Solution Overview
Problem
Current brain-computer interface (BCI) training methods are difficult to learn and require significant effort for users to control their brainwaves effectively, limiting the adoption and usage of BCIs.
Innovation Solution
A system and method that combines bio-signal and non-bio-signal data collection and analysis to improve the training process, using machine learning algorithms to analyze and share data in real-time, enabling more accurate and responsive performance of BCI applications by identifying user brain states and adapting to individual interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional BCI training methods are used, then users can learn to control their brainwaves, but the learning curve is steep and training is difficult
Solution Approach 1:
The system performs preliminary classification of brain states using machine learning algorithms before BCI control is fully established. By pre-analyzing EEG data to identify cognitive and emotional states, the system prepares control commands in advance, reducing the time users need to spend learning manual brainwave control techniques.
Solution Approach 2:
The patent introduces an intermediary classification system that acts as a mediator between raw brainwaves and BCI control. The machine learning classifier serves as an intermediate layer that automatically interprets brain states and translates them into control commands, eliminating the need for users to directly control their brainwaves through difficult training.
2Measurement precision
If only bio-signal data (EEG) is collected, then the system can measure brainwave patterns, but the analysis accuracy is limited without contextual information
Solution Approach 1:
The system merges bio-signal data (EEG) with non-bio-signal data (environmental context, device interactions, user profiles) into a unified analysis framework. By combining these diverse data sources, the system achieves more accurate brain state detection while managing complexity through integrated data processing pipelines.
Solution Approach 2:
The patent creates a multi-functional data collection system that simultaneously gathers EEG data, environmental sensors data, device interaction data, and user profile information. This universal data collection approach serves multiple functions: improving classification accuracy, providing contextual information, and enabling personalized BCI control, all within a single system architecture.

AI summary
A computer network implemented system for improving the operation of one or more biofeedback computer systems is provided. The system includes an intelligent bio-signal processing system that is operable to: capture bio-signal data and in addition optionally non-bio-signal data; and analyze the bio-signal data and non-bio-signal data, if any, so as to: extract one or more features related to at least one individual interacting with the biofeedback computer system; classify the individual based on the features by establishing one or more brain wave interaction profiles for the individual for improving the interaction of the individual with the one or more biofeedback computer systems, and initiate the storage of the brain waive interaction profiles to a database; and access one or more machine learning components or processes for further improving the interaction of the individual with the one or more biofeedback computer systems by updating automatically the brain wave interaction profiles based on detecting one or more defined interactions between the individual and the one or more of the biofeedback computer systems. A number of additional system and computer implemented method features are also provided.
