Solution Overview
Problem
Current applications of EEG data are primarily limited to medical and research purposes, with limited use in artistic or creative representations of individual or collective brain states, lacking effective methods to visualize and interpret synchronicity or coherence of spectral characteristics between individuals or groups.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EEG data is processed to isolate spectral characteristics and convert them into visual, auditory, and tactile components, then the artistic and creative representation of brain states is improved, but the device complexity increases
Solution Approach 1:
The system converts isolated spectral characteristics into multiple types of outputs (visual, auditory, and tactile components) using a single processing framework. The translation parameters map spectral features to diverse sensory modalities, allowing one system to serve multiple representation purposes simultaneously, thereby improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The system applies predefined translation parameters that transform spectral characteristics into different output formats. By changing the parameter set used for translation, the same processed EEG data can generate different types of artistic representations (visual, auditory, tactile) without requiring separate processing pipelines for each modality.
2Quantity of substance
If multiple spectral characteristics are combined to form group averages, then the collective summary of brainwaves is improved, but the loss of individual neural detail increases
Solution Approach 1:
The system segments the spectral characteristics into distinct components (e.g., alpha, beta, theta, delta, gamma waves) and processes them separately before combining. This allows the collective summary to be formed from standardized spectral segments while preserving the ability to reference individual neural details through the segmented components, reducing information loss.
Solution Approach 2:
The isolated spectral characteristics serve as an intermediary layer between the raw EEG data and the collective summary. This intermediary preserves the essential spectral information needed for group averages while maintaining a structured representation that can reference individual neural patterns, thus reducing the loss of individual detail.
3Speed
If real-time processing of EEG data is implemented, then the dynamic visualization of brain activity is improved, but the computational resource consumption increases
Solution Approach 1:
The system performs preliminary signal processing steps (filtering, FFT transformation) to isolate spectral characteristics before the real-time visualization. By completing these computationally intensive tasks in advance or in parallel, the real-time rendering of brain activity visualizations can proceed more efficiently with reduced computational resource consumption.

Implementation Method 1
the raw EEG from each channel may be run through a fast Fourier transform (FFT) to separate out various frequency components in each channel
Implementation Method 2
the EEG data may be run through a high and low bandpass filter prior to the filtered data being run through the FFT to isolate the spectral frequencies of each channel
Data Source
AI summary
Systems and methods for providing a computer-generated visualization of EEG data are disclosed. Raw EEG data generated from a multi-channel EEG headset (or other device) may be received. The EEG data may be run through a fast Fourier transform (FFT) to separate out various frequency components in each channel, isolating the brain wave components for each channel. A visual display may be generated based on the isolated components comprising a first display portion and a second display portion. The first display portion may comprise a geometrical mesh with predefined parameters representing the portions of a crystal. The second display portion may comprise a time-varying color visualization based on the variance of the brain waves. A composite computer display in which the first display portion is overlaid over the second display portion may be generated and provided via a display device.
