Engineering Contradiction Analysis
1Measurement precision
If traditional gaze demarcating methods are used, then the demarcating process is simple, but the accuracy of gaze calculation and gesture position recognition is poor
Solution Approach 1:
The system performs preliminary calibration by collecting pupil coordinates and gesture position coordinates before actual interaction. This pre-collection of data establishes a baseline mapping relationship that improves subsequent gaze calculation accuracy without adding complexity during the interaction phase.
Solution Approach 2:
The system uses gesture position coordinates as feedback to refine and update the gaze mapping model during interaction. By continuously comparing predicted gaze positions with actual gesture positions, the system adjusts the mapping parameters to improve accuracy dynamically.
2Reliability
If complex demarcating processes are implemented to improve accuracy, then the risk of demarcating failure increases, but the accuracy of eye movement tracking improves
Solution Approach 1:
The system performs preliminary calibration to establish the gaze mapping model before actual use, ensuring the demarcating process is ready and validated in advance. This reduces the risk of failure during actual interaction while maintaining high accuracy through pre-optimized parameters.
Solution Approach 2:
The system dynamically adjusts mapping parameters based on collected data, optimizing the gaze calculation model for different users and conditions. This adaptive parameter adjustment maintains high reliability across varying scenarios while preserving measurement precision.
3Measurement precision
If more data points are collected for gaze demarcating, then the accuracy improves, but the time required for demarcating increases
Solution Approach 1:
The system collects and processes demarcating data in advance during a calibration phase, so that during actual interaction, the pre-established mapping model can be applied immediately without requiring extensive real-time data collection, thus reducing time loss.
Solution Approach 2:
The system collects a sufficient number of data points during calibration to achieve accurate demarcating, then uses this pre-collected data for subsequent operations. This partial action during calibration avoids the need for continuous excessive data collection during interaction, balancing accuracy with time efficiency.
