Its contributions in medical fields range from prevention to neuronal rehabil- itation for serious injuries. Mind reading and remote communication have their unique fingerprint in numerous fields such as educational, self-regulation, production, marketing, security as well as games and entertainment. It creates a mutual understanding between users and the surrounding sys- tems. This paper shows the application areas that could benefit from brain waves in facilitating or achieving their goals. We also discuss major usability and technical challenges that face brain sig- nals utilization in various components of BCI system. Different solutions that aim to limit and decrease their effects have also been reviewed. - 2015 Production and hosting by Elsevier B.V. on behalf of Faculty of Computers and Information,en-USOctober University for university of Brain Computer Interfaces;Brain signal acquisition;BCI applications;Mind commands;Brain monitoringBCI challengesArticlehttps://doi.org/10.1016/j.eij.2015.06.002
