The Heliodisplay is a free-space display developed by IO2 Technology. A projector is focused onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float. As dark areas of the image may appear invisible, the image may be more realistic than on a projection screen.

The air-based system is formed by a series of metal plates, and the original Heliodisplay could run for several hours although current models can operate continuously.[1] 2008 model Heliodisplays use 80 ml to 120 ml of water per hour, depending on screen size and user settings, although the medium is primarily air.

The Heliodisplay was invented by Mr. Dyner, who built it as a five-inch prototype in 2001 before patenting the free-space display technology, and founding IO2 Technology LLC to further develop the product.

The Heliodisplay is sold directly worldwide by IO2 Technology

[edit]M1The original M1 units produced by IO2 were advanced prototypes and proof-of-concept. These are the first Heliodisplay developed by the IO2 technologies. They have all the above said properties. But they have less fidelity. This first generation Heliodisplay supports only a 22” image.

[edit]M2The 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.

[edit]M3 and M30The new third-generation M3 version launched on February 28, 2007 [2] has the same basic specifications as the M2 but is said to be much quieter, with improved brightness and clarity and more stable operation with an improved tri-flow system.

Apart from displaying at a standard ratio of 4:3 in addition it also displays 16:9 widescreen ratio. There is also an interactive version called the M3i.[3]

The M30 is the updated version of the M3, which fits into the current model numbering system, 30 designating the diagonal screen size.

[edit]M50 and M100In late 2007, IO2 Technology introduced two larger Heliodisplays, the 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)

hers) IO2 Technology intros floating M3 Heliodisplay screenBy Darren Murph   posted February 28th 2007 5:33PM

We've seen some pretty far-out display creations, and while some are admittedly more useful than others, having our own Star Wars-esque floating display has been a dream for quite some time. Thankfully a company is bringing the idea to life and to more markets than ever before, as IO2 Technology has unveiled a new 3D Heliodisplay worldwide. While the mid-air projector, as it's so aptly dubbed, had been seen a time or two before, the new M3 / M3i boasts "an improved tri-flow system for increased image stability and uniformity," enhanced brightness and clarity, a 1,024 x 768 resolution, 16:9 or 4:3 aspect ratios, 2000:1 contrast ratio, VGA / S-Video / composite inputs, USB, NTSC / PAL compatibility, and "significantly quieter operation" to boot. Marketed to the uber-wealthy and board room runners who'd like to teleconference on a free-space device (and blow the minds of clients), the basic M3 is available for a stiff $18,400, while the M3i -- which also serves as a "computer input device for cursor control in a desktop environment" -- will set you back $19,400.

Floating in midair, an image hovers above a seemingly ordinary table. This unique technology, developed by a former architect, creates one of the most convincing open-air holographic-like images in existence. This article will cover the technology and its future applications.

In late 2003, a small company from the San Francisco Bay Area demonstrated a unique revolutionary display technology. The (then) prototype device projected an image in thin air just above it, creating an illusion of a floating hologram, reminiscent of the famous scene from 'Star Wars' in which R2-D2 projects a hologram of Princess Leia. 

The development of this distinctive technology, dubbed Heliodisplay by its developer Chad Dyner, began early this decade after Dyner decided to trade a promising career as an architect to become an inventor. Dyner bought an ordinary digital projector, took it apart, and spent entire days trying to figure out a way to stop in midair the light coming from the projector without engaging a traditional screen. Though the details are kept a closely-guarded secret, Dyner was willing to provide a general description of the way the Heliodisplay works.  

 

Fogscreen display (Credit: Fogscreen.com)

Displaying an image using conventional projectors requires a non-transparent medium, typically

Page 5: heliodisplay 2

screens, walls, or even water, but air, which is transparent, cannot be used. A more recent development is the FogScreen, which creates an image in midair by employing a large, non-turbulent airflow to protect the dry fog generated within from turbulence. The result is a thin, stable sheet of fog, sandwiched between two layers of air, on which an image can be projected and even walked through. The Heliodisplay creates a similar effect, but, instead of fog, it uses a cloud of microscopic particles whose specific nature is one of the secrets Dyner keeps close to the vest. In 2005, the U.S. Patent Office granted Dyner a patent for a "method and system for free-space imaging display and interface". Apparently, the Heliodisplay creates a particle cloud by passing the surrounding air through a heat pump, which in turn cools the air to a level below its dew point, where it condensates, and is then collected to create an artificial cloud. The particle cloud is composed of a vast number of individual micro droplets, between 1-10 microns in diameter, too small to be visible to the naked eye, held together by surface tension. The focus and illumination intensity of the projected image can be controlled by changing some of the cloud's properties, enabling a sharper and brighter image. 

 

Heliocast - interactive Heliodisplay

Since 2003, IO2 Technology, the California-based company Dyner founded to commercialize his invention, began selling his device under the brand name Heliodisplay M2 for just under $20,000, out of reach of most consumers. IO2 Technology is actually marketing the M2 to corporate customers who would use the device as a novel way to display the company's logo or as a strikingly impressive advertising and promotional tool for exhibitions.  

 

Actuality Systems' Perspecta true 3D display

The M2 projects its 76.2 cm (30'') diagonal floating image at a height of 71 cm (28") above the projector. The native resolution of the M2 is 800 x 600 though it can support up to 1280 x 1024, and the image can be viewed from as much as a 150 degrees angle. The M2i model includes a

Page 6: heliodisplay 2

proprietary system, called Heliocast, for interactively controlling the displayed image. A sensor inside the M2 identifies the movement of the user's hand in the area of the projected image and the Heliocast software calculates the movement of the object projected.

TFOT recently covered another unique display technology, called Perspecta, developed by Actuality Systems. Unlike the Perspecta, which is a true 3D display capable of showing a 3D object perceived when simply walking around the display, the M2 displays a 2D image in midair, creating the illusion of depth. While the Perspecta is currently used mainly for medical and research purposes, the M2 is intended primarily for corporate use as a promotional or advertising tool at this stage. Although it is possible to view movies or play games on the M2, Dyner admitted that the current device is not intended for serious applications such as CAD (computer-aided design). The Perspecta is an enclosed device with lower resolution but with the capability to display a full 3D image and video with almost no flickering or wavering effects. A future display might incorporate the best of both worlds: an open-air display with high resolution, clear 3D capability, along with an accurate interactive capability.

Interview with IO2 Technology

To learn more about Heliodisplay technology, TFOT interviewed its inventor, IO2 Technology CEO, Chad Dyner.

Q: Would you explain how your Heliodisplay works?A: The Heliodisplay transforms ambient air using a proprietary multi-stage system of modifying the optical characteristics within a planar region in which polychromatic light is scattered on this surface such that the image appears visible to the viewer. An advanced optical tracking system monitors finger movement within in the image region and is translated into cursor control movements, enabling the Heliodisplay to be utilized both as an Input & Output device in two-dimensional space. Hence I/O two technology. 

 

 

Q: How much energy does the Heliodisplay projector require and is there a chance we'll see a portable (smaller) version any time soon?A: The Heliodisplay currently utilizes about as much energy as a larger format video projector or computer tower - 350 Watts. These specifications are available on our website. We have built smaller Helios for a select group of corporate customers for various applications and those have been as small as a lunchbox.

Q: It seems that the two main problems of the Heliodisplay technology are the contrast and the flickering. How do you plan to counter these problems? A: Heliodisplay images do not flicker as you mentioned, but they do waver since images are projected into continuously moving air. As the current version is not intended for serious application (e.g., CAD), this is not a limitation. We are, though, working on improving the quality and the current version, which has already delivered results superior to the previous systems.

Q: Is the refresh rate fast enough to watch movies on the Heliodisplay?A: The refresh rate is 30fps. We've watched the movie "The Hunt for Red October" with the US

Page 8: heliodisplay 2

Navy. While you can watch movies, the M2 is not designed for this application as it is for corporate customers and media.

Q: Is it possible to play games on the Heliodisplay, and do you intend to introduce games that use the input technology of the Heliodisplay?A: You can play games on the Heliodisplay, but the picture quality would work for only certain types of games today. This is not to say that with a future version this would not be more widely adopted.

Q: In the 2005 patent application you suggest the concept of two separate Heliodisplays that project images to two different viewers (a concept similar to that shown in the 1983 James Bond film "Never Say Never Again"). Are you working on such a solution or some other gaming/arcade model?A: We have various technologies, some of which are publicly available in patents, others which are not disclosed. We have a military section, for example, in which we do not disseminate anything other than our contact. We have been requested to build a dual-viewing Heliodisplay as in the James Bond movie you are referring to, but yet to have a client who absolutely needs this to go ahead.

Q: Another concept mentioned in the 2005 patent was the cell phone-sized Heliodisplay. When do you predict such a technology to become commercially available?A: There is no estimate for this. I would say at least a decade, maybe more, and it would probably not be using the current system that is commercialized today.

Q: What is the status of the product and what is its present price range?A: Heliodisplays are now being sold worldwide, and in the US, priced well below the twenty thousand dollar mark.

Q: What do you see as the Heliodisplay's biggest potential market and what do you think

Page 9: heliodisplay 2

of the product for the end user/home market?A: The M2 is intended for corporate customers, not for home use. However, IO2 has sold a few Helios to an undisclosed number of high net-worth individuals.

There is a device similiar to the Star Wars halo thing. But this device is not a halo. It has something to do with the air to display images from the computer. This product is called Heliodisplay M2 projector, has been raving around for some time since around August 16, 2005. It is good for giviving presentations or displaying any products to anyone like giving an advertisement.

This projector costs $20,000.00. It is expensive, but it will go lower once it get very popular. Right now, business, musuems, expos use them. It will go to the home entertainement soon. It will be very cool!!! You can watch movie using this projector from your laptop or computer with DVD capability. It would be fun to sit back and watch in your own living room.

The heliodisplay is an interactive planar display. Though the image it projects appears much like a hologram, its inventors claim that it doesn't use holographic technology, though it does use rear projection (not lasers as originally reported) to project its image. It does not require any screen or substrate other than air to project its image, but it does eject a water-based vapour curtain for the image to be projected upon. The curtain is produced using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. This curtain is sandwiched between curtains of clean air to create an acceptable screen.Heliodisplay moves through a dozen metal plates and then comes out again. (The exact details of its workings are unknown, pending patent applications.)

It works as a kind of floating touch screen, making it possible to manipulate images projected in air with your fingers, and can be connected to a computer using a standard VGA connection. It can also connect with a TV or DVD by a standard RGB video cable. Though due to the turbulent nature of the curtain, not currently suitable as a workstation.The Heliodisplay is an invention by Chad Dyner, who built it as a 5-inch prototype in his apartment before founding IO2 technologies to further develop the produc

You can connect theHeliodisplay to any video output, or insert a CF (CompactFlash) card with AVI or JPEG files into the Heliodispay, and project any images or video in mid-air. Press the power button (eco-friendly, low power consumption 100watts, 280watts), connect the video source, and you will see images in air (some content is better than others). Heliodisplay prices range from $19,000 and 39,000USD (M50/L90) for the hardware, and more for turnkey solutions. 

IO2 Technology ships Heliodisplays worldwide. We can work with you to deployHeliodisplays in your location. Heliodisplays work on any power source, 90-240V, 50 or 60 Hz. No fog or special chemical is required. Heliodisplay does not affect the environment as it works using the existing air that is already in the room to create the image. An internal water tank of 8 liters filled with regular tap water lasts one to two days on the L90'' and a 3 liter tank on the M50'' lasts a day. A supplied water tank can be configured for operating continuously for a weeks, months or years
