Our stories shine brighter when we're together — let's meet the amazing Dot Team!
Today, we have some special guests joining us for an in-house interview.
It’s a funny coincidence, but both of them showed up wearing matching gray tops and bottoms — and they didn’t even plan it! These two amazing individuals play an essential role at Dot. Please welcome our visually impaired colleagues, Assistant Manager Misook Ko and Staff Member Hyunjong Han.
Q1. Let’s start with an introduction from both of you!
Hyunjong sitting on a deep green sofa, introducing himself
(Hyunjong): "Hmm, I’m not sure how to introduce myself, but here goes! I’m Hyunjong Han, and I’m in charge of software testing at Dot. I’m in my mid-30s, living in Seoul, and my MBTI is ENTP! (laughs)"
Misook sitting on a deep green sofa, introducing herself
(Misook): "Hi, I’m Misook, and I’m in charge of branding at Dot. I also handle PR and customer support (CS) tasks. I’ve done a lot of interviews before, but this is my first time doing an in-house interview, so I’m a little nervous! Honestly, this is already my third time doing something like this, but it still feels a bit cringy. (laughs)"
Q2_ I'm curious about what you do. Can you share a bit more about your work?
(Hyunjong): "At Dot, I’m responsible for testing development, devices, and software services. But instead of just focusing on technical features or functions, my main role is to ensure that our products and services are accessible and easy to use for visually impaired users. Since our company creates and sells products for people with visual impairments, it’s essential to check how user-friendly they are from an accessibility perspective.
If I notice any inconveniences or flaws during use, I provide feedback to the development team — though, honestly, it feels like I’m constantly pushing them to make changes (laughs). But it’s all to make sure the final product is as user-friendly as possible."
(Misook): "I’m mainly in charge of PR and customer support (CS) at Dot. While Hyunjong focuses on technical aspects, I focus more on usability. For example, I conduct usability tests not only with internal staff but also with external users to see how easy our products are to use.
On the CS side, I handle customer inquiries. This includes helping users understand how to use our products, like the Dot Watch, and assisting with after-sales (AS) service requests. I’m also involved in braille verification and related tasks.
On the PR side, I review the content of newsletters to ensure that it’s accessible and easy for visually impaired users to read. I also check if the text descriptions for images are clear and properly structured. Additionally, I review and approve internal video shoots and interview requests to make sure everything aligns with our messaging and accessibility standards."

Q3. What does "braille" mean to you both?
(Misook): "For me, braille was just something I had to do. It’s kind of like how sighted people have to go to school and study — it was something I had no choice but to learn. I lost my sight later in life, so if I wanted to do anything, I had to learn braille. I also wanted to go to college, so learning braille was a must.
Back then, there were screen reader programs, but they weren’t as advanced as they are now. So, for me, braille was something I had to force myself to learn, whether I liked it or not."(Hyunjong): "I lost my sight when I was 28 or 29, so I knew I had to learn braille. It was difficult at first, but honestly, life as a visually impaired person is tough without braille. For me, braille is absolutely essential. Thanks to braille, I can access information on subways and elevators, which would be much harder without it."
Q4. What’s your most memorable moment while working at Dot?
(Hyunjong):"About two months after I joined the company, we had a welcome dinner! It wasn’t an official company event — just a casual get-together with team members. It was a chance for all of us to connect and get to know each other outside of work. Oh, and we ate grilled pork belly! Gosh, the pork is always my go-to food! (laughs)"
(Misook): "The most memorable moment for me was last summer. I was walking with Sae Byeol and Manager Choi, and we talked about expressing the words ‘iced’ and ‘hot’. At that moment, Sae Byeol and I started doing a playful sign language version of the song ‘Hot, It’s Hot, It’s Hot’, and our manager got so embarrassed!
Looking back now, I think I’m a little embarrassed, too. (laughs)"
Misook smiling as she expresses 'Hot' in sign language.
We also had a program called ‘우리들의 점수’, where we learned braille and sign language together. It was such a fun time! We even invited staff to join in, and it became a great opportunity for everyone to connect and understand each other better. I hope we can have more moments like that in the future. Let me share a video from Our Score with you!

(Hyunjong): "Exactly! I hope we can have more programs like this at Dot that help raise awareness and understanding of disabilities."
Q5. Do you have any special memories with the people you've worked with at Dot?
(Misook): "This year, I was in charge of organizing the Disability Awareness Day event at the company. We even had prizes — the 1st place winner got $100! The game worked like this: participants drew a card with a number and had to find the matching braille number card. If they succeeded, they moved on to the next round, where they had to guess the sign language. If there was a tie, we settled it with a braille writing challenge to determine 1st, 2nd, and 3rd place winners, and we gave out prizes. The participants had a blast! Though I must admit, there was a bit of cheating in the middle, but that just made it more fun. (laughs)"
(Hyunjong): "I think it would be cool to have a program where employees can experience what it’s like to be visually impaired. For example, starting on the first floor and trying to find your way to your desk while blindfolded. Of course, we’d have to ensure.
Q6. What are your dreams or goals that you want to achieve with Dot in the future?
(Hyunjong): "To be honest, I never expected to work in the field of assistive devices for visually impaired people. I originally studied web development, so testing devices and software was completely new for me. But after joining Dot, I received so much support and guidance from my team members that I started to learn more.
Now, I think a lot about how my work can actually make the lives of visually impaired people more convenient. For example, devices like the Dot Pad can make a real difference in people's daily lives. The thought that our devices could be used by people at work or in their everyday routines makes me feel really proud. My goal is to keep improving our devices little by little so that more people can benefit from them and have an easier, more independent life."
(Misook): "Honestly, I’ve never been someone with big, grand dreams. I just wanted to live a normal, ordinary life. I lost my sight when I was in my first year of high school, and from that point on, I told myself, 'I just want to live a normal life.' That’s all I wanted.
But after joining Dot, my mindset changed. I started thinking, 'If there’s a product that’s easy for me, as a visually impaired person, to use, then wouldn’t it be just as easy for other visually impaired people too?' That realization shifted my perspective.
Now, my goal is to help create products that are more user-friendly for visually impaired people. I believe that even small changes can make a big difference in people's lives. (laughs)"
Q7. If you could give one piece of advice to juniors who see you as a mentor, what would it be?
(Hyunjong): "Ask questions! Please. No matter where you are — at work, in school, or in relationships — if there’s something you don’t fully understand, don’t just let it slide. Ask right away.
If you keep going in the wrong direction because you didn’t ask for clarification, it can be really hard to backtrack later. There’s always someone who’s walked that path before you, so it’s smarter to ask them directly. It may feel like you’re being annoying or bothersome, but in reality, it saves you time and prevents mistakes. So, whatever you’re doing, I recommend you ask questions as soon as they come to mind."
(Misook): "I have two pieces of advice.
The first is, ‘Be open-minded.’ Whether it’s advice from your boss, your juniors, or anyone else, you should have an open heart and be ready to listen. People say you can even learn from children, right? It’s true. Your boss isn’t always right, and neither are your juniors. What’s important is to listen and consider different perspectives.
The second is, ‘Take on challenges.’ Even if something seems impossible at first, you won’t know until you try. Sometimes, it feels like you’re standing in a vast desert, but if you keep going, you’ll eventually find an oasis. Don’t decide something is 'impossible' before you’ve even tried. Be open and be bold.If I could leave just two messages for you, they would be:
‘Be open-minded’ and ‘Take on challenges.’ I hope you’ll always remember them."
