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. Hi-Tech projector that display pictures in the air. An interactive free space display developed by IO2 technologies. It is a planar display i.e. 2D not 3D. Works as a free space touch screen when connected to PC. Eco-friendly , low power consuming and various image and video formats. 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.

4. 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.

6. 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.3/9/2017 6

Heliodisplay and Screen Projector
Screen 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.

12. 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

13. 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.3/9/2017 13

14. • 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.

15. 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.
3/9/2017 15

16. Cont....
• Images 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.

3/9/2017 19

20. Advantages
 No 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.3/9/2017 20

21. Cont...
 Heliodisplay can be used in any country since it works on 95-
115 or 220-240 VAC.
 Heliodisplay, imagery can be seen up to 75 degrees off aspect
for a total viewing area of over 150 degrees.
 No special glasses required to see the display.

22. Disadvantages
• Needs controlled lighting for best working conditions.
• Images becomes less visible under bright light.
• Wind and bright light interferes with image visibility.
• Expensive.

23. 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.3/9/2017 23
