Anyone who has watched the movie Iron Man or Avengers would be familiar with floating displays especially during the scenes which involve Robert Downey Jr explaining quantum physics. Well, the floating display employs a technique named as Heliodisplay which is an air based display using air that is already present in the operating environment to project things into thin air.
Founded by IO2 technology in the year 2001 the entire concept of Heliodisplay revolves around the fact that it has a projection unit which focuses multiple layers of air and dry micron size atomized particles in mid-air, which results in a two dimensional display that appears to float. The uniqueness of the entire concept lies in the fact that it is similar in principle to the cinematic technique of rear projection and can appear three dimensional when using appropriate content. Also, it allows for multiple viewing and dual viewing when combined with two light sources. With the required software installed one can use a finger, a phone as cursor control and interact with simple content.
In simpler terms the technology which allows you to leave the image suspended in air is termed as Heliotechnology. Trademarked by IO2 technology under the name “heliodisplay”; the technology can receive input from a computer, television or even from video game consoles, and project the image on a floating screen of air thereby giving the appearance of a floating, holographic 3-D image.
The entire idea of floating displays revolves around the fundamentals of electronics and thermodynamics and the screen itself is created by particles that are already present in the room. Chad Dyner, the inventor of the product, explaining the mechanics of his invention remarks that the machine creates a temperature difference in the air directly above the machine, thereby causing condensation in the air. Subsequent to this, a laser is then used to project images onto the screen of condensing air above it.
