Point-of-Care (POC) Device

Methodology

  • Two rounds of formative usability studies
  • User groups: Medical Assistants, Registered Nurses, and Medical Lab Technicians
  • Think- aloud technique
  • Simulated their environment
  • Qualitative analysis

Project Description

This project focused on the concept development stage of a Point-of-Care (POC) device intended for use in Clinical Laboratory Improvement Amendments (CLIA)-waived clinics. The device was designed to enable rapid and reliable testing for Sexually Transmitted Diseases (STDs), specifically addressing the needs of resource-constrained clinical environments.


Responsibilities

  • Led and conducted research activities, including developing research protocols, managing logistics, creating recruitment screeners, drafting usability scripts, analyzing data, and presenting design recommendations to the client for the next project phase.

  • Conducted evaluations of user interactions with the device and its interface.

  • Contributed to human factors documentation, including the usability engineering plan, critical task analysis, use-related risk analysis, and user interface specifications.

  • Collaborated with a cross-functional team consisting of a client, a program manager, a UX designer, an industrial designer, a mechanical engineer, a systems engineer, and an electrical engineer.


Impact

  • Identified key design directions and areas for further exploration in the next round of study.

  • Secured approval from the client for an additional round of formative usability studies before moving to the Alpha design stage, including budget and timeline approval.

  • Achieved a perfect client satisfaction score of 5 out of 5 for the UX team.
