Pulse Band is a conceptual fitness wearable that tracks steps, sleep, heart rate, blood pressure, and other vitals. The device is specifically targeted towards those who are at risk of or have certain heart conditions such as high blood pressure.



Time Frame:

3 Weeks

The Challenge:

My 3 person team, as part of this exploratory project, was tasked with designing a companion app to allow users to gain actionable insights into their heart health and physical activity. My team used Scrum methodology as well as Google Venture’s 5 day sprint outline throughout the duration of this project.

My Role:

Lead UX and interaction designer

  • Conduct user and SME research
  • Facilitated research synthesis process and the development of requirements definition and user personas
  • Participated in the collaboration of ideation and feature development
  • Sketched wireframes, created tappable and interactive prototypes, and conducted usability testing


  • Weekly progress reports
  • User personas
  • Application map
  • Annotated wireframes
  • Prototypes
  • Final presentation to stakeholders


Research Plan

My team began by creating a plan for conducting research with subject matter experts and with potential users of Pulse Band and its companion app. We then summarized our plan into a one-page plan that we could show to stake holders.

Conduct Research

SME research focused on learning about various aspects of heart health and areas where patients struggle while user research focused on learning about their routines surrounding their health and physical activity, their technical competency, and their struggles and successes in maintaining their heart health. The end goal was to gain empathy for the people we talked with so that we might have a clear understanding of what problems exist.


Research Synthesis

Having talked with a variety of subject matter experts and users my team and I then distilled all the information we had gathered through affinity mapping to find trends, uncover mental models and identify problems.

User Personas

User personas were created to not only bring the research to life but to also help us make sure ideas and solutions were being focused on the goals our potential users might have.

Design Principles

My team also wrote several design principles to check our ideas against.

  • Simple and easy to navigate
  • Approachable, practical, trustworthy
  • Meaningful data via actionable insights
  • Utilize social connection and interaction to increase motivation


User Scenarios

As lead user experience designer on my team I facilitated a variety of activities to help my team ideate on the various problems we identified. We began by creating user scenarios to imagine what it might look like for a user to interact with the app throughout their day.

Sketching and Wireframes

I also facilitated time-boxed ideation sessions where my team and I sketched ideas and wireframes for various features and flows of the app.

I drew out my wireframes by hand first, asked for feedback from team mates, others in the open office space, and potential users. Ideas were then iterated upon considering the feedback I received.

Prototype & Test

Low Fidelity Prototypes

Several prototypes were created throughout the duration of the project. I first created a few protytpes using Marvel and my hand drawn wireframes. These prototypes were tested with users to check the flow of the main features of the app as well as test different concepts surrounding the goal setting feature my team was working on.

Mid-fidelity Prototype

Using the feedback from our lo-fidelity prototypes I then iterated and created a prototype using Sketch and Marvel to further test the concepts my team was working on.
