Background
Designing a Dual-Use Laser Therapy System for Clinical and At-Home Users
We were simultaneously designing the UX/UI and working with a team of Engineers and Industrial Designers to develop the physical product—a cold laser therapy device intended for both at-home and clinical use. I conducted user research and interviews to inform both the usability of the physical device based on intended use and user behaviors as well as the graphic user interface on the device itself. The system also includes a companion app, which allows users to control and manage laser presets and treatment protocols tailored for different conditions.

Problem
Objective findings for dual users groups
To ensure a seamless, intuitive experience across both the device and the app, we needed a clear understanding of user expectations and workflows. Through interviews and research, we identified two distinct user groups with unique needs: clinical users who operate the device in fast-paced, shared environments, and individual users who use it at home in more controlled, personal settings.
This distinction required us to design two tailored app experiences—one optimized for efficiency and multi-user access in a busy clinic and another streamlined for personal use at home. Without direct user insights, there was a risk of designing a one-size-fits-all solution that wouldn’t fully meet the needs of either group.

Research & Ideation
User-Driven Refinements
We tested early prototypes to understand how each group navigated the device and app. Clinics required quick access and seamless handoff, while at-home users needed clear guidance. Real feedback challenged assumptions, allowing us to refine both interfaces for intuitive, user-specific experiences.

Results & Takeaways
Cross-Interface Integration
Through user interaction and feedback, we designed intuitive interfaces for both the laser therapy device and its companion app. A directional keypad streamlined navigation, addressing concerns about prolonged use, safety, and visibility on hard-to-reach areas. Iterative prototyping and testing ensured a user-friendly experience.
For the app, workshops and real-world feedback shaped key features, including pre-treatment guidance, real-time assistance, and progress tracking. Visual design elements created a seamless connection between the device and app, using familiar color paradigms to enhance readability and user confidence.
