E-book Summary Data Generation via Character Region Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional e-books and e-notes make it difficult for users to preview summaries of indexed content, as they rely on generating and using handwritten or underlined page indices as shortcuts, which are inconvenient for previewing summarized data.
Innovation Solution
An apparatus and method that includes an input data recognizer, character region extractor, and summary data generator to recognize user input data, extract relevant character regions, and generate summary data, allowing users to preview e-book or e-note content as summarized images or documents, with the option to directly access indexed pages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional e-books generate index of handwritten or underlined pages for shortcut navigation, then navigation speed is improved, but the ability to preview summarized content deteriorates
Solution Approach 1:
The patent segments the indexed content into extractable character regions, separating the navigation function (index) from the content preview function (summary data). This allows the system to maintain fast index-based navigation while simultaneously generating previewable summary content from the same indexed regions.
Solution Approach 2:
The patent adds a new dimension by generating summary data in a different format (extracted character regions) from the indexed content. This creates a parallel representation that enables preview functionality without interfering with the original index-based navigation system.
2Quantity of substance
If e-books store only page and paragraph unique numbers for indexed content, then storage efficiency is improved, but user convenience for content preview deteriorates
Solution Approach 1:
The patent performs preliminary extraction of character regions and generation of summary data in advance, storing this extracted content alongside the index information. This preliminary action enables users to preview content directly without requiring additional processing during interaction.
Solution Approach 2:
The patent creates a copy of the indexed content in the form of extracted character regions and summary data. This copy serves the preview function while the original compact index structure maintains storage efficiency, allowing both goals to coexist.
3Productivity
If e-books use shortcut navigation to selected indexed pages, then navigation efficiency is improved, but user ability to preview multiple indexed contents simultaneously deteriorates
Solution Approach 1:
The patent merges the index navigation function with the summary preview function by generating summary data from the same indexed character regions. This merging allows users to access both navigation efficiency (through the index) and preview versatility (through the generated summaries) from a unified system.
Data Source
AI summary
An apparatus and method for generating summary data of an e-book or e-note, the method including if input data is received, recognizing a type of the input data, extracting a character region in the e-book or e-note corresponding to the recognized input data type, storing page information corresponding to the extracted character region, and generating summary data by using the page information corresponding to the character region when the generation of the summary data is requested, thereby allowing a user to preview summary content handwritten by the user on the e-book or e-note at a glance.
