I am a design researcher in the department of industrial design at KAIST, Republic of Korea. I received BSc, MSc, and PhD in industrial design from KAIST.

My research interest is developing new design prototyping tools to support prospective designers. The approach of development lies in integrating scientific knowledge and practical design skills to achieve usable systems. The main objective of my research is to build well-finished prototyping systems to deploy to the public, and derive robust observations and implications from actual usage in the wild. To conduct my previous studies, I was trained as designer-researcher having convergent thinking and skills for visual design, interaction design, system development, and evaluative study.

I have developed several prototyping tools for design scenario (MiniStudio, SketchStudio) and mechanism design (M.Sketch) for my PhD period. Now I am extending my viewpoint to find valuable prototyping system in design practice and education.


Designers’ Tool for Prototyping Ubicomp Space with Interactive Miniature


Recently, it has become common for designers to deal with complex and large-scale ubicomp or IoT spaces. Designers without technical implementation skills have difficulties in prototyping such spaces, especially in the early phases of design. We present miniStudio, a designers’ tool for prototyping ubicomp space with proxemic interactions. It is built on designers’ existing software and modeling materials (Photoshop, Lego, and paper). Interactions can be defined in Photoshop based on five spatial relations: location, distance, motion, orientation, and custom. Projection-based augmented reality was applied to miniatures in order to enable tangible interactions and dynamic representations. Hidden marker stickers and a camera-projector system enable the unobtrusive integration of digital images on the physical miniature. Through the user study with 12 designers and researchers in the ubicomp field, we found that miniStudio supported rapid prototyping of large and complex ideas with multiple connected components. Based on the tool development and the study, we discuss the implications for prototyping ubicomp environments in the early phase of the design.
