Holographic user interfaces are at the intersection of two technology trends, augmented reality and virtual reality.
The core concept is quite simple. You map a 3D computer generated world onto the real world. It means that you will see in your real world, objects, creatures or humans that are not actually there. When the virtual world merges with the real world it looks like a hologram. This is where the term "holographic interface" comes from.
What make the introduction of holograms interesting is the interactions we will have with them. The objective is to interact with the virtual world as in the real world, knowing that the virtual world will have an edge, as its free of material and physical contraints enabling "Magic" to happen.
Is this the future of how humans will interact with each other, the world and machines?
