摘要：
There is a method and a system for concentration detection. The method for concentration detection includes the steps of extracting temporal features from brain signals； classifying the extracted temporal features using a classifier to give a score x1； extracting spectral-spatial features from brain signals； selecting spectral-spatial features containing discriminative information between concentration and non-concentration states from the set of extracted spectral-spatial features； classifying the selected spectral-spatial features using a classifier to give a score x2； combining the scores x1 and x2 to give a single score； and determining if the subject is in a concentration state based on the single score.
