Take a moment to think about your day. Did you watch a video with captions because you were somewhere too noisy — or too quiet? Did you crank up your screen brightness because you couldn’t see it in the sun? Did you navigate your phone with just your thumb while carrying something in your other hand? Did you switch on dark mode because your eyes were tired? Congratulations. You are already an accessibility user. ...
May is a special month in Korea — packed with occasions to reach out to the people we love. Children’s Day (May 5), Parents’ Day (May 8), Teachers’ Day (May 15), Couples’ Day (May 21)… it’s no accident the whole month is called Family Month. Flower shops overflow with carnations, and KakaoTalk fills up with heartfelt digital cards. Sending a digital greeting card has become second nature. But I want to ask a simple question. ...
Prologue I’d prepared for this talk as a natural extension of the work I do every day, so I didn’t expect to be particularly nervous. But when I saw the list of other presenters ahead of time, I found myself wanting to do justice to the occasion — to make sure my talk held its own alongside theirs. Event poster — AI Accessibility Seminar: Accessibility for All. Date: Thursday, April 23, 2026, 10:00 AM – 12:20 PM. Venue: NIA Seoul Office, Basement Conference Room. Hosted by: Digital Accessibility Standardization Forum. Organized by: Universal Design Society. Event poster So I put together clean slides, wrote out a full script, ran through a few rehearsals — and headed to Seoul. The trip from Daegu isn’t exactly short, but I was in good spirits. There’s something about being needed, about being put to use, that makes you feel alive. ...
This post is part of an ongoing effort to monitor public websites as a web accessibility professional. It is written with the goal of improving information accessibility and advancing technology — not as a political statement. I only recently found out the Cheong Wa Dae website had been redesigned. Life gets busy, and I was a bit late to the news — but as soon as I heard, I was curious enough to check it out. ...
Every year, April 20 is Disability Day in Korea. I’ve been working on web accessibility at a university since 2010, but honestly, I never made a point of marking this day. I’d catch news about events held under the banner of Disability Day, but my own work felt like something that lived inside a monitor — far removed from those in-person gatherings. Then this year, on that very day, I received Korea’s Minister of Education Commendation. ...
Introduction “How hard can a signup form be?” If that thought has ever crossed your mind… you’ve probably never tested it for accessibility. Forms are the most important interface for user input on the web. Login, checkout, search, surveys — virtually every core web function goes through a form. Yet for countless people, these forms are a complete barrier. Screen reader users can’t tell what an input field is asking for Keyboard-only users get stuck in front of a date picker People with cognitive disabilities see an error message but have no idea how to fix it A web form with multiple input fields — easy to get lost in, just like people navigating a maze. Photo: Susan Q Yin / Unsplash In this post, we’ll go through form accessibility from top to bottom, based on WCAG 2.2. No dry theory — just practical code you can use right away, paired with a demo page I built for this post. ...
Imagine a webpage with five images. Four of them have no alt text. When a blind user visits this page using a screen reader, those images are announced simply as “image” — or worse, as a raw filename. No meaning. No context. This isn’t a hypothetical. It’s the reality measured by South Korea’s 2025 Web Information Accessibility Survey, published on March 27, 2026. A user sitting in front of a laptop — without alt text, all image information is completely blocked Photo: Ardalan Hamedani / Unsplash What Changed This Year South Korea’s 2025 survey adopted a new standard. The guidelines were updated from KWCAG 2.1 (24 criteria) to KWCAG 2.2 (32 criteria), with 9 new items added. ...
Introduction “We used red and green to distinguish them, so it should be fine.” It’s a thought that comes up naturally during development. But more people than you’d expect have difficulty telling those two colors apart. Statistics based on Northern European ancestry suggest that roughly 1 in 12 men and 1 in 200 women have red-green color vision deficiency. The exact ratio varies by region and genetic background, but the fact remains: there are always users who struggle to distinguish red from green. ...
This essay records what I have wrestled with on the ground about web accessibility, public web services, and the responsibilities of developers. Between law and technology, standards and reality, I try to answer the question: “Are we truly building for everyone?” Is today’s Seollal(Korean Lunar New Year) really providing equal information to everyone? Produced by: Nano Banana Ahead of the Seollal(Korean Lunar New Year) holiday, I browse the web to find helpful information. Seollal(Korean Lunar New Year) is a uniquely Korean holiday. As I visit site after site, the first thing I often encounter is an auto-rotating banner or card news. Around Seollal, these banners include important government notices like emergency information. ...
Introduction Have you ever tried using the internet without a mouse? Most people take their mouse for granted. But there are many people who can’t use one. People with physical disabilities who can’t operate a mouse People with repetitive strain injuries like carpal tunnel syndrome People with temporary arm injuries Power users who simply find keyboards more efficient For these users, the question “Can I use this site with just a keyboard?” is crucial. ...
