Evaluation of sleep quality
Depiction of evaluation of sleep quality
This algorithm including calculation of sleeping time, wake-up time, number of times wake-up during sleep and deep sleep time. Instead of the complicated instrument in clinical, this wearable device is much easier to use for evaluating sleep quality and sleeping time. By ambulatory measuring of sleep quality, it can depict the trends change in sleep quality for user manage their daily living habit.
Principle of Evaluation of sleep quality
Through the mathematical operation between return value from G-sensor and heart rate from HRV, we get the ratio of them. Then we can start the experimental test for searching appropriate threshold for sleep quality evaluation with the optimal accuracy.
