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.

What is claimed is: 1. A system for processing one or more items, comprising: an acquisition device to capture indicia about an item moving along a path generally toward a display zone; one or more projectors positioned near said display zone where said item may be processed; a tracking system to c
What is claimed is: 1. A system for processing one or more items, comprising: an acquisition device to capture indicia about an item moving along a path generally toward a display zone; one or more projectors positioned near said display zone where said item may be processed; a tracking system to capture a plurality of locations and corresponding times for said item, said tracking system comprising one or more tracking cameras, wherein each of said plurality of locations comprises item coordinates relative to an established system of coordinates, an angular orientation relative to said established system of coordinates, and dimensional data about said item; and a controller in communication with said acquisition device, said tracking system, and said one or more projectors, wherein said controller receives said indicia from said acquisition device, selects a display based upon said indicia, and sends said display to said one or more projectors positions to project said display adjacent said item, wherein said controller is further configured to: receive said plurality of locations and corresponding times; compare said item coordinates to a fixed location of said display zone; and send a start signal to said one or more projectors when said item coordinates fall within said fixed location of said display zone, said start signal configured to prompt said one or more projectors to project said display. 2. The system of claim 1, wherein said indicia comprises an optical code and said acquisition device comprises an optical scanner. 3. The system of claim 1, wherein said indicia comprises a bar code and said acquisition device comprises a bar code scanner. 4. The system of claim 1, wherein said indicia comprises an RFID tag and said acquisition device comprises an RFID reader. 5. The system of claim 1, wherein said one or more projectors is positioned to project said display onto one or more exterior surfaces of said item. 6. The system of claim 1, wherein said one or more projectors is configured to select a most visible surface relative to a viewer located within said display zone, and wherein said one or more projectors is positioned to project said display onto said most visible surface. 7. The system of claim 1, wherein said one or more projectors comprises a laser projection system. 8. The system of claim 1, wherein said controller comprises a computer with memory and a database for storing said indicia. 9. The system of claim 1, wherein said display is configured to communicate a handling instruction to a viewer of said display. 10. The system of claim 1, wherein said display is selected from a set of standard displays. 11. The system of claim 1, wherein said controller is further configured to: select as a current location the most recent one of said plurality of locations; direct said one or more projectors to project said display adjacent said item at said current location, such that said display follows said item along said path. 12. The system of claim 1, wherein said controller is further configured to: select as a current orientation the most recent one of said angular orientations; direct said one or more projectors to project said display adjacent said item at said current orientation, such that said display follows said item along said path and remains legible. 13. A method of processing a plurality of items, comprising: (a) acquiring indicia about an item selected from a plurality of items moving along a path generally toward a display zone having a fixed display location relative to an established system of coordinates; (b) capturing a plurality of item locations and corresponding times for said item, wherein each of said plurality of item locations includes item coordinates and an angular orientation relative to said established system of coordinates; (c) selecting a display based upon said indicia; (d) projecting said display adjacent said item by comparing a current set of said item coordinates to said fixed display location and sending a start signal to initiate said display when said current set of item coordinates falls within said fixed display location; and (e) repeating steps (a) through (d) for a subsequent item selected from said plurality of items. 14. The method of claim 13, wherein said step of acquiring indicia further comprises providing an acquisition device configured to read said indicia. 15. The method of claim 13, wherein said step of projecting said display further comprises: projecting said display onto one or more exterior surfaces of said item. 16. The method of claim 13, wherein said step of projecting said display further comprises: selecting a most visible surface relative to a viewer located within said display zone; and projecting said display onto said most visible surface. 17. The method of claim 13, further comprising: projecting one or more of said displays simultaneously. 18. The method of claim 13, wherein said step of projecting said display further comprises: communicating a handling instruction to a viewer of said display. 19. The method of claim 13, wherein said step of selecting a display further comprises: providing a set of standard displays; and selecting said display from said set. 20. The method of claim 13, wherein said step of capturing an item location further comprises: capturing one or more intermediate locations of said item as it moves along a path generally toward a display zone; storing each of said one or more intermediate locations; selecting as a current location the most recent one of said one or more intermediate locations; comparing said current location to a fixed location of said display zone; and executing said step of projecting said display when said current location falls within said fixed location of said display zone. 21. The method of claim 20, wherein said step of capturing an item location further comprises: projecting said display adjacent said item at said current location, such that said display follows said item along said path and remains legible.
