Have you considered a microphone-based solution that analyses fatigue levels from voice in near-real time as a solution as an extension or a
Voice changes caused by increased fatigue can be detected with commercial vocal biomarker technologies. A transportation operator monitoring system built using this technology could help detect fatigue and reduce fatigue-related accidents.

It’s noted that NHTSA, FHA, FAA, etc. have had success with similar systems. Why haven’t these systems been adapted for this use case?
Is there an inherent challenge of this use case that makes those systems unsuitable?

Would a solution that incorporated a non-intrusive wearable device be in scope?
Or should the solution operate completely passively without interacting with the operator?

Locomotive engineer standard PPE
When in the work context, are locomotive engineers assumed to be wearing any particular personal protective equipment, such as helmets, glasses, gloves, etc., that might limit camera and/or physiological sensor access?

Would solutions that do not propose camera-based solutions be considered for this topic?
We have a solution that provides behavioral indicators of fatigue in near-real time but does not include a camera system. Would this alternative solution be considered for this topic?

Would you consider a wearable system that has shown to beat out eye-tracking in monitoring fatigue level in real-time at a lower cost?
It seems from the questions that the primary interest is around eye-tracking. We build a highly discrete and modular brain sensing system that has beaten out eye-trackers in real-time for fatigue at a lower cost. Please see a paper we published with Graz University that had our system beating out medical grade eye-trackers and other forms of fatigue monitoring. https://www.nature.com/articles/s41598-022-05810-x

Are you looking for a system to only assess operator fatigue, or would it be desirable for it to also be an alerting system?
For example- to provide alerts to either the locomotive engineer or to a supervisor when fatigue levels pass a certain threshold
