Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-dimensional input device is used to operate a three-dimensional environment, then the operation can be performed with existing devices, but it becomes difficult to intuitively understand and interact with the virtual three-dimensional space
Solution Approach 1:
The patent transitions from two-dimensional input devices to three-dimensional input methods by capturing the user's actual three-dimensional movements and gestures. The system acquires three-dimensional position information of the user's body parts and maps these movements directly to operations in the virtual three-dimensional space, enabling intuitive interaction that matches the spatial dimensionality of the environment being operated.
2Ease of operation
If a depth camera is used to detect positional changes for triggering input commands, then three-dimensional interaction can be achieved, but additional equipment is required which complicates the system
Solution Approach 1:
The patent utilizes the imaging unit already present in the information processing device for both display and three-dimensional input detection purposes. By processing the captured images to extract three-dimensional position information of the user's body parts, the system achieves multi-functionality where a single device component serves both visualization and interaction detection roles, reducing the need for additional specialized equipment.
3Device complexity
If only movement operation is provided for virtual objects, then the operation method is simple, but comprehensive interaction with the virtual three-dimensional space is limited
Solution Approach 1:
The patent dynamically determines the type of operation to be performed based on the user's gestures and the context within the virtual three-dimensional space. The system can perform various operations including movement, selection, manipulation, and other interactions by analyzing the user's three-dimensional movements and the spatial relationships between virtual objects, providing comprehensive interaction capabilities while maintaining intuitive and adaptable operation methods.
