Thumbnail Display Sequential Page Switching via Sliding Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thumbnail display systems only show the first page of documents in a reduced size, limiting user interaction and ability to preview or switch between pages efficiently.
Innovation Solution
A thumbnail display apparatus that includes a display, a touch panel for detecting sliding operations, and a controller for sequentially switching pages based on user input, allowing users to navigate through multiple pages by sliding on the thumbnail images, with adjustable switching intervals and display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only the first page thumbnail is displayed, then the device complexity is low, but the user interaction capability and page preview efficiency are limited
Solution Approach 1:
The thumbnail display transitions from a static single-image display to a dynamic multi-page sequence display. The controller dynamically switches between different page thumbnails based on detected sliding operations, enabling users to navigate through multiple pages interactively while maintaining a relatively simple display structure.
Solution Approach 2:
The system automatically sequences and displays multiple page thumbnails in response to user sliding operations without requiring complex manual navigation. The controller autonomously manages the thumbnail switching based on simple touch input, reducing the need for complex navigation controls while enhancing user interaction.
2Loss of information
If multiple pages are displayed simultaneously, then the information visibility is improved, but the display area per thumbnail is reduced
Solution Approach 1:
The document information is segmented into multiple individual page thumbnails that can be sequentially displayed. Instead of showing all pages at once which would reduce individual thumbnail size, the system divides the content into discrete page units and allows users to navigate through them sequentially, maintaining large display area for each thumbnail while providing access to all information.
Solution Approach 2:
The system transitions from displaying multiple thumbnails in a spatial arrangement (2D grid) to displaying them sequentially in time (1D temporal sequence). This dimensional change allows each thumbnail to maintain its full display area while still providing access to multiple pages through the time-based sequencing enabled by sliding operations.
3Ease of operation
If manual page navigation is implemented, then the user control is improved, but the operation time and complexity increase
Solution Approach 1:
The system implements periodic automatic page switching based on detected sliding operations. Once a sliding gesture is detected, the controller automatically cycles through pages at predetermined intervals, allowing users to simply slide to initiate navigation rather than performing repeated manual selection operations. This reduces both the time and complexity of multi-page navigation while maintaining user control.

AI summary
A thumbnail display apparatus includes a display that displays, one by one, thumbnail images corresponding to plural pages included in a document, the thumbnail images being generated by reducing images of the corresponding pages included in the document to a predetermined size, a detecting unit that detects a sliding operation of an object, the sliding operation being performed when the thumbnail image displayed by the display being touched by the object, and a controller that performs, in response to detection of the sliding operation by the detecting unit, page switching so as to sequentially switch the page of the document whose thumbnail image is being displayed by the display to other pages.
