Using audio signals to identify when client devices are co-located

摘要

A technique manages an online meeting. The technique includes providing an audio output signal to a first client device currently participating in the online meeting. The audio output signal directs the first client device to play a particular sound (e.g., a unique tone or a unique series of tones). The technique further involves receiving an audio input signal from a second client device. The audio input signal includes the particular sound. The technique further involves identifying the second client device as being co-located with the first client device in response to the audio input signal which includes the particular sound. Such operation enables the electronic circuitry (e.g., a processing circuit of an online meeting server) to learn whether any client devices are co-located and accordingly associate multiple devices to a single user connected to the online meeting.

主权项

1. A method of managing an online meeting, the method comprising:
providing, by electronic circuitry, an audio output signal to a first client device currently participating in the online meeting, the audio output signal directing the first client device to play a particular sound; receiving, by the electronic circuitry, an audio input signal from a second client device, the audio input signal including the particular sound; and identifying, by the electronic circuitry, the second client device as being co-located with the first client device in response to the audio input signal which includes the particular sound; wherein a first audio input signal, from a first candidate device, includes the particular sound at a first volume level; wherein a second audio input signal, from a second candidate device, includes the particular sound at a second volume level; and wherein identifying the second client device includes selecting, as the second client device, one of the first and second candidate devices based on the first and second volume levels.
