Kinetic visual acuity is the second most important factor for athletes after physical and mental.
The training methods for kinetic and dynamic visual acuity are introduced below.
Visual acuity is classified into static visual acuity and dynamic visual acuity.
Static visual acuity is the ability to see a still object.
The visual acuity test using the Landolt ring, which is performed in medical examinations, tests the static visual acuity.
Dynamic and kinetic visual acuity is the ability to see moving objects.
|Dynamic visual acuity||Vertical and horizontal vision|
|Kinetic visual acuity||Depth vision|
There is sports vision as a classification method of visual acuity.
According to the Sports Vision Association, sports vision is classified into the following 8 items.
In particular, in baseball hitting, Kinetic and Dynamic visual acuity are most important.
Sight to see what is stationary. (Measured by general visual acuity test)
Visual acuity for an object that moves in the depth direction.
Visual acuity for an object that moves vertically and horizontally.
Ability to move the line of sight quickly and smoothly.
Ability to identify subtle differences in brightness.
Ability to recognize relative perspectives.
Ability to instantly recognize visual information.
Reflexes related to vision.
Dynamic and Kinetic visual acuity does not improve just by training the eye muscles. It is necessary to train together with the “brain image processing function”.
However, that does not make the training method more complicated.
All you have to do is create a scene that uses Dynamic or Kinetic visual acuity and repeat the training.
This training method does not perform vertical training, but it is effective for horizontal training.
The good thing about this training method is that you don’t need to be prepared. You can train any time you are traveling by train.
This method of training is very effective, but it also requires tedious preparations and a pitcher to go out with. It is also difficult to control conditions such as ball speed, rotation speed, and rotation direction.
If the ball speed is too fast or the rotation speed is too high, the training will have no effect, and if it is too slow, it will have no effect.
It is said that you can train more effectively by using shutter glasses. Shutter glasses are glasses with a flash effect that open and close the shutter at a high speed with a liquid crystal.
“Kinetic Visual Acuity” is iPhone app that trains Kinetic visual acuity.
“Kinetic Visual Acuity” is an iPhone app that trains Kinetic visual acuity, but it is also effective for Dynamic visual acuity.
There are Free and Paid versions of “Kinetic Visual Acuity”.
The difference between the free version and the paid version is the presence or absence of advertisement, the difficulty level, and the presence or absence of test mode.
|Free version||Paid version|
|With ads||No ads|
|Difficulty level＝0～2.5||Difficulty level＝0～4|
|No test mode||Test mode available|
In the paid version “Kinetic Visual Acuity”, you can select “Test mode” or “Training mode”.
Use the selection box (test / train) in the upper left of the startup screen to switch between “test mode” and “training mode”.
You can practice by switching to “Training Mode” even during the test.
In training mode, you can practice the same level again and again.
It’s easy to use, just select a difficulty level and tap the start button.
The moving speed and rotating speed of the hexagonal pillar are determined by the difficulty level.
The trajectory of the hexagonal pillar changes randomly every time, like baseball pitching.
The order of the numbers does not matter. If 2124 is correct, both 1242 and 1224 are correct.
In Test mode, 5 difficulty levels from 0 to 4 are tested, 5 times each, 25 times in total.
The points that can be added are 4 points for ◯, 2 points for △, 0 points for ☓, and the maximum score is 100 points.
It’s easy to use in test mode, just repeat the test “Tap the start button, read the number on the hexagonal pillar and answer” 25 times. Since it is not a time trial, you can interrupt it on the way.
When the test is complete, your score will be recorded.
If you want to cancel the test, you can reset it by tapping the red reset button at the bottom left of the screen.
To check / delete the test score, tap the score button at the bottom right of the screen.
To turn off the sound effect, tap the speaker button at the bottom center of the screen. The sound effect switches on / off each time you tap it.
“Kinetic Visual Acuity HD” is an iPad app of “Kinetic Visual Acuity”.
The usage is basically the same as the iPhone app “Kinetic Visual Acuity”, but the score display is quite easy to understand.
Also, in the iPad version, screen transition from the startup screen to the screen where the hexagonal pillar rotates does not occur.
