The user interface has been natural in its evolution and strategically heading towards the 3D-projection holographic interface (3D-PHI) era.
Since its conception (~1960) user interface have been evolving for very much to work intuitively for 3D-PHI. User interface growth and improvements has been consistent with technology, human behaviours and learnings for seamless adoptability for the start of 3D-PHI in near future (~2030).
