Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple sensors are used in augmented reality systems to capture real-world scenes, then the system can provide rich visual information, but registration problems occur due to different sensor speeds causing misalignment between computer graphics and real-world scene
Solution Approach 1:
A camera serves as an intermediary device to capture the real-world scene, replacing multiple sensors with a single imaging device. The camera captures complete visual information in one shot, eliminating the registration problems that arise from multiple sensors operating at different speeds. The captured image becomes the common reference frame for all subsequent processing.
Solution Approach 2:
Multiple sensor functions are merged into a single camera system. Instead of using separate sensors for different measurements that require synchronization, the patent combines all visual capture functions into one camera that records the entire scene simultaneously, ensuring all visual information is captured without registration issues.
2Measurement precision
If head tracking systems and cameras are used together in augmented reality systems, then spatial alignment can be achieved, but delays in merging computer graphics with real-world scene cause misalignment and user discomfort
Solution Approach 1:
The camera captures the complete real-world scene in advance before any processing occurs. By pre-capturing the entire scene as a single image or video frame, the system eliminates the need for continuous synchronization and merging operations that cause delays. The pre-captured image serves as the fixed reference for all augmented reality operations.
Solution Approach 2:
The patent extracts the scene capture function from the complex head tracking system and assigns it to a dedicated camera. This separation removes the camera from the real-time processing chain, eliminating the delays that occur when the camera must continuously synchronize with the head tracking system. The camera operates independently, capturing scenes without being constrained by processing delays.
3Adaptability or versatility
If complex augmented reality systems with multiple sensors and processing components are implemented, then enhanced reality features can be provided, but the systems become non-portable and unsuitable for consumer applications
Solution Approach 1:
The camera serves multiple functions: capturing the real-world scene, providing reference images for augmented reality overlay, and enabling portable operation. By making the camera a universal component that performs all scene capture needs, the system eliminates the need for multiple specialized sensors and processing units, thereby reducing overall system complexity while maintaining augmented reality functionality.
