LaCause

Heart rate, HRV, and head pose — from a standard camera

Using proprietary rPPG technology, LaCause captures heart rate, HRV (heart rate variability), and head pose from standard RGB cameras on PCs, smartphones, and tablets — all non-contact. Biometric signals are converted into physiological markers such as activation and attention. No recording, no audio, no facial image storage — privacy by design.
