One place I worked had indirect solar spectrum light that bounced light off the ceiling. That really seemed to keep my eyes from getting tired.

#42If you wish to use an e-ink screen to avoid eyes strain, I've recently learned that a video projector does have the avantages of a classic monitor (colors, good refresh rate) without having to watch directly at the source of light, thus avoiding eyes fatigue. I consider it to be a better tradeoff than working with an annoying delay as if you were using a 10 years old computer.
How does backlit of reflected make a difference? Light comes of the screen/projection and hits the eye. I don't see how the light would change with that bounce by projection.
If you don't wish to look at reflected light either, in that case you might as well be blind :). Even from en e-ink screen, you are watching reflected light from another source arriving into your eyes _after_ reflecting from the e-ink screen.

I guess that depends on how strong your projector is, because the light bounces of the wall/screen back in to your eyes.
As does the light when it reflects off of the screen of your e-ink display, right?

#44Seems like it'd be a good screen for a system that's intended for use outdoors. A lot of surveying hardware hooks up to a conventional laptop, but it's difficult to see laptop screens in full sunlight, and you either have to put a shade over the screen or leave the laptop in the cab of the truck.
How does E-Ink compare to LCD in temperature range?

That's because the sun is really bright. You might just as well just dim your screen. A bit like these sun solace sunglasses :)
it is NOT the same at all. There is a lot to this that you're obviously ignorant of. There is a big difference on your eyes, brain, and sleep cycles between transmitted light and reflected light even when your screen is set to a low brightness.
How can there possibly be a difference between transmitted and reflected light? Once they head for your eye, a photon is a photon. The only distinguishing features they have are direction, polarization, and frequency. Your eyes can't even theoretically distinguish between emitted and reflected light of equal spectrum and brightness.

#46Does anyone know if there's a hack for Kobos or Kindles that allows for similar? Or connect a keyboard. I'd love to be able to attach a tmux session on my Kobo Glo HD and write with a bluetooth keyboard outside in the summer.
Kobos have proven to be pretty hackable, IIRC someone on the mobileread developers forum got Debian running on one, so ssh/tmux should be possible.
The refresh rate is pretty low though, even for a text based terminal, I suspect interactive use would suffer.

Can you describe that in a bit more detail? Links? I'd love something like that.

I don't know about eye strain, but my brain can very easily tell from specularity cues whether I'm looking at a passively lit or back-lit screen. This matters because my brain apparently associates back-lit screens with wakeful activities and keeps me from going to sleep. My brain can't really tell the difference between an E-ink screen and a book (when illuminated by ambient light), so I prefer to read on an E-ink screen before bed.

#49I wonder why Pixel Qi didn't become popular enough to fit this niche and not die as a company - seems to have many benefits over e-ink, including refresh rate and some colors: https://the-digital-reader.com/2015/01/12/reports-death-pixe...

I dunno, maybe you could hit up Toshiba and ask them why they stopped putting transreflective screens on their laptops as well: https://www.youtube.com/watch?v=WXO7u6bzVGQ

#50Earlier quoted context omitted.
For a non-PWMed high DPI monitor adjusted to match the e-ink's brightness and contrast, the only difference in the light hitting your eye is the spectrum and the polarization. It's not completely impossible for these to matter, because of interactions with optical imperfections of the eye, but I've never seen any evidence that it actually does matter.
What about blue light? I've been hearing about that being a problem lately.
You can use f.lux https://justgetflux.com to compensate for that.
