Two-Dimensional Corner Indicators for Mobile Content Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current one-dimensional indication methods on mobile devices are inadequate for displaying large content pages, as they fail to provide a clear view of both horizontal and vertical scrolling, leading to user confusion and inefficient navigation.
Innovation Solution
A method and system for two-dimensional indication, where indicators are displayed at the four corners of the content display window, reflecting the size of the content outside the window, and dynamically change in response to user interactions, providing a comprehensive view of the content's extent in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional one-dimensional scroll bars are used for indication, then the indication method is simple to implement, but it fails to provide clear view of both horizontal and vertical scrolling for large content pages
Solution Approach 1:
The patent transitions from one-dimensional scroll bar indication to two-dimensional corner-based indication. Four indicators are placed at the corners of the content display window, each showing the extent of content outside the window in its corresponding direction. This dimensional change provides comprehensive horizontal and vertical scrolling information simultaneously, resolving the limitation of traditional scroll bars for large content pages.
2Loss of information
If four corner indicators are displayed to show content extent, then comprehensive two-dimensional indication is achieved, but more screen space is occupied compared to traditional scroll bars
Solution Approach 1:
Instead of using uniform scroll bar indicators, the patent places specialized indicators at specific locations (four corners) with specific functions. Each corner indicator locally represents the content extent in its corresponding direction, providing localized information that is immediately relevant to the user's viewing position without requiring centralized scroll bar space.
3Ease of operation
If indicators show the size of content outside the display window, then user understanding of content extent is improved, but the indication system becomes more complex to implement
Solution Approach 1:
The four corner indicators automatically update themselves based on the content display state. As the user scrolls or the content changes, each indicator dynamically reflects the current extent of content outside the display window in its corresponding direction, without requiring manual intervention or complex centralized control logic.

AI summary
This disclosure provides a method for two-dimensional indication in viewing contents. The method comprises in one embodiment displaying a content page in a content display window, wherein at least one of length and width of the content page exceeds the size of the content display window. The method further comprises in one embodiment displaying indicators located at four corners of the content display window, wherein each of the indicators indicates the size of part of the content page that is outside the corresponding corner of the content display window. The method further comprises in one embodiment in response to detecting a user operation that moves the content page relative to the content display window, changing each of the indicators to reflect the current size of part of the content page that is outside the corresponding corner of the content display window.
