LTR 150: Jonathan Kendler on Rethinking Human Factors Engineering for AI/ML-Enabled Devices

Summary

“AI brings novel risks and addressing them will require a more creative approach to human factors engineering.”

In this Let’s Talk Risk! conversation, host Naveen Agarwal speaks with Jonathan Kendler, a seasoned medical device human factors and UI design consultant, about how artificial intelligence is changing the practice of usability engineering in MedTech. Jonathan brings a rare perspective to the discussion, blending decades of experience in user interface design, human factors, and medical device development.

The conversation explores a central tension facing the industry today: while AI introduces new interaction patterns, trust challenges, and potential safety risks, the core responsibility remains unchanged - understand the user, understand the context of use, and design for safe, effective human interaction. Jonathan also shares where he sees real promise, including AI-supported training, surgical planning, and stronger cross-functional collaboration across risk, quality, regulatory, engineering, and human factors teams.

Key Takeaways

* AI-enabled devices do not eliminate the need for strong human factors fundamentals; they make them more important.

* One of the biggest emerging risks is lack of transparency around what the AI is doing and how users should interpret its output.

* Accuracy alone is not enough; teams must design for the reality that AI can fail and users must remain appropriately vigilant.

* AI may create meaningful opportunities to improve training, making it more interactive, adaptive, and competence-focused.

* Some of the most promising applications of AI are those that strengthen clinician judgment rather than replace it.

* Human factors professionals will need more creativity to anticipate novel use errors, misuse, and complex real-world interactions.

* Conventional usability testing may not be enough for AI-enabled systems, especially when risks like habituation emerge over time.

* The best outcomes will come from closer collaboration across human factors, engineering, risk management, quality, regulatory, and safety teams.
