The dataset consists of facial video recordings of 14 subjects (8 male, six female) under different engagement activities such as reading a webpage, talking about their day, watching a movie trailer and deep breathing. It also contains videos when they were stationary to establish a baseline. The video for each activity is 2 minutes. Ground truth PPG data were collected simultaneously using an FDA approved pulse oximeter.
