How Does the VisionDome Work?
 Via patented technologies, the VisionDome delivers a full-color, raster based, interactive display, with 360 degree projection and a 180 degree field of view. The tilted hemispherical screen is positioned so as to fill the field-of-view of the participants, creating a sense of immersion in the same way that large-screen cinemas draw the audience into the scene. The observer loses the normal depth cues, such as edges, and perceives 3D objects beyond the surface of the screen. The dome itself allows freedom of head motion, so that the observer can change their direction of view, and yet still have their vision fully encompassed by the image.
In contrast with the large format, analogue film used for entertainment in domed cinemas, the VisionDome is driven by digital media, either pre-recorded or generated in real-time from a computer or High Definition TV camera. Linked with compelling audio, the dome can temporarily suspend belief in the physical world and transport the audience into a virtual space. This provides the group equivalent of a Virtual Reality (VR) headset but without personally inhibiting hardware, and opens up a range of potential stand-alone and networked applications.
