Iris Recognition Image Display Distance Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing iris recognition systems in electronic devices face performance deterioration and user dissatisfaction due to the need for high-resolution image capture and continuous display of facial or iris images, which can lead to aesthetic issues and unintended exposure of iris information, while providing text-based feedback for distance adjustment complicates intuitive alignment.
Innovation Solution
An electronic device and method that uses image processing to display different images based on the distance between the device and the user's eye, guiding the user to an appropriate iris-recognizable position without continuously displaying facial or iris images, thereby preventing information leakage and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution images are continuously captured and displayed to provide a preview screen for iris recognition, then the recognition accuracy is improved, but the device performance deteriorates and user privacy is compromised
Solution Approach 1:
The patent extracts only the essential information needed for iris recognition (distance measurement and alignment guidance) while discarding the continuous display of high-resolution facial images. This is achieved by using depth sensors to measure distance and displaying simplified visual cues instead of continuous high-resolution video feeds, thereby reducing processing load while maintaining recognition accuracy.
Solution Approach 2:
Instead of continuously capturing and displaying full high-resolution images, the system performs partial action by capturing only sufficient data points for distance measurement and providing minimal visual feedback necessary for alignment. This reduces the excessive processing of unnecessary image data while maintaining the core functionality of iris recognition.
2Ease of operation
If the user's face or eye images are continuously displayed on the preview screen, then the user can see the alignment status, but aesthetic appeal is reduced and iris information may leak without user intention
Solution Approach 1:
The patent extracts only the necessary alignment information and presents it through simplified visual cues such as icons or minimal graphical indicators rather than displaying the actual facial or iris images. This allows users to understand alignment status without exposing sensitive biometric information publicly.
Solution Approach 2:
The system introduces an intermediary representation layer between the actual iris image and the display output. Instead of showing raw iris or facial images, the patent uses processed visual indicators that convey alignment status without revealing sensitive biometric data, thus protecting user privacy while maintaining ease of operation.
3Loss of information
If text-based feedback messages are provided to guide distance adjustment, then information is conveyed to the user, but intuitive alignment becomes difficult and user interaction is complicated
Solution Approach 1:
The patent replaces text-based feedback (informational system) with visual icon-based feedback (intuitive system). Instead of requiring users to read and interpret text messages about distance adjustment, the system displays intuitive visual icons that immediately convey whether the user should move closer or farther, making the interaction more natural and easier to understand at a glance.
Solution Approach 2:
The system uses color variations in visual icons to convey different distance states and alignment statuses. Different colors provide immediate visual feedback about whether the user is at the correct distance, needs to move closer, or needs to move farther, enhancing intuitiveness without requiring text interpretation.
