Browser Content Enhancement via Element Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing progressive enhancement techniques face inefficiencies in selecting content to enhance, determining whether to create low or high fidelity variants, and coordinating enhancements across independently authored content, leading to errors and latency issues.
Innovation Solution
A method and system that utilize a user agent to parse documents, identify elements marked for enhancement, and replace low fidelity versions with high fidelity variants using a registry of enhancements and factories, ensuring efficient and timely delivery of rich interactive elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If progressive enhancement is implemented by delivering low fidelity content first and then enhancing with high fidelity variants, then latency is reduced and user experience is improved, but complexity increases in selecting content to enhance, determining fidelity variants, and coordinating enhancements
Solution Approach 1:
The patent segments content into distinct fidelity variants (low fidelity and high fidelity versions) and delivers them separately. The low fidelity variant is delivered first for immediate display, while high fidelity variants are delivered progressively and applied through targeted replacements. This segmentation allows the system to manage complexity by handling smaller, discrete content units rather than entire documents, resolving the contradiction between reduced latency and increased complexity.
2Reliability
If existing progressive enhancement techniques are used to select and enhance content elements, then high fidelity content can be delivered progressively, but errors occur and redundant book-keeping is required due to inefficiencies in selecting content and coordinating enhancements
Solution Approach 1:
The patent applies preliminary action by pre-marking content elements with enhancement attributes during the authoring or preprocessing stage. Elements that are candidates for enhancement are identified and tagged in advance with metadata indicating their enhancement potential and replacement rules. This preliminary classification eliminates the need for complex runtime selection logic and redundant book-keeping, allowing the system to reliably replace marked elements with high fidelity variants without errors or inefficiencies.
3Adaptability or versatility
If more complex high fidelity content is delivered, then richer interactive elements are provided, but delivery time increases and user access is delayed
Solution Approach 1:
The patent applies local quality by delivering different fidelity levels to different content elements based on their individual enhancement attributes rather than applying a uniform fidelity level to the entire document. Low fidelity variants are delivered immediately for fast access, while high fidelity variants are selectively delivered and applied to specific marked elements. This allows the system to provide rich interactive elements where needed without delaying overall content delivery, resolving the contradiction between content richness and delivery speed.
Data Source
AI summary
A method, system and computer program product for progressive enhancement of content in a browser. The method includes receiving a document with content containing a plurality of elements and parsing the received content with at least one processor. The method also includes identifying a subset of the plurality of elements that are marked for enhancement and replacing each of the element in the identified subset with their respective enhancement to obtain the document with the enhanced elements.
