Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional input device uses a single operation handler, then the device structure remains simple, but the input diversity and interaction precision are limited
Solution Approach 1:
The single operation handler is designed to detect multiple types of user inputs (shear direction, moment direction, input amount) and execute different controls based on these variations. This allows one device component to perform multiple input functions, achieving input diversity without adding multiple separate operation handlers
Solution Approach 2:
The system diversifies inputs by detecting different parameters (shear vs. moment direction, different input amounts) from the same operation handler. By interpreting variations in these parameters, the system generates multiple types of control signals, effectively increasing input diversity through parameter differentiation rather than hardware multiplication
2Measurement precision
If a conventional input device uses a single operation handler, then the device remains easy to operate, but the control precision and application process complexity are insufficient
Solution Approach 1:
The detection capabilities are segmented into distinct functional components: shear detection for movement/orientation control and moment detection for action selection. This segmentation allows each sensor type to specialize in specific detection tasks, improving measurement precision while keeping the overall device structure manageable through modular sensor integration
3Adaptability or versatility
If the system executes both first control and second control based on shear and moment inputs, then the interaction sophistication increases, but the device complexity increases
Solution Approach 1:
The controller dynamically switches between different control modes based on the detected input type. When shear input is detected, first control (movement/orientation) is executed; when moment input is detected, second control (action selection) is executed. This dynamic switching allows the system to provide sophisticated interactions without requiring all control functions to operate simultaneously, managing processing complexity through conditional execution

AI summary
An example of an information processing system determines a shear parameter including shear direction components in at least two directions and a moment parameter including moment direction components with respect to at least two axes, the shear parameter and the moment parameter relating to a user operation on an operation handler. Then, the example of the information processing system, based on a first input that is one of the shear parameter and the moment parameter, executes first control, and based on a second input that is the other of the shear parameter and the moment parameter, executes second control.
