Introductiony Heliodisplay is a technology

used for displaying images in mid air.y In the heliodisplay, a projector

focuses the image onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float.

Basic units1. Base Unit 2. Projection Source

Working

y The device converts the imaging properties of the air so that the

air is taken in, converted instantaneously, and then re-ejected out y The system thus creates a dynamic, non solid particle cloud by ejecting atomized condensate present in the surrounding air y Now the projector projects the given input on the found invisible screen

Developments in heliodisplayy MODEL M1 y MODEL M2 y MODEL M3 and M30 y MODEL M50 and M100 y Model L90 y P-SERIES

Specificationsy 1024 x 768 resolution, 16:9 or 4:3 aspect ratios. y 2000:1 contrast ratio y Supports all formats y Projects any images that would be viewable on a

computer screen or televison y No specialized hardware or software y 3D compatible

Advantagesy No screen to project images y Device is light weight and can be converted into a furniture y Nothing is added to air. Nothing affects air quality projected images and video are two-dimensional, but appear 3D since there is no physical depth reference y Heliodisplay does not create fog, so no electronic devices in the room are affected y Heliodisplay can be used in any country since it works on 95-115 or 220-240 VAC y Heliodisplay, imagery can be seen up to 75 degrees off aspect for a total viewing area of over 150 degrees y No special glasses required to see the display y Translucency is controlled by the heliodisplay

Disadvantagesy Heliodisplay is very expensive y Viewing a Heliodisplay image in direct sunlight is

almost impossible y Screen is essentially air, so it can become distorted with too much air movement in the room

Applicationsy Advertising/promotion y Video conferencing y Virtual surgery and pre-operative planning y Military training programs y Gaming/artwork y Engineering/architecture plans y Build the Heliodisplay into furniture

Fogscreen

y Fogscreen is a display surface made out of a cloud of water vapor diffused into the air as a very dry fog

by Perspecta display, which draws 2D images on a quickly rotating screen to fill the entire volume swept out by its path

Conclusiony Heliodisplay has great potential and would be ideal for

collaborative work y Heliodisplays is still in the initial stages and the flaws of cost and environment of positioning will soon be overcome. y Several other thin air-displays are available but heliodisplay outclasses them, because of the attention it draws and its maintainability, and as a result it has more market value y Its various applications such as in advertising, a board room etc suggests that its future scope is very bright.
