You have dark tattoos on the wrist? Watch Apple puts up a fuss – The New Blog Times

Because of the technology involved, it would seem quite normal that Apple Watch has difficulty detecting the beat heart on a dark tattoo.

Rome – It seems that the first observation comes from a Twitter user: “It seems that people with tattoos pulse can not use the Apple Watch for Apple Pay, because it can not detect if you are alive. Fun! “, Writes Steve TS.

The news immediately taken up by the Mirror that the British and guidance on Reddit, made the rounds of the network. Pretty ironic that Apple Pay platform recently found to be in great (and silent) growth, see put spanner in the works for some simple tattoo.

The question would seem to be because the Apple Watch detects the heartbeat through a flashing green LED, located below. From the detection of the reflected light then proceed to calculate the heart rate.

Obviously a dark tattoo can alter this survey, bringing the smartwatch to … funny conclusions about the state of existence in life of its owner. The Reddit user has in fact tried to keep the watch on the hand, which does not have tattoos, and there did not appear any problems.

The event is clearly explained on the website of Apple: “Even in ideal conditions, the Apple Watch can not be able to get a reliable reading of the heartbeat for all. And for a small percentage of users, various factors may make it impossible to completely read the batttito cardiac ‘.

The page illustrates a design with the back of the watch, of which there are two green LED light and infrared, as well as two photodiodes used as light sensors. Where a tattoo dark alter the propagation of light waves, the photodiodes may receive a return signal so low as not to be measurable.

So it is clear: Apple is unlikely to change the project. Needless to talk about “tattoo-gate”, along the lines of what, in relation to the iPhone, it was called “antenna-gate” and that aroused kilometers of words you want the Apple Watch? Tatuatevi not the wrist. Or … wait for the Apple Watch 2.
