Bluetooth Audio Routing Based on Device Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face issues with audio presentation during telephonic communications when Bluetooth-enabled devices automatically connect, causing audio to be directed to a device that is not conveniently accessible due to automatic connection without considering the user's proximity.
Innovation Solution
A system that determines the distance between connected Bluetooth devices and decides which device to present audio based on this distance, allowing the user to choose the appropriate device for audio output during calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If Bluetooth devices automatically connect without distance consideration, then connection establishment is simplified and faster, but audio output reliability deteriorates when the connected device is not conveniently accessible
Solution Approach 1:
The system performs preliminary distance determination between the first device and second device before establishing the telephonic communication connection. Based on the determined distance, the system pre-selects the appropriate audio output device, ensuring that audio will be reliably presented to a conveniently accessible device from the outset, thus preventing the problem of audio being directed to an inaccessible device.
2Device complexity
If audio is directed to the connected Bluetooth device regardless of distance, then device complexity is reduced, but ease of operation deteriorates when the Bluetooth device is far from the user
Solution Approach 1:
The system determines the distance between devices in advance and pre-configures the audio output routing based on this distance information. This preliminary action eliminates the need for complex real-time adjustments during the call, maintaining simple device logic while ensuring audio is directed to the most accessible device, thereby improving ease of operation.
3Ease of manufacture
If the system always uses the connected Bluetooth device for audio output, then manufacturing precision requirements are minimized, but adaptability deteriorates when user proximity to devices changes
Solution Approach 1:
The system performs preliminary distance determination and uses this information to adaptively select the appropriate audio output device before the telephonic communication begins. This approach maintains simple manufacturing requirements while achieving high adaptability by making the audio routing decision based on actual user proximity to devices, allowing the system to adapt to different usage scenarios.

AI summary
In one aspect, a first device includes a processor, a Bluetooth transceiver accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to, based on at least one signal received at the Bluetooth transceiver, determine a distance from the first device to a second device different from the first device. The instructions are also executable to, based on the distance, execute at least one function at the first device associated with a telephonic communication.
