Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for displaying and analyzing EEG data lack effective methods for artifact removal, making it difficult for users to distinguish between original and cleaned signals, and to visualize the underlying brain activity.
Innovation Solution
A user interface and method for artifact removal in EEG data processing, utilizing a series of algorithmic filters to remove specific artifacts like eye blinks and muscle movements, with the ability to select and confirm applied filters, display original and filtered signals, and overlay processed reports on raw reports for clear visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If artifact removal filters are applied to EEG data, then the quality and accuracy of brain activity representation is improved, but the complexity of the system increases due to multiple filtering steps and processing stages
Solution Approach 1:
The artifact removal process is divided into multiple discrete filtering steps, each targeting specific types of artifacts (e.g., eye blinks, muscle movements). Users can selectively apply individual filters rather than a monolithic processing system, making the complexity manageable and customizable.
Solution Approach 2:
The system applies artifact removal filters in advance during the data processing stage, before final analysis and interpretation. This preliminary cleaning of EEG data ensures that subsequent analysis works with high-quality signals, improving measurement precision without adding complexity to the analysis phase.
2Reliability
If multiple filtering steps are used to remove artifacts, then the reliability of EEG analysis is improved, but the time required for processing increases
Solution Approach 1:
The filtering process is made dynamic and adaptive, allowing the system to adjust the number and type of filters applied based on the specific characteristics of the EEG recording. This ensures reliable artifact removal while minimizing unnecessary processing time for recordings with minimal artifacts.
Solution Approach 2:
The system includes automated detection capabilities that identify the presence and type of artifacts in EEG data, then automatically applies appropriate filters without requiring extensive manual intervention. This self-service approach maintains high reliability while reducing the time investment required from users.
3Ease of operation
If original and filtered signals are displayed together, then the ease of operation is improved by allowing user confirmation, but the device complexity increases due to overlay display requirements
Solution Approach 1:
The system displays original and filtered EEG signals in the same visual space using different visual dimensions - such as different colors, line styles, or transparency levels - to distinguish between them. This allows users to easily compare and confirm filter effects without requiring separate display areas, maintaining ease of operation while managing display complexity.
