Not just humanoid robots, but any robot using cameras. Another interesting issue is with led headlights and tail lights, because the way they maintain their brightness is by pulsing, if the framerate is synced with the pulse your self driving car never sees the brake lights or something similar

Thats why cameras shouldn’t be the only thing used for self driving Lidar would just detect the car getting closer

That's what the camera does, it's not looking for brake lights.

Otherwise broken tail lights would cause so many accidents.
Not to mention every other obstacle without lights on it

I always wonder if I'm especially sensitive to the flickering on those lights or if the ones that annoy me are all defective in some way that makes the flickering more noticeable. I hate them.

There are a few different ways to design these electrical systems. A cheap one like Christmas lights will flicker at 60hz or 120hz depending on design, both of which some people can detect.
I absolutely hate it.

UK electricity is 50 Hz, visitors from USA (60hz) see flickering. Long florescent tube lighting you find in offices was the worst.

you can also find plenty of DC Christmas lights with no flicker at all. downsides are they have a brick to plug in and they can't be daisychained as much. I've got some strands that can be daisychained up to 300ft/91m - these cover the vast majority of home use cases, and the lead between the plug and first light is about 20ft/6m so it's usually possible to combine multiple sets. I once had 12 strands on one tree and while that required 3 plugs, it was something like 60w total so I just used a 3 outlet end on a 16awg extension cord

Are you colour blind?
TheGrumpyre t1_jeb7k71 wrote
No. Do you think that would make a difference? I would assume that would only affect the cells in your eye that detect the difference between wavelengths of light, not the ones that detect changes in light intensity. Unless it's one of those things where you become more attuned to other kinds of visual input to make up for the lost data.
frivolousfry t1_jeb9wdy wrote
Indeed it is. There are two different types of cells responsible for visual stimulus. "Rods", as they are known, are responsible for differences in light intensity while "cones" are responsible for colour differential. Colour blind people don't necessarily have less eye cells overall, but rather a deficiency of cone cells. The totality of cells is comparable to a normal sighted person and the lack of cones is made up by rods, which in turn can cause an increase in light sensitivity for colourblind individuals.

A self driving car doesn’t need to look for break lights noir headlights. I guess you could run into this issue with something like a traffic light (not at all sure if these work in the same way you’re describing). Either way, an issue like this could probably be solved really easily with regular standards since neither frequency change over time.

Could this be resolved by using multiple cameras that capture at different intervals?
