Engineering Contradiction Analysis
1Quantity of substance
If eye tracking data is collected across multiple devices and platforms, then the quantity and diversity of data increases, but the complexity of data processing and analysis increases
Solution Approach 1:
The system segments the data processing workflow into distinct modules: data collection from multiple devices, data transmission to server, data storage in database, and data analysis/visualization. Each module handles specific aspects of the data pipeline independently, reducing overall system complexity while enabling comprehensive multi-device data collection.
Solution Approach 2:
The patent introduces intermediary components including a server that mediates between client devices and the database, and uses standardized data formats as intermediaries for data exchange. This intermediary layer abstracts the complexity of multi-device data integration, allowing diverse devices to contribute data without directly complicating the analysis system.
2Loss of information
If comprehensive eye tracking analysis is performed across multiple devices, then the depth of insights into user behavior increases, but the time and computational resources required increase
Solution Approach 1:
The system performs preliminary data processing and validation at the collection stage, organizing raw eye tracking data into standardized formats before transmission to the server. This preliminary action reduces the computational burden during subsequent analysis phases, enabling deeper insights without proportional increases in analysis time.
Solution Approach 2:
The patent employs automated computational algorithms and machine learning models to replace manual data analysis methods. This substitution enables comprehensive processing of large volumes of eye tracking data from multiple devices, extracting deep user behavior insights efficiently without requiring extensive manual time investment.
3Reliability
If eye tracking data is stored and processed on a centralized server, then data security and management control improve, but network dependency and transmission delays increase
Solution Approach 1:
The system implements local data buffering and preprocessing capabilities at client devices, allowing data to be captured and initially processed locally before transmission. This local quality enhancement reduces network dependency for basic operations while maintaining centralized server control for security and management, thereby reducing transmission delays for critical functions.
