Let's see if I can do this justice, without consulting any of my technical advisors... Alex is wearing the touch controllers that Geoff ordered for the Oculus Rift, virtual reality goggles. I can't remember how long ago Geoff contributed to their Kickstarter campaign, but he was, for sure, an early believer. Now, with this new, added gear our experiences in VR are even more heightened, amazing. In this particular scenario, Alex is aboard the International Space Station, and not only is he exploring, but he can manipulate objects around him, and take directions to perform tasks, in space! We can see a version of what he is seeing, on the monitor. It is virtual, but it's the realism that makes this stuff so thrilling.
