Cours 1 sur 5 dans Specialization Virtual Reality

This course will introduce you to Virtual Reality (VR). The course will teach you everything from the basics of VR- the hardware and the history of VR- to different applications of VR, the psychology of Virtual Reality, and the challenges of the medium. The course is designed for people who are new to VR as a medium. You may have experienced some virtual reality before, and may have some hardware- but this course is suitable to individuals who have never experienced VR and those who do not have much hardware- we will explain Mobile VR as well as devices such as the Oculus Rift and HTC Vive. Introduction to Virtual Reality is the first course in the Virtual Reality Specialisation. A learner with no previous experience in Virtual Reality and/or game programming will be able to evaluate existing VR applications, and design, test, and implement their own VR experiences/games using Unity by the end of the specialisation.

À partir de la leçon

Virtual Reality- Hardware and History

In this week, we’ll cover the basics of VR. We’ll start by sharing a definition of Virtual Reality, and exploring VR hardware, and then you’ll see demonstrations of a range of VR Head Mounted Devices. In the latter part of the week, you will hear more about the history of Virtual Reality and finish the week by drafting your ideas for a VR application.

Hi, I'm Dave and this is Isabel.

And we are going to tell you all about this stuff that you

need to use the PlayStation VR headset.

So first thing you need, obviously, is the headset.

So, the PlayStation VR headset, feeling it,

it's actually the heaviest one out of all the ones you can buy,

but it's actually most comfortable.

So as you can see here, it's got all the padding in here like the cushioning,

but it also is really good at adjusting to fit different people's heads.

So, there's a button on the back right here, when you press it in,

you pull it forward like that, and then,

it's adjustable, and they're big enough to fit over Dave's head.

Thanks.

You'll also see that there are these blue lights right at the back here.

When it's on, the blue lights appear on the front of it,

and these lights actually used sort of trackers, right?

To be picked up by this stereo cameras.

Well, do you want to talk a little bit about the weight distribution?

Yeah. Well, the interesting thing is,

I think because Sony had been so experienced at making

things like headphones and other electronics,

they've done a great job of the weight distribution too, as Isabel said.

Although it's the heaviest, they actually,

it feels like the lightest.

And the other thing to say is these trackers,

when they get tracked by this camera,

that gives us full positional tracking.

So not only do we know which way it's rotated,

we also know where you are in space,

which is different to their current mobile setups

where they just know the rotation of the headset.

So the main thing you need to power the PlayStation VR headset is the PlayStation 4.

It also comes with this box as well,

which is the power but it also splits up the signal between the headset,

and the PlayStation, and the TV.

One last thing about it is that you can plug in your own headphones on the side here,

there's a lot of control panel with the volume controls,

and also it's way you turn on/off the headset.

And as well as Isabel said,

you can plug in your own headphones on this box.

Not only does it do the visual video splitting,

but it also does all the calculation for the sound,

so it can place it all around you in 3D.

You can do some experiences just with the headset,

but also, you can use controllers.

So this is a traditional game controller.

It's the standard PlayStation DualShock 4.

This has gyros in it and that means again,

you know the orientation of it,

but you don't know exactly where it is in space.

It does have this light bar,

and that can be tracked by this camera.

But as soon as,

so you can imagine it like that, as soon as you go out like that, you lose that tracking.

So it's that limited what that can do.

It has a bunch of buttons on it,

these classic PlayStation buttons,

and this D-pad, and then,

these two joysticks, and even has these shoulders as well.

So this is great for playing all kinds of games,

but it can be a bit limited in VR because you really want to have hands.

And that's where these guys come in.

So these are PlayStation Move controllers.

They were actually released about 10 years ago,

way before any VR was happening.

And as motion controllers,

similar to the Nintendo Wii controllers,

and when these are on,

these ping pong balls glow different colors,

and again, the camera can track them.

So altogether, the camera and the processing of that feed

has got a lot of work to do because it's going to track these lights on from the headset,

and track these as well.

These have the same gyros in this,

so we have some orientation.

And then, with these glowing ping pong balls,

we actually get very precise information the way your hands are.

Using these triggers that are on them,

we can then replicate what it's like to pick things up, and at that point,

you get some really great VR experiences because not only are you in full VR,

you've got great 3D sound, but then,

you've got hands as well,

and that feels very very natural, and very intuitive.

And so, I think that's one of the big benefits of the high-end systems now.

They've got these hand controllers if you like,

but you can tell from these,

they've got these tiny buttons on the front which is

unlike any of the other hand controllers for VR.

And that's because they were originally

designed where they thought you'd be able to see them,

but now you can't because you're in VR.

So, I wouldn't be surprised if they

redesign them at some point to make that a bit clearer.
