Heliodisplay is a technology used for displaying images in mid air.
Developed by IO2 Technologies
A projector is focused onto a layer of mist in mid-air
Two-dimensional display that appears to float
Introduction
Dark areas of the image may appear invisible, the image may be more realistic than on a projection screen
Heliodisplays use 80 ml to 120 ml of water per hour depending on screen size and user settings
Heliodisplay can work as a free-space touch screen when connected to a PC by a USB cable
With the supplied software installed, one can use a finger, pen, or another object as cursor control and navigate or interact with simple content
Basic UnitsBase UnitProjection Source
Base unit transforms water in to a unique screen of fine vapors, suspended in mid air
Create nearly invisible screen
The vapor screen is a particle cloud
These particle cloud consists of individual micro-droplets ,held together by surface tension
Working
HEAT PUMP
AIR
Cools it to a level below
its dew point
STORES THE CONDENSED PARTICLE
CLOUD
PROJECTION SCREEN
For creating artificial screens
Screen created by an invisible layer of fine water
vapors
AIR
AIR
Now the projector projects the given input on the found invisible screen
No additives or chemicals are needed, only plain tap water is necessary
Operating the device will not change a room`s environment
It causes no odor in the air
Viewing requires no special glasses
The image can also be manipulated by touch
Key Features
•The images are best seen within 70 degrees to either side
•Projected images and video are two-dimensional but appear 3-D•It can project images from all the normal sources like DVD player or PC
•Device is light weight and can be converted into a furniture
•It works on 95-115 or 220-240V VAC
the area onto which the images were projected seems dry to the touch
Translucency is controllable with the Heliodisplay

Applications
Heliodisplay is very expensive
Needs controlled lighting for best working conditions
Images becomes less visible under bright light
Screen can become distorted with air movement in the room
Disadvantages
Fog Screen Prespecta

Heliodisplay has great potential and would be ideal for collaborative work
It could replace the convectional way of viewing images
Heliodisplays is still in the initial stages and the flaws of cost and environment of positioning will soon be overcome
