I went searching on the net for information on holographic touch screen technology, i wanted to put to bed doubts as to whether it really existed and was feasible or not in 5 years time... what was being done now? So i looked around and found some really amazing stuff.
1] the technology exists... someone even has a patent out on it. The link for the specs are as follows.

Bit dry and boring but pretty much what it is saying is that touch screen holographic technology exists!
2]I found other peoples applications for the technology... because if there is insufficient interest in a technology it won't get funding or flourish.. this would be a problem. In 5 years time the technology would be the same as it is today, but according to this site they are thinking of marketing applications which is great because that is a great industry motivation to develop a technology to use. The site also has some technical explanations on how it works.

It is more concerned with 3D holographic display.. I'm really only interested in 2D but if 3D is available then i don't see any problem.
There is a bit of an explanation on how it works...
Image display = "The optics module is the heart of OPD's display system. It collects light from a target source inside the unit, then directs the light through the optical system, focusing the light rays in the space out in front of the display. At the point where the light rays converge on the focal point, the optical system creates a 3D image of the object."
Touch Sensor = " The infrared detector scans the plane of the holographic image to detect the intrusion of a finger into the desired portion of those images. It then identifies the selected number or symbol and transmits that selection from the equipment's internal software. Basically, the infrared emitter points at the area of the hologram and tells the kiosk which letter or number was pushed."
Other advantages of the technology is that, "the actual hardware for the system is a sealed box containing a light source, the infrared beam and a plastic 5-by-5-inch plate bearing the image to be projected." So it is very durable as there are no moving parts to become damaged.
I also found some Youtube clips that illustrate the point that it is out there and can be used...

Minority report style 2D touch screen interface
I think that the sensors for this one are based on holographic technology, but the screen is not.
3D holographic touch screen Demonstration
Touch screen interface Demonstration
[The last clip is really long... but interesting]
The last clip is more to do with the interface of using technology but i think that it is still important to put down here as it shows a potential interface for holographic touch screen technology. I can see both of these technologies merging... [if they have not already] and becoming something that is so easy to use and yet really just something intangible.
