Multi-stage Body Engagement Detection for Wireless Audio Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless audio devices experience delays in pairing with audio sources, leading to inconvenient user experiences due to the need for users to wait for the pairing process to complete before they can use the device, especially when the device is not fully engaged with the user's body.
Innovation Solution
The audio device includes sensors to detect user presence and orientation, initiating the pairing process before the device is fully engaged, allowing it to transition to an active mode and establish a wireless communication bond more quickly, thereby reducing the delay between donning the device and being able to use it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pairing process is initiated only after the device is fully engaged with the user's body, then the reliability of pairing is improved, but the pairing time and user waiting time increase
Solution Approach 1:
The system initiates the pairing process in advance based on preliminary detection of user presence through sensors (proximity sensors, motion sensors, orientation sensors) before the device is fully engaged with the user's body. This preliminary action allows the pairing to occur during the engagement process rather than waiting for completion, thereby reducing pairing time while maintaining reliability through multi-stage verification.
2Productivity
If the device transitions to active mode immediately upon detecting user presence, then the productivity and responsiveness are improved, but the power consumption increases
Solution Approach 1:
The device implements dynamic mode transitions based on multi-stage engagement detection. The system remains in low-power mode initially, then transitions to active mode only after confirming full engagement through multiple sensor inputs (proximity, motion, orientation). This dynamic approach optimizes power consumption by avoiding premature activation while ensuring quick responsiveness once engagement is confirmed.
Solution Approach 2:
The system uses continuous feedback from multiple sensors (proximity sensors, motion sensors, orientation sensors) to monitor engagement status and dynamically adjust power mode. The feedback mechanism allows the device to make informed decisions about when to transition from low-power to active mode, balancing responsiveness with power efficiency based on real-time engagement conditions.

AI summary
According to an aspect of the disclosure, an audio device is provided comprising a communications interface configured to be communicatively coupled to an audio source, at least one sensor, and a controller configured to control the audio device to be in a low-power mode, receive, from the sensor(s), information indicative of a presence of a user's body, initiate, via the communications interface responsive to receiving the information, a wireless communication pairing process to establish a wireless communication bond with the audio source prior to determining that the audio device is fully engaged with the user's body, determine, subsequent to initiating the wireless communication pairing process and based on information received from the sensor(s), that the audio device is fully engaged with the user's body, and control, responsive to determining that the audio device is fully engaged with the user's body, the audio device to be in an active mode.
