Document Annotation Space Expansion via Font Formatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited display size of electronic devices such as mobile phones and tablets leads to a restricted blank region in document files, causing annotation content to overlap with the original content, resulting in a poor reading experience for users.
Innovation Solution
The method involves adjusting the font format and/or paragraph format of content in document files to reserve more blank regions for annotation, preventing overlap with the original content and enhancing the reading experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size of electronic devices is limited, then the blank region for annotation is restricted, but adding annotation content causes overlap with original content
Solution Approach 1:
The patent changes the font parameters (size, weight, style) and paragraph parameters (line spacing, indentation) of the document content to create additional blank regions. By adjusting these formatting parameters, the system reserves space for annotation content without requiring a larger display screen, thus preventing overlap between annotations and original content while maintaining the same physical display area.
2Area of stationary object
If font format and paragraph format are adjusted to reserve more blank regions, then annotation space increases, but display content may be reduced
Solution Approach 1:
The patent applies local quality by adjusting font and paragraph formats only in specific regions where blank space is needed for annotation, rather than uniformly changing the entire document's formatting. This allows the system to create annotation space in targeted areas while preserving the original display content and formatting in other regions, thus preventing information loss.
3Ease of operation
If annotation content is added to limited blank regions, then reading experience deteriorates due to overlap, but increasing display size is not feasible
Solution Approach 1:
The patent resolves the contradiction by changing font and paragraph formatting parameters to create additional blank regions within the existing display size constraints. This approach improves reading experience by preventing content overlap while maintaining the same physical display area, making it feasible for portable devices with limited screen real estate.

AI summary
An annotation method and an electronic device are provided. The method includes: An electronic device displays content of a first file in a first interface. The electronic device detects a preset operation in the first interface, and displays the second interface including a first region and a second region. The first region is used to display the content of the first file, the second region is used to display annotation content. A font format and/or a paragraph format of at least a part of words in the first region are/is different from a font format and/or a paragraph format of words in the first file in the first interface.
