If you think you have a sense of what Microsoft's HoloLens headset can do, you're in for a pleasant surprise. The company's Alex Kipman recently presented a TED Talk on HoloLens that included multiple fresh demos illustrating Kipman's vision of an augmented reality future. He showed off virtual caves and forests, and a space where you could watch TV at one moment and talk to family in the next. The highlight, however, comes near the end: Kipman talks to an avatar of NASA's Jeffrey Norris standing on a recreation of Mars. Suddenly, Star Wars' holograms aren't so far-fetched.
