How it works
An AI guide called Dr. Aria talks the user through a short session in plain language, then produces a health report. One video session is designed to capture:
- Heart rate, from remote photoplethysmography: skin color changes on the face
- Facial expression, tracking landmarks for reduced expressiveness
- Voice, jitter, shimmer and MFCC features
- Tremor, from positional jitter in facial keypoints
- Bradykinesia, from finger-tapping speed and amplitude
The accuracy figures in the deck come from the published research it cites, not from a test of this prototype, and it isn't a clinical tool.
