CASE STUDY

UX / UI Design // Insulin Pump Remote Control App

PROCESS

Immersion & User Research - The foundation of this project was deep immersion into the experiences of patients living with Parkinson’s Disease. I conducted extensive research to understand the progression of the disease, common motor and cognitive limitations, and how these factors impact interaction with digital products. Special consideration was given to the older age demographic, influencing decisions around readability, interaction patterns, and visual clarity.

Workflow Alignment & Concept Refinement - Using the client’s recommended workflow as a starting point (see below), I translated complex medical processes into simplified, user-centered flows. Multiple concepts were explored and refined to ensure each step felt logical, manageable, and supportive rather than overwhelming. The workflows were intentionally designed to guide users through tasks with minimal decision-making and reduced cognitive load.

Iteration & Feedback - Throughout the design process, I actively sought feedback to validate usability decisions and refine interactions. This iterative approach helped ensure the final experience met both the functional requirements of the insulin pump and the accessibility needs of its users, reinforcing the goal of delivering a premium, high-quality product.

CHALLENGE

This consultant project focused on designing a remote control mobile application for an insulin pump, specifically tailored for patients living with Parkinson’s Disease. The objective was to create a user-friendly, premium-quality interface for individuals who experience motor and cognitive challenges, while ensuring the interaction remained safe, reliable, and intuitive for daily medical use.

PROBLEM TO IDENTIFY

Patients with Parkinson’s Disease often face tremors, reduced fine motor control, and cognitive fatigue, which makes traditional mobile interfaces difficult to use. The challenge was to design an experience that accounted for these limitations while still supporting the complexity of insulin pump management. The solution needed to balance medical accuracy with accessibility, particularly for an older user demographic navigating unfamiliar technology.

To document my design exploration, I captured the original Figma board to show how concepts evolved based on the client references provided. I explored multiple layout and interaction options for each screen, iterating through different approaches before determining the most effective solution. Throughout this process, I maintained a dedicated component area in the upper-left corner of the board—tracking buttons, icons, and graphic elements—to ensure visual consistency and reuse across all screens.

After receiving feedback from fellow designers, I consolidated and refined the strongest ideas, revising key screens to narrow the direction down to the most effective solution.

RESULT

The final design centers accessibility, clarity, and user confidence:

Large touch targets were implemented to accommodate tremors and reduced dexterity, allowing for easier and more forgiving interactions.
High-contrast, vibrant color palettes were selected to improve visibility and support intuitive navigation for older users.
Color-coded actions provide clear visual differentiation between tasks, reducing confusion and decision fatigue.
Guided workflows walk users through each step of the process, offering clear direction and reassurance when interacting with unfamiliar technology.

The result is a thoughtful, user-centered remote control app that supports patients with Parkinson’s Disease in safely and confidently managing their insulin delivery.
