An embodiment of the present invention will be described below with reference to the drawings. In this embodiment,
An exercise system including both a balance board and a mobile terminal device will be described as an example.

[Outline of exercise system Sys]
FIG. 1 is a schematic diagram showing an example of a balance exercise using the exercise system Sys in the present embodiment.
FIG. 1 shows a user U (an example of a user) performing a balance exercise using the exercise system Sys.
Hereinafter, this is an example of a case in which it is simply referred to as “balance exercise”. Exercise system Sys
Includes a balance board BB and a mobile terminal device 50 (an example of a terminal device).
In this figure, the user U rides on the balance board BB on which the mobile terminal device 50 is placed and is in balance. In this figure, the X-axis direction, the Y-axis direction, and the Z-axis direction orthogonal to each other are the width direction, the depth direction, and the height direction of the balance board BB, respectively.

The balance board BB includes a board section B. The upper surface Ba of the board portion B has an elliptical shape. Here, the major axis direction of the elliptical ellipse is the width direction, and the minor axis direction is the depth direction. That is, the upper surface Ba is formed so that the length L1 in the width direction is longer than the length L2 in the depth direction.
The height direction is the normal line direction of the upper surface Ba and corresponds to the thickness direction of the board portion B. In the use state of the balance board BB shown in FIG. 1, the width direction is a direction in which both feet or shoulders of the user U are lined up, and corresponds to the lateral direction, lateral direction, or left-right direction of the user U's body. In this usage state, the depth direction corresponds to the front-back direction of the body of the user U, and the height direction corresponds to the vertical direction of the body of the user U.

The balance board BB further includes an attachment C. The attachment C is detachably attached to the center of the board portion B when viewed from the thickness direction (Z-axis direction) of the board portion B so as to project from the lower side of the board portion B. The balance board BB is used by installing the balance board BB on the floor surface S so that the attachment C faces the floor surface S side. User U
In the widthwise direction, balance exercise is performed by placing one's feet on both sides of the central region to balance. That is, the user U makes a balance so as to suppress swinging about the contact point between the floor surface S and the attachment C as a fulcrum. In order to train the body, the user U performs a balance exercise so that the edge of the board portion B does not contact the floor surface S. Thereby, the user U can train a sense of balance, a trunk, and the like.

The mobile terminal device 50 is, for example, a smartphone. The smartphone is a plate-shaped terminal device including a display unit 51 and a sensor. The mobile terminal device 50 is placed in the central region of the upper surface Ba of the board portion B when the user U performs a balance exercise. At this time, the display unit 51
It is directed to the upper side of the board part B. Accordingly, the user U can see the display unit 51 only by facing down while performing the balance exercise. Further, the central region where the mobile terminal device 50 is placed is located directly below the head of the user U. This allows the user U to turn his / her face directly below when looking at the display unit 51, and does not need to turn his / her face laterally or move his / her head.
Therefore, the balance board BB can prevent the balance in the width direction from being lost because the user U views the display unit 51.

The mobile terminal device 50 displays the tilt information indicating the tilt amount of its own device by the built-in sensor. Here, by mounting the mobile terminal device 50 on the balance board BB, the tilt information of the mobile terminal device 50 can be displayed on the display unit 51 as the tilt information of the balance board. Accordingly, the exercise system Sys supports the balance exercise using the balance board BB of the user U.

The board portion B is provided with a protruding portion 11 that protrudes from the upper surface Ba thereof. The protruding portion 11 surrounds the mobile terminal device 50 placed in the central region of the upper surface Ba of the board portion B. Accordingly, the protruding portion 11 suppresses the mobile terminal device 50 from sliding off the balance board BB even when the upper surface Ba is inclined with respect to the horizontal during the balance exercise. Also, the protrusion 11
Suppresses the foot of the user U from hitting the side surface of the mobile terminal device 50 when the upper surface Ba is inclined with respect to the horizontal. Since the projecting portion 11 projects from the upper surface Ba, the user U is made aware of not stepping on the projecting portion 11 and the user U is prevented from stepping on the mobile terminal device 50 with his / her foot. Even if the user U steps on the mobile terminal device 50, since the protrusion 11 receives the weight of the user U, the force applied to the mobile terminal device 50 is reduced as compared with the case where the protrusion 11 is not provided. Let In this way, the balance board BB can protect the placed mobile terminal device 50 from damage.

[Balance board BB]
FIG. 2 is a perspective view of the balance board BB in the present embodiment. Balance board BB
Includes a board portion B. Further, the board portion B includes a protruding portion 11 that surrounds the mobile terminal device 50 placed in the central region of the upper surface Ba of the board portion B. That is, the balance board BB realizes a highly original design by the projecting portion 11 provided at the center of the upper surface Ba of the board portion B. That is, the balance board BB protects the mobile terminal device 50 from damage by protruding the projecting portion 11 surrounding the mobile terminal device 50 from the upper surface Ba, and at the same time, the mobile terminal device 5 is protected.
The design can be based on a new concept that the user U can be provided with a balance exercise linked with zero. From this point of view, the overall shape of the board portion B and the shape and number of protrusions 14 provided on the upper surface Ba, which will be described later, do not contribute to the unique design. In this figure, as in FIG. 1, the X-axis direction, the Y-axis direction, and the Z-axis direction orthogonal to each other are the width direction, the depth direction, and the height direction of the balance board, respectively.

The upper surface Ba of the board portion B is formed in an elliptical shape. The upper surface Ba also has a shape that is line-symmetric with respect to the first major axis MA1 that is the major axis of the ellipse or the first minor axis MB1 that is the minor axis of the ellipse. The length L1 (major axis) of the first major axis MA1 is, for example, 4 times or more and 6 times or less than the assumed foot width of the user (average foot width average value). This allows the user U to perform a balance exercise in a state in which both feet are widened by about one foot width. Further, the length L2 (minor axis) of the first short axis MB1 is not less than 1 time and not more than 2 times the expected user's foot length (average value of general foot lengths). That is, in the balance board BB, the area on which the foot is placed is wide in the width direction and narrow in the depth direction.
The upper surface Ba of the present invention is not limited to an elliptical shape, but may be an elliptical shape, a rectangular shape, or a rhombus shape. That is, the shape of the upper surface Ba has a length L in the width direction (an example of the first direction).
1 (an example of 1st length) is a shape longer than length L2 (an example of 2nd length) in a depth direction (an example of a 2nd direction). Further, the shape of the upper surface Ba is such that the first major axis MA1 that is an axis parallel to the width direction and that passes through the center or the center of gravity of the shape of the upper surface Ba or the first minor axis MB1 that is an axis parallel to the depth direction. Thus, it is also a line-symmetrical or substantially line-symmetrical shape. Here, the substantially line-symmetrical shape means that the upper surface Ba also includes a shape that is slightly asymmetrical with respect to the first long axis MA1 or the first short axis MB1.

The balance board BB includes a mounting portion 12. The mounting portion 12 is provided in the central region of the upper surface Ba of the board portion B. The mounting portion 12 is a mounting surface 12a on which the mobile terminal device 50 is mounted.
Have. The plate-shaped portable terminal device 50 has a rear surface (a surface opposite to the display unit 51) on the mounting surface 12.
It is placed in contact with a. In other words, the placement surface 12a is a surface that contacts the back surface of the mobile terminal device 50.

The mounting surface 12a is parallel or substantially parallel to the upper surface Ba of the board portion B. The term “substantially parallel” includes that the mounting surface 12a is slightly inclined with respect to the upper surface Ba of the board portion B. The mounting surface 12a has a rectangular shape corresponding to the planar view shape of the mobile terminal device 50. Mounting surface 12
a is also a shape that is line-symmetric with respect to the second long axis MA2 and the second short axis MB2.
The length of the long side and the short side of the mounting surface 12a in a plan view is, for example, the portable terminal device 50 in a plan view.
It is several mm to several cm longer than the short side and the long side. However, since the user U uses his / her own mobile terminal device 50 on the balance board BB, it is assumed that mobile terminal devices 50 of various sizes are placed. Therefore, the length of the long side and the short side of the placement surface 12a is several mm to several cm longer than the length of the longest long side and the short side of the assumed portable terminal device 50. For example,
The long side (the length of the second long axis MA2 is the same) of the mounting surface 12a is 160 mm to 180 mm, and the short side (the length of the second short axis MB2 is the same) is 80 mm to 100 mm.

The long side of the mounting surface 12a and the second long axis MA2 are parallel to the depth direction of the balance board BB and the first short axis MB1. On the other hand, the short side of the mounting surface 12a and the second short axis MB2 are parallel to the width direction of the balance board BB and the first long axis MA1.
As a result, when the mobile terminal device 50 is placed, its long sides are parallel to the depth direction of the balance board BB and its short sides are parallel to the width direction. Therefore, when the user U rides on the balance board BB as in the use state shown in FIG. 1, the vertical direction and the horizontal direction of the visual match with the vertical direction and the horizontal direction of the display unit 51 of the mobile terminal device 50. . That is, the user U can easily see the display of the mobile terminal device 50. In this case, the mobile terminal device 50 preferably has a vertical display, that is, a display in which the vertical direction of the display unit 51 is the vertical direction.
The mounting surface 12a has a long side and a second long axis MA2 parallel to the width direction of the balance board BB and the first long axis MA1, and a short side and a second short axis MB2 of the balance board BB are deep. It may be parallel to the direction and the first short axis MB1. In this case, the mobile terminal device 50
Horizontal display, that is, display in which the horizontal direction of the display unit 51 is the vertical direction is suitable.
In this way, the balance board BB has the shape of the upper surface Ba thereof having anisotropy, and in the usage state of the user U due to this, the portable terminal device 50 is placed in a direction that is easily seen by the user U during the balance exercise. Therefore, the shape and direction of the mounting surface 12a are determined. Further, the display of the display unit 51 (application screen described later) can also be fixed by fixing the vertical direction.

A recess 12B is formed in the mounting portion 12 at the center of the mounting surface 12a and is recessed from the mounting surface 12a. The recess 12B is a housing portion that houses an external sensor. Providing the housing section also supports a mobile terminal device that does not include a sensor. Note that the recess 12B may be omitted if the use is limited to the mobile terminal device 50 having a built-in sensor.

As described above, the projecting portion 11 projects around the mounting portion 12 with respect to the upper surface Ba of the board portion B. The periphery of the mounting portion 12 extends along the peripheral edge of the mounting surface 12a, and the mounting surface 1
It is a region surrounding 2a.
The protrusion 11 includes two long side protrusions 11A and 11B and two short side protrusions 11C and 11D.
Are integrally formed. The long side protrusions 11A and 11B respectively extend in the direction along the long sides of the mounting surface 12a. The short side protruding portions 11C and 11D are respectively placed on the mounting surface 12
It extends in the direction along each short side of a.
The long-side protruding portions 11A, 11B and the short-side protruding portions 11C, 11D are wall surfaces 11w facing the four side surfaces 50w of the mobile terminal device 50 in a state where the mobile terminal device 50 is mounted on the mounting portion 12, respectively. It is configured to include. That is, the projecting portion 11 is configured to include four wall surfaces 11w that face each of the four side surfaces 50w of the mobile terminal device 50 when the mobile terminal device 50 is mounted on the mounting portion 12. In addition, part or all of the long side protrusions 11A and 11B and the short side protrusions 11C and 11D may not be integrally formed.

The short side protruding portion 11D is composed of two side dividing protruding portions 11D1 and 11D2. The two side dividing protrusions 11D1 and 11D2 are formed in the direction of the short side of the mounting surface 12a with a space such that fingers can be inserted.
The space between the side division protrusions 11D1 and 11D2 is located at the middle of the short side protrusion 11D in the longitudinal direction. This distance is larger than the width of the fingers, for example, 20 mm or more and 25 to 35 mm.
Is preferred. In addition, it is preferable that the widths of the wall surfaces 11w of the side dividing protrusions 11D1 and 11D2 facing the side surface 50w of the mobile terminal device 50 are at least 10 mm or more.

In the height direction (Z-axis direction) of the balance board BB, the height of the protruding portion 11 with respect to the upper surface Ba from the upper surface Ba to the upper end 11e (an example of the upper portion of the protruding portion) is two long-side protruding portions 1
It is the same in each of 1A, 11B and the two short side protrusions 11C, 11D. The upper end 11e of the protrusion 11 is preferably formed as a flat surface (upper surface) as shown in the figure. In addition, the upper end 11e of the protrusion 11 does not need to be a flat surface, for example, a curved curved surface or an uneven surface, as long as the protrusion 11 can suppress the mobile terminal device 50 from sliding off the balance board BB. May be formed on the upper surface, and the upper surface may be subjected to surface processing for designing.

A non-projecting portion 13 that does not project from the upper surface Ba of the board portion B is provided between the two side division protruding portions 11D1 and 11D2. The non-projecting portion 13 extends along the peripheral edge of the mounting surface 12a from the one side dividing protrusion 11D1 to the other side dividing protrusion 11D2. Non-projecting part 13
The upper end of is located at the same height as the upper surface Ba, but may be located lower than the upper surface Ba, for example. As a result, the protrusion 11 surrounds the mounting surface 12a except between the two side division protrusions 11D1 and 11D2. In other words, the projecting portion 11 does not entirely surround the mounting surface 12a.

Of the upper surface Ba of the board portion B, which is located inside the edge region on the outer peripheral side in the region excluding the central region where the mounting portion 12 is provided and the region around the mounting portion 12 where the protruding portion 11 is provided. In the footrest area on which both feet are placed, a plurality of non-slip protrusions 14 protruding from the upper surface Ba are formed. Each of the protrusions 14 is formed in an arc shape centered on the center of the upper surface Ba with a space in the radial direction. The plurality of protrusions 14 are used as marks of positions where both feet are placed on the upper surface Ba, and also prevent the both feet from sliding on the upper surface Ba during the balance exercise. Further, the protrusion 14 increases the strength of the upper surface Ba of the board B as compared with the case where the protrusion 14 is not formed. In addition, each protrusion 1
The shape and arrangement of 4 are arbitrary.

The slip prevention sheet 122 is, for example, a rubber sheet having a friction coefficient larger than that of the upper surface 121a of the base portion 121. The slip prevention sheet 122 constitutes the mounting surface 12 a of the mounting portion 12. As a result, the mounting surface 12a suppresses slippage of the mobile terminal device 50 mounted on the mounting surface 12a.
In addition, unevenness may be formed on the upper surface (mounting surface 12a) of the slip prevention sheet 122. The unevenness can increase the frictional force with the mobile terminal device 50.

The mounting surface 12a is positioned lower than the upper end 11e of the protrusion 11 and lower than the upper surface Ba of the board portion B. The balance board BB can be mounted on the mounting portion 12 without protruding from the protruding portion 11, even in the portable terminal device 50 having a thickness larger than the height of the protruding portion 11 with respect to the upper surface Ba.
The mounting surface 12 a is located lower than the non-projecting portion 13. That is, the slip prevention sheet 1
22 or its side surface is located lower than the non-projecting portion 13. As a result, the user U puts his / her fingers into the non-protruding portion 13 which is the gap between the protruding portions 11, and places the portable terminal device 5 on the placing portion 12.
When 0 is taken out, it is possible to prevent the fingers from being caught on the slip suppression sheet 122, and to reduce damage to the slip suppression sheet 122.
In FIG. 5, the non-projecting portion 13 is located at the same height as the upper surface Ba of the board portion B, but may be located lower than the upper surface Ba of the board portion B, for example.

The height of the non-projecting portion 13 with respect to the mounting surface 12a is smaller than the thickness (for example, 6 to 10 mm) of the mobile terminal device 50 mounted on the mounting surface 12a, and for example, of the mobile terminal device 50. It may be 2/3 or less of the thickness. Thereby, between the two side division protrusions 11D1 and 11D2 (
A part of the side surface of the mobile terminal device 50 placed on the placement surface 12a can be exposed through an example of a gap between the protrusions 11 formed by the non-projecting portions 13.
The height of the protrusion 11 with respect to the mounting surface 12a is equal to or more than the assumed thickness of the mobile terminal device 50. That is, the upper portion (display surface) of the mobile terminal device 50 placed on the placing surface 12a.
Does not project from the upper end 11e of the projecting portion 11 in the height direction. However, the present invention is not limited to this, and the height of the protruding portion 11 may be smaller than the thickness of the mobile terminal device 50.

The upper end 13a of the non-projecting portion 13 is located farther from the edge of the mounting surface 12a than the protruding portion 11, that is, is spaced apart from the mounting surface 12a. A side surface 13h of the non-projecting portion 13 that faces the mounting surface 12a side extends obliquely from the edge of the mounting surface 12a to the upper end 13a of the non-projecting portion 13. The side surface 13h of the non-projecting portion 13 is curved so that the inclination angle of the side surface 13h increases from the mounting surface 12a toward the non-projecting portion 13. The upper end 13a of the non-projecting portion 13 may be formed as a flat surface (upper surface) as shown in the figure,
For example, it may be formed into a curved curved surface or an uneven surface.
Since the upper end 13a of the non-protruding portion 13 is positioned with a gap from the placing portion 12, the side surface of the portable terminal device 50 is placed on the placing portion 12 when the portable terminal device 50 is placed on the placing portion 12. , Spaced apart from the upper end 13a of the non-projecting portion 13. Therefore, when the mobile terminal device 50 is taken out from the mounting portion 12, the fingers of the user U are held by the upper end 13a of the non-projecting portion 13 and the mobile terminal device 5.
It can be inserted between the side surface of the mobile terminal device 50 and the side surface of the mobile terminal device 50 to reach an area near the mounting surface 12a. As a result, the fingers of the user U can be easily hooked on the side surface of the mobile terminal device 50, and the mobile terminal device 50 placed on the placing part 12 can be easily taken out. The slip suppressing sheet 122 may be provided so as to overlap a part or all of the side surface 13h of the non-projecting portion 13.

In the balance board BB of the present embodiment, the two side division protrusions 11D1 and 11D1
Between D2, instead of the non-projecting portion 13, a low region portion (from the upper surface Ba of the board portion B (
An example of a low region) may be provided. The height of the low region portion from the upper surface Ba is lower than that of the protruding portion 11. That is, the low region portion is located lower than the upper end 11e of the protruding portion 11. In this case, the low region part forms a low region lower than the upper end 11e as a part of the protrusion 11.

[Mobile terminal device 50]
Next, the mobile terminal device 50 will be described.
The mobile terminal device 50 includes the installed balance board BB application (
Hereinafter, the balance board BB will be executed by executing the "balance board application".
Display the balance exercise (balance measurement) instruction and exercise result (measurement result) using. The balance board application detects a tilt amount of the mobile terminal device 50 itself using a sensor (acceleration sensor or the like) built in the mobile terminal device 50. The mobile terminal device 50 is the balance board B.
In the state of being mounted on B, the balance board application generates tilt information indicating the tilt amount of the balance board BB based on the tilt amount detected by the sensor. Then, the balance board application displays the tilt information of the balance board BB on the screen displayed on the display unit 51 of the mobile terminal device 50 by the distance and direction from the reference point (origin, center point) on the polar coordinates. That is, the display unit 51 of the mobile terminal device 50 mounted on the balance board BB is
The tilt information of the balance board BB can be displayed. Below, the screen displayed on the display unit 51 by the balance board application is referred to as an “app screen”.

Here, the function of the balance board application will be described. Various settings necessary for the balance exercise using the balance board BB can be performed on the application screen before placing the mobile terminal device 50 on the balance board BB, for example. The balance board application displays an application screen for performing various settings related to training for performing balance exercise, and performs various settings according to the operation of the user U. When all settings are completed, the application screen will transition to the training start screen. When this screen is displayed, the mobile terminal device 50 can be placed at a predetermined position on the balance board BB to start training (balance exercise). Below, FIG.
The flow of various settings in the balance board application will be described with reference to the transition diagram of the application screen shown in.

FIG. 6 is a transition diagram showing an example of an application screen regarding various settings according to the present embodiment. (A) Training screen selection screen, (b) Mode selection screen, (c) Board A level selection screen and (d) a safety area level selection screen are shown. The balance board application changes screens in the order of (a), (b), (c), and (d) according to the operation of the user U.
Hereinafter, each application screen will be described in order.

(A) Training method selection screen This is a screen for selecting a training method for balance exercise. For example, the training method has two modes, "PRACTICE (practice)" and "TIME TRIAL (time trial)". "PRACTICE" is for developing balance and is a mode in which training (balance exercise) can be continued even if the inclination of the balance board BB exceeds a predetermined range. "TIME TRIAL" is for measuring the balance force, and the balance board B is in a state where the inclination of the balance board BB does not exceed a predetermined range.
In this mode, you can measure the time you can ride B. The above-mentioned predetermined range indicates a range of inclinations for determining that the balance board BB is in a balanced state, and is hereinafter referred to as a "safety area". On the training method selection screen shown in the figure, text information prompting the user to select a training method, an operation area for selecting "PRACTICE", and an operation area for selecting "TIME TRIAL" are displayed. The balance board application allows the user U to select a training method by accepting an operation of selecting one of the operation areas. When the training method is selected, the screen transitions to the (b) mode selection screen.

(B) Mode selection screen This is a screen for selecting the exercise mode of balance exercise. For example, in the exercise mode, "CENTER MODE (center mode)" in which the safety area is set at the center, and "RANDOM MODE (random mode)" in which the safety area is displayed at random positions
There are two modes. In other words, "CENTER MODE" is the balance board BB
This is a mode that keeps the ground level with the ground. "RANDOM MODE" is a mode in which the balance board BB is kept tilted in a randomly determined direction. On the mode selection screen shown in the figure, text information prompting the user to select the mode, an operation area for selecting "CENTER MODE", and an operation area for selecting "RANDOM MODE" are displayed. The balance board application allows the user U to select the exercise mode by accepting the operation of selecting one of the operation areas. When the exercise mode is selected, the screen changes to (c) board level selection screen.

(C) Board level selection screen This is a screen for selecting the board level according to the mounting state of the attachment C on the balance board BB. The board level is a level corresponding to the difficulty level of the balance exercise. Depending on how the attachment C is attached to the balance board BB, the ease of tilting the balance board BB changes and the difficulty level of the balance exercise changes. There are three board levels: "LEVEL1: For beginners", "LEVEL2: Intermediate level" and "LEVEL3: Advanced level".
“LEVEL1: For beginners” is a board level to be selected when the balance board BB is used in a state where the attachment C is not attached (a state where the attachment C is removed). This board level is for a person who has just begun training (balance exercise) because the maximum amount of inclination of the balance board BB is small because the downward projection height of the balance board BB is the lowest. "LEVEL2: Intermediate level" is a board level to be selected when the balance board BB is used in a state where the attachment C is mounted by inserting the attachment C into a deep slit (the second groove C11B shown in FIG. 3). This board level is for those who have a higher protruding amount of the balance board BB to the lower side than the state in which the attachment C is not mounted, and have a balance force. “LEVEL3: For advanced users” is a board level to be selected when the balance board BB is used in a state where the attachment C is mounted by inserting the attachment C into a shallow slit (the first groove C11A shown in FIG. 3). This board level is intended for those who are confident in their balance power, because the protruding height of the balance board BB to the lower side is further increased. On the board-level selection screen shown in the figure, text information prompting the board-level selection and "LE
An operation area for selecting "VEL1: For beginners", an operation area for selecting "LEVEL2: For intermediate users", and an operation area for selecting "LEVEL3: For advanced users" are displayed. The balance board application allows the user U to select the board level by accepting an operation of selecting one of the operation areas. When the board level is selected, the screen changes to (d) Level selection screen in the safety area.

(D) Safety area level selection screen This is a screen for selecting the level of the size of the safety area. At the level of the safety area, "LEVEL1: For beginners", "LEVEL2: For intermediate level" and "LEVEL3"
: For advanced users ". "LEVEL1: For beginners" has the largest safety area. If you do not have a good balance, it is recommended to start at this level. "LEVEL2: Intermediate level" has a safety area of "LEVEL2.
It is a level intermediate between "1: For beginners" and "LEVEL3: For advanced users". This level is for those who can balance even when the balance is strong and unstable. "LEVEL3: For advanced users" is for advanced users who have the smallest safety area and the highest degree of difficulty. On the safety area level selection screen shown in the figure, there are text information for prompting the selection of the safety area level, an operation area for selecting "LEVEL1: For beginners", and an operation area for selecting "LEVEL2: Intermediate level". , "LEVE
An operation area for selecting "L3: for advanced users" is displayed. The balance board app is
By accepting the operation of selecting one of the operation areas, the user U is made to select the level of the safety area. Once the safety area level is selected, the training method,
The operation mode and training level (board level and safety area) are confirmed. That is, in each combination of the two training methods and the two operation modes, 9 types of levels can be selected from 3 types of board levels × 3 types of safety area levels. After selecting the level, the screen changes to the app screen (training start screen) where you can start the balance measurement.

FIG. 7 is a diagram showing an example of a training start screen (before START) according to the present embodiment. The training start screen shown in (a) of FIG. 7 is a screen displayed before the start of training (before the training start operation is performed), and the selected exercise mode, board level,
And the level of the safety area is displayed. In the illustrated example, "CENTER MOD
"E", the board level is "LEVEL2", and the safety area is "LEVE2".
L1 ". The user U places the mobile terminal device 50 on the central area of the upper surface of the balance board BB with the display unit 51 facing upward. After that, the balance board application starts START button G
When the operation for B51 is accepted, the balance measurement is started. Further, when the balance board application accepts an operation on the button GB52, the balance board application transits to the mode selection screen shown in FIG. 6B and redoes various settings.

On the training start screen shown in FIG. 7A, a pointer P51 indicating the tilt of the balance board BB is displayed in a polar coordinate system as tilt information of the balance board BB. The reference point K51 is the center (pole) of polar coordinates. The straight line KX and the straight line KY correspond to the X axis and the Y axis shown in FIGS. 1 and 2 when the mobile terminal device 50 is placed on the central region of the upper surface of the balance board BB.
When the pointer P51 is located at the reference point K51, it indicates that the balance board BB is in the horizontal state. In addition, the inclination of the balance board BB is indicated by the distance from the reference point K51 of the pointer P51 and the deviation angle from the straight line KX or the straight line KY. It is displayed at a position far from K51.

Further, each of the circles CR51, CR52, and CR53 centering on the reference point K51 indicates a range for each level of the safety area. Circle C with the longest radius from reference point K51
The range of R51 indicates the range of the safety area of "LEVEL1: beginner". The range of the circle CR53 having the shortest radius from the reference point K51 indicates the range of the safety area of “LEVEL3: for advanced users”. Circle CR with a size between circle CR51 and circle CR53
The range of 52 indicates the range of the safety area of "LEVEL2: Intermediate level".
In order that the selected safety area can be discriminated, the range of the circle corresponding to the safety area is displayed in a display mode such as a specific color (for example, green), color intensity, gradation (brightness). This figure shows that the safety area is "LEVEL1: Beginner", and the circle CR51
Is displayed in a display mode (eg, green) as a safety area. Also in this case, for example, the closer to the reference point K51 (the inner circle range), the darker the color may be displayed. The radius of the largest circle CR51 from the reference point K51 is set to be equal to or less than (or less than) the distance corresponding to the tilt amount in the most tilted state of the balance board BB. The state where the balance board BB is most inclined means that the board of the balance board BB (board portion B
) Is on the ground.

On the training start screen, the pointer P51 moves on the polar coordinates according to the balance state of the balance board BB. Since the position of the pointer P51 in polar coordinates indicates the current inclination of the balance board BB, the pointer P51 indicates that the reference point K5 is the polar coordinate center.
The installation location of the balance board is selected so that it approaches 1 (that is, the balance board BB is substantially horizontal). Even if the installation place of the balance board BB is horizontal,
The mobile terminal device 50 placed on the upper surface of the balance board BB may be tilted. For example, when the mobile terminal device 50 is housed in a notebook type case, it may be slightly tilted. In this way, the inclination indicated by the pointer P51 affects the inclinations of both the balance board BB and the mobile terminal device 50. Therefore, here, although it is described as “the inclination of the balance board BB”, this also includes the inclination of the mobile terminal device 50.

Further, when it is determined that the balance board BB is greatly inclined on the training start screen (for example, when the pointer P51 exceeds the predetermined range (for example, the range of the circle CR51)), the balance board application is The balance measurement may not be started. FIG. 7B is a diagram showing an example of the training start screen when the pointer P51 exceeds the predetermined range. In the illustrated example, the pointer P51 has a predetermined range (for example, a circle C
It exceeds the range of R51) and the START button GB51 for starting the balance measurement.
The operation is not accepted. In this state, the balance board application accepts an operation on the START button GB51, and when the operation is accepted, it is determined that the balance board BB or the mobile terminal device 50 is tilted without starting the balance measurement. Information to be transmitted or information for instructing the START button GB51 to operate after the balance board BB or the mobile terminal device 50 is horizontal may be displayed. From this state, when the pointer P51 falls within a predetermined range (for example, the range of the circle CR51), the balance board application accepts the operation on the START button GB51 again, and when the operation is accepted, the balance measurement is started.

When it is determined that the balance board BB is largely tilted (for example, when the pointer P51 exceeds the predetermined range (for example, the range of the circle CR51)), the portable terminal device 50 is a notebook type case. Since it is housed in the portable terminal device 50, it may not be mounted horizontally with respect to the mounting surface 12a, or the sensor incorporated in the mobile terminal device 50 may be attached at an angle. Therefore, the balance board application may accept an operation on the START button GB51 even when it is determined that the balance board BB is greatly tilted. That is, the balance board application may start the balance measurement by accepting an operation on the START button GB51 even when it is determined that the balance board BB is greatly tilted on the training start screen.

On the training start screen (before START) shown in FIG. 7, the START button GB5
When the balance measurement is started by accepting the operation for 1, the screen shifts to the training start screen (after START) shown in FIG.

FIG. 8 is a diagram showing an example of the training start screen (after START) according to the present embodiment. FIG. 8A shows a training start screen when the operation on the START button GB51 is accepted. Upon accepting the operation on the START button GB51, the balance board application regards the tilt state detected by the acceleration sensor or the like at that timing as the balance board BB being in the horizontal state, and the detected tilt amount is the initial tilt amount. And perform calibration. Therefore, like the training start screen shown in FIG. 8A, when the above calibration is performed, the pointer P51 is moved to the position of the reference point K51 (the pointer P51 was originally displayed at the position of the reference point K51. If so, leave that position). Hereinafter, the tilt amount detected by the acceleration sensor or the like is corrected based on the initial tilt amount, and the tilt amount is set as the tilt amount of the balance board BB. That is, the pointer P
51 considers that the tilt state at the timing when the START button GB51 is operated is a horizontal state, and moves on the polar coordinates according to the difference from the tilt.

As described above, before accepting the operation on the START button GB51, the balance board application moves the pointer P51 according to the tilt amount detected by the acceleration sensor or the like, whereas after accepting the operation on the START button GB51, the balance board application moves the balance. The board application corrects the tilt amount detected by the acceleration sensor or the like based on the above-described initial tilt amount (that is, the tilt amount at the timing when the operation of the START button GB51 is accepted is regarded as a horizontal state and is calibrated (calibration). Pointer P according to the tilt amount)
51 Move. Therefore, the tilt information before accepting the operation on the START button GB51 is similar to what is called a level, but the tilt information after accepting the operation on the START button GB51 is the tilt state at the timing when the operation on the START button GB51 is accepted. Is different from the so-called spirit level because it is considered to be horizontal. Also, after starting training,
Since the calibration is performed with the initial tilt amount, it is possible to perform training (balance exercise) in a state in which the tilt reference of the balance board BB is intentionally deviated from the actual horizontal state.

The balance board application performs the above-mentioned calibration, starts the countdown until the start of training, and displays the countdown seconds near the center of the screen. In this figure, “3” is displayed, which indicates that less than 3 seconds have passed until the start of training. For example, the number of seconds for the countdown is set to a preset number of seconds (for example, 5 seconds), but the balance board application sets a predetermined number of seconds for the remaining countdown each time the button GB53 is operated. Add the number of seconds (for example, 5 seconds). During this countdown, the user U rides on the balance board and starts training (balance exercise). When the countdown ends, balance measurement starts and the screen changes to the training screen.

FIG. 9 is a diagram showing an example of a screen during training in the “PRACTICE” mode according to the present embodiment. As shown in (a) of FIG. 9, the balance board application is a pointer P5.
1 is moved according to the inclination amount of the balance board BB. As a result, the balance board application prompts the user U to make a balance so that the pointer P51 does not come out of the safety area (for example, the range of the circle CR51). In the balance board application, as shown in (b) of FIG. 9, the pointer P51 is displayed in the safety area (for example, the circle CR5
(1 range), or when it is determined that the safety area (for example, the range of the circle CR51) has come out, the display mode of the safety area is changed to a display mode that calls attention (for example, from green to pink). Change to color).

It should be noted that the display mode for calling attention is not limited to the color change, and may be a change to a blinking display. Further, the balance board application may change the display mode of the safety area to a display mode that calls attention only when the pointer P51 leaves the safety area.

Further, the balance board application may notify the balance state by sound. For example, the balance board application may output an electronic sound (for example, “pip, pip, pip, ...”) whose output interval is changed according to the tilt amount of the balance board BB. As an example, the balance board application shortens the output interval of the electronic sound as the tilt amount of the balance board BB increases.
The balance board application may change the volume instead of or in addition to the output interval of the electronic sound. Moreover, the balance board application may output an electronic sound (buzzer sound) of a predetermined length at the end of the training.

In this "PRACTICE" mode, even if the pointer P51 moves out of the safety area, the training (balance exercise) continues. The balance board application is "P
When the operation on the button GB54 for ending the training in the "RACTICE" mode is accepted, the balance measurement is ended. After the end, for example, after transitioning to the screen displaying the training result, the screen transitions to the training method selection screen shown in FIG. Information such as the date of training, the time of training, the mode and level of training, etc. is displayed on the screen displaying the training results.

FIG. 10 is a diagram showing an example of a screen during training in the “TIME TRIAL” mode according to the present embodiment. When the countdown is completed, the balance board app will display
As shown in (a) of No., while the pointer P51 does not come out of the safety area (for example, the range of the circle CR51), the elapsed time from the end of the countdown is measured and the measured time is displayed at the top of the screen. Let That is, the balance board application measures the time during which the user U can get on the balance board BB without displaying the pointer P51 from the safety area, and displays it on the screen during training. In other words, the balance board application is user U
On the other hand, the balance board BB is mounted while balancing so that the pointer P51 does not come out of the safety area. Then, as shown in (b) of FIG. 10, the balance board application stops the time measurement when the pointer P51 goes out of the safety area, and the measurement result (the pointer P51 does not come out of the safety area). Time) is displayed at the top of the screen. Then, the training (balance exercise) ends. At this time, the display mode of the safety area is changed from green to pink, for example.
Further, the balance board application may notify the balance state by sound, as in the “PRACTICE” mode.

After the training is completed, for example, after transitioning to a screen displaying the training result, the screen transitions to the training method selection screen shown in FIG. On the screen displaying the training results, for example, information such as training dates, measurement time (time trial) results, training modes and levels, and the like are displayed.

In addition, the balance board application is in "PRACTICE" mode and "TIME TRI".
Generate a screen that displays the training results in "AL" mode as an image and use that image as an SNS
It may have a function that can be shared by (Social Networking Service) or email.

[Configuration of mobile terminal device 50]

FIG. 11 is a block diagram showing an example of the configuration of the mobile terminal device 50 according to the present embodiment. The illustrated mobile terminal device 50 includes a display unit 51, an input unit 52, a speaker 53, a sensor 54, a communication unit 55, a storage unit 56,
And a control unit 57.

The display unit 51 is a display that displays information such as images and text, and is configured to include, for example, a liquid crystal display panel, an organic EL (Electro Luminescence) display panel, and the like. For example, the display unit 51 can display the application screens shown in FIGS. 6 to 10 (various setting screens, training start screens, training screens, etc.) under the control of the control unit 57. Further, the display unit 51 can display tilt information of the balance board BB and the like on the training start screen and the screen during training under the control of the control unit 57.

The input unit 52 is configured integrally with the display unit 51, for example, as a touch panel that detects an operation on the display screen of the display unit 51. For example, the input unit 52 receives an input by the operation of the user U by a touch operation on the display screen. The input unit 52 also outputs an input signal (for example, a signal indicating a touched position) that has been input to the control unit 57. The input unit 52 may include a mechanical operator, a microphone for inputting voice, or the like. The speaker 53 outputs electronic sound, voice, and the like under the control of the control unit 57.

The sensor 54 is configured to include a sensor that can be used to detect the amount of tilt of the mobile terminal device 50. For example, the sensor 54 is configured to include an acceleration sensor, and has three axes orthogonal to each other (
The acceleration (gravitational acceleration) in the X-axis, Y-axis, and Z-axis directions is detected. The sensor 54 outputs the detection result of the acceleration (gravitational acceleration) in the three-axis (X-axis, Y-axis, and Z-axis) directions to the control unit 57 as the detection result of the tilt amount of the mobile terminal device 50. The sensor 54 may be configured to include a gyro sensor, a magnetic sensor, an inclination sensor, or the like instead of or in addition to the acceleration sensor. The directions of the three axes of the sensor 54, which are the X axis, the Y axis, and the Z axis, are the width direction of the balance board BB and the width direction of the balance board BB when the mobile terminal device 50 is placed on the balance board BB, respectively.
It is the same as the depth direction and the height direction (X axis, Y axis, Z axis in FIG. 1).

The communication unit 55 includes, for example, mobile communication, wireless communication such as WiFi (registered trademark), and the like. The communication unit 55 executes a communication process via a communication network such as the Internet connected to the wireless communication. For example, when the image showing the training result is shared by SNS or mail, the communication unit 55 executes the communication process.

The storage unit 56 is, for example, an HDD (Hard Disk Drive) or an SSD (Sol).
id State Drive), EEPROM (Electrically Eras)

ry) and the like, various information and images processed by the mobile terminal device 50, an OS (Operati)
ng System) and applications (for example, balance board application) programs and the like are stored. The mobile terminal device 50 includes a voice output terminal (not shown), a camera, a GPS (
It may be configured to include a hardware configuration such as a Global Positioning System) receiving module.

The control unit 57 is a CPU (Central) that functions as a control center of the mobile terminal device 50.
An information processing device such as a processing unit) is provided, and the processing is executed based on the OS stored in the storage unit 56 and the program of the application (for example, the balance board application). For example, the control unit 57 has, as a functional configuration realized by executing the balance board application, an operation reception unit 571, an inclination detection unit 572, an initial inclination amount identification unit 573, a display control unit 574, and a setting unit. 575, a tilt determination unit 576, and a training processing unit 577.

The operation reception unit 571 receives various types of users U based on the input signal output from the input unit 52.
Accepts the operation (touch operation). For example, the operation receiving unit 571 receives an operation on the application screen displayed on the display unit 51. The operation on the application screen is an operation on various screens shown in FIGS. 6 to 9, for example, an operation for selecting a training method, a mode, a board level, and a safety area level, an operation for starting training, and an operation for returning to the mode selection screen. , The operation of adding the number of seconds of the countdown until the start of training, the operation of the end of training, etc.

The tilt detection unit 572 detects the tilt amount of the mobile terminal device 50 based on the detection result of the sensor 54. The amount of tilt is the amount of tilt in which direction. For example, the tilt detection unit 572 determines a value based on the acceleration in the three-axis (X-axis, Y-axis, Z-axis) directions output from the sensor 54, according to the rotation angle of the three-axis (X-axis, Y-axis, Z-axis). The calculated value is calculated as the tilt amount of the mobile terminal device 50. At this time, the tilt detection unit 572 performs correction (first correction) based on the setting of the board level (attachment state of the attachment C), the width direction (X axis direction) and the depth direction (Y axis direction) of the balance board BB. The correction (second correction) due to the difference in length, the correction (third correction) in consideration of the bending of the balance board BB due to the weight of the user U, and the like are performed. These corrections are performed when the tilt amount of the mobile terminal device 50 is regarded as the tilt amount of the balance board BB. The specific contents of the correction of these tilt amounts will be described later. The tilt detecting unit 572 also converts the corrected tilt amount into a polar coordinate system, and calculates the position of the pointer P51 in polar coordinates.

The initial tilt amount specifying unit 573 specifies the tilt amount detected at the timing when the operation receiving unit 571 receives the training start operation as the initial tilt amount. The training start operation is an operation on the START button GB51 on the training start screen shown in FIG. More specifically, the tilt amount detection timing specified as the initial tilt amount is a predetermined timing corresponding to the timing at which the operation accepting unit 571 accepts the training start operation. For example, the predetermined timing is a predetermined timing from when the operation receiving unit 571 receives the operation for starting the training to when the training (balance exercise) is started. As an example, the predetermined timing is the timing at which the detection result of the sensor 54 can be acquired in the shortest time after accepting the training start operation. For example, the initial tilt amount identification unit 573
The tilt amount based on the detection result of the sensor 54 that can be acquired in the shortest after receiving the training start operation is specified as the initial tilt amount. Immediately after the operation receiving unit 571 receives the operation for starting the training, the balance of the balance board BB may be lost due to the touch operation. Therefore, the predetermined timing may be a timing at which the detection result of the sensor 54 can be acquired after a predetermined time (for example, 0.5 seconds) has elapsed after receiving the training start operation. Hereinafter, this predetermined timing is also referred to as “initialization timing”.

Then, the initial tilt amount specifying unit 573 stores the specified initial tilt amount in the storage unit 56. After the initialization timing, the tilt detecting unit 572 corrects the tilt amount of the mobile terminal device 50 based on the detection result of the sensor 54 based on the initial tilt amount specified by the initial tilt amount specifying unit 573 (
Calibrate). This correction may be performed on the detection result of the sensor 54 or may be performed on the tilt amount of the mobile terminal device 50 detected based on the detection result of the sensor 54. Further, this correction may be performed on the corrected tilt amount after performing at least one of the first correction, the second correction, and the third correction described above.

The display control unit 574 controls the display of the application screen (see FIGS. 6 to 10) displayed on the display unit 51. For example, the display control unit 574 generates tilt information of the balance board BB based on the position of the pointer P51 in the polar coordinates calculated based on the tilt amount detected by the tilt detection unit 572, and the training start screen (FIG. 7 and FIG. 8)) or a training screen (see FIGS. 9 and 10). Specifically, in the training start screen (see FIG. 7 and FIG. 8), the display control unit 574 is before the initialization timing, so the sensor 54
The tilt information of the balance board BB is generated and displayed on the basis of the position of the pointer P51 in the polar coordinates calculated according to the tilt amount based on the detection result of. On the other hand, the display control unit 574
In the training screen (see FIGS. 9 and 10), since the initialization timing has been reached, the tilt amount based on the detection result of the sensor 54 is corrected (calibrated) based on the initial tilt amount. The tilt information of the balance board BB is generated and displayed based on the position of the pointer P51 in the calculated polar coordinates.

As described above, the display unit 51 of the mobile terminal device 50 displays the sensor 5 before the initialization timing.
The tilt information of the balance board BB can be displayed according to the tilt amount detected in 4. Further, the display unit 51 can display the tilt information of the balance board BB according to the tilt amount obtained by correcting the tilt amount detected by the sensor 54 based on the initial tilt amount after the initialization timing.

The setting unit 575 performs various setting processes in the balance board application. For example, the setting unit 575 causes the display unit 51 to sequentially display application screens for performing various settings illustrated in (a), (b), (c), and (d) of FIG. 6 via the display control unit 574. The training method, mode (exercise mode), board level, safety area level, and the like are set based on the operation of the user U on each screen received by the operation receiving unit 571.

The tilt determining unit 576 is configured to determine the position of the pointer P51 calculated by the tilt detecting unit 572 and the setting unit 5
Based on the safety area level set in 75, the pointer P51 is displayed on the polar coordinates.
It is determined whether or not the position of is within the safety area.

The training processing unit 577 uses the training method and mode (set by the setting unit 575
Exercise process), board level, safety area level, etc. For example, when the various settings made by the setting unit 575 are completed, the training processing unit 577 causes the display unit 51 to display the training start screen (see FIG. 7) for starting the balance measurement according to the settings, via the display control unit 574. . Further, the training processing unit 577
User U to the START button GB51 on the training start screen (see FIG. 7)
When the operation accepting unit 571 accepts the operation of, the training start screen (after START) is displayed on the display unit 51 via the display control unit 574, and the countdown process until the start is started.

Further, when the countdown ends, the training processing unit 577 displays “PRACTIC
The screen during training shown in FIG. 9 in the case of “E” mode and the screen during training shown in FIG. 10 in the case of “TIME TRIAL” mode are displayed on the display unit 51 via the display control unit 574. During the training, the training processing unit 577 controls the display mode of the safety information of the tilt information of the balance board BB, the electronic sound, and the like based on the determination result of the tilt determination unit 576. Further, the training processing unit 577 ends the training processing according to a predetermined condition. For example, the training processing unit 577 displays “PRACTIC
In the case of the “E” mode, when the operation receiving unit 571 receives the operation of the user U on the button GB54 (see FIG. 9) for ending the training, the training process is ended. Further, the training processing unit 577 ends the training processing when the pointer P51 goes out of the safety area in the "TIME TRIAL" mode.

[Correction of tilt amount]
Next, a specific example of the correction performed when the tilt detection unit 572 regards it as the tilt amount of the balance board BB will be described. As described above, the tilt detection unit 572 performs the correction (first correction) based on the board level setting (attachment state of the attachment C) and the width direction (X) of the balance board BB.
The correction (second correction) due to the difference in length between the axial direction) and the depth direction (Y-axis direction), and the correction (third correction) considering that the balance board BB bends due to the weight of the user U (third correction). To do.

[First correction: correction according to board level setting (attachment C attachment state)]
The maximum protrusion amount of the balance board BB (balance board BB) changes depending on the board level setting (attachment state of the attachment C).
Will change. Attachment C is not attached (board level is "LEVEL1")
However, since the protrusion height is the lowest, the maximum inclination amount (θ1) of the balance board BB is the smallest. The state in which the attachment C is inserted into the deep slit (the second groove C11B shown in FIG. 3) and attached (
When the board level is “LEVEL2”), the protrusion height is higher than that in the state where the attachment C is not attached, and the maximum tilt amount (θ2) of the balance board BB is larger than the maximum tilt amount (θ1). When the attachment C is inserted and mounted in the shallow slit (first groove C11A shown in FIG. 3) (board level is “LEVEL3”), the protrusion height is the highest and the maximum inclination amount (θ3) of the balance board BB is also the largest. Become. In this way, the maximum tilt amount changes in three stages (θ1 <θ2 <θ3) depending on the board level setting. Therefore, the tilt detection unit 572 displays the pointer P51 indicating the tilt of the balance board BB on the same polar coordinates while the maximum tilt amount changes in three steps depending on the board level setting. Is corrected so that the position of the pointer P51 (distance from the reference point K51) becomes the same on the polar coordinates.

For example, the maximum inclination amount (θ1) × α of “LEVEL1”, the maximum inclination amount (θ2) × β of “LEVEL2”, and the maximum inclination amount (θ2) × γ of “LEVEL3” are equal to each other. Such correction values α, β, γ are defined. As an example, when θ1 = 2 degrees, θ2 = 3 degrees, and θ = 4 degrees, α = 0.6, β = 0.4, and γ = 0.3 are set. The tilt detection unit 572 sets the board level correction value for the tilt amount detected by the sensor 54 (a value based on the acceleration in the three-axis (X-axis, Y-axis, Z-axis) directions output from the sensor 54). Is multiplied by. That is, in the first correction, the position of the pointer P51 in the polar coordinates is the reference point K5 as the board level has a smaller maximum tilt amount with respect to the tilt amount detected by the tilt detection unit 572.
Correction is made so that the position is far from 1 (the inclination becomes large).

The correction value described above is an example and can be set arbitrarily. For example, in the above example, the correction value α of each level is set so that the value obtained by multiplying the maximum tilt amount of each level by the correction value becomes equal.
Although the example in which β and γ are defined has been shown, the values obtained by multiplying the maximum inclination amount of each level by the correction value may not be completely the same. Further, it is not necessary to correct all levels. For example, when there is little difference in the downward protrusion height of the balance board BB due to the attachment state of the attachment C, at least a part of the levels need not be corrected. May be.

By this first correction, the display unit 51 causes the tilt amount of the balance board BB to be corrected in accordance with the tilt amount detected by the sensor 54 based on at least the board level setting (attachment state of the attachment C). Information can be displayed.

[Second correction: correction due to the difference in length between the width direction (X axis direction) and the depth direction (Y axis direction) of the balance board BB]
This correction is a correction according to the shape of the balance board BB. Specifically, the length of the balance board BB in the width direction (X axis direction) and the depth direction (Y axis direction) are different, for example,
This is a correction for representing the pointer P51 in circular polar coordinates, while the balance board BB has an elliptical shape (or a shape close to an ellipse). Since the width direction (X-axis direction) is longer than the depth direction (Y-axis direction) and the maximum tilt amount is smaller, the amount of change in the width direction (X-axis direction) increases in the X-axis direction. It is necessary to stretch (increase) and give. That is, in the second correction, the position of the pointer P51 in polar coordinates in the X-axis direction, which is longer than the Y-axis direction in which the length is short, with respect to the tilt amount detected by the tilt detection unit 572, is the reference point K5.
Correction is made so that the position is far from 1 (the inclination becomes large).

FIG. 12 is an explanatory diagram of the second correction according to this embodiment. As shown in (a) of FIG. 12, the balance board BB has a shape BCR extending in the X-axis direction with respect to a circle CR indicated by a broken line. The circle CR shown in this figure is shown for comparison of shapes and is not related to the configuration of the balance board BB. In the example shown in (a) of FIG. 12, a rightward region (right half region) that is the positive direction of the X axis and a leftward region (left half region of the X axis) that is the positive direction of the X axis from the center of the balance board BB. In each of the areas), the correction value is determined by dividing into three areas E1, E2, and E3 in the direction from the center side to the edge of the board along a line segment orthogonal to the X axis. Each of the areas E1, E2, E3 in the right half area and E1, E2 in the left half area
, E3 regions are line-symmetrical with respect to the line segment in the Y-axis direction at the center of the balance board BB.

In the area E1, the curve of the arc of the shape BCR of the balance board BB is bent more gently than the curve of the arc of the circle CR (that is, the shape extending from the circle CR in the X-axis direction). Therefore, the inclination detection unit 572 corrects the value based on the acceleration in the X-axis direction in the detection result of the sensor 54 in the direction of increasing it. For example, the correction value ER1 = 1.2 is set in the area E1, and the tilt detecting unit 572 determines the tilt amount in the X-axis direction (value based on the acceleration in the X-axis direction) detected by the sensor 54. The “correction value ER1 = 1.2” is multiplied.

In the area E2, the curve of the arc of the shape BCR of the balance board BB is bent more gently than the curve of the arc of the circle CR than in the area E1 (that is, the shape extending further in the X-axis direction than the circle CR). ). Therefore, the tilt detection unit 572 is configured to detect X of the detection results of the sensor 54.
The value based on the acceleration in the axial direction is corrected so as to be further increased than the area of E1. For example,
In the area of E2, “correction value ER2 = 1.4” is set, and the inclination detecting unit 572 “corrects” the inclination amount in the X-axis direction (value based on the acceleration in the X-axis direction) detected by the sensor 54. Value E
R2 = 1.4 "is multiplied.

In the area E3, the curve of the arc of the shape BCR of the balance board BB is more curved than the curve of the circle of the circle CR, and therefore the inclination detection unit 572 determines the value based on the acceleration in the X-axis direction among the detection results of the sensor 54. Correct in the direction of decreasing. For example, in the area of E3, “correction value ER3
= 0.8 ”, and the inclination detection unit 572 sets the“ correction value ER3 = 0.8 ”to the inclination amount in the X-axis direction (value based on the acceleration in the X-axis direction) detected by the sensor 54. To multiply.

By performing the second correction, the tilt amount of the balance board BB having an elliptical shape (or a shape close to an ellipse) having different lengths in the width direction (X axis direction) and the depth direction (Y axis direction). Can be converted into the position of the pointer P51 on the circular polar coordinates.

Note that the correction values of the areas E1, E2, and E3 described above are examples, and the balance board B
It can be arbitrarily determined according to the shape of B and the like. In addition, in the example shown in FIG.
The example in which the correction value is determined by dividing each of the right half area and the left half area of the balance board BB into three has been described, but the number of divisions of the area in which the correction value is determined can be arbitrarily determined.

In the example shown in FIG. 12A, the line segment orthogonal to the X-axis is divided into three regions E1, E2, and E3 in the direction from the center to the end of the board. The direction and shape to be performed are not limited to this. FIG. 12B is a diagram showing a modified example of how to divide the area for setting the correction value when performing the second correction. As shown in FIG. 12B, the correction value may be set in each of the areas E1, E2, and E3 divided by the line segment that extends radially from the center of the balance board BB.

In the above example, the first length L1 in the width direction (X axis direction) is smaller than the second length L2 (reference) with the second length L2 in the depth direction (Y axis direction) of the balance board BB as a reference. Although the example of correcting the amount of inclination in the X-axis direction based on the long length has been described, the first length L1 in the width direction (X-axis direction) is described.
May be used as a reference. For example, the tilt detection unit 572 may determine the balance board BB in the depth direction (Y
The amount of inclination in the Y-axis direction may be corrected based on the fact that the second length L2 in the axial direction is shorter than the first length L1 (reference) in the width direction (X-axis direction).

Due to this second correction, the display unit 51 causes the amount of tilt detected by the sensor 54 to be at least the length in the width direction (X-axis direction) or the second length in the depth direction (Y-axis direction) of the balance board BB. The tilt information of the balance board BB can be displayed according to the tilt amount corrected based on For example, the display unit 51 may tilt the longer one of the lengths of the balance board BB in the width direction (X-axis direction) and the depth direction (Y-axis direction) in comparison with the shorter one. The tilt information of the balance board BB can be displayed according to the corrected tilt amount.

[Third correction: correction considering that the balance board BB bends due to weight]
Since the balance board BB is bent due to the weight of the user U and may affect the tilt amount of the balance board BB, the tilt detection unit 572 corrects the tilt amount according to the user U weight. For example, the heavier the body, the more the balance board BB is bent in the width direction (X-axis direction), and the edge of the balance board BB is more likely to reach the ground even if the tilt amount when the balance board BB is tilted in the X-axis direction is small. . In other words, the heavier the weight, the width direction of the balance board BB (X axis direction)
Is long. Therefore, the inclination detection unit 572 corrects the value based on the acceleration in the X-axis direction in the detection result of the sensor 54 so as to increase as the weight becomes heavier. That is,
In the third correction, the tilt amount detected by the tilt detection unit 572 is corrected so that the position of the pointer P51 in polar coordinates is farther from the reference point K51 (the tilt becomes larger) as the weight is heavier.

As an example, if the weight is less than 10 kg, the correction value WR corresponding to the weight is “100” and 10 k.
"95" when g or more and less than 20 kg, "90" when 20 kg or more and less than 30 kg, ..., 8
"60" for 0 kg or more and less than 90 kg, "55" for 90 kg or more and less than 100 kg, 10
It is specified as "50" for 0 kg or more. The tilt detection unit 572 determines the amount of tilt in the X-axis direction detected by the sensor 54 according to the weight of the user U (a value based on the acceleration in the X-axis direction).
Is multiplied by “100 / correction value WR”. For example, in the above example, the correction value WR of the user U who weighs 100 kg or more is “50”. Therefore, the tilt amount is doubled for the user U who weighs 100 kg or more. On the other hand, the correction value WR of the user U whose weight is less than 10 kg is "
100 ". Therefore, in the case of the user U who weighs less than 10 kg, the tilt amount is multiplied by 1, and no correction is performed.

The correction value described above is an example and can be set arbitrarily. For example, in the above example, the case where the weight is less than 10 kg is not corrected, but the range of the weight that is not corrected is not limited to the weight less than 10 kg. Further, the correction may be performed on all the weights. Further, the division of the body weight for which the correction value is set is not limited to 10 kg and can be arbitrarily set. The correction value WR may be different depending on the board level even if the weight is the same.

Note that the weight of the user U can be input from the application screen for registering the user information when the balance board application is first activated, for example. For example, the setting unit 5
When the balance board application is first activated, 75 causes the display unit 51 to display a user information registration screen via the display control unit 574. Then, when the operation receiving unit 571 receives the weight information input on the user information registration screen, the setting unit 575 transmits the received weight information to the user U who uses the balance board application on the mobile terminal device 50. The weight information is stored in the storage unit 56.

With this third correction, the display unit 51 can display the tilt information of the balance board BB in accordance with the tilt amount detected by the sensor 54 and corrected based on at least the weight of the user U.

[Display processing of tilt information]
Next, referring to FIG. 13, the balance board B executed by the control unit 57 of the mobile terminal device 50.
The operation of the B tilt information display processing will be described.
FIG. 13 is a flowchart showing an example of tilt information display processing of the balance board BB according to the present embodiment. The tilt information display process shown in this figure is shown in FIG. 7 after the setting of the training method, mode (exercise mode), board level, safety area level, etc. is completed on the application screen of various settings shown in FIG. It is started in response to the transition to the start screen (before START).

The control unit 57 acquires the amount of tilt detected by the sensor 54 in a predetermined detection cycle. For example, the control unit 57 acquires the detection result of the acceleration (gravitational acceleration) in the directions of the three axes (X axis, Y axis, and Z axis) detected by the sensor 54 as the detection result of the tilt amount of the mobile terminal device 50 ( Step S101).

Next, the control unit 57 performs a correction (first correction) on the tilt amount acquired in step S101 according to the set board level. For example, the controller 57 sets the board level to "L.
The correction value α in the case of “EVEL1”, the correction value β in the case of the board level “LEVEL2”, the correction value γ in the case of the board level “LEVEL3”, and the inclination amount detected by the sensor 54 ( (Value based on acceleration in the three axes (X-axis, Y-axis, Z-axis) output from the sensor 54)
Is multiplied by (step S103).

Subsequently, the control unit 57 performs a correction (second correction) according to the shape of the balance board on the tilt amount corrected in step S103. For example, the control unit 57 sets “correction value ER1 = 1.2” in the area E1 shown in FIG. 12A and “correction value ER2 = 1.4” in the area E2.
In the area of E3, “correction value ER3 = 0.8” is multiplied by the corrected tilt amount in the X-axis direction (value based on acceleration in the X-axis direction) corrected in step S103 (step S105).

Further, the control unit 57 performs correction (third correction) according to the weight of the user U on the tilt amount corrected in step S105. For example, the control unit 57 sets “100 / correction value WR” to the corrected tilt amount in the X-axis direction (value based on acceleration in the X-axis direction) corrected in step S105 based on the correction value WR according to the weight. Is multiplied by (step S107).

Next, the control unit 57 determines whether or not the training has been started (step S10).
9). For example, the control unit 57 performs a training start operation (for example, the START button GB shown in (a) of FIG. 7) before acquiring the tilt amount detected by the sensor 54 in the previous detection cycle.
If the (operation for 51) has already been performed, it is determined that the training has been started. On the other hand, the control unit 57 determines that the training has not been started when the training start operation is not performed before the tilt amount detected by the sensor 54 is acquired in the previous detection cycle.

If it is determined in step S109 that training has not started (NO),
The control unit 57 determines whether a training start operation has been performed (step S111).
For example, the control unit 57 performs a training start operation between the acquisition of the tilt amount detected by the sensor 54 in the previous detection cycle and the acquisition of the tilt amount detected by the sensor 54 in the current detection cycle ( (For example, operation on the START button GB51 shown in FIG. 7A)
If it is determined that the training start operation has been performed. On the other hand, the control unit 57 acquires the amount of tilt detected by the sensor 54 in the previous detection cycle, and then the sensor 5 in the current detection cycle.
If the training start operation is not performed before the tilt amount detected in 4 is acquired, it is determined that the training start operation is not performed.

When it is determined in step S111 that the training start operation has not been performed (N
O), the control unit 57 generates the tilt information of the balance board BB according to the corrected tilt amount corrected in step S105 and causes the display unit 51 to display the tilt information. Specifically, as shown in FIG. 7, the control unit 57 causes the pointer P51 indicating the tilt amount of the balance board BB to be displayed on the polar coordinates according to the tilt amount detected by the sensor 54 (step S117).

On the other hand, when it is determined in step S111 that the training start operation is performed (Y
ES), the control unit 57 specifies the tilt amount detected at the initialization timing after the training start operation (the tilt amount detected by the sensor 54 in the current detection cycle) as the initial tilt amount, and the storage unit 56. Save to. For example, the corrected tilt amount corrected in step S107 is specified and stored as the initial tilt amount (step S113).

Then, the control unit 57 corrects (calibrates) the corrected tilt amount corrected in step S107 (the tilt amount after correction of the tilt amount detected at the initialization timing) based on the initial tilt amount (step S115). . For example, the control unit 57 performs correction (calibration) so that the corrected tilt amount corrected in step S107 (corrected tilt amount of the tilt amount detected at the initialization timing) becomes the reference point K51 (center) of polar coordinates. ) (Step S115). Then, the control unit 57 generates tilt information of the balance board BB in which the position of the pointer P51 indicating the corrected tilt amount corrected based on the initial tilt amount in step S115 is the reference point K51 (center) of the polar coordinates. It is displayed on the display unit 51 (see (a) of FIG. 8) (step S117).

Once it is determined in step S111 that the training start operation has been performed, thereafter, it is determined in step S109 that training has been started (YES).
In this case, since the initial tilt amount is already stored, the control unit 57 proceeds to step S115 and corrects the corrected tilt amount corrected in step S107 based on the initial tilt amount stored in the storage unit 56. . That is, after the training start operation is performed, the tilt amount detected at the initialization timing is corrected to the tilt amount calibrated so as to become the reference point K51 of the polar coordinates. Then, the controller 57 corrects the tilt amount based on the initial tilt amount (corrected tilt amount).
The tilt information of the balance board BB is generated in accordance with the display information and displayed on the display unit 51 ((b in FIG. 8).
), FIG. 9 and FIG. 10) (step S117).

In the example of the tilt information display processing of the balance board BB shown in FIG. 13, the control unit 57
The first correction, the second correction, and the third correction are performed both before and after the training start operation, but before the training start operation is performed, the first correction and the second correction are performed. The correction and part or all of the third correction may not be performed. For example, the control unit 57 performs the training start operation (YES in step S109 or step S111).
Only, the first correction, the second correction, and the third correction may be performed before or after step S115.

Further, the order of the first correction, the second correction, and the third correction may be exchanged. Further, only some of the first correction, the second correction, and the third correction may be performed, or all of them may not be performed. For example, when the amount of change in the downward projection height of the balance board BB that changes depending on the board level setting (attachment state of the attachment) is small, the first correction may not be performed. Further, when the difference in length between the width direction (X axis direction) and the depth direction (Y axis direction) of the balance board BB is small, the second correction may not be performed. The third correction may not be performed when the amount of bending is small due to the material and size of the balance board BB. The third correction is board level (
The presence or absence of the correction may be determined depending on the attachment state of the attachment C). For example, when the attachment C is not attached, the balance board BB is most likely to reach the ground when the balance board BB is bent due to the weight of the user U. Therefore, the third correction may be performed only on the board level (“LEVEL1”) in which the attachment C is not mounted. Alternatively, the third correction may be performed only when the board levels are “LEVEL1” and “LEVEL2”.

[Summary of Embodiments]
As described above, the exercise system Sys of the present embodiment includes the balance board BB and the mobile terminal device 50 (an example of a plate-shaped terminal device).
The balance board BB includes a mounting portion 12 and a protruding portion 11. The mounting portion 12 is provided in the central region of the upper surface Ba of the board portion B. The mounting unit 12 is capable of mounting the mobile terminal device 50. The protruding portion 11 protrudes with respect to the upper surface Ba of the board portion B at a part or the whole of the periphery of the mounting portion 12. The projecting portion 11 is configured to include four wall surfaces 11w that face each of the four side surfaces 50w of the mobile terminal device 50 in a state where the mobile terminal device 50 is mounted on the mounting portion 12.
The mobile terminal device 50 has a plate shape, and the built-in sensor 54 allows the mobile terminal device 50 (the mobile terminal device 50).
) Is provided with a display unit 51 capable of displaying tilt information. The display unit 51 can display the tilt information of the balance board BB by mounting the mobile terminal device 50 (own device). The plate-shaped portable terminal device 50 has a flat main body, and is, for example, a device that employs a full-screen display corresponding to a touch operation. The plate-shaped portable terminal device 50 may have some irregularities such as operation buttons or a curved surface.

According to the above configuration, only by placing the mobile terminal device 50 on the placing portion 12, the user U, while riding on the upper surface Ba of the board portion B, the tilt information of the balance board BB displayed on the display portion 51. Can be seen. Accordingly, the exercise system Sys and the balance board BB can easily support the balance exercise of the user U. In addition, for example, a balance board equipped with a controller having the same function as the mobile terminal device 50 including the sensor 54 and the display unit 51 can be used by a plurality of users U, but the exercise result (measurement result) is not included in the data. However, since the mobile terminal device 50 mounted on the mounting unit 12 can be replaced, for example, even when a plurality of users U share the same balance board BB, each user U himself The balance terminal BB can be used by mounting the portable terminal device 50 of No. 1 on the mounting unit 12. Then, the exercise result (measurement result) can be recorded in the own mobile terminal device 50.

Further, when the user U rides on the balance board BB and performs a balance exercise, even if the portable terminal device 50 mounted on the mounting portion 12 tries to slide on the mounting portion 12 due to the inclination of the balance board BB. Alternatively, even if the mobile terminal device 50 slides, the side surface of the mobile terminal device 50 hits the wall surface of the protrusion 11. Thereby, the mobile terminal device 50 can be suppressed from sliding on the mounting portion 12, and the mobile terminal device 50 can be prevented from falling from the balance board BB.
Further, it is possible to prevent the mobile terminal device 50 placed on the placing section 12 from rotating on the placing section 12. Accordingly, when the user U rides on the balance board BB and performs a balance exercise, it is possible to prevent the display section 51 of the mobile terminal device 50 from being difficult to see due to the orientation of the mobile terminal device 50 changing.

In addition, when the user U rides on the balance board BB and performs a balance exercise, when the balance is lost on the balance board BB or when the user U's foot is placed on the balance board BB, the user U mounts it on the placing part 12. There is a possibility of stepping on the mobile terminal device 50 placed. On the other hand, in the balance board BB, the projecting portion 11 projects from the upper surface Ba of the board portion B, so that the user U
It is possible to physically and psychologically prevent a person from accidentally stepping on the mobile terminal device 50. What can be physically suppressed includes, for example, that the foot of the user U hits the protruding portion 11 to prevent the foot of the user U from reaching the mobile terminal device 50. What can be psychologically suppressed is, for example,
Including that the user U recognizes the presence of the protrusion 11 can take care so that the user U does not step on the inside of the protrusion 11 (the mounting portion 12).
Further, even when the user U steps on the portable terminal device 50 placed on the placing portion 12, the load from the user U can be dispersed by the protruding portion 11, so that compared with the case where the protruding portion 11 is not provided, The force applied to the mobile terminal device can be reduced.

In addition, when the user U rides on the balance board BB to perform a balance exercise, the user U keeps his / her balance on the balance board BB and keeps his / her feet open so that the upper surface B of the board portion B can be maintained.
Place both feet on a. Therefore, even if the mobile terminal device 50 is arranged in the central region of the upper surface Ba of the board portion B, it is possible to prevent the mobile terminal device 50 from being stepped on by the foot of the user U.
Further, since the mobile terminal device 50 is arranged in the central region of the upper surface Ba of the board portion B, the center of gravity of the mobile terminal device 50 placed on the placing portion 12 is located near the center of the balance board BB.
Therefore, it is possible to prevent the center of gravity of the balance board BB from being displaced in the front-rear direction and the left-right direction due to the weight of the mobile terminal device 50.

Further, in the balance board BB of the present embodiment, the projecting portion 11 includes four corner portions 11F (an example of four corners) around the mounting portion 12, and each of the four corner portions 11F of the projecting portion 11 is
The mobile terminal device 50 has two wall surfaces facing two adjacent side surfaces of the mobile terminal device 50 when the mobile terminal device 50 is mounted on the mounting portion 12.

According to the above configuration, the four corners of the portable terminal device 50 placed on the placing portion 12 are connected to the four corners of the protruding portion 11.
It can be supported by each of the corners 11F. Therefore, when the user U rides on the balance board BB and makes a balance exercise, the mobile terminal device can be held on the mounting portion 12.

Further, in the balance board BB of the present embodiment, the projecting portion 11 does not surround the entire mounting portion 12. In other words, the non-projecting portion 13 is provided around the mounting portion 12. Further, in the periphery of the mounting portion 12, instead of the non-projecting portion 13, the upper end 11e of the projecting portion 11 (an example of the upper portion).
A lower low region portion (an example of a low region) lower than that may be formed.

According to the above configuration, in the state where the mobile terminal device 50 is placed on the placing section 12, the placing section 1
It is possible to expose a part of the side surface of the mobile terminal device 50 through the gap (non-projecting portion 13) not surrounding the periphery of 2 or the gap of the protruding portion 11 due to the low region portion. The user U can put his / her finger in this gap and hang it on the side surface of the mobile terminal device 50. In other words, by providing a gap in the projecting portion 11 that surrounds the mounting portion 12, the user U can insert his / her fingers from the gap in the projecting portion 11 and hook it on the side surface of the mobile terminal device 50. This makes it easy to take out the mobile terminal device 50 placed on the placing portion 12. The protrusion 11
The gap (non-projecting portion 13) may be a space in which the fingers of the user U can reach the side surface of the mobile terminal device 50 from the outside of the projecting portion 11. Therefore, for example, outside the periphery of the mounting portion 12 where the protrusion 11 is provided, the protrusion 11 is projected to the upper surface Ba of the board portion B and is connected to both ends of the gap of the protrusion 11 similarly to the protrusion 11. Therefore, a mode including a wall portion that surrounds the gap of the protruding portion 11 from the outside (the wall portion that protrudes with respect to the upper surface Ba of the board portion B as with the protruding portion 11 is connected to both ends of the gap of the protruding portion 11 Even when the gap of the portion 11 is surrounded from the outside), the protruding portion 11 does not surround the entire periphery of the mounting portion 12. The wall portion that surrounds the gap of the protrusion 11 from the outside may be formed integrally with the protrusion 11, or may be formed separately from the protrusion 11. In the aspect including the wall portion, the fingers of the user U can enter the inside of the wall portion from above to reach the side surface of the mobile terminal device 50 through the gap of the protrusion 11.

Further, in the balance board BB of the present embodiment, the mounting portion 12 is formed with a mounting surface 12a that suppresses slippage of the mounted mobile terminal device 50. The mounting surface 12a of the mounting portion 12 is located lower than the upper surface Ba of the board portion B and the low region portion (or the non-projecting portion 13). Specifically, the mounting surface 12 a that suppresses slippage of the mobile terminal device 50 is the slip suppression sheet 122.
It is composed by. As an example of forming such a mounting surface 12a, the slip suppressing sheet 122 is formed of a material (rubber sheet or the like) having a friction coefficient larger than that of the material of the base portion 121, or the material of the base portion 121. The surface of the slip suppression sheet 122 may be formed to have irregularities regardless of the difference.

According to the above configuration, when the user U takes out the portable terminal device 50 placed on the placing portion 12 by inserting the finger into the gap between the non-protruding portion 13 and the protruding portion 11 formed by the low area portion, the user U puts the finger on the placing portion 12. It is possible to prevent it from being caught on the placing portion 12. Thereby, damage to the mounting surface 12a can be suppressed. In particular, when the mounting surface 12a of the mounting portion 12 is composed of the slip suppressing sheet 122,
The side surface of the slip prevention sheet 122 is not exposed from the gap of the protrusion 11. Therefore, when the mobile terminal device 50 is taken out, it is possible to prevent the fingers of the user U from being caught by the slip prevention sheet 122. As a result, it is possible to prevent the slip prevention sheet 122 from being damaged or peeling off from the base portion 121 of the mounting portion 12.

Further, in the balance board BB of the present embodiment, the mounting surface 12a of the mounting portion 12 is located lower than the upper surface Ba of the board portion B.

According to the above configuration, the balance board BB does not project the protruding portion 11 from the upper surface Ba of the board portion B by the height of the protruding portion 11 from the mounting surface 12a, but does not project the upper surface Ba of the protruding portion 11.
The height from can be suppressed. As a result, it is possible to prevent the protrusion 11 from being caught on the foot during training (balance exercise).

Further, in the balance board BB of the present embodiment, the board portion B is configured by separately forming the board body B1 and the mounting portion 12. Further, a hollow portion 21 associated with resin molding is formed in the center of the board body B1. The mounting portion 12 is configured as a lid (lid member B2) that closes the hollow portion. Further, a fitting portion is provided on the board body B1 and the mounting portion 12, and the fitting portion is configured to be fitted, so that the board body B1 and the mounting portion 12 are integrated.

According to the above configuration, since the mounting portion 12 also serves as the lid that closes the hollow portion 21 of the board body B1, it is not necessary to separately prepare a lid that closes the hollow portion 21, and the number of components of the balance board BB can be reduced. Can be reduced. In addition, since the insertion hole 29 and the protrusion (an example of a fitting portion) are provided in the board body B1 and the mounting portion 12, the lid member B2 can be easily positioned with respect to the board body B1 when these are fitted together. . The shape of the fitting portion is arbitrary.

Further, in the balance board BB of the present embodiment, when the side direction of the user U in use is the width direction (X axis direction) and the direction orthogonal to the width direction is the depth direction (Y axis direction), the width direction The first length L1 of the board portion B at the second position is the second length L2 of the board portion B in the depth direction.
Longer than. The mounting portion 12 is the mobile terminal device 5 when viewed from the thickness direction of the mobile terminal device 50.
One side of 0 or one side of the display unit 51 of the mobile terminal device 50 is formed to be placed in a state of being parallel or substantially parallel to the width direction or the depth direction.

According to the above configuration, the display unit 51 of the mobile terminal device 50 placed on the placement unit 12 does not tilt obliquely with respect to the width direction (left-right direction) or the depth direction (front-back direction). For this reason, when the user U uses the balance board BB, the user U of the mobile terminal device 50 is placed on the upper surface Ba of the board portion B so that both feet (or both arms) of the user U are aligned in the width direction. The display unit 51 becomes easy to see.

Do not tilt diagonally with respect to the direction (front-back direction). For this reason, when the user U uses the balance board BB, in a state where both feet (or both arms) of the user U are arranged on the upper surface Ba of the board portion B so as to be aligned in the direction of the first major axis MA1, The display unit 51 of the mobile terminal device 50 becomes easy to see.

In the balance board BB of the present embodiment, the display unit 51 of the mobile terminal device 50 is

Can be displayed. It should be noted that the correction for making the longer inclination incline in comparison with the shorter inclination is, in other words, a correction according to the shape of the balance board BB. Furthermore, a correction according to the set board level or a correction according to the weight of the user U may be added to the correction of the tilt amount.
That is, the display unit 51 of the mobile terminal device 50 placed on the balance board BB formed in an elliptical shape having a long diameter (L1) and a short diameter (L2) is corrected and set according to the shape of the balance board BB. The tilt information of the balance board BB can be displayed according to the tilt amount corrected by at least one of the correction according to the board level and the correction according to the weight of the user U.

The tilt information of the balance board BB displayed in 1 can be visually recognized. Accordingly, the exercise system Sys and the balance board BB can easily support the balance exercise of the user U. Also,
When the balance measurement is started, the tilt amount can be initialized and calibrated while the portable terminal device 50 is placed on the balance board BB. Therefore, the horizontal state of the place where the balance board BB is installed, the degree of tilt of the balance board, and the like. Even if the presence / absence, the horizontal degree with respect to the balance board BB when the mobile terminal device 50 is placed on the balance board BB, the detection accuracy of the tilt amount in the mobile terminal device 50 (the detection accuracy of the sensor 54), etc. are not so important, the balance Board BB
You can do balance exercise using. For example, the mobile terminal device 50 starts the training process assuming that the mounted balance board BB is not tilted (the tilt is zero) even if the balance board BB is physically tilted. It is also possible to perform training (balance exercise) in a state in which the reference of the inclination of the balance board BB is intentionally shifted from the actual horizontal state. In this respect, it is different from the one in which the amount of tilt is measured by placing it on the object to be measured after calibration (so-called level).

In addition, in the mobile terminal device 50 of the present embodiment, the display unit 51 can display a pointer P51 whose distance from the reference point K51 indicates tilt information of the balance board BB.
