Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual cards are displayed as static pictures, then the display is simple and easy to implement, but the realism and user interaction are insufficient
Solution Approach 1:
The patent transforms the static card display into a dynamic one by introducing real-time parameter changes based on sensor data. The card's display features (position, size, transparency, rotation) are continuously updated according to sensor parameters collected from the mobile device, making the card respond dynamically to user actions and environmental changes.
Solution Approach 2:
The system implements feedback by collecting sensor parameters from the mobile device and using them to adjust the card's display features in real-time. The association relationship between sensor parameters and display features creates a closed-loop feedback mechanism where the card responds to user actions (such as device orientation, shaking, or tapping) and environmental conditions.
2Ease of operation
If static pictures are used for virtual cards, then the implementation is straightforward, but effective interaction with users cannot be performed
Solution Approach 1:
The card transitions from a static image to a dynamic object that changes its display features based on sensor input. The system maintains ease of implementation by using standard sensor APIs and display update mechanisms, while gaining enhanced user interaction capability through the dynamic response to sensor events.
Solution Approach 2:
The patent changes the display parameters of the card (position, size, transparency, rotation angle) based on sensor parameter changes. This allows the card to adapt to different user actions and environmental conditions while maintaining a consistent implementation framework.
3Adaptability or versatility
If real-time sensor data is used to dynamically change display features, then realism and interaction are enhanced, but data processing complexity increases
Solution Approach 1:
The system implements dynamic display feature changes by continuously monitoring sensor parameters and updating card properties in real-time. This creates an interactive experience where the card responds to user actions such as device orientation changes, shaking, or tapping, enhancing versatility while managing processing complexity through efficient event-driven updates.
Solution Approach 2:
The patent establishes association relationships between sensor parameters and display features, allowing automatic parameter changes without complex processing logic. When sensor parameters change, the corresponding display features are updated according to pre-defined associations, reducing the need for complex real-time decision-making algorithms.

AI summary
Techniques for displaying a virtual card are provided. The techniques comprise obtaining a first card face pattern, a first initial parameter, and a first association relationship corresponding to the virtual card, wherein the first initial parameter represents an initial parameter of a first display feature of a first material, and the first association relationship represents a rule by which a real-time parameter of the first display feature changes as a change of a parameter associated with a sensor in a mobile client device happens; displaying the first material in the virtual card based on the first initial parameter; detecting in real time the parameter associated with the sensor, and determining the real-time parameter of the first display feature based on the first association relationship and the parameter; and displaying the first material in the virtual card based on the real-time parameter of the first display feature.
