Xiaomi MIUI officially announced that the MIUI 12 system will add a heart rate detection function. Xiaomi Mi Health Update to version 2.8.6 to support the heart rate detection function, which is also the first system-level heart rate detection in China.
The Xiaomi healthy heart rate detection function does not require additional hardware, and the heart rate can be measured through the camera. The principle is to use the flash next to the camera as a continuous light source and to lightly touch the camera with a finger to obtain an image of blood flow. Through image analysis, a stable pulse wave signal can be collected to obtain the heart rate value.
In addition, Xiaomi Mi Health Update can also present classified detection reports for different exercise states, and the heart rate evaluation is more scientific; the self-developed local AI heart rate recognition algorithm is used to identify accurately while protecting your privacy.
In terms of supported models, almost all MIU 12 models support Xiaomi’s healthy heart rate detection function, except for the following models: Xiaomi CC9e, Xiaomi CC9Pro, Xiaomi CC9 Meitu customized version, Redmi 6A, Redmi 10X Pro.
Xiaomi said that camera performance is different on different models. After testing, Xiaomi Mi Health Update is found that the unstable frame rate when the camera collects images will cause the result to deviate greatly from the true value. For better user experience, Xiaomi closed the heart rate test entrance on the above five models. Xiaomi will still find solutions and solve the problem as soon as possible.
