Gaze-Tracking Calibration Through Access Authorization Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaze-tracking systems lack a method to contemporaneously calibrate themselves and authorize access to other systems, particularly in applications where iris recognition is not feasible.
Innovation Solution
A system comprising a processor and memory that stores modules for preliminary operations, authorization, and gaze-tracking, allowing for the comparison of a gaze trajectory with a calibration pattern to simultaneously calibrate the gaze-tracking system and authorize access to another system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gaze-tracking system performs separate calibration and authorization processes, then the system can be calibrated and authorized, but the process requires multiple separate steps and more time
Solution Approach 1:
The patent combines the gaze-tracking calibration process and the authorization process into a single unified operation. The system uses the same gaze trajectory data for both calibrating the gaze-tracking system and verifying user authorization, eliminating the need for separate calibration and authorization steps. This merging of processes directly addresses the technical contradiction by improving productivity while reducing the time required.
Solution Approach 2:
The gaze trajectory pattern serves multiple functions simultaneously: it acts as both a calibration reference pattern for the gaze-tracking system and an authorization verification pattern for the first other system. This multi-functionality allows a single data collection process to achieve both calibration and authorization objectives, resolving the contradiction between efficiency and time consumption.
2Reliability
If iris recognition is used for authorization, then security can be enhanced, but the system cannot be used when iris recognition is not feasible
Solution Approach 1:
The patent changes the biometric parameter from iris recognition to gaze trajectory analysis. Instead of relying on iris patterns, the system uses the dynamic movement pattern of the gaze point across the display. This parameter change maintains the security and reliability of biometric authorization while significantly improving adaptability, allowing the system to work in situations where iris recognition is not feasible.
Solution Approach 2:
The patent substitutes the optical-based iris recognition system with a gaze-tracking based authorization system. By replacing the iris recognition mechanism with gaze trajectory analysis, the system achieves comparable security through a different technical approach that is more versatile and can be applied in broader contexts where iris recognition may not be possible.
3Measurement precision
If a gaze-tracking system is calibrated separately before use, then the system can be calibrated, but additional time and steps are required before the system can be used for its intended purpose
Solution Approach 1:
The patent merges the calibration process with the initial system access process. Instead of requiring a separate calibration session before the system can be used, the calibration is performed as part of the authorization process. The user's gaze trajectory is captured during the authorization attempt, and this same data is used to calibrate the gaze-tracking system, thereby improving ease of operation without compromising measurement precision.
Solution Approach 2:
The system performs calibration as a preliminary action during the authorization process itself. By capturing the gaze trajectory pattern during the authorization attempt and using it for both calibration and verification purposes, the system eliminates the need for a separate post-calibration step before the system becomes operational.

AI summary
A system for contemporaneously calibrating a gaze-tracking system and authorizing access to a first other system can include a processor and a memory. The memory can store a preliminary operations module, an authorization module, and a gaze-tracking module. The preliminary operations module can include instructions to compare a trajectory, of a point of gaze of an eye, with a pattern associated both with a calibration of the gaze-tracking system and with a first authorization process, that excludes an iris recognition process, for the first other system. The authorization module can include instructions to cause an access to the first other system to be authorized. The gaze-tracking module can include instructions to: (1) cause the gaze-tracking system to be calibrated and (2) cause, in response to the gaze-tracking system being calibrated, the gaze-tracking system to be configured to be a user interface for a second other system.
