The portable information processing apparatus according to the present embodiment is a portable information processing apparatus that generates a walking rhythm for arriving at a destination by a scheduled time, as shown in FIG. , An input module 110, a stride calculation module 120, a remaining distance calculation module 130, a remaining time calculation module 140, a target speed calculation module 150, a walking cycle calculation module 160, a rhythm generation module 170, and a control module 180. Here, walking includes not only walking but also running.
The control module 180 controls each module in the portable information processing apparatus, and exchanges information between modules.

  The input module 110 is connected to the stride calculation module 120, the remaining distance calculation module 130, and the remaining time calculation module 140. Based on the user's operation on the touch panel, the user's height 102, destination 101, and scheduled arrival time 103, which is the scheduled time to reach the destination, are input. Then, the destination 101 is transferred to the remaining distance calculation module 130, the height 102 is transferred to the stride calculation module 120, and the scheduled arrival time 103 is transferred to the remaining time calculation module 140.

The stride calculation module 120 is connected to the input module 110 and the walking cycle calculation module 160. The user's stride is calculated using the user's height 102 input by the input module 110. Then, the calculated step length of the user is passed to the walking cycle calculation module 160.
Here, the following formula (1) is used as a calculation formula for calculating the stride from the height 102.
F = 0.26 × H + 0.31 (1)
F: stride, H: height, unit is m (meter)
This equation (1) is based on “Chan Ken Ryo, Yasutoshi Yoshinaga, Shouning: A Study on the Correlation between Height and Stride: Academic Report 45, Faculty of Agriculture, University of the Ryukyus, pp 149-155 (1998)”. The coefficient of equation (1) may be varied depending on the gender, age, etc. of the user.

The remaining distance calculation module 130 is connected to the input module 110 and the target speed calculation module 150 and has a GPS 135.
The GPS 135 measures the current position of the portable information processing apparatus. For example, longitude and latitude are measured using GPS.
The remaining distance calculation module 130 calculates the distance from the current position to the destination using the destination input by the input module 110 and the position measured by the GPS 135. Then, the calculated distance is passed to the target speed calculation module 150. For example, the distance on the map is calculated using GIS (Geographic Information System).

The clock module 145 measures the current time.
The remaining time calculation module 140 calculates the remaining time from the current time to the estimated arrival time using the estimated arrival time input by the input module 110 and the current time measured by the clock module 145. Specifically, the current time is subtracted from the estimated arrival time. That is, the time that can be spent on walking is calculated. Then, the calculated remaining time is passed to the target speed calculation module 150.

The target speed calculation module 150 is connected to the remaining distance calculation module 130, the remaining time calculation module 140, and the walking cycle calculation module 160. The walking speed to the destination is calculated using the distance calculated by the remaining distance calculating module 130 and the remaining time calculated by the remaining time calculating module 140. Then, the calculated walking speed is passed to the walking cycle calculation module 160.
Here, the following formula (2) is used as a calculation formula for calculating the walking speed.
V = L ÷ T (2) Formula V: Walking speed (m / s) to be targeted, L: Distance (m), T: Remaining time (s)

The walking cycle calculation module 160 is connected to the stride calculation module 120, the target speed calculation module 150, and the rhythm generation module 170. The walking period is calculated using the walking speed calculated by the target speed calculation module 150 and the user's step calculated by the step calculation module 120. Then, the calculated walking cycle is passed to the rhythm generation module 170.
Here, the following formula (3) is used as a calculation formula for calculating the walking cycle.
C = F ÷ V (3)
C: Walking cycle (s)

  The rhythm generation module 170 is connected to the walking cycle calculation module 160. The walking cycle calculated by the walking cycle calculation module 160 is used to generate a walking rhythm of the user.

As a specific example, sound that is periodically generated from a speaker (including earphones, etc.) (more specifically, a metronome sound, a shout) , Music, etc.), periodic vibration by a vibrator, light periodically generated from a lamp, images / moving images periodically displayed on a display, and the like.

FIG. 2 is a flowchart showing an example of processing for calculating a stride.
In step S202, the input module 110 inputs the height of the user. The input module 110 displays the height input screen 300 on the display of the portable information processing apparatus. FIG. 3 is an explanatory diagram showing a display example of the height input screen 300. The user inputs his / her height into the height input field 310 in the height input screen 300 using a key and a touch panel.
In step S204, the stride calculation module 120 calculates the stride using the above-described equation (1). Then, the calculated stride length is displayed on the height input screen 300.
In step S206, the stride calculation module 120 stores the stride in the stride table 400 in the internal memory. FIG. 4 is an explanatory diagram showing an example of the data structure of the stride table 400. The stride length table 400 has an input date / time column 410, a height column 420, and a stride length column 430. The input date / time column 410 stores the date / time when the input was performed. This is the current time measured by the clock module 145. The height column 420 stores the input height 102. The stride column 430 stores the calculated stride.
This process only needs to be performed once to generate a rhythm. From the second time onward, the stride table 400 may be referred to.

FIG. 5 is a flowchart showing an example of processing for generating a rhythm.
In step S502, the input module 110 inputs a destination. The input module 110 displays a destination / scheduled time input screen 600 on the display of the portable information processing apparatus. FIG. 6 is an explanatory diagram showing a display example of the destination / scheduled time input screen 600. The user touches the destination in the map in the destination / scheduled time input screen 600. The input module 110 detects the touch position and inputs a destination. The map is displayed using GIS. When the normal image button 624, the satellite image button 626, and the hybrid image 628 are selected by a user operation, a map corresponding to the buttons is displayed.
The input module 110 stores the destination in the walking cycle table 700 in the internal memory. FIG. 7 is an explanatory diagram showing an example of the data structure of the walking cycle table 700. The walking cycle table 700 has a destination position field 710, a current position field 720, a distance field 730, a scheduled arrival time field 740, a current time field 750, a remaining time field 760, a target speed field 770, and a walking period field 780. Yes. The input destination is stored in the destination position column 710.

In step S504, the input module 110 inputs the estimated arrival time. The user inputs the scheduled arrival time 103 into the instruction / scheduled time input field 610 in the destination / scheduled time input screen 600 using a key and a touch panel. The inputted scheduled arrival time is stored in the scheduled arrival time column 740 in the walking cycle table 700.
In step S506, the current location is detected by the GPS 135. This current location is stored in the current location column 720 of the walking cycle table 700.
In step S508, the remaining distance calculation module 130 calculates a distance using a map. Based on the GIS, the distance on the map from the destination input in step S502 and the current location detected in step S506 (the distance when the route from the current location to the destination is traced) is calculated. This distance is stored in the distance column 730 of the walking cycle table 700.
At this point, as shown in the example of FIG. 8, the destination point 810 (x mark) and the current point 820 (● mark) are displayed on the map in the map screen 800, and the distance display field 830 is displayed. Thereafter, it is assumed that the start button 622 is selected by a user operation.

In step S510, the remaining time calculation module 140 calculates the remaining time. That is, using the current time measured by the clock module 145 and the estimated arrival time input in step S504, the remaining time until the destination is reached is calculated. The current time is stored in the current time column 750 of the walking cycle table 700, and the remaining time is stored in the remaining time column 760.
In step S512, the target speed calculation module 150 calculates the target walking speed using the above-described equation (2). This target walking speed is stored in the target speed column 770 of the walking cycle table 700.
In step S514, the walking cycle calculation module 160 calculates the walking cycle using the above-described equation (3). This walking cycle is stored in the walking cycle column 780 of the walking cycle table 700.
In step S516, the rhythm generation module 170 generates a rhythm using the walking cycle. Thereafter, the user walks in accordance with the rhythm generated by the portable information processing apparatus. As a result, the destination is reached by the scheduled arrival time.
In addition, by repeating the processes in and after step S506 at a constant cycle, a rhythm at that time can be generated. That is, after the rhythm is generated by the first processing from step S506 to step S516, the processing by the GPS 135, the remaining distance calculation module 130, the remaining time calculation module 140, the target speed calculation module 150, and the walking cycle calculation module 160 is performed. The rhythm generation module 170 generates a rhythm of walking at that time. As a result, a faster rhythm is engraved when walking at a slower tempo than the generated rhythm, and a slower rhythm is engraved when walking at a faster tempo.

<Second Embodiment>
Even when walking according to the rhythm generated by the portable information processing apparatus according to the first embodiment described above, if an accident occurs (for example, a traffic light, waiting at a railroad crossing, talking by a friend) The arrival time must be changed. The second embodiment deals with such a case.
The module configuration of the second embodiment is equivalent to the module configuration of the first embodiment. However, the input module 110 displays a correction button on the map screen 800 in addition to the function in the first embodiment, detects whether the correction button has been selected by the user's operation, and detects the destination. Correct the estimated time to reach.

FIG. 9 is a flowchart illustrating a processing example for correcting the estimated arrival time.
In step S902, the input module 110 determines whether the correction button has been pressed. If it has been pressed, the process proceeds to step S904; otherwise, the process proceeds to step S999.
In step S904, the input module 110 corrects the estimated arrival time according to the user's operation. FIG. 10 is an explanatory diagram showing a display example of the map screen 1000 after the correction button is pressed. Since the user is in the middle of walking, the current location has moved from the departure location 1025 to the current location 1020, and the remaining distance in the distance display column 1030 is also at that time. The user inputs the corrected estimated arrival time 103 into the estimated arrival time correction field 1040 in the map screen 1000 using a key and a touch panel. The corrected estimated arrival time is stored in the estimated arrival time column 740 in the walking cycle table 700.
In step S906, the process proceeds to step S506 shown in the example of FIG. That is, the rhythm generation module 170 performs processing by the GPS 135, the remaining distance calculation module 130, the remaining time calculation module 140, the target speed calculation module 150, and the walking cycle calculation module 160 based on the estimated arrival time after correction. Generate a walking rhythm for arriving at the destination at the corrected estimated arrival time.

<Third Embodiment>
The rhythm generated by the portable information processing apparatus according to the first or second embodiment described above is generated depending on the remaining time until the scheduled arrival time and the distance to the destination. There is a case. In addition, even when the above-mentioned accident occurs and the scheduled arrival time is not changed during walking, the rhythm may be difficult to walk. The third embodiment deals with such a case.
The module configuration of the third embodiment is equivalent to the module configuration of the first or second embodiment. However, when the walking cycle calculation module 160 compares the calculated walking cycle with a predetermined value in addition to the functions in the first or second embodiment, the walking cycle can be difficult to walk. Prompts the user to correct the scheduled time to reach the destination.

FIG. 11 is a flowchart illustrating an example of a process for prompting correction of the estimated arrival time.
In step S1102, the walking cycle calculation module 160 determines whether or not the walking cycle ≧ limit value. If the walking cycle ≧ limit value, the process proceeds to step S1104. Otherwise, the process proceeds to step S1199. The limit value refers to a walking cycle that can be difficult to walk above that value, and is a predetermined value. The walking speed of a general person may be set, the walking speed input by the user may be set, or the highest actual walking speed of the user may be set. May be.
In step S1104, the walking cycle calculation module 160 prompts the correction of the scheduled arrival time. In other words, a message that prompts the user to correct the arrival time later is displayed on the display.
In step S1106, the process proceeds to step S902 shown in the example of FIG.

  In this example, the limit value is the fastest walking cycle, but it may be compared with the limit value of the slowest walking cycle when walking. In other words, if the rhythm is too slow, it is urged to correct it at an earlier scheduled arrival time. In that case, in step S1102, the walking cycle calculation module 160 determines whether or not the walking cycle ≦ limit value. If the walking cycle ≦ limit value, the process proceeds to step S1104. Otherwise, the process proceeds to step S1199. In step S1104, a message that prompts the user to correct the scheduled arrival time is displayed on the display.
