Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine-learning algorithms are used for object recognition, then identification accuracy is improved, but computational intensity increases
Solution Approach 1:
The system performs preliminary actions by pre-processing images to identify and extract candidate object regions before applying computationally intensive machine-learning algorithms. This preliminary segmentation reduces the amount of data that requires full computational analysis, thereby maintaining high identification accuracy while reducing overall computational intensity and energy consumption.
2Ease of operation
If portable devices are used for object recognition, then accessibility and convenience are improved, but computational resources are limited
Solution Approach 1:
The object recognition system segments the image processing task into multiple stages: initial filtering, candidate region identification, and detailed analysis. By dividing the computational workload in this manner, the system can run on portable devices with limited resources while still achieving accurate recognition results through progressive refinement of candidate objects.
3Measurement precision
If user training is provided for optimal image capturing, then recognition accuracy is improved, but time required for learning increases
Solution Approach 1:
The tutoring application implements feedback mechanisms that provide real-time guidance to users during the image capturing process. The system analyzes captured images and provides immediate feedback on positioning, framing, and quality metrics, allowing users to learn optimal capturing techniques through guided practice rather than lengthy theoretical training, thus reducing training time while maintaining accuracy improvement.
Data Source
AI summary
A device including a storage medium storing instructions, and at least one processor configured to execute the stored instructions to perform operations is provided. The operations include displaying on a display screen an interactive scene containing an augmented reality element, receiving input to change display of the interactive scene, and receiving a request to simulate the capturing of image data representing the interactive scene. The operations further include determining a position of the augmented reality element relative to a region defined on the display screen, simulating the capturing of the image data representing the interactive scene, and providing, based on the determined position, an indication of whether the simulation has succeeded.
