Context
As a Product Design Intern at NCSA, I worked on Voice Vitals, a research platform capturing voice and eye-tracking data originally built as a web portal. My role was twofold: supporting usability testing of the web experience and translating a research-specific camera interface into a mobile app.

Web Usability Testing

At NCSA, I assisted with two rounds of usability testing on the Voice Vitals web portal.
Prepared testing materials: Co-created scripts and identified pain points to probe.
Conducted testing: Supported 45–60 minute contextual inquiry sessions.
Synthesized results: Analyzed feedback and highlighted recurring issues, proposing solutions.
Impact: Our first round of testing increased clarity of the research process by 80% and reduced participant drop-off by 40%.

Mobile Design

I was tasked with translating a complex web-first research portal into a mobile app. The goal was to support participants in completing video-based interviews, demographic surveys, and onboarding flows on smaller screens.

Key challenges:

Hardware-specific constraints on UI: Considering microphone and camera placement and how they impact audio and video quality in relation to research needs.
How can this interface avoid overwhelming troubleshooting?: Designing troubleshooting flows for camera/mic issues
Too much info, not enough space: Supporting long, structured interview questions while keeping the live video feed usable

My process:

Collaborated with the principal investigator to prioritize research requirements.
‍• Ensured clear onboarding for video and audio setup by limiting error prevention pop-ups to one in a prominent spot.
Created new mobile-specific elements in line with the existing design system.
Balanced simplicity with the research complexity by moving questions into a scrollable section and removing the background during video feeds, since multiple border margins reduced usable space.

Outcome

Delivered a mobile-second design that balanced the need for simplicity with the complexity of the research tasks.
