Engineering Contradiction Analysis
1Measurement precision
If traditional gross and disassociated means are used for user interaction in 3D display systems, then device complexity is reduced, but measurement precision and user experience are degraded
Solution Approach 1:
The patent combines multiple tracking sensors (cameras, infrared sensors, or other detection devices) into an integrated tracking system that simultaneously captures user view position, orientation, and control device position. This merging of multiple sensing functions into a unified system achieves high-precision tracking without proportionally increasing overall system complexity.
Solution Approach 2:
The tracking sensors are designed to perform multiple functions: detecting user head position, determining user orientation, and tracking control device location within the same system architecture. This multi-functionality allows the system to achieve comprehensive measurement precision using a unified sensing approach rather than separate dedicated sensors for each parameter.
2Measurement precision
If tracking sensors are added to sense user view and control position information, then measurement precision improves, but device complexity increases
Solution Approach 1:
The tracking system is segmented into distinct functional modules: sensors for detecting user view position, sensors for determining orientation, and sensors for tracking control device position. Each module can be independently calibrated and optimized, which manages complexity while maintaining high measurement precision for each specific parameter.
Solution Approach 2:
The system continuously receives feedback from tracking sensors about user position and orientation, and uses this feedback to dynamically adjust the rendered image perspective and control device positioning. This closed-loop feedback mechanism ensures high measurement precision is maintained and utilized effectively, justifying the added sensor complexity.
3Reliability
If dynamically updated rendered images are generated based on tracking values, then realism and user experience improve, but processing speed and energy consumption increase
Solution Approach 1:
The system dynamically updates only the portions of the rendered image that are affected by changes in user position or orientation, rather than completely re-rendering the entire scene. This partial action approach maintains high 3D image accuracy and realism while significantly reducing the processing power and energy consumption required compared to full scene re-rendering.
Solution Approach 2:
The system performs dynamic image updates at periodic intervals based on changes in tracking values, rather than continuously rendering at maximum rate. This periodic action maintains visual realism and accuracy during user interaction while allowing processing load to be managed in discrete bursts, reducing overall energy consumption.
