Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user is guided to perform rotational operation for sensor calibration without visual guidance, then the calibration process can be completed, but the user may not understand the correct rotation method and the sensor position may change during rotation
Solution Approach 1:
The patent creates a virtual copy of the communication device in the guide image, allowing users to visually reference the correct device orientation and rotation path without physically manipulating the actual device in complex ways. The virtual representation simplifies the calibration process while maintaining position stability.
Solution Approach 2:
The patent transitions from physical three-dimensional rotation guidance to a two-dimensional graphical representation on the display device. The guide image projects the rotation path and sensor position requirements onto a visual plane, making it easier for users to understand and execute the calibration operation while maintaining spatial awareness.
2Measurement precision
If the communication device is rotated to maintain sensor position within actual space, then calibration accuracy is improved, but the operation becomes more complex and harder to understand
Solution Approach 1:
The guide image acts as an intermediary between the user and the calibration process. It visually mediates the complex rotation requirements by showing the correct device orientation and rotation path, translating physical calibration requirements into intuitive visual instructions that simplify user operation while maintaining accuracy.
Solution Approach 2:
The patent uses visual differentiation in the guide image to indicate correct versus incorrect device orientations. By changing the visual appearance (such as highlighting or coloring) based on the device's rotational state, the system provides immediate feedback that simplifies the operation while ensuring calibration accuracy.

AI summary
Provided is an information processing system which includes: a communication device including a sensor that measures information regarding a posture thereof; and an information processing device. The information processing device displays a guide image for causing a user to perform a rotational operation for rotating the communication device, and executes calibration of the sensor by using the measurement result of the sensor acquired from the communication device while the guide image is displayed. The guide image includes an image representing a reference axis to be a rotation center for the rotational operation and an image representing the communication device, and the image representing the communication device is located within the guide image so that a portion of the communication device corresponding to a position of the sensor overlaps with the reference axis.
