Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for detecting operations on three-dimensional objects displayed in midair lack assurance of operability, as users may experience discomfort due to mismatched positional relationships between the detection device and the display, leading to incorrect operation detection.
Innovation Solution
A control device and method that dynamically adjust the positional relationship between the detection device and the display by setting a detection reference based on user-specific calibration, allowing for customizable detection reference positions to align with the user's perceived operation point, thereby enhancing operability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed detection reference position is used for detecting operations on midair display objects, then the device structure is simple, but user operability deteriorates due to mismatched positional relationships between different users
Solution Approach 1:
The detection reference position is made dynamic and adjustable rather than fixed. The system allows the detection reference position to be changed based on user-specific calibration, enabling the detection device to adapt to different users' operational preferences and anatomical differences, thereby improving operability without requiring a completely complex reconfiguration system
Solution Approach 2:
The positional parameter of the detection reference is made variable. By allowing the detection reference position to be adjusted along the depth direction based on user calibration data, the system optimizes the detection accuracy for each user while maintaining a relatively simple overall device structure
2Measurement precision
If the detection reference position is fixed relative to the display, then the device structure is simple, but measurement precision deteriorates due to incorrect operation detection
Solution Approach 1:
The system performs preliminary calibration before actual operation detection. By capturing user-specific operation data during a calibration phase and storing this information for subsequent use, the system ensures high measurement precision during actual operations without requiring complex real-time adjustment mechanisms
Solution Approach 2:
The system uses the user's own operation data to automatically determine the optimal detection reference position. During calibration, the system captures when the user actually performs operations and automatically sets the detection reference based on this self-provided data, eliminating the need for manual configuration or complex external calibration tools
3Ease of operation
If a customizable detection reference position is implemented, then user comfort is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The system automatically determines the detection reference position based on user calibration data without requiring manual intervention. The control unit automatically processes the captured operation data and adjusts the detection reference position, eliminating the need for complex manual control interfaces or additional hardware mechanisms
Solution Approach 2:
The system uses feedback from actual user operations during calibration to automatically adjust the detection reference position. By monitoring when users actually perform operations and using this feedback to optimize the detection parameters, the system achieves high user comfort with minimal additional control complexity
