A Projection Picking System (PPS) is an advanced, paperless, and light-directed logistics technology that uses projectors to display picking, sorting, and assembly instructions directly onto workstations, bins, or inventory. Using image processing and often 3D cameras, it guides operators in real-time, improves accuracy with built-in "Poka-yoke" (error-proofing) to instantly detect wrong picks, and increases productivity by 30-50%.
