The Microsoft Build conference starts this week, and I expect that we’ll be learning more about the HoloLens as well as Microsoft’s Windows Mixed Reality operating system. Microsoft has been evangelizing about virtual reality the past couple of years now, and I had a chance to catch up with Microsoft Technical Evangelist Kat Harris at PAX West last Fall. She’s been teaching VR 101 development courses at different conferences, and we talk about what she’s been telling game designers about maintaining presence, building immersive experiences, and how to deal with some of the biggest breakers of presence including VR locomotion and the uncanny valley. We also discuss the limits of virtual reality when it comes to haptics, uncanny narrative, the future of artificial intelligence in enabling collaborative role-playing, and the power of world building & storytelling in games like Minecraft.
