Adaptive Document Display Layout Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internet content created for personal computers (PCs) is not optimally readable on larger screens like TVs due to the greater viewing distance, leading to reduced readability and difficulty in navigating or finding information, as zooming methods fail to maintain layout and image clarity.
Innovation Solution
An adaptive document displaying apparatus and method that analyzes document components and adjusts layout and content based on user profiles and device attributes, such as screen size, to optimize content presentation on various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire web page is enlarged to improve readability, then the user can view all contents of the enlarged web page, but it is difficult to identify the entire layout of the web page on one screen and the user has to scroll through the web page
Solution Approach 1:
The patent segments the web page into multiple regions (e.g., header, main content, sidebar, footer) and selectively enlarges only the relevant regions rather than the entire page. This allows improved readability of specific content areas while maintaining an overview of the overall page layout, eliminating the need to scroll through the entire enlarged page.
Solution Approach 2:
The patent applies local quality by allowing different regions of the web page to have different enlargement rates. Important content areas can be enlarged to improve readability while less important areas remain at normal size, enabling the user to maintain context of the overall layout while reading detailed content in enlarged regions.
2Device complexity
If part of the web page is enlarged to maintain layout visibility, then the user can identify the entire layout on one screen, but it is difficult to display certain contents in the TV environment and desired information cannot be easily found
Solution Approach 1:
The patent implements dynamic enlargement where the enlargement rate and region can be dynamically adjusted based on user interaction and content importance. The system can switch between different enlargement modes (partial enlargement, full enlargement, region-specific enlargement) to balance layout visibility and readability according to the viewing context and user needs.
3Measurement precision
If the web page is enlarged to an enlargement rate greater than a predetermined enlargement rate, then the user can view text in detail, but it is difficult to view images and text on one screen
Solution Approach 1:
The patent segments the display area into multiple regions with different enlargement rates. High-enlargement regions are allocated to text-heavy areas where detailed reading is needed, while lower-enlargement regions display images and other content. This segmentation allows text detail visibility in critical areas while maintaining efficient use of the overall display area.
Solution Approach 2:
The patent applies different enlargement qualities to different regions: high enlargement rates are applied locally to text regions for detailed readability, while image regions use moderate enlargement rates to maintain their visual quality and fit within the display area, thus balancing text detail visibility with overall display area utilization.
