Cours 4 sur 5 dans 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.

Like everything else in VR,

it is important that you test your social interaction application

with participants to really understand whether it works or not.

You should try to test it with those who your app is designed for.

But if the app is designed for a small group of people,

we might have difficulty accessing to them.

For instance, if you are developing a psychotherapy app for

patients with a particular kind of mental health problem,

you should test it with other people first to really

polish your app before moving out to this special group.

After your participant has spent some time interacting with your avatar or agent,

you could get their opinion by giving them a set of questionnaires.

And in the questionnaire,

you should try to use the name or description of

the virtual character rather than the phrase virtual character,

because the phrase, itself,

implies that it is not real.

And some people are more likely to be primed by that phrase and as a result,

rate the interaction is less realistic.

You will want to understand if the plausibility illusion has worked.

For this, you could ask questions such as,

how much did you find yourself behaving as if Christina were

real and how much do you have physical responses,

such as changing heart rate, blushing,

sweating, etc., to Christina as if she were real.

You could also use other questionnaires often used in social psychology.

You could ask questions such as,

do you like Christina?

Do you want to spend more time with Christina?

Do you feel Christina is reliable?

And, do you feel you had a connection with Christina?

In order to fully understand your results,

you might also want to get the participants to answer some questions about themselves.

For instance, their own personality could

have an impact on how they answer these questions.

You could also ask them to comment on their experience directly.

You might want to ask specifically if they

experienced any break in the plausibility illusion.

That is, has there been any times where Christina did something weird,

which reminded them that there was not real.

You can ask them to comment on things that really worked for them.

Were there times where they found the interaction particularly appealing?

You also want to ask if the VR app works for the specific task it is designed for.

If it's a customer service agent,

did you get the information you wanted?

Are you satisfied with this experience?

If it's a collaborative task involving many people,

was everyone involved in the discussion?

Did they manage to agree with each other and are all happy with the result?

A smooth social interaction normally leads to good interpersonal connection, rapport,

and trust so you can test how much participants are willing to

trust the agent or avatar after spending some time with them.

Or you can record their interaction in VR and review it yourself,

or even watch it with the participant and ask them to comment on it.

Looking at what someone does in an interaction is

often a lot more telling than asking them afterwards how they felt.
