Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional game controllers are used for VR interaction, then device complexity is reduced, but measurement precision of hand pose and orientation is insufficient
Solution Approach 1:
The patent combines multiple sensor types (accelerometers, gyroscopes, magnetometers, touch sensors) and lighting elements into a single integrated interface object unit. This merging approach enables comprehensive hand pose and orientation detection while maintaining a unified device structure that can be easily held and manipulated by the user.
Solution Approach 2:
The interface object is designed to perform multiple functions simultaneously: tracking hand position in 3D space, detecting orientation through inertial sensors, capturing touch input from multiple surface locations, and providing visual feedback through lights. This multi-functionality resolves the contradiction by achieving high measurement precision without requiring multiple separate devices.
2Measurement precision
If multiple sensors and lights are integrated into the interface object, then hand tracking accuracy is improved, but device complexity increases
Solution Approach 1:
The interface object divides its sensing capabilities into distinct functional segments: inertial measurement units for orientation, touch sensors distributed across surfaces for contact detection, and lights for visual feedback. This segmentation allows each component to be optimized independently while working together as a cohesive system for accurate hand tracking.
3Measurement precision
If the interface object detects which hand is holding it, then virtual hand correspondence is improved, but ease of operation is reduced
Solution Approach 1:
The interface object automatically performs hand identification without requiring user input. The touch sensors detect which hand is holding the device based on contact patterns and orientation, and the system autonomously determines left or right hand configuration. This self-service approach resolves the contradiction by achieving accurate hand identification while maintaining ease of operation.
