Positional tracking Oculus Rift + Razer Hydra
Hi how are you?
Today we're going to talk about something really interesting and we're going to see it in action with the Oculus Rift
We're going to talk about positional tracking
If you remember the questions and answers video, I told you the Oculus Rift is aware of where it's looking
but it isn't aware of its spatial position
This is important in a simulation environment. Inside a cockpit we must be able to move our head closer to check the panel
Move from side to side, not just turning our head, but also moving it slightly from side to side
And using a flight simulator, well not exactly a simulator, but a small helicoters demo that will be useful to showcase it
We're going to check the difference between having positional tracking and not having it
No positional tracking
Here I am, with my Oculus Rift, ready to take off
On Oculus Rift YouTube videos, people usually shows
the two views of the Oculus Rift screen, just like you can see on screen right now
Well, I'm going to remove one of the viewports
And I'll widen the other so what you see is more similar to what I'm seeing on the Oculus Rift
And I think it will be more useful to you
You're still going to see it with a fisheye distortion
But as I told you, the Oculus Rift
needs a distortion on the image
that is fixed via software
But I think you can get an idea of what I'm seeing
But you can't feel what I'm feeling
What you see as a small screen
For me is a full helicopter cockpit
I am inside the helicopter
As I told you, this is something that you can't believe unless you try it
Anyway, let's get moving
Positional tracking
Right now, I can turn my head everywhere
And the Oculus tracks my movement perfectly
I can look back, I can see a man there
But what happens without positional tracking?
If I want to take a closer look to the panel
It doesn't matter how close I can get
The image doesn't reflect it
If I want to lean out of the window
Even if I do this
My character doesn't lean out
But it's still an awesome experience
Let's take off
I can see the island in real life size
On my right I can see a ship
Oh my God, in this moment
Just two words come to my mind
Battlefield 4
Please, EA guys
I hope you're already testing the Oculus Rift
And you can give us
something similar to this
Because this, although it's just a simple Unity demo
It's incredible! The feeling of being close to the ship
it blows my mind
Even without positional tracking it's awesome
I would love to lean out of the window
but it's not possible
Whatever I do it doesn't matter, I'm always inside
Ok
Let's land
And let's turn positional tracking on
It's very useful to look around, landing on the platform is much easier
Just a little bit more and I'm going down
Perfect!
Let's turn on positional tracking so you can see the huge difference
Meet the Razer Hydra
Ok, you're aware of the small issues caused by the lack of positional tracking in a virtual reality flight simulator
Now we're going to use the Razer Hydra
together with the Oculus Rift
to get our accurate position inside the cockpit
The Hydra, as you can see
is perfectly aware of its position
Height, controller separation, everything from the ball
that knows, thanks to a magnetical system, where are exactly both controllers
Let's go
With positional tracking
And now, to show you the positional tracking,
I'm going to use the left Razer Hydra controller
This controller will register my position inside the cockpit
The only way to get it done
is to do a little trick
I'm hanging the controller like a cowbell
So when I move inside the cockpit
The Razer will come with me
and will transmit my position to the game
So let's put on the Oculus and take off
Here I am again
With the Razer Hydra controller on my neck
And this time look at the difference
When I get close to the panel
I can see it perfectly
I can lean out of the helicopter
I can look back
There's a small glitch
Ok, the Hydra will transmit my exact position inside the cockpit,
I can even, I've got a chair here
I can sit into the copilot seat if I want
Careful
I switch chairs
And here I am
into the copilot seat
I can see my headless body
I can also lean here outside
I can go up, I can go down, I can get closer to the panel
So this is great
I will pilot again
And I can do basically the same than before
But with a much higher immersion feeling
I can get close to the ship
Take a look at this
I'm staying here stationary
I can almost
jump inside the ship
Look how I can see
Every detail of the helicopter from the outside
This is critical in flight simulators in my opinion
To be able to move your head and your body inside the cockpit
To get access to
To get access to every button, every *** out of our reach
This experience is unbelievable because it can even
track this simple head movement
So it can fool my mind even more to make me believe
I am inside the game
Who put those ballons here?
Anyway I can get close to the crate
The balloons are here!
They are here, I can touch them!
This is amazing
You don't know what it is unless you try an Oculus Rift
It does not matter how much I can try to explain the feeling of being inside
Of being able to... oh my God
I've been using it for three weeks and it still amazes me
So you can see that it tracks my movements perfectly
Both my head and my body
And this is what we hope will be
on the future commercial version of the Oculus Rift
That the OculusVR guys will implement it
We can do a flyby through the ship
With half my body outside the helicopter
So it is
Let's land
We've flown enough today
I look back
I can lean out
Done. Perfect
So
I never get tired of the Oculus
Well, that was all for today
I hope you enjoyed the video
Next time I will show you a bit of Half Life 2
See you soon!
