课程 4（共 5 门，Specialization Virtual Reality）

Meeting another person is one of the most amazing experiences you can have in Virtual Reality. It is quite unlike communicating through any other medium except a real life face-to-face conversation. Because the other person is life size and shares a virtual space with you, body language works in a way that cannot be done on a flat screen. This course will enable you to create realistic social interactions in VR. You will learn about both the psychology of social interaction and the practical skills to implement it in Unity3D. We will take you through the basics of 3D character animation and how to create body language. You will learn about how to make characters that can respond to players’ speech and body language. You will also learn about avatars: the virtual representation of other players, and agents: computer controlled NPC characters and how to implement both of them. As many people have said before us, social is the future of VR. This course will help you become part of the future of Virtual Reality social experiences.

The way we use space is also very important for social interaction.

Being close together, while talking is very different from being far apart.

One of the big advantages of social interaction in VR as opposed to that on

the flat screen is that we share the same virtual space with the other person so

that all of the spatial relationship works.

>> Proxemics is the technical term for the use of space and

distance in social interaction.

It was introduced by Edward Haul who also defined the social meaning of how far we

are from someone else.

The furthest distance is public space.

At more than about 3.5 meters or

12 foot, this is the distance at which strangers pass each other in public.

This is normally too far to have a proper conversation.

>> Social space is closer than 3.5 meters or 12 feet, but more than a meter.

Unless we're packed in a crowded train carriage, if we're this close to someone

else, it normally means we're going to interact with someone socially.

And this is the comfortable distance for talking.

>> If we get closer than about a meter or four foot we enter personal space.

At this distance interaction starts to be uncomfortable and too intimate.

We generally avoid getting this close in normal interaction.

If we have to be this close we normally compensate by looking

at each other less to maintain a bit more social distance if not physical distance.

>> So it is very important that virtual characters maintain the appropriate social

distance and should move forward and

backward to compensate where the user moves.

Moving into personal space can also be a very powerful signal in a virtual

character, including a sense of intimacy or threat.

I ran an experiment in which a female character was talking to male participants

when she moved forward into their personal space,

their heart rate went up, showing that they had a strong emotional impact.

>> Another aspect of space in social interaction is the direction in which we

are facing.

In a normal conversation, we face each other.

If I was talking to Sylvia, we'd stand like this.

But if there was a third person, if you want to include you, the learner,

we might stand at a 45 degree angle.

>> We would also do this if, instead of simply talking,

we both are looking at something.

Maybe something we're working on together.

And this is called shared attention.

>> If we aren't at the right distance and

facing the right direction social interaction can just feel wrong.

That is why it's really important that our characters take account for proxemics and

stand in social space facing the player.

If nothing else it's a really strong signal that they're paying attention.
