Eye-Gaze Detection Using Non-Dominant Eye Fluctuation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional line-of-sight detection techniques do not adequately consider a user's intention when processing based on gazing points, leading to suboptimal experiences for users seeking either high immersion or a clear view of the entire video.
Innovation Solution
A line-of-sight detecting device that includes a processor to detect the lines of sight of both eyes, determine a dominant eye, and control processing based on the fluctuation of the non-dominant eye's line of sight to enhance user experience by adjusting depth of field and interaction responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If processing is controlled based on the gazing point of the dominant eye only, then the device complexity is reduced, but the user immersion and experience quality deteriorate
Solution Approach 1:
The patent segments the line-of-sight detection into two independent parts: dominant eye line-of-sight for gazing point detection and non-dominant eye line-of-sight for fluctuation amount detection. This segmentation allows each eye's data to be processed separately and combined, resolving the contradiction by maintaining simplicity in gazing point calculation while adding fluctuation-based control for enhanced user experience.
Solution Approach 2:
The patent introduces dynamic control of processing based on the fluctuation amount of the non-dominant eye's line of sight. The control unit dynamically adjusts processing parameters according to real-time fluctuation measurements, enabling the system to adapt between immersion mode (low fluctuation) and overview mode (high fluctuation), thus improving user experience quality without excessive complexity.
2Reliability
If the depth of field is controlled to enhance immersion, then user immersion is improved, but the ability to capture the entire video deteriorates
Solution Approach 1:
The patent makes the depth of field control dynamic by linking it to the fluctuation amount of the non-dominant eye's line of sight. When fluctuation is small (indicating focused attention), the system enhances immersion with narrow depth of field. When fluctuation increases (indicating scanning or overview needs), the system automatically adjusts to provide broader video capture. This dynamic adaptation resolves the contradiction between immersion and versatility.
Solution Approach 2:
The system uses feedback from the non-dominant eye's line-of-sight fluctuation to automatically adjust processing parameters. The control unit continuously monitors fluctuation amount and uses this feedback to modulate the depth of field and other processing aspects, creating a closed-loop system that adapts to user intent without manual intervention, thus maintaining both immersion and capture flexibility.
3Ease of operation
If processing is made responsive to user intention, then user friendliness is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by using the user's own physiological data (line-of-sight fluctuation of the non-dominant eye) to automatically control processing parameters. The system detects user intention through natural eye movement patterns and autonomously adjusts depth of field, focus, and other processing aspects without requiring explicit user commands, thereby improving friendliness while keeping the complexity manageable through biomimetic control.
