The Secret of an interactive holographic image? Using water vapor!?

We haven't seen a flying car in 2014 years, but there will be interactive holographic technology soon. Leia Display System (LDS) utilizes light, water vapor, and air, and uses sensors to track the user's movements to achieve interactive holographic images ...

Video, users can use the action of poking, pushing, and so on, and can use gestures to pinch or zoom images like the characters in the movie Minority Report. In the demo video more Cars "break" the use of LDS caused by the image of the curtain, and the attached to the effect, quite lifelike.

So far, LDS has a screen size of 95cm x 65cm and 3m x 2.5m, which can be linked to other larger screens. Polish-based LDS developers say the technology has been used in word signs and advertisements, but many people have used it to create more "unconventional" uses. I hope this technology can be developed to other uses rather than just advertising.
