User Research for Spotify Car Thing
Four long-term U.S. studies that shaped Spotify's first in-car device, Car Thing
Context
Contracted as Spotify's sole user researcher on the project, I ran month-long diary studies, interviews and surveys to capture how people actually listen and use voice control while driving, then tested behavior in a simulator with eye-tracking.

Research & Discovery

Four month-long field studies, analyzed daily, weekly and monthly with a data scientist using mixed methods.

Reporting & Impact
I delivered insights throughout and a final set of recommendations that design and engineering adopted, informing hardware and software ahead of the 2021 launch.
Mixed-method collaboration
Per the team, the studies led to new features and to hardware flaws being fixed before release.
