Shaping Medical Device Development Through Early Usability Testing
Challenge
The client needed to evaluate the usability of three early design belt concepts and GUI messaging to:
Ensure users could understand charging states and progress indicators on the external charger
Enable users to comfortably align the external charger to the implanted battery while wearing a charger belt
Solution
The team planned and executed a focused formative usability study to test early design concepts with intended users:
Targeted Recruitment: Intended users (both male and female) living with the heart condition participated in the study
Realistic Environment: A simulated home setting featuring a one-way mirror allowed the client team to observe sessions in real-time while maintaining continuous communication with the study team
Adaptive Approach: GUI icons that confused participants on Day 1 were updated overnight and re-evaluated with participants on Day 2
Efficient Timeline: Within just two days, the team gathered critical insights about usability challenges and user feedback, delivering a comprehensive results presentation to the client within two weeks
Results
The study provided key insights enabling the client to revise prototypes quickly, preventing costly mismatches between user needs and future product designs. Specific outcomes included:
Enhanced User Interface: Improved user interpretation of messaging on the device interface
Inclusive Design: More comfortable and adaptable charger belt design
Aligned Expectations: Better correspondence between instructions for use and actual user expectations
