Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If human involvement is increased for labeling training data, then classification accuracy is improved, but cost and time consumption increase
Solution Approach 1:
The system uses passive EEG measurements to automatically capture human cognitive processing information without requiring active participation or conscious effort from users. The brain's natural electrical activity is measured while users simply view images, eliminating the need for manual labeling while still obtaining valuable human processing data for improving classification accuracy
Solution Approach 2:
EEG technology serves as an intermediary that bridges human cognitive processing and computer vision systems. The EEG device captures subconscious brain responses to images and translates them into usable data that can be integrated with computer vision algorithms, allowing human expertise to be leveraged without direct human intervention in the labeling process
2Measurement precision
If human involvement is increased for labeling training data, then classification accuracy is improved, but cost increases
Solution Approach 1:
The system automatically collects human cognitive data through passive EEG measurements during natural image viewing, eliminating the need to pay humans for manual labeling work. The brain's own electrical activity provides the labeling information free of charge, removing the human cost associated with traditional labeling approaches
Solution Approach 2:
Instead of directly using human-labeled data, the system creates a copy or representation of human cognitive processing through EEG signals. These electrical patterns serve as proxies for human visual processing, allowing the system to leverage human expertise indirectly through measurable brain activity rather than expensive manual annotation
3Measurement precision
If active participation from users is required, then labeling quality is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of requiring users to actively perform labeling tasks, the system inverts the approach by passively measuring users' natural brain responses while they simply view images. The labeling information is extracted from unconscious cognitive processing rather than conscious effort, making the operation extremely easy while maintaining high quality
Solution Approach 2:
The system leverages the brain's natural, automatic cognitive processing of visual information. Users don't need to learn or perform any special tasks; their brains naturally process the images and generate measurable EEG signals that serve as the labeling data, requiring zero training or active participation
4Productivity
If computer vision-based processing is used, then productivity is improved, but classification accuracy deteriorates
Solution Approach 1:
The system merges computer vision processing with human cognitive processing by integrating EEG measurements with image analysis algorithms. This combination allows the system to maintain the high productivity of automated computer vision while incorporating the superior classification accuracy of human visual processing, achieving both speed and precision
Solution Approach 2:
The system creates a composite information processing approach by combining data from two different sources: computer vision feature extraction and human brain electrical activity patterns. This composite methodology leverages the strengths of both automated processing and human cognition to achieve high accuracy without sacrificing productivity
