Abstract
The invention includes a system for projecting a display onto an item or parcel using an acquisition device to capture indicia on each parcel, a tracking system, a controller or computer to select the display based on the indicia, and one or more display projectors. In one embodiment the display includes or connotes a handling instruction. The system in one embodiment includes a laser projection system to paint the selected display directly onto a selected exterior surface of the corresponding parcel, for multiple parcels simultaneously. The system may be configured to move each display in order follow each moving parcel so that each display remains legible to a viewer in a display zone where handling takes place.
