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.

This is the first part of the medic show, it's called Pinocchio Illusion, and

we have Alice here to help us.

>> Hi.

>> All ready?

>> Yes, so I'm going to introduce The Pinocchio Illusion.

This was reviewed in a very famous paper by James Lackner in 1988, who reviewed

a whole number of different proprioceptive and multi-sensory illusions.

So for The Pinocchio Illusion, I'm going to first ask our two helpers here,

to turn and face this direction.

And in this illusion, Sylvia is only needed for

her nose, and the real subject of the experiment is Alice.

And Alice is going to experience how easy it is for

people to experience a change in the sensation of parts of their body.

So, first of all Alice, I'm going to ask you to use your left hand and

reach out and try to find Sylvia's nose.

Okay, and hold your hand there, and in the course of this illusion,

I'm going to ask you to close your eyes, and I'm going to touch your nose, and

I'm going to touch your finger, is that okay with you?

>> Okay, yep, that's absolutely fine.

>> So then, concentrate on the feeling you get, and

when you start to feel something unusual, just say what you feel.

>> Okay. >> Okay, so I'm going to make sure that

your left hand is not touching any other part of Sylvia, other than her nose.

Okay, so I'm going to take hold of your finger, and I'm going to move your

finger to be touching Sylvia's nose while I'm synchronously tapping your own nose.

Okay, so we'll start now.

And the tapping I'm doing is quite irregular,

it shouldn't be something predictable.

>> It feels like my nose is really long.

>> Can you describe that a bit more?

>> It feels like my left hand is tapping my own nose.

So, it feels like the end of my nose is really far away.

>> Okay, so let me explain what's happening.

So Alice was feeling on her fingertip and nose,

while synchronously feeling on her real nose, my tapping.

So the brain has a contradiction to resolve, which is,

how come my hand is out there and it feels like I'm tapping a nose, and

at the same time, my nose is feeling tapped?

The brain doesn't like contradictions, it likes solutions, and the solution it comes

up with, okay, so my nose is really that long, and that's as simple as it is.
