Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces for augmented and virtual reality lack intuitive and adaptive control methods for managing virtual windows, limiting user interaction and immersion in these environments.
Innovation Solution
A 3D window management method that uses hand gesture recognition to control virtual windows, allowing users to select, move, scale, and place them based on hand and finger positions, with a sensor and controller system to implement these controls in augmented and virtual reality environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 2D window management interfaces are used in AR/VR environments, then the system structure remains simple, but user interaction intuitiveness and immersion are reduced
Solution Approach 1:
The patent transitions from traditional 2D window management to 3D spatial window management in AR/VR environments. Virtual windows are positioned and manipulated in three-dimensional space using hand gestures, allowing users to interact with windows floating in 3D space rather than confined to a 2D screen, thereby enhancing immersion and intuitiveness
Solution Approach 2:
The patent replaces traditional mechanical input devices (mouse, keyboard) with hand gesture recognition. The system captures hand positions and finger configurations through sensors and translates them into window management commands, substituting physical mechanical interaction with spatial gesture-based control
2Ease of operation
If hand gesture recognition is implemented for window control, then user immersion is enhanced, but control precision and reliability may be reduced
Solution Approach 1:
The patent employs different hand gestures for different window management functions: pinching with thumb and index finger for selection, spreading fingers for movement, and specific finger configurations for scaling. Each gesture type is optimized for its specific function, providing reliable and intuitive control for each operation
Solution Approach 2:
The system provides visual feedback by displaying cursors and highlighting windows in response to hand gestures. The cursor position follows the hand movement, and selected windows are visually indicated, allowing users to verify gesture recognition and control actions in real-time, thereby enhancing precision and reliability
3Adaptability or versatility
If virtual windows are allowed to move freely in 3D space, then user flexibility is improved, but system complexity and computational requirements increase
Solution Approach 1:
The patent implements dynamic window positioning where virtual windows can be freely moved to any location in the 3D space by the user through hand gestures. The system dynamically updates window positions, orientations, and sizes based on continuous gesture input, providing high adaptability while managing computational complexity through efficient rendering
