Millions of people suffer from heart conditions like high cholesterol, atrial fibrillation, and angina. Pulseband is a fictional wearable device designed to help those with heart conditions live full and satisfying lives.
Key to the research phase was understanding users' motivations and day-to-day activities, so that Pulseband could best integrate into users' daily routines. Guided by an exploratory research plan, our team gathered, transcribed, and analyzed over 18 ethnographic interviews spanning the demographics of our proto-personas.
Through affinity mapping exercises, a set of personas emerged. Our team then storyboarded scenarios that would form the basis for user flows, information architecture, and low-fidelity prototypes.
Rapid prototyping began with paper using PoP iOS, and the best ideas moved into Axure RP. Ultimately, our team created 95 wireframes, rooted in the design principle that Pulseband should be 'one less thing to worry about.'
Though we were prepared for iteration, usability testing using low-fidelity wireframes yielded positive results. Our team attributed this success to our methodical dedication to personas and storyboards throughout the design process.
An exploratory user research plan, rooted in proto-personas, identified key research goals, and methods that would help us meet those goals.
After conducting, tagging, and affinity mapping data from 18 user interviews, our team converged upon an important insight: users don't want to think about heart health when they don't have to.

Personas and storyboards became the key tools for distilling data from user interviews. These tools would ultimately help our team stay true to user motivations and real-life use cases.
Armed with insights, personas, and scenarios, our team moved forward into early stages of information architecture, user flows, and prototyping. We created a set of design principles to help hone these iterations.
Users didn't want to think about their heart health - they wanted to focus on their day-to-day activities. Pulseband had to give users one less thing to worry about, not one more.
Our team sought to create in-and-out interactions. While the Pulseband app had potential to overload users with information, we prioritized screens that communicated a key message in 3 seconds or less.
End-user research indicated a reluctance to act on signs of heart disease, and healthcare providers echoed this concern. For Pulseband to fulfill its role, it had to propel users towards a clear path of action.
I used the UI designer's high-fidelity mockup to demonstrate the interactions depicted in our storyboards.
By drawing a continuous line through all stages of the process – research to personas, scenarios to flows, design principles to prototyping – our design decisions achieved positive reactions during user testing.
