A team of researchers from Brigham Young University have been advancing hologramic technology in pursuit of screen-less holograms. Holograms that are suspended in 3D space and able to be projected in relation to objects in the real world.
Right now these holograms are limited in size and dimensions by the fixed volume drawing area for the lasers – (Optimal Trap Display). With the pace and direction of this research, person sized holograms using this research may be a real possibility in our life-times.
