How does the Algorithm works:
Detecting your face:
First of all we are detecting your face by a deep learning model
We are using a very low-light algorithm that processes the camera's frames with your face.
As part of our algorithm, we discover the r-ppg signal using signal processing so we know the frame your heartbeats and the time we have a peak in heart rate.
Calculating vital signs:
By verifying these peaks we know when your heart beats which give us the heart rate, oxygen saturation, and respiratory rate.
How much it takes to calculate the signs and show them?
It takes us about 9 seconds to show the heart rate and oxygen saturation.
Another 25 seconds to extract the respiration rate.
After ~1.5 minutes we have enough data to collect your HRV and Stress level.
