Open EEG Datasets for Passive Brain-Computer Interface Applications: Lacks and Perspectives

With the advent of open science, a growing number of researchers have been sharing their datasets and processing methods. Yet not all fields are concerned and some still lack open databases which would enable faster, more relevant research, and more importantly favour replicability and reproducibility of results. This is particularly true for the field of brain-computer interfaces, and most especially for that of the relatively new field of passive brain-computer interfaces. This article provides an overview of the currently available datasets for passive brain-computer interface applications based on electroencephalography. Their main characteristics are detailed, including the number of participants, tasks, electrode setups and electrode location information. Lacks are highlighted and discussed, and recommendations are given for future studies.
