Tattoos Found To Interfere With Apple Watch Sensors

An anonymous reader writes: A number of early Apple Watch adopters have complained that their tattoos cause interference with many of the new product's key features. According to multiple tattooed sources, inked wrists and hands can disrupt communication with the wearable's sensors installed in the underside of the device leading to malfunction. Owners of Apple Watch have taken to social media to voice their frustration using the hashtag #tattoogate and sharing their disappointment over the newly discovered Apple flaw. One user reported that the Watch's lock system did not disable as it should when the device was placed on a decorated area of skin – forcing those affected to constantly enter their security pins. A further source suggested that notification alerts would fail to 'ping' as they are supposed to, and that heart rate monitoring differed significantly between tattooed and non-tattooed wrist readings.

It's not a new idea. These sensors have been around for decades and are used in hospitals routinely.

I see a complete picture, a canvas I guess you could say, all these elements brought together to express the physical state of a person; it even goes so far as exactly how they move, what expressions they show, and, of course, what they're wearing.

      After taking all that in, I decide what category of attractiveness she falls into, if she's sexually attractive, if she's intimidating, or whatnot. All the normal stuff. You'd be surprised how much sexual attraction falls squarely on a good smile, a good voice, body movement, the emotional regard of personality (yes, even for a sociopath with no real empathy). The first look is to see what image I'm looking at, how it flows, and how visually pleasing it is; the second is to see how I feel about it, if I want it, and what I want it for.

    What else affects your reading?
    Many factors can affect the performance of the Apple Watch heart rate sensor. Skin perfusion is one. A fancy way of describing how much blood flows through your skin, skin perfusion varies significantly from person to person and can also be impacted by the environment. If you’re exercising in the cold, for example, the skin perfusion in your wrist may be too low for the heart rate sensor to get a reading.
    Motion is another factor that can affect the heart rate sensor. Rhythmic movements, such as running or cycling, give better results compared to irregular movements, like tennis or boxing.
    Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.
    If you’re not able to get a consistent reading because of any of these factors, you can connect your Apple Watch wirelessly to external heart rate monitors such as Bluetooth chest straps.
    Heart rate is just one of many factors that Apple Watch uses to measure your activity and exercise. Depending on your workout, it selects the most appropriate inputs for that activity. For example, when you’re running indoors, it also uses the accelerometer. When you’re cycling outdoors, it uses the GPS in your iPhone. And even when you’re not in a dedicated workout, it tracks how much you move each day. So Apple Watch can give you the information — and the motivation — to improve your fitness and your health.
