Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually zoom in on localized images by operating the phone, then the clarity of local details is improved, but the exercise experience deteriorates due to frequent operation disruptions
Solution Approach 1:
The system automatically detects user gaze direction through camera and sensor data, identifies regions of interest, and adjusts the display region without requiring manual user input. The processor autonomously determines when to zoom in or out based on detected joint positions and movement patterns, allowing the system to serve itself rather than requiring continuous user operation.
Solution Approach 2:
The system continuously monitors user motion through sensors and camera data, processes this feedback information to determine gaze direction and interest focus, and dynamically adjusts the display region in real-time. This closed-loop feedback mechanism enables automatic adaptation to user needs without interrupting the exercise flow.
2Ease of operation
If the display region is automatically adjusted based on motion detection, then the exercise experience is improved by reducing manual operations, but the device complexity increases due to motion detection and processing requirements
Solution Approach 1:
The system leverages existing multi-functional components (camera for both video capture and gaze detection, sensors for both fitness tracking and display control) to achieve automatic display adjustment. By making these existing components serve multiple purposes, the patent avoids adding dedicated complex hardware while still achieving the desired functionality.
Solution Approach 2:
The system uses audio content as an intermediary to bridge motion detection and display adjustment. Audio analysis provides additional context about the exercise demonstration, helping the processor make more accurate decisions about which regions to highlight, thereby simplifying the overall control logic while improving performance.
3Measurement precision
If multiple joints are monitored for display adjustment, then the accuracy of region identification is improved, but the processing time increases due to calculating scores for multiple joints
Solution Approach 1:
The system calculates displacement scores for multiple joints but applies different weighting and thresholds based on local characteristics. Different joints are monitored with different levels of intensity depending on their relevance to the current exercise phase, allowing accurate region identification while optimizing processing resources.
Solution Approach 2:
The system monitors multiple joints simultaneously (excessive action) but only triggers display adjustments when specific threshold conditions are met for relevant joints. This approach maintains high accuracy by considering multiple data points while avoiding unnecessary processing by only acting when conditions warrant intervention.

AI summary
An electronic device and a method for adjusting a display region based on motion are disclosed. The method includes: obtaining a first image including a first target object; detecting the first image to obtain a joint of the first target object; calculating a first score according to a first displacement of the first joint; in response to the first score being greater than a threshold, generating an adjustment command for adjusting a first display region of the first image according to the first joint; and outputting the adjustment command.
