What’s HELIODISPLAY ?

Heliodisplay is a

technology used for

displaying images

in mid air.

In Heliodisplay, a projector focuses the image onto a layer of mist in mid-air.

Contd…

Results in a two-dimensional display

that appears to float.

Similar to Conventional Rear Projection

technique.

No physical screen required.

History

Developed by Chad Dyner, CEO of IO2 technologies.

In 2005 US patent office granted Dyner patent for his product (HELIODISPLAY)

Dyner found IO2 technologies to commercialize Heliodisplay.

HEAT PUMP

AIR

Cools it to a level below its

dew point

STORES THE CONDENSED

PARTICLE CLOUD

PROJECTION SCREEN

For creating artificial screens

Screen created by an invisible layer

of fine water vapour

AIR

AIR

Functional Overview

Fine water vapour, suspended in mid

air to create nearly invisible screen.

This vapour 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.

PRINCIPLE AND WORKING

9/16/2012

6

Converts the imaging properties of the airso that the air is taken in, convertedinstantaneously, and then re-ejected out.

Creates a dynamic, non solid particlecloud by ejecting atomized condensatefrom air.

Base Unit :

Projector :

Projector projects the given input on the

newly created invisible screen.

Similar to rear view projector.

Higher quality image delivery output.

Extraction Device : Condensates the air.

Extraction storage : The extracted condensate

is stored in a storage vessel.

Particle cloud

Manufacture : alters the condensate by

mechanical, acoustical,

electrical or chemical

means, or a combination of

these.

Contd…

Particle cloud

delivery device : Ejects the microscopic particle

cloud ( Screen)

EMC system : Controller & sensor together.

adjusts screen density, Velocity,

Temperature, Humidity etc.

optional scan

converter : Converts signals from external

sources to the Processor.

Allows the image to serve as an input/output (I/O)

device .

Physical intrusion within the input detectable space

of particle cloud , such as a user's finger, a stylus or

another foreign object, is recognized as an input

instruction.

Reflected light scattered off the user's finger or other

input means is captured by optical sensor.

HELIOCAST :

Light beyond the frequency response bandwidth of

the sensor is ignored or minimized, for better Noise

immunity.

The space coordinate of intrusion in space where

the intrusion is lit by the functions as a mouse

cursor, analogous to a virtual touch-screen.

controller reads and interprets the highlighted input

data (coordinate) using blob recognition or gesture

recognition software at Processor.

KEY FEATURES

No chemical

additives needed.

Only plain tap water

is necessary.

Darker the ambience

brighter the image.

Do not use

holographic technique.

Contd...

Best visibility within the range.

No special glasses needed.

REQUIREMENTS

Voltage Input : 110V/60 Hz, or 220V/50Hz

Output size : 22" to 42"

Data Sources : PC,TV, DVD, HDTV, Video game

Connectors : VGA, RGB & USB

PC Specifications : at least Pentium III 400MHZ

25MB free disk space

Win2000/XP

Advantages

No screen is required to project images

Light weight and can be used/converted

into a furniture

No chemicals are used.

Nothing affects air quality projected.

Two-dimensional, but gives 3D looks.

Contd…

Heliodisplay does not create fog.

It causes no odour in the air.

can be seen up to 70 degrees off aspect

for a total viewing area of over 140

degrees.

No special glasses required to see the

display.

Heliodisplay system can be used in any

country, regardless of voltage

standards.

Translucency is controlled by the

Heliodisplay.

Disadvantages

Heliodisplay is very expensive

Viewing a Heliodisplay image in direct

sunlight is almost impossible

Screen is essentially air, so it can

become distorted with too much air

movement in the room.

Applications…

Advertising/promotion

9/16/2012

Video conferencing

Virtual surgery &

pre-operative planning

Engineering/architecture plans

Gaming/artwork

E- Learning

Military training programs

Conclusion Heliodisplay has great potential and would

be ideal for collaborative work

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

9/16/2012

17

Heliodisplay is still in the initial stages

and the flaws of cost 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.
