Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bulky gamepad controllers and touch pads are used for user operation, then the system can provide control functionality, but the device complexity and ease of operation deteriorate due to the need for additional hardware and less natural interaction
Solution Approach 1:
The patent extracts the hand detection functionality from traditional controllers and implements it directly within the VR HMD system using onboard image sensors. This eliminates the need for separate bulky controllers while maintaining control capabilities through hand gesture recognition in the virtual environment.
Solution Approach 2:
The patent replaces mechanical control interfaces (gamepad, touch pad) with an optical/electromagnetic system using image sensors to capture hand movements. The system processes visual data to detect hand presence and gestures, substituting physical mechanical inputs with visual recognition and digital signal processing.
2Ease of operation
If hand presence and gestures are detected using image sensors, then the ease of operation improves through more natural interaction, but the measurement precision and reliability may worsen due to challenges in accurately detecting hand movements in 3D space
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors hand position and gestures through image sensors, processes this visual information to identify control intentions, and provides real-time feedback to the virtual environment. This iterative feedback loop enhances detection accuracy by adapting to user actions and environmental conditions.
Solution Approach 2:
The patent transitions from 2D image sensor data to 3D spatial understanding by processing hand gesture information across multiple dimensions. The system maps hand movements in the physical world to corresponding virtual space coordinates, enabling precise gesture recognition and control in the virtual environment through dimensional transformation.
