Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple infrared sensors are used to detect movement in five directions at five positions, then measurement precision is improved, but device complexity increases and cost increases
Solution Approach 1:
The patent extracts the movement detection function from multiple infrared sensors and concentrates it into a single controller with acceleration and inclination sensors. This extraction reduces system complexity while maintaining the ability to detect movement in multiple directions through sensor fusion algorithms that process data from the consolidated sensors.
Solution Approach 2:
The controller is designed as a multi-functional device that performs both inclination detection and acceleration detection, replacing the need for separate infrared sensors at multiple positions. This universal device can detect movement in all five directions through integrated sensor data processing, reducing overall system complexity.
2Ease of operation
If a controller with physical quantity sensor is used for dancing simulation, then ease of operation is improved, but measurement precision deteriorates due to difficulty in accurately detecting intricate movements
Solution Approach 1:
The system provides real-time feedback by displaying instruction images that show the correct controller movements and comparing them with actual sensor data. This feedback mechanism helps users adjust their movements to achieve more accurate detection results while maintaining ease of operation through visual guidance.
Solution Approach 2:
The patent changes the detection parameters by using both acceleration and inclination sensors simultaneously, and by processing their combined data through algorithms that account for the controller's orientation and movement dynamics. This parameter transformation enables accurate detection of intricate dance movements while keeping the operation simple for users.

AI summary
An input instruction device for a simulation system performs a process that generates and displays an instruction image that instructs a given movement of a controller including an acceleration sensor, and a process that acquires a signal from the acceleration sensor included in the controller to detect the movement of the controller, and determines the degree of conformity of the detected movement of the controller with the instructed movement instructed by the instruction image.
