They use IR (inferred transmitters aimed directly at the driver's eyes) and dedicated IR cameras (likely more IR sensitive only sensing IR with a smaller field of view aimed/focused directly at the driver's eyes). You could wear welder's glasses and they could track your pupils.Interesting. What’s the difference in how other OEMs track attentiveness?
Btw.. Not challenging your response,, I’m just not educated enough to understand it.
