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 appears to
float.

History
In late 2003, Chad Dyner demonstrated a unique revolutionary
display technology.
Figured out a way to stop in midair the light coming from the
projector.
Used a cloud of microscopic particles.
In 2005, the U.S. Patent Office granted Dyner a
patent for a "method and system for free-space
imaging display and interface".
• Dyner found IO2 technologies to commercialize the
heliodisplay. 05/02/2023 6

Heliodisplay and Screen ProjectorScreen Projector Heliodisplay
• A screen projector display in 2d.
• A support structure (i.e. projection-screen) is used for displaying a projected image.
• All video, images can been seen in 3d, this makes the image more realistic than on a projection screen.
• No screen is required, as the system itself creates an invisible screen in the air and thus projects on that.

How It Works ?
Air Is Drawn In
A Cloud Of Microscopic Particles Is Created
Cloud Of Microscopic Particles Is
Ejected
So As To Create A 3D Screen
Digital Projector Unit Illuminates The Particle Cloud
Creates A Visible Image

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.05/02/2023 13

Heliocast Interactivity
• A handheld object acts as a mouse and drag images in midair.
• Hand movements are monitored by an optical tracking system, which is a camera that:
1. Monitors and locates movements .2. Changes in the location of our hand.

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

AdvantagesNo screen to project images.
Device is light weight and can be converted into a furniture.
Nothing 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.05/02/2023 20

Conclusion• Heliodisplay is a good projection unit.• Heliodisplay has great potential and would be ideal for collaborative work• Heliodisplays 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.
• It does not require any special hardware and support videos and jpg images, flash, quick time etc.
• We can also play games on heliodisplays. • It creates one of the most convincing open-air holographic-like images in
existence.• Heliodisplay can work as a free-space touchscreen when connected to a PC
by a USB cable.05/02/2023 23
