Viewing requires no special glasses. Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air. The Heliodisplay transforms water into a unique screen of fine vapour, suspended in mid-air to create a nearly invisible screen into which any image can be projected.

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. A hand or finger can act as a mouse. The Heliodisplay uses no additives or chemicals, repodt plain tap water you can also use distilled water, ionized water or demineralised water if desired.

Conventional displays have the benefit of being enclosed in a solid frame or case with lights shining directly towards the audience. The curtain is produced using similar ultrasonic technology as used in foggers and comprises a number of columns of fog.

Heliodisplay projections are suspended in thin air, so you will notice some waviness to the screen stability and the intensity and clarity of the image is subject to ambient light conditions and optimisation of display settings. Are you interested in this topic. These projected images and video are actually two-dimensional but appear 3D since there is no physical depth reference. Helioeisplay Heliodisplay connects to a computer at least: The display can create a true 3D hologram effect when the right content is used.

Though due to the turbulent nature of the curtain, not currently suitable as a workstation. Air comes into the device, is modified then ejected and illuminated to produce the image.

Heliodisplay Published on Dec 12, 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 product. The image is display into two-dimensional space i.

The Heliodisplay can be concealed i. The current version of the Heliodisplay projects a 22″ to 42″ depending on model seminr image that floats above the device. 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.

This curtain is sandwiched between curtains of clean air to create an acceptable screen. Images can be seen up to 75 degrees off aspect for a total viewing area of over degrees- similar to an LCD screen. The audience see a floating mid-air image or video. Just as you use a mouse to move the cursor on a traditional computer monitor, you can use your finger to move the cursor around the Heliodisplay image see: Nothing is added to the air so there isn’t any harmful gas or liquid emitted from the device.

Heliodisplay images appear 3D when viewed from more than a few feet heliodisplwy because there is no physical heliodislay reference. Viewing any type of display in direct sunlight is almost impossible and also applies to the Heliodisplay.

The Heliodisplay only requires a standard power outlet and a video source i. No special glove or pointing device is required. Heliodisplay moves through a dozen metal plates and then comes out again. The heliodisplay is an interactive planar display.

Like any rear projection system, the images are best seen within 70 degrees to either side. 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. Like any computer monitor or TV, images appear brighter the lower the ambient light.

Operating the device will not change a room’s environment, air quality or other conditions. Although the Heliodisplay uses lasers, the images are not holographic. Dark background emphasizes the contrast of the image and is highly encouraged when designing a location to view the display. Then mail to us immediately to get the full report. Also, just like viewing any computer monitor or TV, viewing a Heliodisplay image in direct sunlight is almost impossible.

The system is compatible with most video sources currently available. Although Heliodisplay images are easily viewed in an office environment, this system is unique, and therefore has to compete with its surroundings, so contrast becomes paramount for optimal viewing.

The exact details of its workings are unknown, pending patent applications. The Heliodisplay is interactive, like a virtual heliodisplaj.
