Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sets of cameras are used to capture 3D motion with depth information, then the ability to interpret motion commands is improved, but the device complexity and synchronization difficulty increase
Solution Approach 1:
The patent combines multiple cameras into a single integrated multi-view video recording device that captures images from multiple viewpoints simultaneously. This merging approach maintains the ability to extract 3D motion information while simplifying the system architecture and eliminating the complexity of coordinating multiple independent camera systems.
Solution Approach 2:
The multi-view video recording device serves multiple functions: it captures 2D images from different viewpoints, extracts depth information, tracks finger motion, and provides data for command recognition. This multi-functionality reduces the need for separate specialized devices and simplifies the overall system.
2Adaptability or versatility
If multiple cameras are used to capture finger motion, then 3D space operation capability is improved, but synchronization precision requirements increase
Solution Approach 1:
By integrating multiple camera views into a single coordinated recording device, the system achieves synchronized capture of 3D finger motion without requiring complex synchronization between multiple independent devices. The unified device architecture ensures consistent timing and coordinate systems across all camera views.
3Measurement precision
If depth computation is performed on captured images, then motion command interpretation is improved, but the system becomes more sensitive to parameter definition problems
Solution Approach 1:
The system incorporates feedback mechanisms where the multi-view video recording device continuously captures and processes finger motion data, allowing for real-time adjustment and verification of depth computation parameters. This feedback loop enables the system to compensate for parameter definition issues and maintain stable interpretation results.

AI summary
A three-dimensional (3D) human-computer interaction system that supports mouse operations through the motion of a finger and an operation method thereof are provided. In the provided system and method, a multi-view video recording device captures an image of a finger of an operator, and has an information connection with an electronic information device through an interaction handling program. After the interaction handling program is executed, a CPU of the electronic information device performs operations such as computation, synthesis, image presentation, gesture tracking, and command recognition on the captured image to interpret a motion of the finger of the user. Accordingly, the user may perform operations on an operation interface of the electronic information device by using the finger in a 3D space in a noncontact mode. The present invention is particularly applicable to application software with 3D space operations as it can perform 3D interaction with the application software.
