Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual user interfaces operate in three-dimensional space, then they provide immersive interaction experience, but they cause user fatigue and ergonomic inefficiency
Solution Approach 1:
The patent transitions the interaction space from three-dimensional to two-dimensional by projecting the interaction plane onto a flat surface. This dimensionality reduction eliminates the ergonomic problems associated with 3D space while maintaining rich interaction capabilities through the 2D plane, directly resolving the contradiction between immersive experience and user fatigue.
2Reliability
If virtual user interfaces interpret gestures in three-dimensional space, then they enable natural interaction, but they lead to computational difficulty and gesture misinterpretation
Solution Approach 1:
By constraining gesture recognition to a two-dimensional interaction plane, the system dramatically reduces computational complexity compared to full 3D gesture interpretation. The 2D plane provides sufficient information for accurate gesture recognition while avoiding the computational burden and misinterpretation issues inherent in 3D space, thus resolving the reliability-complexity contradiction.
Solution Approach 2:
The patent extracts the essential interaction elements from three-dimensional space and concentrates them onto a two-dimensional plane. This extraction process removes the unnecessary computational complexity of 3D gesture interpretation while preserving the core interaction capabilities, thereby improving gesture interpretation accuracy without proportional increases in computational demand.
3Adaptability or versatility
If a single interaction mode is used for the entire plane, then the system is simple to manage, but it lacks adaptability to different interaction needs in different regions
Solution Approach 1:
The patent divides the interaction plane into multiple independent regions, each capable of having its own interaction mode. This segmentation allows different parts of the plane to be optimized for different interaction needs (e.g., drawing, text input, navigation) simultaneously, providing high adaptability while keeping each region's management simple and modular.
Solution Approach 2:
The system implements local quality by allowing different interaction modes in different regions of the plane. Each region can be independently configured with the interaction mode most suitable for its specific function, thereby achieving high versatility without requiring complex global management, as each region operates independently with its own optimized settings.
