Display Control Method for Document Page Outline Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to easily grasp the outline of a desired page in document displays, as existing systems require character input for electronic sticky notes, making it cumbersome.
Innovation Solution
A display control method that adds an object (sticky note) extending outside the image face of a thumbnail image when a user operation is received, and moves a second image in a predetermined direction, allowing users to easily identify and process desired pages without character input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic sticky notes require character input to grasp page outlines, then information can be recorded, but user operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent extracts the essential function of sticky notes from character input to visual marking. Instead of requiring users to input text to annotate pages, the system allows direct placement of sticky note objects on thumbnail images, extracting only the necessary visual indication function while eliminating the cumbersome text input requirement.
Solution Approach 2:
The patent uses visual copies or representations of sticky notes placed on thumbnail images to represent page outlines. These visual markers serve as simplified copies of the traditional sticky note concept, providing immediate visual recognition without requiring the full functionality of text-based annotation.
2Loss of information
If multiple page images are displayed side by side, then users can compare pages, but it becomes difficult to identify and process desired pages
Solution Approach 1:
The patent employs visual differentiation through sticky note markers that can be distinguished by color or appearance from the surrounding thumbnail images. These colored or distinct visual markers make desired pages stand out among multiple displayed pages, enabling quick identification without requiring users to examine each thumbnail in detail.
Solution Approach 2:
The sticky note objects serve as intermediary markers between the user and the page content. Instead of directly interacting with or examining multiple thumbnail images to identify the desired page, users place these intermediary markers on target pages, which then visually indicate which pages require attention or processing.
3Loss of information
If sticky notes extend outside the image face of thumbnails, then visibility is improved, but image area is reduced
Solution Approach 1:
The patent resolves the space conflict by allowing sticky notes to extend into the spatial dimension beyond the thumbnail image boundaries. Instead of constraining sticky notes within the limited thumbnail area, the system permits them to protrude outward, utilizing the surrounding display space to ensure full visibility while maintaining the compact thumbnail layout.

AI summary
In a display control method for displaying a first image and a second image each indicating a page constituting a document side by side on a virtual axis of a display face, the method includes adding, to the first image, an object extending outside an image face of the first image when a first operation is received from a user on the first image; and moving the second image in a predetermined direction when a second operation is received from the use on the second image.
