Join Craig Barr for an in-depth discussion in this video Navigation in VR, part of Unreal: Virtual Reality for Architectural & Industrial Visualization.
- [Narrator] One of the biggest challenges for room-scale virtual reality is moving and interracting with objects that do not actually match the real world. So let's jump into our virtual reality space and take a look at some of our surrounding props and how we can interact with those and also how we cannot interact with those. So here we are in our space and I'm just going to move around within the space here. So something to note, when I'm teleporting around and if I move this, you can see that my collisions are responding with our teleportation which is great, that's exactly what we want.
We wanted to be able to hit the walls, any kind of cabinets or furniture that we have. In fact if I push it too forcefully, It does give me force feedback and it vibrates in the controller to tell me that I'm hitting something. So this prevents me from kind of intersecting through any of the geometry so this works well. Of course that doesn't prevent a person from thinking that something is there and going through it. Because this counter doesn't exist, I can actually pass right through that. Likewise with any of the furniture, even though I have the collision for the teleport thing there, it's easy to forget that this piece of geometry doesn't actually exist.
And that's kind of a neat part about virtual reality, If you can build something to get that far immersed into it then all is fine and well with your design, but it is important to note that collisions are still important when setting up in Unreal so you do have that ability to not intersect with the geometry or landing areas that you don't want your viewer to land in. And this certainly works well with teleportation, if you want to have a space where the collisions are going to block out or eclude someone from visiting an area you don't necessarily want them to go into you can use it to essentially guide a tour virtual reality along.
So there's one of the challenges faced within the virtual reality space. And that is, interacting with objects that aren't actually there.
