Movement is as much a visual pollution as light is. I find it very, very distracting. That is perhaps a cognitive defect on my part. The fact that e-ink screens will be relatively static is only a good thing in my book.

Another complication might be that e-ink by itself is not visible in the dark, though it isn't a problem to add lights. However, that could again be a benefit.

Personally I would love a ban on ALL advertisement in public spaces, even print. Some brave politicians have done it on a city level, and the citizens just love it. Banning moving images and lights for advertisement would be a compromise, e-ink screens could then still be allowed.

I find more so, especially when it happens in my peripheral vision. It can be irritating enough for me walking past overly animated displays in shops, I bet it could be dangerously distracting for some drivers (who aren't always giving as much attention to the road ahead as they should be anyway) going past street or shop window signs.

Does backlighting eink work? I think all the hand-held displays I've experienced have been lit from the sides. That is probably practical though: the old posters-on-a-roll setups seen in highstreets were often lit that way and with modern bulbs it wouldn't consume as much power these days.

I would be wary of that loophole. I've seen some impressive displays of quick refresh rates for e-ink, so playing distracting video content would be perfectly possible assuming those techniques scale to this size, and if advertisers can do it they will whether it is good for anyone else or not.

The human brain has cognitive subsystems devoted to detecting motion that seems non-random, that is, that seems to move with deliberate purpose contrary to other motions like leaves or ripples. It's important for predation on both sides—for the predator or the prey.

That's also exactly why advertisers love it and will continue using it. They will buy any politicians who look likely to ban moving images or lights.

It's not only you. Movement in general is a preattentive feature, meaning that it gets processed subconsciously and appears to "pop out" in an image.
