Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware controllers are used for large-sized display devices, then device control functionality is provided, but security issues arise and user convenience deteriorates due to unauthorized access
Solution Approach 1:
The patent replaces the mechanical hardware controller system with an optical recognition system using cameras and image processing. The control device captures images of user faces and gestures, processes them through algorithms, and translates them into control commands, eliminating the need for physical controllers and enabling contactless operation.
Solution Approach 2:
The patent creates a digital copy of the user's identity through face recognition technology. By capturing and processing facial features, the system generates a unique digital identifier that authenticates the user, replacing the need for physical authentication devices and enabling secure, convenient access.
2Adaptability or versatility
If hardware controllers are used for display devices, then control functionality is provided, but device complexity increases and costs rise
Solution Approach 1:
The patent implements a universal control system that can identify and authenticate multiple different users through face recognition. The same system infrastructure serves all users, providing personalized control experiences without requiring separate hardware for each user, thereby reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The patent extracts the authentication and control functions from dedicated hardware controllers and relocates them to a software-based image processing system. This separation allows the control functionality to be implemented through algorithms and data processing rather than specialized hardware, reducing device complexity.
3Ease of operation
If face and gesture recognition are implemented, then contactless control is enabled and security is improved, but system complexity increases
Solution Approach 1:
The patent merges face recognition and gesture recognition into a unified control system. Both recognition functions share common infrastructure including image capture, preprocessing, and command generation modules. This integration reduces redundant components and simplifies the overall system architecture while providing comprehensive contactless control capabilities.

AI summary
Provided is a control method including obtaining a first image; performing face recognition and gesture recognition on the first image; turning on a gesture control function when a first target face is recognized from the first image and a first target gesture is recognized from the first image; and returning to the act of obtaining the first image when the first target face is not recognized from the first image or the first target gesture is not recognized from the first image.
