Is the fortune-telling in snail's sleep accurate _ Is it true that snail divines in sleep?

What is the principle of an APP like Snail Sleep? How do you know my sleep?

Principle: Snail Sleep App actually measures your sleep state by detecting your sleep activity through the acceleration sensor of your mobile phone.

Snail sleep uses acceleration sensors and microphones to recognize human movements and sounds from two dimensions, and at the same time uses body movement algorithm to perceive the sleep cycle and state of human body. Moreover, the human motion algorithm has passed the medical-grade comparative experiments in Air Force General Hospital, Tsinghua Chang Gung Hospital, Coal General Hospital and other places, with an accuracy rate of 76%.

The principle of people's sleep is that when they sleep deeply, their weight will sink. Use the gravity acceleration data of the bed to judge your sleep state.

How to detect snail sleep;

Use the microphone of mobile phone, gravity sensing and gyroscope to detect.

Including the scale of our turnaround, we can only say that it has certain reference value.

Sleep report

The recognition algorithm of snail sleep has been tested and compared by a large number of professional sleep laboratories, and compared with the sleep data of professional EEG and ECG sleep monitoring equipment. Match and optimize the sleep algorithm for different types of devices such as iphone4, 4S, 5, 5S, 6, 6Plus to ensure the accuracy of the sleep algorithm.
