Since last year, various functional bracelets and smart watches under the name of “health†and “sports†have emerged overwhelmingly, not only by those who are losing weight and like fitness, but also by some young people. fashion. Look at the "WeChat Movement" that has become a step in the wind, and you will know how much fire it is. However, these sports data is really reliable? Are these products really effective and reliable? The bracelet and the watch have essential differences The function of the sports bracelet is generally relatively simple, and quite a part of it does not even have a screen. It is small in size and mainly relies on sensor work, making it an entry level for the wearable family in terms of power consumption, price and experience. Some of them are equipped with a monochrome screen, which only shows the time and movement status, which improves the practicality. In contrast, smart watches are much richer. Motion detection is just one of many functions. GPS and heart rate detection sensors are often built in, but more communication functions need to be based on mobile phones. Otherwise, it can only be regarded as a complicated function. The electronic watch only, this is why smart watches know more people, less people use, the most important thing is that the standby time is short, up to two days. Factors affecting data accuracy Whether it's a sports bracelet or a smart watch, the principle of stepping is the same, that is, the shaking of the hand plus the displacement. The built-in high-precision acceleration sensor detects the displacement of the hand in space by using the acceleration integral to determine whether it is the number of steps. Why are some bracelets with high accuracy and some errors? First, the hardware difference, the controller cost of the high-precision acceleration sensor and the wristband are both double-digit starting, and the price difference of several precisions is several times. Second, the algorithm difference is also the data analysis. For example, according to the environment-aware algorithm, it can accurately determine whether the spatial displacement is caused by walking or running. In addition, the difference in peak acceleration between walking and running is very large, and the range of spatial displacement is often large. Therefore, you always have a valuable reason, you can't just look at the appearance. To ensure the integrity of the motion detection data, the bracelet can not be removed at will, even a bath (such as waterproof), to bring with you when you sleep. Mainly fun, the function has yet to be tapped Many people bought back the sports bracelet, thinking that they can only count, "WeChat Sports" has a lot of fun. In fact, this is only the most basic function. Download the corresponding APP. By inputting basic data such as height, weight, age, gender, etc., you can also get relatively accurate calorie consumption. For example, the calorie of a chicken leg is 300 kcal, at least 30 More than a minute can be consumed. Sports bracelets also generally have sleep monitoring capabilities, although the accuracy is controversial, but at least remind you to go to bed early. In addition, sedentary reminders and smart alarm clocks are also very useful features. Xiaomi smart bracelet light version Reference price: 99 yuan Recommended index: ★★★★★ Even if the light-sensing version adds the heart rate monitoring function, it only sells 99 yuan. Even poor students can afford high-tech, and join the mighty walking army. From the point of view of accuracy and function, the domestic bracelet is not worse than the imported one, and the applicability and user experience are also designed according to the habits and physical state of the country. The millet bracelet can reach 30 days in standby, can wear a bath, detect exercise and sleep. Quality, even support heart rate monitoring.
