Interactive Mid Air Display!    IO2 Technology has been developing the Heliodisplay, a mid air display which can project any video signal coming from most sources with one main difference, there is no screen. A projector is focused onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float, producing an effect much like a hologram. Images are visible under typical indoor lighting and are about as bright as the first-generation rear projection TV’s. The display works best under controlled lighting such as in museums, movie theaters, and most office spaces, although it is not recommended for outside use IO2 does build outdoor systems for enterprise solutions. The Heliodisplay’s default resolution is 800 x 600 to 1280 x 1024, depending on the model, a 22 to 42 inch image can be projected floating above the device, this can be viewed from 150 degree viewing angle in front of the projector or from both front and rear, again depending on the model. The Heliodisplay may be used as a touch-screen monitor to navigate and interact with content. When connected to a PC using a standard USB cable and the software provided you can use your finger, pen, pencil or any object to select and navigate as you would a conventional touch-screen, the only difference is that there is no physical screen.
