What is miChecker? Summary of web accessibility evaluation tool functions provided by the Ministry of Internal Affairs and Communications

Have you ever wanted to check whether your website is easy to operate for any user, such as the elderly or people with color blindness ?
A useful tool for such people is *”miChecker”* provided free of charge by the Ministry of Internal Affairs and Communications.

This time, we will introduce the basic usage of the web accessibility evaluation tool “miChecker”. “miChecker” is a tool that allows you to easily check whether a website complies with the JIS standard “JIS X 8341-3:2016” for web content
that is easy to use for the elderly and people with disabilities . You can use it for free, so please take this opportunity to check out our website .

What is “miChecker”?

“miChecker” is a web accessibility evaluation tool provided by the Ministry of Internal Affairs and Communications to check whether the websites of national and local governments are easy to use for everyone .

For the evaluation criteria , we have adopted the industrial standard “JIS X 8341-3:2016”, which stipulates web content that considers the elderly and people with disabilities . “JIS X 8341-3: 2016” is based on the “Web Content Accessibility Guidelines (WCAG) 2.0” guidelines for web accessibility announced by W3C, which defines international standards
for web-related technologies. You will be able to know the correct evaluation even if you look at it.

Precautions when using miChecker

miChecker is only available for Windows and does not support other OS such as i OS . Also, since the usage environment is set as follows, let’s check if it can be used on your own computer before installing.

Functions of “miChecker”

“miChecker” accesses the homepage and displays the review screen on the right window. From the window at the bottom of the screen, you can check two evaluation reports, “Summary Report” and “Detailed Report”.

“miChecker” has the following two functions.

Let's take a closer look at each function.

1. Voice usability visualization

You can check whether it is designed to read aloud correctly when introducing the text-to-speech function for users who have difficulty reading the homepage .

As shown in the image above, a color-coded screen will be displayed according to the time it takes to read. For example, on the tabs at the top of the homepage , you can see that the more you move to the right, the more time it takes to finish reading.

With “miChecker”, not only text content but also logos and images are converted to text and evaluated for each element from the viewpoint of “operability” and “understandability”. From the overview report, you can check if there are any improvements to be made to your home page
as shown above . You can check the corrections from the detailed report, so let’s figure out which elements are stumbling.

2. Low vision simulation

People with color blindness, who see certain colors in a different way than normal, would have a hard time imagining what they would look like unless they were the person themselves. With “miChecker”, you can set your visual acuity, type of color blindness, and age as shown below, and simulate how the website will look.

For example, even if you are in your 40s and have a visual acuity of 1.0, you will see the following differences in the way you see if you have protanopia (red blindness).
In the window on the right of the image, in the case of color blindness, the orange button that says ” subscribe to RSS ” and the green button that says “friend on LINE” look the same. You will see that it has a bright yellow-green color.

From the detailed report, you can see specifically where you are using difficult-to-see color combinations.
The severity of the visibility is also displayed, so let’s refer to it when making corrections.

summary

“miChecker” can mainly use the following two functions.


You can check the operation method of each function from the manual displayed after installing miChecker, so please refer to it as well.

User accessibility can be improved by varying color combinations and text contrast. In particular, the simulation function that allows you to set the type of visual acuity, color blindness, and age and check how the website looks will be helpful in web design.
