I build the interactive scaffolding that lets designers and generative AI hand intent back and forth — without losing what made it the designer's in the first place.

capturing a designer's intent, decomposing the design into operable parts, structuring the relations between them, and generating outputs that hand the reasoning back to the designer to steer the next move.

Capturing Designer Intent

Two routes — the explicit (direct manipulation, semantic tags) and the implicit (accumulated behaviors, gaze, dwell). Both feed a shared internal representation.

/ decompose

Operable Decomposition

Breaking a design into parts a designer can actually grab — across text, 2D image, 3D shape, and multimodal channels. Semantic and structural decomposition working in tandem.

Structuring Element Relations

A relational graph of design elements that evolves turn by turn — chair → frame → wood → sustainable → bamboo — building a map that the designer can re-enter later.

Generation & Interaction

Closing the loop. Outputs that expose property edges ("is-style-of", "has-property") so designers can reach into the model's reasoning and steer the next iteration.

Unlimited Interior in Design — Be on the alert for the boundary

Be on the alert for the boundary

We coexist through solidarity with time. Unknowingly, we counterattack the paradoxical boundaries drawn. I hope we can erase the boundaries of time and space, pose questions taken for granted, and attempt a counterattack.

EDUCATION · EXPERIENCE
Jiin Choi

Hi, I'm Jiin.
I design at the seam where designers and AI meet.

I'm a Ph.D. & M.S. integrated student at Hanyang University, working with Kyung Hoon Hyun in the Design AI Lab.

My research builds interactive methods that turn the messy, scattered intuitions of designers into navigable cognitive spaces — helping people steer generative AI without losing their own creative voice.
