“Philips recently launched an iPad app, Vital Signs Camera, that measures the user’s heart rate and breathing via the tablet’s front-facing camera. The $0.99 app, available only for the iPad 2, is intended for entertainment purposes only.
The app measures the users heart rate by determining blood flow to the face based on the color of the users skin, and breathing rate by analyzing the motion of their chest. Users place the iPad on a table and position their face inside the marked area designated within the app.”
