HELIODISPLAY

INTRODUCTION

An interactive free space display developed by IO2 technologies.

It is a planar display… ie, 2D not 3D

Works as a free space touch screen..

Eco-friendly , low power consuming and various image and video formats…

HISTORY

Developed by Chad Dyner …

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

Dyner found IO2 technologies to commercialize heliodisplay….

PRINCIPLE AND WORKING

Heliodisplay transforms water in to a unique screen of fine vapour, suspended in mid air to create nearly invisible screen in to which any image can be projected…

This vapour curtain(screen) is sandwiched between layers of clean air to create an acceptable screen…

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

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….

KEY FEATURESNo other additives or chemicals are needed

only plain tap water is necessary..Similar to other display darker the ambience

brighter the image…It do not use holographic technique ,though

both has similarities…

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..

APPLICATIONS

Advertising and promotion, e.g : trade shows, in-store displays ,museum etc…

Collaborative Decision Making e.g. board meeting & presentations, teleconferencing..

Consumer e.g: video games , home theatre

Heads-up display in new fields …..

Simulation & training e.g. virtual targets pre-operative planning etc

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….

Basic prototype of heliodisplay as introduced by IO2 technologies……..

Model with touch screen capabilities included

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…..
