[Technical Field]

[0001] The present invention relates to a walking route guidance system, a walking route guidance method, and a walking route guidance program for providing guidance on walking routes. [Background technology]

[0002] In today's rapidly aging society, it is desirable for the elderly to be able to live healthy and independent lives. The Ministry of Health, Labor and Welfare recommends that elderly people walk for at least 40 minutes a day as physical activity to maintain their health.

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings. A walking route guidance system according to the present invention provides walking route guidance that corresponds to the walking ability of an individual user.

[0020] A walking route guidance system 1 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of the walking route guidance system 1 according to this embodiment.

[0021] As shown in FIG. 1, the walking route guidance system 1 includes a processing device 10, a measuring device 30, a display device 41, and an input device 42. The processing device 10, the measuring device 30, the display device 41, and the input device 42 are integrated with the functions of each device and configured as a single mobile terminal such as a smartphone or tablet owned by a user. Alternatively, all or some of the processing device 10, the measuring device 30, the display device 41, and the input device 42 may be configured as separate devices and connected via a computer network such as the Internet or a wide area network (WAN). For example, the processing device 10 may be configured as a server computer, and the measuring device 30, the display device 41, and the input device 42 may be configured as mobile terminals such as a smartphone or tablet owned by a user.

[0022] The measuring device 30 is a device that measures acceleration data and position information of a user while walking. The measuring device 30 includes an acceleration sensor 31 for acquiring acceleration data and a position measuring device 32 for acquiring position information. The position measuring device 32 is, for example, a GPS (Global Positioning System). The measuring device 30 is configured as a portable terminal that the user can hold while walking, and is, for example, a portable terminal such as a smartphone or tablet equipped with an acceleration sensor and GPS, or a GPS equipped with an acceleration sensor.

[0023] The acceleration sensor 31 and the position measuring device 32 measure the user's acceleration data and position information at predetermined time intervals (for example, every one to several seconds) while the user is walking. The position information is measured by the position measuring device 32 receiving a GPS signal. Specifically, the acceleration sensor 31 and the position measuring device 32 measure the user's acceleration data and position information from the time the user starts up the walking route guidance system 1 to go walking until the time the user finishes walking and ends the walking route guidance system 1.

[0024] The display device 41 is a device that displays walking route guidance to the user. The display device 41 is, for example, a smartphone display. The input device 42 is a device that inputs user information and walking conditions desired by the user. The input device 42 is, for example, a touch panel, a microphone, a keyboard, a mouse, etc.

[0025] The processing device 10 acquires acceleration data and position information of a user while walking, and creates walking route guidance based on the acquired acceleration data and position information. The processing device 10 includes a walking data storage unit 11, a gait value calculation unit 12, a walking condition acquisition unit 13, a route guidance creation unit 14, a display control unit 15, an initial gait data storage unit 16, an initial flat ground gait value calculation unit 17, an initial terrain-specific gait value estimation unit 18, an evaluation unit 19, a memory unit 21, and a control unit 22. The processing device 10 is, for example, a computer such as a smartphone, a tablet, a microcomputer, a personal computer, or a server computer.

[0026] The gait value calculation unit 12 calculates a terrain-specific individual gait value that indicates the user's walking ability for each terrain based on acceleration data and position information acquired while walking according to route guidance. Specifically, the gait value calculation unit 12 acquires from the measurement device 30 acceleration data and position information measured by the measurement device 30 while walking according to route guidance. At this time, the acceleration data and position information are associated with each other and are acquired in association with date and time information indicating the date and time of measurement. Then, after walking according to route guidance is completed, the individual gait value is calculated based on the acquired acceleration data and position information. Here, terrain refers to the characteristics of the road on which the user walks, such as flat ground, slopes, and stairs. In this embodiment, flat ground refers to a road with a gradient between -3% and 3%. Slopes and stairs are further divided into uphill and downhill sections and by gradient. The individual gait value is the walking speed, rest interval, and rest time per unit time (e.g., 1 second). The rest interval is the interval between breaks, indicating the number of minutes of walking before and after a break. The rest time indicates how many minutes of rest the person took before starting to walk, that is, the time from when the person stopped walking until when the person started walking again.

[0027] The walking data storage unit 11 stores the individual walking values ​​calculated by the walking data calculation unit 12. Specifically, the walking data storage unit 11 stores the individual walking values ​​calculated by the walking value calculation unit 12 together with the date information of the walking performed when the individual walking values ​​were calculated.

[0028] The walking condition acquisition unit 13 acquires the walking conditions desired by the user inputted by the input device 42. The walking conditions include, for example, a start point, a finish point, and a walking time.

[0029] The walking conditions may include a walking load. The walking load can be input by selecting, for example, an easy mode with a low load, a normal mode with an average load, or a hard mode with a high load. Here, the easy mode, normal mode, and hard mode are determined based on the user's walking speed on flat ground. A terrain where the walking speed is the same as or faster than the walking speed on flat ground is defined as a normal road, and a terrain where the walking speed is slower than the walking speed on flat ground is defined as a hard road. The mode is determined based on the ratio of normal roads to hard roads. Since different users have different perceptions of the load, such as walking uphill or downhill, the load is determined based on the walking speed on flat ground. In this embodiment, the easy mode is determined when the time spent walking on hard roads is less than 30% of the total walking time of the walking route, the hard mode is determined when the time spent walking on hard roads is 50% or more of the total walking time of the walking route, and all other cases are defined as normal mode.

[0030] The walking conditions may also include the user's physical condition on the day of walking. The user's physical condition can be input, for example, by selecting at least normal or poor condition, preferably by selecting good, normal, or poor condition. When the walking conditions include the user's physical condition, the route guidance creation unit 14, which will be described later, creates route guidance by adjusting the individual walking value and the like in accordance with the user's physical condition included in the walking conditions. Specifically, at least one of the walking speed, rest interval, and rest time can be adjusted, for example, by increasing the walking speed by 10% when the user is in good condition and decreasing the walking speed by 10% when the user is in poor condition.

[0031] Furthermore, walking conditions may include the user's desired route (e.g., a different route from the previous day), places the user wants to pass through (e.g., places with seasonal flowers, places with people or animals the user wants to meet, etc.), etc.

[0032] The route guidance creation unit 14 creates walking route guidance corresponding to the walking conditions acquired by the walking condition acquisition unit 13 based on the user's most recent personal walking value acquired from the walking data storage unit 11. The most recent refers to the day closest to the day of walking and the day up to several days before the day closest to the day of walking. The acquired personal walking value may be for one day or for several days.

[0033] Specifically, the route guidance creation unit 14 calculates a range within which the user can travel from the start point to the goal point within the walking time desired by the user, based on the user's personal walking value, particularly walking speed, with the start point and goal point as the center. More specifically, in the case of walking, the start point and goal point are basically the same as the user's home, so the radius within which the user can travel from the start point to the goal point within the walking time desired by the user, based on the user's walking speed, is calculated. The route guidance creation unit 14 creates walking route guidance within the calculated range that provides the user with the walking load desired by the user. At this time, the route guidance creation unit 14 creates walking route guidance by excluding roads that are deemed difficult to walk based on the user's walking ability (e.g., steep uphill and downhill slopes, etc.). Roads deemed difficult to walk include, for example, roads where the user's personal walking value for each terrain is too slow or roads with too many rest intervals.

[0034] The route guidance creation unit 14 creates walking route guidance by not including rest time in walking time, but by indicating the rest intervals and rest times required by the user for each terrain acquired from the walking data storage unit 11 in the walking route guidance. That is, the created walking route guidance includes rest points for each rest interval, and the rest times required by the user at each rest point. Various walking routes can be used, such as a circular route that starts from a starting point, makes a full circle, and returns to a goal point, or a return route that starts from a starting point, turns around at a certain point, and returns to the goal point. However, a circular route is preferred. Furthermore, if a user's desired route or a place the user wants to pass through is specified as a walking condition, the route guidance creation unit 14 creates walking route guidance that includes the user's desired route or the place the user wants to pass through. In addition, when the walking conditions include the user's physical condition, the route guidance creation unit 14 can create walking route guidance that adjusts at least one of the walking time, walking distance, and proportion of hard roads so as to increase the walking load when the user is in good physical condition and reduce the walking load when the user is in poor physical condition.

[0035] The display control unit 15 displays the route guidance corresponding to the user, which has been created by the route guidance creation unit 14, on a display device 41 possessed by the user.

[0036] The initial walking data storage unit 16 acquires and stores acceleration data and position information acquired by the user walking on flat ground for a certain period of time when the walking route guidance system 1 is used for the first time. The acceleration data and position information to be stored are acquired from the measurement device 30 as acceleration data and position information measured by the measurement device 30 while the user is walking on flat ground for a certain period of time. The acceleration data and position information are associated with each other and are also associated with date and time information indicating the date and time of measurement when they are stored.

[0037] The initial flat ground walking value calculation unit 17 calculates an initial flat ground walking value that indicates the user's initial flat ground walking ability based on the acceleration data and position information acquired from the initial walking data storage unit 16. The initial flat ground walking value is the walking speed, rest interval, and rest time per unit time when walking on the initial flat ground. The initial flat ground walking value calculation unit 17 calculates the initial flat ground walking value using the same method as the walking value calculation unit 12 described later.

[0038] The initial terrain-specific gait value estimating unit 18 estimates the initial terrain-specific gait value based on the initial flat ground gait value calculated by the initial flat ground gait value calculating unit 17 .

[0039] The evaluation unit 19 evaluates the user's walking ability. The walking data storage unit 11 stores personal walking values ​​for the past few months when the user walked using the walking route guidance system 1 in the past for each user. The evaluation unit 19 acquires the personal walking values ​​from the walking data storage unit 11 and evaluates the user's walking ability by comparing the personal walking values. Specifically, for example, the evaluation unit 19 compares the current personal walking values ​​with those from three months ago, determines whether walking speed, rest interval, and rest time have improved or decreased by terrain, and comprehensively assesses each change to evaluate whether the user's walking ability has improved or decreased. By using the personal walking values ​​by terrain for evaluation, an accurate evaluation of the user's walking ability can be performed, taking into account walking ability on slopes such as hills or stairs.

[0040] The evaluation unit 19 can also evaluate the walking ability of the user to be evaluated by comparing the personal walking value of the user to be evaluated with machine-learned data of the personal walking values ​​of all users who use the walking route guidance system 1. The results of the evaluation by the evaluation unit 19 are displayed on the display device 41 by the control unit 22, allowing the user to check their own walking ability.

[0041] The storage unit 21 stores various information, data, programs, etc. The storage unit 21 is composed of a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 21 stores estimation databases 51, 52, and 53 (see FIGS. 5 to 7) for estimating walking speed, rest intervals, and rest times for each terrain, as described below, as well as a walking route guidance program for guiding walking routes.

[0042] The control unit 22 is configured by a processor such as a CPU (Central Processing Unit). The control unit 22 executes a program to control the operations of the walking data storage unit 11, walking value calculation unit 12, walking condition acquisition unit 13, route guidance creation unit 14, display control unit 15, initial walking data storage unit 16, initial flat ground walking value calculation unit 17, initial terrain-specific walking value estimation unit 18, evaluation unit 19, and memory unit 21.

[0043] Next, with reference to FIGS. 2 to 7, a walking route guidance method for creating walking route guidance based on the walking route guidance system 1 will be described. The walking route guidance method acquires acceleration data and position information of a user while walking, and creates walking route guidance based on the acquired acceleration data and position information. FIGS. 2 and 3 are flowcharts showing the walking route guidance method according to this embodiment. FIG. 4 is a flowchart showing a method for calculating rest intervals and rest times in the walking route guidance system 1 according to this embodiment. FIG. 5 is a diagram showing an example of a terrain-specific walking speed estimation database for estimating walking speeds for each terrain used in the present invention. FIG. 6 is a diagram showing an example of a terrain-specific rest interval estimation database for estimating rest intervals for each terrain used in the present invention. FIG. 7 is a diagram showing an example of a terrain-specific rest time estimation database for estimating rest times for each terrain used in the present invention. Each process of the walking route guidance method is executed by a walking route guidance program stored in the memory unit 21 of the processing device 10.

[0044] 2, when the user starts the walking route guidance system 1, the control unit 22 first checks whether acceleration data and position information are stored in the initial walking data storage unit 16 (S10). If acceleration data and position information are stored in the initial walking data storage unit 16 (Yes in S10), the control unit 22 checks whether the personal walking value or the initial walking value is stored in the walking data storage unit 11 (S12).

[0045] If the walking data storage unit 11 has an individual walking value or an initial walking value (Yes in S12), the route guidance generation unit 14 acquires the most recent individual walking value or initial walking value (hereinafter simply referred to as "individual walking value") from among the individual walking values ​​or initial walking values ​​stored in the walking data storage unit 11 (S14). The individual walking value is associated with date information on when the individual walking value was calculated, and the route guidance generation unit 14 acquires the most recent individual walking value based on the date information.

[0046] Meanwhile, the control unit 22 displays a screen on the display device 41 for inputting walking conditions, and the user inputs the walking conditions using the input device 42. The input walking conditions are acquired by the walking condition acquisition unit 13 (S16). The acquired walking conditions are transmitted to the route guidance creation unit 14. The route guidance creation unit 14 calculates a range in which the user can travel from the start point to the goal point in the walking time desired by the user based on the walking speed of the personal walking value acquired from the walking data storage unit 11, and executes a route guidance creation step to create walking route guidance (S18). At this time, the route guidance creation unit 14 determines whether or not there are any roads that are difficult to walk within the range in which the user can travel based on the user's walking ability, and if there are any roads that are difficult to walk, it excludes the roads that are difficult to walk, and creates walking route guidance within that range that includes various terrains and provides the user with the walking load desired (S18).

[0047] The created walking route guidance is transmitted to the display control unit 15, which then displays the route guidance on the display device 41 held by the user (S20). The user walks while referring to the walking route guidance displayed on the display device 41. While the user is walking, the measurement device 30 measures acceleration data and position information at predetermined time intervals, and the acceleration data and position information measured by the measurement device 30 are acquired by the control unit 22 (S22).

[0048] The control unit 22 checks whether there is a change in the walking situation during walking (S24), and if there is a change in the walking situation (change in S24), causes the route guidance creation unit 14 to create walking route guidance according to the change in the walking situation. On the other hand, if there is no change in the walking situation (no change in S24), the walking route guidance created by the route guidance creation unit 14 continues to be displayed on the user's display device 41, and the measurement device 30 acquires acceleration data and position information.

[0049] Specifically, the control unit 22 determines that there is a change in the walking situation when there is a change in the rest time, the rest interval, or the route. Here, a change in the route occurs when, for example, there is a sudden need to move to the goal point while walking, when the user deviates from the indicated walking route guidance due to construction work or the like that is not reflected on the map, or when the walking speed is too fast or slow to walk the set walking time according to the indicated walking route guidance.

[0050] The control unit 22 acquires the position information measured by the measuring device 30 at predetermined intervals while the user is walking, and the date and time information when the position information was measured, and determines a change in the walking situation from the difference between the position information and date and time information planned in the walking route guidance shown by the route guidance creation unit 14 and the actual position information and date and time information. If the user suddenly needs to move to the goal point while walking, the control unit 22 detects that the user has selected an icon to select when wishing to return home, which is displayed together with the walking route guidance on the display device 41 held by the user, and determines a change in the walking situation.

[0051] If the rest time and / or rest interval changes during walking, the route guidance creation unit 14 creates new walking route guidance that reflects the changes in the rest time and / or rest interval. For example, if the user takes a longer rest time than expected while climbing a steep uphill slope, the route guidance creation unit 14 creates new walking route guidance that shortens the rest time at the next rest point. Also, if the user takes a break while climbing a steep uphill slope, the route guidance creation unit 14 creates new walking route guidance that starts from the rest point and allows the user to take a rest again at a rest interval based on the user's personal walking value.

[0052] If the user wishes to move to the goal point via the shortest route during walking due to a change in physical condition or an urgent matter, the route guidance creation unit 14 acquires the user's current location using the GPS function of the position measuring device 32 of the measuring device 30, and creates walking route guidance that has been modified to allow the user to move to the goal point via the shortest route from the user's current location.

[0053] When the walking route guidance is deviated from, the walking route guidance is created again based on the walking time remaining after subtracting the walking time taken until the change in the walking route occurs from the walking time set in the walking condition acquisition unit 13 and the walking load set in the walking condition acquisition unit 13.

[0054] In the case of a route change due to a change in walking speed, for example, if the position information and date and time information scheduled in the walking route guidance shown by the route guidance creation unit 14 deviates from the actual position information and date and time information by more than a certain amount, the walking route guidance is regenerated based on the walking time remaining after subtracting the walking time taken up to the point where the deviation between the position information and date and time information became more than a certain amount from the walking time set by the walking condition acquisition unit 13, and the walking load set by the walking condition acquisition unit 13. Also, if the position information and date and time information scheduled in the walking route guidance shown by the route guidance creation unit 14 starting from a rest point where about 1 / 3 or 1 / 2 of the entire walking route has been walked deviates from the actual position information and date and time information, the walking route guidance is regenerated based on the walking time remaining after subtracting the walking time taken up to the point where the deviation between the position information and date and time information became more than a certain amount from the walking time set by the walking condition acquisition unit 13, and the walking load set by the walking condition acquisition unit 13.

[0055] When the user finishes walking according to the walking route guidance, the acceleration data and position information acquired by the control unit 22 are transmitted to the walking value calculation unit 12, and the walking value calculation unit 12 executes a walking value calculation step to calculate an individual walking value that indicates the user's walking ability for each terrain based on the acquired acceleration data and position information (S26).

[0056] Specifically, the gait value calculation unit 12 acquires a map of the area where the user walked from map information available on the network via a computer network based on the acquired location information. Then, the gait value calculation unit 12 acquires topographical information of the path the user walked from the acquired map, such as whether the path was flat and the gradient of the uphill or downhill slope. The acquired topographical information is associated with the location information. Thus, the gait value calculation unit 12 stores the acceleration data and location information measured at predetermined intervals, the date and time information about the date and time of the measurements, and the topographical information in a state where they are associated with each other.

[0057] The gait value calculation unit 12 calculates the walking speed per unit time for each terrain by integrating the acceleration data for each terrain based on the measurement interval of the acceleration data, which can be obtained from the date and time information. The gait value calculation unit 12 also analyzes the acceleration change caused by the body swaying due to walking from the acceleration data for each terrain, detects the movement of each step, and calculates the number of steps per unit time. The calculated walking speed and number of steps per unit time are associated with the location information, date and time information, and terrain information associated with the acceleration data used for the calculation.

[0058] Next, as shown in FIG. 4, the walking value calculation unit 12 obtains the number of steps every 5 seconds from the calculated number of steps per unit time (S70), and determines whether the number of steps has stopped based on whether the number of steps has changed (S72). If the number of steps has not stopped (No in S72), the number of steps every 5 seconds is obtained again (S70). If the number of steps has stopped (Yes in S72), location information at the time the number of steps stopped is obtained (S74). The obtained location information is compared with a map, and it is determined whether there is a traffic situation at the location where the number of steps stopped that requires the user to stop walking, such as a crosswalk or railroad crossing (S76). If there is a traffic situation that requires the user to stop walking (Yes in S76), the user is not considered to be taking a break (S78).

[0059] On the other hand, if there is no traffic situation that requires the user to stop walking (No in S76), the gait value calculation unit 12 considers this a break and calculates a rest interval from the date and time information when the step count stopped and the date and time information when the user started walking (S80). Thereafter, when the gait value calculation unit 12 detects that the number of steps per unit time has changed and that walking has started, it calculates a rest time from the date and time information when the step count started and the date and time information when the step count stopped (S82). The calculated rest interval and rest time are classified by terrain based on the terrain information associated with the number of steps per unit time used for the calculation. By repeating this process, the gait value calculation unit 12 calculates an individual gait value for each terrain from the user's acceleration data and position information. Note that in this embodiment, the number of steps is calculated every 5 seconds, but this time is not limited to 5 seconds. However, since a too long interval makes it difficult to accurately determine the rest interval and rest time, it is preferable to calculate at intervals of 10 seconds or less. Alternatively, walking speed may be used instead of the number of steps, and it may be determined from the walking speed whether walking has stopped.

[0060] The calculated individual walking value is transmitted to the walking data storage unit 11 together with the date information on when the individual walking value was calculated, and is stored in the walking data storage unit 11 (S28). Then, each process in the walking route guidance method is completed.

[0061] When the walking route guidance system 1 is used for the first time and there is no acceleration data or position information in the initial walking data storage unit 16 (No in S10), the control unit 22 acquires position information of the user's current location from the position measuring device 32 of the measuring device 30 held by the user (S30), as shown in Fig. 3. Furthermore, based on the acquired position information of the current location, the control unit 22 acquires a map of the area around the current location from map information present on the network, and acquires information on flat areas around the current location from the map (S32).

[0062] The information about flat ground around the current location acquired by the control unit 22 is transmitted to the display control unit 15, and the display control unit 15 displays the flat ground information on the display device 41 held by the user (S34). The user walks on the flat ground for a certain period of time, referring to the flat ground information displayed on the display device 41. While the user is walking, the measurement device 30 measures acceleration data and position information at predetermined time intervals. The acceleration data and position information measured by the measurement device 30 are acquired by the control unit 22 (S36) and stored in the initial walking data storage unit 16 (S38).

[0063] When the walking route guidance system 1 is used for the second time, if the initial walking data storage unit 16 has acceleration data and position information, but the walking data storage unit 11 does not have the personal walking value and initial walking value (No in S12), as shown in Fig. 2, the initial flat ground walking value calculation unit 17 acquires the user's flat ground acceleration data and position information acquired at the time of first use from the initial walking data storage unit 16 (S50). The initial flat ground walking value calculation unit 17 calculates an initial flat ground walking value that indicates the user's initial walking ability on flat ground based on the acquired flat ground acceleration data and position information (S52). The calculated initial flat ground walking value is transmitted to the initial terrain-specific walking value estimation unit 18.

[0064] The initial terrain-specific gait value estimation unit 18 estimates the user's terrain-specific initial gait value based on the acquired initial flat ground gait value (S54). Specifically, the storage unit 21 stores a terrain-specific walking speed estimation database 51, a terrain-specific rest interval estimation database 52, and a terrain-specific rest time estimation database 53, which indicate estimated values ​​of walking speed, rest interval, and rest time on uphill and downhill roads by gradient based on the walking speed, rest interval, and rest time on flat ground, as shown in FIGS. 5 to 7. The initial terrain-specific gait value estimation unit 18 estimates the terrain-specific initial gait value based on the estimation databases 51, 52, and 53 previously prepared in the storage unit 21. The terrain-specific initial rest time is estimated based on the initial walking speed and rest interval on flat ground as well. That is, for a user whose initial walking speed on flat ground is 80 meters per minute and belongs to category A in terrain-specific walking speed estimation database 51, whose initial rest interval on flat ground is 6 minutes and belongs to category e in terrain-specific rest interval estimation database 52, based on the initial walking speed and rest interval on flat ground, the user falls into category Ae in terrain-specific rest time estimation database 53. If the initial rest time on flat ground is 2 minutes, the initial rest time for each terrain is estimated by referring to category Ae-ii in terrain-specific rest time estimation database 53.

[0065] Each of the estimation databases 51, 52, and 53 is constructed by machine learning acceleration data and position information actually acquired from multiple users who have previously walked walking routes including various terrains using the walking route guidance system 1. Note that in Figures 5 to 7, the gradient is shown divided into four stages, with a gentle gradient being designated as gradient 1 and a steep gradient being designated as gradient 4, but the stages based on gradient are not limited to four stages. Also, although Figures 5 to 7 do not show estimated values ​​for walking speed, rest interval, and rest time for stairs, estimated values ​​for walking speed, rest interval, and rest time for stairs may also be shown.

[0066] The estimated initial walking values ​​for each terrain are transmitted to the walking data storage unit 11 and the route guidance creation unit 14, and are stored in the walking data storage unit 11 (S56). Thereafter, similar to the walking route guidance method described above, the walking condition acquisition unit 13 acquires the input walking conditions (S16), and the route guidance creation unit 14 executes a route guidance creation step to create walking route guidance using the initial walking values ​​for each terrain acquired from the initial terrain walking value estimation unit 18 (S18).

[0067] The created walking route guidance is transmitted to the display control unit 15, which then displays the route guidance on the display device 41 held by the user (S20). The user walks while referring to the walking route guidance displayed on the display device 41. While the user is walking, the measurement device 30 measures acceleration data and position information at predetermined time intervals. The acceleration data and position information measured by the measurement device 30 are acquired by the control unit 22 (S22), and the gait value calculation unit 12 calculates the personal gait value (S26), which is then stored in the gait data storage unit 11 (S28). [Example]

[0068] Next, the walking route guidance system 1 according to the above embodiment will be specifically described using examples.

[0069] [Example 1] Example 1 will be described with reference to Fig. 8 and Fig. 9. Fig. 8 and Fig. 9 are diagrams showing walking route guidance created in Example 1. Fig. 8 shows walking route guidance for user 1, and Fig. 9 shows walking route guidance for user 2. In Fig. 8 and Fig. 9, normal roads for the user are shown with thin lines, hard roads are shown with thick lines, flat roads are shown as ±0, uphill roads are shown as +1 to +4, and downhill roads are shown as -1 to -4 depending on the gradient level.

[0070] In Example 1, assuming User 1 who is in his early 60s and has an exercise habit and User 2 who is in his late 70s and does not have an exercise habit, walking route guidance is created using the walking route guidance system 1 of the above embodiment. Both User 1 and User 2 use the walking route guidance system 1, and the personal walking values ​​of each user who walked according to past route guidance are stored in the walking data storage unit 11.

[0071] Using the walking route guidance system 1 of the above embodiment, the most recent personal walking values ​​of each user stored in the walking data storage unit 11 are as shown in Tables 1 and 2. Table 1 shows the personal walking values ​​of user 1, and Table 2 shows the personal walking values ​​of user 2. As shown in Table 2, user 2 has difficulty traveling uphill and downhill slopes with a gradient of 4, i.e., steep uphill and downhill slopes, and is therefore excluded from route guidance, so no walking speed or rest interval is set.

[0072] [Table 1]

[0073] [Table 2]

[0074] User 1 will have a rest period of 2 minutes regardless of the terrain, and a rest period of 5 minutes once every three times. User 2 will have a rest period of 1 minute regardless of the terrain. 2 minutes The walking route guidance is created for both User 1 and User 2, with the starting point S and goal point G set to the same location and the walking time set to 40 minutes in normal mode.

[0075] For user 1, Table 1 shows that the walking speed on flat roads is 80 meters per minute, and the walking speed on downhill slopes with a gradient of 1 and downhill slopes with a gradient of 2 is the same as or faster than the walking speed on flat roads. Therefore, flat roads, downhill slopes with a gradient of 1, and downhill slopes with a gradient of 2 are considered normal roads. Other roads, such as uphill slopes with a gradient of 1, uphill slopes with a gradient of 2, uphill slopes with a gradient of 3, downhill slopes with a gradient of 3, uphill slopes with a gradient of 4, and downhill slopes with a gradient of 4, are considered hard roads. To create route guidance for a 40-minute walk in normal mode, the route guidance creation unit 14 creates walking route guidance such that the walking time on normal roads is 20 to 28 minutes and the walking time on hard roads is 12 to 20 minutes. An example of the created walking route guidance is shown in Figure 8. Note that various walking route guidance can be created even under the same walking conditions, so Figure 8 is merely an example.

[0076] As shown in Figure 8, the walking time for user 1 on a normal road is 24 minutes, and the walking time for user 1 on a hard road is 16 minutes, indicating that route guidance for a 40-minute walk in normal mode has been created. Table 1 also shows that user 1 is supposed to take a break after walking for 7 minutes on flat roads and downhill slopes with a gradient of 1, and that a walking route guidance has been created with rest point R indicated at the point where the break should be taken according to Table 1. When walking on roads with different rest intervals (between R4 and R5, and between R5 and R6 in Figure 8), the rest interval is determined based on the ratio of the walking distance between the previous and next rest breaks (walking speed × rest interval), calculated from the walking speed and rest interval for each terrain category, to the distance walked on the walking route.

[0077] For user 2, Table 2 shows that the walking speed on flat roads is 55 meters per minute, and the walking speed on uphill slopes with a gradient of 1, downhill slopes with a gradient of 1, and downhill slopes with a gradient of 2 is the same as on flat roads. Therefore, flat roads, uphill slopes with a gradient of 1, downhill slopes with a gradient of 1, and downhill slopes with a gradient of 2 are considered normal roads. The other roads, uphill slopes with a gradient of 2, uphill slopes with a gradient of 3, and downhill slopes with a gradient of 3, are considered hard roads. The uphill slopes with a gradient of 4 and downhill slopes with a gradient of 4 are excluded because they are difficult for user 2 to walk on. To create route guidance for a 40-minute walk in normal mode, the route guidance creation unit 14 creates walking route guidance so that the walking time on normal roads is 20 to 28 minutes and the walking time on hard roads is 12 to 20 minutes. An example of the created walking route guidance is shown in Figure 9. Note that, as with user 1, various walking route guidance can be created even under the same walking conditions, so Figure 9 is merely an example.

[0078] As shown in Figure 9, the walking time for User 2 on a normal road is 25 minutes, and the walking time for User 2 on a hard road is 15 minutes, indicating that route guidance for a 40-minute walk in normal mode has been created. It can be seen that the walking route guidance created does not include any uphill or downhill slopes with a gradient of 4, which would be difficult for User 2 to walk on. Furthermore, Table 2 indicates that User 2 takes a break after walking for 4 minutes on flat roads, uphill slopes with a gradient of 1, and downhill slopes with a gradient of 1, and that the walking route guidance created according to Table 2 indicates rest points R at locations where rest should be taken. It can also be seen that even when roads with similar gradients continue (between R2 and R4, and between R7 and R9 in Figure 9), rest points R are provided at each rest interval required for that gradient.

[0079] Comparing Figures 8 and 9, it can be seen that even when walking for 40 minutes in the same normal mode, the walking route guidance differs depending on the user's personal walking value, and walking route guidance is created to suit the user's walking ability.

[0080] [Example 2] Example 2 will be described with reference to Figures 8 and 10. Figure 10 is a diagram showing walking route guidance created in Example 2. In Figure 10, normal roads for the user are shown with thin lines, hard roads are shown with thick lines, flat roads are shown as ±0, uphill roads are shown as +1 to +4, and downhill roads are shown as -1 to -4 depending on the gradient level.

[0081] In Example 2, we assume that the user 1 is in his early 60s and has an exercise habit, just like in Example 1. If a change occurs in the rest time while walking according to the walking route guidance created in Example 1, the walking route guidance is recreated using the walking route guidance system 1 of the above embodiment. Specifically, in an example where, after leaving rest point R4 shown in FIG. 8, the user becomes tired from walking uphill at a gradient of 4, and takes a 5-minute break at rest point R5 instead of the planned 2-minute break, the walking route guidance is recreated. The personal walking values ​​are the same as in Table 1 of Example 1.

[0082] When the user 1 departs from the rest point R5, the control unit 22 compares the location information and date and time information planned in the walking route guidance provided by the route guidance creation unit 14 with the actual location information and date and time information, detects a discrepancy of three minutes, and determines that the walking situation has changed. In response to the determination by the control unit 22, the route guidance creation unit 14 creates walking route guidance that shortens the rest time by three minutes between the rest point R5 and the goal point G. An example of the created walking route guidance is shown in FIG. 10. Note that FIG. 10 is merely an example, as various walking route guidance can be created even under the same walking conditions.

[0083] As shown in Figures 8 and 10, the original walking route guidance shown in Figure 8 had a rest time of 5 minutes at rest point R6, but as shown in Figure 10, a new walking route guidance has been created that shortens the rest time to 2 minutes.

[0084] [Example 3] Example 3 will be described with reference to Figures 8 and 11. Figure 11 is a diagram showing walking route guidance created in Example 3. In Figure 11, normal roads for the user are shown with thin lines, hard roads are shown with thick lines, flat roads are shown as ±0, uphill roads are shown as +1 to +4, and downhill roads are shown as -1 to -4 depending on the gradient level.

[0085] In Example 3, we assume that the user 1 is in his early 60s and has an exercise habit, just like in Example 1. If a change occurs in the rest interval while walking according to the walking route guidance created in Example 1, the walking route guidance is recreated using the walking route guidance system 1 of the above embodiment. Specifically, we recreate the walking route guidance for an example in which, after leaving rest point R4 shown in Figure 8, the user becomes tired from walking uphill at a gradient of 4 and takes a break before arriving at rest point R5. The personal walking values ​​are the same as in Table 1 of Example 1.

[0086] When user 1 takes a two-minute break while walking from rest point R4 to rest point R5, control unit 22 compares the location information and date and time information planned in the walking route guidance displayed by route guidance generation unit 14 between rest point R4 and rest point R5 with the actual location information and date and time information, and determines that the walking situation has changed at the timing when a two-minute discrepancy occurs. In response to the determination by control unit 22, route guidance generation unit 14 changes the point where user 1 took a break to rest point R5 and generates walking route guidance for a walking route from the point where user 1 took a break to goal point G so that user 1 can take breaks at rest intervals based on user 1's personal walking value. An example of the generated walking route guidance is shown in FIG. 11. Note that various walking route guidance can be generated even under the same walking conditions, and FIG. 11 is merely an example.

[0087] As shown in FIG. 11, from the newly set rest point R5, the user walks uphill at a gradient of 2 and downhill at a gradient of 2, but a new rest point R6 is set at a point where the user 1 has walked for a short rest interval of 6 minutes (see Table 1) on the uphill at a gradient of 2 (see Table 1). Similarly, rest point R7 is also newly set based on the personal walking value of user 1. Comparing FIG. 8 with FIG. 11, it can be seen that the walking route guidance has been recreated with the rest point R newly set.

[0088] [Example 4] Example 4 will be described with reference to Fig. 8 and Fig. 12. Fig. 12 is a diagram showing walking route guidance created in Example 4. In Fig. 12, normal roads for the user are shown with thin lines, hard roads are shown with thick lines, flat roads are shown as ±0, uphill roads are shown as +1 to +4, and downhill roads are shown as -1 to -4 according to the gradient level.

[0089] In Example 4, we assume that the user 1 is in his early 60s and has an exercise habit, just like in Example 1, and after walking on flat ground, the acceleration data and position information on the flat ground are stored in the initial walking data storage unit 16. In this situation, walking route guidance is created using the walking route guidance system 1 of the above embodiment.

[0090] Using the walking route guidance system 1 of the above embodiment, the initial flat ground gait value calculated by the initial flat ground gait value calculation unit 17 from the flat ground acceleration data and position information of the user 1 stored in the initial gait data storage unit 16 is a walking speed of 80 m / min, a rest interval of once every 6 minutes, and a rest time of 2 minutes. The initial terrain-specific gait value estimation unit 18 estimates the initial gait values ​​for each terrain based on the estimation databases 51, 52, and 53 (see FIGS. 5 to 7) prepared in advance in the storage unit 21. Specifically, based on the flat ground walking speed of 80 m / min, the walking speed in column A of the terrain-specific walking speed estimation database 51 is estimated as the initial terrain-specific walking speed of the user 1. Furthermore, based on the flat ground rest interval of 6 minutes, the rest interval in example e of the terrain-specific rest interval estimation database 52 is estimated as the initial terrain-specific rest interval of the user 1. Then, based on a walking speed on flat ground of 80 m / min, a rest interval on flat ground of 6 minutes, and a rest time on flat ground of 2 minutes, the rest time in column Ae-ii of the terrain-specific rest time estimation database 53 is estimated as the initial rest time by terrain for user 1. The estimated initial walking values ​​by terrain are as shown in Table 3.

[0091] [Table 3]

[0092] Based on the estimated initial walking values ​​for each terrain in Table 3, the starting point S and the goal point G are set to the same location, and walking route guidance is created in normal mode with a walking time of 40 minutes.

[0093] Table 3 shows that User 1's initial walking speed by terrain is 80 meters per minute on flat roads, and that the walking speed on uphill slopes with a gradient of 1, downhill slopes with a gradient of 1, and downhill slopes with a gradient of 2 is the same as or faster than the walking speed on flat roads. Therefore, flat roads, uphill slopes with a gradient of 1, downhill slopes with a gradient of 1, and downhill slopes with a gradient of 2 are considered normal roads. Other roads, such as uphill slopes with a gradient of 2, uphill slopes with a gradient of 3, downhill slopes with a gradient of 3, uphill slopes with a gradient of 4, and downhill slopes with a gradient of 4 are considered hard roads. To create route guidance for a 40-minute walk in normal mode, the route guidance creation unit 14 creates walking route guidance so that the walking time on normal roads is 20 to 28 minutes and the walking time on hard roads is 12 to 20 minutes. An example of the created walking route guidance is shown in Figure 12. Note that various walking route guidance can be created even under the same walking conditions, so Figure 12 is merely an example.

[0094] 12, it can be seen that the walking time on the normal road for user 1 is 26 minutes, and the walking time on the hard road for user 1 is 14 minutes, and route guidance for a 40-minute walk in normal mode has been created. It can also be seen that walking route guidance has been created in which rest point R indicating the rest time according to Table 3 is displayed at the point where rest should be taken according to Table 3.

[0095] 8 and 12 and Tables 1 and 3, it can be seen that even when the same user 1 walks for 40 minutes in the same normal mode, the walking route guidance differs depending on the terrain-specific initial walking value estimated from the initial flat ground walking value obtained by walking on flat ground, and the personal walking value obtained by actually walking a route including various terrains. This shows that the walking route guidance differs depending on the personal walking value calculated as the user's walking ability changes, and that by creating walking route guidance using the most recent personal walking value, walking route guidance tailored to the user's walking ability when walking is created.

[0096] As described above, the walking route guidance system 1 of the present invention calculates a personal walking value that indicates the user's walking ability based on the user's acceleration data and position information acquired while walking, and creates walking route guidance based on the calculated personal walking value. This allows a walking route to be created that corresponds to the user's individual walking ability, allowing each user to perform walking exercise that is appropriate for them. Furthermore, even under the same walking conditions, a different walking route can be created simply by changing one turn, allowing the creation of numerous walking routes, so that users can perform walking exercise on different walking routes every day.

[0097] Furthermore, in the walking route guidance system 1 of the present invention, the measurement device 30 acquires the user's acceleration data and position information while the user is walking, and each time the user walks, the personal walking value is calculated from the acquired acceleration data and position information to create walking route guidance. As a result, as the user's walking ability improves through continued walking, a walking route corresponding to the improved walking ability is created, allowing each user to always perform walking exercises appropriate to themselves.

[0098] Furthermore, with the walking route guidance system 1 of the present invention, before creating walking route guidance, walking conditions such as walking time or walking load can be input according to the user's physical condition on that day. This allows the user to walk with a lower load when feeling a little unwell, and walk with a higher load when feeling well. Furthermore, since the start point S and goal point G can be set, the user can easily use the walking route guidance system 1 to create a walking route that suits the user, not only when walking from home as usual, but also when they have some free time while traveling and want to walk.

[0099] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0100] For example, in the above embodiment, the number of steps is calculated, and the rest interval and rest time are calculated based on the calculated number of steps, but this configuration is not necessarily required. For example, based on the position information acquired while walking, it may be determined whether the position information has changed, i.e., whether the person is in the same position, and the rest interval and rest time may be calculated by setting the time spent in the same position as the rest time and the time from the time spent in the same position to the next time as the rest interval.

[0101] Furthermore, in the above embodiment, the walking route guidance system 1 includes the walking condition acquisition unit 13, but this configuration is not necessarily required. For example, if walking route guidance is always performed with the user's home as the start point and goal point, with the same walking time and walking load, walking route guidance can be created if the start point, goal point, walking time, and walking load are set as initial values, so the walking condition acquisition unit 13 does not necessarily have to be provided.

[0102] In addition, in the above embodiment, in order to acquire acceleration data and position information on flat ground, flat ground around the current location is displayed and the user is asked to walk on the flat ground, but this configuration is not necessarily required. For example, the user may be asked to register their age and whether they have a daily exercise habit, and flat ground walking route guidance may be created based on the user's age and exercise habit, and the flat ground walking route guidance may be displayed on the display device 31. In this case, the user walks according to the flat ground walking route guidance.

[0103] Furthermore, in the above embodiment, the walking route guidance system 1 includes the initial gait data storage unit 16, the initial flat terrain gait value calculation unit 17, and the initial terrain-specific gait value estimation unit 18, but this configuration is not necessarily required. For example, when a user uses the walking route guidance system 1 for the first time, the system can be configured to input the user's age and daily exercise habits, and then provide walking route guidance including terrain other than flat terrain from the first time by referencing the acceleration data and location information of other users who are similar in age and exercise habits to the user. In this case, there is no need to walk on flat terrain for a certain period of time or to estimate the initial terrain-specific gait value from the initial flat terrain gait value. Therefore, the walking route guidance system 1 does not need to include the initial gait data storage unit 16, the initial flat terrain gait value calculation unit 17, and the initial terrain-specific gait value estimation unit 18. With this configuration, the walking route guidance method also does not require checking the initial gait data storage unit 16.

[0104] In the above embodiment, the walking route guidance system 1 includes the evaluation unit 19, but this configuration is not necessarily required. For example, if it is sufficient to provide walking route guidance, the evaluation unit 19 may not be particularly provided.

[0105] In the above embodiment, the walking route guidance method is configured so that the user inputs the start point and the finish point, but this is not necessarily the case. For example, the control unit 22 may automatically acquire the user's location information using a GPS provided in the measuring device 30 of the walking route guidance system 1, and create walking route guidance using the acquired location information as the start point and the finish point. [Industrial Applicability]

[0106] The walking route guidance system, walking route guidance method, and walking route guidance program of the present invention provide guidance on walking routes that correspond to an individual's walking ability, and are used by users who walk based on the created walking route guidance, and therefore have industrial applicability.
