There's a couple of key factors that I 
want you to bear in mind with AR spatial UI design.

00:00:14.340 --> 00:00:19.055
One of them is related to *exploration with head rotation*.

00:00:19.055 --> 00:00:22.190
So, how much head rotation should you offer?

00:00:22.190 --> 00:00:28.045
And – you know – it might help with you just 
rotating your own head and imagining a hologram here or there,

00:00:28.045 --> 00:00:32.000
and actually doing that and see 
how much you can get away with.

00:00:32.000 --> 00:00:37.609
Have a few other people do it as well. So, head rotation I think maybe in adults is going to be

00:00:37.609 --> 00:00:42.880
probably harder to do, but this relates to *Field Of View or FOV*,

00:00:42.901 --> 00:00:48.281
something in AR and VR that from a UX perspective

00:00:48.281 --> 00:00:52.691
we need to know about. It's where you *ideally place the content*.

00:00:52.691 --> 00:00:58.250
Now, the amateur mistake is to place content everywhere and get the head rotating, involved and

00:00:58.250 --> 00:01:05.865
down here and up here, to the point where someone's dizzy or nauseous or about to fall over from excitement, maybe.

00:01:06.060 --> 00:01:11.207
What studies have shown is that our ideal 
content area is in that

00:01:11.207 --> 00:01:14.414
40° range of field of view.

00:01:14.414 --> 00:01:19.896
And it means that you don't have to 
worry as much about a 360 experience

00:01:19.896 --> 00:01:25.099
unless you're deliberately trying to hide something or place something in a place

00:01:25.099 --> 00:01:29.726
where that creates excitement and mystery or suspense or curiosity.

00:01:29.726 --> 00:01:34.963
But generally when someone's interacting with an AR hologram or a visualization,

00:01:34.963 --> 00:01:40.737
they're doing it in this range in front of them, almost the way you would closely talk to a colleague

00:01:40.737 --> 00:01:44.429
if you were at a conference and you'd be in the space in front.

00:01:44.880 --> 00:01:50.292
And the head rotation actually is recommended, a 30-degrees field of view

00:01:50.292 --> 00:01:55.650
in terms of the motion, which is about 
a comfortable range right here

00:01:55.650 --> 00:02:02.820
of looking; and so, it's not this or this or this or this; it's a lot more comfortable  

00:02:02.820 --> 00:02:06.846
than that, and I think knowing that that's 
where your focal point and

00:02:06.846 --> 00:02:10.533
then you can start to narrow what you can do with your hologram

00:02:10.533 --> 00:02:13.524
and the space you have as well.
