Former SK Telecom / T map UX Design Manager Bachelor degree from Mathematics major in Sun-Yet San University, PhD from Interaction Design major in Kookmin Univ. After PhD, I have been working in SK Telecom, being in charge of Interaction Design in the project “T map for Car” and some other projects. My research interest “Interaction Design Language” has been successfully applied in the actual project, allowing us to make better interaction design than google map at that moment. It also demonstrated the value and impact of deep level design thinking. I’m currently working as an assistant professor in Kookmin Univ., keep developing “Interaction Design Language” and its applications. “The path to the future lies in the shadow of the past.” As a interaction designer coming from a mathematical background, I’m fascinated by the exploration of the essence of interaction design. After getting master’s degree in Kookmin Univ., I’ve been working as interaction designer in design agency and smartphone manufacture, while at the same time thinking about how to design interactions more efficiently. As the movie “Arrival” says, the language you speak will affect the way you see everything. The research and practice of Interaction Design Language is an attempt to explore the essence of interaction design.
