Simulating the Real World Through Bi-Directional Brain-Computer Interfaces: A Conceptual Framework

TechRxiv

“This paper introduces a conceptual framework for simulating the real world using bi-directional brain-computer interfaces (BCIs). By integrating advanced neuroscience, artificial intelligence, and virtual reality technologies, we propose a system that can create immersive, interactive environments indistinguishable from reality. The framework addresses key challenges in BCI technology, including signal processing, neural decoding, and sensory feedback, while exploring the ethical and societal implications of such advanced simulation capabilities.”
