Introduction
Introduction

  • Heliodisplay is a technology used for displaying images in mid air.

  • 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.

Working

  • The device converts the imaging properties of the air so that the air is taken in, converted instantaneously, and then re-ejected out

  • The system thus creates a dynamic, non solid particle cloud by ejecting atomized condensate present in the surrounding air

  • Now the projector projects the given input on the found invisible screen

Specifications
Specifications

  • 1024 x 768 resolution, 16:9 or 4:3 aspect ratios.

  • 2000:1 contrast ratio

  • Supports all formats

  • Projects any images that would be viewable on a computer screen or televison

  • No specialized hardware or software

  • 3D compatible


Advantages
Advantages

  • No screen to project images

  • Device is light weight and can be converted into a furniture

  • 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

  • Heliodisplay does not create fog, so no electronic devices in the room are affected

  • Heliodisplay can be used in any country since it works on 95-115 or 220-240 VAC

  • Heliodisplay, imagery can be seen up to 75 degrees off aspect for a total viewing area of over 150 degrees

  • No special glasses required to see the display

  • Translucency is controlled by the heliodisplay


Disadvantages
Disadvantages

  • Heliodisplay is very expensive

  • Viewing a Heliodisplay image in direct sunlight is almost impossible

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


Applications
Applications

  • Advertising/promotion

  • Video conferencing

  • Virtual surgery and pre-operative planning

  • Military training programs

  • Gaming/artwork

  • Engineering/architecture plans

  • Build the Heliodisplay into furniture



Fogscreen
Fogscreen

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

  • A real 3D image is generated by Perspecta display, which draws 2D images on a quickly rotating screen to fill the entire volume swept out by its path



Conclusion
Conclusion

  • Heliodisplay has great potential and would be ideal for collaborative work

  • Heliodisplays is still in the initial stages and the flaws of cost and environment of positioning will soon be overcome.

  • 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

  • Its various applications such as in advertising, a board room etc suggests that its future scope is very bright.
