I am an assistant professor at Korea Polytechnic University, 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.

Mechanism Perfboard

An Augmented Reality Environment for Linkage Mechanism Design and Fabrication


Prototyping devices with kinetic mechanisms, such as automata and robots, has become common in physical computing projects. However, mechanism design in the early-concept exploration phase is challenging, due to the dynamic and unpredictable characteristics of mechanisms. We present Mechanism Perfboard, an augmented reality environment that supports linkage mechanism design and fabrication. It supports the concretization of ideas by generating the initial desired linkage mechanism from a real world movement. The projection of simulated movement within the environment enables iterative tests and modifications in real scale. Augmented information and accompanying tangible parts help users to fabricate mechanisms. Through a user study with 10 participants, we found that Mechanism Perfboard helped the participant to achieve their desired movement. The augmented environment enabled intuitive modification and fabrication with an understanding of mechanical movement. Based on the tool development and the user study, we discuss implications for mechanism prototyping with augmented reality and computational support.
