Embodiments of systems and methods for using contextual center-of-gravity for outputting audio in collaborative environments are described. In some embodiments, an Information Handling System (IHS) may include: a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: identify a first position of a first participant and a second position of a second participant during a collaboration session; calculate a Center-of-Gravity (CoG) based, at least in part, upon the first and second positions; and output audio during the collaboration session with a level determined based upon the CoG.
1. An Information Handling System (IHS), comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to:
identify a first position of a first participant and a second position of a second participant during a collaboration session;
calculate an average distance from each participant's position to a reference location in three-dimensions using a first height of the first participant and a second height of the second participant;
calculate a Center-of-Gravity (CoG) based, at least in part, upon the average distance; and
output audio during the collaboration session with a level determined based upon the CoG.
2. The IHS of claim 1 , wherein to identify the position, the program instructions, upon execution by the processor, further cause the IHS to use at least one of: a proximity sensor, an RGB camera, or an IR/NIR camera.
3. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to classify the first and second participants as at least one of:
near-field, mid-field, or far-field.
4. The IHS of claim 1 , wherein to output the audio, the program instructions, upon execution by the processor, further cause the IHS to increase the level during at least a portion of the collaboration session in response to movement of the CoG away from the reference location.
5. The IHS of claim 4 , wherein to output the audio, the program instructions, upon execution by the processor, further cause the IHS to decrease the level during at least a portion of the collaboration session in response to movement of the CoG toward the reference location.
6. The IHS of claim 4 , wherein to output the audio, the program instructions, upon execution by the processor, further cause the IHS to look-up a loudness value corresponding to the level.
7. The IHS of claim 1 , wherein the IHS is coupled to an electronic display where a remote video feed is rendered during at least a portion of the collaboration session, and wherein the reference location comprises the electronic display.
8. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to identify a first context of the first participant and a second context of the second participant, and to calculate the average distance using weights associated with the first and second contexts, respectively.
9. The IHS of claim 8 , wherein the program instructions, upon execution by the processor, further cause the IHS to classify each of the first and second context as at least one of:
speaking, gesturing, or whiteboarding.
10. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to:
receive a plurality of audio streams from a remote location;
determine that an audio stream contains speech by a third participant; and
in response to a position of the third participant in the remote location, adjust the level.
11. The IHS of claim 1 , wherein the program instructions, upon execution by the processor, further cause the IHS to:
receive a plurality of audio streams from a remote location;
determine that an audio stream contains speech by a third participant; and
in response to a context of the third participant in the remote location, adjust the level.
12. A method, comprising:
identifying a first position of a first participant and a second position of a second participant during a collaboration session;
calculating an average distance from each participant's position to a reference location in three-dimensions using a first height of the first participant and a second height of the second participant;
calculating a Center-of-Gravity (CoG) based, at least in part, upon the average distance; and
outputting audio during the collaboration session with a sound volume determined based upon the CoG.
13. The method of claim 12 , further comprising calculating an increase or decrease in the sound volume during at least a portion of the collaboration session in response to movement of the CoG.
14. The method of claim 12 , wherein outputting the audio further comprises using a loudness table with acoustic calibration data.
15. The method of claim 12 , further comprising identifying a first context of the first participant and a second context of the second participant, and calculating the average distance using weights associated with the first and second contexts, respectively.
16. A hardware memory device having program instructions stored thereon that, upon execution by a processor of an Information Handling System (IHS), cause the IHS to:
identify a first position of a first participant and a second position of a second participant during a collaboration session;
calculate an average distance from each participant's position to a reference location in three-dimensions using a first height of the first participant and a second height of the second participant;
calculate a Center-of-Gravity (CoG) based, at least in part, upon the average distance; and
output audio during the collaboration session with a level determined based upon the CoG.
17. The hardware memory device of claim 16 , wherein the program instructions, upon execution by the processor, further cause the IHS to:
receive a plurality of audio streams from a remote location;
determine that an audio stream contains speech by a third participant; and
in response to a position of the third participant, adjust a level of the audio stream relative to other audio streams.
18. The hardware memory device of claim 16 , wherein the program instructions, upon execution by the processor, further cause the IHS to:
receive a plurality of audio streams from a remote location;
determine that an audio stream contains speech by a third participant; and
in response to a context of the third participant, adjust a level of the audio stream relative to other audio streams.
