Today Microsoft Revealed its Three dimensional Hologram head set,a hologram image changes as the position and orientation of the viewing system and changes in exactly the same way as if the object were still present.
As Microsoft describe on its HoloLens webpage:
There isn’t a screen to touch or a mouse to click. Use gestures to create, shape, and size holograms. Use your eyes to navigate and explore. Use your voice to communicate with your apps. Microsoft HoloLens understands your movements, vision, and voice, enabling you to interact with content and information in the most natural way possible.
