The system analyzes how an individual user’s brain response varies with the parameters of a controlled stimulus. It then creates an individualized tuning map and automatically selects the most stable, repeatable and informative combinations of stimulus parameters and signal features for one or more BCI decoders.
The application covers a method, system, computer program and computer-readable medium for the parametric calibration of brain–computer interfaces.
The technology is intended for companies and teams developing EEG/BCI systems in which calibration time, inter-user variability, feature instability or between-session drift limit reliability and practical deployment.
The system presents stimuli with controlled parameters, records the brain response and creates an individualized tuning map. Based on this map, it selects the most stable and informative combinations of stimulus parameters and signal features for use by one or more BCI decoders.
The system varies selected parameters of the presented stimulus.
Signals reflecting the user’s brain response are recorded simultaneously.
Response measures are derived from signal features and linked to stimulus parameters.
An individualized map of stimulus parameters and signal features is created.
Combinations with the highest stability and information value are selected.
Calibration in many BCI systems is designed for a specific set of stimuli, signal features and a particular decoder. Fixed settings do not fully account for differences between users or changes across sessions, often requiring repeated calibration and producing features that may be unstable or weakly informative.
The solution separates brain-response mapping from final decoding. The system first creates an individualized map of how the user’s response depends on stimulus parameters and then automatically selects combinations of parameters and signal features with the highest stability, repeatability and information value.
