You know about VR the mixed reality headsets putting virtual and real together are the next wave.
The Occipital Bridge is an iPhone headset that does both, and it cost $3.99.
In one sense It's a basic VR headset for the iPhone 6, 6s, and 7. But the Bridge also uses Occipital's depth sensing structure camera that kinda works like Google's Tango, or Microsoft's HoloLens.
It can scan a room or objects and map 3D space.
I scan my viola lab and the start walking arround in assimilation, quite trippy.
It sound weird and it is weird but it fells like we are extra positional tracking and I put virtual robots and fake furnitures on it too.
The Bridge supports unity for developers and the depth-sensing camera can detach and work with iPads, too.
It's a kit for exploring mixed reality using an iPhone, and it costs a lot less than a HoloLens.
