Since 2012, we have been developing pupil-based vital sign extraction algorithm

 Pupil-based HRV extraction System using infrared camera (Developed, 2017)

 Comparing with PPG (Photoplethysmography) sensor with pupil-based vital sign extraction algorithm, we found high correlation.

 Correlation with PPG sensor, BPM is 99% and HRV variables range from 91.8% to 99% based on data tested on 630 people

 We have developed out algorithm based on smartphone calibrating various noises (distance, hand shaking, eyeball movement and light).

 Just using smartphone and any device with RGB camera, you can get very accurate vital sign and stress index using our API and SDK

We provide a solution for measuring vital sign and stress index without using wearable with over 90% of accuracy
