Claim 6:
7. The system of claim 4, wherein images of said time series of face images comprise a set of landmark points of a face of the human and wherein said processing circuitry applies said first ANN processing pipeline to:
extract a set of time series of landmark signals at said set of landmark points from the captured time series of face images;
apply 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;
apply encoder processing to said set of processed landmark signals to generate a set of latent features; and
produce the first attention level indicator signal based on said set of latent features.
