Description

  The present invention relates to an exercise support apparatus used for improving an exercise function, restoring an exercise function, or the like.

Various types of exercise support devices have been developed for the purpose of improving motor function or restoring motor function. For example, in the “Badminton Coaching Board for Special Training” described in Patent Document 1, when the coach presses the switch, an arrow is displayed so that the player moves in that direction, and the player performs a practice practice of hitting with a racket. Immediately after that, he rushed back to a specific position (center of the court).
According to the coach board described in Patent Document 1, a player learns not only from the head but also from the player's own body (body) as to the attitude of the athlete and the manner in which the athlete operates. In other words, you will receive special training, and the coach will not feel the fatigue as much as the left, so you can give a long-time, accurate and warm instruction.

In addition, the “rehabilitation support system and program” described in Patent Document 2 captures an image captured by a video camera, displays a red circle in the image, and the captured patient's gloves have a preset time. The red circle is changed to the black circle in the state where they are continuously overlapped.
According to the rehabilitation support system described in Patent Literature 2, it is possible to construct a system that includes entertainment, and it is possible to continue the willingness of patients with higher brain dysfunction to perform rehabilitation.

Japanese Patent Laid-Open No. 52-2627 JP 2006-325740 A

However, in the badminton coach training board described in Patent Document 1, the player moves in accordance with the direction of the arrow, but since the player moves from the destination to the specific position in the center of the court, the next movement returns Just move in the direction of the arrow. Therefore, the player only moves mechanically.
In addition, since the rehabilitation support system described in Patent Document 2 only overlaps the displayed red circle, the patient simply moves the hand mechanically as in Patent Document 1.
As described above, in the conventional exercise support devices described in Patent Documents 1 and 2, although training of exercise ability and dynamic visual acuity is performed, if only the direction is determined, it moves only in that direction. It is difficult to improve the ability to react instantly.
In competitions, you must choose your reaction to your opponent's movements. This is referred to as a selective reaction task. The athlete (athlete) is in a state where this selective reaction task is always imposed during the competition. Therefore, it is preferable that the exercise support apparatus continuously presents the selection reaction task.

  Therefore, the present invention provides an exercise support apparatus that can improve the ability to respond to a situation change by not only improving the dynamic visual acuity but also continuously presenting selective response tasks to the trainee. Objective.

  The exercise support apparatus according to the present invention operates from a plurality of detection means for detecting a trainee's movement, a display means for guiding the trainee's movement direction with an arrow, and a detection means based on the display means. An arrow indicating the direction to the previous target detection means is displayed, and when the target detection means detects the movement of the trainee, the target detection means is used as the next base point to the next target detection means. And a control means for displaying an arrow indicating the direction.

  According to the exercise support apparatus of the present invention, when the control means displays on the display means an arrow indicating the direction from the detection means as the base point to the target detection means of the operation destination, the direction in which the trainee is guided by the arrow To work. When the trainee operates, the detection means detects it. When the target detection means detects the movement of the trainee, the control means sets the target detection means as the next base point. And a control means displays the arrow which shows the direction to the detection means of the next objective. Thus, even if the arrows are in the same direction, the base point changes each time it moves, so that the target detection means changes. Therefore, in the exercise support device of the present invention, the arrow indicates the relative direction, and the situation can be changed every moment.

  The control means preferably displays an arrow indicating a direction to the target detection means adjacent to the detection means as the base point. By setting the arrow in the direction toward the adjacent detection means, the types of arrows can be reduced.

  When the detection means are arranged in a matrix, the direction of the arrow can be standardized to 8 directions at the maximum.

  When the detection means is formed by a switch pressed by the trainee, the motion of the trainee can be detected with a simple configuration.

It is desirable that the control means measures the time from when the arrow is displayed until the target detection means detects the motion of the trainee.
By measuring the time required for the motion of the trainee by the control means, statistical information from when the arrow is displayed until the target sensing means detects the motion of the trainee can be obtained. It is possible to objectively evaluate the degree of improvement and the degree of recovery of athletic ability.

  In the exercise support device of the present invention, the base point changes every time and the arrow indicates the relative direction, so the target detection means changes. Therefore, since the exercise support apparatus of the present invention can change the situation every moment, it not only improves the dynamic visual acuity but also responds to the situation change by continuously presenting the selection reaction task to the trainee. Capability can be improved.

An exercise support apparatus according to an embodiment of the present invention will be described with reference to the drawings.
The exercise support apparatus 10 illustrated in FIG. 1 includes a monitor device 11, an operation panel 12, and a control device 13.

The monitor device 11 functions as a display means for guiding the operating direction to the trainee using arrows. As the monitor device 11, a liquid crystal display, a plasma display, an organic EL display, a light emitting diode display, or the like can be used.
The operation panel 12 includes switches 121 arranged in a matrix and a pedestal portion 122 that supports the switches 121.
The switch 121 is a push button that functions as a detection unit that detects the operation of the trainee when pressed by the trainee. The switches 121 are arranged in three rows of three switches that are large enough to be pressed by the palm or the little finger side of the fist, and a total of nine switches 121 are arranged. The pedestal part 122 is formed in a rectangular shape having a side of about 50 cm.

The control device 13 is a computer to which a keyboard KB and a mouse (not shown) are connected as input means. The control device 13 functions as control means by causing a computer to run an exercise support program.
As shown in FIG. 2, the control device 13 includes direction control means 131, determination means 132, time measurement means 133, and calculation means 134.

The direction control means 131 determines the direction from the switch 121 as the base point to the target switch 121 that is the operation destination, and displays the direction as an arrow on the monitor device 11. In the present embodiment, an arrow requesting 15 operations is presented for one set, which is one training.
The display time of the arrow can be changed by setting. If the display time of the arrow is short, the display disappears instantaneously, and it is necessary to memorize the direction indicated by the arrow, so that the difficulty of training can be increased. If the display time of the arrow is long, the trainee can see the arrow slowly and has time to think, so the difficulty of training can be reduced.

The determination unit 132 determines whether or not the switch 121 pressed by the trainee is correct based on the information on the switch 121 indicated by the arrow from the direction control unit 131 and the information on the switch 121 from the operation panel 12. If the switch 121 is pressed by mistake, the determination unit 132 determines that the switch has been pressed incorrectly and cancels the trainee's press. The determination unit 132 can record an erroneous press.
The time measuring means 133 measures the time until the target switch 121 is selected and pressed after the arrow is displayed on the monitor device 11 (hereinafter, this time is referred to as a selected reaction time), and the monitor device 11 It has a function to display. The calculation means 134 has a function of calculating the difference in the selected reaction time for each number of exercises and displaying it on the monitor device 11.

The operation and use state of the exercise support apparatus according to the embodiment of the present invention configured as described above will be described with reference to the drawings.
First, as shown in FIG. 3A, the center switch 121 (“5”) among the nine switches 121 (“1” to “9”) is a base point at the start of training. When the trainee presses the center “5” switch 121, the trainer starts.

If the central switch 121 is the base point, the adjacent switch 121 is the target switch 121, and the remaining eight "1" to "4" and "6" to "9" are targeted.
Accordingly, the direction control unit 131 randomly selects one of the eight directions indicating the eight switches 121 (“1” to “4”, “6” to “9”). In FIG. 3A, an arrow pointing upward to the right with the direction control unit 131 setting the switch 121 of “3” as the target switch 121 is displayed.

The trainee looks at the arrow pointing to the upper right on the monitor device 11 and presses the “3” switch 121 located on the upper right with reference to the center switch 121.
The determination unit 132 compares the information indicating the “3” switch 121 from the direction control unit 131 with the information indicating the switch 121 from the operation panel 12 pressed by the trainee. If they match, the time measuring means 133 measures the selected reaction time from the display of the arrow until the target switch 121 ("3" switch 121) is pressed.
Next, the direction control means 131 uses the “3” switch 121 as the target switch 121 as a base point.

  If “3” switch 121 is the base point, adjacent switches 121 are targeted for “2”, “5”, and “6”. The direction control means 131 randomly selects one direction from the directions to the three switches 121. In FIG. 3 (b), an arrow heading downward is displayed in which the direction control means 131 uses the “6” switch 121 as the target switch 121.

The trainee looks at the arrow pointing directly downward displayed on the monitor device 11, and presses the “6” switch 121 located right below with reference to the switch 121 diagonally to the upper right.
The determination unit 132 compares the information indicating the “6” switch 121 from the direction control unit 131 with the information indicating the switch 121 from the operation panel 12 pressed by the trainee. If they match, the time measuring means 133 measures the selected reaction time from the display of the arrow to the pressing of the target switch 121 ("6" switch 121).
Next, the direction control means 131 uses the “6” switch 121 as the target switch 121 as a base point.

  If the switch 121 of “6” is the base point, the adjacent switches 121 are targeted for “2”, “3”, “5”, “8”, and “9”. The direction control means 131 randomly selects one direction from the directions to the five switches 121. In FIG. 3C, an arrow pointing upward to the left with the direction control unit 131 setting the switch 121 of “2” as the target switch 121 is displayed.

The trainee sees the arrow that is displayed on the monitor device 11 and that faces diagonally upward to the left, and presses the “2” switch 121 that is positioned diagonally to the upper left with reference to the switch 121 that is positioned in the middle of the right side.
The determination unit 132 compares the information indicating the “2” switch 121 from the direction control unit 131 with the information indicating the switch 121 from the operation panel 12 pressed by the trainee. If they match, the time measuring means 133 measures the selected reaction time from the display of the arrow until the target switch 121 ("2" switch 121) is pressed.
Next, the direction control means 131 uses the “2” switch 121 as the target switch 121 as a base point.

  If the switch 121 of “2” is the base point, the adjacent switches 121 are targeted for “1”, “3”, “4” to “6”. The direction control means 131 randomly selects one direction from the directions to the five switches 121. In FIG. 3D, an arrow pointing downward is displayed in which the direction control means 131 sets the “5” switch 121 as the target switch 121.

The trainee looks at the arrow pointing downwards displayed on the monitor device 11 and presses the switch 121 “5” located directly below, with reference to the switch 121 located in the middle of the upper stage.
The determination unit 132 compares the information indicating the “5” switch 121 from the direction control unit 131 with the information indicating the switch 121 from the operation panel 12 pressed by the trainee. If they match, the time measuring means 133 measures the selected reaction time from the display of the arrow until the target switch 121 ("5" switch 121) is pressed.
Next, the direction control means 131 uses the “5” switch 121 as the target switch 121 as a base point.
Thus, the direction control means 131 repeats the exercise | movement (continuous stimulus presentation) by the display of this arrow 15 times, and complete | finishes 1 set.

The computing means 134 computes the time difference for each number of exercises from the measured selected reaction time.
The calculation means 134 can display the calculated time difference for each number of exercises on the monitor device 11. FIG. 4 shows an example of a screen displayed on the monitor device.

As shown in FIG. 4, the display screen of the monitor device 11 has three display frames arranged in rows and two columns in columns.
In the upper left display frame, the required time (selective reaction time) from the display of the arrow to the switch 121 is displayed.
The time difference between the previous required time and the current required time is displayed in the display frame in the upper center. When the time difference is negative, it indicates that the selected reaction time is shorter than the previous time and the reaction is faster.
In the upper right display frame, a number indicating the target switch 121 pressed by the trainee is displayed. In the present embodiment, as shown in FIG. 5, the same numbers as the push buttons “1” to “9” of the telephone are assigned to the nine switches 121.
In the lower left display frame, a number indicating the direction of an arrow for guiding the operation direction is displayed. In the present embodiment, as shown in FIG. 6, “2” is assigned in the upward direction, and up to “9” is assigned every 45 ° in the clockwise direction.
In the lower middle display frame, the target switch 121 indicated by the direction of the arrow is displayed as a correct switch by a number.
The lower right display frame displays whether the switch 121 pressed by the trainee is correct or incorrect. In this embodiment, the correct answer is assigned to “0” and the incorrect answer is assigned to “1”.

  In the example of the display screen illustrated in FIG. 4, the pressed switch 121 is sequentially shifted to “2”, “4”, and “8” as illustrated in FIG. 7. Note that after pressing the “4” switch 121, the arrow is “6” indicating that it is directly below, and the trainee had to press the “7” switch 121, but the “8” switch 121 was pressed. It has been. Next, the base point is “8” pressed by the trainee. This is because the trainee has mistakenly pressed the switch 121 and the correct switch 121 may not be known. In this case, since the base point is lost, if the direction control means 131 uses the correct switch 121 as the base point, there is a possibility that the training cannot be continued once at the wrong stage. Therefore, in the present embodiment, the switch 121 pressed by the trainee is set as the next base point regardless of whether or not it is designated by an arrow.

  Thus, according to the exercise support apparatus 10 according to the present embodiment, as shown in FIG. 3B and FIG. 3D, the base point changes even with arrows in the same direction. The switch 121 changes. Therefore, the exercise support apparatus 10 can change the situation every moment because the arrow indicates a relative direction, so that not only the dynamic visual acuity can be improved, but also the trainee can continuously perform selective reaction tasks. It is possible to improve the ability to react to a change in the situation by presenting to.

  Although the arrow is displayed on the monitor device 11, for example, the target switch 121 is not limited to the adjacent switch 121, and in the state shown in FIG. 121 may be pointed, and a long arrow pointing downward may be pointed to the “9” switch 121. However, doing so requires a total of 16 arrows. The trainee needs to recognize not only the direction of the arrow but also the length of the arrow instantly after the arrow is displayed by increasing the number of arrows from 8 to 16. Therefore, the trainer who has just started training may frequently make mistakes due to misrecognition of the arrow, and may not be trained.

  Since the direction control means 131 of the control device 13 displays an arrow indicating the direction to the target switch 121 adjacent to the switch 121 as the base point, the number of types of arrows can be reduced to eight, so that misunderstandings can be made. While reducing, moderate difficulty can be maintained.

  Since the switches 121 are arranged in a matrix on the pedestal portion 122, the direction of the arrow can be standardized to 8 directions at the maximum.

  Since the selected reaction time is measured from when the time measuring means 133 of the control device 13 displays an arrow until the target switch 121 detects the motion of the trainee, statistical information can be obtained, It is possible to objectively evaluate the degree of improvement of athletic ability and the degree of recovery of athletic ability.

Fourteen male university students who belong to the basketball club of a university in the Kyushu region became trainers, trained using the exercise support device 10, and measured the selected reaction time. The average age of 14 male college students is 19.8 years old, and the average competition experience is 10.8 years.
For comparison, the selected reaction time when using another exercise support device (hereinafter referred to as a comparison device) was measured. In the comparison device, the operation panel 12 is the same, and when the numbers 1 to 9 are randomly displayed on the monitor device, the trainee presses the switch 121 associated with 1 to 9 to display the numbers. The selection reaction time from when the switch is pressed to when the switch 121 is pressed is measured.

For the measurement of the selection reaction time, a set of 15 continuous stimulus presentations (pressing operation of the switch 121) was performed for both the exercise support apparatus 10 and the comparison apparatus shown in FIG.
FIG. 8 is a graph in which the average of the selected reaction times of 14 trainees each time measured by the exercise support device 10 and the comparison device of the example is plotted on a graph from 1 to 15 times.
It can be seen that both devices were unfamiliar with the first time and the selection reaction time was slow.
It can also be seen that the exercise support device 10 has a faster selection reaction time than the comparison device as a whole, and that both devices have a slower reaction time as the number of exercises increases.

  In particular, in the first half of the number of exercises from 1 to 5 times, the difference in the selection reaction time between the exercise support device 10 and the comparison device is greatly open, but the difference in the selection reaction time is reduced from the middle to the end. . This indicates that the exercise support apparatus 10 has a higher degree of fatigue than the comparison apparatus.

  Next, the average of the selected response times of each of the 14 trainees measured by the exercise support device 10 and the comparison device was calculated, and the difference between the selected response times before and after each time was plotted on a graph. . In other words, the difference in reaction time is a value indicating how fast or late the next reaction is relative to the previous selected reaction time. Accordingly, the value is calculated as a negative value when the selected reaction time is faster than the previous time, and as a positive value when the selected reaction time is delayed. The result is shown in FIG.

  As can be seen from FIG. 9, the exercise support apparatus 10 generally shows a positive value, and shows a tendency to become slow while being affected by fatigue without shortening the selection reaction time as the number of exercises increases. . On the other hand, the comparison device does not show a consistent trend, and the value goes back and forth in both positive and negative directions as the number of exercises increases. In other words, it did not show a consistent tendency that the selection reaction time increased or decreased over a continuous number of times.

Next, the number of erroneous presses of the switch 121 was counted.
The timing at which a push error occurs during 15 exercises varies depending on the trainee. Therefore, the number of times of 5 exercises is divided into 3 blocks, with 15 exercises divided into 3 blocks. Totaled.
As can be seen from FIG. 10, in both apparatuses, the number of erroneous presses increases as the number of exercises increases as an overall tendency.

  From FIG. 8 to FIG. 10, since the comparison device assigns a number to the switch and obtains a response by presenting the number, there is no relevance to each exercise, and the trainee determines the position of the switch corresponding to the number. Since it is possible to exercise just by thinking, fatigue occurs when the number of exercises is repeated, but the degree is lighter than that of the exercise support device 10.

In the exercise support device 10, since the next exercise direction is presented by an arrow with the switch 121 pressed by the trainee as a base point, the stimulus is presented continuously, and the own reaction is a trigger for the next reaction. .
Each scene in sports requires a continuous body reaction in an ever-changing environment. Rather than staying in one place and continuing to react in the sport scene, it is considered that the player responds to changes in the surrounding environment while always moving. Therefore, it is considered that the exercise support apparatus 10 in which stimuli are continuously presented and its own reaction is a trigger for the next reaction can present a more realistic selection reaction task that is close to each sport scene. .

  Therefore, the exercise support apparatus 10 not only causes the trainee to exercise, but also continuously presents the selection reaction task to the trainee, so that the trainee accumulates fatigue by reacting to the change in the situation. Therefore, it is estimated that the selection reaction time is delayed at a relatively faster pace than the comparison device.

  The exercise support apparatus 10 according to the present embodiment has been described above, but the present invention is not limited to the above embodiment. In the present embodiment, nine switches 121 are used as detection means for detecting the movement of the trainee. However, instead of the switch 121 pressed by hand, foot switches are arranged in a matrix form in columns and rows, and the soles of the feet are arranged. If the foot switch is pressed at, whole body exercise can be performed. In addition, the projector is used as a display means to display an arrow, and an object corresponding to a switch is displayed. As a detection means, a trainee's hand is photographed with a camera to detect an overlap with the object. But you can do whole body exercise.

  Since the exercise support device of the present invention is suitable for improving athletic ability and restoring exercise function, it can be installed and used in hospitals, exercise facilities, educational facilities, care facilities, etc. Ideal for rehabilitation of the elderly.
