1. An arrangement for collecting and automatically displaying information in real time along a line of sight from a human operator to remote targets located at variable distances therefrom, each target being identifiable by a machine-readable indicium associated therewith, the arrangement comprising: a) a housing aimable by the operator at the indicium of a respective target; b) a reader at least partly supported by the housing, for reading the indicium to obtain image data related thereto; and c) a projector at least partly supported by the housing, including i) a light source for emitting a light beam, ii) a scanner for sweeping the light beam in a pattern of scan lines on the respective target, each scan line having a number of pixels, and iii) a controller for automatically choosing selected pixels in the pattern based on the image data obtained by the reader, and for automatically causing the selected pixels to be illuminated and rendered visible by the light beam to automatically produce a two-dimensional image on the respective target adjacent the indicium associated therewith along the line of sight of the operator.
