In this course, we want you to learn how to create virtual reality interactions but you can't learn it just by listening to us. You have to do it yourself and consequent to that we're going to get you to do a project as part of this course and I'm going to talk you through some of the requirements of the project with a little example I've created. So this is a basic VR environment and the first kind of requirement, is that you have a VR environment that represents a space. So if you followed our lessons on creating a virtual environment then you will already have an environment something like this. And another requirement is that you give a brief description of it and give some instructions about what to do with the environment and that's the leading key this time because this course is all about interaction, so you need to be able to interact with the environment. And so I'll show you a couple of examples of interactions. If I look at the books all of the interactions in this course are gaze based. If I look at the book over there, it suddenly appears in front of me and I can click to drop it. And I've also got navigation so I can move around this environment. If I look at that circle on the floor that's a teleport target and I will move around and I will teleport to a new place as you can see I'm in a new place in the whim. And if I then look at this door behind me which I can make it open and shut. So lots of the objects in this environment responds to my gaze so this is all using gaze based interaction. That's not essential for this course but it's the form of interaction that will work on most headsets. So I just turned on the television by mistake if I look at the TV, it will make some sound or not make some sound just look at it to turn it off again. So all of the interaction is gaze based so that means we can learn almost every kind of headsets from Google cardboard light up to high end headsets. But you could use controllers if you like but be aware that if you use controllers, you will have to someone market who also has a suitable set of controllers so it might take a bit more time for your coursework to be marked because all marked by your peers other students. But the essential thing is that we have this interaction and as you can see in this environment I have two types of interaction, I have had navigation so if I look at one of the teleport targets, I will move around and I have objects interaction. So if I look at this book I will pick it up and it disappears again. So those are two basic types of interaction you need in this project. In the first, work in progress, we can ask you to do just the navigation but by the end of the project we will also want you to be able to interact with objects. So that's your project. This is what I've made. I'm really looking forward to seeing what you make and I hope it's going to be see some really exciting work, some really exciting interactive VR environments.
