Text Comparison System Using Direct Buffer Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional document comparison programs are inefficient and error-prone when comparing text within the same document, between different types of documents, or between web pages or email messages, as they require cumbersome copy-and-paste operations.
Innovation Solution
A computer-based system and method that allows direct comparison of text selections from within a single file or from different sources without the need for copy-and-paste operations, using a processor and memory to receive and buffer text selections for comparison, and generate data to display differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional document comparison programs are used to compare text from within the same document or different file types, then the comparison function is limited to traditional document-to-document comparison, but the user must perform cumbersome copy-and-paste operations to use the program
Solution Approach 1:
The patent extracts the text comparison function from the traditional document comparison context and applies it directly to selected text within the same document or different file types. The system allows users to select text portions and compare them directly without extracting and copying to separate documents, thus eliminating the cumbersome copy-paste operations while maintaining the core comparison functionality.
2Adaptability or versatility
If conventional document comparison programs compare the entirety of two documents, then comprehensive comparison is achieved, but the ability to compare specific text selections is lost
Solution Approach 1:
The patent segments the document comparison process by allowing users to select specific text portions for comparison rather than comparing entire documents. The system divides the comparison task into manageable text selections that can be targeted precisely, enabling both specific text comparison and maintaining adaptability to compare any portions of documents as needed.
3Adaptability or versatility
If conventional programs require text to be copied into a new document for comparison, then standard document format comparison is maintained, but support for different file types and web pages is limited
Solution Approach 1:
The patent implements a universal text comparison system that can handle multiple file types (Word documents, spreadsheets, presentations, emails, web pages) through a common interface. The system extracts text from various source types and performs comparison using the same core functionality, eliminating the need for separate processing paths for different file formats while expanding compatibility.
Data Source
AI summary
Systems and methods are disclosed for comparing selections of text to show differences between the two selections. The text may be selected from the same source or from two different sources. In one implementation, a system receives a first selection of text for comparison and places the selection in a first buffer. The system receives a second selection of text for comparison and places the second selection in a second buffer. The system compares the first buffer and the second buffer to determine differences and displays the differences. In some embodiments, the system may allow a user to choose two buffers from among a plurality of buffers for comparison.
