Portable Device Candidate Selection via Sound Source Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices face challenges in selecting the correct candidate device to connect to, especially when multiple devices are present in the same location, leading to potential connections with incorrect devices.
Innovation Solution
The solution involves determining the locations of candidate devices and identifying those that satisfy specific location criteria. Using the microphones of a portable device, the location of a sound source is determined and compared to the locations of the candidate devices. Based on this comparison, a candidate device is selected for connection, with additional sensor information used if the sound source location does not provide a sufficient match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable device selects candidate devices based on location alone, then the connection process is simple and fast, but the accuracy of selecting the correct device is reduced when multiple devices are present
Solution Approach 1:
The device selection process is segmented into multiple independent criteria: location-based selection, sound source-based selection, and sensor-based selection. Each criterion operates independently and can be applied in sequence, allowing the system to break down the complex selection task into manageable segments that improve accuracy without overwhelming complexity
Solution Approach 2:
Sound source detection acts as an intermediary criterion between location-based selection and final device connection. The system first identifies candidate devices by location, then uses sound source detection as a mediator to further narrow down and verify the correct device, improving selection accuracy without requiring direct complex device-to-device communication
2Reliability
If additional sensors are used to verify device selection, then the accuracy of connection is improved, but the time and energy required for selection increases
Solution Approach 1:
The system applies partial action by using additional sensors only when necessary - specifically when location-based selection identifies multiple candidate devices or when sound source detection is insufficient. This selective application of additional sensing avoids the time penalty of always using all sensors while maintaining high accuracy when needed
Solution Approach 2:
Location-based selection is performed as a preliminary action to quickly identify candidate devices before engaging more time-consuming sensor-based verification. This preliminary filtering reduces the number of devices that require extensive sensor analysis, thereby minimizing overall selection time while maintaining accuracy

AI summary
Examples of the disclosure relate to selecting candidate devices for connecting with one or more portable devices. In examples of the disclosure two or more candidate devices that satisfy location criteria are identified. Microphones of a portable device are used to determine a location of a sound source relative to the at least one portable device and the location of the sound source is compared with respective locations for the two or more candidate devices. A candidate device for connecting to the at least one portable device is selected based, at least in part, on the comparison between the location of the sound source and a location for the selected candidate device.
