Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring an accrual of speed and a computer-readable recording medium on which a program for measuring an accrual of speed is recorded. The present invention relates to a feasible speed accrual measuring device and a computer-readable recording medium recording a speed accrual measuring program.

[0002]

2. Description of the Related Art Ability to accurately predict the timing at which a moving object such as a car, an obstacle, or a ball within a field of view, including relative movement, reaches a predetermined point when driving a car or performing various sports. Is required. The ability to predict the arrival time point from the speed of the moving object is called "speed anticipation (ability)". For example, when performing a spike in volleyball, the trajectory and arrival of the ball from the speed and direction of the tossed ball Required for accurate point estimation.

[0003] Speed prediction is also regarded as one of psychological characteristics. That is, a person whose estimated arrival time is earlier than the true arrival time can be determined to have a tendency to react prematurely, while a person whose estimated arrival time is later than the true arrival time can be determined. It can be determined that there is a tendency to show a delayed response. For this reason, speed accrual measurement may be used for aptitude test of a driver.

[0004] As a conventional apparatus for performing such speed accrual measurement, a "speed accrual reaction tester" (manufactured by Takei Kiki Kogyo Co., Ltd.) is known. In this conventional measuring device, a moving lamp serving as a target is linearly moved from the left side to the right side with respect to the subject by a mechanical mechanism using a motor, a gear, a chain belt, and the like. During this movement, the optotype is hidden behind the black shielding plate so that the subject cannot see it. While estimating the position of the optotype moving on the back side of the shielding plate, the subject presses a switch at hand when he / she thinks it has reached the reaction lamp (target position) provided on the front side of the shielding plate. An error time (time lag) is measured in units of 1 msec when the time when the moving lamp actually reaches the reaction lamp is set to 0 for the time when the subject presses the switch. This measurement value is a measurement result of the speed estimation of the subject.

[0005]

However, in the conventional apparatus, the measurement is performed by moving the optotype (moving lamp) by a mechanical mechanism, and has the following problems.

[0006] 1. It is not easy to set the speed of the optotype at various speeds due to the restriction of the mechanical mechanism for moving the moving lamp. Actually, only high speed and low speed are set.

[0007] 2. For the same reason, it is difficult to control the moving ramp to perform various movements. For example, it is very difficult to perform an acceleration motion. In practice, only constant velocity linear motion can be performed.

[0008] 3. The moving lamp moves only in one direction from left to right, and cannot be measured when the moving lamp is moved in another direction, such as moving from right to left, or moving up and down.

4. Since the measuring device is large in size and heavy in weight, it is difficult to install the measuring device. In addition, the production cost is high and there is a problem in terms of popularization.

As described above, the conventional speed estimation measuring device is configured to measure the speed estimation for a moving body that moves linearly at a constant speed in one direction from left to right. It was virtually impossible to measure speed accruals for movement. Therefore, when it is desirable to measure speed prediction in four directions (up, down, left, and right) in a sport suitability test or the like, or to measure speed prediction for acceleration motion, sufficient measurement cannot be performed. Also, in the case of a driving suitability test, it may be desirable to measure both the speed anticipation for the right-to-left movement and the speed anticipation for the left-to-right movement. It was not possible to make detailed and detailed speed accrual measurements.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional speed estimation measuring device.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a speed accrual measuring apparatus according to this embodiment. In this embodiment,
The speed estimation measurement device 1 is configured using a general-purpose personal computer, and includes a computer main body 11, a monitor 12 as a display device, and a keyboard 13 as an input device for a subject.

The computer main body 11 is connected to the monitor 1.
2, a control unit 111 for controlling the movement of the moving object displayed on the screen, a measurement unit 112 for generating a measurement value based on an input from the keyboard 13, and a measurement unit 112
And a data processing unit 113 for processing the measurement value output from the CPU 12 and displaying the measurement result on the monitor 12 in a predetermined format. However, the control unit 111, the measurement unit 112, and the data processing unit 113 are actually realized by a computer program. These can be constructed in the computer main body 11 using a known programming language or operation system.

As the monitor 12, various types of display devices such as a CRT display, an LCD (Liquid Crystal Display), or a PDP (Plasma Display Panel) can be used. Further, a screen may be formed on the screen using a projector or the like, so that the monitor 12 may be used instead.

FIG. 2 shows an example of a display screen 15 displayed on the monitor 12 during speed estimation measurement. Display screen 15
At the start point 20, a circular target 24 moving on the moving route 22, a visible section 26 in which the subject can visually recognize the movement of the target 24, and a visible section 26 provided adjacent to the visible section 26, A masking section 28 in which the movement of the mark 24 is invisible to the subject, and a masking section 2
The arrival line 30 provided at 8 is displayed. For example, the optotype 24 is controlled by the control unit 111 in the computer main body 11 so as to start at the start point 20 on the left side of the screen and to perform a linear motion at a constant velocity toward the reaching line 30 on the right side of the screen. Further, the distance d ₁ in the visible section 26, the ratio of the distance d ₂ from the beginning of the masking sections (i.e. the boundary between the visible section) to reach line 30, for example 1: is set to be 3. In the masking section, the distance d ₂ to the arrival line and the distance d ₃ after the arrival line are set to, for example, 2: 1.

In the measuring device of the present embodiment, the movement of the target is controlled by the computer and is displayed on the screen of the display device, so that the moving direction can be easily set to an arbitrary direction. For example, the optotype can be moved from right to left, or the optotype can be moved from top to bottom or from bottom to top. The start point, the reaching line, the visible section, and the masking section can be displayed at appropriate positions on the screen according to the moving direction of the optotype. That is, when the target is moved in the above-described direction, the screen display on the monitor 12 can be such that the screen display shown in FIG. 2 is rotated by 90 °, 180 °, and 270 °, respectively.

Furthermore, the movement of the target is not limited to a constant velocity linear movement, but may be various movements such as an acceleration linear movement and a sine function movement. The shape of the target is not limited to a circle,
Various shapes are possible. These settings can be easily realized by a computer program in the control unit 111 of the computer main body 11.

As described above, according to the speed accrual measuring apparatus of the present embodiment, the movement of the optotype can be displayed in at least two directions, so that more detailed measurement can be performed by changing the moving direction of the optotype. It is possible. For example, when performing a driving suitability test, it may be desirable to perform an anticipated speed measurement in two horizontal directions, a right-to-left movement and a left-to-right movement. This is because there is often a difference in speed prediction ability in each direction even in the same individual. Also, when conducting a sport suitability test, it is desirable to measure in four directions, up, down, left, and right. Because, in actual sports, it is often necessary to have a speed anticipation ability in the vertical direction, such as catching a fly in baseball or catching a long pass in American football.For example, anticipating speed in one direction from right to left. This is because measuring alone is not enough to judge sports suitability. Also, depending on the individual, even if it is excellent in anticipating speed in the horizontal direction, it may not be excellent in anticipating speed in the vertical direction,
In some cases, one-way measurements alone may not be appropriate to determine an individual's overall speed-sighting ability. The speed anticipation measuring apparatus of the present embodiment is very practical because it can perform more detailed speed anticipation measurement corresponding to such various actual situations.

Further, according to the speed anticipation measuring apparatus of the present embodiment, it is possible to perform speed anticipation measurement when the target is accelerated, so that speed anticipation measurement is performed in a more actual situation. It is possible. For example, in a daily life, a drop of a ball or the like often makes a movement close to an acceleration movement. Also, when driving a car, depressing the accelerator accelerates the car, and depressing the brake decelerates the car. Thus, for example, in a situation where the vehicle is gradually decelerated by applying a brake, speed prediction is closer to constant acceleration prediction than constant speed prediction. It is more effective to conduct a test using a target to be tested. In addition, since the speed prediction for the acceleration motion has a feature that a great difference in individual ability appears, it is also possible to measure a more detailed personal speed prediction capability that cannot be measured by the constant velocity motion.

Hereinafter, the procedure of the accrual speed measurement in this embodiment will be described with reference to the flowchart shown in FIG.

As shown in FIG. 3, when the speed estimation measurement process is started (step S100), step S102 is performed.
, Subject data such as the subject's name, gender, and age are input from the keyboard 13. These subject data are stored, for example, in the data storage unit of the data processing unit 113.

Next, the direction in which the optotype moves is selected.
In the present embodiment, one direction to be measured is randomly selected from four directions from left to right, right to left, top to bottom, and bottom to top on the screen of the monitor 12 (step S).
104). A display screen for measurement as shown in FIG. 2 is displayed on the monitor 12 according to the selected direction. The subject can see, for example, about 32
At a position separated by a distance of cm, the optotype moving and displayed is viewed.

Next, the control section 111 moves the optotype 24 in the direction selected in step S104. The target 24 is
First, it is displayed at the start point 20, and is displayed so as to move in the visible section 26 at a constant speed from there toward the reaching line 30 (step S106). Optotype 24
Makes a uniform linear motion at a visual angular velocity of about 15.625 degrees / second on the screen, for example. In the visible section 26, the subject can observe the movement of the target 24 moving on the screen.

Next, the optotype 24 shifts from the visible section 26 to the masking section 28 (step S108). The target 24 moving in this masking section is displayed on the display screen 1
5 is not displayed. Therefore, the subject estimates the movement of the target 24 moving in the masking section 18.

Thus, the target 24 is placed in the masking section 2
During the movement of No. 8, the test subject
When it is estimated that 4 has reached the reaching line 30 in the masking section, input of a predetermined key of the keyboard 13 (for example, a key previously known to the subject such as a space key) is performed (step S110). When receiving the input from the keyboard 13 by the subject, the measuring unit 112 in the computer main body 11 determines the coordinate position of the optotype 24 (estimated coordinate position by the subject) at that time.
To get from. The measuring unit 112 further includes a control unit 111
Estimated coordinate position (measured value) and arrival line 3 received from
The difference between the coordinate positions is compared with the coordinate position of 0 (true value), and the displacement value represented by the difference is obtained as a measured value (step S112). Here, when the displacement value is negative, it indicates that the estimated coordinate position is on the near side of the reaching line, and when the displacement value is positive, the estimated coordinate position is beyond the reaching line. Indicates that The displacement value thus obtained is sent to the data processing unit 113. The data processing unit 113 stores the displacement value in the measured value storage unit. Thereby, one measurement is completed, and the process proceeds to the next measurement.

By repeating the above measurement,
Measurement accuracy can be increased. In the present embodiment, one of the four directions is randomly selected as the moving direction of the optotype, and the measurement is continuously performed five times in each direction until the measurement is completed 20 times in total (step S114).
In the present embodiment, measurement is performed in four directions from left to right, right to left, top to bottom, and bottom to top. However, a desired number of measurements may be performed in an arbitrary direction such as an oblique direction. It may be.

In order to make the subject fully understand the contents of the measurement, the practice may be performed several times before the actual measurement. For example, in the first practice, the target is moved from left to right without masking, and it is understood that the space key of the keyboard is pressed in the reaching line. Data obtained by this measurement, as data indicating the time difference or error between the time when the subject recognizes that the optotype has arrived at the arrival line and the time when the space key is pressed,
It may be used for background data in speed estimation measurement. Next, the same practice as the first practice is performed with masking. Further, a practice of continuously measuring the four directions of up, down, left, and right may be performed so that the same conditions as those of the actual measurement are experienced.

As described above, when a total of 20 measurements are completed in four directions, a measurement result display process (step S120)
Move to

FIG. 4 is a flowchart showing the details of the measurement result display processing shown in step S 120 in FIG. 3, and is executed by the data processing unit 113 of the computer main body 11. As shown in FIG. 4, first, a determination threshold for performing a performance determination is read from the storage device (step S122). The determination threshold is, for example,
The reaching line 30 after the target 24 enters the masking section
When the time to reach is set to 1, the speed anticipation time is set to 0.
5 or less, 0.5 to 0.75, 0.75 to 1.5, 1.5
It can be a threshold value that is classified into five stages of 1.75 and 1.75 or more. For example, the suitability for driving or the like can be determined based on the classification based on the threshold value.

Next, one direction to be subjected to data processing is selected from the four directions (step S124), and an average value of five measured values (positional deviation values) in this direction is obtained (step S124). S126). By comparing this with the determination threshold (step S128), the grade in this direction is determined.

This data processing is repeated until the processing is completed in all four directions (step S130), and thereafter, a total average displacement value including all the measurement results in the four directions is calculated (step S132). This average positional deviation value is also compared with the read determination threshold value, and the result is determined (steps S134 and S136).

The thus obtained average position deviation value in each direction and the total average position deviation value including all four directions are displayed on the monitor 12 as, for example, a bar graph (step S 138), and the result is also obtained. The judgment result is also displayed at the same time.

These results are automatically stored in a storage device such as a memory device or a flexible disk (step S140), and the measurement results of a large number of subjects can be processed by measuring other subjects. it can.

In the above embodiment, the measurement result is the distance between the estimated position and the arrival line and is expressed as a positional deviation value, but is expressed as a time deviation value by dividing by the moving speed of the target. Is also good. Obtaining the measurement result as the time, that is, the timing shift, has an advantage that it is easier to understand as a human sense than the case where the shift amount is represented by the distance. In addition, in the case of accelerating acceleration accrual measurement,
If the deviation from the position where the vehicle should be stopped is expressed as a distance, even if the deviation is the same in time, the amount of the deviation is measured before or after the position where the vehicle should be stopped. For example, when the moving body accelerates, even if the time shift is the same, the shift before the stop position is short in distance, and the shift after the stop position is long in distance. Become. Therefore,
If the measurement result is obtained as a time shift, it is possible to obtain a result of equally evaluating the shift before and after the stop position regardless of the acceleration or deceleration movement.

In the above embodiment, the control unit 111
Although the display screen 15 is controlled so that the optotype 24 is moved while the masking section 28 is not displayed, the optotype 24 may be controlled to move only the visible section 26. In this case, the speed anticipation measurement measures the time from the start of the optotype 24 from the start point 20 until the subject performs key input by estimation in the measurement unit 112, and measures the time between the start point 20 and the arrival line 30. Only the time lag may be measured in comparison with the true arrival time calculated from the distance between the target and the moving speed of the optotype 24. In this case, the measurement unit 112 does not need to obtain the coordinate position of the target at the time when the subject presses the key from the control unit 111.

Hereinafter, an example of an experiment performed using the speed accrual measuring apparatus of the present embodiment will be described.

(Experimental Example 1) 9 males and females from 16 to 61 years old
For one subject, five measurements were performed on the screen when the target was moved in four directions from bottom to top, top to bottom, right to left, and left to right. The moving speed of the optotype was constant at a visual angle speed of 15.625 degrees / second, and the distance between the screen and the subject was 32 cm.

FIG. 5 shows an average value (however, a time lag value) of the result measured in each direction as described above. As shown in FIG. 5, the one with the largest average time lag value is the case where it is moved from bottom to top (↑), and the one that is moved from top to bottom (↓) is large,
Next, the one moved from right to left (←) is large, and the smallest one is moved from left to right (→). In this way, despite the speed prediction at the same speed and the same distance, the speed prediction for the target moving in the horizontal direction is superior to that for the target moving in the vertical and vertical directions. You can see that it is.
This is considered to be because in everyday life, more objects move in the horizontal direction than in the vertical direction, and the speed prediction in this direction is unconsciously increased.

As described above, with the apparatus according to the present embodiment, it is possible to inspect the difference in the speed anticipation ability for each direction, and it is possible to perform more detailed measurement and evaluation.

(Experimental example 2) 30 male athletes (who played tennis and baseball consistently with junior high school, high school and university)
And 30 male non-athletes (those without intensive sports experience after high school) were measured for constant velocity and constant acceleration. FIG. 6 shows the result.

As can be seen from FIG. 6, regardless of whether the athlete is a sports athlete or a non-athlete athlete, constant acceleration is inferior to uniform acceleration. This seems to be due to the fact that it is more difficult to anticipate the speed in the uniform acceleration motion. It can also be seen that in the same constant speed anticipation or constant acceleration anticipation, the speed athlete is superior to the non-athlete in speed athlete. An athlete is considered to have a high speed anticipation ability through training through training or the like. The results of FIG. 6 show that measurements with the accrual measurement device of the present invention can objectively reveal such entities.

As described above, according to the speed anticipation measuring apparatus of the present invention, not only a moving object moving at a constant speed but also a moving object moving at a constant acceleration can be measured, and measurement in various forms can be performed. . This allows measurements to be made that are more related to various situations in everyday life.

[0048]

As described above, according to the speed anticipation measuring device according to the present invention, the moving direction, moving speed and movement of the target can be set more freely, and the target can be set in various forms such as acceleration movement. Measurement can be performed. Also, it is possible to measure a difference in speed anticipation ability depending on a moving direction of the target. As described above, if the speed anticipation in at least two directions or the speed anticipation with respect to the acceleration motion can be measured, it is possible to measure a more detailed speed anticipation ability that is more suitable for an actual situation in sports, driving a car, and the like. is there. Furthermore, since the speed accrual measurement device according to the present invention can be realized using a general-purpose display device and a computer, anyone can easily perform measurement without being restricted by the installation location.
