Controller-Based Interest Information Extraction for Portable Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing information of interest in electronic documents on portable devices due to the large amount of information, requiring a significant number of operations to find desired content.
Innovation Solution
An electronic device and method that displays recommended items indicating user interest information, collected from the document, allowing rapid access through a small number of operations by using a controller to provide these recommendations based on user information, enabling quick navigation and display of relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large amount of information is displayed in an electronic document on a portable device, then the information completeness is improved, but the ease of operation deteriorates due to the difficulty of finding desired information
Solution Approach 1:
The patent segments the large amount of information in the electronic document by extracting and displaying only the user interest information in a recommended item. This divides the complete but overwhelming information into a manageable subset that is directly relevant to the user, allowing them to access desired information quickly without navigating through all the content.
Solution Approach 2:
The controller performs preliminary action by collecting user information from the electronic document and generating a recommended item before the user needs to search. This pre-processing of information based on user preferences allows the system to present only the most relevant content, eliminating the need for users to manually search through large amounts of information.
2Measurement precision
If users search for desired information bit by bit through specific operations, then the measurement precision of information location is improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary action by pre-collecting user information and pre-generating a recommended item that directly points to user interest information. This eliminates the need for users to perform multiple sequential search operations, reducing both the time required and the number of operations needed to locate desired information with high precision.
Solution Approach 2:
The recommended item acts as an intermediary between the user and the large amount of information in the electronic document. Instead of directly searching through all content, users interact with the recommended item which mediates the search process by presenting only the most relevant information, thus reducing time loss while maintaining location precision.
3Quantity of substance
If the electronic device displays all information in the electronic document, then the information completeness is improved, but the device complexity increases due to processing and displaying large data
Solution Approach 1:
The controller applies the extraction principle by taking out only the user interest information from the complete electronic document. Instead of processing and displaying all information, the system extracts the relevant subset based on collected user information, thereby reducing device complexity while maintaining the essential completeness of useful information through the recommended item.
4Ease of operation
If users perform multiple operations to access information of interest, then the ease of operation deteriorates, but the productivity of information retrieval is reduced
Solution Approach 1:
The system performs preliminary action by pre-collecting user information and pre-generating the recommended item before the user needs to retrieve information. This eliminates the need for multiple sequential operations, improving both ease of operation (reducing to one selection action) and productivity (enabling rapid access to information of interest).
Solution Approach 2:
The system applies self-service by automatically collecting user information from the electronic document and generating the recommended item without requiring user intervention. This automated process improves ease of operation by eliminating manual search steps and enhances productivity by quickly presenting relevant information based on user preferences.
