Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed input interface with standard touch areas is provided, then the device structure remains simple and easy to manufacture, but users with different finger lengths and usage habits cannot accurately touch the correct areas, reducing operation accuracy
Solution Approach 1:
The patent applies dynamics by making the touch areas adjustable and adaptable rather than fixed. The system dynamically adjusts touch area positions and sizes based on individual user characteristics detected during operation, allowing the input interface to evolve and optimize for each user's specific needs, thereby improving touch accuracy without requiring complex hardware modifications
Solution Approach 2:
The patent changes the parameters of touch areas (position, size, shape) based on user-specific data. By collecting and analyzing user touch patterns, the system modifies touch area parameters to match individual finger lengths and usage habits, resolving the contradiction between maintaining simple structure and achieving high precision for diverse users
2Measurement precision
If the input interface is customized for each user, then touch operation accuracy improves, but the time required for initial setup and calibration increases
Solution Approach 1:
The patent applies preliminary action by performing touch area calibration during the initial device setup phase. By completing the user-specific customization process beforehand, the system establishes accurate touch areas for each user before normal operation begins, ensuring high touch accuracy without requiring time-consuming adjustments during actual use
Solution Approach 2:
The system performs self-calibration by automatically analyzing user touch patterns and adjusting touch areas without requiring manual intervention. The device serves itself by detecting usage habits and optimizing touch zone configurations autonomously, reducing both setup time and user burden while maintaining high accuracy

AI summary
A virtual image display device and a setting method for an input interface are provided. The virtual image display device includes a virtual image display and a handheld electronic device. The virtual image display executes an application to provide multiple prompt commands to perform a setting action of the input interface. The handheld electronic device displays the input interface and receives multiple input touch actions corresponding to each of the prompt commands through the input interface in the setting action. The virtual image display calculates multiple effective touch areas respectively corresponding to the prompt commands according to a position distribution of each input touch action corresponding to each of the prompt commands.
