IntroductionHeliodisplay 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

Working

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

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 invisible screen

Specifications1024 x 768 resolution, 16:9 or 4:3 aspect ratios.2000:1 contrast ratioSupports all formatsProjects any images that would be viewable

on a computer screen or televisonNo specialized hardware or software3D compatible

AdvantagesNo screen to project imagesDevice is light weight and can be converted into a furnitureNothing is added to air. Nothing affects air quality projected

images and video are two-dimensional, but appear 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 displayTranslucency is controlled by the heliodisplay

DisadvantagesHeliodisplay is very expensiveViewing a Heliodisplay image in direct

sunlight is almost impossibleScreen is essentially air, so it can become

distorted with too much air movement in the room

ApplicationsAdvertising/promotionVideo conferencingVirtual surgery and pre-operative planningMilitary training programsGaming/artworkEngineering/architecture plansBuild the Heliodisplay into furniture

Other Display Systems

Fogscreen

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

ConclusionHeliodisplay has great potential and would be ideal

for collaborative workHeliodisplays is still in the initial stages and the flaws

of cost and environment of positioning will soon be overcome.

Several other thin air-displays are available but heliodisplay outclasses them, because of the attention it draws and its maintainability, and as a result it has more market value

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