课程 1（共 5 门，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.

As we touched on briefly before,

another big problem in VR interaction is haptic feedback.

VR displays are now very good at tricking us

into thinking that virtual optics are really in front of us.

But our ability to interact with them in a naturalistic way is still quite poor.

Thanks to the tracking technology and

the vibration feedback that current VR controllers provide,

we can use them to select and manipulate virtual objects.

However, in order to really do this in a naturalistic way,

we would need VR gloves.

Instead of holding on controller and pressing a button to grab objects,

we should be able to just grab them with our hands.

There are a few VR gloves available which are

all well integrated with current VR displays.

But in order to really grab

a virtual object and feel that we are holding something in our hands,

ideally the VR gloves should be able to give force feedback.

These are normally called exoskeleton VR gloves,

as they rely on an external skeleton outside of the glove to support force feedback.

There are a couple of bodysuits I have seen at

VR exhibitions which provide both force feedback and tactile feedback.

They are mainly designed for game play,

so when you're being punched by your opponent,

you actually feel the force of that.

I'm not sure I would want that,

but I can imagine they could become quite popular with gamers.

In summary, the current VR controllers are more like a borrowed concept from

2D user interfaces and do not really support

VR interactions in the 3D space in a very naturalistic way.

I believe we will soon see VR gloves in the consumer market,

some with beauty in force feedback,

so maybe soon enough,

you will be able to shake hands with someone virtually.

For hardcore gamers, a full body VR suit could be something to look forward to,

which will make gaming more immersive.

However, certain challenges in haptic feedback,

such as tactile feedback,

or the feeling of gravity when holding an object,

remain unsolved for now.
