I love Star Trek and I love the idea of holograms or holodecks or virtual reality technology. I would like to know when will we ever have the possibilities of doing this sort of stuff in real life? Is this even possible?
A true holodeck like in Star Trek would be hard and we are not where near that kind of technology. However we are closing in on virtual reality and should have that in about 10 years. We are getting basic VR today.
This is what Ray Kurzweil says about it:
2020
3-D Virtual Reality projected in retina
VR haptics
Cave has been around for years, as have LINK trainers for pilots. If you want to play like a ghost, where there is no tactile feedback, then holodeck style VR already exists on a small scale.
I'm never going to find it again, but I read on the net recently that one of the phone manufacturers is supposedly (grain of salt here) going to add a chip that will give 3D projections on their phones.

I'll wait....
I found a article that talks about it:
New technology may make smartphones project 3D hologram by Christmas 2015
Apparently China has already released one, or at least that's what they're calling it. It looks like it might be sort of 3D-ish, but I'm not sure holographic is quite the word that comes to mind. A shell with 4 cameras can be attached to the phone to track the user's finger movements to allow controls in the air. No more fingerprint smudges on the screen. It's still on a flat screen though unlike that of Star Wars fame.
"Help me Obi-wan Kenobi. You're my only hope!"
The hologram is created using six projectors, which layer light to create an image floating in the air, much like a real and solid object. The discovery came from fusing an image processor with a thin layer of micro LEDs to create the Quantum Photonic Imager. The result is quite remarkable; a projector that is approximately the size of a TicTac candy. The projector is powered by the chip that controls the colour, brightness and angle of each individual beam of light.

Strictly speaking, an LED array is not a true hologram, and it isn't "projected" as many other posters have said. "Projection" means light from a central source is radiated in a pattern to make a display on a wall, screen, or other object which does not emit its own light.
LED's, by definition, *do* emit their own light.
A true hologram is a light baffle that creates the impression of a 3 dimensional object by utilizing diffraction to re-create light waves as they would be coming from the real object.
A truly holographic animation would likely require an array of electro-optic samples, each a few microns on a side at most, that could be independently controlled by external electronics.
Furthermore, quality holograms require laser illumination. Thus a fully holographic animation, in order to avoid colored-smearing or aliasing effects, would need three separate arrays and some system of optics set up to direct each light to its screen: Red, Green, and Blue.
The electro-optic array is the tough part, everything else is standard optics. I figure a modified circuit board could do the trick potentially, although to my knowledge no one has actually bothered to build any.
A 3-d animation in mid-air can be done, however, it is monochromatic just like old-school movies:
