| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Estimating the workload in the human brain can be useful for evaluating internal state. In this study, we used a wearable electroencephalography (EEG) system to estimate workload while participants walked in a naturalistic environment. We used auditory steady-state response (ASSR), that is, an oscillatory brain activity evoked by repetitive auditory stimuli, as the estimation index of workload. Participants performed three types of N-back tasks, which were expected to command different workloads, while walking at a constant speed. We found that the phase-locking index of ASSR activity was significantly correlated with the degree of task difficulty, even for EEG data from few electrodes. | |
