EEG_data_with_labels.mat

We took EEG samples of 3 seconds length before each vehicle deviation event. The dimensions of each sample are 30 (channels) × 1500 (sampling points). The local response time (RT) refers to the response time of the participants to the vehicle deviation event, and the global response time (global-RT) refers to the average response time in the 90 seconds prior to the event. The baseline "alert response time" for each session was defined as the 5th percentile of local response time. Samples with both local reaction time and global reaction time less than 1.5 times alert response time were labeled as alert, while samples with both local reaction time and global reaction time longer than 2.5 times alert response time were labeled as drowsy.
