My Role

My Role

As the Lead Product Designer, I owned the end-to-end UX/UI design of both the VR application and the web platform.


My work in VR focused on UX/UI and interaction design, object texturing, and visual consistency, translating complex clinical workflows into intuitive VR interactions.


For the web platform, I led the UX/UI design, core user flows, and the design of performance reports.


This project was developed in close collaboration with developers, product managers, and clinical consultants.

BACKGROUND

The COVID-19 pandemic exposed gaps in infection prevention and control (IPC) practices across U.S. healthcare.

The COVID-19 pandemic exposed gaps in infection prevention practices (IPC) across U.S. healthcare.

Effective IPC is critical to preventing hospital acquiered infections and protecting both patients and healthcare workers.

IPC Stops the spread of Infection, illness, death and protecting patient and healthcare workers.

Task analysis

Task analysis

Observed and mapped real-world IPC workflows and simulation practices to understand how tasks are performed in clinical settings.

Highlighted the need to balance a linear flow with the option to shift into a sandbox approach.

Usability testing 

Usability testing 

Conducted iterative usability testing including site visits, "think aloud" sessions, and analysis of recorded user interactions with first time VR users.

Revealed hesitation, spatial uncertainty, and missed interaction cues, leading to clearer guidance and simplified navigation.

Intuitive & Clear Use

Intuitive & Clear Use

To support independent use, key actions were consolidated into a single wrist-based entry point, positioned like a watch.


This placement required no visual search, stayed consistently within reach, and followed a real world convention users already understood.


The interface brought together navigation, contextual hints, gesture guidance, and learning modes under one structured menu.


Centralizing access in one predictable location allowed users to focus on the task rather than on operating the system.

Rethinking Movement

Rethinking Movement

Because users could not physically walk between areas, navigation had to be safe, predictable, and time efficient.


Early gesture-based teleportation required precision and led to repeated failed attempts, especially for users with limited VR experience. Navigation was therefore reduced to a single, predictable action: press → open menu → select destination.


Users moved between locations reliably, shortening transitions and preserving workflow continuity.

Users transitioned between locations with minimal hesitation and no need for spatial precision. This reduced transition time, and allowed nurses to continue tasks without disruption.

Immediate, Realtime Feedback

Immediate, Realtime Feedback

Cues highlight contamination risks during the experience.

Post-task review shows where contamination transfer occurred, supporting assessment focused learning.

Connecting Web and vr

Connecting Web and vr

The web portal provides a clear and secure entry into the system. Access is protected through anonymized user profiles aligned with healthcare privacy requirements.


This onboarding stage sets expectations, clarifies goals, and connects the simulation to a broader learning journey.

By structuring the entry point, the product creates continuity between the portal and the simulation without adding complexity to the flow.
