Project Scope

The Pulseband is a wearable wristband that measures the wearer’s blood pressure, heart rate, steps, and sleep patterns among other vitals. It is specifically designed to also accommodate people with certain heart conditions. My team’s objective was to conduct robust user research and create a human-centered design to ensure the technology serves customers’ needs.

My Role

As the UX researcher and designer I conducted qualitative interviews and domain research, and synthesized this research using coding techniques and affinity mapping. Based on insights from this discovery phase I generated personas and a comprehensive set of wireframes. With my insights and understanding I also created the mobile application map and product roadmap.


Research began with a robust discovery phase, including domain exploration, competitor analysis, and a total of 22 qualitative interviews. Next, I extracted user concerns, motivations and goals to create a coding database using qualitative data visualization software nineteen. I distilled these insights with the help of affinity diagramming, from which emerged our larger guiding design principles.

One of the most interesting insights discovered during research was the need for in person, human-to-human touch-points and interactions, and for education to take place between people, not just between people and technology.

Less tech savvy users were asking to be shown in person how to use new technology, while health care workers requested that training be given to new users wanting to track heart health. However, service design was not in the project scope, so we included workshops and hands-on education in the product roadmap, shown below. The rest of the insights were within scope and addressed with overarching design principles.


Expressed need for human translation of data

Users fear both negative health content and quantity / frequency of content

Simplicity and ease with technology important

Medication is a major pain-point

Privacy should be robust

Users want to feel autonomous from wearable device and heart health issues simultaneously

Design Principles

Better heart health is simple and intuitive

Make help, tutorials, and discovery easy to find and ubiquitous

Provide education and dialog

Offer personalized health suggestions in app

Allow users to share data with doctors and family

Technology should be smart and silent

Concise content and less of it

Allow Pulseband to run on auto schedule

Personas and Requirements

To generate Pulseband’s personas I mapped users from my research database onto variable spectrums and then looked for people that clustered together. Based on these patterns I generated user archetypes with unique goals, concerns, and behaviors. I included Data Needs, Functional Needs, and Product Qualities as a reference to help inform my internal team in their design decisions.

Design and Ideation


Smart Heart

During research we found that our users were concerned about the quantity and content of the data they would receive from the Pulseband. We created our application to run in the background on an auto-check schedule that users could set up during on-boarding. We incorporated the Smart Heart coach that generates goals and suggestions based on data from the users’ own body to help them maintain optimal heart health. The product roadmap includes recruiting a panel of subject matter experts to aid in developing the Smart Heart’s repertoire.

Application Map & Functionality

  • Take blood pressure and heart rate either manually or automatically on a set schedule.
  • Provide easy to understand graphical data for BP and HR over time.
  • Interpret trends in BP and HR using Smart Heart so the user doesn’t have to.
  • Receive feedback from an Smart Heart coach to achieve goals and maintain heart health.
  • Send data over a period of time to a health professional or person of choice.
  • Track medication dosages  and supply, as well as keep a diary of any medication side effects.


Actionable Data

The Pulseband application provides a graph of blood pressure and heart rate data over time. It compares this data to averages based on the user stats entered during on-boarding. The Pulseband application can quickly show the user common trends in their HR or BP as well as suggestion better habits and goals. If concerned, the user is also able to send data to their doctor over a period of time they choose.

Blood Pressure Reading

I designed several dashboards and choose the final dashboard design below. The Pulseband can be triggered to take blood pressure manually by pressing the BP reading on the dashboard. A animated data visualization and confirmation allows the user to understand what is happening in the application. The new blood pressure reading is then dynamically updated on the dashboard.

Goal Setting

While it is important for the Smart Heart to suggest goals to the user, it is also imperative that the user be able to input their own personal goals. The Pulseband application also has a reminder option that will alert the user when to make another step towards their end goal.

Final Prototype

User Interface Design

Mid-Fidelity Mockups

After the first week and a half of research and ideation sessions and the resulting personas and design principles, I worked closely with my two other teammates who designed the user interface and developed the website. They used my wireframes as well as insights generated from word-mapping and brainstorming to create mid-to-high fidelity designs. I consistently made sure that the interface was designed with user needs and goals in mind as well as exemplifying our design principles.

Further Research Suggestions

My suggestions for future exploration and development involves designing a service plan that brings health care workers and heart conscious users together to educate one another as well as hold each other accountable. This necessarily means designing a second version of the Pulseband application to be used by physicians. My long-term research and design plan would involve holding workshops inside health care facilities to provide new technology education as well as cardiac health education.

In order for Smart Heart to be a viable solution Pulseband requires a board of subject matter experts who are qualified to help our team develop health suggestions and appropriate goal recommendations. I suggest we begin panel recruiting and attending conferences in the mid to long term. When we have an expert panel our users can trust that they are receiving relevant and effective feedback.
