Keyboard Terminal Directory Listing for Electronic Document Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locating chapters and sections in electronic documents on mobile terminals are inefficient and inaccurate, requiring repetitive key presses or bookmark management, which hampers user experience.
Innovation Solution
A keyboard-type terminal with a location method that generates a directory listing for electronic documents, allowing users to input chapter and section numbers for immediate matching and preview, enabling direct switching without bookmarks or directory browsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If directory browsing is used to locate chapters and sections, then users can navigate through the document structure, but the operation becomes time-consuming and inefficient when chapters are far apart
Solution Approach 1:
The system pre-generates and stores a directory listing containing all chapter and section information before the user needs to navigate. When a user wants to jump to a specific chapter, the matching is performed immediately against this pre-prepared directory, eliminating the need for sequential browsing and enabling direct access to any chapter.
Solution Approach 2:
Instead of requiring users to physically browse through the entire document or directory structure, the system creates a simplified copy of the directory information in memory and performs matching operations on this copy. This allows rapid comparison of user input against all directory entries without accessing the actual document content, significantly reducing navigation time.
2Productivity
If bookmarks are used to store document positions, then users can quickly jump to saved locations, but the system becomes complex and requires managing multiple bookmarks
Solution Approach 1:
The invention extracts only the essential navigation information (chapter and section numbers) from the full document structure and stores it in a simplified directory listing. Users input only the chapter and section numbers they want to access, and the system performs direct matching without requiring users to manage or remember multiple bookmark entries, thus simplifying the navigation process while maintaining efficiency.
Solution Approach 2:
The system automatically generates and maintains the directory listing structure, and automatically performs the matching operation when users input chapter and section numbers. Users simply need to input their desired location, and the system handles all the complexity of searching and locating the position, making the navigation process self-service and eliminating the need for manual bookmark management.
3Measurement precision
If text fragment bookmarks are used for location, then users can identify bookmark positions through displayed text, but accurate location becomes difficult when text fragments are not distinctive or when many bookmarks exist
Solution Approach 1:
The system changes the parameter used for bookmark identification from text fragments to structured chapter and section numbers. Instead of relying on users to recognize and select bookmarks based on displayed text snippets, users input numerical identifiers (chapter number and section number) that directly correspond to the document structure, enabling precise and unambiguous location identification regardless of the number of bookmarks or the distinctiveness of text fragments.

AI summary
A keyboard type terminal and a location method for electronic document therein are disclosed. The keyboard type terminal includes a setting module, a directory listing module, a detection module, a real-time directory module, a preview module and a chapter and section switchover module. The method includes: a directory listing is generated for an electronic document and the directory listing is stored; a keyboard input is detected under a reading interface of a current chapter and section of the electronic document; in response to a to-be-switched chapter and section number inputted from a user, the to-be-switched chapter and section number is immediately matched with directory entries in the stored directory listing, and the matched directory entry is displayed; a preview of a chapter and section corresponding to the to-be-switched chapter and section number is generated according to the to-be-switched chapter and section number inputted by the user, and the preview of the chapter and section is displayed to the user; and in response to a confirmation of switching to the chapter and section from the user, the previewed section is switched to. The disclosure is easy to use and implement, and improves the reading experience.
