Automatic Text Legibility Adjustment via Stored Font Preferences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic readers must manually adjust text size and font characteristics each time they open an electronic document, which is inconvenient and affects legibility, as preferences vary among individuals.
Innovation Solution
A method and apparatus that determine user preferences for font size characteristics by displaying sample text and recording adjustments, then apply these preferences to display electronic documents at optimal zoom levels for improved legibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of zoom level is required each time a document is opened, then text legibility can be customized to user preference, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The system automatically determines user preferences and applies them without requiring manual intervention. The apparatus stores determined preferences and automatically retrieves and applies them when documents are opened, allowing the system to serve itself rather than requiring continuous user input.
Solution Approach 2:
User preferences are determined in advance and stored for future use. Instead of requiring users to adjust settings each time, the system performs the preference determination action beforehand and reuses the results, eliminating repetitive manual adjustments.
2Measurement precision
If manual zoom adjustment is required for each document, then text size can be optimized for reading comfort, but time consumption increases
Solution Approach 1:
The system determines user preferences in advance and stores them for rapid retrieval. When a document is opened, the pre-determined preferences are automatically applied without requiring time-consuming manual adjustment, thus preserving reading comfort while eliminating time loss.
Solution Approach 2:
The system uses feedback from initial user adjustments to automatically determine preferences. By monitoring and analyzing user adjustment patterns, the system learns optimal settings and applies them automatically, reducing time consumption while maintaining reading comfort.
3Adaptability or versatility
If zoom level must be manually adjusted each time, then text display can be personalized, but device complexity increases
Solution Approach 1:
The apparatus automatically manages personalization by storing and retrieving user preferences without requiring complex user interactions. The system handles the complexity internally through automatic preference determination and application, maintaining personalization while simplifying user operations.
Solution Approach 2:
The system copies and reuses determined preferences across multiple document openings. Instead of requiring users to re-adjust settings for each document, the system copies the stored preferences and applies them automatically, maintaining personalization while reducing operational complexity.

AI summary
A computer implemented method and apparatus for automatically improving legibility based on preferred font characteristics. The method comprises determining a plurality of preferences regarding font size characteristics of sample text; receiving a request to view an electronic document having text in a given font; and displaying text of the electronic document in the given font with a zoom level based on the preferences.
