Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired mouse is used, then the mouse operation is stable and continuous, but the movement is restricted due to cable length and material
Solution Approach 1:
The patent replaces the mechanical mouse system with an optical recognition system. A camera captures images of the user's palm, and image processing algorithms detect palm movement to simulate mouse operations. This substitution eliminates the physical cable constraint while maintaining operational stability through continuous image capture and processing.
Solution Approach 2:
The patent creates a virtual copy of mouse functionality through software-based palm movement recognition. Instead of using physical mouse hardware, the system captures visual information of the palm and processes it to generate equivalent mouse operations, thereby expanding movement freedom without sacrificing operational reliability.
2Length of moving object
If a wireless mouse is used, then the movement freedom is improved, but frequent battery replacement is needed due to higher electricity consumption
Solution Approach 1:
The patent replaces the battery-powered wireless mouse with a camera-based optical recognition system. The system uses existing computer hardware (camera, processor) to capture and process palm movement images, eliminating the need for dedicated battery consumption while maintaining movement freedom.
Solution Approach 2:
The patent utilizes existing computer hardware components (camera, processor, display) for multiple purposes. The camera serves both as a input device for palm recognition and as part of the existing computer system, thereby avoiding additional energy consumption requirements while providing wireless-like movement freedom.
3Measurement precision
If traditional mouse hardware is used, then the cursor control is precise, but the operational sensitivity is limited by physical constraints
Solution Approach 1:
The patent implements a dynamic system where the camera continuously captures palm movement in real-time, and the processing system dynamically adjusts to different palm movement patterns. This allows the system to maintain cursor control precision while adapting to various user operations, thereby improving operational sensitivity compared to static mechanical mice.
Solution Approach 2:
The patent creates a virtual representation of mouse operations through palm image processing. By capturing and processing palm movement visually, the system achieves both precise cursor control and enhanced operational sensitivity, as the optical system can detect subtle palm movements that would be difficult with mechanical mice.

AI summary
A system and method for simulating a computer mouse uses a camera to capture images of a user's palm on a plane, transfers the images to a computer, analyzes the images to determine movement information of the user's palm, and determines a corresponding mouse operation according to preset associations between movements of the user's palm and operations on mouse buttons. The system and method further execute a computer command corresponding to the mouse operation associated with the movement information of the user's palm, so as to activate a action of a cursor displayed on a display screen of the computer.
