Radially Expanding Navigation Dial for Context-Sensitive Menu Hierarchy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional menu bar techniques require users to shift focus from application content to the menu bar for selection, leading to difficulties in remembering prior focus, repetitive strain, and inefficient use of window space, as well as challenges in navigating and precisely selecting menu items within drop-down lists.
Innovation Solution
A menu system that displays menus as a navigation dial, a circular area with menu items near the perimeter, allowing for radial expansion of sub-items and scrolling, enabling users to select menu items with increased ease and context-sensitive display near relevant content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu bar techniques are used, then menu items can be displayed in a hierarchical structure, but users experience repetitive strain and attention shifts when moving from content to the menu bar
Solution Approach 1:
The patent transforms the traditional linear horizontal menu bar into a circular navigation dial interface. This dimensional change from linear to circular arrangement allows menu items to be organized radially around a central point, enabling users to access menu items in a more natural rotational motion rather than linear scanning, thereby reducing attention shifts and repetitive strain.
Solution Approach 2:
The patent employs a circular/spherical geometric form for the navigation dial, where menu items are arranged along the circumference. This curved arrangement naturally guides user attention in a rotational pattern, reducing the cognitive load and physical strain associated with scanning linear menu bars, while maintaining hierarchical organization through radial depth.
2Area of stationary object
If traditional menu bar techniques are used, then menu hierarchy can be displayed, but valuable window space is consumed that could be used for application content
Solution Approach 1:
The patent implements a nested hierarchical structure where menu sub-items are organized in concentric circular layers around the main menu items. This nesting approach allows multiple levels of menu hierarchy to be compactly arranged within a small radial space, minimizing the overall area occupied by the menu interface while maintaining full hierarchical functionality.
Solution Approach 2:
The patent transitions from a two-dimensional linear menu bar to a radial/circular interface that utilizes angular and radial dimensions. This dimensional transformation allows hierarchical menu structures to be packed more efficiently into a compact circular footprint, significantly reducing the linear space consumption compared to traditional horizontal menu bars while preserving the complete menu hierarchy.
3Ease of operation
If drop-down lists are used for menu sub-items, then menu hierarchy can be expanded, but it becomes difficult to precisely select menu items without inadvertent selection
Solution Approach 1:
The patent uses a circular arrangement where menu items are positioned along the circumference of the navigation dial. This curved geometric arrangement provides naturally larger and more evenly spaced target areas compared to compact drop-down lists, making it easier for users to accurately position their mouse pointers and select the intended menu item without inadvertently triggering adjacent items.
Solution Approach 2:
The patent segments the menu interface into distinct radial zones and angular sectors, with each menu item occupying a well-defined angular position on the circular dial. This segmentation creates clear visual and spatial boundaries between adjacent menu items, reducing the likelihood of inadvertent selection and improving positioning accuracy.

AI summary
A method and system for displaying menus of menu items as a navigation dial is provided. A menu system provides a menu hierarchy for an application that includes menu items with menu sub-items and displays the menu items in a navigation dial. The menu hierarchy is dependent on the current context of the application. A navigation dial is a circular area in which the menu items are displayed near the perimeter of the area. When a user selects a menu item with menu sub-items, the menu system creates a radially expanding navigation dial and populates it with the menu sub-items. The radially expanding navigation dial is displayed outside the perimeter of the displayed navigation dial near the selected menu item.
