INTRODUCTION
Heliodisplay is a technology usedfor displaying images in mid air.
Invented by CHAD DYNER .
In the heliodisplay , a projector focuses
the image onto a layer of mist in
mid air, resulting in a two dimensional
display that appear to flat.

HISTORY
In late 2003, CHAD DYNER demonstrated a
unique revolutionary display technology.
Figured out a way to stop in mid-airthe light coming from the projector.
Use a cloud of microscopic
particles.
Dyner found IO2 technologies to
commercialize HELIODISPLAY.

PRINCIPLE
Frustrated total internal reflection (FTIR)
Contains an IR camera and a IR light emitting diode.
The internal reflection of IR-light, is interrupted as
soon as a finger touches the acrylic surface.
The images that are generated by the camera
contains white blobs.
HELIOCAST to interactively control the displayed
images.

WORKING OF HELIODISPLAY
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.

The vapour screen is particle
cloud created by passing the
surrounding air through heat
pump which in turn cools thethe air to a level blow its
dew point.
These particle cloud consists
of individual micro- droplets
held together by surface
tension.

FEATURES
No other additives or chemicals are
needed only plain tap water is
necessary.
Similar to the display darker the
ambience brighter the image.
It does not use holographic technique ,though both have similarities.

FEATURES (CONT.)
The image can be seen up to
75 degrees off aspect similar to
LCD screen.
Viewing requires no special glasses or
any other background or foreground
screening.

ADVANTAGES No screen is required to project images.
Device is light weight and can be converted into a
furniture.
Nothing is added to air. nothing affects air quality.
No special glasses are required to see the display.
Heliodisplay does not create fog, so no electronicdevices are affected.
Translucency is controlled by the heliodisplay.

NEGATIVE ASPECTS
Needs controlled lighting for best working
conditions.
Images become less visible under bright light.
Wind and bright light interferes with image
visibility.
Expensive (above Rs. 7,00000).

CONCLUSION
Heliodisplay has great potential and would be
ideal for collaborative work.
Heliodisplays is still in the initial stages and theflaws of coast and environment of positioning will
soon be overcome.
Its various applications such as in advertising, aboard room etc suggests that its future scope is
very bright.
