Now, there's one other thing we should all definitely be aware of with Seervision
00:10
which is that it's seeing people in two dimensions,
00:13
which means if it sees a picture of somebody or a video of somebody on a screen,
00:18
it is going to see that in the same way it would see a real person.
00:21
Let's see a quick example now on the screens right now
00:25
I just have a couple of Q-SYS logos and I've actually added a big zone here on the side,
00:32
which I want to use for when people enter this area from the site.
00:37
Now, if I switched my video content here to something else,
00:41
we're going to see that it can identify some people on screen.
00:45
Not really sure who these two guys are,
00:47
and it's starting to track the people on screen as if they were real presenters.
00:53
This is problematic.
00:54
We can avoid this by adding exclusion zones which act as a kind of anti trigger zone.
01:00
When you draw an exclusion zone over a trigger zone,
01:03
it will make the trigger zone ignore people who are completely inside the exclusion zone.
01:09
I'm drawing a couple of exclusion zones here,
01:12
one for each display and after we've adjusted them
01:15
and given them a little bit of margin so they completely cover the display.
01:18
You can see that people on screen are shown with a red bounding box,
01:22
meaning they are not eligible to be tracked.
01:26
I can turn the big trigger zone back on and nothing happens
01:29
until the real presenter walks into that zone.
01:33
Now, the reason I'm still being tracked,
01:35
even though I'm walking into the exclusion zone,
01:37
is that I'm only partly inside the exclusion zone so it doesn't have an effect.
01:42
Looks good.
01:43
People on screen are ignored and real people are just tracked normally.
