What is one main benefit of focusing on human factors in device design?

Focusing on human factors in device design primarily enhances safety and usability for the end user because it emphasizes understanding how users will interact with the device. This approach ensures that the design takes into account users' physical and cognitive abilities, promoting ease of use and reducing the likelihood of user errors. By prioritizing human factors, designers can anticipate potential challenges and create intuitive interfaces, which ultimately leads to safer and more effective devices. This not only benefits the users in their everyday interactions but also complies with regulatory standards that emphasize user safety in medical devices.

While other options may have their own merits, enhancing safety and usability directly addresses the needs and concerns of the end user, making it a cornerstone principle in device design.
