Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting 11-13% of women of reproductive age, characterized by a wide range of symptoms (e.g., menstrual irregularity, acne, and obesity) that varies among individuals. While self-tracking tools help PCOS patients to monitor their symptoms and find personalized treatment, they often focus on regular periods of healthy women with inadequate support for the 1) personalization and 2) long-term holistic tracking necessary for managing complex chronic conditions like PCOS. To bridge this gap, the first author (who has PCOS) conducted an autoethnographic study of holistic self-tracking over a period of ten months in an effort to manage her condition. Our results highlight the challenges of personalized, holistic, long-term tracking in medical, socio-cultural, temporal, technical, and spatial contexts. Based on these insights, we provide design implications for tracking tools that are more inclusive and sustainable.

Qualitative UX research practitioners analyze data to comprehend users' needs and synthesize implications for future design. Working with multiple stakeholders is inevitable in modern product development, and in industry, coordination and collaboration add pressures to already laborious qualitative data analysis tasks. In our work, we investigate how multi-stakeholder collaboration specifically affects industry qualitative data analysis practices. We investigate the challenges practitioners face, limitations of current tools, and opportunities for computer-supported cooperative work.

ToonNote is a novel technique for representing computational notebooks in the form of interactive data comics. ToonNote provides a high-level, curated narrative of the dataset in Comic View. Readers can focus on data storytelling, and not be hindered by code, unnecessary outputs, or markdown and can switch back to the Notebook View when needed.

Physical computing is a complex activity that consists of different but tightly coupled tasks: programming and assembling hardware for circuits. We propose a general-purpose prototyping tool based on conversation. HeyTeddy guides users during hardware assembly by providing additional information on requests or by interactively presenting the assembly steps to build a circuit.

In this research, we explored the effects of the internal structure on the texture of chocolate by designing, building, and testing chocolates with different internal structures and internal chocolate percentage. Multiple layers of patterned chocolate were stacked as a fabrication method. Each layer was fabricated using a silicone mold that was made using a 3D printed model. We created seven types of chocolate variations through this system.

Treating dyslexia during childhood is very important. In Korea, this is not the case since the condition is not well understood. Also, there is a limited number of medical centers that offer treatment for it. We propose an education app for dyslexic children ages 5-10 in Korea that can help these children through active learning. By teaching the children Korean phonics using 'nonwords' in a fun and engaging way, they can be treated at home instead of visiting the medical centers.

Hospitalized children are often asked to regularly walk in the hallway to stay active. However, the hallway is usually dull and empty. We created wallpapers and floor footprint stickers that use nudge design to be fun and engaging. Footprint stickers promote walking and leg stretches while the wallpaper contains stories that can add fun moments. Children are guided through stretching activities indicated on the wall.
