The development of a eustress sensing system using In-Ear EEG

It is necessary to remain in a eustress state while concentrating on a task to increase productivity. This study aimed to develop a eustress sensing system using In-Ear electroencephalograph (EEG). We demonstrated that EEG data measured by In-Ear EEG could be used to predict a subjective eustress state while performing eustress-inducing tasks.
