<p>A work station at which an operator can perform manual tasks using the hands is modified by the addition of an indirect viewing system which includes an image generating system looking downwardly onto a work surface at which the hands of the operator are placed and the screen placed behind the work surface and viewed by the operator looking above the work surface. The work surface is preferably tilted to provide a negative tilt away from the operator at an angle of the order of 7°. The screen is preferably positioned so that it is at or slightly below horizontal from the eyes of the operator. The image generating system is preferably a television camera which cooperates with a monitor, both of which are mounted on a stand movable to the work station and adjustable relative thereto.</p> |
