Adaptive ROI and Cursor Control in Content-Aware Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack the ability to efficiently determine and control a region of interest based on content components, leading to suboptimal user interaction and cursor management.
Innovation Solution
A display apparatus with a controller that determines a region of interest in the display area based on layout, user behavior, and content components, and adjusts the region's size and cursor characteristics accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus uses a fixed region of interest and cursor characteristics, then the device complexity is reduced, but the adaptability to different content and user needs deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the region of interest boundaries and cursor characteristics based on real-time analysis of content components and user interaction patterns. The controller continuously modifies the ROI size, position, and cursor properties (such as speed, size, and shape) to adapt to different content types and user needs, transforming a static system into a dynamic one that responds to changing conditions
Solution Approach 2:
The display apparatus performs automatic analysis of content components (text, images, videos, icons) and user behavior patterns to autonomously determine and adjust the region of interest and cursor characteristics without requiring manual user configuration. The system serves itself by automatically optimizing display parameters based on the displayed content and observed user interactions
2Quantity of substance
If the region of interest size is increased to accommodate more content components, then the information coverage is improved, but the user's focus on critical elements deteriorates
Solution Approach 1:
The patent applies different quality levels to different regions within the display area by dynamically adjusting the region of interest boundaries to provide enhanced focus on critical content elements while maintaining broader context visibility. The ROI is selectively expanded or contracted based on the importance and type of content components, creating zones of varying attention intensity that match user needs for both detailed focus and overall comprehension
3Ease of operation
If the cursor characteristics are adjusted frequently to match content changes, then the user interaction effectiveness is improved, but the system response time and processing load deteriorates
Solution Approach 1:
The patent implements periodic analysis of content components and user behavior patterns at predetermined intervals or upon significant content changes, rather than continuously adjusting cursor characteristics. This periodic update mechanism balances the need for responsive interaction with the constraint of system processing capacity, reducing unnecessary adjustments while maintaining effective user interaction

AI summary
A display apparatus includes a display area in which an image is displayed; and a controller for determining a region of interest in the display area and controlling a size of the region of interest based on components of content displayed in the region of interest.
