Gaze-Based Login System for Hands-Free User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing login methods require users to initiate the process using input devices, which is impractical in scenarios lacking access to such devices, such as large screens viewed from a distance, environments with noise, or situations where hands are occupied, and do not address multi-user systems where users are not previously logged in.
Innovation Solution
A method that allows users to log into a computerized system by uninterruptedly staring at a display for a pre-defined duration, using imaging devices to detect and recognize specific individuals, enabling authentication without additional login information through facial, retinal, or iris recognition, or identification tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional login methods using input devices (keyboard, mouse, touch screen) are used, then user authentication can be performed, but the system becomes inaccessible to users who cannot operate input devices (handicapped users, drivers, passengers, or users in noisy environments)
Solution Approach 1:
The patent replaces mechanical input devices (keyboard, mouse, touch screen) with an optical detection system using imaging devices (cameras) to capture visual information of users' faces and eyes. This substitution eliminates the need for physical interaction, enabling users who cannot operate input devices to log in naturally by looking at the display.
Solution Approach 2:
The patent introduces an intermediary processing system that includes an imaging device to capture visual data, a processor to analyze the images for eye direction and facial recognition, and a display to provide feedback. This intermediary system bridges the gap between the user's natural behavior (looking at the screen) and the system's authentication requirement.
2Measurement precision
If visual input devices (facial recognition, retina recognition) are used for user identification, then authentication accuracy is improved, but these devices cannot initiate the login process by detecting user intent to log in
Solution Approach 1:
The patent performs preliminary detection of user intent by analyzing eye direction and gaze duration before initiating the authentication process. The system detects when a user is looking at the display for a predetermined period, which serves as a preliminary signal that the user wishes to log in, triggering subsequent facial recognition or other authentication methods.
Solution Approach 2:
The patent segments the login process into distinct phases: (1) intent detection phase using eye direction analysis, (2) user identification phase using facial recognition or other biometric methods, and (3) authentication phase. This segmentation allows each phase to be optimized independently, with eye tracking handling intent detection and facial recognition handling identification.
3Reliability
If the system requires users to actively indicate login intent using input devices, then security is maintained, but the system becomes unusable in scenarios where input devices are unavailable or inaccessible (large screens at distance, occupied hands, passenger seats)
Solution Approach 1:
The patent enables the system to automatically detect and initiate the login process without requiring user action with input devices. By monitoring eye direction and gaze duration, the system autonomously determines when a user intends to log in and triggers the authentication sequence, making the system self-activating and adaptable to various scenarios where input devices are unavailable.
