Dynamic Document Layout and Ad Control for Small Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic content publishers face challenges in displaying documents on various devices, as current software fails to consider target display window geometry and default font size, leading to cumbersome layouts on small devices like digital media players and mobile phones.
Innovation Solution
A method is introduced to dynamically select page masters and styling rules based on display parameters, allowing for adaptable layouts that can change from three columns to a single column and adjust font sizes, and to enable or disable ad content based on document attributes, improving readability and visual appeal across different window sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed multi-column layout is used for document display, then the document structure is maintained consistently, but the readability and visual appeal deteriorate on small display devices
Solution Approach 1:
The patent implements dynamic page layout that automatically adapts to different display device characteristics. The system detects the target display window geometry and font size, then dynamically selects appropriate page masters and styling rules to optimize the layout. This allows the document to transition from fixed multi-column layouts on large screens to single-column layouts on small devices, resolving the contradiction between layout consistency and readability.
Solution Approach 2:
The system changes layout parameters based on display conditions by selecting from multiple predefined page masters with different column configurations. When the display window size or font size exceeds thresholds, the system switches to page masters with fewer columns or single-column layouts, thereby adjusting the layout parameters to maintain readability while preserving document structure.
2Quantity of substance
If advertisements are always displayed in addition to document content, then ad revenue is maximized, but the document readability and user experience deteriorate
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different content regions. Advertisements are placed in distinct visual regions separate from the main document content, allowing the document area to maintain its readability while ad regions provide commercial content. The system can selectively enable or disable ads in specific regions based on document attributes without affecting the overall document readability.
3Ease of operation
If the layout is adapted to different display sizes, then readability on various devices is improved, but the system complexity increases
Solution Approach 1:
The system resolves complexity by performing preliminary actions during document creation or publication. Page masters and styling rules are pre-configured with different layout parameters for various display conditions. When the document is displayed, the system simply selects the appropriate pre-prepared layout configuration based on the detected display characteristics, avoiding the need for complex real-time layout calculations and reducing system complexity while maintaining adaptability.

AI summary
Methods, systems and program products for providing a first visual region, the first visual region configured to present content determined by a document. A distinct second visual region is provided, the second visual region not defined by the document and configured to present content that is not contained in the document. One or more attributes are identified in the electronic document. Based on the one or more attributes, the presentation of ad content in the second visual region is enabled or disabled. The electronic document is presented in the first visual region.
