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.

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.

Principle and Working

6

7

• 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.

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.

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.

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.

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)

• 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.

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

Model with touch screen capabilities included

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…

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.

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….

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.

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

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.
