It is estimated that many small partners have such a question, how does the smart wearable device calculate the number of steps?
The answer is here:
Most smart bracelets and watches use a three-dimensional rhythmic motion sensor. This type of sensor can sense motion such as acceleration or vibration in different directions by capacitive acceleration. Data recording is usually performed under the conditions of swinging arms, walking, running, cycling, climbing stairs, and the like.
For example, during our walking, the vertical and horizontal accelerations will change periodically, and the acceleration sensor of the smart bracelet or watch will collect data during this process.
Once the data is collected, your smart bracelet or watch will do the same.
The data of the three dimensions captured in real time, through filtering, peak-to-valley detection, etc., using various algorithms and scientific and precise logic operations, and finally transforming these data into readable figures of the smart bracelet/watch APP end, so that The number of steps, the distance, the calorie value consumed, etc. are presented to the friends.
