This study compares the performance of two EEG devices, a low-cost brain\u2013computer interface (BCI) (Emotiv EPOC+) and a high-end EEG (BrainVision), for the detection of four emotional conditions over 20 participants. For that purpose, signals were acquired with both devices under the same experimental procedure, and a comparison was made under three different scenarios, according to the number of channels selected and the sampling frequency of the signals analyzed. A total of 16 statistical, spectral and entropy features were extracted from the EEG recordings. A statistical analysis revealed a major number of statistically significant features for the high-end EEG than the BCI device under the three comparative scenarios. In addition, different machine learning algorithms were used for evaluating the classification performance of the features extracted from high-end EEG and low-cost BCI in each scenario. Artificial neural networks reported the best performance for both devices with an F[Formula: see text]-score of 75.08% for BCI and 98.78% for EEG. Although the professional EEG outcomes were higher than the low-cost BCI ones, both devices demonstrated a notable performance for the classification of the four emotional conditions. <\/jats:p>","DOI":"10.1142\/s0129065722500411","type":"journal-article","created":{"date-parts":[[2022,6,24]],"date-time":"2022-06-24T08:31:27Z","timestamp":1656059487000},"source":"Crossref","is-referenced-by-count":17,"title":["Emotion Classification from EEG with a Low-Cost BCI Versus a High-End Equipment"],"prefix":"10.1142","volume":"32","author":[{"given":"Roberto","family":"S\u00e1nchez-Reolid","sequence":"first","affiliation":[{"name":"Departamento de Sistemas Inform\u00e1ticos, Universidad de Castilla-La Mancha, Albacete, 02071, Spain"},{"name":"Instituto de Investigaci\u00f3n en Inform\u00e1tica de Albacete, Albacete 02071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Cruz","family":"Mart\u00ednez-S\u00e1ez","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda, Universidad de Castilla-La Mancha, Albacete 02071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz","family":"Garc\u00eda-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Departamento de Sistemas Inform\u00e1ticos, Universidad de Castilla-La Mancha, Albacete, 02071, Spain"},{"name":"Instituto de Investigaci\u00f3n en Inform\u00e1tica de Albacete, Albacete 02071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luz","family":"Fern\u00e1ndez-Aguilar","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda, Universidad de Castilla-La Mancha, Albacete 02071, Spain"},{"name":"Neurological Disabilities Research, Institute, Albacete, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Ros","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda, Universidad de Castilla-La Mancha, Albacete 02071, Spain"},{"name":"Neurological Disabilities Research, Institute, Albacete, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Miguel","family":"Latorre","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda, Universidad de Castilla-La Mancha, Albacete 02071, Spain"},{"name":"Neurological Disabilities Research, Institute, Albacete, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Fern\u00e1ndez-Caballero","sequence":"additional","affiliation":[{"name":"Departamento de Sistemas Inform\u00e1ticos, Universidad de Castilla-La Mancha, Albacete, 02071, Spain"},{"name":"Instituto de Investigaci\u00f3n en Inform\u00e1tica de Albacete, Albacete 02071, Spain"},{"name":"CIBERSAM (Biomedical Research Networking, Centre in Mental Health), Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"key":"S0129065722500411BIB001","doi-asserted-by":"publisher","DOI":"10.1007\/BF00992553"},{"key":"S0129065722500411BIB002","doi-asserted-by":"publisher","DOI":"10.1177\/1754073910374661"},{"key":"S0129065722500411BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-13105-4_46"},{"key":"S0129065722500411BIB004","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065720500318"},{"key":"S0129065722500411BIB005","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065720500136"},{"key":"S0129065722500411BIB006","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065721500131"},{"key":"S0129065722500411BIB007","doi-asserted-by":"publisher","DOI":"10.1007\/s10916-020-01639-x"},{"key":"S0129065722500411BIB008","doi-asserted-by":"publisher","DOI":"10.1037\/h0077714"},{"key":"S0129065722500411BIB009","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065718500387"},{"key":"S0129065722500411BIB010","doi-asserted-by":"publisher","DOI":"10.3389\/fninf.2019.00040"},{"key":"S0129065722500411BIB011","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065720500215"},{"key":"S0129065722500411BIB012","doi-asserted-by":"publisher","DOI":"10.1007\/s12559-020-09789-3"},{"key":"S0129065722500411BIB013","doi-asserted-by":"publisher","DOI":"10.1109\/TAFFC.2018.2890636"},{"key":"S0129065722500411BIB014","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbr.2015.10.036"},{"key":"S0129065722500411BIB015","doi-asserted-by":"publisher","DOI":"10.1515\/revneuro-2015-0025"},{"key":"S0129065722500411BIB017","doi-asserted-by":"publisher","DOI":"10.1109\/CarpathianCC.2014.6843587"},{"key":"S0129065722500411BIB019","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-20816-9_58"},{"key":"S0129065722500411BIB020","first-page":"5384","volume-title":"2005 IEEE Engineering in Medicine and Biology 27th Annual Conf.","author":"Piccini L.","year":"2006"},{"key":"S0129065722500411BIB021","first-page":"913","volume-title":"2018 Federated Conf.
