Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If powerful processors are used to track complex movements and display augmented reality content, then measurement precision and reliability are improved, but use of energy increases and device weight increases
Solution Approach 1:
The system divides the augmented reality processing workload between a first device (e.g., smartphone) and a second device (e.g., AR headset). The first device handles complex feature analysis and processing tasks, while the second device handles display and tracking. This segmentation allows each device to use processors appropriate to its function, reducing overall power consumption while maintaining tracking precision.
2Measurement precision
If powerful processors are used to track complex movements and display augmented reality content, then measurement precision and reliability are improved, but weight of moving object increases
Solution Approach 1:
The system divides the augmented reality processing workload between a first device (e.g., smartphone) and a second device (e.g., AR headset). The first device handles complex feature analysis and processing tasks, while the second device handles display and tracking. This segmentation allows each device to use processors appropriate to its function, reducing overall power consumption while maintaining tracking precision.
3Duration of action of moving object
If large batteries are included to extend battery life, then duration of action is improved, but weight of moving object increases
Solution Approach 1:
The system divides the augmented reality processing workload between a first device (e.g., smartphone) and a second device (e.g., AR headset). The first device handles complex feature analysis and processing tasks, while the second device handles display and tracking. This segmentation allows each device to use processors appropriate to its function, reducing overall power consumption while maintaining tracking precision.
4Device complexity
If processing tasks are concentrated on a single device, then device complexity is reduced, but use of energy increases
Solution Approach 1:
The system divides the augmented reality processing workload between a first device (e.g., smartphone) and a second device (e.g., AR headset). The first device handles complex feature analysis and processing tasks, while the second device handles display and tracking. This segmentation allows each device to use processors appropriate to its function, reducing overall power consumption while maintaining tracking precision.
Solution Approach 2:
The system enables two different devices to work together in an augmented reality setup, where each device can be used for its primary function while also contributing to the shared AR experience. This multi-functionality approach distributes processing loads and reduces the energy requirements of each individual device.

AI summary
Systems and techniques for displaying augmented reality enhanced media content are disclosed. For instance, a process can include displaying media content on one or more displays. The process can include: generating a first media content element for an application engine associated with an application state of the application engine; generating a second media content element for the application engine associated with the application state of the application engine; displaying, on a first display of a first device, the first media content element; and outputting the second media content element for display on a second display of a second device relative to a pose of the first display of the first device.
