Dynamic Presentation Pagination Control via Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying dynamic-length presentations on various devices lack control over pagination, leading to unpredictable user experiences due to the inability to recognize specific display device characteristics, resulting in inefficient and inconvenient rendering of presentations.
Innovation Solution
A method and computer-readable medium that allow authors to specify pagination preferences, record metadata for each page, and adapt the presentation to display devices of different sizes, ensuring that the presentation is rendered with the intended user experience by determining the number of pages required and selecting the appropriate pages for display based on metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed size pages (PDF) are used, then the presentation structure is maintained, but the user experience deteriorates due to zooming and panning requirements
Solution Approach 1:
The patent applies dynamics by making the presentation structure adaptable rather than fixed. The system dynamically adjusts page layout, element positioning, and content distribution based on the actual display device characteristics (screen size, resolution, orientation). This allows the presentation to maintain structural integrity while automatically optimizing for different device formats, eliminating the need for manual zooming and panning.
2Ease of operation
If multiple versions of presentation are designed for various screen sizes, then the user experience is improved for each device type, but the authoring complexity and time consumption significantly increase
Solution Approach 1:
The patent implements universality by creating a single presentation authoring process that serves multiple display device types. The system uses a standardized set of presentation elements with defined properties (position, size, flow characteristics) that can be universally applied across different devices. The rendering engine automatically adapts these universal elements to specific device characteristics, eliminating the need for authors to create separate versions for each device type.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting presentation parameters (page breaks, element positioning, text flow) based on display device parameters (screen dimensions, resolution, orientation). Instead of creating multiple static versions, the system modifies these parameters at runtime based on the target device, allowing a single authored presentation to optimize itself for different viewing contexts.
3Adaptability or versatility
If conventional template language approaches are used, then the presentation can be adapted to different devices, but the authoring difficulty increases due to requiring considerable knowledge of template language
Solution Approach 1:
The patent applies this principle by replacing complex, persistent template language requirements with simpler, more transient markup elements. Instead of requiring authors to master sophisticated template languages, the system uses streamlined markup with basic elements that can be easily defined and modified. These simplified markup objects serve their purpose during rendering and can be easily adjusted without requiring deep knowledge of complex template systems.

AI summary
A method and computer readable medium for defining pagination preferences that control pagination of dynamic-length presentations. In an embodiment, a computer implemented method for specifying pagination preferences comprises, identifying pagination preferences for each page of an original presentation, recording the starting point and ending point within the primary text flow that appear on each page, associating the elements with the page on which the elements are located and storing the pagination preferences, starting and ending points in the primary text flow, and page elements as metadata associated with each page.
