Touch Panel Document Scrolling Segment Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for scrolling through a document on a touch panel require a large number of user manipulations to reach a desired page, lacking usability and efficiency.
Innovation Solution
A method and apparatus that display a segment on a touch panel with starting and end points corresponding to the first and last pages of a document, allowing users to scroll through pages by sliding a point perpendicular to the segment, enabling page-by-page navigation with minimal manipulations.

1Productivity
If a user manually pages through a multi-page document on a touch panel, then the document can be navigated, but a large number of manipulations are required which takes a long time
Solution Approach 1:
The system displays a thumbnail image of the entire document before the user begins scrolling, providing a preview of all pages. This preliminary visual information allows users to understand the document structure and plan their navigation, enabling them to reach the desired page more efficiently without manual page-by-page turning.
Solution Approach 2:
A thumbnail image serves as an intermediary between the user and the full document pages. Instead of directly navigating through each page, users interact with the thumbnail representation, which mediates the navigation process by providing an overview and enabling faster location of the desired page.
2Ease of operation
If a scrollbar is provided for document navigation, then page selection is enabled, but the interface complexity increases
Solution Approach 1:
The thumbnail image combines multiple functions into a single visual element: it serves as both a preview of the document content and a navigation control. Users can obtain an overview of the document structure while simultaneously using the thumbnail as the scrolling interface, eliminating the need for separate scrollbars or navigation buttons.
Solution Approach 2:
The thumbnail image performs multiple functions simultaneously - it provides visual preview information about the document content, indicates the current position in the document, and serves as the interactive scrolling mechanism. This multi-functionality reduces the overall complexity of the interface by consolidating navigation elements.

AI summary
In one embodiment, a computer-implemented method includes displaying a segment on a touch panel, the segment having a starting point and an end point corresponding to a first page and a last page, respectively, of a document, in response to a predetermined manipulation by a user. An indication is received that the user has performed at least one of touching a point on the segment and sliding a point on the segment. The document is scrolled to reach a page corresponding to the position of the point on the segment, in response to the indication. The document is scrolled, by a computer processor, on a page-by-page basis, in response to the user sliding the point in a direction perpendicular to the segment.
