摘要：
A device and method for generating a representation of a subject's attention level. The device measures brain signals from the subject； extracts temporal features from the brain signals； classifies the extracted temporal features using a classifier to give a score X1； extracts spectral-spatial features from the brain signals； selects spectral-spatial features containing discriminative information between concentration and non-concentration states from the set of extracted spectral-spatial features； classifies the selected spectral-spatial features using a classifier to give a score X2； combines the scores X1 and X2 to give a single score； and presents the score to the subject.
