Description

  The present invention is used by wearing on a user's body such as an arm or waist, or by storing in a bag or the like carried by the user, and detecting a walking signal corresponding to the user's walking. The present invention relates to a walking simulation apparatus that performs a walking simulation of a course.

2. Description of the Related Art Conventionally, a walking simulation device that detects a walking signal corresponding to a user's walking and performs a walking simulation of a predetermined course has been developed.
For example, Patent Document 1 relates to an apparatus having information on a course to be walked and a midpoint of the course, and virtually traveling the course based on walking distance information obtained from a walking signal by a user. It is disclosed. In addition, as the display to the user, information display from the departure point to the last point, and information display from the middle point to the next point are shown.

  In the invention described in Patent Document 1, the course data shows only the distance information, but if the course is actual, there should be a height difference due to topography, but this is not taken into consideration. Therefore, the walking distance obtained by the walking detection is reflected on the walking distance of the course as it is. In this method, for example, when a user in a living area who walks only on a flat road, the course walking distance is determined only by the distance walked on the flat road.

  That is, in order to obtain the walking distance for walking on the course, the invention described in Patent Document 1 only calculates the walking distance from the number of steps and the step length, so the actual walking state is a flat road. However, the walking distance is determined regardless of whether it is uphill, downhill, or up and down stairs. Therefore, even if the user intentionally increases the exercise load, there is a problem that the effort of the user is not reflected because there is no difference in the distance traveled on the course.

FIG. 2 is a characteristic diagram showing the relationship between the altitude change coefficient 1 (first altitude change coefficient) and the altitude difference in the walking course (end altitude−starting altitude). The altitude change coefficient 1 is selected so as to increase as a steep uphill and decrease as a steep uphill.
FIG. 3 is a flowchart showing the processing of the walking simulation apparatus according to the present embodiment, and is processing performed mainly by the processing unit 103 executing a program stored in the storage unit 105.

Hereinafter, the operation of the walking simulation apparatus according to the present embodiment will be described with reference to FIGS.
The altitude sensor 106 outputs an altitude signal corresponding to the altitude. The processing unit 103 stores the altitude (starting altitude) information corresponding to the altitude signal in the storage unit 105 (step S301).
Next, the processing unit 103 controls the time measuring unit 107 to start a time measuring operation (time counting timer start) (step S302).

On the other hand, the body motion sensor 101 detects the user's walking and outputs a corresponding walking signal. The walking signal detection unit 102 detects a walking signal from the body motion sensor 101, converts it into a digital signal, and outputs it. When the processing unit 103 detects the walking signal from the body motion sensor 101 (step S303) and determines that there is a walking signal (step S304), the processing unit 103 adds the current walking distance (to the stride) to the walking distance stored in the storage unit 105. (Corresponding) is added (step S305).
Next, when the processing unit 103 determines that the timing operation has been performed for a predetermined time (timer timer end) (step S306), the processing unit 103 obtains the altitude at that time from the altitude sensor 106 and stores the altitude information as the end altitude information. (Step S307).

Next, the processing unit 103 refers to the characteristics of the altitude change coefficient 1 of FIG. 2 stored in the storage unit 105, and calculates the altitude change coefficient 1 based on the start altitude and the end altitude (step S308).
Next, the processing unit 103 multiplies the walking distance (actual walking distance) stored in the storage unit 105 by the altitude change coefficient 1 to thereby increase the walking distance on the virtual walking course corresponding to the walking distance ( (Course walking distance) is calculated and added to the cumulative course walking distance stored in the storage unit 105 (step S309). As a result, the processing unit 103 calculates the cumulative course walking distance up to now.

The processing unit 103 controls the display unit 104 to display the cumulative course walking distance on the display unit 104 (step S310), resets the walking distance stored in the storage unit 105, and then proceeds to processing step S301. Return (step S311).
If the processing unit 103 determines in the processing step S306 that the clock timer has not expired, the processing unit 103 returns to the processing step S303. In addition, when the processing unit 103 determines that there is no walking signal in the processing step S304, the processing unit 103 proceeds to the processing step S306 without performing the processing step S305.

In this way, since the walking distance is calculated and displayed by multiplying the walking distance by a coefficient corresponding to the amount of change in the altitude of the virtual walking course, the user actually goes uphill or on stairs. When walking, the exercise load increases and the course walking distance is longer than when walking on a flat road. In addition, when a walking exercise is performed downhill or down stairs, the actual exercise load is reduced, so that the course walking distance is shorter than when walking on a flat road.
Therefore, it is possible to provide a walking simulation apparatus that allows the user to make an effort to increase the actual exercise load in order to intentionally advance the course walking distance. Therefore, there is an effect that the user can experience the walking exercise load due to the difference in height of the course.

Next, altitude difference is set between a plurality of points on the walking course, and the walking simulation considering not only the altitude detected by the altitude sensor 106 but also the altitude change between the plurality of points on the virtual walking course. Will be described.
FIG. 4 is a table showing course information. As shown in FIG. 4, the course information includes a plurality of point numbers located between the start point and the end point, the distance between the points, and the altitude change coefficient 2 (second altitude change coefficient) associated with each point. It has become. The walking course is composed of a plurality of course elements (between points).
FIG. 5 is a diagram showing the altitude change of the walking course corresponding to the course information of FIG. The distance of FIG. 5 means the distance of the slope between each point.

FIG. 6 is a table showing the course walking distance and the initial value of the next point number. As an initial value, 0 is stored as the course walking distance, and 1 is stored as the next point number.
FIG. 7 is a flowchart showing the process of the walking simulation apparatus according to the present embodiment, which is a process mainly performed by the processing unit 103 executing a program stored in the storage unit 105.

Hereinafter, the operation in consideration of not only the altitude detected by the altitude sensor 106 but also the altitude change between a plurality of points on a virtual walking course will be described with reference to FIGS.
First, the processing unit 103 controls the altitude sensor 106 to cause the altitude sensor 106 to output an altitude signal corresponding to the altitude. The processing unit 103 stores the altitude (starting altitude) information corresponding to the altitude signal in the storage unit 105 (step S301).
Next, the processing unit 103 controls the time measuring unit 107 to start a time measuring operation (time counting timer start) (step S302).

On the other hand, the body motion sensor 101 detects the user's walking and outputs a corresponding walking signal. The walking signal detection unit 102 detects a walking signal from the body motion sensor 101, converts it into a digital signal, and outputs it. When the processing unit 103 detects the walking signal from the body motion sensor 101 (step S303) and determines that there is a walking signal (step S304), the processing unit 103 adds the current walking distance (to the stride) to the walking distance stored in the storage unit 105. (Corresponding) is added (step S305).
Next, when the processing unit 103 determines that the timing operation has been performed for a predetermined time (timer timer end) (step S306), the processing unit 103 obtains the altitude at that time from the altitude sensor 106 and stores the altitude information as the end altitude information. (Step S307).

Next, the processing unit 103 refers to the characteristics of the altitude change coefficient 1 in FIG. 2 stored in the storage unit 105, and calculates the altitude change coefficient 1 based on the start altitude and the end altitude (step S308).
Next, the processing unit 103 reads the altitude change coefficient 2 of the corresponding spot number from the storage unit 105 (step S701). In the initial state, the point number is 1, and referring to the course information in FIG. 4, the altitude change coefficient 2 in this case is 0.8. That is, the altitude change coefficient 2 of the course element from the spot number 0 to the spot number 1 is 0.8.

Next, the processing unit 103 corrects the walking distance by the altitude change coefficient 1 and the altitude change coefficient 2 (for example, by multiplying the walking distance by the altitude change coefficient 1 and the altitude change coefficient 2), thereby the walking distance. The walking distance (course walking distance) on the course corresponding to is calculated and added to the cumulative course walking distance stored in the storage unit 105 (step S702). As a result, the processing unit 103 calculates the cumulative course walking distance up to now.
The processing unit 103 controls the display unit 104 to display the cumulative course walking distance on the display unit 104 (step S310), and resets the walking distance stored in the storage unit 105 (step S311).

Next, the processing unit 103 determines whether or not the current cumulative walking distance exceeds the point distance (step S703), and when it is determined that the current cumulative walking distance exceeds the point distance, the point number is added. The process returns to step S301 (step S704).
On the other hand, when the processing unit 103 determines in the processing step S703 that the current cumulative walking distance does not exceed the point distance, the processing unit 103 immediately returns to the processing step S301.
This makes it possible to perform a walking simulation in consideration of climbing, descending, actual climbing, and descending on a virtual walking course.

As described above, according to the walking simulation device according to the present embodiment, coefficient information corresponding to the amount of change in altitude of the walking course is provided in the course information of the virtual walking course, the number of steps is measured, and the user's While calculating the walking distance according to the stride value, the result of multiplying the walking distance by the altitude change coefficient according to the altitude change amount of the walking course is added to the previous walking distance to obtain the walking distance on the walking course. ing.
Therefore, even if you actually walk on a flat road by the altitude change coefficient based on the height difference information set in the course information, if the walking course is uphill, the course walking distance is shortened, and the walking course is downhill. Then, the course walking distance becomes longer. Therefore, there is an effect that the user can experience the walking exercise load due to the difference in height of the walking course.

  The present invention is applicable to a walking simulation device that detects a walking signal corresponding to a user's walking and performs a walking simulation of a predetermined course.
