Interaction Design

Distinguishing between vestibular neuritis and stroke in a timely manner is critical. Through an agile design process, we created a digital interface and training guide for an emerging retinal diagnostic technology for use in the ER.

The Challenge

The nature of the emergency room is fast paced and structured. Verto is an emerging technology still under active development. My team was tasked with understanding the needs of the stakeholders, understanding how Verto fit into the existing ER workflow, and designing an intuitive user interface.

User Research

The goal of Verto is to create a technology that diagnoses vestibular neuritis in the ER. Currently, when patients arrive in the ER with dizziness, it is difficult to differentiate between stroke, a life threatening condition, and vestibular neuritis, a non-life threatening condition. To understand the stakeholders who would be affected by Verto and implement a solution that fits into the ER workflow, we interviewed Emergency Room professionals. We then created a journey map to understand how a patient who presents with dizziness as the chief complaint moves through ER.

From our user research, we learned that the ER is a complex, intense, and emotional environment. For Verto to add value, it must complement or improve the current workflow. Next, the interface must be intuitive, as the number of patients who present solely with dizziness will likely not warrant a dedicated technician. Finally, the interface must provide a quantitative result to assist the physician in determining the next steps for care.

Design Sprints

At the beginning of each sprint, we reviewed our previous sprint's design arguments to write the next sprint's design arguments. Using the design arguments, we then built prototypes, created a testing plan, and tested progressively higher fidelity interfaces.

Sprint 1 prototype

Sprint 2 prototype

Sprint 3 prototype

Sprint 4 prototype

We began by creating low fidelity paper prototypes and wireframes to understand the high level functions of the interface. In our later sprints, we moved toward a higher fidelity, digital interface. With each iteration, we tested with various medical professionals such as Emergency Room physicians, nurses, and imaging technicians to incorporate the needs of our stakeholders.

Final Pitch

We presented a video that served as a walkthrough of our digital interface and explained the basic principles of the technology. In our presentation, we emphasized how parts of our interface incorporated features from our insights such as: familiarity in the login page, intuitiveness through automated calculations, and guidance for next steps of patient care. Additionally, we recommended to the startup team future steps as they continue to refine their technology and prototypes.
