The article provides information on the Heliodisplay from i02 Technology. The display exists in the air and the presenter can stand beside it, walk around it, and treat it like any solid object would be treated in its position. This Heliodisplay is interactive, like a virtual touchscreen. A hand or finger can act as a mouse; no special glove or pointing device is required. Just like any computer monitor or TV, images appear brighter the lower the ambient light and viewing a Heliodisplay in direct sunlight is almost impossible. Images can be seen up to 75° off aspect for a total viewing area of over 150°, similar to a liquid crystal display screen. Viewing requires no special glasses or background or foreground screening. The image is planar but like any computer monitor, it can project simulated three-dimensional (3D). Sometimes such images will look like real 3D when viewed from more than a few feet away because there is no physical depth reference for one's eye to base its vision on. The Heliodisplay connects to a computer through a USB port. It is backward compatible and accepts most two-dimensional video sources. For connection to a computer, the Heliodisplay uses a standard monitor video graphics array connection; for TV or DVD viewing, it connects using a standard red-green-blue video cable. In the course of developing the technology, i02 built Heliodisplays that displayed images ranging from 5 inches to 42 inches. The device can be oriented vertically or horizontally. Devices can be ganged together for one long continuous image and the technology can be customized for different applications, i02 believe the technology can be scaled up to at least 150 inch-images.
