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.
