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
