Cognitive and Neural Interfaces in Bridging Brain, Body, and Virtual Worlds
Abstract
The neural interface, coupled with wearable artificial intelligence (AI) and cognitive computing, is reshaping the way human beings interact with digital ecosystems, especially in immersive metaverse worlds. This chapter explains that cognitive and neural interfaces may be an epochal nexus among the human brain, physiological systems, and the virtual world. Wearable AI may be employed to decipher neural and biosignals continuously with the assistance of brain–computer interfaces, neuro-wearables, and sensor-laden body interfaces. These technologies are opening the way to adaptive, personalized, and context-sensitive health monitoring, which crosses the physical boundaries of previous years. The conversion of raw biosignals into actionable data in the metaverse, relying on AI-based analytics and the models of the digital twin, is instrumental in predicting diagnostics and providing biofeedback-based therapies. Specific attention is given to closed-loop systems in which neuroplasticity, rehabilitation outcomes, and human–machine symbiosis are fostered by the dynamic adjustment of virtual environments using neural feedback. Finally, the chapter deals with future problems and trends, such as ethics, data privacy, neural security, interoperability, and long-term user safety. This chapter discusses the possibility of a future wherein smart neural interfaces can readily augment human capabilities without triggering a breach of trust, transparency, and social welfare.
