Personal Health Record
Mobile App

Timeline

September 2021 - December 2021

Goal

Design a personal health record mobile app for patients to manage their health care on the go

Tools

Figma, Maze

Methodologies

Paper prototyping, wireframing, high-fidelity prototyping, usability testing

In the course, HF 770: Prototyping and Interaction Design, I designed a personal health record mobile app for an individual project. The project had six user story requirements, including various acceptance criteria, that the prototype would need to satisfy:

  1. As a patient I want to manage essential aspects of my Personal Health Record (PHR) using my mobile device so that I can manage my care while I’m on the go.

  2. As a patient I want a simple way to pay my medical bills online so that I don’t have to interpret complicated paper bills, write checks, or send payments through the mail.

  3. As a patient I want view my blood test results together with my doctor’s feedback so that I can stay up to date on my results and take appropriate action based on my doctor’s feedback.

  4. As a patient I want to send and receive secure messages to my care team so that I can coordinate my
    care without having to make phone calls for minor requests or deal with long hold times.

  5. As a patient I want to manage my appointments on my mobile device so that I can set up appointments while I’m on the go.

  6. As a patient I want to quickly and easily request and receive refills for my medications so that I can have continuous access to the medications without having to call my doctor’s office or travel to my preferred pharmacy to request refills.

Throughout the course of the project, I created paper prototypes, wireframes, low-fidelity prototypes, and high-fidelity prototypes using Figma. I conducted usability tests of the prototype with my fellow classmates and professor using Maze. I also annotated many of my designs to clearly communicate the functionality or purpose of specific elements to the class.

Paper Sketching

Paper Prototyping

After learning about the project requirements, I paper sketched designs to satisfy the requirements. By using this method early in the design process, I could quickly test ideas and easily make changes to the sketches.

Wireframing

Wireframing

Once I finished my paper sketches, I moved on to wireframing my designs on Figma. This included using basic shapes, symbols provided by Figma plugins, placeholder text, and a monochrome color theme.

High-Fidelity Prototyping

High-Fidelity Prototyping

After I completed the wireframes, I created high-fidelity designs of the app. During this process, I added color to elements and replaced most of the placeholder text.

Usability Testing

Usability Testing

Throughout the wireframing and prototyping process, I conducted usability tests using Maze. On this testing platform, my classmates and professor tried out my app while completing Mission tasks. After completing a series of tasks, they provided me feedback on their experience with the app. One feedback that I received was increasing the size of buttons for easier reach by both left- and right-handed users. Another piece of advice was providing information (e.g., in subtext or a clickable ⓘ icon) about a feature in the app that some users might not notice was interactive.

Key Takeaways
Key Takeaways

Throughout the course, I practiced many design methods, including paper prototyping, wireframing, and high fidelity prototyping. I became more experienced with using Figma, and I learned how to use a new tool, Maze, to create usability tests. I also learned how to apply various UX design concepts to my project; four that particularly stood out to me are the following: 

  • Thumb Zone: Increase width of buttons for easier reach with both left and right handed users

  • Colorblindness: Design a colorblind-friendly palette for accessibility

  • Button Placement: Place the button with the most “destructive” option farthest from reach to prevent errors

  • Language: Consider the wording of button labels, popup messages, and other elements and ensure they clearly communicate its message to the user
