Original Miband Bracelet on sale

Many of my friends is the first contact sports such as miband bracelet pedometer product, so light and compact for bracelet can accurately count steps, even detailed and complete records of sleep feel very magical. This topic, and we talk about in detail the miband, which is how it works.

1.How the sports/pedometer steps data on watch comes?
A: To put it simply: millet bracelet can accurately count steps by both hardware and software algorithms composed indispensable.
Hardware: refers millet bracelet powerful built-in three-axis accelerometer ADXL362, military-grade, you know you want to achieve military-grade, it was more harsh. In fact, not a mysterious three-axis acceleration sensor, in most high-end mobile phones are equipped in acceleration sensor, but in the detection accuracy to reach the level of millet bracelet.
Triaxial acceleration sensor The three-axis refers to the space X, Y, Z three dimensions, with these three dimensions, can capture bracelet hand ring in use acceleration change, thereby generating the data.
Software algorithms: the data captured in real-time three-axis acceleration in three dimensions, after filtering, peak detection process, using a variety of algorithms and rigorous scientific logic operations, and ultimately transforming data into readable bracelet APP end figures, the number of steps, distance, calories burned value, etc. Display in front of the end user.

2, Sports pedometer function miband bracelet on what factors and relevant?
A: bracelet built-in accelerometer and algorithms are extremely delicate things. Overall, we get our hands on the ring for the first time in the setting, be sure to fill in all the honest and accurate information! Including gender, height, weight, age, these are not allowed to have a direct impact on a little acceleration sensor data capture and further affect the arithmetic operations, resulting in a pedometer is not allowed from the data is wrong, consume less calories numerical accuracy, so as to arrive not ideal data, affect your personal data movement.

Your arm posture, stride flatness, stature, road, uphill downhill pedometer will affect the value.



3. Why do some people think the bracelet is not precise enough?

Xiaomi bracelet in a range of memory in tolerance is a normal phenomenon. Bracelet using an acceleration sensor pedometer as the main basis, but due to the different levels of devices and algorithms used, and thus a bracelet sections inconsistent record the number of steps of the situation. Of course, with the sensors and algorithms excellence are inseparable.

Researchers have further optimized motion algorithms, to filter out as much as possible in daily life erratic motion gestures, the action (which we call "clutter filtering"), so that the accuracy of millet bracelet optimum.

Bracelet pedometer accuracy with people walking posture, walking habits are related, so we are not allowed in the face when you think of the data, try not to complain. The researchers will be better and better bracelet.
