Electronic File Display System Using QR Code Page Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face significant time consumption when searching for specific pages within electronic files, such as manuals, associated with information processing apparatuses like personal computers and multifunction peripherals.
Innovation Solution
An electronic file display system that includes an information processing apparatus and a display device, which uses a code image to acquire identification information for specifying the electronic file and page information, allowing direct display of the desired page without manual searching, utilizing a first display unit for operation screens and a second acquisition unit to retrieve and display the specific page from the electronic file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually search for desired pages in electronic files, then they can access the information, but the time consumption for searching is significant
Solution Approach 1:
The system performs preliminary actions by embedding identification information (QR codes or barcodes) directly on the pages of electronic files before distribution. When users scan these codes with their mobile phones, the system automatically identifies and retrieves the specific page content, eliminating the need for manual searching through the entire document.
Solution Approach 2:
The patent introduces an intermediary mechanism (QR code or barcode) that serves as a bridge between the physical/digital document and the digital retrieval system. This intermediary contains encoded page identification information that enables automatic page localization, transforming a manual search process into an automated retrieval process.
2Productivity
If electronic files are distributed without page identification mechanisms, then distribution is simple, but users cannot quickly locate specific pages
Solution Approach 1:
The system creates a simplified copy of page identification information in the form of QR codes or barcodes that can be scanned by mobile devices. Instead of requiring complex metadata structures or database systems, the patent uses these visual code copies to encode essential page identification data, enabling efficient retrieval while maintaining simple file distribution.
Solution Approach 2:
The patent transforms the representation of page identification from traditional text-based or metadata-based parameters into visual code parameters (QR codes/barcodes). This parameter change enables rapid optical scanning and automatic recognition by mobile phone cameras, dramatically improving retrieval efficiency without significantly increasing structural complexity.
Data Source
AI summary
A display device notifies a server device of identification information for specifying an electronic file to be displayed. The server device specifies the electronic file and page information based on the notified identification information to transmit the electronic file and the page information to the display device. The display device displays, as an initial screen, a specified page of the received electronic file based on the received electronic file and page information.
