Document Page Enlargement and Pointer Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems can only enlarge the cover page of a multi-page document, making it difficult to transition to other pages, hindering efficient content confirmation.
Innovation Solution
An information processing system with a screen display unit and an enlarging display unit that allows users to enlarge and navigate through multiple pages of a document by moving a pointer over the displayed image, enabling seamless page switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only the cover page is enlarged for display, then the display clarity of the current page is improved, but the ability to navigate to other pages is lost
Solution Approach 1:
The patent divides the multi-page document into separate selectable regions, where each page can be independently accessed. The cover page is segmented as the default display, while other pages are segmented as selectable alternatives, allowing users to navigate between them without losing the enlarged display state.
Solution Approach 2:
The patent adds a temporal dimension to the display by allowing users to switch between different pages (time dimension) while maintaining the spatial enlargement. This enables navigation through the document's page sequence without reducing the display magnification, effectively adding a time-based navigation layer to the spatial display.
2Ease of operation
If the document is displayed in full multi-page view, then all pages are accessible, but the display size of each page becomes too small to read
Solution Approach 1:
The patent implements a dynamic display mode where the system automatically switches between full multi-page view and enlarged single-page view based on user interaction. When a user hovers over or selects a page, the system dynamically transitions from showing all pages at small size to displaying the selected page at large readable size, making the interface adaptive to user needs.
Solution Approach 2:
The patent introduces an intermediary selection mechanism (such as hover detection or click interaction) that mediates between the user's need to access multiple pages and the need for readable display. This intermediary action triggers the transition from the thumbnail view to the enlarged view, serving as a bridge between the two display states.
3Productivity
If pointer movement controls page switching, then navigation efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent implements a self-service navigation system where the interface automatically detects pointer movement and autonomously switches pages without requiring additional user actions. The system monitors pointer position and automatically transitions between pages based on the detected movement, making the navigation process intuitive and reducing the cognitive load on the user.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors pointer position and provides visual feedback (such as highlighting or preview) before executing the page switch. This feedback loop allows users to anticipate the navigation action and confirms the system's response to their input, making the interaction more predictable and controllable.

AI summary
An information processing system comprising: a screen display unit that displays on a screen a document image representing document data including a plurality of pages; and an enlarging display unit that, when a pointer is located on the document image, enlarges and displays one of the plurality of pages of the document data and changes the page to be displayed according to a movement of the pointer on the displayed page.
