Research

I explored the challenges of chopstick use for people with Parkinson’s disease who experience hand tremors, reduced grip strength, and limited fine motor control. I conducted both primary research, including interviews and anthropometric measurements, and secondary research using academic journal articles. Based on these findings, I created a persona that presents the user’s profile, goals, pain points, and preferences, as well as an empathy map to better understand the user’s needs and wants in dining contexts.

I also conducted a task analysis of the user to identify pain points and usability objectives. In addition, as a designer, I mimicked the user’s restricted finger movements to better understand the challenges that people with Parkinson’s disease may face when using chopsticks.

Furthermore, I conducted product analyses of conventional stainless-steel chopsticks commonly used in Korea, as well as existing assistive and ergonomic chopsticks designed to support people with limited dexterity. I then developed design specifications based on the findings from my research.

Through this research, I learned how human-centered design can address users’ needs. I also realized that assistive products are connected not only to physical aspects but also to cognitive aspects such as independence and social comfort.
