Expanding the Frontiers of Wearable Brain-Computer Interfaces Combining Augmented Reality and Visually Evoked Potentials

Given the increasing demand for systems that enable seamless human-computer interaction, this study presents the design and implementation of a highly wearable Brain-Computer Interface (BCI). The proposed BCI leverages Augmented Reality (AR) technology to elicit users' Steady-State Visually Evoked Potential (SSVEP) in a more immersive manner compared to traditional state-of-the-art setups. Additionally, the employment of a portable, wireless EEG acquisition system represents a significant enhancement in terms of system wearability, thereby facilitating the adoption of BCI technology also in everyday contexts.
