| One (or more) of the articles I read stated clearly that dark-pigmented skin was not an issue at all, just the ink in tattoos. This shows how many things have to be considered when bringing a completely new product to the market! Who would have ever thought that a tattoo would be a problem for a watch!!  /\__/\_____ (=-.-=),,__,,_)~~~~ /\„,„/\ ( =';'= ) /*♡♡*\ (.|.|..|.|.) -------Original Message------- Date: 04/30/15 07:08:11 Subject: Re: [iPad] Apple Watch wrist detection failing with some tattoos, users complain Do you mean to say that Apple Watch may not work for coloured people? With best wishes, P. K. Saha Apparently the sensors are unphased by dark skin color but it's theorized that the metal in the ink is messing with it. I'd assume that they are hard at work on this. It's not like California is without tattooed individuals, 😜 ~KLM \\ "Antisocial behavior is a trait of intelligence in a world full of conformists" ~Nikola Tesla // No problem here. I heard this on the news today, but am glad that you posted this, so I know the why. I hope that they fix this & soon. Toby Sent from my iPad Oh no. Apple Watch wrist detection failing with some tattoos, users complainBy: Roger Fingas Tuesday, April 28, 2015 10:34 AM
 Image Credit: Reddit user guinne55fan One owner noted in a Reddit post on Monday that when he wore his Watch on a wrist tattooed with black ink, he couldn't receive any notifications, and the device would lock every time it went dark. Before trying to contact Apple, though, he tested the Watch against his unmarked hand, which suddenly allowed it to work as intended. Turning off wrist detection entirely was said to solve the problem, but at the expense of features like Apple Pay. Wrist detection relies on light sensors on the back of the device which also serve as a heart rate tracker through a method known as photoplethysmography. By flashing infrared and/or green LED lights, the Watch can detect blood flow. Dark skin color could theoretically affect accuracy, although Apple states that the Watch will increase LED brightness and sampling rate to deal with tough reads. The issue could be down to the materials that tattoo ink is made from. Many pigment bases are derived from heavy metals, like mercury, copper, or nickel, which may interfere with the sensors.
