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. For this reason, the walking distance obtained for walking detection is reflected in 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.

  This invention is made in view of the said problem, and makes it a subject to enable a user to experience the walking exercise | movement load by the height difference of a course.

According to the present invention, detection means for detecting a walking and outputting a corresponding walking signal, a plurality of course elements constituting a walking course, and an altitude change coefficient given according to an altitude change amount of each course element. A storage means for storing in association; a calculation means for calculating a current cumulative walking distance in the walking course by correcting a walking distance calculated based on a walking signal from the detection means by the altitude change coefficient; There is provided a walking simulation device comprising display means for displaying the cumulative walking distance.
The calculating means calculates the current cumulative walking distance in the walking course by correcting the walking distance calculated based on the walking signal from the detecting means with the coefficient stored in the storage means. The display means displays the cumulative walking distance.

  Here, the step of the user is stored in the storage unit, and the calculation unit calculates the corrected walking distance of the current walking by multiplying the step and the altitude change coefficient, and accumulates the current steps. The current cumulative walking distance in the walking course may be calculated by adding to the walking distance.

FIG. 1 is a block diagram of a walking simulation apparatus according to an embodiment of the present invention.
The walking simulation device is used by being worn on a body such as a user's arm or waist, or stored in a bag or the like carried by the user.
In FIG. 1, a walking simulation device detects a user's walking (including running) and outputs a corresponding walking signal, and a walking signal that detects a walking signal, converts it into a digital signal, and outputs it. Based on the walking signal from the detection unit 102 and the walking signal detection unit 102, a processing unit 103 that performs calculation processing of data related to walking distance, such as counting the number of steps and calculating the walking distance, a display unit 104, and a storage unit 105 It has.

The body motion sensor 101 is constituted by an acceleration sensor. The storage unit 105 stores the user's stride information (user stride information), the course information of the course to be walked, the course walking distance (current cumulative walking distance) calculated by the processing unit 103 from the product of the number of steps and the stride, Point number information is stored. The user stride information can be input and registered by the user from an operation unit (not shown).
Here, the body motion sensor 101 and the walking signal detection unit 102 constitute detection means. The processing unit 103 constitutes a calculation unit, the display unit 104 constitutes a display unit, and the storage unit 105 constitutes a storage unit.

FIG. 2 is a table showing the course information. As shown in FIG. 2, the course information is information in which a plurality of point numbers located between the start point and the end point, the distance between the points, and the altitude change coefficient at each point are associated with each other. The walking course is composed of a plurality of course elements (between points).
FIG. 3 is a diagram showing a change in altitude of the walking course corresponding to the course information of FIG. The distance of FIG. 3 means the distance of the slope between each point.

FIG. 4 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. 5 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 of the walking simulation apparatus according to the present embodiment will be described with reference to FIGS.
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 a walking signal from the body motion sensor 101 (step S501) and determines that there is a walking signal (step S502), the processing unit 103 reads the altitude change coefficient of the corresponding point number (step S503).
In the initial state, the point number is 1, and referring to the course information in FIG. 2, the altitude change coefficient in this case is 0.8. That is, the altitude change coefficient of the course element from point number 0 to point number 1 is 0.8.

  The processing unit 103 multiplies the user's stride stored in the storage unit 105 by the altitude change coefficient, and adds the result to the cumulative walking distance (course walking distance) so far to calculate the current cumulative walking distance ( Step S504). In other words, the processing unit 103 calculates the corrected walking distance in consideration of the altitude change by the formula [current course walking distance = previous course walking distance + (step length × altitude change coefficient)].

Next, the processing unit 103 controls the display unit 104 to display the current course walking distance on the display unit 104 (step S505).
Next, the processing unit 103 determines whether or not the current cumulative walking distance exceeds the point distance (step S506), and when the current cumulative walking distance exceeds the point distance and breaks, the point number is added and processed. The process returns to step S501 (step S507).
On the other hand, when the processing unit 103 determines that the current cumulative walking distance does not exceed the point distance (step S506), the processing unit 103 returns to the processing step S501.

As described above, according to the walking simulation apparatus according to the present embodiment, coefficient information corresponding to the course height change amount is provided in the course information, the number of steps is measured, and the walking distance according to the step value of the user And the result of multiplying the walking distance by the altitude change coefficient corresponding to the amount of altitude change of the course is added to the immediately preceding walking distance to obtain the walking distance on the course.
Therefore, even if you walk on a flat road by the altitude change coefficient based on the height difference information set in the course information, the course walking distance is shortened if the course is uphill, and if the course is downhill, the course The 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 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.
