Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If eye tracking technology is used for authentication and operation input, then diversity of input mechanisms is improved, but device complexity increases
Solution Approach 1:
The eye tracking system is designed to perform multiple functions including authentication verification and operation input control, allowing a single device to replace multiple input mechanisms such as keyboards, mice, and touch screens, thereby improving versatility while managing complexity through functional integration
Solution Approach 2:
The system introduces an eye tracking module as an intermediary component that captures eye movement data and translates it into authentication signals and operation commands, mediating between the user's natural eye movements and the digital interface without requiring direct manual interaction
2Ease of operation
If eye tracking procedure is implemented for authentication, then ease of operation is improved for individuals with mobility issues, but measurement precision requirements increase
Solution Approach 1:
The system performs preliminary calibration by capturing a face image sequence and verifying authentication before enabling eye tracking operations, establishing a baseline for accurate eye movement measurement and reducing the precision burden during actual operation by pre-validating the user's identity and setup
Solution Approach 2:
The system continuously monitors eye image sequences during the tracking procedure and provides feedback by comparing actual eye movements against expected patterns, adjusting measurement thresholds and validation criteria in real-time to maintain precision while accommodating natural variations in user behavior
3Reliability
If emergency mode detection is added to eye tracking procedure, then reliability is improved, but device complexity increases
Solution Approach 1:
The system incorporates preliminary emergency mode detection by monitoring eye movement patterns for signs of distress or abnormal behavior during the authentication and operation phases, preparing to trigger emergency protocols before critical situations develop, thereby improving reliability through proactive safety measures
Solution Approach 2:
The emergency mode detection functionality is merged with the existing eye tracking authentication system, using the same eye image sequence capture and analysis infrastructure to detect both authentication credentials and emergency conditions, thereby improving reliability without proportionally increasing device complexity through functional consolidation
Data Source
AI summary
A network authentication method and a system based on an eye tracking procedure are provided. An image capturing unit of a user terminal captures a face image sequence of a user, and transmits the face image sequence to a server terminal such that the server terminal executes an authentication procedure to return an authentication result. The user terminal executes an eye tracking procedure based an eye movement of the user. The user terminal transmits an emergency signal to the server terminal if the user terminal determines that an emergency mode is triggered during the eye tracking procedure.
