INTRODUCTION
INTERACTIVE PLANAR DISPLAY DEVELOPED BY CHAD DYNER PRODUCED & MARKETED BY IO2 TECHNOLOGIES

REAR PROJECTION
 In-camera special effects technique in film production Widely used for many years in driving scenes TECHNIQUE Actors stand in front of a screen A projector positioned behind the screen casts a reversed image of the background A major advance over rear projection is FRONT PROJECTION Examples ‡ James Cameron - Aliens ‡ Austin Powers film series

WORKING
Projects images onto a screen of microscopic particles. Microdroplets 1-10 microns in diameter. Optical tracking system for monitoring hand movements.

WORKING contnd System creates a dynamic, non-solid particle cloud by ejecting atomized condensate A heliodisplay runs on particles present in the air Particles in the air are converted into nearly atom-sized particles, and are re-emitted upward Held together by surface tension and form a cloud Changing the molecular properties-qualities of the image, like brightness and sharpness, can also be changed

HELIOCAST INTERACTIVITY

When the Heliodisplay is connected to a PC using a standard USB cable, and with the supplied IO2 Heliocast software installed, you can use your finger for touchscreen control to navigate and interact with content such as drag & drop, clicking, double clicking etc as one would on a standard PC.

MODELS
M1
The original M1 units produced by IO2 were advanced prototypes and proof-of-concept, but a few were sold to early adopters through channels such as eBay.

M2
The second-generation M2 Heliodisplay supports a 30" image with 16.7 million colours and a 2000:1 contrast ratio. The interactive M2i version includes virtual touchscreen capability.

MODELS contnd M3 and M30
Third-generation M3 version launched on February 28, 2007 Has the same basic specifications as the M2,but is said to be much quieter, with improved brightness and clarity More stable operation with an improved tri-flow system. Standard ratio of 4:3 in addition it also displays 16:9 widescreen ratios. There is also an interactive version called the M3i. The M30 is the updated version of the M3,30 designating the diagonal screen size.

MODELS contnd M50 and M100

In late 2007, IO2 Technology introduced two larger Heliodisplays, the M50 and M100. The M50 has a 50" diagonal image The M100 has a 100" diagonal image(about 2 meters tall).

FEATURES contnd Interactive version of the Heliodisplay (M2i) allows a finger to act as a computer pointing device User can interact with floating images or video M2i comes with Heliocast software

 Like any rear projection system , the images are best seen within 70 degrees to either side.

still quite an expensive toy ,not everyone can afford it If you want to buy it Heliodisplay M2: $18,100 Heliodisplay M2i: $19,400 If you rent it for 1 week 2 weeks Heliodisplay M2 $9,600 $13,800 Heliodisplay M2i $12,800 $14,800

FOG SCREEN
 Finnish company FogScreen has begun volume production of its unique walkthrough projection screen.  The FogScreen Inia screen projects high-quality images onto a thin laminar air flow of water vapour.  The FogScreen feels wet and cool to the touch  Creates an effect of the computer generated images floating in thin air Can be used in the development of special effects displays and airborne advertising media, walk-through or drive-through posters ,as a high impact advertising medium in malls, airports and mass audience events.

PERSPECTA
 Actuality Systems, Inc. has developed an incredibly high performance threedimensional display nearly 100 million voxels and interactivity at your fingertips.  Professionals in pharmaceutical design, MCAD, and medical imaging can see data floating inside of the clear viewing dome.  Your volumetric imagery can be viewed from any angle, without cumbersome goggles.  it is mainly used for medical purposes.

ADVANTAGES
Other companies have developed similar technologies .A Finnish company, FOGSCREEN, has developed a machine that creates an image in midair by projecting an image onto a screen of water vapour between two layers of air It can be touched, and even walked through  Uses water vapour, so touching the screen feels wet  fog screens are not yet interactive. ACTUALITY SYSTEMS, has created a true 3D image that floats in midair,PERSPECTA  This image is enclosed and of a lower resolution than a heliodisplay.

DISADVANTAGES
Screen is essentially air, so it can become distorted with too much air movement in the room. The contrast ratio of the heliodisplay is not that good compared to the modern day plasma or LCD TV s

FUTURE ENHANCEMENTS
Two main problems of the heliodisplay technology are the contrast and the flickering. Future models are being developed which will be free from these defects. Furthermore a mobile-sized heliodisplay is being developed.

APPLICATIONS
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. Consumer, e.g.: video games; home theatre.

APPLICATIONS contnd 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.

CONCLUSION
The heliodisplay is a relatively new technology and is still being developed. Though it has some flaws the attention that it brings is enormous. Its various applications such as in advertising, a board room etc suggests that its future scope is very large. Several other thin air-displays are available but heliodisplay out classes them and as a result it has more market value. Many people are still skeptical about the extent to which this product can be used: some have even dismissed it as an interesting but useless piece of technology.
