Project Scope

DizzyDx is a web-based platform created by a team of clinicians, Clinical Insights, to help physical therapists identify ailments based on symptoms related to dizziness. In addition to assisting clinicians in diagnosing patients, the platform is also used as an educational tool for students studying physical therapy.  My involvement in this project consisted of user co-lead user research to help influence design decisions for the client's final prototype.

The purpose of this study was to uncover users' experiences navigating the platform on both mobile devices and desktop during the high fidelity phase of the design process.

Client Goals

  • Gain actionable insights from user feedback to improve usability of the DizzyDx prototype.

  • Uncover any navigation related pain points reported by participants to improve information architecture.

User Groups

  • Students

  • Physical Therapists

  • Instructors

User Research

Usability Testing

This user research study consisted of 15 remote usability tests with all three user groups. Participants in the study were asked to provide information on sentiments, expectations, and experience while navigating the platform. Each user was asked to create a mock case study to discover the platform's recommendations based on a mock patient's reported symptoms.

We employed a thematic analysis of the feedback we collected from the study. The data collected from the usability test encompassed participants' sentiments, expectations, and experiences as they navigated DizzyDx. Through a thematic analysis, we were able to identify key findings that highlight pain points regarding navigation, user flows, and functionality.

Key Findings

Usability Issues & Pain Points

  • Participants struggled to find the right sections or categories to access specific information, leading to a sense of confusion.

  • The website presented an overwhelming number of options, which caused decision paralysis and hindered users' ability to progress smoothly.

  • Participants struggled to understand the context of certain pages or sections, as there was a lack of supporting information or cues to help them navigate or understand the purpose.

  • Participants reported experiencing navigation fatigue as a result of too many clicks within the user journey.

It's a bit frustrating the amount of steps it takes to get to the diagnosis information. Too much clicking involved.

User Delights

  • Some participants responded positively to the use of plain language applied to the navigation labels.

  • Participants enjoyed supportive features, such as the cited works feature that provides scientific evidence to support the platform's diagnosis of patients.

Conclusion

From this study, we were able to make recommendations to the client to pass along to the development team for implementation. Our recommendations included:

  • Revisit DizzyDx's information architecture by conducting a tree study to improve navigation and the overall user journey.

  • Limit the amount of information displayed to users on one page by identifying MVP content and consolidating repeated content.

  • Include content descriptions where necessary so users know what to expect as they navigate the site.
