Abstract
A method for training a system for measuring or estimating or both of a user's response to a stimulus and for classifying the response is disclosed. The system is trained using a test stimulus presented to one or more users. One or more images of the users' face are captured and simultaneously EEG signals of the users are captured. One or more emotional features are derived from the facial data of the users. One or more cognitive features and emotional features are derived from the EEG signals of each of the users, and a training dataset is created by correlating the one or more emotional features from the facial data, one or more cognitive and emotional features from the EEG signals with one or more features associated with the test stimulus. Created training dataset is used for measuring or estimating or both of a user's response to the stimulus.
