Yejin Yun

I am a HCI researcher at Hanyang University in Seoul, Korea, working at the intersection of design, space, and artificial intelligence.

Affiliated with the Design Informatics Lab and the Human-Centered AI Design Institute, I investigate how AI can support and reshape design thinking, creative workflows, and spatial practices.

My work examines Human-AI collaboration in design across multiple scales, from moment-to-moment design actions to broader creative systems and spatial experiences.

Modeling Sequential Design Action as Designer Externalization on an infinte canvas (2026)
Infinite canvas platforms are becoming central to contemporary design practice, enabling designers to externalize cognition through the spatial arrangement of multimodal artifacts.
We report a field study with eight professional designers comparing workflows with and without an AI organizing agent. Through a sequence analysis of 5,838 design actions, we identify three key shifts: AI integration reallocates cognitive effort from spatial management to content curation and relational structuring, without increasing active time. AI's role evolves from a divergent catalyst in early stages to a convergent curator in later phases.

Assemblage City (2026)
Based on the self-built architectural practices of the homeless around Seoul Station, this project reassembles urban resources—homeless communities, urban materials, and underused spaces—to propose a new mode of coexistence within the city.

Seoul Corest (2023)
Seoul Corest began with the question of what it means to transform Seoul Forest into a true forest of Seoul. Inspired by the way dandelion seeds spread lightly and take root across multiple sites, the project reimagines Seoul Forest not as a single centralized park but as a dispersed micro-forest network throughout Seongdong-gu. Focusing on the Seoul Forest commercial district, it explores how rooftops, gaps between red brick buildings, vacant spaces, and other overlooked urban voids can become a new vertical axis for forest expansion, qualitatively extending the forest through the everyday experiences of Seongsu citizens.

Alive (2024)
Alive is an S&S (Space & Social) service that proposes new ways to activate urban dead spaces through an XR environment. The project explores how users can discover, reinterpret, and engage neglected urban spaces by connecting spatial research, media interaction, and 3D visualization.

Morph (2023)
Morph explores how digital lifestyles reshape domestic space for Generation Z. By treating the home as software rather than fixed hardware, it proposes a flexible living platform that adapts to users’ behaviors.

BAN (2024)

The BAN Project reimagines semi-basement housing as a communal spatial system rather than an obsolete defensive structure. By expanding it vertically between ground and underground, the project improves environmental quality and resident interaction, proposing a new model of “common ground” in Songjeong-dong.

Rebeat(2023)

Re:beat is an emergency response drone designed to deliver CPR during cardiac emergencies before paramedics arrive. In situations where bystanders may lack the knowledge, tools, or immediate access to an AED, Re:beat can fly directly to the scene and provide accurate CPR. By connecting with smartphones or wearable devices to detect vital signals and relay them to paramedics, it helps enable faster intervention and improve patient survival rates.

Workerbee flagship store(2021)

WOKERBEE reimagines a honey brand as a spatial platform for bee conservation and sustainable coexistence. Centered on the concept of a “Bees’ Factory,” the project organizes programs, massing, and interior design across three floors to reveal the relationship between bees, food, and people, while offering visitors an immersive experience of honey and ecology.
