Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing rapid eLearning tools lack the ability to efficiently convert PDF documents into SCORM-compliant online courses with rich interactive and multimedia features, failing to provide granular analytics and requiring manual coding or specialized software, while existing solutions like SCORM wrappers only offer basic tracking without interactive capabilities.

Innovation Solution

An enhanced and extended PDF Web reader with unique URL encoding enables the creation of SCORM-compliant online courses directly from PDF documents, incorporating multimedia, interactive content, and granular analytics, allowing for seamless integration with LMSs and supporting features like annotation, downloadable courses, and offline access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SCORM wrappers are used to make PDF documents SCORM-compliant, then basic tracking capability is achieved, but interactive capabilities and granular analytics are lost

Engineering Contradiction:

ImproveSCORM complianceVSAvoidinteractive capabilities

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

A JavaScript intermediary layer is embedded within the PDF document to act as a mediator between the PDF content and the SCORM compliance requirements. This intermediary captures user interactions with PDF elements (links, buttons, forms, annotations) and translates them into SCORM-compliant tracking events, enabling both SCORM compliance and interactive capabilities to coexist

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/scorm-wrapper-only approach with a software-based JavaScript event capture system. Instead of relying solely on SCORM wrapper metadata, the system uses JavaScript to dynamically capture and report user interactions, enabling granular analytics and interactive tracking without compromising SCORM compliance

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If rapid eLearning tools are used to create SCORM-compliant courses, then interactive and multimedia features are achieved, but the ability to efficiently convert existing PDF documents is lost

Engineering Contradiction:

Improveinteractive featuresVSAvoidPDF conversion efficiency

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent performs preliminary actions by embedding JavaScript tracking code and SCORM compliance infrastructure into the PDF document during the authoring phase, rather than requiring post-processing conversion. This allows existing PDF documents to be directly used as SCORM-compliant courses with interactive features already integrated

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent makes the PDF document multi-functional by enabling it to serve both as a static document format and as an interactive SCORM-compliant course simultaneously. The same PDF file can be viewed in standard PDF readers for basic functionality and in web browsers with JavaScript enabled for full interactive and tracking capabilities

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If manual coding is used to create SCORM-compliant courses with granular analytics, then comprehensive tracking capability is achieved, but development time and cost increase

Engineering Contradiction:

Improvegranular analyticsVSAvoiddevelopment time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The PDF document becomes self-service capable by automatically capturing its own interaction data through embedded JavaScript code. The document monitors and reports its own user interactions (page views, link clicks, form submissions, annotations) without requiring external manual coding or complex tracking infrastructure, enabling granular analytics with minimal development effort

Inventive Principle:

Principle #25Self-service

AI summary

A PDF Web reader enhanced and extended with unique URL encoding makes it possible to use PDF documents as the basis of SCORM-compliant online learning courses and other resources, offering feature sets as comprehensive as those previously achievable only through manual or custom coding of online learning courses, or by using a “rapid eLearning tool” to build one. The invention supports multimedia, including video and audio, and web pages, learning interactions, quizzes, and surveys. It tracks progress, enables content highlighting, notes, and comments, and allows downloading customized documents for personalized learning and future review.
