An android app that trains your kinetic visual acuity! Kinetic Visual Acuity

3 ways to improve Dynamic and Kinetic visual acuity

◆What is dynamic and kinetic visual acuity?

Dynamic / Kinetic visual acuity is an important factor for athletes.

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 and Kinetic visual acuity differ greatly in the mechanism of the brain that they perceive. Therefore, the training method is also different.

Sports Vision

There is sports vision as a classification method of visual acuity.

In particular, in baseball hitting, Kinetic and Dynamic visual acuity are most important.

According to the Sports Vision Association, sports vision is classified into the following 8 items.

1.Static vision

Sight to see what is stationary. (Measured by general visual acuity test)

2.Kinetic visual acuity:KVA

Visual acuity for an object that moves in the depth direction.

3.Dynamic visual acuity:DVA

Visual acuity for an object that moves vertically and horizontally.

4.Eye movement

Ability to move the line of sight quickly and smoothly.

5.Contrast sensitivity

Ability to identify subtle differences in brightness.

6.Deep vision (sense of distance)

Ability to recognize relative perspectives.

7.Instantaneous eyesight

Ability to instantly recognize visual information.

8.Eye-hand coordination

Reflexes related to vision.

Dynamic Visual Acuity

Visual acuity for an object that moves vertically and horizontally.

Kinetic Visual Acuity

Visual acuity for an object that moves in the depth direction.

Dynamic visual acuity training method

The most popular method of training Dynamic visual acuity is to read the letters written on the outside signs and telephone poles from the train window.

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.

You can do it from the window of the bus, but when you actually try it, it seems that there are fewer suitable objects than when you do it from the window of the train. “From the train window” is recommended.

Kinetic visual acuity training method

A well-known training method for Kinetic visual acuity is to read the numbers or letters written on the thrown ball.

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. )

Android app to train Kinetic visual acuity

The training method of writing numbers and letters on the ball is the strongest, but it is not easy, so we recommend using the app as the next best training method.

There is ‘Kinetic Visual Acuity’ as an android app that trains kinetic visual acuity.

◆ Android app ‘Kinetic Visual Acuity’ free version and paid version

There are a paid version of ‘Kinetic Visual Acuity’ and a free version of ‘Kinetic Visual Acuity Lite’ as android apps that train your kinetic visual acuity.

There is only one difference between the paid version and the free version.

The free version of ’Kinetic Visual Acuity Lite’ requires Fuel when playing outside of level 0. Level 4 play requires Fuel 4, Level 3 requires Fuel 3, Level 2 requires Fuel 2, and Level 1 requires Fuel 1. Fuel can be increased by watching video ads.

The paid version does not require Fuel and therefore has no ad-related display.

◆ How to use the Android app ‘Kinetic Visual Acuity’

In ‘Kinetic Visual Acuity’, you can select test mode or training mode. In test mode, the level is set automatically and the score is recorded. In training mode, you can set the level manually.

【mode switching】

training mode
test mode

You can also switch to “training mode” to train during the test. In this case, you can resume the test by returning to “test mode”.

【training mode : play】

In training mode, you can train as many times as you like at the same level.

It’s easy to use in training mode, just select the difficulty level (lvl0 to lvl4) and tap the play button.

Difficulty level selection

The difficulty level is selected with the buttons lvl0 to lvl4 at the bottom.

Play

When you tap the play button, the hexagonal pillar will pop out from the back of the screen while rotating.
Read the numbers on the sides of the hexagonal pillar.

【About the hexagonal pillar that pops out】

The moving speed, rotation speed, and number of digits of the hexagonal pillar are determined by the difficulty level.

The trajectory drawn by the hexagonal pillar changes randomly each time, like a baseball pitch.

Answer

When you finish entering the read numbers on the keyboard, the judgment is made.

Result: ◯ All digits correct
Result: △ 1 digit incorrect
Result:× 2 or more digits incorrect

【About judgment】

If all digits are correct, it is judged as ◯, if only one digit is incorrect, it is judged as △, and if two or more digits are incorrect, it is judged as ☓.

The order of the numbers does not matter. If 2124 is correct, both 1242 and 1224 are correct.

【test mode : play】

In test mode, 5 difficulty levels from 0 to 4 are tested 4 times each, for a total of 20 times.

【About the score】

The score is 5 points for ◯, 3 points for △, 0 points for ☓, and the maximum score is 100 points.

There are few people who can get 100 points. However, of course, it is not impossible, and there are some who are good at sports and have achieved 100 points many times.

It’s easy to use in test mode, just repeat the test “tap the play button, read the number on the hexagonal pillar that pops out, and answer” 20 times. It is not a time trial, so you can interrupt it in the middle.
