Test ‘n Go UI Redesign

Overview

At the height of the pandemic, my project team members and I learned about the issue of “spatial accessibility” to Covid-19 testing experienced by more disadvantaged populations due to geographical barriers among other issues. Because of this, we wanted to create a concept app for scheduling Covid tests for individuals with limited access to transportation through the idea of mobile testing sites. While we garnered some positive feedback from usability testing of our final prototype, there were also problems participants encountered that I wanted to address in this redesign so potential users would have an easier time understanding and navigating through the app.

Research Findings

Conducting a heuristic evaluation and finding problems with the existing design

I conducted a comprehensive heuristic analysis of our current app interface by using research-supported principles of usability and accessibility. This was in hopes of discovering areas of opportunity for improvement so potential users could navigate the app and schedule appointments with confidence.

Creating a New Identity

Establishing a brand guideline that makes sense and elevates the user’s experience

Building the User’s Confidence

Enabling users to move freely across screens with confidence

Making Consistency Key

Ensuring important buttons are in consistent and reliable locations

Consolidating Important Information

Enriching the homepage with relevant information for quick & easy access

Prototypes

Click on prototypes to play!

Onboarding through a smooth and simple interface

Viewing information about and bookmarking available testing locations

Completing the symptom survey before scheduling a Covid test

The Impact

While this redesign project was for a concept app, I wanted to see how it would potentially fare as a real app. With the little time I had left, I conducted 6 usability tests using The System Usability Scale (SUS) which consisted of 10 questions to which participants would have to answer from strongly disagree to strongly agree based on a 5-point Likert Scale.

Each participant took the SUS survey twice—one for the original and the other for the updated design. Here are the results:

26%

Increase in SUS score

82

Average score across 6 participants

Final Thoughts

  • This was a rewarding project that excited me since it was a chance for me to see how much I’d grown as a designer, but it also challenged me on how to prioritize which usability problems and screens to prioritize within my limited timeframe.

  • I discovered just how fun it was to prototype cool little animations in Figma and realized I could get lost in it for hours!

  • If I could go back in time, I’d want to:

    • Conduct user interviews with people likely to use this service to gain valuable and relevant insight.

    • Redesign the entirety of the application and focus on the information architecture.
