement for the second indicator regarding maintaining physical and mental health is being displayed, the indicator 601 may be displayed as, for example, "Comfort Action." When the level of achievement for the third indicator regarding maintaining healthy skin is being displayed, the indicator 601 may be displayed as, for example, "Beauty Action." When the arrow shown to the left of the indicator 601 in FIG. 7 is pressed, the second control unit 22 displays the levels of achievement for the other indicators.

[0113] The achievement level graph 602 shows, in a bar graph, the achievement level for the period selected by the display period selection button 603. The achievement level in the achievement level graph 602 may be displayed using a five-level evaluation.

[0114] 7, since the targets are achievement levels 4 and 5, the range of achievement levels 4 and 5 is displayed with a colored background. Also, since the targets are achievement levels 4 and 5, medal symbols are drawn in the bar graph for dates where the achievement level is 4 or 5.

[0115] The display period selection button 603 is a button for selecting the period for which the achievement level is to be displayed. In the example shown in Fig. 7, "7 days" or "1 month" can be selected. In the example shown in Fig. 7, "7 days" is selected.

[0116] Comments about the achievement level are displayed in the comment about the achievement level 604. In the example shown in Fig. 7, an achievement level of 4 or 5 was achieved on four days out of seven days, so the notation "4 / 7" is displayed.

[0117] The achievement level 605 indicates the achievement level for the period selected by the display period selection button 603. In the example shown in FIG. 7, the achievement levels for 10 / 18 to 10 / 20 are hidden, but by scrolling, the achievement levels for 10 / 18 to 10 / 20 can also be displayed. In the example shown in FIG. 7, five levels of achievement are shown using terms. The relationship between the five levels of achievement and the terms may be as follows, for example. Note that the relationship between the following achievement levels and the terms is merely an example and is not limited to this. 5: Excellent 4: Great 3: Good 2: Poor 1: Low

[0118] After calculating the degree of achievement for the indexes, the second control unit calculates a total score based on the degree of achievement for at least two indexes.

[0119] FIG. 8 shows an example of a screen on which the display unit 24 displays the total score calculated based on the achievement level of the indexes.

[0120] In the example shown in FIG. 8, the second control unit 22 causes the display unit 24 to display a date 701, a total score 702, and a level of achievement 703.

[0121] The date 701 indicates the date on which the total score is displayed. When the arrow shown to the left or right of the date 701 in Fig. 8 is pressed, the second control unit 22 displays the total scores for other dates.

[0122] The total score 702 indicates the total score. In the example shown in Fig. 8, "90" is displayed as the total score.

[0123] The achievement level 703 indicates the achievement level for each of the indicators. In the example shown in FIG. 8 , the achievement level for the first indicator regarding maintaining physical and mental health is indicated as "Health Action" and the achievement level is "Excellent." The achievement level for the third indicator regarding maintaining healthy skin is indicated as "Beauty Action" and the achievement level is "Good." The achievement level for the second indicator regarding maintaining physical and mental health is indicated as "Comfort Action" and the achievement level is "Poor."

[0124] <Weather Forecast> The information processing device 20 can acquire weather forecast information from a server that distributes weather forecast information, and display recommended times for sunbathing based on the acquired weather forecast information.

[0125] The weather forecast information may include information on forecast values ​​for ultraviolet rays, such as the UV index.

[0126] The recommended time for sunbathing may be calculated based on at least one of the indicators. Alternatively, the recommended time for sunbathing may be calculated for each of the indicators.

[0127] FIG. 9 shows an example of a screen on which the display unit 24 displays recommended times for sunbathing based on weather forecast information acquired from the server.

[0128] In the example shown in Figure 9, the second control unit 22 causes the display unit 24 to display a comment 801, today's weather 802, today's recommended sunbathing time 803, a weekly forecast 804, and recommended sunbathing times from tomorrow onwards 805.

[0129] Comment 801 displays a comment about recommended sunbathing information based on today's weather.

[0134] By checking the sunbathing recommendation information as shown in FIG. 9, the user can easily plan sunbathing for the current day and the following days.

[0135] The operation of the recommended sunbathing time calculation system 1 will be described with reference to the flowchart shown in FIG.

[0136] Step S101: Before the user starts sunbathing, the energy harvesting unit 11 of the power generation device 10 receives sunlight. At this time, the user points the energy harvesting unit 11 toward the sun.

[0137] Step S102: The current detection unit 12 detects the generated current supplied from the energy harvesting unit 11 and outputs the detected generated current to the first control unit 13. The first control unit 13 transmits the information on the generated current obtained from the current detection unit 12 to the information processing device 20 via the first communication unit 14.

[0138] Step S103: The second control unit 22 of the information processing device 20 acquires the information on the generated current transmitted by the power generation device 10 via the second communication unit 21. The second control unit 22 calculates the target sunbathing time and the upper limit sunbathing time based on the information on the generated current acquired from the power generation device 10. The second control unit 22 may calculate the target sunbathing time and the upper limit sunbathing time based on the information on the generated current acquired from the power generation device 10, as well as the user's target type, the user's skin type, and the user's clothing.

[0139] Step S104: The second control unit 22 causes the display unit 24 to display the calculated target sunbathing time and upper limit sunbathing time.

[0140] Step S105: Having confirmed the target sunbathing time and the upper limit sunbathing time, the user can start sunbathing with the target time as the target.

[0141] The recommended sunbathing time calculation system 1 can also notify the user before the target sunbathing time and the upper limit of sunbathing time are reached.

[0142] The recommended sunbathing time calculation system 1 can calculate the amount of solar radiation that the user will be exposed to in the future based on, for example, weather forecast information, and can also issue a warning based on conditions set by the user.

[0143] As described above, the recommended sunbathing time calculation system 1 according to this embodiment includes a power generation device 10 and an information processing device 20. The power generation device 10 includes an environmental power generation unit 11 that outputs a generated current according to the amount of solar radiation received from sunlight, and a first control unit 13 that transmits information about the generated current to the information processing device 20. The information processing device 20 includes a second control unit 22 that calculates a target sunbathing time and an upper limit sunbathing time based on the information about the generated current. As described above, the recommended sunbathing time calculation system 1 according to this embodiment can calculate a target sunbathing time and an upper limit sunbathing time according to the amount of solar radiation measured by the power generation device 10 at that time. In other words, the recommended sunbathing time calculation system 1 according to this embodiment can calculate a recommended guideline sunbathing time according to the amount of solar radiation at that time. This allows a user of the recommended sunbathing time calculation system 1 to sunbathe for an appropriate time according to the amount of solar radiation at that time.

[0144] In this embodiment, the user detects the generated current by pointing the energy harvesting unit 11 toward the sun, but the generated current may also be detected by automatically adjusting the orientation of the energy harvesting unit 11 based on information obtained from the aforementioned gyro sensor.

[0145] The above description merely shows one embodiment of the present invention, and it goes without saying that various modifications may be made within the scope of the claims.

[0146] For example, a general-purpose electronic device or device such as a computer may be configured to function as the information processing device 20 according to the above-described embodiment.
