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

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.
