Content Viewer for Persistent Accessibility Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to provide a user-friendly, accessible way to customize the appearance of online content for users with disabilities, requiring HTML knowledge and losing CSS styling changes when the URL changes or the web page is refreshed.
Innovation Solution
A content viewer system that allows users to customize the appearance of online content without HTML knowledge, storing modifications in a user profile repository for consistent rendering across different views, and providing options like Dyslexia, Large Print, and Nighttime modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional CSS customization is used, then content appearance can be modified, but users require HTML knowledge and changes are lost when URL changes or page is refreshed
Solution Approach 1:
The patent introduces a content viewer as an intermediary component between the web browser and the online content. This content viewer captures and renders content, allowing CSS modifications to be applied and persisted within the viewer itself rather than relying on browser-based CSS hacks. The viewer acts as a stable intermediary that maintains customization across different URLs and page refreshes.
Solution Approach 2:
The patent creates a copy of the content within the content viewer environment. By capturing and rendering content in this isolated viewer context, the system can apply persistent CSS modifications to the copied content without affecting the original web page. This copying mechanism allows customizations to survive navigation and refresh operations.
2Adaptability or versatility
If third party content viewers are used, then content rendering can be customized, but different viewers present different user experiences
Solution Approach 1:
The patent implements a universal content viewer that can handle multiple types of online content (HTML, PDF, images, videos) through a single interface. This multi-functional viewer provides consistent rendering and customization capabilities across different content types and third-party sources, eliminating the need for users to adapt to different viewers for different content.
Solution Approach 2:
The content viewer employs dynamic rendering capabilities that adapt to different content types while maintaining a consistent user interface. The viewer can dynamically adjust its rendering behavior based on the content being displayed, yet preserves persistent CSS modifications and a uniform interaction model across all content types.
3Adaptability or versatility
If CSS styling changes are applied in conventional web pages, then content appearance can be modified, but changes disappear when the web page is refreshed
Solution Approach 1:
The patent applies CSS modifications in advance within the content viewer before the content is fully rendered and displayed to the user. By establishing the customized rendering context beforehand in the viewer, the system ensures that styling changes are baked into the rendered content and persist through refresh operations, rather than being applied and lost on each page load.
Solution Approach 2:
The content viewer serves itself by maintaining its own rendering context and CSS modification state independently from the host web page. When the web page is refreshed, the content viewer retains its customized rendering capabilities and applies them again, making the viewer self-sufficient in maintaining styling persistence without relying on the host page's state.
