The tech industry has been bustling with excitement as new developments in virtual reality emerge. As major tech companies like Facebook and Sony develop their virtual reality headsets, Microsoft has begun to occupy the space of augmented reality. Unlike the Oculus Rift and the Samsung Gear VR, which produce full virtual immersion, Microsoft’s HoloLens allows users to interact with holograms in the physical world. HoloLens crosses the lines of AR and VR by projecting a virtual environment onto the user’s physical space. The applications for this technology could greatly affect anything from neurosurgery to roof repair and would even make Tony Stark jealous.
