With the advent of new technology, researchers attempt to ameliorate the shortages and limitations of the current BCI systems by taking advantage of cutting-edge technology, such as Augmented Reality (AR). In this way, the usage of BCI becomes quite auspicious not only for simple commands but also for high-level commands. By applying a high-technological application, the efficiency of BCI utilization was aimed to increase. To make it possible to use BCI technology in a surrounding area for the users, such as their home, the aim was to decrease errors during the experiments, and to make the studies more enjoyable for users, Augmented Reality (AR) and Virtual Reality (VR) were added to the system. For example, Takano et al. (2011) utilized Augmented Reality in their research to construct an intelligent environment that is an interactive space, in which users can communicate with their surrounding area via technological gadgets. It helps the target users to perform daily activities. Another study shows that an agent robot and electronics in robot’s environment controlled successfully by applying AR technology with the BMI (Kansaku, Hata and Takano, 2010). Research by Kerous and Liarokapis (2017) examined the communication between at least two people by using EEG-based BCI. Unity Game Engine (HTC Vive) was used to display P300 letter grid. Participants sent the messages letter by letter by using ERP-based speller to achieve BrainChat. Combining different technologies may allow us to control electronic devices in the smart spaces especially it will help people with disabilities.
