Introduction Heliodisplay is a technology 

used for displaying images in

mid air.

In the heliodisplay, a projector

focuses the image onto a layer

of mist in mid-air, resulting in

a two-dimensional display that

appears to float.

Working

The device converts the imaging properties of the air so that theair is taken in, converted instantaneously, and then re-ejectedout

The system thus creates a dynamic, non solid particle cloud by ejecting atomized condensate present in the surrounding air

Now the projector projects the given input on the found invisiblescreen

Advantages No screen to project images Device is light weight and can be converted into a furniture Nothing is added to air. Nothing affects air quality 

projected images and video are two-dimensional, butappear 3D since there is no physical depth reference Heliodisplay does not create fog, so no electronic devices in

the room are affected Heliodisplay can be used in any country since it works on

95-115 or 220-240 VAC Heliodisplay, imagery can be seen up to 75 degrees off 

aspect for a total viewing area of over 150 degrees No special glasses required to see the display  Translucency is controlled by the heliodisplay

Disadvantages Heliodisplay is very expensive

 Viewing a Heliodisplay image in direct sunlight is

almost impossible Screen is essentially air, so it can become distorted

 with too much air movement in the room

Fogscreen

Fogscreen is a display surface made out of a cloud of water vapor diffused into the air as a very dry fog

Conclusion Heliodisplay has great potential and would be ideal for

collaborative work

Heliodisplays is still in the initial stages and the flaws

of cost and environment of positioning will soon beovercome.

Several other thin air-displays are available butheliodisplay outclasses them, because of the attention

it draws and its maintainability, and as a result it hasmore market value

Its various applications such as in advertising, a boardroom etc suggests that its future scope is very bright.
