3D Navigation System With Segmented GUI Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D navigation systems are difficult for both novice and experienced users to operate effectively, as they lack intuitive tools for navigating three-dimensional scenes without horizontal displacement, making it hard to manage view positioning within a scene.
Innovation Solution
A navigation system with graphical user interface (GUI) wheels and corresponding miniature or pie menu versions that allow users to interactively navigate 3D scenes by using tools like orbit, zoom, rewind, and up/down tools, providing visual feedback and constraints to prevent errors, and allowing rapid access to navigation tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 3D navigation controls are used, then users can navigate the scene, but the operation becomes difficult and error-prone for both novice and experienced users
Solution Approach 1:
The navigation system is segmented into distinct functional wheels (orbit wheel, zoom wheel, pan wheel, up/down wheel) that can be independently activated. Each wheel handles a specific navigation task, reducing cognitive load and preventing accidental activation of unintended navigation functions. This segmentation allows users to focus on one navigation dimension at a time, improving both ease of operation and navigation accuracy.
Solution Approach 2:
The system dynamically switches between different navigation modes based on user interaction. When a wheel is activated, it becomes the active navigation tool; when deactivated, control returns to the previous state. This dynamic behavior allows the system to adapt to user needs while maintaining predictable control, reducing errors from unintended navigation actions.
2Ease of operation
If users can move up and down in the scene freely, then vertical navigation is improved, but horizontal displacement occurs which disrupts the user's view positioning
Solution Approach 1:
The up/down wheel is separated from other navigation controls, dedicating it exclusively to vertical movement along the scene's up axis. This segmentation ensures that vertical navigation can be performed independently without affecting horizontal position, allowing users to move up and down while maintaining precise control over their horizontal view positioning.
Solution Approach 2:
The up/down wheel operates in the vertical dimension (Y-axis) independently from horizontal movements (X and Z axes). By isolating vertical navigation to its own control dimension, the system allows free vertical movement without causing unwanted horizontal displacement, effectively adding an independent degree of freedom to the navigation system.
3Adaptability or versatility
If comprehensive navigation tools are provided, then navigation capability is enhanced, but the system complexity increases making it harder to use
Solution Approach 1:
Each navigation wheel serves multiple functions within its domain. For example, the orbit wheel handles both horizontal rotation and vertical tilt, while the zoom wheel manages both zoom in and zoom out operations. This multi-functionality within each wheel reduces the total number of separate controls needed, maintaining comprehensive navigation capability while reducing overall system complexity.
Solution Approach 2:
The comprehensive navigation system is divided into specialized wheels, each handling a specific aspect of navigation. This segmentation makes the complex system more manageable by allowing users to learn and use one wheel at a time rather than memorizing a single complex control interface. Each wheel's dedicated function reduces cognitive load while collectively providing comprehensive navigation capability.
4Loss of information
If visual feedback is provided during navigation, then user awareness of position is improved, but the interface becomes more complex
Solution Approach 1:
The system provides visual feedback through the active wheel indicator and position markers that show users which navigation mode is active and what their current position is within the scene. This feedback mechanism maintains position awareness without requiring complex additional interfaces, as the feedback is integrated into the existing wheel-based control system.
Solution Approach 2:
The active wheel is highlighted with visual indicators (such as color changes or brightness adjustments) to provide immediate feedback about which navigation tool is currently active. This simple visual cue system enhances position awareness and control state understanding without adding complex interface elements, maintaining clarity while improving user awareness.

AI summary
A navigation system for navigating a three-dimensional (3D) scene that includes a model or object with which a user can interact. The system accommodates and helps both novice and advanced users. To do this, the system allows a user to move up and down within a scene relative to an up axis of the scene without the user being displaced horizontally. A scale is provided that shows the user the relative position of the current view in the vertical bounding box of the scene.
