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. What the viewer sees is floating mid-air image or video. These projected images and video are two-dimensional, (i.e. planar) but appear 3D since there is no physical depth reference.

While conventional displays have the benefit of being attached to a physical substrate, Heliodisplay projections are suspended in air, so you will notice some waviness to the quality of the projections.
The Heliodisplay requires a power outlet, and a computer, TV, DVD or alternate video source. The current version of the Heliodisplay projects 30" diagonal images in 4:3 and 16:9 aspect ratio.
The Heliodisplay system is backward compatible and accepts most 2D video sources (PC, TV, DVD, HDTV, Video game consoles). For connection to a computer, the Heliodisplay uses a standard monitor VGA connection; for TV or DVD viewing, it connects using a standard video cable.
The Heliodisplay is designed to be concealed (i.e. into furniture) and hidden out of sight so that only the images are viewable. Heliodisplay can be built into different materials constructions (wood, plexiglas, metal, etc.). Hiding the source of the image make the projection even more attractive.
Although Heliodisplay images are easily viewed in an office environment, this system is unique, and therefore has to compete with it's surroundings, so contrast becomes paramount for optimal viewing.
Having a dark backdrop or background emphasizes the contrast of whites and blacks and is highly encouraged when designing a location to view the display. The same concept holds true for existing physical displays (LCDs, Plasma's etc), but contain a high contrast background when the pixels within image are not illuminated. Also, just like viewing any computer monitor or TV, viewing a Heliodisplay image in direct sunlight is almost impossible. Images can be seen up to 75 degrees off aspect for a total viewing area of over 150 degrees- similar to an LCD screen.
