Surprised Apple didn't discover this - or maybe they did and just didn't think it was a big issue. Could this be part of the reason behind the try-on appointments, so people with tattoos/scars/hairy arms can make sure all the features work correctly before purchase? Edit: Also, why does the comment section here look like a reddit thread?

Anecdotal at best, but I have noticed a slow decline in % of quality posts per comment thread over the last 3 or 4 months. This problem is also much more apparent when the article is about something that is easy to comment on (non-technical discussion) and one that has large groups of cult fans and detractors that will blindly support or badmouth any newly released information (apple products are probably #1). sorry…

I've also been reading comments like this since I arrived here four years ago (just looked that up, wow is that depressing). Not that it means they're all wrong, of course, but I suspect this is nothing new. Or maybe I'm the problem.

So I have a basic understanding that blood is red due to the chemical bond between iron and oxygen, and how both elements together reflect light, but out of curiosity, can anyone touch on the significance of green light?

The section "The science behind Apple's sensors" in the article contains some details about that.

Quick google search returned this: https://en.wikipedia.org/wiki/Photoplethysmogram

According to this: http://bsn2014.org/poster/BSN2014-poster09s-maeda.pdf Green light seems to be used to lessen the impact of motion on the measurements.

This is where Steve would've stepped in and said if you want tattoos use Android Wear.

Do you think steve would have let the current iwatch, as is, go to market? So many little flaws.

Did he let iPhone 4 "antennagate" on the market?

"You're wearing it wrong."

Joking aside, if this watch uses the green and infrared LED method, there's really no fix here. The Moto 360 and other watches use the same technology. If the LED light is being blocked by ink, well, too bad.

Green light absorbed by the red blood, heartbeats change how much blood is below the sensor -> be measuring how much light is (not) reflected it can work out the pulse. (it also has a mode using infrared light, but that is used only in special cases)

Earlier quoted context omitted.

Nailed it. I expect to see that headline soon.

side question, why is everything "*gate" nowadays? surely it's not a throwback to watergate? I mean, that's 43 years ago nearly.

I'm just waiting the day Bill Gates slips up. Then we'll have Gategate!

Sorry hipster, can't have your cake and eat it too

you and @jgalt212 seem to believe tattoos are an exclusively hipster thing... which implies that you believe that having tattoos is somehow a mark of a shallow, transitory nature or perspective... which naturally leads one to conclude that you two are in some way above it all... ...you hipster fucks

at least they're real hipsters and not the trendy pseudo ones

I suspect -- but have no proof whatsoever -- that Apple is the target of a widespread astroturfing campaign. The quality of other subjects on HN seems to be close to the normal (high) quality. Threads involving Apple, on the other hand, see an immediate influx of stupidity. As the downvotes accumulate, the thread drops of the front page.

I realize that Apple has always been controversial, but this seems to have become especially egregious since the sometime around the beginning of the year.
