It's still vague beyond saying they trained an AI: "VitalLens is trained on the PROSIT and Vital Videos Africa dataset...The time-synchronized sensor array used for PROSIT consists of a video camera, electrocardiogram (ECG), pulse oximetry, blood pressure monitor, and an ambient light sensor. "
It's super cool. Thanks for sharing. I want to build a biofeedback app for meditation and this looks like a good platform to use.
