Gaze Tracking Authentication Pattern for Headset Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enhanced reality systems require users to repeatedly remove and reattach headsets for authentication, which is cumbersome and increases login friction, and there is a need for improved security and calibration methods to enhance data access.
Innovation Solution
A gaze-tracking system that integrates authentication and calibration by defining a unique eye movement authentication pattern, allowing users to authenticate and calibrate the system simultaneously without removing the headset, using a display device and gaze tracking system to capture eye movements and a controller to verify the pattern and calibrate the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users authenticate by removing and reattaching headsets, then security is improved through physical verification, but ease of operation deteriorates due to repeated manual actions and login friction
Solution Approach 1:
The patent replaces the mechanical action of removing and reattaching headsets with an optical/gaze-based authentication system. The eye-tracking system detects and analyzes user gaze patterns to verify identity, substituting physical mechanical verification with optical field-based detection, thereby maintaining security while eliminating the cumbersome manual operations.
Solution Approach 2:
The system enables automatic authentication by having the user simply look at the display without requiring manual actions. The gaze tracking system automatically captures eye movement data, processes it through pattern recognition algorithms, and completes authentication autonomously, allowing the system to serve itself in verifying user identity without requiring the user to perform complex manual steps.
2Measurement precision
If separate authentication and calibration processes are used, then measurement precision is improved through dedicated calibration steps, but loss of time increases due to multiple sequential operations
Solution Approach 1:
The patent merges the authentication process with the calibration process into a single integrated operation. During authentication, the same gaze tracking data that verifies user identity is simultaneously used to calibrate the eye-tracking system for that user. This consolidation eliminates the need for separate calibration steps, reducing time loss while maintaining measurement precision through the dual-purpose data collection.
Solution Approach 2:
The gaze tracking system is designed to perform multiple functions simultaneously: it authenticates user identity through pattern recognition while also calibrating itself for accurate future measurements. This multi-functional approach allows a single data collection phase to serve both authentication and calibration purposes, maximizing system utility while minimizing the time required.
3Reliability
If complex authentication patterns are required, then security is improved through更难 replication, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The system enhances security by analyzing multiple parameters of eye movement simultaneously, including gaze duration, movement velocity, acceleration patterns, and fixation points. By monitoring changes across these multiple parameters rather than relying on a single metric, the system creates a comprehensive biometric profile that is difficult to replicate, thereby improving security without requiring additional hardware sensors.
Solution Approach 2:
The system creates a digital copy or model of the user's unique eye movement patterns during calibration, storing this biometric template for future authentication. This copied pattern serves as the security credential, allowing the system to verify identity by comparing live gaze data against the stored template, thereby achieving high security through software-based pattern recognition rather than complex hardware mechanisms.
