5.) Current Technology and Future Scope of EEG-Based Devices
Although there are various ready-to-use brain-controlled devices and games available in the market, several companies also provide options for engineers to design a customised brain-controlled device. While some companies provide wearable EEG headgear, others have also released their own software kits that help with the pre-processing of the signals and the development of classification algorithms. That being said, the current technology pertaining to the decoding of EEG signals is still quite limited and is restricted to simpler or specific problems.

There is still a lot to be explored when it comes to the analysis of EEG signals because human beings are far from understanding every fluctuation or spike that appears on an electroencephalogram. However, the ongoing research in the field of brain-controlled devices and the interpretation of human thoughts from EEG signals is a step in the positive direction, which may lead to the development of a technology that can fully harness the information encoded in the EEG signals.
