Abstract

One example of a cutting-edge technology that is opening up new channels for human-machine connection is brain-computer interfaces, or BCIs. From keyboards and mice to touchscreens, voice commands, and gesture engagements, communication interfaces have evolved over time. New methods of controlling computer systems and engaging with virtual worlds have gained appeal as computers become more and more ingrained in daily life. These innovative applications range from gaming to teaching. It's important to handle ethical, privacy, and security issues related to developing and applying Brain-Computer Interface (BCI) technology from a balanced standpoint. Susceptible brain signals must be gathered and interpreted for BCI devices. Unauthorized access to this material carries the risk of compromising privacy by disclosing private thoughts, feelings, or other sensitive information. The initial areas of brain-computer interface (BCI) applications were based on EEG and created for medical use, hoping to help patients get back to their regular lives. Beyond the original purpose, EEG-based BCI applications have become more and more important in the non-medical field, helping healthy individuals live better lives by becoming more productive, collaborative, and self-developing, for example.
