Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to determine the attached and detached states of devices that are designed to be worn on a predetermined portion, such as earphones, as they cannot effectively utilize acceleration data from a single device to determine the positional relationship between multiple devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If acceleration data from a single device is used, then the device complexity is reduced, but the measurement precision of device state detection deteriorates
Solution Approach 1:
The patent combines acceleration data from multiple devices (first device and second device) to determine the attached and detached state. By merging the data from both devices, the system achieves more accurate state detection than would be possible with single-device data alone, while maintaining reasonable system complexity through coordinated processing.
Solution Approach 2:
The acceleration sensors in each device serve multiple functions: they detect both the individual device's motion state and contribute to determining the relative positional relationship between devices. This multi-functionality allows the same sensor data to be used for multiple detection purposes, improving measurement precision without proportionally increasing device complexity.
2Measurement precision
If acceleration data from multiple devices is shared, then the measurement precision of device state detection is improved, but the device complexity increases
Solution Approach 1:
The determination process is segmented between multiple devices, with each device independently processing its own acceleration data and contributing to the overall state detection. This segmentation allows each device to maintain relatively simple individual processing while achieving improved measurement precision through coordinated multi-device operation.
Solution Approach 2:
The system uses feedback from acceleration data comparison between devices to continuously refine the determination of attached and detached states. By incorporating feedback from multiple data sources, the system achieves higher measurement precision while managing complexity through iterative refinement rather than complex upfront processing.
3Ease of operation
If only single device acceleration data is used, then the ease of operation is maintained, but the reliability of state detection deteriorates
Solution Approach 1:
Each device independently performs acceleration data processing and state determination using its own sensor data, maintaining ease of operation at the individual device level. The system achieves improved reliability through the coordinated self-service of multiple devices, where each device contributes to the overall detection without requiring complex external control.

AI summary
The present technology relates to an information processing system and an information processing method capable of determining what cannot be determined with single data by sharing acceleration data between a plurality of devices. Whether or not a first device and a second device that are attachably and detachably worn on a predetermined portion so as to face each other are in a relationship of facing positions is determined on the basis of a first acceleration and a second acceleration that are accelerations of the first device and the second device, respectively, and the attached and detached state of the first device and the second device is detected. Alternatively, an acceleration of a first device is transmitted to a second device connected to the first device by wireless communication, through the wireless communication.
