Electronic Document Legibility Analysis via Tracking, Leading, and Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lay individuals creating documents with computer authoring tools often produce illegible text due to lack of expertise in typographic modifications, and they may not recognize or know how to improve legibility without professional evaluation.
Innovation Solution
A method and system that analyze and improve the legibility of electronic documents by focusing on three key parameters: tracking between letters, leading between lines, and visual luminance contrast, allowing for independent analysis and adjustment of these parameters to ensure optimal legibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If computer authoring tools are made accessible to lay persons, then ease of document creation is improved, but document legibility deteriorates
Solution Approach 1:
The system enables lay persons to automatically evaluate and improve their own document legibility without professional intervention. The legibility analysis component allows users to self-diagnose and self-correct typographic issues through automated feedback on tracking, leading, and luminance contrast parameters.
Solution Approach 2:
The system provides automated feedback to users about legibility issues in their documents. By analyzing tracking, leading, and luminance contrast parameters and comparing them against established limits, the system informs users of specific problems and guides them toward corrections, transforming the document creation process into a feedback-driven improvement cycle.
2Manufacturing precision
If professional evaluation is used to ensure document legibility, then document legibility is improved, but device complexity and cost increase
Solution Approach 1:
The system extracts only the three most critical legibility parameters (tracking, leading, luminance contrast) from the full spectrum of typographic considerations. By focusing exclusively on these essential elements and comparing them against established limits, the system achieves professional-grade legibility evaluation without requiring complex comprehensive analysis or professional expertise.
3Measurement precision
If comprehensive typographic analysis is performed, then legibility assessment accuracy is improved, but analysis time and computational resources increase
Solution Approach 1:
The system extracts and analyzes only the three most critical legibility parameters (tracking, leading, luminance contrast) rather than performing comprehensive analysis of all typographic elements. This selective approach maintains high assessment accuracy by focusing on the essential factors that most significantly impact legibility while dramatically reducing analysis time and computational requirements.
Solution Approach 2:
The system performs partial analysis by examining only the three most critical parameters needed for effective legibility assessment. Rather than analyzing every possible typographic parameter, the system concentrates resources on these key elements, achieving sufficient accuracy for practical purposes while minimizing time and computational overhead.

AI summary
Legibility of text in an electronic document is analyzed. The analysis involves no more than the following three parameters: tracking between letters in the text; leading between lines of the text; and visual luminance contrast between the letters and text background.
