Mobile Terminal Automatic Scrolling for Large Document Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in displaying and editing documents with sizes greater than their screen dimensions, leading to difficulties in recognizing full content, as they cannot output the entire document without reducing its size.
Innovation Solution
A mobile terminal with a touchscreen display and controller that automatically scrolls panoramic files, allowing users to view and edit documents larger than the screen size by displaying a first portion and scrolling in at least one direction to reveal additional portions, along with features like mini-maps and touch input for precise scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a document size is extended to insert a considerable amount of data, then the data storage capacity is improved, but the user's ability to recognize the full content of the document deteriorates
Solution Approach 1:
The patent creates a virtual copy of the full document content displayed as an overlay or popup window showing a thumbnail or reduced representation of the entire document. This virtual copy allows users to see the full content structure without changing the actual large document size, resolving the contradiction between storing大量 data and maintaining content recognizability.
Solution Approach 2:
The patent introduces a new dimensional approach by displaying document navigation and full content overview in a separate spatial dimension (popup overlay) rather than expanding the main document view. This allows the large document to maintain its extended size for data storage while providing content recognizability through a parallel dimensional representation.
2Quantity of substance
If a document size is extended to insert a considerable amount of data, then the data storage capacity is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent performs preliminary actions by automatically generating a thumbnail or reduced preview of the full document content and displaying it before the user begins editing. This preliminary visualization helps users understand the document structure and locate specific areas, making subsequent editing operations easier despite the large document size.
Solution Approach 2:
The patent creates a virtual copy of the document structure for navigation purposes, allowing users to interact with this simplified representation to quickly navigate the large document. This copying approach separates the navigation function from the editing function, improving ease of operation while maintaining large data storage capacity.
3Ease of operation
If automatic scrolling is implemented to display full content, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service automatic scrolling where the system automatically generates and displays the thumbnail overview, and the scrolling behavior is triggered automatically based on user interaction with the thumbnail or document edges. This self-service approach improves ease of operation while minimizing the perceived complexity by making the automation transparent to the user.

AI summary
A mobile terminal including a memory configured to store data; a touchscreen display; and a controller configured to: display a first portion of a panoramic file selected from the memory, said panoramic file having a display size greater than that of the touchscreen display, and scroll automatically the panoramic file in at least one direction so as to display another portion of the panoramic file.
