Celebrating Teacher’s Day with Professor

We are delighted to share that Professor Kyung Hoon Hyun, an alumnus of our lab, has been elected as a 2026 member of the Young Korean Academy of Science and Technology (YKAST)! We sincerely congratulate him on this remarkable accomplishment!

Dr. Kyung Hoon Hyun has been selected as a member of the Young Korean Academy of Science and Technology (YKAST)!

Our PhD alumna, Gibbeum Lee has been selected as a KAIST Jang Young-Sil Fellow. This fellowship recognizes outstanding young researchers and supports their postdoctoral work at KAIST.

We are glad that Gibbeum will continue her research in our lab as a postdoc, carrying out the project “A Perception Graph Framework for Dynamic User Experience Analysis in Built and Virtual Environments”.

We are delighted to share that Dr. Tse-Wei Hsu, an alumnus of our lab and former co-advised student of Prof. Ji-Hyun Lee, has recently transitioned from his faculty position at Southern Taiwan University of Science and Technology (STUST) to join National Yunlin University of Science and Technology (NYUST) as a faculty member!

Congratulations to Dr. Tse-Wei Hsu on his new faculty appointment at NYUST!

This year marks the 20th anniversary of the Culture Technology (CT) Department at KAIST — a milestone that brought together not only current students and faculty, but also our beloved alumni from around the world.

Some of our seniors returned to campus all the way from overseas just to celebrate this special occasion with us. It was more than just a gathering. It felt like a real homecoming, filled with laughter, warm memories, and inspiring stories. Seeing everyone back together reminded us of how far we’ve come and how deeply connected we are through CT.

“It was a really amazing experience yesterday. Time flies and it's hard to believe now it is 2025.” —— Professor

From research projects and thesis presentations to late-night studio collaborations, it feels like just yesterday we were all sitting in the same classrooms. Now, two decades later, we’re proud to see how our department has grown — not just in size, but in global impact and creative ambition.

Celebrating 20 Years of Culture Technology: A Heartfelt Reunion

This Teachers’ Day, we surprised our advisor, Professor Ji-Hyun Lee, with a small celebration.

As we handed the cake to her, she smiled and shared:

Every year, I still feel like this day is for my teachers… I didn’t realize I’ve become a teacher myself.

This moment felt even more special as Professor Lee recently heard that some of her former students plan to return to visit her for the 20th anniversary of the Culture Technology department (CTescape).

Thank you, Professor Lee, for the countless ways you guide, support, and inspire us. We’re proud to be part of your story.

Happy Teachers’ Day!

Celebrating Teacher’s Day with Professor

We were pleased to welcome Prof. Andrew Li, former professor at Kyoto Institute of Technology, to our lab as a guest speaker in preparation for our future Shape Grammar course.

His visit offered valuable discussions that will help us build a strong foundation for the class in the near future.

We look forward to offering the Shape Grammar course soon and are excited about what’s to come!

#IBDlab #KAIST

Prof. Andrew Li for Shape Grammar Class Preparation

Our former lab member, Dr. Taeha Yi, has been appointed as a professor in the Department of Media and Communication at Gachon University, starting in March 2025. After working at Samsung, Dr. Lee now continues our lab’s tradition of academic excellence.

We are incredibly proud of this achievement and look forward to seeing his impact in the field. Congratulations, Professor Lee!

For more details, visit Gachon University.

Building a GIS Framework for Real-Space Metaverse: AI-Based Prediction of Spatial Information Use and Efficient Maintenance

실공간 기반 메타버스의 GIS 구축방안: AI 기반의 공간정보 사용 예측 및 효율적 유지보수 방법 개발 연구

Project Introduction

This project addresses the challenge of managing spatial information in Digital Twin (DT)–based metaverse environments. By integrating real-world spatial information with user behavioral data collected in virtual environments, we developed a framework for efficient spatial management and personalized user experiences.

Using a large-scale Minecraft testbed of Daejeon city, we collected more than 750,000 user logs and survey responses from 232 participants. Based on this dataset, we created methods for graph-based spatial importance analysis and applied Graph Neural Networks (GNNs) to detect communities and predict priority areas for spatial information maintenance.

Placemaking based on Augmented Proximity

Like the term Urban Assemblage, cities include creating local contexts through diverse networks and relationships created by human and non-human elements.The emergence of Urban Assemblage in early 2010 is changing the flow of urban research, emphasizing the importance of network understanding in cities. Therefore, this study aims to analyze the regional structure of Daejeon from the perspective of ‘visiting’ and ‘education’ through the understanding of residents in different contexts and environments. In addition, the local value is improved by solving the limitations of physical proximity through metaverse-based virtual proximity. Augmented proximity, a concept that unifies physical and virtual proximity, is important here. With the continuing increase in online communications, virtual proximity as well as physical proximity has become a common way to connect individuals. Virtual proximity refers to the psychological closeness felt by people based on their participation in a virtual space. Hence, augmenting physical proximity with virtual types is believed to enhance connectivity within social networks, and applications that consider both types have the capability to provide new forms of interaction. In the end, we plan to provide a metaverse-based solution that can actually help users along with SKT data analysis by applying the augmented proximity concept to cities.

Understanding service connectivity based on digital serendipity: An actor-network approach

The term smart city is an emerging urban concept that provides optimal public services in a city as a hybrid combination of people, technology, and place. However, previous research does not consider various factors and either depends on technology development or studies of human and non-human factors separately.
