Gaze-Based Security Display Masking Eye Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display screens lack privacy, as information displayed is visible to anyone nearby, potentially compromising sensitive information, especially in public areas where 'looking-over-the-shoulder' is a concern.
Innovation Solution
A gaze-based security system that uses eye-tracking data to determine the movement status of a user's eye, adjusting the display configuration to mask information when the eye is in motion and unmask it when stationary, ensuring only the intended user can view sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is displayed on a monitor screen, then the information is viewable by anyone looking at the screen, but the privacy of such information is jeopardized if a passerby or other people located in proximity to the user looks at the screen
Solution Approach 1:
The display dynamically adjusts its content based on real-time eye movement detection. When the system detects that the user's eye is moving (indicating someone else is looking at the screen), it automatically masks the displayed information. When the eye is stationary (indicating the user is viewing the screen), the information is displayed normally. This dynamic adaptation resolves the contradiction by making the display both viewable and private depending on the viewing context.
Solution Approach 2:
The system uses eye-tracking technology to continuously monitor the user's eye movement and provides feedback to the display system. Based on this feedback, the display automatically adjusts whether to show masked or unmasked information. This closed-loop feedback mechanism ensures that privacy protection is activated only when needed, maintaining ease of operation for the legitimate user while preventing privacy compromise for passersby.
2Object-affected harmful factors
If masking data is displayed when the eye is in motion, then privacy is protected, but the user cannot view the actual data during eye movement
Solution Approach 1:
The display switches between masked and unmasked states based on real-time detection of eye movement. During normal viewing (stationary eye), the actual data is accessible. When eye movement is detected (indicating the user is looking away), the display dynamically masks the data to protect privacy. This dynamic state change ensures that data accessibility is maintained during legitimate use while privacy is protected when the user is not viewing the screen.
3Object-affected harmful factors
If eye-tracking technology is used to determine movement status, then privacy protection is enabled, but device complexity increases
Solution Approach 1:
The eye-tracking technology serves multiple functions: it detects user presence, determines viewing intent, and triggers privacy protection mechanisms. By making the eye-tracking system multi-functional, the patent reduces the need for separate complex systems for each function, thereby limiting the increase in overall device complexity while maintaining strong privacy protection capabilities.
Data Source
AI summary
Systems and methods for presenting actual data on a display device based on eye-tracking data. An eye-tracking engine receives sensed data from an eye-tracking device, determines a movement status of an eye based on the sensed data, and determines a display configuration based on the determined movement status. The display configuration is output on the display device and includes masking data when the determined movement status indicates the eye is in motion.
