Seijin Cha is a designer shaping interaction between people and digital or physical products from scratch to production in the real world. Seijin currently works as a UX designer in Naver, developing creative works based on user-centered design methodologies.


Seijin has interests in emerging technologies and interfaces, imagining how human beings will react to or interact through them. Recent try was the project WAVE, one of the earliest voice-controlled speakers in South Korea. It was a great chance to explore voice as an interface and to consider complex interaction including physical UI(speaker), graphical UI(smartphone application) and conversational UI altogether.


Seijin participated in experimental design research projects during the master’s course for 2 years. She successfully worked on projects for developing futuristic concepts of interactive products, creating hi/low-fidelity prototypes and studying the behaviors of users with them. Multiple projects were presented or awarded in celebrated conferences in the field of human-computer interaction, such as CHI, UIST and TEI.


As an in-house designer of a tech-oriented company, she is practiced in communicating with various team members, including developers, project managers, QAs, other designers and so on. She tries to clarify given limitations and to figure out a way for higher quality together. She keeps in mind that details matter, believing in importance of trivial but hedonic factors to create more engaging experiences.
