1. A method for estimating cognitive efficacy of an individual, comprising the steps of:
- collecting electroencephalogram (EEG) data from EEG sensors coupled to the individual, while the individual is performing a plurality of tasks;
supplying the EEG data to a trained classifier that generates an estimate of cognitive effort of the individual for each of the plurality of tasks performed by the individual;
generating baseline cognitive effort data for the individual, based on the plurality of tasks; and
comparing the estimates of cognitive effort to the baseline cognitive effort data to determine a change in cognitive efficacy of the individual.

Abstract
A system and method for estimating cognitive efficacy of an individual is provided. The individual is subjected to a plurality of tasks. Electroencephalogram (EEG) data from EEG sensors coupled to the individual are collected while the individual is performing the plurality of tasks. The EEG data are supplied to a trained classifier that generates an estimate of cognitive effort of the individual for each of the plurality of tasks performed by the individual.

10. A system for estimating cognitive efficacy of an individual performing a plurality of tasks, the system comprising:
-
a plurality of EEG sensors adapted to be coupled to the individual, each EEG sensor configured to collect EEG data from the individual, while the individual is performing the plurality of tasks, and supply the collected EEG data; memory having baseline cognitive effort data for the individual stored therein, the baseline cognitive effort data based on the plurality of tasks; and a processor in operable communication with the memory and coupled to receive the collected EEG data and configured, upon receipt of the EEG data, to (i) generate an estimate of cognitive effort of the individual for each of the plurality of tasks performed by the individual, (ii) selectively retrieve the baseline cognitive effort data from the memory, and (iii) compare the estimate of cognitive effort to the baseline cognitive effort data to determine a change in cognitive efficacy of the individual. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for estimating cognitive efficacy of an individual performing a plurality of tasks, the system comprising:
-
a plurality of EEG sensors adapted to be coupled to the individual, each EEG sensor configured to collect EEG data from the individual, while the individual is performing the plurality of tasks, and supply the collected EEG data; memory having baseline cognitive effort data for the individual stored therein, the baseline cognitive effort data based on the plurality of tasks; and a processor configured to implement a trained classifier, the processor in operable communication with the memory and coupled to receive the collected EEG data and further configured, upon receipt of the EEG data, to; generate an estimate of cognitive effort of the individual for each of the plurality of tasks performed by the individual, selectively retrieve the baseline cognitive effort data from the memory, compare the estimate of cognitive effort to the baseline cognitive effort data to determine a change in cognitive efficacy of the individual, and compare updated estimates of cognitive effort to the baseline cognitive effort data to track changes in the cognitive efficacy of the individual. - View Dependent Claims (19, 20)
