Design and Application of Digital Twin‐Based Brain Control System
Bibliographic record
Abstract
Despite the development and application of brain‐computer interface (BCI) across various fields, this technology continues to face numerous challenges. The limitations in hardware and algorithm performance result in low recognition rates of BCI commands, hindering the system’s ability to perform efficiently and reliably, thus failing to meet the safety requirements. Digital twin (DT) technology, with its ultra‐high‐fidelity simulation and prediction capabilities, virtual–real interaction mapping, and autonomous feedback regulation, offers a novel approach to addressing these issues. Therefore, this paper proposes a DT‐based BCI (DT‐BCI) system framework, using a brain‐controlled vehicle as a case study to detail the roles and functions of each element within the framework. Meanwhile, the results of obstacle avoidance experiments show that the DT‐BCI system improves the task completion rate by 37.5% compared with the traditional brain–computer interface (T‐BCI), which proves that the DT technology has an important prospect for brain control applications, and lays the foundation for its wider application in complex operational scenarios.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
