Touch Screen Terminal Chapter Navigation via Directory Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locating chapters or sections in electronic documents on touch screen terminals are inefficient and inaccurate, particularly when dealing with large chapter/section lists, leading to poor user experience.
Innovation Solution
A method and system for touch screen terminals that generate a directory listing for electronic documents, allowing users to input a chapter/section number to switch to, matching and previewing the corresponding entry, and switching to it upon confirmation, without the need for bookmarks or browsing through lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user slides on the screen to select the required chapter/section from a numbered list, then the user can navigate through the document, but the switching efficiency is low and the operation is inconvenient when the chapter/section list is very large and the target chapter/section has a large span
Solution Approach 1:
The patent segments the chapter/section selection process into two parts: (1) a condensed directory list showing only chapter-level entries with their starting page numbers, and (2) a detailed preview panel showing the first page content of the selected chapter. This segmentation allows users to quickly locate chapters without scrolling through every section, significantly reducing switching time while maintaining ease of operation.
Solution Approach 2:
The patent introduces a new dimension by displaying the directory list and preview panel simultaneously in a split-screen layout. The directory list occupies one dimension (left side) while the preview panel occupies another dimension (right side), allowing users to navigate and preview in parallel, thereby improving both operation efficiency and reducing time loss.
2Measurement precision
If bookmarks are used to locate chapters/sections, then switching can be implemented, but the method is inaccurate when too many bookmarks are stored or when the text fragment of the bookmark cannot effectively confirm which chapter/section to switch to
Solution Approach 1:
The patent creates a visual copy of the chapter's first page content in the preview panel, allowing users to accurately identify the chapter/section before switching. This copy mechanism provides clear visual confirmation of the target location, eliminating ambiguity associated with text-based bookmarks while maintaining simple operation without requiring complex bookmark management.
3Loss of information
If a full text is scanned in advance to generate a chapter/section numbered list, then the document structure is organized, but the user experience is poor when the list is very large and requires continuous sliding to find the required chapter/section
Solution Approach 1:
The patent extracts only the essential directory information (chapter numbers, titles, and starting page numbers) from the full document structure, displaying them in a condensed list format. This extraction removes unnecessary details that would require scrolling, while preserving the critical document structure information needed for navigation, thereby improving ease of operation without losing structural context.

AI summary
The disclosure relates to a touch screen terminal and a method for locating an electronic document thereof. The touch screen terminal comprises a setting module, a directory listing module, a detection module, a mode switching module, a real-time directory module, a preview module and a chapter/section switching module. The method comprises: generating a directory listing for an electronic document and storing it; detecting a screen aaaaaaaaaaaaaaa in a reading mode of current chapter/section of the electronic document; when it is detected that a user enables a chapter/section switching function, enabling a chapter/section switching mode to wait for the user to input a number of the chapter/section to switch to; when it is detected that the user inputs the number of the chapter/section to switch to, matching a directory entry in real time from the stored directory listing and displaying it; generating a preview for a corresponding chapter/section according to the number of the chapter/section to switch to input by the user and displaying it to the user; and when a confirmation of the switching operation is detected, switching to the previewed chapter/section. The disclosure is simple to operate and easy to implement, and improves the reading experience.
