Context
The Challenge: Envisioning seamless driver journeys through UWB-powered personalization.
In SI 594: Automotive User Experience, in collaboration with GM, I explored how Ultra Wideband (UWB) technology could create more seamless and personalized vehicle experiences, both inside and outside the car, through user-centered research and scenario-based design.
Target Audience
Buick attracts the modern, young professional who wants an entry-level luxury vehicle.
Emphasize Quiet Luxury
Deliver concise, high-relevance content summaries that fit within clinical time constraints.
Health & Wellness
Health and wellness is central to the brand, emphasizing calm, comfort, and simple tech that reduces stress.
Promote Wellness-Driven Features
Surface clear indicators of trustworthiness like journal type, study size, and peer-review status.
In-Car Commerce
GM's previous Marketplace failed due to too many steps and a cumbersome experience.
Simplify Transaction Flows
Drivers want fast, simple, and context-aware transactions.
Convenience is Key
Drivers expect things to be effortless. They want actions to be timely, relevant, and tailored to their needs.
Deliver Contextual Automation
Offer AI search features with adjustable levels of automation to accommodate different comfort levels.

We decided on a UWB-powered experience that streamlines in-car payments and introduces health and wellness-aware features.
After consulting with the GM design team, we focused on features tailored to the young professional driver. We chose to prioritize an in-car payments system that streamlines transactions at gas stations, drive-thrus, and curbside pickup, supporting a busy, on-the-go lifestyle.
To reflect Buick’s focus on health and wellness, we also introduced a feature called Purification Profiles. This system provides personalized air quality settings based on each driver’s individual preferences and health needs.
Initial explorations
With this direction, I started creating low-fidelity sketches to visualize key interactions and layout ideas, focusing on the driver display and UWB payments feature.
