Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional interface operations are used to trigger projection, then projection can be achieved, but the operation process becomes complex and efficiency decreases
Solution Approach 1:
The patent replaces the mechanical interface operation system (manual navigation through settings menus, device connection options, and projection settings) with an optical gesture recognition system. The camera captures hand gestures, and the system automatically triggers projection based on recognized gesture patterns, eliminating the need for multi-step interface interactions and significantly reducing operation time.
2Ease of operation
If gesture recognition is implemented, then projection operation becomes simpler, but device complexity increases due to camera and gesture processing requirements
Solution Approach 1:
The patent leverages the existing camera module in mobile phones, which serves multiple functions including photography, video recording, and now gesture recognition for projection control. By reusing the camera hardware for gesture detection, the system avoids adding dedicated sensors or complex hardware, thus minimizing the increase in device complexity while enabling simplified gesture-based operation.

AI summary
This application discloses a projection method and system, and belongs to the field of terminal technologies. The method includes: A first device displays first content, detects a first gesture operation, and recognizes the detected first gesture operation, where the first gesture operation is a continuous and moving gesture operation; a second device detects the first gesture operation, and recognizes the detected first gesture operation, where the second device establishes a communication connection to the first device; if recognizing that the first gesture operation is a projecting gesture, the first device projects, to the second device, the first content displayed by the first device; and if recognizing that the first gesture operation is a projected gesture, the second device receives the first content projected by the first device, and displays the first content on the second device. In this way, a user performs a projection gesture near the first device and the second device, to quickly trigger the first device to project screen content to the second device, thereby improving projection efficiency and flexibility, and increasing projection manners.
