As the average human reaction time is 0.19 seconds, I don't see 8FPS too bad for a start. More FPS is always nice, of course.



Reaction times and flicker fusion rates[0] are orthogonal. 0 ms latency at 8 FPS is different than 190 ms latency at 120 FPS. E.g. If there is an event that takes less than 125 ms, at 8 FPS there is a probability that you would miss it entirely! At 190 ms latency with 120 FPS, you would be guaranteed of seeing a 125 ms event, but processing of that information would take 190 ms longer.

interesting comparison but it is a bit disingenuous

there is more going on than just input in that reaction time figure

8fps fails to assume a reaction time of 0.125s for the same reason that the human eye's ~220fps.. now this is a mental stretch of the true underlying mechanisms but i'll make it for sake of consistency of argument(o).. fails to imply a reaction time of .00454545s

i guess i assumed autonomous vehicles sensor data would be measured in hertz, but now am intrigued by what framerate the computer vision system works
