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.

L'invention concerne un poste de travail visuel, destiné à un utilisateur et comprenant un dôme doté d'une extrémité antérieure ouverte et d'une surface intérieure sphérique tronquée. Une surface de travail est placée devant l'extrémité avant du dôme, est adjacente à cette dernière, et définit une zone de visualisation sur un côté de la surface de travail, opposé au dôme. La zone de visualisation est dimensionnée et conçue pour accueillir l'utilisateur et est positionnée en relation avec la surface intérieure sphérique du dôme, de façon que l'utilisateur, lorsqu'il se situe dans ladite zone, puisse visualiser la surface intérieure sphérique du dôme. Un projecteur est installé entre la zone de visualisation et le dôme, et il fonctionne pour projeter une projection sphérique tronquée sur la surface intérieure du dôme.
