How Do the VisionStation and
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 an immersive 3D
space but without personally inhibiting hardware,
and opens up a range of potential stand-alone and
networked applications.
Elumens' VisionDome
is an immersive digital environment that, via proprietary
projection and rendering technologies, creates
a full color, high-resolution, interactive, 3D
display in which a dozen or more people can simultaneously
participate and collaborate without having to use
restrictive head-mounted displays or goggles.
The VisionDome
projects a 360 by 180 degree panorama on the interior
of a dome, which is tilted from 0 to 90 degrees for
viewing ease. Because of the Dome's parallax effect,
how it engulfs viewers' fields of view, and Elumens'
proprietary rendering technology, the display creates
strong spatial 3D. This causes viewers to perceive
3D, and to feel completely immersed in the virtual
environment.
The VisionDome is designed to be deployed for 3D applications
in which many people need to participate jointly.
Since there is only one projection source and nothing
to wear, the VisionDome is the best solution for
collaborative environments. Because of its simplicity,
the VisionDome is a practical and cost-effective
alternative to head-mounted displays.
