Remember when we first saw the scene in Star Wars where Princess Leia appeared as a hologram image pleading for help? And you thought it won’t happen in real life? Check out this video. San Francisco Technology Reporter Gabriel Slate looks at this new way to display video on air. You can bring this invention home for $20K!

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 thereby creating an unobtrusive display. - IO2Technology
