1. An emotion recognition system for automatically assessing human emotional behavior from physical phenomena indicative of the human emotional behavior, the system comprising: one or more a sensors configured to sense, the physical phenomena; and a computer processing system configured to: receive a time series of signals from the one or more sensors; identify features, in the time series of signals that are indicative of the human emotional behavior; and output a gradient, multiple-perspective assessment of the human, emotional behavior based on the identified features that includes a gradient representation of each of multiple emotional states indicated by the human emotional behavior.

The system of claim 1 , wherein the features comprise one or more of time domain features and transform domain features; wherein the time domain features comprise one or more of amplitudes of the SIGNALS; derivatives of the amplitudes; energy contours of the signals; and intensity contours of the signals; and wherein the transform domain features comprise one or more of: spectral, domain features of the signals; time-frequency transforms of the signals; variants of the time-frequency transforms; and derivatives of the spectral domain features, wherein the derivatives of the spectral domain features comprise one or more of: pitch; formants; and filterbank energies.
