Human Factors Engineering in Medical Device Development

This technical report outlines the critical role of human factors engineering (HFE) in the development of medical devices, emphasizing its necessity for regulatory compliance and user experience enhancement. It details how HFE has evolved from a supplementary consideration to a fundamental expectation by regulatory authorities, including the FDA and international standards such as IEC 62366-1. The report explains the integration of HFE into risk management processes, highlighting the importance of user-centered design principles that involve comprehensive user research and iterative testing. It discusses the merging of HFE and user experience design, which aims to create devices that are intuitive and safe for a diverse user base. Furthermore, the report presents trends in HFE, such as the use of smart devices and AI, which introduce new usability challenges that must be addressed. The document emphasizes the necessity of early user engagement in the design process to mitigate potential usability issues and enhance product marketability, ultimately aiming for devices that meet real-world needs.
