What does it mean to have holograms on Windows 10?

Windows 10 is the first platform to support holographic computing with APIs that enable gaze, gesture, voice, and environmental understanding on a self-contained device. With Windows 10, holograms are Universal Windows platform apps, and all Universal Windows apps can be made to work as holograms. Holograms in Windows 10 will lead to entirely new ways for us to communicate, create, and explore.
