holographical communication

i've noticed in a car i've been in, that it's actually possible to set the temperature of each side of the car to a different temperature. take this a step (or a few steps) further and you could control where a particular water molecule would appear in the car, or, a whole lot of water molecules.

if, then, you were to shine light on one or many of these water molecules from different angles via multiple projectors in the car, an empty seat next to you could actually appear to be someone sitting in the seat next to you, with water molecules and light shined on to them controlled via the advanced air conditioner in the car.

the recording of what light is supposed to be shined on to which water molecules would be much more easy. simply provide multiple cameras from different angles in the car, measuring how the outline of the water vapour should appear via correlation from 2 (or more) cameras.

of course if i were to be talking to a beautiful woman in the empty seat next to me whilst driving, i would probably be distracted (although, distraction while driving is a serious issue!) so i'd want to have google driving it.

  i just saw it ^
  
  i like the general idea, but i think cars will be driving themselves by the time these holographic systems are incorporated into cars. even then, i believe there will be an option to drive manually, and if i were to choose that option, i think i'd probably still be a little distracted by the beautiful woman in the seat next to me.

Sep 20 2011: Any technologies relying on water molecules floating in the air would be severely hampered by the movements of the air. (Do not breath or open a window)

  Sep 20 2011: indeed i agree that you couldn't open a window, but breathing and _some_ slight movement of air could be compensated for or even partially predicted with pattern recognition.

    Sep 21 2011: My point is that the system is susceptible to too many variables to produce reliable results.
    
    A system that relies on moisture within the air would be utterly complex in attempting to compensate for humidity alone. (Not to mention the tracking of each water molecule to use as a refraction surface)

      Sep 21 2011: that's true. i guess it's up to mathematicians and physicists to create or update existing formulas to make it easier to modify groups of molecules in the air. either that or wait for computers to evolve to a state to handle it even with the sloppiest of coding.
      
      i'd prefer the former to the latter though.
