Abstract
A visual workstation for use by a viewer includes a dome having an open front end and a truncated spherical inner dome surface. A work surface is disposed in front of and adjacent the dome front end. The work surface defines a viewer area on a side of the work surface opposite the dome. The viewer area is sized and configured to receive the viewer and is positioned relative to the spherical inner dome surface such that the viewer, when located in the viewer area, may view the spherical inner dome surface. A projector is disposed between the viewer area and the dome. The projector is operative to project a truncated spherical projection onto the inner dome surface.
Claims24
A visual presentation system comprising:
- a) a dome having an open front end and a truncated spherical inner dome surface, said spherical inner dome surface defining a front plane;
- and
- b) a projector operative to project a truncated spherical projection onto said inner dome surface, said projector including a terminal lens disposed within said front plane and/or within said dome.
A visual presentation system comprising:
- a) a dome having an open front end and a truncated spherical inner dome surface;
- and
- b) a projector operative to project a truncated spherical projection onto said inner dome surface, wherein said truncated spherical projection includes an axially asymmetric, truncated spherical image.
A visual presentation system comprising:
- a) a dome having an open front end and a truncated spherical inner dome surface;
- and
- b) a projector operative to project a truncated spherical projection onto said inner dome surface, wherein said projector includes a vertically oriented lens assembly, a horizontally oriented terminal lens and a mirror element between the lens assembly and the terminal lens.
A visual workstation for use by a viewer, said workstation comprising:
- a) a dome having an open front end and a truncated spherical inner dome surface;
- b) an exposed work surface adapted for use by the viewer, said work surface being disposed in front of and adjacent said dome front end, said work surface defining a viewer area on a side of said work surface opposite said dome, said viewer area sized and configured to receive the viewer and positioned relative to said spherical inner dome surface such that the viewer, when located in said viewer area, may view said spherical inner dome surface;
- and
- c) a projector disposed between said viewer area and said dome, said projector operative to project a truncated spherical projection onto said inner dome surface;
- d) wherein said truncated spherical inner dome surface has a maximum diameter of no more than two meters.
A visual presentation system for use by a viewer, said system comprising:
- a) a dome having an open front end and a truncated spherical inner dome surface;
- and
- b) a projector operative to project a truncated spherical projection onto said inner dome surface;
- c) wherein said truncated spherical inner dome surface has a maximum diameter of no more than two meters.
A method of displaying an image, said method comprising the steps of:
- providing an upright dome having an open front end and a truncated spherical inner dome surface, the inner dome surface defining a horizontal center axis and having a maximum diameter of no more than two meters;
- and
- projecting the image as a truncated spherical projection onto the inner dome surface.
