When its mixed reality headset was first announced, Microsoft touted its ability to lend a hand in a variety of enterprise scenarios. The company teamed up with NASA for Sidekick: a project that is putting HoloLens on the International Space Station to give virtual aid to astronauts. The project uses the tech in two ways to offer support a crew member wouldn't ordinarily have while completing a task. First, Remote Expert Mode uses Skype to give someone on the ground a view of exactly what the astronaut is seeing. From there, a colleague can remotely guide the task or scribble notes and drawings in the astronaut's view -- all in real time. A Procedure Mode overlays animated holographic illustrations on top of real objects for reference. Not only could this cut down on training time, but it could provide a valuable guide in situations plagued by communication delays.
