Cours 1 de 5 dans Réalité virtuelle Spécialisation

Visualiser le programme de cours

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.

This course was very informative. I also found it challenging, which is a good thing. I was introduced to aspects of VR that had not considered, such as the psychological aspects.

Being a non-techie, I find this course quite easy to understand. The required readings are academic papers and I took some time to understand them but it is good quality readings.

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.

So far, we have learned about the definition of VR,

how immersion is supported by VR hardware,

and how VR displays and controllers work.

But for most of you, the main question probably remains,

how should you choose a VR device for your VR application?

In this video, I will go through the main considerations for choosing your VR device.

Here is some information,

which shows the market data for VR devices.

So, when it comes to choosing VR devices the first question I would probably ask is,

how do I want to deliver my VR application to reach my targeted users?

Is this something I want to upload to the Internet for

users to download and try out their own devices,

or is it something I will be taking with me

and presenting at exhibitions to reach my clients?

Or is this something I expect clients will come to me for directly?

If it is the first situation,

say, you've made a small game or application,

and you want to have access to the mass market,

you should probably first consider mobile VR because

that's the kind of device most users have.

You could make a game just for

high-end HMD users and upload it to the Oculus store and steam VR,

but this will exclude users with mobile VR devices.

In the second case, for instance,

you have developed a piece of VR artwork you'd like to show in an art exhibition,

or you have invented some new technologies to enhance

the VR experience and you want to bring it to a technical exhibition.

Your best bet is probably a high-end HMD which gives

the actual level of immersion that is needed to fully express and support your idea.

Finally, if you actually expect clients to come to you,

for instance, if you are a therapist and you are using VR for therapy,

or you are a big company which provides

interpreted simulation solutions for all kinds of training,

you probably should have a dedicated area where you have

a full set up with either a high-end HMD or a bespoke cave.

As most of us,

are you one of the first two situations,

I will go into more detail about mobile VR and high-end HMDs.

If you have a specific budget you might want to start with cost.

In order to set up mobile VR,

you will need to buy not only a HMD case, but also a phone.

The price will vary depending on the phone,

but in total will not cost very much.

If you want a better experience than mobile VR you can buy a game console VR.

You will need to buy everything to go with it,

and in total will cost more than the mobile phone.

Or, if you have the budget to go for the high-end VR,

you will have to get the HMD,

the controllers and a high-end PC or laptop with a very good graphics card.

With this, you are going to be spending a significant amount of money.

In this case, you are investing in not only the gear to experience VR,

but also a desktop for your VR application development.

There are technical features to consider too,

including resolution, frame rate,

and how heavy the device is.

In terms of resolution,

you should be looking at resolution per eye,

some places at the resolution from each eye together.

So, the number looks bigger,

but it does not mean the resolution is better.

So, pay actual attention to that.

As you can see, most VR display resolutions are

relatively low compared to standard computer displays.

Hopefully, things will soon improve in this area.

In terms of the refresh rate,

if you really want to push that immersive experience,

the higher the refresh rate the better.

However, refresh rate is not exactly the same as frame rate.

Depending on your graphics card and how demanding your application is,

the frame rate can be a lot lower than the refresh rate you see on the table.

In terms of weight,

all devices are quite similar.

Although PlayStation VR seems to be the heavy one on the table,

it is actually the most comfortable one I have tried.

Finally, there is a table where I put everything together.

I also added the information about tracking and controllers

which we discussed previously.

OK, that's all I have to say about VR devices for now. Happy shopping!
