Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If visual gesture input devices are used for computing systems, then user interaction capability is improved, but tracking precision deteriorates when objects are partially blocked
Solution Approach 1:
The patent introduces an intermediary tracking system that uses multiple cameras and sophisticated image processing algorithms to overcome the limitation of single-camera tracking. The multi-camera setup acts as an intermediary that captures objects from multiple angles simultaneously, preventing blocking issues and maintaining tracking precision even when objects are partially obscured from any single viewpoint.
Solution Approach 2:
The patent transitions from two-dimensional single-camera tracking to three-dimensional multi-camera tracking. By adding spatial dimensions through multiple camera viewpoints, the system can reconstruct object positions and trajectories in 3D space, eliminating the blocking problem inherent in single-plane tracking and significantly improving measurement precision.
2Adaptability or versatility
If wearable gesture gloves are used for input, then interaction flexibility is improved, but user convenience deteriorates due to continuous removal and putting on
Solution Approach 1:
The patent extracts the tracking function from wearable gloves and relocates it to the environment through fixed cameras. By taking out the tracking capability from the user's body and placing it in the surrounding environment, the system maintains interaction flexibility through gesture recognition while eliminating the inconvenience of wearing and removing gloves.
Solution Approach 2:
The patent enables the tracking system to serve itself by using environmental cameras and automated image processing rather than requiring user attachment of wearable devices. The system automatically detects and tracks gestures in the field of view, providing hands-free operation that improves user convenience while maintaining interaction flexibility.
3Device complexity
If single-camera tracking is used, then device complexity is reduced, but tracking reliability deteriorates when objects are blocked
Solution Approach 1:
The patent segments the tracking function across multiple independent camera units rather than relying on a single complex camera system. Each camera independently tracks objects from its own viewpoint, and the system integrates these segmented tracking data streams to produce reliable overall tracking results, preventing single-point failures when objects are blocked from any single view.
