Introduction Heliodisplay is a technology used for 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-air the 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 the the 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.

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.

APPLICATIONS Advertising / Promotions. Video conferencing.

Virtual surgery and pre - operative planning. Military training programs.

Gaming / Artwork. Engineering / Architecture plans.

Build the heliodisplay into furniture.

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 electronic devices are affected.

Translucency is controlled by the heliodisplay.

05/02/2023

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.

Heliodisplay is still in the initial stages and the flaws of coast and environment of positioning will soon be overcome.

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