Whether it is a foreign fitness tracker brand or a domestic brand, the core function of the fitness tracker is to help users better manage their health, which is very helpful for our daily sports.
So, is the accuracy of the fitness tracker’s step count, calorie consumption, deep sleep time and other data reliable?
The fitness tracker step counting principle is actually based on the three-axis acceleration sensor to achieve the number of tracking steps, as long as the hand moves, it can be recorded. Many smart phones have this capability, and the pedometer function can be implemented by a combination of built-in smart sensors and software.
In fact, we can judge its accuracy from its step-by-step principle. If you sit in a chair and shake it, it will record the number of steps. The fitness tracker will filter out the discontinuous vibrations. There are some requirements for the walking action. Not all abnormal walking can be counted in the walking step, and some errors should be normal. Eating, brushing, etc. can lead to miscalculations. For example, if you go to the supermarket, push the stroller, etc., the hand movement data collected by the fitness tracker may not accurately determine the user’s movement status. The situation of the step.
However, the fitness tracker records the user’s daily walking situation and target achievement rate through built-in sensors, and records the movement trend over a period of time to help understand and analyze the user’s health habits, which has certain reference value.
