Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an optical pointing system is used for position designation, then the user can designate arbitrary positions on the display screen, but the input device can only perform simple position designation operations
Solution Approach 1:
The input device is enhanced with imaging means to perform multiple functions: position designation, object selection, and inclination-based operations. The device can designate positions on the display screen, select objects by pointing, and perform replacement operations by rotating, creating a multi-functional input system that resolves the limitation of single-function operation
2Ease of manufacture
If the input device structure is kept simple for position designation, then the device is easy to manufacture, but the device cannot perform complex operations like rotating and rearranging objects
Solution Approach 1:
The input device incorporates imaging means that enables it to perform multiple operations including position designation, object selection, and inclination-based manipulation. This multi-functional capability allows the device to support complex game operations like rotating and rearranging objects without requiring multiple separate devices
Solution Approach 2:
The patent replaces complex mechanical operation mechanisms with optical imaging and electronic processing. The imaging means captures marker positions and device inclination, and electronic calculations determine operation parameters, substituting mechanical complexity with optical-electronic systems that are easier to manufacture while providing richer capabilities
3Ease of operation
If the input device only designates positions on the screen, then the operation is simple, but the gameplay becomes unentertaining and limited
Solution Approach 1:
The input device performs both simple position designation and complex manipulation operations. Users can designate positions on the display screen and also perform object selection, rotation, and rearrangement by pointing and rotating the device, providing diverse gameplay operations that maintain simplicity while enhancing entertainment value
Solution Approach 2:
The patent adds a new dimension of operation by utilizing device inclination in addition to position designation. The imaging means detects the inclination of the input device, enabling operations like rotating objects on the screen by rotating the device, thereby adding spatial dimensionality to the interaction and enhancing gameplay engagement

AI summary
An information processing apparatus calculates or obtains inclination data which changes in accordance with the inclination of an input device, from the operation data obtained from the input device. The operation data includes at least one of data on a taken image taken by the imaging means, data representing predetermined two positions in the imaging target in the taken image, data representing a direction connecting the two positions, and inclination data representing an inclination of the input device which is calculated based on the direction. The information processing apparatus replaces an object (panel, etc.) displayed on a screen with another object based on the inclination data and displays the replacement result.
