Benefits of Usability Evaluation in the Development Process of Diabetes Technologies Using the Example of a Continuous Glucose Monitoring System Prototype
Authors' conclusion
The evaluation provides valuable insights on how to improve usability of the prototype device and demonstrates the value of conducting structured usability testing prior to product finalization. The results reflected areas for improvement of the user interface, mainly by restructuring the IFU, provision of an additional leaflet, and device training prior to use.
Study context
- Population
- Intended users of a prototype FiberSense continuous glucose monitoring (CGM) System (single-use sensor and reusable detector), with and without CGM experience
- Participants
- 15 vs 15
- Comparison
- CGM-experienced vs non-experienced users
- CGM-experiencedn = 15
- Non-experiencedn = 15
- Outcome
- Usability of the CGM prototype
