3. Introduction
• 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.

4. History
• Displaying an image using conventional projectors
requires a non-transparent medium, like-screen,wall.
• Developed by Chad Dyner .
• In 2005 US patent office granted Dyner patent for his
product (HELIODISPLAY).
• Dyner found IO2 technologies to commercialize
heliodisplay.

7. Cont…
• A heliodisplay runs on particles already present in the
air.
• Particles in the air are converted into nearly atom-
sized particles, and are re-emitted upward through a
dozen metal plates.
• These particles are held together by surface tension
and form a cloud that can act as a screen.
• By changing the molecular properties of this
cloud, the qualities of the image, like brightness and
sharpness, can also be changed.

9. Cont…
• Heliodisplay transforms water in to a unique screen
of fine vapor, suspended in mid air to create nearly
invisible screen in to which any image can be
projected.
• This vapor curtain(screen) is sandwiched between
layers of clean air to create an acceptable screen…
• The vapour screen is a particle cloud created by
passing the surrounding air through a heat pump
which in turn cools the air to a level below its dew
point.
• These particle cloud consists of individual micro-
droplets ,held together by surface tension.

10. • Other companies have developed similar
technologies that project images in different
ways.
• A Finnish company, FogScreen, has developed a
machine that creates an image in midair by
projecting an image onto a screen of water vapor
between two layers of air, which protect the fog
from external air movement.
• Like the heliodisplay, it can be touched, and even
walked through.
10

11. • However, the FogScreen has its limitations.
FogScreens use water vapor, so touching the
“screen” feels wet. Heliodisplay screens are
air, and they feel dry. In addition, FogScreens
are not yet interactive, although researchers
are working to implement interactive
technology.

13. Models
• M1
- The original M1 units produced by IO2 were
advanced prototypes and proof-of-concept, but a few
were sold to early adopters.
• M2
- The second-generation M2 Heliodisplay supports a
30" image with 16.7 million. The interactive M2i
version includes virtual touchscreen capability.
13

14. • M3 and M30
- The new third-generation M3 is said to be much
quieter, with improved brightness and clarity and
more stable operation with an improved tri-flow
system.
• M50 and M100
- The M50 has a 50" diagonal image, equivalent to
displaying a life-size head-and-shoulders person.
- The M100 has a 100" diagonal image, equivalent to
displaying a large full-body person (about 2 meters
tall)

15. • Models
-M1:
M1 units produced by IO2 were advanced prototypes
-M2:
The M2 Heliodisplay supports a 30" image with 16.7 million colours
and a 2000:1 contrast ratio.
-M3 and M30:
M3 has the same basic specifications as the M2 but is much
quieter, with improved brightness and clarity and more stable
operation with tri flow technology. The M30 is the updated version
of the M3
-M50 and M100:
The M50 has a 50" diagonal image, equivalent to displaying a life-
size head-and-shoulders person and the M100 has a 100" diagonal
image, equivalent to displaying a large full-body person.

16. Basic prototype of Model with touch
heliodisplay as screen capabilities
introduced by IO2 included
technologies……..

17. Key Features
• Life-Size interactive images floating in air.
• No other additives or chemicals are needed only plain
tap water is necessary..
• Similar to other display darker the ambience brighter
the image…
17

18. 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.
• Turn on and off with one click
• Pass objects, people through the image.
• L-90 can be placed on the ground upright or on a
desktop.
18

19. Negative Aspects
• Needs controlled lighting for best working
conditions..
• Images becomes less visible under bright light
• Wind and bright light interferes with image visibility..
• Expensive….
19

20. Proposed applications for the
real-world Heliodisplay include:
• Advertising and Promotion, e.g.: trade shows; in-
store displays; museum, movie and casino displays;
theme parks.
• Collaborative Decision Making, e.g.: board meetings
and presentations; air-traffic control; military
command and control; architectural and engineering
design; teleconferencing.
• Simulation & Training, e.g.: virtual targets; pre-
operative planning; virtual surgery.
20

21. Cont…
• Consumer, e.g.: video games; home theatre.
• Heads-up displays in new fields, e.g.: a patient's vital signs
could hover above the chest during open heart surgery.
• Build one into a door jamb and have a walk through image or
virtual privacy screen.
• An in-store end cap advertising display and demonstration
through which the customer can reach and grab shown
product.
• Build the Heliodisplay into furniture, e.g. project from desk
21

22. Conclusion
Heliodisplay is a good projection unit which does
not require any special hardware and support videos
and jpg images ,flash, quicktime etc..This unique
technology, developed by a former architect ,creates
one of the most convincing open-air holographic like
images in existence.
