Claim 1:
2. The method of claim 1, wherein images of said time series of face images comprise a set of landmark points of a face of the human and wherein applying said first ANN processing pipeline comprises:
extracting a set of time series of landmark signals at said set of landmark points from the captured time series of face images;
applying long short-term memory (LSTM) neural network processing and convolutional neural network (CNN) processing to said extracted set of time series of landmark signals to generate a set of processed landmark signals;
applying encoder processing to said set of processed landmark signals to generate a set of latent features; and
producing the first attention level indicator signal based on said set of latent features.
