A classifier was trained to discriminate between three conditions: relaxed, low workload and high workload, using spectral features of the EEG. We obtained an average classification accuracy of 62%. A continuous workload index was obtained by low-pass filtering the classifier's output. The average correlation coefficient between the resulting workload index and the difficulty level of the task was 0.6. © 2011 Springer-Verlag.||Source Title:||Communications in Computer and Information Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/115406||ISBN:||9783642220944||ISSN:||18650929||DOI:||10.1007/978-3-642-22095-1_62|
