Hearing Device Sensor Data Correlation and Output Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing devices and communication systems face challenges in accurately and reliably combining sensor data from both the device worn on the ear and remote devices, leading to inconsistencies in data quality and reliability, particularly in terms of physical properties detected on the user or in their environment.
Innovation Solution
A hearing device and communication system that determines the correlation between sensor data from the device worn on the ear and remote data, using a processing unit to select operations for output data generation based on whether the correlation is above or below a threshold, thereby ensuring accurate and reliable data integration or reducing power consumption when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sensor data from both the hearing device and remote device are combined, then the quantity and completeness of data is improved, but the accuracy and reliability may deteriorate due to inconsistencies in data quality
Solution Approach 1:
The system dynamically changes the parameter of data source selection based on the calculated correlation degree. When correlation between hearing device sensor data and remote device sensor data exceeds a threshold, the system switches to using remote device data; otherwise, it uses hearing device data. This parameter change resolves the contradiction by adapting data source selection to real-time correlation conditions.
Solution Approach 2:
The system implements a feedback mechanism by continuously calculating the correlation degree between sensor data from the hearing device and remote device, then using this correlation information to control the data selection process. The correlation calculation provides feedback that determines whether to prioritize hearing device data or remote device data, ensuring reliable output data selection.
2Quantity of substance
If remote data is always incorporated into output data, then data completeness is improved, but power consumption increases due to continuous data processing and transmission
Solution Approach 1:
Instead of always incorporating remote data, the system applies partial action by selectively using remote device data only when the correlation degree exceeds a threshold. This partial incorporation of remote data maintains output data completeness when beneficial while avoiding unnecessary power consumption when remote data correlation is low.
3Measurement precision
If correlation calculation and selective data processing are implemented, then output data quality is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system extracts only the essential correlation information needed for data selection, rather than processing all possible data aspects. By calculating correlation degree as a single metric and using it to control data source selection, the system maintains high output data quality while avoiding excessive processing complexity.
