Exclusion Zones

Now, there's one other thing we should all definitely be aware of with Seervision

which is that it's seeing people in two dimensions,

which means if it sees a picture of somebody or a video of somebody on a screen,

it is going to see that in the same way it would see a real person.

Let's see a quick example now on the screens right now

I just have a couple of Q-SYS logos and I've actually added a big zone here on the side,

which I want to use for when people enter this area from the site.

Now, if I switched my video content here to something else,

we're going to see that it can identify some people on screen.

Not really sure who these two guys are,

and it's starting to track the people on screen as if they were real presenters.

This is problematic.

We can avoid this by adding exclusion zones which act as a kind of anti trigger zone.

When you draw an exclusion zone over a trigger zone,

it will make the trigger zone ignore people who are completely inside the exclusion zone.

I'm drawing a couple of exclusion zones here,

one for each display and after we've adjusted them

and given them a little bit of margin so they completely cover the display.

You can see that people on screen are shown with a red bounding box,

meaning they are not eligible to be tracked.

I can turn the big trigger zone back on and nothing happens

until the real presenter walks into that zone.

Now, the reason I'm still being tracked,

even though I'm walking into the exclusion zone,

is that I'm only partly inside the exclusion zone so it doesn't have an effect.

Looks good.

People on screen are ignored and real people are just tracked normally.
