<p>Harry,</p>
<p>That's a great discovery/suggestion for the LCTG meetings.</p>
<p><u><i><b>One question (or suggestion for the Test Run)</b></i></u>:
How does the Owl behave in an un-moderated environment, where two
or more attendees attempt to speak while someone else is speaking?</p>
<ul>
<li>Does the device broadcast the superposition of all unmuted
microphones?</li>
<li>Does the "voice presence" in the main speaker's microphone
suppress the input of the other microphones?</li>
</ul>
Cheers,
<p>Tony Galaitsis</p>

<div class="gmail_default">I have been experimenting with an
interesting device, the Meeting Owl Pro, that may provide most
of the capabilities required to run Hybrid Meetings in
conjunction with a conferencing application such as Zoom.
Here is a picture of the device:</div>

<div class="gmail_default">This device connects to a laptop and
provides a replacement for the camera, microphone, and speaker
used in a Zoom conference. The components of this device are:</div>
<div class="gmail_default">
<ol>
<li><span>A </span><b>360º camera</b><span> that can pick
out from the 360º image the people in a meeting room who
are speaking based on the sounds picked up from 8
unidirectional microphones arranged around the Meeting
Owl Pro cylinder. The complete 360º video </span>image
is combined<span> with the identified speakers is one of
the outputs of the device. The 8 separate
unidirectional microphone signals are combined into one
omnidirectional audio signal which is another output of
the device.</span><br>
<br>
<div><span><img

alt="image.png" class="" width="549" height="324"></span><br>
<br>
<div><span>The acoustic energy from each of the 8
unidirectional microphones is analyzed to determine
the portions of the 360º image that ought to be
shown as active speakers. These two parts (the 360º
image and the identified speakers) are combined into
the output video stream from the device:</span></div>
<br>
<span><img src="cid:part3.6FA96C9E.63CD9145@verizon.net"
alt="image.png" class="" width="543" height="549"></span></div>
</li>
<li>The audio picked up by the <b>omnidirectional microphone</b>
is another one of the outputs of the Owl device.</li>
<li>The device also contains an array of <b>speakers </b>so
that everybody in the room can hear an audio signal
received by the device.</li>
</ol>
</div>
<div class="gmail_default">When used with an Internet
Conferencing System such as Zoom, the video and audio output
of the Owl can be shown as one participant of Zooms multiple
participants. The normal shared presentation capability can
still be used to show the content of a talk, shown on a large
screen in the meeting room or on a computer screen to a remote
participant of the conference.</div>
<div class="gmail_default"><br>
</div>
<div class="gmail_default">The following video shows the Meeting
Owl Pro being used with Zoom and connected to remote
participants over Zoom:</div>

</ul>
<div>On Friday, we will attempt to try out this experimental
setup. Although at one point I thought of having a group of
us gather at the Community Center, Jerry Slate provided some
convincing evidence why we shouldn't do this because of the
fierceness of the Delta variant of COVID-19 in an indoor
setting.</div>
<div><br>
</div>
<div>At 1:30 pm we will start the meeting using the normal
LC&T URL:</div>
<ul>
<li><a href="https://zoom.us/j/97261460830"
moz-do-not-send="true">https://zoom.us/j/97261460830</a></li>
</ul>
<div>We will record the meeting so that anyone who
can't attend can see what transpired.</div>
<div><br>
</div>
<div>My wife Marsha and I will simulate the audience in the
Meeting Room where we will use the Owl Device. Everyone
else will join as remote members of the meeting.</div>
<div><br>
</div>
<div>I think that is it for now. Please let me know if you
have any questions or I have forgotten something.</div>
<div><br>
