An anonymous reader writes: At its Build 2015 developer conference [Wednesday], Microsoft announced the Windows Holographic Platform. In short, the company will let developers turn Windows 10 apps into holograms for HoloLens. On stage, Microsoft showed a Windows video app that you can simply control with your voice: Just say "follow me" and the video app moves along as you walk around a room. "Every single universal Windows app has these capabilities," said Alex Kipman, technical fellow for the operating system group at Microsoft. Apps can look like little windows, or they can be more than that. The demo included a photos app, a browser, Skype, a holographic Start Menu, and even a dog on the floor.
