Project Overview
Project Overview
Virufy was developing an AI model to detect respiratory diseases through cough analysis, but lacked a product experience that demonstrated how the technology could work in practice.

I designed and tested an end-to-end mobile research experience for collecting cough, breathing, and health data.
The prototype was showcased at KIMES 2025 and contributed to research partnerships with Seoul National University, Dongguk University, and UNIST’s MAI-Lab.

Product Experience
Guiding participants through every step of respiratory data collection.
I brought cough recording, breathing samples, and health assessment into one guided mobile flow designed to reduce participant error and improve data consistency.

Record Cough
Goal
Capture three usable cough samples from each participant.
Capture three usable cough samples from each participant.
Design Response
First-time participants may be unsure how to position the phone, when to cough, or whether they recorded correctly. I used visual guidance, step-by-step progress, and playback before saving so participants could follow the recording process and review each sample before moving on.

Record Breath
Record Breath
Goal
Collect consistent 30-second breathing samples from each participant.
Collect consistent 30-second breathing samples from each participant.
Design Response
Breathing recordings require participants to maintain the right position and breathing pattern for 30 seconds. I used visual guidance and a timed recording flow to show exactly how to position the phone, how to breathe, and when the recording was complete.

Health Assessment
Health Assessment
Goal
Collect relevant demographic and health data to provide context for each participant’s audio samples.
Collect relevant demographic and health data to provide context for each participant’s audio samples.
Design Response
Based on the study requirements, I identified and organized the demographic and health variables needed for analysis, then grouped them into Basic Information and Current Health to make a complex questionnaire easier to navigate.

Goal
Clearly confirm that participants’ health and audio data were successfully submitted.
Clearly confirm that participants’ health and audio data were successfully submitted.
Design Response
After sharing personal health data, participants need clarity on what happens next. I provided a unique participation ID, submission confirmation, and a brief explanation of how their data would be used for research.

Final thoughts
Final thoughts
This project taught me to design beyond the interface by considering how participants behave while meeting the needs of the research.
Every decision, from recording guidance to questionnaire structure, was shaped by one question: How can we make participation easier without compromising the data researchers need?
