A visual indexing system (10) for assisting placement of an object (36)
in a selected location upon a surface (16) moving in a selected direction
at a selected speed relative to a stationary frame is provided. The indexing system
includes a visual image generator (12) operable to project a visual image
(18) upon the moving surface such that the visual image is reproduced upon
the moving surface. The indexing system also includes a controller (14)
adapted to control the location at which the visual image generator projects the
reproduced visual image (18) upon the moving surface. The controller controls
the location of the reproduced visual image such that the reproduced visual image
moves in substantially the same selected direction and speed as the moving surface,
thereby resulting in substantially no relative movement between the reproduced
visual image and the moving surface.
