Gaze-Adaptive Display Mode Adjustment for Multi-Content Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content display technologies do not effectively enhance the visibility and engagement of multiple contents, such as advertisements and news, by failing to adapt to the line-of-sight and gazing patterns of viewers, leading to suboptimal display modes and positions.
Innovation Solution
A content display device and method that detects the line-of-sight direction of viewers, identifies gazing points, and determines display modes based on gazing content distribution, adjusting display sizes and positions to optimize content visibility and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple contents are simultaneously displayed on a screen, then the quantity of information provided to users increases, but the visibility and engagement of individual contents decreases
Solution Approach 1:
The patent applies local quality by making different parts of the display have different properties based on user gaze. The display control unit adjusts display modes (size, position, brightness) of individual contents based on gazing point identification, so that each content receives customized display treatment rather than uniform display, thereby maintaining visibility even when multiple contents are shown simultaneously.
Solution Approach 2:
The patent implements dynamics by making the display mode adaptable and changeable in real-time based on detected gazing behavior. The system continuously monitors line-of-sight direction and gazing points, then dynamically adjusts display parameters of contents accordingly, allowing the display to respond to user attention and optimize visibility of relevant contents while managing the quantity of displayed information.
2Adaptability or versatility
If the display mode of each content is fixed, then the device complexity is reduced, but the adaptability to user attention patterns decreases
Solution Approach 1:
The patent applies self-service by enabling the display system to automatically adjust its own behavior based on detected user gazing patterns. The display control unit autonomously determines optimal display modes for each content based on gazing point identification results, without requiring manual configuration or complex external control systems, thereby achieving adaptability while managing complexity through automated decision-making.
Solution Approach 2:
The patent implements feedback by using detected line-of-sight direction and gazing point information to continuously adjust display modes. The system monitors user attention through gaze detection and uses this feedback to dynamically modify content display characteristics, creating a closed-loop system that adapts to user behavior while maintaining manageable complexity through algorithmic control.
3Ease of operation
If notification information is displayed at a fixed position, then the ease of operation is improved, but the user experience regarding sudden impressions worsens
Solution Approach 1:
The patent applies local quality by determining the initial display position of notification information based on the user's gazing point rather than using a fixed position. The display control unit identifies where the user is looking and places notifications in or near that region, making the display location adaptive to user attention while avoiding sudden impressions by placing notifications where the user is already looking.
4Productivity
If the display size of each content is uniform, then the manufacturing precision is simplified, but the effectiveness of content delivery decreases
Solution Approach 1:
The patent applies local quality by setting different display sizes for different contents based on their relevance to user gazing behavior. The display control unit adjusts the size of each content individually according to how closely its position aligns with detected gazing points, making important or gazed-at contents larger and more prominent while keeping less relevant contents smaller, thereby optimizing content delivery effectiveness with differentiated sizing.

AI summary
A content display device includes a line-of-sight direction detection unit, a gazing point identification unit, a gazing content identification unit, and a display control unit. The line-of-sight direction detection unit is configured to detect a line-of-sight direction of a person located in a vicinity of a display region in which a plurality of contents are simultaneously displayed. The gazing point identification unit is configured to, based on the line-of-sight direction, identify a gazing point in the display region of the person. The gazing content identification unit is configured to, based on a distribution of the gazing point detected in a predetermined period, identify a gazing content at which the person is gazing. The display control unit configured to determine a display mode of each of the plurality of contents, based on a result of identifying the gazing content, and display each of the plurality of contents in the display mode determined.
