Description

  The present invention relates to an information processing apparatus and a method for controlling the information processing apparatus.

  In recent years, a GPS (Global Positioning System) module for specifying a current position and an information processing apparatus equipped with a power generation mechanism have been widely used. For example, Patent Document 1 discloses an information processing apparatus equipped with a GPS module and a solar battery which is a kind of power generation mechanism. The information processing apparatus stores position information specified by the GPS module and charge amount information indicating a charge amount of the secondary battery charged by the solar battery at the position indicated by the position information. The position information and the charge amount information Based on the above, the amount of charge by the solar battery at the planned charging position is predicted.

JP 2012-65421 A

  However, in the above-described conventional information processing apparatus, even if the amount of charge by the solar battery can be predicted, the power consumption of the device such as the GPS module varies depending on the activity performed by the user. There is a possibility that the estimation accuracy is lowered.

  An information processing apparatus according to a preferred aspect (first aspect) of the present invention includes a secondary battery, a power generation mechanism that supplies generated power to the secondary battery, a device that is supplied with power from the secondary battery, A processor, and the processor is configured to calculate an estimated power generation unit and an estimated power consumption of the device in an activity scheduled to be performed by a user, and a remaining battery level of the secondary battery. And an operable time calculation unit that calculates an operable time of the device based on the estimated generated power and the estimated power consumption.

  The generated power is the amount of generated power per unit time, and the power consumption is the amount of power consumed per unit time. In the above aspect, the generated power and the power consumption vary depending on the activity scheduled to be performed by the user, but the estimated generated power and the estimated power consumption reflect the influence of the activity scheduled to be performed by the user. According to the above aspect, the estimation accuracy of the operable time of the device is higher than in the case where the activity scheduled to be performed by the user is not taken into consideration.

  The suitable example (2nd aspect) of a 1st aspect is provided with the display part which displays the said operation possible time.

  According to the above aspect, the user can view the operable time displayed on the display unit and grasp how much time activity can be performed without performing the charging operation. Furthermore, the user can predict the timing for performing the charging operation.

  In a preferred aspect (third aspect) of the first aspect and the second aspect, the estimated power calculation unit refers to the generated power information that associates the type of activity of the user with the generated power of the power generation mechanism, The generated power corresponding to the activity scheduled to be performed by the user is calculated as the estimated generated power, and the user refers to power consumption information that associates the type of the user's activity with the power consumption of the device. The power consumption of the device corresponding to the activity to be performed is calculated as the estimated power consumption.

  In the above aspect, the device operable time is specified with reference to the generated power information and the power consumption information associated with the type of activity. Types of activities include outdoor sports and indoor sports, for example. As for generated power, in outdoor sports, a solar cell, which is an example of a power generation mechanism, can generate a large amount of electricity compared to indoor sports. Therefore, the generated power is used for outdoor sports and indoor sports. There is a big difference. Regarding power consumption, in outdoor sports, the user may move much more than in indoor sports. Accordingly, in outdoor sports, a GPS module, which is an example of a device, needs to operate. However, in indoor sports, the GPS module does not need to operate, so power consumption is performed when performing outdoor sports and when performing indoor sports. There is a big difference with the case. Therefore, in the above aspect, since the generated power information and the power consumption information associated with the type of activity are referred to, it is possible to accurately estimate the device operable time as compared with the case where the type of activity is not considered. become.

  In an aspect (fourth aspect) suitable for the third aspect, the processor includes an updating unit that updates the power consumption information based on the power consumption when the activity is performed.

  In the above aspect, the power consumption information reflects the history of the power consumption of the device when the activity is performed. By calculating the estimated power consumption based on the power consumption history, the estimation accuracy of the device operable time is higher than in the case where the consumed power history is not taken into consideration.

  In a fifth aspect suitable for the third aspect, the processor includes an updating unit that updates the generated power information based on the generated power when the activity is performed.

  According to the above aspect, the generated power information reflects the history of the generated power of the power generation mechanism when the activity is performed. By calculating the estimated generated power based on the history of generated power, the accuracy of estimating the device operable time is higher than in the case where the generated power history is not considered.

  In a preferred example (sixth aspect) of the first to fifth aspects, the processor calculates the scheduled activity time zone of the user based on schedule information related to the activity scheduled to be performed by the user, and the scheduled activity time. A weather information acquisition unit that acquires weather information according to a band, and the estimated power calculation unit determines whether the schedule information is changed based on the weather information acquired by the weather information acquisition unit. When it is determined that the schedule information is to be changed, the estimated generated power and the estimated power consumption are calculated based on the schedule information after the change.

  In general, the user changes the actual activity according to the weather. For example, even if the user plans to perform outdoor sports, the user may perform indoor sports if the weather is raining. According to the above aspect, since the change of the schedule information is determined based on the weather information corresponding to the time zone in which the user performs the scheduled activity, the device operation is compared with the case where the change of the schedule information is not considered. The estimation accuracy of the possible time is increased.

  In a preferred example (seventh aspect) of the first aspect to the fifth aspect, the device includes a weather information acquisition unit that measures the position of the user and acquires weather information indicating a weather forecast according to the position of the user. The estimated power calculation unit determines whether or not the schedule information related to the activity scheduled to be performed by the user is changed based on the weather information acquired by the weather information acquisition unit, and the schedule information is When it is determined to be changed, the estimated generated power and the estimated power consumption are calculated based on the schedule information after the change.

  In the above aspect, the position where the user is active is regarded as the current position, and the weather forecast corresponding to the position measured by the device is acquired. Therefore, according to the above aspect, since the change of the schedule information is estimated based on the weather forecast corresponding to the current position where the user performs the scheduled activity, the device is compared with the case where the change of the schedule information is not considered. The accuracy of estimation of the operable time of becomes higher.

  In a preferred example of the first aspect to the seventh aspect (eighth aspect), the operable time calculation unit includes a remaining battery level of the secondary battery, and differential power obtained by subtracting the estimated generated power from the estimated power consumption. Based on the above, the operable time is calculated.

  The estimated power consumption and the estimated generated power in the scheduled activity may be uniform for all time zones of the scheduled activity, or may vary depending on the scheduled activity time. When the estimated power consumption and the estimated generated power in the scheduled activity are fixed according to the time of the scheduled activity, the estimated generated power is calculated from the remaining battery level of the secondary battery and the estimated power consumption by the above mode. The simple operation of calculating the operable time based on the subtracted differential power makes it possible to obtain the operable time of the device.

  A control method for an information processing apparatus according to a preferred aspect (ninth aspect) of the present invention includes a secondary battery, a power generation mechanism that supplies generated power to the secondary battery, and power supplied from the secondary battery. A method for controlling an information processing apparatus comprising: a device, wherein the information processing apparatus calculates an estimated generated power of the power generation mechanism and an estimated power consumption of the device in an activity scheduled to be performed by a user; Based on the remaining battery level of the secondary battery, the estimated generated power, and the estimated power consumption, the operable time of the device is calculated.

  In the above aspect, the estimated generated power and the estimated power consumption reflect the influence of the activity scheduled to be performed by the user. Since the generated power and the power consumption vary depending on the activity scheduled to be performed by the user, according to the above aspect, the estimated accuracy of the device operable time compared with the case where the activity scheduled to be performed by the user is not considered. Becomes higher.

For example, the pulse sensor 21 includes a light emitting unit, a light receiving unit, an amplifier, a band pass filter, and an AD converter. The light emitted from the light emitting unit is reflected by a human tissue such as a blood vessel and is incident on the light receiving unit. The light receiving unit generates a photoelectrically converted signal, that is, a pulse signal. The AD converter AD converts the signal output from the light receiving unit to generate pulse signal data, and outputs the generated pulse signal data to the control unit 70. Since the amount of light absorption from the light emitting part due to hemoglobin contained in blood flowing through the living body's blood vessels changes in conjunction with the heart beat, the amount of light incident on the light receiving part is the propagation of the heart beat, It depends on the pulse. The control unit 70 calculates the user's pulse rate, pulse interval (RR interval), pulse fluctuation (HRV), etc. based on the pulse signal output from the pulse sensor 21 or pulse signal data obtained by digitally converting the pulse signal.

The control unit 70 reads and executes the program stored in the storage unit 61, thereby realizing an acquisition unit 701, an estimated power calculation unit 702, an operable time calculation unit 703, and an update unit 706. The acquisition unit 701 is an example of a weather information acquisition unit. The storage unit 61 stores generated power information 611, power consumption information 612, activity information 613, weather information 614, activity determination information 615, generated power statistics information 616, and power consumption statistics information 617. The Hereinafter, the configuration of the control unit 70 will be described with respect to the operable time display process for displaying the operable time and the update process for updating the generated power information 611 and the power consumption information 612 used for specifying the operable time. . In the following description, it is assumed that the current time is 8:00 am on December 9, and the activity is either outdoor sports or indoor sports to simplify the description.

A. 2.1. Configuration of Control Unit 70 in Operable Time Display Process The estimated power calculation unit 702 estimates the estimated generated power that is the generated power of the power generation mechanism 50 and the estimated power consumption that is the power consumption of the activity-related device in the scheduled activity. The generated power is the amount of generated power per unit time, and the power consumption is the amount of power consumed per unit time. The unit time is, for example, 1 second, 1 minute, or 1 hour. In the present embodiment, it is assumed that the estimated power consumption and the estimated generated power in the scheduled activity are uniform for all times of the scheduled activity. There are the following four methods for specifying the scheduled activity.

A. 2.1.1. Identification of Scheduled Activity In the first method for specifying the schedule activity, the estimated power calculation unit 702 refers to the schedule information indicating the schedule activity, and directly specifies the schedule activity to be implemented in the future as the schedule activity. In the second method for specifying the scheduled activity, the estimated power calculation unit 702 estimates a change in the scheduled activity according to the weather forecast in the time zone of the scheduled activity. In the third method of specifying the scheduled activity, the estimated power calculation unit 702 estimates a change in the scheduled activity according to the weather forecast of the position of the scheduled activity to be performed in the future. In the fourth method of specifying the scheduled activity, the estimated power calculation unit 702 estimates a change in the scheduled activity according to the weather forecast of the time zone and position of the scheduled activity to be performed in the future. The fourth method for specifying the scheduled activity is a combination of the second method for specifying the scheduled activity and the third method for specifying the scheduled activity. The second method for specifying the scheduled activity, the third method for specifying the scheduled activity, and the fourth method for specifying the scheduled activity use the weather forecast.

  FIG. 5 shows a weather forecast indicated by the weather information 614. FIG. 5 shows the weather information 614 in an aspect corresponding to the fourth method for specifying the scheduled activity. The weather information 614 in this aspect indicates a weather forecast corresponding to the time zone and position. Of the cells in the table t614 shown in FIG. 5, the shaded cells indicate the names of columns or rows. Columns in table t614 relate to time zones and rows relate to positions. Table t614 shows the weather forecast of each position in each time zone of each day. For example, the table t614 indicates that the rain at position A, the rain at position B, and the snow at position C in the time zone from 12:00 to 18:00 on December 9.

  The weather information 614 in a mode corresponding to the second method for specifying the scheduled activity indicates a weather forecast for each time zone corresponding to only one row, that is, one position, although not shown. Similarly, the weather information 614 in the aspect corresponding to the third method for specifying the scheduled activity shows the weather forecast of each position corresponding to only one column, that is, one time zone, although not shown.

Returning to FIG.
In the first method for specifying a scheduled activity, the acquisition unit 701 acquires an activity scheduled to be performed by the user. Specifically, the acquisition unit 701 refers to the activity information 613 illustrated in FIG. 6 and acquires an activity scheduled to be performed by the user. The activity information 613 is an example of “schedule information”. The activity information 613 relates to an activity performed by the user and an activity scheduled to be performed by the user.

  FIG. 6 shows the implemented activity and the scheduled activity indicated by the activity information 613. Table t613 shown in FIG. 6 shows what activities were or will be performed on each day. The rectangles shown in table t613 indicate activity, the shaded rectangles indicate outdoor sports, and the blacked rectangles indicate indoor sports. The positions and lengths of the rectangles shown in the table t613 indicate the time zone when the activity is performed or the time zone where the activity is scheduled to be performed.

  FIG. 6 shows an activity 6131 performed by the user in the past from the current time and an activity 6132 scheduled to be performed by the user in the future from the current time. Activities 6131 include outdoor sports o1, indoor sports i1, indoor sports i2, indoor sports i3, outdoor sports o4, indoor sports i5, indoor sports i6, outdoor sports o7, and indoor sports i8. Activities 6132 include outdoor sports o9 and indoor sports i9.

  The acquisition unit 701 refers to the activity information 613 and acquires, for example, outdoor sports o9. As shown in FIG. 6, the outdoor sport o9 indicates that the outdoor sport is scheduled to be performed for 1 hour from 14:00 to 15:00.

Returning to FIG.
In the second method of specifying the scheduled activity, the estimated power calculation unit 702 determines whether or not the activity information 613 is changed according to the weather forecast for the scheduled activity time zone. Specifically, the estimated power calculation unit 702 identifies a scheduled activity time zone that is a scheduled activity time zone based on the activity information 613. The acquisition unit 701 acquires the weather information 614 in a mode corresponding to the second method for specifying the scheduled activity according to the scheduled activity time zone. Then, the estimated power calculation unit 702 determines whether or not the activity information 613 is changed based on the weather information 614 acquired by the acquisition unit 701.
For example, the estimated power calculation unit 702 refers to the activity information 613 and specifies that the time zone of the outdoor sport o9 is from 14:00 to 15:00, that is, the scheduled activity time zone is from 14:00 to 15:00. When the weather information 614 acquired by the acquisition unit 701 indicates that the time zone including the scheduled time zone from 14:00 to 15:00 is rain, the estimated power calculation unit 702 includes the activity information 613. It is determined that the scheduled activity is changed from outdoor sports to indoor sports.

In the third method of specifying the scheduled activity, the estimated power calculation unit 702 determines whether the scheduled activity is changed according to the weather forecast of the location of the scheduled activity. In the third method of specifying the scheduled activity, the position of the scheduled activity is regarded as the current position. Specifically, the acquisition unit 701 acquires the weather information 614 in an aspect corresponding to the third method for specifying the scheduled activity, which indicates a weather forecast according to the position measured by the GPS module 22. Then, the estimated power calculation unit 702 determines whether or not the activity information 613 is changed based on the weather information 614 acquired by the acquisition unit 701.
For example, when the current position is the position A, the acquisition unit 701 acquires the weather information 614 corresponding to the position A measured by the GPS module 22. When the weather information 614 acquired by the acquisition unit 701 indicates that the position A is rain, the estimated power calculation unit 702 determines that the scheduled activity of the activity information 613 is changed from outdoor sports to indoor sports. To do.

In the fourth method of specifying the scheduled activity, the estimated power calculation unit 702 estimates whether the scheduled activity is changed according to the position of the scheduled activity and the weather forecast for the time zone. In the fourth method for specifying the scheduled activity, the position of the scheduled activity is regarded as the current position. Specifically, the estimated power calculation unit 702 specifies the time zone of the scheduled activity based on the activity information 613. The acquisition unit 701 acquires the weather information 614 in a mode corresponding to the fourth method of specifying the scheduled activity, which indicates the weather forecast according to the position measured by the GPS module 22 in the specified time zone. Then, the estimated power calculation unit 702 estimates whether or not the activity information 613 is changed based on the weather information 614 acquired by the acquisition unit 701.
For example, the estimated power calculation unit 702 refers to the activity information 613 and specifies that the time zone of the outdoor sports o9 is from 14:00 to 15:00. For example, when the current position is the position A, the acquisition unit 701 acquires the weather information 614 corresponding to the time zone including 14:00 to 15:00 of the position A measured by the GPS module 22. If the example of FIG. 5 is used, since the time zone including the 14:00 to 15:00 position A is rain, the estimated power calculation unit 702 changes the scheduled activity of the activity information 613 from outdoor sports to indoor sports. Is determined.

  In the following, description will be made using an example in which the fourth method for specifying the scheduled activity is adopted.

  The estimated power calculation unit 702 calculates the estimated generated power that is the generated power of the power generation mechanism 50 and the estimated power consumption that is the power consumption of the activity-related device in the specified scheduled activity. When the estimated power calculation unit 702 determines that the scheduled activity is to be changed, the estimated power calculation unit 702 determines the estimated generated power that is the generated power of the power generation mechanism 50 and the activity-related in the scheduled activity after the change. The estimated power consumption that is the power consumption of the device is calculated. Hereinafter, estimation of estimated generated power and estimation of estimated power consumption will be described.

A. 2.1.2. Estimation of Estimated Generated Power The estimated power calculation unit 702 refers to the generated power information 611 shown in FIG. 7 and identifies the generated power corresponding to the scheduled activity as the estimated generated power.

  FIG. 7 shows an example of the generated power information 611. A table t611 illustrated in FIG. 7 is an example of the generated power information 611. The generated power information 611 associates the type of user activity with the generated power. Furthermore, the generated power information 611 associates the user's sleep, the neglect of the information processing apparatus 100, and the normal operation of the information processing apparatus 100 with the generated power, in addition to the type of user activity.

  The neglect of the information processing apparatus 100 is a state where the information processing apparatus 100 is placed on a desk or the like without the user wearing the information processing apparatus 100. The normal operation of the information processing apparatus 100 is a state in which the user wears the information processing apparatus 100 and the user is not sleeping. Hereinafter, for simplification of description, the user's sleep is described as “sleep”, the leaving of the information processing apparatus 100 as “leaving”, and the normal operation of the information processing apparatus 100 as “normal operation”.

The generated power information 611 indicates the generated power of the power generation mechanism 50 according to the activity performed by the user for a unit time, the sleep for the unit time, the leaving of the unit time, and the normal operation for the unit time. Among the cells in the table t611, the shaded cells indicate the names of columns or rows. In addition, among the cells in the table t611, a value of “xxx” is set to a value greater than zero. On the other hand, 0 is set for a cell having a value of “−”.
For example, when the user performs outdoor sports for a unit time, the solar cell 51, the kinetic mechanism 52, the thermoelectric conversion device 53, and the biofuel cell 54 generate electric power corresponding to each cell in Table t611.

  “High”, “Mid”, and “Low” of the solar cell 51, the thermoelectric conversion device 53, and the biofuel cell 54 indicate the degree of generated power. For example, “High” of the solar cell 51 indicates that light of 10,000 lux or more is incident on the solar cell 51 and the solar cell 51 generates electric power close to the maximum electric power that can be generated. “Mid” of the solar cell 51 means that light of 1000 lux or more and less than 10000 lux is incident on the solar cell 51, and the solar cell 51 generates about half of the maximum power that can be generated. Show. “Low” of the solar cell 51 indicates that light of 500 lux or more and less than 1000 lux is incident on the solar cell 51, and the solar cell 51 generates electric power close to the minimum electric power that can be generated. The indoor brightness is usually 1000 lux or less, and as shown in Table t611, when the user performs indoor sports, the solar cell 51 generates power indicated by “Low”.

  For example, when the scheduled activity is outdoor sports, the estimated power calculation unit 702 specifies the total generated power of the solar cell 51, the kinetic mechanism 52, the thermoelectric conversion device 53, and the biofuel cell 54 as the estimated generated power. . The generated power of the solar cell 51 is the sum of the generated power of “High”, “Mid”, and “Low” of the solar cell 51. The generated power of the thermoelectric conversion device 53 is the sum of the generated power of “High”, “Mid”, and “Low” of the thermoelectric conversion device 53. The generated power of the biofuel cell 54 is the sum of the generated power of “High”, “Mid”, and “Low” of the biofuel cell 54.

A. 2.1.3. Estimation of Estimated Power Consumption Returning to FIG.
The estimated power calculation unit 702 refers to the power consumption information 612 illustrated in FIG. 8 and identifies the power consumption of the device corresponding to the scheduled activity as the estimated power consumption.

  FIG. 8 shows an example of the power consumption information 612. A table t612 illustrated in FIG. 7 is an example of the power consumption information 612. The power consumption information 612 indicates information that associates the type of activity of the user with the power consumption of the activity-related device. Furthermore, the power consumption information 612 associates sleep, neglect, and normal operation with power consumption in addition to the type of user activity.

The power consumption information 612 indicates the power consumption of the activity-related device according to the activity performed by the user for a unit time, sleep for the unit time, leaving the unit time, and the normal operation for the unit time. Among the cells in the table t612, a cell to which shading is given indicates a column or row name. Among the cells in table t612, a value of “xxx” is set to some value greater than zero. On the other hand, 0 is set for a cell having a value of “−”.
For example, when the user carries out outdoor sports for a unit time, the GPS module 22, the pulse sensor 21, the acceleration sensor 24, the acceleration sensor 24, the communication unit 30, and the display unit 41 use power corresponding to each cell in the table t612. Consume.

  “High” and “Low” of the GPS module 22, the pulse sensor 21, and the display unit 41 indicate the degree of generated power. “High” and “Low” indicate the degree of power consumption. In general, the GPS module 22 consumes power indicated by “High” when searching for satellites, and consumes power indicated by “Low” when searching for satellites.

  “High” and “Low” of the pulse sensor 21 are power consumption corresponding to the frequency of measuring the pulse. “High” and “Low” on the display unit 41 are power consumptions corresponding to the frequency of updating the screen.

  For example, when the planned activity is indoor sports, the estimated power calculation unit 702 uses the total power consumption of the pulse sensor 21, the acceleration sensor 24, the atmospheric pressure sensor 23, the communication unit 30, and the display unit 41 as the estimated power consumption. Identify.

A. 2.1.4. Activity-related device operable time Return to the description of FIG.
The operable time calculation unit 703 specifies the operable time of the activity-related device based on the remaining battery level of the secondary battery 63, the estimated generated power, the estimated power consumption, and the unit time. For example, there are the following two methods for specifying the operable time of the activity-related device.

In the first method, the operable time calculation unit 703 specifies the operable time of the activity-related device based on the remaining battery level of the secondary battery 63 and the differential power obtained by subtracting the estimated generated power from the estimated power consumption. To do. More specifically, the operable time calculation unit 703 obtains a value obtained by dividing the remaining battery level of the secondary battery 63 by the amount of power obtained by multiplying the above-described differential power by unit time as the operable time of the activity-related device. Identify.
In the following calculation formula, in order to facilitate the calculation formula, the operable time of the activity-related device is calculated using the ratio of the secondary battery 63 to the amount of power in the fully charged state. Hereinafter, the power amount of the secondary battery 63 in the fully charged state is simply referred to as “full charge power amount”. For example, the remaining battery level of the secondary battery 63 is 80% with respect to the full charge power amount, the power amount obtained by multiplying the estimated power consumption by the unit time is 10% with respect to the full charge power amount, and the estimated generated power Assume that the power amount obtained by multiplying the unit time by 2% is 2% of the full charge power amount and the unit time is 1 hour. In this case, the operable time calculation unit 703 calculates the following equation (1) to specify the operable time of the activity-related device.

  Activity-related device operable time = 80 ÷ (10−2) = 10 hours (1)

  In the second method, the operable time calculation unit 703 generates an operable time table indicating the operable time of the activity-related device according to the combination of the remaining battery level of the secondary battery 63, the estimated power consumption, and the estimated generated power. Reference is made to determine the operational time of the activity-related device. The operable time table has, for example, the following three-dimensional data structure.

Operating time [Battery remaining i0%] [Estimated power consumption j0%] [Estimated generated power k0%] = xxx
...
Operating time [Battery remaining i0%] [Estimated power consumption j0%] [Estimated generated power k%] = xxx
...
Operable time [Battery level i0%] [Estimated power consumption j0%] [Estimated generated power kmax%] = xxx
Operable time [Battery level i0%] [Estimated power consumption j1%] [Estimated generated power k0%] = xxx
...
Operating time [Battery level i1%] [Estimated power consumption j0%] [Estimated power generation k%] = xxx
...
Operating time [Battery level i%] [Estimated power consumption j%] [Estimated power generation k%] = xxx
...
Operating time [Battery remaining imax%] [Estimated power consumption jmax%] [Estimated generated power kmax%] = xxx

  i is an integer from i0 to imax. j is an integer from j0 to jmax. k is an integer from k0 to kmax. For example, the operable time calculation unit 703 uses the values of the records corresponding to the remaining battery level, the estimated power consumption, and the estimated generated power of the secondary battery 63 among the records of the operable time table as the operation of the activity-related device. Specify as possible time.

A. 2.1.5. Display of operable time The display unit 41 displays the operable time specified by the operable time calculation unit 703. Operation possible time The above-mentioned image has three modes. The image in the first aspect shows only the operable time. The image in the second aspect shows operational time and activity. The image in the third aspect shows a graph showing the relationship between the operable time and the remaining battery level of the secondary battery 63. The image displayed by the display unit 41 in FIG. 1 is an image in the third mode.

A. 2.2. Configuration of Control Unit 70 in Update Process The update unit 706 updates the generated power information 611 and the power consumption information 612 that are information used to specify the operable time. Hereinafter, the update of the generated power information 611 and the update of the power consumption information 612 will be described.

A. 2.2.1. Update of Generated Power Information 611 The update unit 706 updates the generated power information 611 based on the power generated by the power generation mechanism 50 when the activity is performed. How much time activity has been performed is stored in the activity determination information 615 shown in FIG. The power generated by the power generation mechanism 50 when the activity is performed is stored in the generated power statistical information 616 shown in FIG.

  FIG. 9 shows an example of the activity determination information 615. A table t615 illustrated in FIG. 9 is an example of the activity determination information 615. The activity determination information 615 indicates the type of activity of the user and the time when the activity was performed for each day. Furthermore, the activity determination information 615 associates sleep, neglect, normal operation, and shutdown of the information processing apparatus 100 with time in addition to the type of user activity. Hereinafter, for simplification of description, the shutdown of the information processing apparatus 100 is referred to as “shutdown”.

The activity determination information 615 indicates a time corresponding to an activity performed by the user, sleep, neglect, normal operation, and shutdown. Among the cells in the table t615, the shaded cell indicates the column or row name. The numerical value set for each cell in table t615 indicates seconds.
For example, on December 1, the user has been running outdoor sports for 3600 seconds, ie, 1 hour, and indoor sports is being run for 600 seconds, ie, 10 minutes. Further, the user leaves the information processing apparatus 100 for 28800 seconds, that is, 8 hours, and normally operates 53400 seconds, that is, 14 hours and 50 minutes. The total time for outdoor sports, indoor sports, neglect and normal operation is 86400 seconds, that is, 24 hours.

There are, for example, the following two methods for specifying whether the user has performed an activity of outdoor sports or indoor sports.
In the first method, the information processing apparatus 100 specifies the type of activity by accepting it by a user operation. In the second method, the information processing apparatus 100 identifies the type of activity based on the generated power of the solar cell 51. For example, in the information processing apparatus 100, when the generated power of the solar battery 51 is equal to or greater than a predetermined threshold, the user performs outdoor sports, and when the generated power is less than the predetermined threshold, the user performs indoor sports. Is identified.

  FIG. 10 shows an example of the generated power statistics information 616. A table t616 illustrated in FIG. 10 is an example of the generated power statistics information 616. The generated power statistics information 616 indicates the power generation time generated by the power generation mechanism 50 for each day. Further, the generated power statistics information 616 indicates the time when power is supplied via the USB interface 31 in addition to the power generation mechanism 50.

The generated power statistics information 616 indicates the power generation time of the power generation mechanism 50 and the time when power is supplied. Among the cells in the table t616, a cell to which shading is given indicates a column or row name. The numerical value set for each cell in the table t616 indicates the second in the case of a cell related to other than the kinetic mechanism 52, and indicates the number of times in the case of a cell related to the kinetic mechanism 52.
For example, on December 1, the solar cell 51 indicates that the generated power indicated by “High” is generated for 3600 seconds.

The update unit 706 updates the generated power information 611 based on the activity determination information 615 and the generated power statistical information 616. For example, there are the following two methods of updating.
In the first updating method, the updating unit 706 sets the generated power obtained from the activity determination information 615 and the generated power statistical information 616 as the cell value of the generated power information 611 as it is. Specifically, the update unit 706 obtains the updated value of the cell in the i row and j column of the generated power information 611 by the following equation (2). i is an integer from 1 to 10. j is an integer of 1 to 5.

  Value after update of cell in i row and j column of generated power information 611 = a_gp × generated power of power generation mechanism 50 corresponding to i row of generated power information 611 (2)

  The “i-row generated power of the generated power information 611” in the formula (2) is the generated power of the power generation mechanism 50 in the case of continuously generating power during activity, sleep, neglect or normal operation. During the activity or the like, the power generation mechanism 50 does not always continue to generate power. For example, even if the user is engaged in outdoor sports, if the user enters a tunnel or the solar cell 51 is hidden behind a sleeve, the solar cell 51 can hardly generate power. Therefore, by multiplying by the coefficient a_gp, it is possible to reflect how much power can be generated during the activity or the like in the updated value. The coefficient a_gp is obtained by the following equation (3).

  a_gp = power generation time of i row of generated power statistics information 616 × time of j row of activity determination information 615 / (corresponds to activity, sleep, neglect, or normal operation whose value is greater than 0 in i row of generated power information 611 Total of time of activity judgment information 615) (3)

  The “power generation time of i row of the generated power statistics information 616” in the expression (3) is a power generation time from when the generated power information 611 is updated until now.

  For example, if i = 1 and j = 1 in the above equation (2), out of the user's activity, sleep, neglect, and normal operation, the value in the first line of the generated power information 611 is greater than 0 for outdoor sports Therefore, equation (2) can be transformed into equation (4) below. The updating unit 706 can obtain the updated value of the cell c1 related to “High” of the outdoor sports solar battery 51 in the generated power information 611 shown in FIG. 7 according to the equation (4).

  Value after update of cell c1 = “High” power generation time of solar cell 51 indicated by generated power statistical information 616 / time when outdoor sports indicated by activity determination information 615 × “High” generated power of solar cell 51 ( 4)

  For example, if i = 5 and j = 2 in the above equation (2), out of the user's activity, sleep, neglect, and normal operation, the value in the fifth line of the generated power information 611 is greater than 0 for outdoor sports And since it is an indoor sport, Formula (2) can be transformed into the following Formula (5). The updating unit 706 can obtain the updated value of the cell c2 related to “Mid” of the thermoelectric conversion device 53 for indoor sports in the generated power information 611 shown in FIG.

  Value after update of cell c2 = time of “Mid” of thermoelectric conversion device 53 indicated by generated power statistics information 616 × time of performing indoor sports indicated by activity determination information 615 / (implementing outdoor sports indicated by activity determination information 615 Time + time when the indoor sports indicated by the activity determination information 615) × “Mid” generated power of the thermoelectric conversion device 53 (5)

  Taking December 1 as an example, equation (5) is as follows.

  Value after update of cell c2 = 14400 × 600 / (3600 + 600) × power generation power of “Mid” of thermoelectric conversion device 53

  In the second update method, the update unit 706 calculates the average value of the value obtained by the above-described equation (2) and the value before the update of the cell in the i row and j column of the generated power information 611 as the generated power information. 611 is updated as the updated value of the cell in row i and column j.

A. 2.2.2. Update of power consumption information 612 Returning to the description of FIG.
The update unit 706 updates the power consumption information 612 based on the power consumed by the activity-related device when the activity is performed. The power consumed by the activity-related device when the activity is performed is stored in the power consumption statistics information 617.

  FIG. 11 shows an example of the power consumption statistical information 617. A table t617 illustrated in FIG. 11 is an example of the power consumption statistical information 617. The power consumption statistical information 617 indicates the consumption time for which the activity-related device consumed power for each day.

  Among the cells in the table t617, the shaded cells indicate the names of columns or rows. The numerical value set for each cell in table t616 indicates seconds. For example, on December 1, the GPS module 22 indicates that the power indicated by “High” has been consumed for 3600 seconds.

The update unit 706 updates the power consumption information 612 based on the activity determination information 615 and the power consumption statistical information 617. For example, there are the following two methods of updating.
In the first updating method, the updating unit 706 sets the power consumption obtained from the activity determination information 615 and the power consumption statistics information 617 as the cell value of the power consumption information 612 as it is. Specifically, the update unit 706 obtains the updated value of the cell in the i row and j column of the power consumption information 612 by the following equation (6).

  Value after update of cell in i row and j column of power consumption information 612 = a_cp × power consumption of activity-related device corresponding to i row of power consumption information 612 (6)

  The coefficient a_cp is obtained by the following equation (7).

  a_cp = time of i row of power consumption statistical information 617 × time of j row of activity determination information 615 / (corresponds to activity, sleep, neglect, or normal operation whose value is greater than 0 in i row of power consumption information 612 Total of time of activity judgment information 615) (7)

  About the example of (6) Formula, since it is the same as that of the method demonstrated by (2) Formula, description is abbreviate | omitted.

  In the second updating method, the updating unit 706 calculates the average value of the value obtained by the above-described expression (6) and the value before updating the cell in the i-th row and j-th column of the power consumption information 612 as the power consumption information. 612 is updated as the updated value of the cell in i row and j column.

A. 3. Flowchart of Each Process Each of the operable time display process and the update process will be described using a specific flowchart.

A. 3.1. Flow chart of operable time display process FIG. 12 shows a flowchart of the operable time display process. The control unit 70 receives a display instruction for the operable time display screen by the operation of the operation button 42 by the user (step S1). When the display instruction for the operable time display screen is received, the control unit 70 executes the operable time specifying process shown in FIG. 13 (step S2).

  FIG. 13 shows a flowchart of the operable time specifying process. The control unit 70 acquires the remaining battery level of the secondary battery 63 from the secondary battery 63 (step S11). Next, the control unit 70 executes a scheduled activity type specifying process shown in FIG. 14 (step S12).

  FIG. 14 shows a flowchart of the scheduled activity type specifying process. The acquisition unit 701 refers to the activity information 613 and acquires the time zone of today's scheduled activity (step S21). The acquisition unit 701 specifies the current position using the GPS module 22 (step S22). The acquisition unit 701 acquires the weather information 614 corresponding to the current position and the time zone in which the activity schedule is to be implemented (step S23).

  The estimated power calculation unit 702 determines whether the acquired weather forecast is clear or cloudy (step S24). When the acquired weather forecast indicates sunny or cloudy (step S24: Yes), the estimated power calculation unit 702 refers to the activity information 613 and identifies the type of scheduled activity corresponding to the acquired time zone (step S25). ). On the other hand, when the acquired weather forecast does not indicate sunny or cloudy (step S24: No), the estimated power calculation unit 702 estimates that the type of scheduled activity is changed to indoor sports (step S26). The estimated power calculation unit 702 outputs the type and time zone of the scheduled activity acquired or scheduled (step S27). After the process of step S27 is completed, the control unit 70 returns to the caller of the scheduled activity type specifying process.

Returning to the description of FIG.
The estimated power calculation unit 702 specifies estimated generated power corresponding to the specified type of scheduled activity (step S13). Further, the estimated power calculation unit 702 specifies estimated power consumption corresponding to the specified type of scheduled activity (step S14). The operable time calculation unit 703 specifies the operable time of the activity-related device based on the remaining battery level of the secondary battery 63, the estimated generated power, and the estimated power consumption (step S15). After the process of step S15 ends, the control unit 70 returns to the caller of the operable time specifying process.

Returning to the description of FIG.
The control unit 70 generates an operable time display screen based on the specified operable time (step S3). The display unit 41 displays the generated operable time display screen (step S4). After the process of step S4 ends, the control unit 70 ends a series of processes.

A. 3.2. Flowchart of Update Process FIG. 15 shows a flowchart of the operable time display process. The update unit 706 determines whether or not a predetermined time has elapsed since the previous execution of the processing from step S32 to step S40 (step S31). The predetermined time is, for example, one hour or one day.

  When the predetermined time has not elapsed since the previous execution of the iterative process 1 from step S32 to step S40 (step S31: No), the updating unit 706 executes the process of step S31 after a predetermined time has elapsed. When a predetermined time has elapsed since the previous execution of the processing from step S32 to step S40 (step S31: Yes), the update unit 706, for each type of activity, sleep, neglect, and normal operation, Repeat process 1 from step S33 to step S38 is performed (step S32, step S39).

  The updating unit 706 performs the repetition process 2 of step S34 for each power generation mechanism 50 (step S33, step S35). The updating unit 706 updates the generated power information 611 according to the equation (2) (step S34). After the repetition process 2 of step S34 for each power generation mechanism 50 ends, the update unit 706 performs the repetition process 3 of step S37 for each activity-related device (steps S36 and S38). The updating unit 706 updates the power consumption information 612 according to the equation (5) (step S37).

  After the repetition process 3 of step S37 for each activity-related device is completed and the repetition process 1 from step S33 to step S38 is completed for each type of activity, sleep, neglect, and normal operation, the update unit A step 706 determines whether a system termination instruction has been accepted (step S40). The system termination instruction is notified from an OS (Operating System) operating on the control unit 70 when the information processing apparatus 100 is shut down, for example.

  When the system termination instruction has not been received (step S40: No), the update unit 706 returns the process to step S31. On the other hand, when the system end instruction is received (step S40: Yes), the update unit 706 ends the series of processes.

A. 4). Effects of Embodiment As described above, the information processing apparatus 100 estimates the estimated generated power and estimated power consumption of the scheduled activity, and determines the remaining battery level of the secondary battery 63, the estimated generated power, and the estimated power consumption. Based on this, the operational time of the activity-related device is identified. The generated power and the power consumption vary depending on the scheduled activity, but the estimated generated power and the estimated power consumption reflect the influence of the activity scheduled to be performed by the user. Specifically, with respect to the generated power, when the planned activity is outdoor sports, the solar battery 51 can generate a large amount of power compared to during indoor sports, so the generated power varies between outdoor sports and indoor sports. Therefore, according to the present embodiment, it is possible to accurately estimate the operable time of the activity-related device as compared with the case where the activity scheduled to be performed by the user is not taken into consideration.

In addition, the display unit 41 includes a display unit 41 that displays an image indicating the operable time of the activity-related device. Thereby, the user can view the image displayed on the display unit 41 and grasp how much time activity can be performed without performing the charging operation. Furthermore, the user can predict the timing for performing the charging operation.
In general, since the operation time of the resturable device is limited, the user needs to charge frequently. When charging frequently, the user carries a device and a cable that can be charged, which causes a substantial burden on the user. In addition, a psychological burden that the secondary battery 63 may be completely discharged and the operation of the information processing apparatus 100 may stop occurs.
On the other hand, in this embodiment, since the timing which performs charge operation can be estimated, it becomes possible to suppress a user's psychological burden.

  In addition, the estimated power calculation unit 702 refers to the generated power information 611 to identify the estimated generated power corresponding to the scheduled activity, and refers to the power consumption information 612 to identify the estimated power consumption corresponding to the scheduled activity. . The types of activities include, for example, outdoor sports and indoor sports as described above. Since the solar cell 51 can generate a large amount of power as compared with indoor sports, the generated power fluctuates between outdoor sports and indoor sports. In terms of power consumption, in outdoor sports, the user may move much more than in indoor sports. Therefore, although the GPS module 22 needs to operate in outdoor sports, the GPS module 22 does not need to operate in indoor sports, so power consumption differs greatly between outdoor sports and indoor sports. Therefore, in this embodiment, since the generated power information 611 and the power consumption information 612 associated with the activity type are referred to, the operation-related device operation time can be accurately estimated as compared with the case where the activity type is not considered. It becomes possible to do.

Further, the update unit 706 updates the power consumption information 612 based on the power consumption of the activity-related device when the activity is performed. The power consumption information 612 reflects the history of power consumption of the activity-related device when the activity is performed. Thus, by specifying the estimated power consumption based on the power consumption history, it is possible to accurately estimate the operable time of the activity-related device as compared with the case where the power consumption history is not considered.
For example, when a user enters a tunnel while jogging, which is an example of outdoor sports, the GPS module 22 continues to search for satellites, so the consumption of the GPS module 22 is smaller than when the user does not enter the tunnel. Electric power increases. If the user has entered the tunnel during outdoor sports in the past and the planned activity is outdoor sports, the user is likely to enter the tunnel even when the planned activity is performed. Therefore, by specifying the estimated power consumption based on the power consumption information 612 reflecting whether or not a user has entered the tunnel, the estimated power consumption in the scheduled activity is also increased in the tunnel during the scheduled activity. Whether or not a user enters is reflected in. Therefore, it is possible to estimate the operable time of the activity-related device with higher accuracy.

  The update unit 706 updates the generated power information 611 based on the generated power of the power generation mechanism 50 when the activity is performed. Table t611 specifies the estimated generated power based on the power generated by the power generation mechanism 50 when the activity is performed, and therefore, compared with the case where the generated power of the power generation mechanism 50 is not considered when the activity is performed. It is possible to accurately estimate the device operable time. For example, regarding the biofuel cell 54 included in the power generation mechanism 50, the amount of lactic acid contained in the user's sweat varies from person to person, and the amount of lactic acid varies depending on the presence or absence of exercise habits. Therefore, by specifying the estimated generated power based on the generated power history of the power generation mechanism 50, it is possible to accurately estimate the operable time of the activity-related device as compared with the case where the generated power history is not considered. become.

  In addition, the acquisition unit 701 specifies a time zone in which the scheduled activity is performed from the activity information 613, and acquires weather information 614 indicating a weather forecast corresponding to the time zone. The estimated power calculation unit 702 estimates the change of the activity information 613 based on the acquired weather information 614, and calculates the estimated generated power and the estimated power consumption based on the estimated activity indicated by the estimated activity information 613 after the change. presume. In general, the user changes the actual activity according to the weather. For example, even if the user plans to perform outdoor sports, the user may perform indoor sports if the weather is raining. Therefore, in order to estimate the change of the scheduled activity based on the weather forecast according to the time zone when the user performs the scheduled activity, the operation time of the activity-related device is compared with the case where the change of the scheduled activity is not considered. It becomes possible to estimate with high accuracy.

  Further, the acquisition unit 701 acquires weather information 614 indicating a weather forecast according to the position measured by the GPS module 22. The estimated power calculation unit 702 estimates the change of the activity information 613 based on the acquired weather information 614, and calculates the estimated generated power and the estimated power consumption based on the estimated activity indicated by the estimated activity information 613 after the change. presume. In the present embodiment, it is assumed that the position where the user is active is the current position, and a weather forecast corresponding to the position measured by the GPS module 22 is acquired. Therefore, in order to estimate the change of the scheduled activity based on the weather forecast according to the current position where the user performs the scheduled activity, the operation-related device operation time is reduced as compared with the case where the change of the scheduled activity is not considered. It becomes possible to estimate with high accuracy.

  In addition, the operable time calculation unit 703 specifies a value obtained by dividing the remaining battery level of the secondary battery 63 by a value obtained by subtracting the estimated generated power from the estimated power consumption as the operable time of the activity-related device.

Two or more aspects arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other. In addition, about the element which an effect | action and a function are equivalent to embodiment in the modification illustrated below, the code | symbol referred by the above description is diverted and each detailed description is abbreviate | omitted suitably.

  In the embodiment, the acquisition unit 701 identifies the activity scheduled to be implemented in the future registered in the activity information 613 as the activity scheduled to be performed by the user, but is not limited thereto. For example, the acquisition unit 701 may refer to the activity of the user on the current day of the previous week registered in the activity information 613 and identify the current activity of the previous week as an activity scheduled to be performed today. .

  In each form mentioned above, generated electric power is not restricted to the electric power generation amount per unit time, but includes the electric power generation amount for a predetermined period. Similarly, power consumption is not limited to power consumption per unit time, but includes power consumption for a predetermined period.

In each of the above-described forms, it has been described that the generated power and the power consumption fluctuate depending on the type of the scheduled activity. For example, the generated power and the power consumption vary depending on the time zone and season of the scheduled activity. For example, when outdoor sports are performed in the daytime, the generated power indicated by High of the solar cell 51 shown in FIG. 7 is obtained. However, when outdoor sports are performed in the evening or at night, the solar cell shown in FIG. Only the generated power indicated by 51 Mid or Low can be obtained. In addition, the generated power of the solar cell 51 when outdoor sports are performed in the summer is larger than that when the outdoor sports are performed in the winter.
Further, it is assumed that the display unit 41 does not emit light, the information processing apparatus 100 has a front light or a backlight that irradiates the display unit 41 with light, and the display unit 41 is irradiated with light at night. In this case, it is not necessary to irradiate the display unit 41 with light when performing outdoor sports during the day, while it is necessary to irradiate the display unit 41 with light when performing outdoor sports at night. Therefore, the power consumption when the outdoor sport is performed at night is larger than that when the outdoor sport is performed in the daytime.
Therefore, in the modification, the estimated power calculation unit 702 may estimate the estimated generated power and the estimated power consumption based on the time zone or season of the scheduled activity.

  In each embodiment described above, it is assumed that the estimated power consumption and the estimated generated power in the scheduled activity are uniform for all times of the scheduled activity, but may vary depending on the time of the scheduled activity. For example, assume that the scheduled activity time is from 5 pm to 7 pm and the sunset time is 6 pm. Based on such assumptions, the estimated power calculation unit 702 estimates the estimated generated power from 5:00 pm to 6:00 pm using the generated power indicated by the Mid of the solar cell 51, and 6:00 pm to 7:00 pm The estimated generated power up to may be estimated using the generated power indicated by Low of the solar cell 51.

  In each embodiment described above, the information processing apparatus 100 includes the solar cell 51, the kinetic mechanism 52, the thermoelectric conversion device 53, and the biofuel cell 54 as the power generation mechanism 50. However, the information processing apparatus 100 may include one or more power generation mechanisms 50. . Similarly, although the activity-related devices have been described as the GPS module 22, the pulse sensor 21, the acceleration sensor 24, the atmospheric pressure sensor 23, the communication unit 30, and the display unit 41, the information processing apparatus 100 includes one or more activity-related devices. Just include the device. Furthermore, in each form mentioned above, although the information processing apparatus 100 contains 3 or more sensors called the GPS module 22, the acceleration sensor 24, and the pulse sensor 21, you may have 2 or less sensors.

  In each of the above embodiments, the GPS module 22 receives satellite signals from GPS satellites, but the information processing apparatus 100 may receive satellite signals from other satellites. For example, the information processing apparatus 100 may receive satellite signals from positioning satellites other than GPS satellites or positioning satellites other than GNSS. For example, the information processing apparatus 100 includes WAAS (Wide Area Augmentation System), EGNOS (European Geostationary-Satellite Navigation Overlay Service), QZSS (Quasi Zenith Satellite System), GLONASS (GLObal NAvigation Satellite System), GALILEO, BeiDou (BeiDou Navigation Satellite). Satellite signals may be received from satellites of one or more satellite positioning systems such as System).

  The present invention can also be understood as a computer program configured to cause the above-described information processing apparatus 100 to function as each unit of the above-described information processing apparatus 100 or a computer-readable recording medium that records the computer program. . The recording medium is, for example, a non-transitory recording medium, and may include any known recording medium such as a semiconductor recording medium and a magnetic recording medium in addition to an optical recording medium such as a CD-ROM. The present invention is also specified as a method for controlling the information processing apparatus 100 according to each aspect described above.

  Further, although the information processing apparatus 100 has been described as a re-stable device that is one of portable information devices, the present invention is not limited thereto. Examples of portable information devices other than the listable device include a mobile phone, a smartphone, and a tablet terminal.

  Further, the information processing apparatus 100 does not have to include the display unit 41. For example, the information processing apparatus 100 may transmit the operable time of the identified activity-related device to a mobile phone having a display unit 41, a smartphone topphone, a tablet terminal, or the like. Further, the information processing apparatus 100 may transmit the operable time of the activity-related device to a server in the cloud computing regardless of the presence or absence of the display unit 41.
