Fig. 5: Characteristics of an ideal BCI system for communication its achieving solutions.
From: Progress, challenges and future of linguistic neural decoding with deep learning

The BCI system requires high-quality brain recordings and addresses the problem of individual and time differences through strategies such as domain alignment. Additionally, the reform of network structure, especially the application of LLM, provides ideas for high-precision, low-latency, and multi-functional interactions.
