EEG-Based Brain-Computer Interfaces: A Thorough Literature Survey

TLDR

BCI technology aims to help disabled people communicate via brain signals, and EEG‑based BCI research has expanded rapidly in recent years. The study aimed to comprehensively summarize EEG‑based BCI research trends from 2007–2011 by examining publication counts, paradigms, aims, applications, features, classifiers, system types, and author nationalities. The authors conducted a systematic review of EEG‑based BCI articles from 2007–2011, extracting data on publication numbers, paradigms, aims, applications, features, classifiers, system types, and author nationalities. The survey presented detailed findings on each of these aspects, highlighting trends and gaps in EEG‑based BCI research. Supplementary tables are available online, and the study was funded by the National Research Foundation of Korea (grant 2012R1A2A2A03045395).

Abstract

Abstract Brain–computer interface (BCI) technology has been studied with the fundamental goal of helping disabled people communicate with the outside world using brain signals. In particular, a large body of research has been reported in the electroencephalography (EEG)-based BCI research field during recent years. To provide a thorough summary of recent research trends in EEG-based BCIs, the present study reviewed BCI research articles published from 2007 to 2011 and investigated (a) the number of published BCI articles, (b) BCI paradigms, (c) aims of the articles, (d) target applications, (e) feature types, (f) classification algorithms, (g) BCI system types, and (h) nationalities of the author. The detailed survey results are presented and discussed one by one. [Supplemental materials are available for this article.
