The issue of how to navigate space in virtual reality is an important one. Do you create a weird treadmill style set up? Do you simply use a controller? Why not just create an actual real life room, then build that same room, to the precise same specifications, in the virtual world, then allow people to explore that space? That'd be one (crazy) solution.
This is precisely what Zero Latency is attempting to do with its Inversion VR system. It uses a series of tracking cameras to help create a virtual space that players can actually navigate. Pretty incredible.
You can see the results above.
Interestingly Zero Latency is actually showing its Inversion VR system in Melbourne next weekend, as part of the Pause Festival. If you can make it to the event, you sure as hell should be checking this out.
