As an interdisciplinary team consists of three designers, we are Eunjun Cho, Sangjin Park and Young-Woo Park in Graduate School of Creative Design Engineering at UNIST. During the realization of our project, it required convergence of design and engineering knowledge, and we mingled in the whole design process. Eunjun particularly contributed to product design and form aesthetics, and Sangjin has contributed to technical implementation and design of internal engineering issues regarding our project "stool.D". They are both Master Students in the CDE graduate program. The overall process of this project has been directed by Young-Woo Park who researches about designing future interactive products.
