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.


4/20

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.


8/20

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.


9/20

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.


10/20

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.

13/20

APPLICATIONS

Advertising / Promotions.

Video conferencing.

Virtual surgery and pre - operative

planning. Military training programs.

Gaming / Artwork.

Engineering / Architecture plans.

Build the heliodisplay into furniture.


14/20

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.


15/20

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.
