Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing AR systems are implemented, then augmented reality functionality is achieved, but device complexity and cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling standard mobile devices with existing cameras, processors, and displays to perform AR functions without requiring specialized hardware. The system uses the device's built-in video camera, motion sensors, and display screen to achieve AR capabilities that were previously only available in complex dedicated AR systems
Solution Approach 2:
The patent uses copying by creating a virtual information layer that overlays computer-generated imagery onto the real-world view captured by the device camera. This allows the system to replicate complex AR visualizations using software-based image processing and display composition rather than requiring specialized optical hardware
2Adaptability or versatility
If existing AR systems are implemented, then augmented reality functionality is achieved, but cost increases
Solution Approach 1:
The patent enables AR functionality on standard mobile devices that consumers already own, eliminating the need to manufacture and distribute expensive dedicated AR hardware. By utilizing existing device components (camera, processor, display, motion sensors), the system achieves AR capabilities at zero additional hardware cost for the end user
Solution Approach 2:
The patent employs software-based AR solutions that can be distributed digitally and updated remotely, replacing the need for expensive physical AR hardware. The virtual information layer and processing algorithms can be delivered as software updates, making the system economically accessible to consumers
3Reliability
If motion sensors are used for synchronization, then AR display synchronization is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by utilizing motion sensors that are already built into standard mobile devices for AR synchronization purposes. The system repurposes existing device components (accelerometers, gyroscopes) to track device motion and synchronize the virtual information layer with the user's perspective, eliminating the need for additional specialized sensors
Data Source
AI summary
A device can receive live video of a real-world, physical environment on a touch sensitive surface. One or more objects can be identified in the live video. An information layer can be generated related to the objects. In some implementations, the information layer can include annotations made by a user through the touch sensitive surface. The information layer and live video can be combined in a display of the device. Data can be received from one or more onboard sensors indicating that the device is in motion. The sensor data can be used to synchronize the live video and the information layer as the perspective of video camera view changes due to the motion. The live video and information layer can be shared with other devices over a communication link.
