Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a general infotainment system requires multiple touch inputs and precise positioning to perform functions, then the system can accurately identify user intent, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The system performs preliminary classification of touch inputs by analyzing the spatial relationship between multiple touch points. When two touch points are detected within a predetermined distance, the system pre-identifies this as a specific gesture pattern (e.g., pinch-to-zoom or two-finger scroll) and directly maps it to the corresponding function, eliminating the need for sequential hierarchical menu navigation and reducing the number of required touch operations.
Solution Approach 2:
The system transitions from traditional single-point touch recognition to multi-dimensional touch pattern recognition by considering the relative positions, distances, and geometric relationships between multiple touch points simultaneously. This dimensional expansion enables the system to distinguish between different user intentions based on touch configuration rather than requiring multiple sequential touches, thereby improving both precision and ease of operation.
2Manufacturing precision
If the infotainment system requires multiple hierarchical touch inputs to adjust functions, then the system can precisely control function parameters, but the time required for operation increases
Solution Approach 1:
The system merges multiple discrete touch operations into a single composite gesture recognition event. By combining the detection of multiple touch points and their spatial relationships into one unified input event, the system can directly determine the desired function adjustment (e.g., temperature change, volume adjustment) without requiring the user to navigate through hierarchical menus, thereby reducing operation time while maintaining control precision.
Solution Approach 2:
The system creates a virtual model of the user's touch pattern by analyzing the geometric configuration of multiple touch points. This virtual representation is then matched against predefined gesture templates to quickly identify the intended function, enabling rapid response without sequential processing steps and reducing the time from input to function execution.
3Measurement precision
If the touch screen requires precise targeting of display areas to perform functions, then the system can accurately execute user commands, but the device complexity increases
Solution Approach 1:
The system applies different recognition rules to different spatial configurations of touch points rather than requiring precise targeting of specific display areas. By analyzing the local geometric relationships between touch points (such as distance thresholds and relative positioning), the system can identify gestures and execute corresponding functions without requiring the user to precisely target specific UI elements, thereby reducing system complexity while maintaining execution accuracy.

AI summary
An electronic device mounted in a vehicle, and an method performed thereby are provided. The electronic device may include a touch screen, memory storing at least one instruction, and at least one processor communicatively coupled to the touch screen and the memory. The at least one instruction, when executed by the at least one processor individually or collectively, may cause the electronic device to recognize an input event, based on receiving a multi-touch input or a hover input, of a user with respect to the touch screen, may identify a function corresponding to the input event, based on shape information of a plurality of points and position information of the plurality of points at which the input event is recognized, may change a function value with respect to the identified function, based on a gesture input being recognized via the touch screen, and may display a user interface (UI) indicating the changed function value.
