Solution Overview
Problem
Current gesture control systems for display screens are limited to a fixed detection area, restricting user interaction and leading to poorer performance when control operations are performed outside this area.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single gesture detection module is installed at a certain location of the display screen, then the device complexity is reduced, but the gesture control performance deteriorates when users perform control operations outside the fixed detection area
Solution Approach 1:
The display screen is divided into multiple detection zones, each covered by a separate gesture detection module. Multiple modules are distributed across the display screen surface, with each module responsible for detecting gestures within its specific detection area. This segmentation allows the system to cover the entire display screen while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The gesture detection modules use a unified detection algorithm and coordinate transformation mechanism that works across all detection areas. The same processing unit handles data from any module, and the coordinate transformation system universally maps any module's coordinate system to the standard coordinate system, making the system multi-functional across the entire display screen.
2Reliability
If multiple gesture detection modules are installed to cover various directions of the display screen, then the gesture control performance is improved, but the device complexity increases
Solution Approach 1:
Multiple gesture detection modules are merged into a unified detection system through coordinate transformation. Each module's detection data is transformed into a standard coordinate system, allowing the system to process gestures from any location as if detected by a single reference module. This merging approach maintains high gesture control performance while managing system complexity through unified processing.
Solution Approach 2:
A coordinate transformation mechanism acts as an intermediary between different gesture detection modules and the control system. The transformation matrix converts coordinates from any module's local coordinate system to the standard coordinate system, enabling seamless integration of multiple modules without requiring complex direct communication between them.
3Device complexity
If gesture control is limited to a fixed detection area, then the device complexity is reduced, but the adaptability deteriorates when users need to control the display screen beyond this area
Solution Approach 1:
The system extends detection capability from a two-dimensional fixed area to the entire display screen surface by adding multiple detection modules distributed across different locations. This spatial dimensionality expansion allows gestures to be detected anywhere on the screen while maintaining systematic processing through coordinate transformation.
4Adaptability or versatility
If multiple gesture detection modules with different coordinate systems are used, then the gesture control range is expanded, but the data processing complexity increases
Solution Approach 1:
The system uses parameter transformation through coordinate transformation matrices to convert detection data from different coordinate systems into a unified standard coordinate system. This parameter change approach allows the system to handle data from multiple modules with different coordinate systems while maintaining consistent processing and control.
