Research Abstract

We have been studying the use of multiple channel elecroencephalogram (EEG) data to infer a human's thinking state. As a result, we have confirmed off-line thinking state estimation to be effective, in experimental studies on simulator training during malfunctions and mathematical problem solving. In this research, we reconsidered the mathematical model for thinking state estimation and concluded that an artificial neural network (ANN) model is more appropriate for real-time use than the linear regression model.
We developed a prototype real-time thinking state monitoring system with the ANN model and evaluated its classification accuracy via mathematical problem solving. The average rates of correct classification and misclassification were 68 % and 9 %, respectively. We used this model for reaHime monitoring and confirmed that the estimation result by the ANN model was found to coinckie with the subject's thinking state mode judged from the operator's behavior.
In order to develop an easier way of measurement, we examined the relationships between the thinking state and six physiological indices. As a result, we found that electrocardiogram (EGG) data, etectrooculogram (EOG) data, and respiratory curve (RSP) correlate to the thinking stata However, the best index W for each thinking state mode is different. We proposed a new estimation model with these three indices, which provided stably 60-70 % classification accuracy for day-to-day variations.
With emphasis on the practical use of thinking state monitoring, we applied a simple wireless electroencephalograph to monitor the operator's thinking state in a simulator training for emergency situations in a production plant. We expect that the monitoring result can be used to change the training menu in reference to the trainee's engagement level estimated from the thinking state information.
