HCI is transformed by BCI interactions, breaking previous boundaries for the results to go directly into the device and creating a direct neuron-to-computer communication. The Work is centered on the improvement in HCI made possible by BCIs, notably greater simplicity and ease for those who have physical limitations. It calls into question present BCI systems, develops them into working interactive devices, tackles signal noise and user adaptability, and flagships future concepts such as neural decoding, AI, and ethical considerations. Neuroscience, AI, and user interface engineering together are design indicators for a smooth, cognition-enabling interactive era.
