A method of determining data model for use in predicting a state of a user based on collected biometric data collected via a sensor platform, the method comprising receiving from sensors of the sensor platform a plurality of the biometric data； extracting a plurality of representative features from the plurality of biometric data； receiving a plurality of user affect parameters associated with the plurality of representative features； correlating the plurality of user affect parameters with the plurality of representative features to determine a set of representative feature-affect pairings for the data model as a plurality of model data parameters； and storing the data model for subsequent use in determining the real time state of the user.
