How does the Heliodisplay work?
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. The display can create a true 3D hologram effect when the right content is used. 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 audience see a floating mid-air image or video. These projected images and video are actually twodimensional but appear 3D since there is no physical depth reference. Conventional displays have the benefit of being enclosed in a solid frame or case with lights shining directly towards the audience. 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. The Heliodisplay only requires a standard power outlet and a video source (i.e. computer, DVD, video etc). The system is compatible with most video sources currently available. Heliodisplay uses a standard monitor VGA connection; for TV or DVD viewing, it connects using a standard video cable. The Heliodisplay can be concealed (i.e. into furniture) and hidden away from sight and thereby creating an unobtrusive display.

Above: Images under various ambient light conditions 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. Dark background emphasizes the contrast of the image and is highly encouraged when designing a location to view the display. Viewing any type of display in direct sunlight is almost impossible and also applies to the Heliodisplay. Like any rear projection system, the images are best seen within 70 degrees to either...
